Abstract

This paper identifies tax factors in 21 developing countries that have an impact on foreign direct investment flows. It categorizes those factors into issues associated with tax coordination; tax rates and rate structures; and composition of the tax base. Recent actions by countries reveal no clear pattern in their attempts to increase tax coordination, while many have reduced corporate tax rates and stream-lined tax incentives. However, broad-based tax reform is lacking in most, leaving room for further possibilities in tax reform for attracting foreign investment. The paper also addresses nontax factors that can be instrumental in attracting foreign investment.

I. Introduction

In recent years many countries initiated reforms in their tax systems that had similar objectives: broadening of the tax base, attenuation of progressivity, lowering the number of rates, reducing the number of taxes, dismantling of tax incentive schemes, and a concern for efficiency, high yield, and the ease of enforcement. This paper focuses on the potential impact of tax reform in developing countries on the international movements of capital. Section II discusses, at a descriptive level, the main tax and nontax factors that would affect foreign direct investment. Appendix I presents an analytical framework incorporating some of these considerations, while Appendix II elaborates on tax coordination experiences among different countries that would have important ramifications for foreign investment. Section III surveys salient parts of the tax structures of a selection of 21 non-OECD countries that are pertinent to a foreign investor, while Appendix III presents a set of cross-country tables delineating these features. Section IV presents available evidence of tax reform recently undertaken or in progress in the sample countries, with a focus on corporate income taxation as comprising the relevant investment inducing factors. Section V provides concluding remarks, highlighting the tax policies most conducive to attracting foreign investment.

This study does not discuss external financing of the government sector, and does not emphasize portfolio or financial investment. Rather, it seeks to identify the main factors—in particular, the tax factors—that are likely to have an impact on foreign direct investment flows. The study is based on available published material on the tax structures of the sample countries from various secondary publications, and the recency of the information, therefore, reflects that of these sources.

II. Factors Affecting Foreign Direct Investment

International investment is essentially mobile. Although the existing physical capital stock cannot be easily moved from one country to another, changes in host—recipient—country policies can affect the levels of existing capital if for no other reason but that physical capital depreciates and needs to be replenished by the foreign investor already operating in the country. This section describes the main features of a tax system that a potential foreign investor would consider important in making choices on the location of his investment: whether at home or abroad and, if it is the latter, which among possible foreign alternatives. Apart from the host government tax policies, however, there are many other complex determinants of the flow of foreign direct investment. Nontax economic considerations relating to the factors affecting the rate of return on capital investment obviously play a major role. Noneconomic factors, in particular the political and institutional environment in the host country, also weigh heavily in the decisions of the multinational firms on where to invest. Although the focus of this paper is on the role of the tax factors, it might be useful, by way of background, to mention the main nontax determinants of the flows of foreign investment.

1. Nontax factors affecting foreign direct investment

Nontax factors affecting foreign investment can be grouped into four broad categories. The first group relates to the political environment and stability of the country. Political risks which tend to deter foreign investment include the possibility of coups and revolutions that could lead to expropriation of private domestic or foreign capital, or to major disruptions in production and commerce. They also involve the possibility of reversal of policies, whereby the authorities fail to deliver the favorable business climate and adhere to the agreements as promised to foreign investors. Generally, the consistency of government policies in a potential host country in welcoming foreign investment and in honoring its commitments to foreign investors is an important factor in attracting foreign investors.

Second, the institutional and regulatory environment can also significantly hinder or promote foreign investment. Hindrances may take the form of direct prohibition (e.g., in some sectors foreign investment may not be allowed), a protracted decision-making process or excessive red tape in the screening, registering, and monitoring of foreign investment, or restrictions on the free working of the price system. Examples would be restrictions on access to both international and domestic credit markets (various forms of control as well as the requirement of minimum terms for foreign financing, limited access to domestic liquidity through bank or capital market borrowing), on foreign trade operations (limited access to foreign exchange, advance deposits for imports, requirement to surrender foreign exchange when the domestic currency is overvalued), restrictions on the repatriation of after-tax profits, and labor laws and practices in the form of restrictions that increase the cost of labor (impediments to hire or to discharge workers, absence of a clear framework for labor rights).

Capital importing countries may find that the creation of a climate favorable to investment from abroad is facilitated by their adherence to multilateral arrangements of guarantees to private international investment. One such arrangement is the International Convention on the Settlement of Investment Disputes, created to resolve through conciliation and arbitration disputes arising under investment agreements among member countries. Another is the Convention Establishing the Multilateral Investment Guarantee Agency (MIGA), aimed to protect and promote foreign direct investment in developing countries. 2/ Many countries have also engaged in bilateral agreements with the same purpose.

Third, macroeconomic policies play an important role on the formation of expectations about future economic conditions (Tanzi, 1989). A significantly overvalued exchange rate can be perceived by the potential investors as indicative of possible future restrictions on the flow of goods and capital in and out of the country and it increases the probability of large future devaluations. In order to protect their assets against such likely events, economic agents will not only avoid importing capital but may resort to taking capital out of the country (capital flight) or to holding foreign currency within the country (currency substitution). Consistently high public sector deficits generate expectations of inflation, tax increases, and macroeconomic instability in the medium run. Restrictive financial policies leading to negative real interest rates result not only in flight of portfolio capital but, by drying up the availability of domestic savings, also affect direct investment negatively. On the other hand, transparency and consistency in government policies and actions, and a clear and credible program of financing the government sector are conducive to establishing a healthy climate for attracting foreign investment.

A recent development in the category of macroeconomic policies that seems to have attracted some foreign investment has been the attempts by heavily indebted countries to facilitate debt-equity swaps as a way of reaching simultaneously the double objectives of reducing foreign debt and channeling new resources to investment. A debt-equity swap per se does not involve a net injection of capital into the host country but it changes the composition of the assets held by foreigners. However, if as a result of the swap, the foreign debt burden of the host country is alleviated, and thus the creditworthiness of the country and its prospects for better macroeconomic performance are improved, a climate of confidence emerges, attracting additional foreign investment.

Fourth, among the economic factors which affect foreign investment are also nontax incentives provided by the host government. Nontax incentives may take the form of reduced interest loans, cash grants, subsidization of certain inputs (e.g., energy, labor, transportation), and may be either generalized to all domestic and foreign investors in specific sectors or limited only to foreign investors. The tax system can be a major source of incentives or disincentives in more than one way and can accentuate or offset the sort of incentives and disincentives implicit in nontax factors described above. The next section discusses this issue.

2. The tax system and foreign direct investment

The fiscal parameters (e.g., tax rates, exemption levels, rules for base determination) that characterize a given tax system can be expected to influence the international allocation of a given pool of foreign capital. Although the impact of the fiscal parameters on the after-tax rate of return on investment is not the only determinant of the allocation of foreign direct investment, it could be crucial in the decision to invest in a given country. Its importance increases with the trend toward more freedom of movement for goods and capital, because liberalization tends to make investment more responsive to tax differentials among countries. At the same time, liberalization makes investment less dependent on the location of the sources of finance. As a consequence, tax policy changes in one country affects investment not only in that country but in other countries as well. In what follows, the main tax factors affecting the return to capital are reviewed with a focus on those features that are likely to especially affect foreign investors. Appendix I develops a simple framework delineating tax and nontax parameters on the rate of return of a unit of foreign (vis-à-vis domestic) investment, incorporating the main aspects likely to affect investment decision making across countries.

a. A focus on the corporate income tax

This paper focuses mainly on issues regarding the corporate income tax for the following reasons. First, it should comprise the most important tax element in a potential investor’s decision to invest. To the extent that capital exporting countries tax dividends received by their residents, regardless of where the income was generated—while the treatment of corporate income for tax purposes is more varied across countries—makes the personal income tax relatively less important than the corporate income tax for foreign investment decisions.

Furthermore, while companies may pay other taxes such as sales or turnover taxes, they do not directly affect the return to capital. Taxes such as the tax on wages and salaries withheld by firms, do not directly affect the company income and may be considered a burden on third parties since the company acts just as an agent for the tax administration. 3/ Other taxes enterprises may be required to pay include stamp duties, property taxes, and different types of fees. Such taxes are usually considered components of operating costs, and their burden is likely to be shifted to the consumers of the firm’s product. Accordingly, the present analysis is limited to the taxation of corporate income.

Almost every country has some type of tax on corporate income, although the tax structures among countries vary widely. Corporate taxation may differ in a number of ways other than the statutory rates, for example, the definition of the base, various incentives, and the treatment of profits earned abroad. Together they determine the effective rate of the corporate income tax and the net return to capital. These characteristics are discussed below in some detail.

(1) Criteria for tax coverage

Whenever a firm’s operations extend over two or more countries, a problem of tax jurisdiction arises: which state is entitled to tax the firm’s profits and dividends? Two basic criteria have been used in the case of dividends: the residence principle, according to which the firm is taxed in the country where it is headquartered, and the source principle, according to which the firm is taxed by the country where its operations take place and its income is generated. The effects of the implementation of the two criteria are not without ambiguities, however. The positions of capital importing and capital exporting countries are affected differently by the application of these criteria. Capital importing developing countries cannot accept the general application of the residence principle for the reason that nonresidents’ incomes constitute a considerable part of their tax base, though the use of the residence principle creates incentives for multinational companies to establish their headquarters in low or no tax countries, that is, tax havens. On the other hand, it is also possible that the residence principle puts the resident domestic investor at a competitive disadvantage vis-à-vis the foreign investor, especially when the host country has higher taxes than the home country because, in such a situation, the resident domestic investor would be subject to taxation by the host country, whereas the foreign investor would not. At the other extreme, a radical adoption of the source principle may not be feasible either, 4/ even though capital exporting countries usually accept its use in host countries and are virtually always ready to apply source taxation in combination with more or less consistent residence taxation, thus setting the stage for double taxation. There are, however, clear distinctions in the extent to which the priority of source country taxation is recognized. For instance, many capital exporting countries are ready to exempt foreign-source profits, even beyond the virtually generally recognized principle of deferral with respect to profits of foreign-based corporations. Fewer countries extend the same rule to dividends.

Another important source of differentiation in the international taxation of business income is in the definition of the corporate tax base. The majority of countries tax profits on an accrual basis. 5/ The cash basis method is often reserved for the taxation of small businesses. In the assessment of the tax, all revenues due to operations, sale of assets, and incidental revenues are summed up, and the corresponding costs and expenditures are deducted from this sum. Since excessive deductions may be claimed, the tax codes often include detailed rules attempting to draw a line between what is and what is not deductible. These rules can differ significantly from country to country. Attempts to define precise deductibility criteria by tax legislation are less than fully successful, since it is virtually impossible to anticipate the diversity of situations created by the business activity. Therefore, there is the need to establish some general principles to apply to the “gray areas” with the purpose of minimizing tax avoidance and litigation. A general deductibility criterion is the principle of normality, according to which those expenses that are reasonable and commonly incurred by other taxpayers in the same sector of activity are deductible. Another is the principle of necessity whereby deductions are allowed only for the operating costs which have to be incurred to ensure the sustainability of the firm’s operations. Therefore, in addition to the company tax rate, a clear and reliable definition of the tax base is also essential in the determination of the tax burden on, and the net rate of return to, foreign capital. A more burning issue is perhaps the recognition or nonrecognition of costs incurred abroad, in particular, head office expenses on behalf of the foreign subsidiary or branch, technical assistance given to them by the head office or parent company, and so on. This problem gets acerbated when the home country applies stringent rules on the allocation of costs.

(2) Depreciation rules

The cost involved in the wear and tear of capital goods (buildings, machinery, vehicles, furniture, etc.) is recognized through the imputation of a fraction of the value of the goods on the current costs. Since economic depreciation, which would include market obsolescence, is difficult to determine, tax regulations usually rely on a short table of estimated lives of capital goods for the determination of the depreciation rates, which are then applied to the book value of the assets.

Depreciation rules vary substantially across different tax systems. The straight-line method writes off a constant value over the lifetime of capital. A few countries require, and many countries offer as an option, the use of the declining balance or written-down value method, whereby the rate applies to the previous book value. 6/ Given the same life span of an asset, the declining-balance method would be more advantageous to the taxpayer than the straight-line method since it would have to allow a larger depreciation at the beginning. Less common methods of depreciation include various forms of accelerated depreciation: for example, initial allowance, whereby a sizable proportion of the investment is cost-recovered in the first year and the balance is depreciated either by straight-line or declining-balance; the (declining) sum of the years’ digits method, whereby the assets are depreciated each year at a linearly declining rate; 7/ and immediate expensing, whereby the total amount of the investment is deducted as cost in the first year of operation. Inflation may require special adjustments in depreciation, a matter discussed later.

As a measure intended to provide incentives to specific activities favored for the purpose of developing certain sectors of the economy, several countries have introduced accelerated depreciation and depletion allowances applicable to some types of projects for which foreign investment is most needed (e.g., oil exploration). Accelerated depreciation allowances improve the cash flow to the firm, and in effect may operate as an interest-free loan from the Treasury to the firm, reducing the costs of financing the acquisition of new capital. This depends, of course, on the existence of otherwise taxable profits within the same jurisdiction. Furthermore, accelerated depreciation enables quick recovery of the cost of investment and reduces the recovery risks in the long run. On the other hand, it is not an attractive incentive for new foreign investors who count on initial losses.

Costs of intangible assets can be recovered through rules similar to depreciation rules. For example, patents and exploration rights have a time frame specified by the host country’s laws or a bilateral contract between the country and the foreign investor. Pre-operational or pre-production expenditures are usually written off in a specified number of years after operation or production begins. Clearly, the more generous the rules for the recovery of such costs, the faster the recovery of investment, and the greater the incentive for the foreign investors to invest in a host country.

(3) Deductibility of interest

Interest on corporate debt is normally considered a legitimate cost, therefore the composition of capital, as summarized by the debt/ equity ratio, affects the tax liability. As a result, with the purpose of minimizing the tax liability, 8/ the firms may exhibit a preference for debt financing as opposed to equity financing. The issue of attracting foreign investment gets somewhat reversed in this particular case for, in principle, foreign investors are in a better position than domestic investors to disguise as debt the equity capital transferred to the host country and claim undue tax deductions. 9/ The problem is made more acute when the host country creates “excess profits” taxes, or sets limits to dividend remittances, thereby creating an even greater incentive to disguise transfers of profits as interest payments on debt. Such response by the taxpayer to a possible asymmetry between debt and equity financing created by the differentiated treatment under the corporate income tax is referred to as thin (or hidden) capitalization in the tax literature.

A solution for thin capitalization, such that the financing ratio were neutral to the corporate tax, is hard to find. In some developed countries practical rules to overcome this problem are being considered. A radical solution may consist of disallowing the deductibility of interest, while enacting a compensating reduction in the statutory tax rate so as to keep the tax revenue constant. By this criterion, the base of the tax would be expanded to reach all value added attributed to capital, whether it is due to dividend or interest earnings. The major drawback of this approach is that it may increase the tax burden on businesses which are temporarily recording true losses without resorting to thin capitalization schemes. An alternative is to allow the firms to deduct interest on debt and also imputed interest on equity in the determination of the taxable profit; however, at the same time the statutory tax rate would have to be raised in order to compensate for the narrowing of the tax base so that the tax revenue remained unchanged. A third method, virtually the only one implemented so far to deal with the problem of thin capitalization, consists of setting a ceiling for debt equivalent to a multiple of the value of equity (Canada, the Netherlands, Switzerland, the Federal Republic of Germany, and the United States). When the ceiling is exceeded, the corresponding interest is not deductible, or is deductible only if the taxpayer is able to provide evidence that the entire debt is contracted under normal market conditions, and that the creditor does not have control of the equity capital of the debtor, or vice versa. This solution, by providing a relatively clear-cut criterion, provides the authorities with an effective tool to detect abuses. Its main disadvantage is that it could encourage firms to practice their capitalization up to the legal ceiling. To conclude, for a developing host country, the possibilities of thin capitalization might comprise a disguised incentive for attracting foreign investment.

(4) Valuation of inventories

According to standard accounting principles, inventories of raw materials and intermediate and finished products are recorded at the historical cost of acquisition or production. 10/ However, inventories are undervalued under the historic cost principle of accounting if there is persistent inflation. Three basic criteria have been utilized for the valuation of inventories, with different impact on costs. Under the first-in-first-out (FIFO) method, the costs of stock at the end of the year are calculated on the basis of the price of the oldest acquisition of stock. As a result, with FIFO accounting, inventories sold are valued below their replenishment cost, if prices are increasing; hence, nominal profits and tax liability increase. Under the last-in-first-out (LIFO) method, the costs of stock at the end of the year are calculated on the basis of the value of the inventories and stocks sold accordingly valued on the basis of the most recent price; therefore, nominal profits calculated under this method are less likely to be distorted by inflation, that is, the tax liability is not unduly increased. A third method, the average cost method, determines the unit value of every inventory item as a weighted average of the most recent acquisition price (or cost of production) and the previous average unit cost. The value of inventories so determined is then used to derive the production or sales cost. The impact on the tax liability implied by this method is intermediate between LIFO and FIFO. 11/ In cases of high inflation in capital importing countries, there would have to be some latitude for the firms to choose the method of inventory valuation so as to minimize any unintended increase in the tax burden.

(5) Treatment of capital gains

Capital gains are often taxed more lightly than recurrent income. This difference in tax treatment is motivated, inter alia, by the desire to provide incentive to investment, and to minimize the “lock-in effect.” 12/ In recent years, however, several countries have moved in the direction of uniform taxation of recurrent and nonrecurrent income. The reasons for this trend are no less compelling than those for differential tax treatment. 13/ First, in practice, there is always the problem of distinguishing recurrent from nonrecurrent operations. The differential tax treatment may lead to litigation on borderline operations, which is costly to the taxpayers as well as to the tax authority. Second, the existence of differential tax treatment interferes with business decisions in ways not intended by the tax legislation. For example, if profits in the stock market—when stock is held for, say, at least six months—are taxed as capital gains and not as current income and at the lower rate, trade in stocks held for four or five months would be inhibited, creating market inefficiencies. Third, differential taxation of capital gains makes the overall tax liability of the businesses less predictable due to the difficulty involved in separating the recurrent and nonrecurrent components of income. The criteria of transparency and ease of enforcement have been important determinants of the growing consensus that capital gains should be taxed at the same rate as ordinary business income. Fourth, it is worth mentioning that the definition of capital gains itself tends to differ in different legal systems. Quite a few countries have uniform treatment as ordinary income of all gains on business assets, while maintaining the privileged treatment of capital gains on assets outside business. Also, most countries do not even attempt to reach nonresidents with capital gains tax on their dealings in shares of resident companies.

Thus, unification of rates goes a long way toward simplifying the overall taxation of business profits, and thus may be conducive to attracting further investment.

Unification does not, however, remove problems which are peculiar to capital transactions. Large payments might require tax deferral to avoid an undue cash squeeze on the company. A second issue is whether net capital losses—occurring when capital losses exceed capital gains—can be applied against profits in current operations. If that is not allowed, net capital losses should be carried backward or forward to be written off against net capital gains from other periods. Third, the taxpayer, if given the right to deduct capital losses from other income elements, may gain by realizing his losses while postponing the realization of gains. Thus, symmetric treatment of unrealized capital gains and losses would also need to be preserved.

(6) Loss carry-backs and carry-forwards

Operating losses made in a given year not only preclude corporate tax liability for that year but usually also entitles the firm to a credit against future or past tax liabilities, that is, to a carry-forward or carry-back of losses. Carry–backs are less common because they involve tax refunds, which tax authorities are less willing to grant, and they usually extend over fewer years than carry-forwards. Carry–forwards are typically granted for four or five years, 14/ but much longer periods—even indefinite—for carry-forwarding also exist in practice. Intertemporal compensation of losses can be granted through adjustments in the tax base or through tax credits. Generous loss carry–forward allowances in a country will increase the net rate of return, making that country more attractive for foreign investment.

(7) Adjustments for inflation

Absence of inflation adjustment in the assessment of corporate tax would result in an effective increase in the tax burden in most instances. For example, when the depreciation allowances are assessed at historic cost of capital, the tax base and therefore the tax liability is larger. Another example is the case of loss carry–forward which, without inflation adjustment, becomes less and less significant in real terms over time. Inflation adjustment features in tax rules could be important in attracting foreign investment to capital importing economies that have experienced high rates of inflation, and despite current stabilization policies.

Inflationary adjustment involves the indexation of tax rules on depreciation, inventory valuation, and other cost items which determine the taxable income, including capital gains and, to be more appropriate, the valuation of assets as well as the valuation of liabilities (or change in net worth). Indexation is usually carried out on the basis of some price index, for example, the consumer price index. However, indexation of the tax base requires comprehensive and complicated accounting procedures to be followed by the firms, which in turn calls for complicated tax laws and regulations. Thus, as comprehensive inflation accounting becomes necessary, the corporate tax regulations could become increasingly complex.

Though inflation adjustments usually affect the assets side, full indexation would include the liability side as well. Therefore, in many systems, going from partial indexation to full indexation could be viewed as a negative development by investors.

Inflation may also affect tax liability directly whenever the corporate income tax is not proportional but has a progressive structure. In this case, failure to adjust the tax brackets in a timely fashion will cause “fiscal drag”—a phenomenon that puts taxpayers in ever increasing income tax brackets at the same real incomes during high inflation (Shome and Dalton, 1986)—commonly observed in the case of personal income tax since the personal income tax is progressive in most countries, and indexation of the tax schedules is incomplete. In such a case, particularly due to the fluctuations in the expected inflation rate when there is price instability, the expected tax liability becomes volatile, increasing the risks associated with investment.

(8) Exchange rate adjustments

An overvalued exchange rate creates distortions similar to inflation in the absence of adjustment. For example, the cost of the goods imported at the beginning of the production period in terms of domestic currency is understated at the end of the production period when the firm’s income is realized and the company income tax liability occurs. Given the tax rate, the tax liability rises because the base is larger in the absence of exchange rate adjustment, which reduces the net rates of return. Thus, an overvalued exchange rate can be seen as a deterrent to foreign investment in a given economy.

b. System of withholding taxes

Most host countries usually withhold tax on certain types of income such as dividends, interest, royalties, and management fees transferred abroad. The usual treatment is to tax the partner on his share of the partnership’s income and hold the resident partner or the manager in charge responsible for the tax to be paid, with recourse to the property of the partnership. In order to encourage reinvestment, some countries exempt capitalized profits from the remittance tax conditional to the permanence of the new capital for a stated period, say five years, typically paying only the corporate income tax. If repatriation is made before that time, forgone taxes are due, sometimes with accrued interest. Some countries, in order to maximize investment incentives, set a rather low rate on the corporate tax while establishing a higher level of withholding tax on dividends for the purpose of inducing reinvestment; but with respect to interest, royalties, etc., paid to third parties, no such motive would be involved.

c. Branch profits taxes

Gradually, there is more widespread use of branch profits taxes. Most countries recognize the difficulty in taxing dividends paid by foreign corporations to nonresident shareholders, even if these dividends are based on profits made by activities in the host country where the foreign corporation has a permanent establishment. They may require local incorporation, in which case, they are in a better position to tax first, the profit, and then, the dividend. But they may also accept the branch arrangement while, at the same time, claiming tax in lieu of dividend withholding tax on remittances from the branch to the head office. Normally, a branch profits tax based on actual remittances is too difficult to administer. Therefore, the more common practice is to impose an additional tax on the branch profit, normally related to the dividend withholding tax. 15/ This could be expressed in the simple form of a higher corporate tax rate applying to nonresident corporations. Some opposition has been heard against branch profits tax as discriminatory but after its introduction by the United States in 1986, it seems to have diminished.

d. Corporate wealth taxes

In view of the difficulties in assessing taxable profits, policymakers in some countries have tried to tax the corporate sector through a levy on its net worth. Clearly, this is an imperfect way to reach corporate income for taxation purposes, since companies with significant wealth may also be incurring losses. Profitable companies with a lower level of assets may end up paying less tax than they would under a single corporate profits tax, whereas unprofitable companies with a high level of assets may face higher taxation. The corporate wealth tax may lead to uneven taxation in relation to profits, which may deter prospective investors. These investors will also see as a strong negative element that a corporate wealth tax normally is not creditable against home country profits tax.

e. Minimum corporate tax

Different forms of the corporate wealth tax might also be thought of as a proxy for the corporate income tax. In application, the conventional corporate income tax may be an unproductive source of revenue in view of its complex nature which leaves room for tax avoidance. Indeed, it is not uncommon to observe that some companies manage to stay in business year after year, generating a positive cash flow, while showing consistent accounting losses. In order to deal with this problem without creating a new and separate corporate wealth tax that could compound the existing difficulties, policymakers have devised mechanisms to contain the erosion of the corporate tax base. The minimum corporate income tax—often taking the form of a percentage of turnover, but sometimes related to corporate gross assets—may be applied as a credit against the corporate income tax, so that the company would be paying either the corporate income tax or the minimum corporate tax, whichever is higher. This would ensure that at least a minimum amount of taxes would be collected from every business. While a modest minimum tax may not have a strong negative impact, overdoing it may deter investors, not least because the tax may then not be creditable against home country tax (Mutén, 1982).

f. Tax incentives

During the 1950s and 1960s, it was quite popular to utilize tax incentives to pursue many different objectives, including attracting foreign investment. With time came the realization that the results were more modest than anticipated. The lack of transparency of tax expenditures, as well as their relative effectiveness compared to out-right subsidies, came to be questioned (Sanchez-Ugarte, 1987). Tax incentives have gradually lost their appeal also on equity grounds, since they tend to favor those with the highest ability to pay. Yet, they are often seen as a necessary evil, not least if countries are seen competing for investors’ interest.

It would go beyond the scope of this study to examine the various types of, and motivations for, incentives, but the picture that emerges from the corporate tax laws allows the grouping of tax incentives in the following main categories: (1) deduction of actual payments or imputed expenditures that otherwise would not be considered deductible; (2) deduction of costs and expenditures by a multiple of the amount actually incurred; (3) accelerated depreciation (see (2) above); (4) partial or total exemptions from the corporate tax for a specified or unlimited time (tax holidays); (5) tax credit for the whole or for a fraction of some types of capital expenditures; (6) permission to earmark a part of the tax payment as a deductible contribution to some funds and programs; and (7) creating tax havens (Casanegra-Jantscher, 1976).

The long-term impact of tax incentives on foreign direct investment is not obvious, although it is clear that firms will be looking for ways to reduce their tax liabilities. For example, tax holidays could lead to a postponement of investment toward the end of the holiday period when accelerated depreciation would begin to apply since a potential investor could be interested in the “average” (over the years) tax burden rather than “marginal” (holiday period) incentives (Auerbach 1990). Also, it has been argued that incentives such as tax holidays effectively represent a temporary lowering of costs that could fuel future inflationary expectations and lead, again, to a postponement of investment. If the incentive mechanism is not believed to be sustainable, entrepreneurs could shy away from long-term commitments, 16/ and it has been argued that, in any event, tax incentives tend to encourage short-term investment. A case can be made that the best environment for attracting foreign direct investment, given other prerequisites (viz., nontax factors), is not one of generous tax incentives but of relatively low tax rates for all business and a low government deficit, which would contribute to convincing prospective investors that the tax environment is indeed stable and durable.

g. Tax coordination

In a world where capital is mobile, tax systems become interdependent. Whenever interdependency occurs there is scope for coordination. 17/ Yet, international coordination on tax matters is still in its infancy. On the whole, there has been little sustained effort to date on the part of the general international community to coordinate taxation despite its potentially augmentative impact on foreign investment. Tax coordination has, however, been attempted within regional country groupings. Some of these are reviewed in Appendix II, together with a discussion on ways in which taxation—especially taxation affecting foreign investment—can be coordinated among countries. In general, there has been little coordination in capital income taxation in regional country groupings including the EC, confined primarily within bilateral tax treaties. Indeed, as discussed by Tanzi and Bovenberg (1990), there is a need to harmonize capital income taxes within the EC as the Community moves toward a unified market with free capital movements and fixed nominal exchange rates.

In practice, most capital exporting and capital importing countries have unilaterally introduced their own mechanisms, either dispensing with all taxation of income from abroad, or putting in place one or more mechanisms of tax relief. Tax deferral is a method in which the taxation of profits made abroad is deferred until they are repatriated. 18/ From a revenue viewpoint the least costly of such schemes for the capital exporting country is tax deduction, whereby the tax paid abroad is deducted as a necessary expense. A scheme with a higher degree of neutrality on the allocation of investment is tax credit, whereby the profits made abroad are taxed only to the extent the domestic tax liability on the foreign income exceeds that incurred in the host country. 19/ In this case, for the capital importing country there is a range of rates within which to move without adversely affecting foreign investment—on the assumption that the international investor does not care about where the taxes are paid. Finally, tax sparing is a particular feature of the tax credit arrangement whereby taxes forfeited by the host country as investment incentives are treated by the home country as tax liabilities.

The foreign tax credit has been adopted by many countries in tax treaties but also unilaterally, and the reasons for its popularity may rest less in generosity than in feasibility. On the one hand, by being a unilateral device it may be simpler to set up, operate, and modify than cooperative schemes, while on the other hand, operations conducted abroad are to some extent out of reach of tax enforcement authorities; a high level of overall domestic taxation on investment abroad is difficult to enforce (Mutén, 1982).

3. Summing up

This section has highlighted the main tax and nontax aspects determining the relative attractiveness of a host country for foreign investment. The tax factors can be consolidated under four broad groups comprising: (a) issues associated with tax coordination; (b) tax rates and rate structure; (c) composition of tax base; and (d) other determinants, but their importance should not necessarily be linked to their order of appearance since that would tend to depend on the overall circumstances of an individual country.

The role of tax coordination and tax treaties cannot be minimized in the decision making of a potential foreign investor. For example, their role in resolving the basis for dividend taxation can be quite important. Thus, it would not be practical for a host country to tax a foreign investor too highly on the basis of the source principle when he is also taxed at home on the basis of the residence principle. Augmented efforts at tax coordination at various levels would aid in the resolution of potential conflicts arising out of the use of different bases of taxation across countries. More generally, tax coordination in a global context, or even within regional groupings or bilateral arrangements that reduce the risk attached to returns on investment would support foreign investment.

With respect to issues regarding tax rates and rate structure, while a low nominal rate of the corporate tax may not by itself comprise a sufficient incentive for the potential foreign investor, tax reform leading to successive and substantive reductions in tax rates could be presumed to affect investment favorably. Similarly, a rate structure that is proportional rather than progressive is more attractive in that it reduces “fiscal drag.” In the same vein, overall simplicity in the rate structure that avoids differential taxation of different types of economic activity, certainly improves the foreign investment potential.

The determination of the effective corporate tax base, which is the result of the tax treatment of various cost items, is of paramount importance. For example, are deductions arbitrarily limited or unduly restricted with respect to costs incurred abroad? Ambiguous definitions of base could imply an implicit tax burden and would be a deterrent to attracting foreign investment. Also, forms of accelerated depreciation that improve the cash flow to firms and enable quicker recovery of investment costs as against straight-line depreciation are preferred provided there are profits to deduct them from. Inventory valuation rules—LIFO as against average cost (or even worse, FIFO)—to assure the least tax liability; or some latitude in choosing the most appropriate method of inventory valuation by each firm within the bounds of accepted accounting principles, are of great importance in particular contexts such as that of high inflation. In general, the incorporation of proper inflationary adjustments regarding tax rules on depreciation, valuation of assets and inventories, as well as capital gains would affect the tax base as well as comprise an important element in the potential foreign investor’s decision making. Generous “recovery rules” for pre-operational expenditures, as well as loss carry–over provisions are also considerations that a potential foreign investor would tend not to ignore. Last, but not least, while various specific types of tax incentives such as tax credit, tax holidays, and investment allowances continue to play an important role in the statutes dealing especially with foreign investment, their role in attracting foreign investment has increasingly been questioned by tax experts as substitutes for a simple overall tax structure.

There are other tax factors that are also likely to be important. For example, the rates and base of the capital gains tax could affect the foreign investor, and a corporate wealth tax is especially perceived to lead to inequitous burdens even though it might be a useful proxy for the corporate income tax for domestic companies. Withholding taxes on dividends, interest, royalties, etc., in general, tend to be accepted by legitimate foreign investors, but might weigh heavily on their decision to invest if they are perceived to be levied at prohibitive rates. Branch profits taxes are gradually winning acceptance as imposed in lieu of withholding tax on dividends. Finally, the treatment of foreign exchange gains and losses for tax purposes would affect a foreign investor’s taxable income, and their treatment as regular taxable income/loss would be appropriate.

In conclusion, in his decision to invest abroad, a foreign investor is likely to take account of nontax factors that have to be complementary to a favorable tax environment. These would include: political stability; existing institutional and regulatory framework including protection of and restrictions on foreign investment, access to international as well as domestic credit, labor market provisions and practices, as well as infrastructure and access to markets; and macro policies that include stabilizing influences such as debt-equity swaps in heavily indebted countries as well as an overall policy environment that tends to reduce capital flight, currency substitution, and the like.

III. Tax Structure and Foreign Direct Investment in Selected Non-OECD Economies

Based on information drawn from published sources, this section surveys the evidence regarding those aspects of the tax systems that seem to bear on foreign investment. A sample of 21 non-OECD countries has been chosen: Anglophone Africa—Kenya, Malawi, Nigeria, Zimbabwe; Francophone Africa—Côte d’Ivoire, Morocco, Senegal; Middle East—Pakistan, Saudi Arabia; Asia—China, India, Indonesia, Korea, Singapore, Thailand; Latin America—Argentina, Brazil, Mexico, Venezuela; and Eastern Europe—Hungary, the U.S.S.R. It also describes selected nontax features currently prevalent in these economies that are likely to have broad ramifications for foreign investment.

1. Nontax factors 20/

a. Protection of and restrictions on foreign direct investment (Table 2)

The scope, conditions, and guarantee (in some form) of foreign investment is covered in most of the sample countries either formally through a foreign investment act (Kenya, Nigeria, Zimbabwe, Morocco, Korea) or through stated government policy (India, China, Thailand, Argentina). In some countries, provisions for nationalization or expropriation with compensation are included (India, China, Indonesia, Mexico) while others guarantee against it (Pakistan, Thailand, Korea). Other countries may not have any overall legislation—depending more on bilateral arrangements—yet there may be little or no restrictions or conditionality on foreign investment except for registration or authorization (Côte d’Ivoire, Senegal, Saudi Arabia, Singapore, Argentina, Brazil).

Most countries do, however, impose some restriction or conditionality on the form, location, or purpose of foreign investment. Some countries are more restrictive than others, for example, forbidding foreign investment in certain sectors (“negative list”—Nigeria, Morocco, India, Korea, Brazil, Venezuela). Most countries stipulate local equity participation, exceptions being Côte d’Ivoire, Senegal, Singapore, Brazil. India puts a ceiling of 40 percent on foreign equity, while other countries stipulate minimum local participation (25 percent in China and Saudi Arabia; 20 percent in Indonesia, but having to rise to 51 percent within 15 years of operation) or group industries into those in which majority foreign equity is allowed or those where it is not (Nigeria, Thailand, Mexico).

In most countries, there are no restrictions on the repatriation of interest, dividends, royalties, fees, or equity on liquidation or sale of business. They are, however, usually subject to proof of deduction of withholding tax, if any (i.e., a tax-clearing certificate) to be presented to the central bank (Kenya, Malawi, Nigeria, India, Venezuela). Some require prior approval or permission (Korea, Thailand, Argentina, Mexico). While there are no requirements regarding the reinvestment of profits, some countries apply occasional dividend repatriation limits by putting them in blocked or suspense accounts (Kenya, Nigeria, Zimbabwe), or require reinvestment to increasingly use domestically produced machinery (Korea).

b. Accessibility of international capital markets and local borrowing (Table 3)

As can be expected, access to international capital markets is permitted in all cases but is subject to various types of control in all countries (except Singapore) such as approval by the central bank (Kenya, Malawi, Morocco) or the Ministry of Finance (Nigeria, Zimbabwe, Côte d’Ivoire, Senegal—though for the last two countries, no approval is necessary within the French Franc Zone), or through stipulation of costs (Argentina—interest rates may not exceed LIBOR plus 1 percent; Mexico—interest costs not deductible; and Venezuela—interest rate on foreign loans between affiliated companies subject to a ceiling).

Local bank borrowing is allowed in all countries—in some without limitations (Saudi Arabia, Thailand, Korea, Indonesia, Singapore) while in others it is subject to certain limitations (confined to specific sectors—Kenya, Nigeria; limited to a percentage of aggregate paid-in capital—Venezuela; allowed in proportion to local shareholders’ share in total equity—Kenya, Malawi, Zimbabwe, Morocco; decided in view of the company’s financial situation—Côte d’Ivoire, Senegal; in tandem with credit restrictions on domestic companies—India, Argentina, Mexico; or repayable within a specified period—Nigeria).

Local capital markets exist in the majority of countries—Kenya, Malawi, Zimbabwe, Morocco (though for a limited number of national companies), Côte d’Ivoire, Pakistan, India, Thailand, Korea, Indonesia, Singapore, Argentina, Brazil, Mexico, Venezuela—but access to them by foreign investors is again subject to limitations in most of them (except Côte d’Ivoire, Indonesia, Singapore) based on criteria such as local shareholders’ share in equity (Kenya, Argentina), specified requirements for listing on local stock exchange (Zimbabwe), approval by the Ministry of Finance or central bank (Pakistan, India, Korea), or depending on the borrower, whether local or foreign investor (Venezuela).

c. Debt-equity swaps

Debt-equity swaps for foreign investors are not of any significance in the sample countries under discussion except in Argentina and Venezuela where they are allowed under specified conditions, and Mexico which only recently suspended its debt-equity swap program. In Argentina, they require an additional investment in foreign or local currency totaling 30 percent of the project cost. In Venezuela, debt-equity swaps are available for investments in selected sectors subject to limits on the repatriation of dividends and capital.

2. Tax factors

a. Tax jurisdiction (Table 4)

The basic residency criterion for a company in all sample countries is local incorporation except in Argentina where there is no concept of a “resident company” for tax purposes. Some of the countries have additional attributes: physical presence of a registered office (Malawi, Pakistan, India); location of head office (China, Korea, Brazil, Mexico); management and control of business exercised from host country (Singapore).

The source principle is the basis of taxation in the sample countries, that is, income derived from host country operations is taxed. However, once residency is established, Pakistan, China, Korea, Thailand, and Mexico tax worldwide incomes, while Singapore taxes foreign income remitted to Singapore. Information on attribution rules, that is, criteria applied for determining inter-country allocations of income and expenditure was not available for all countries, but the general indication is that countries attribute incomes and expenditures at “arm’s length,” that is, the tax authorities of the host country expect the foreign investor to account for such transactions between parent company and subsidiaries as well as between head office and branches at prices and conditions as if they were between separate and independent entities (Nigeria, India, Argentina, Brazil; but generally, all countries have such rules in one form or another). In Mexico and Venezuela, the tax commissioner’s discretion determines attribution while in Senegal, a pro-rata basis is applied to turnovers for each (branch) country if separate accounts are not available. 21/

The number of capital exporting countries with which each sample country has tax treaties varies, but many have tax treaties with major West European and Nordic countries, and some also with the United States (Kenya, Malawi, Morocco, Pakistan, China, Korea, Singapore, the U.S.S.R., Argentina). Some countries stand out for their differences: Nigeria has treaties with the British Commonwealth and the United States; Zimbabwe with the United Kingdom and South Africa; Senegal and Saudi Arabia with France; India’s treaty net with Europe is close to complete, whereas the United States treaty is not yet ratified, India also plays a leading role in concluding South-South treaties; and Thailand and Brazil not with the United States but with Japan, Canada, and selected EC countries (and also Nordic countries for Brazil); while Venezuela is currently negotiating with the United States and some EC countries.

The treatment of taxes paid abroad and of foreign income varies in the sample. The most common form is tax credit: Kenya (only in the case of treaty), Nigeria, Zimbabwe, Senegal, Argentina, Brazil (in those cases where foreign income is taxable), Pakistan, India, Korea, China, Indonesia, Singapore (only for income tax, in treaty as well as non-treaty countries). Some countries do not tax foreign income: Malawi, Senegal (in most instances), Côte d’Ivoire, Saudi Arabia. A few countries allow income deductions for foreign taxes paid: Kenya, Senegal (in those cases where foreign income is taxable). Mexico applies differentiated tax rates on profit remittance depending on the level of taxes paid abroad, and Venezuela does not provide for any special treatment for foreign companies or subsidiaries.

b. Rate structure of taxes (Table 5)

The standard rate structure of the corporate income tax can be grouped in different ways:”. (1) few versus wide-ranging multiple (3 or more) rates; (2) 40-50 percent range, those primarily below this range, and those above; (3) differential rates among domestic, foreign, and joint ventures; and (4) rates differentiated by sectors. First, the multiple rate countries are Saudi Arabia (4 rates), China (8 rates plus surcharge where applicable), Indonesia and Venezuela (3 rates). Second, those in the 40-50 percent range are Kenya, Malawi, Nigeria, Zimbabwe, Côte d’Ivoire, Morocco, India (brought down by 10 percentage points to 40 percent in 1990), Hungary, the U.S.S.R.; those primarily below are Senegal, Saudi Arabia, China, Indonesia, Korea, Pakistan, Singapore, Thailand, Argentina, Brazil, Mexico, Venezuela. While some of the sample countries levy surcharges, their rates are not high enough to shift them from the overall groupings. Third, countries that tax domestic companies differently from foreign or joint ventures are Kenya, China, Korea, Thailand, Argentina, Hungary, the U.S.S.R.—all generally applying a lower rate for foreign or joint ventures; only Kenya and India impose a higher tax rate for foreign compared to domestic companies. Fourth, countries with mineral or petroleum resources have higher tax rates for this sector—Côte d’Ivoire, Saudi Arabia, Indonesia, Thailand, Venezuela, while Hungary and China use differentiated sectoral tax rates. The most complicated standard corporate income tax nomenclature is ostensibly that of China.

In most of the sample countries, capital gains are taxed at the regular income tax rates—Côte d’Ivoire, Morocco, and Senegal (in all three, full exemption applies if reinvested but, in the last, only for capital gains from fixed assets), Senegal, Saudi Arabia, China (in sectors where applicable), India, Indonesia, Korea (with selected surtaxes), Thailand, Hungary, the U.S.S.R., Argentina, Brazil, Mexico, and Venezuela. In a few countries, they are taxed at a lower rate—Nigeria, Zimbabwe, Pakistan; while three countries, Kenya, Malawi, and Singapore, do not tax capital gains.

c. Tax bases (Table 6)

The bases of both capital gains and corporate income taxes perhaps comprise the most important determinants of the final tax burden that a foreign investor would bear on his returns made in a host country. The effective base is the result of various tax deductions, allowances, credits, holidays as well as valuation principles for depreciation, inventories, and assets. As can be expected, these are specified in a wide variety of ways in the sample countries and the actual calculation of effective burdens would be a significant exercise for each of them.

The base of the capital gains tax is quite broad in some of the sample countries and include gains from both physical and financial capital (Côte d’Ivoire, Morocco, Senegal, Korea, Indonesia, Argentina, Brazil, the U.S.S.R.), but in most the base comprises only certain parts of overall capital (all properties other than government securities—Nigeria; immovable property and securities—Zimbabwe; fixed assets—Saudi Arabia, China; all properties excluding stocks—India; properties excluding immovable properties and shares of public companies—Pakistan; profit-motivated properties—Thailand; fixed assets and shares—Mexico; immovable property and shares—Venezuela). Even in those instances where the base is broad, taxation usually relates to gains under specific conditions (number of years held—Morocco, Senegal; size of shareholder in overall stock position—Senegal, Korea; size of specified assets in overall asset position—Korea).

The effective base of the corporate income tax is made even more complicated through the multiple factors that affect it. Among deductions, asset price is based on historical value in all countries; in Argentina and Brazil the historical value is adjusted for inflation. For depreciation calculations, some countries use a single formula while others allow alternative methods: straight-line—Nigeria, Zimbabwe, Saudi Arabia, China, while in Argentina, Brazil, and Mexico, it is inflation adjusted; declining-balance—Pakistan (except straight-line for ships), India; formula varies according to asset—Kenya, Côte d’Ivoire, Morocco, Senegal, Pakistan, Korea, Indonesia; any generally accepted method—Thailand, the U.S.S.R., Venezuela; by government ordinance—Hungary. For inventory valuation, many countries use cost or market value (Kenya, Malawi, Zimbabwe) and, within them, most use the lower of the two thus making it the “standard rule” (Nigeria, Côte d’Ivoire, Morocco, Senegal, Pakistan, India, Singapore, Thailand, Venezuela). 22/ Some countries cannot be grouped easily: Saudi Arabia uses only cost; China uses a variety of methods—FIFO, moving average and weighted average, while Indonesia and Brazil use FIFO and moving average; Korea allows all methods; Argentina uses LIFO, and Mexico allows immediate expensing. Information on loss offsets was not available for many countries but among those available two groups are possible: indefinite carry-forward (Kenya, Malawi, Zimbabwe) and three- to five-year carry-forward (Nigeria—four, Côte d’Ivoire—three, Morocco—four, Senegal—three, Hungary—five and extendable, Argentina—five, Brazil—four, Mexico—five, Venezuela—three); Saudi Arabia does not allow loss offsets. From the above, it may be concluded that the different factors that reduce the base of the tax do not move in unison in the sample countries so that it is difficult to rank them in terms of a favored foreign investment status, a task that becomes all the more difficult when investment allowances, tax credit, and tax holidays are considered.

Except Saudi Arabia, India, and the U.S.S.R., all sample countries grant investment allowances, tax credit or both. Those that grant investment allowances are: Kenya, Malawi, Nigeria, Zimbabwe, Morocco, Indonesia, Singapore, Brazil; India abolished investment allowances in 1990. Those that use the tax credit method are: Pakistan, China, Korea, Hungary; those that use both instruments for incentives are: Côte d’Ivoire, Senegal, Thailand, Argentina, Venezuela. Tax holidays are utilized in most countries for specified sectors other than Kenya, Malawi, Zimbabwe, Senegal, India, Argentina, Brazil, Mexico. Countries using them may be grouped into two broad categories: those with a maximum five-year holiday period (Nigeria, China, Thailand, Korea, and the U.S.S.R. for joint though not solely foreign ventures) and those heavily leaning toward five- to ten-year holiday periods (Côte d’Ivoire, Morocco, Saudi Arabia, Pakistan, Indonesia, Singapore, Venezuela). In Hungary, the Government uses its discretionary powers. In addition, the sectors to which the holiday applies vary across the sample countries and encompass agriculture (Nigeria, China, Venezuela, the latter two including forestry), manufacturing (Nigeria, Côte d’Ivoire, Pakistan, Korea, Singapore, Thailand, for high technology industries, Venezuela), mining (Nigeria, Côte d’Ivoire, Morocco, Pakistan, China, Indonesia, Venezuela), shipping (Morocco, Korea), tourism (Côte d’Ivoire, Morocco, Venezuela), export industries, offshore financing, international trading companies, and investment promotion zones (Singapore, Thailand). Saudi Arabia grants blanket holidays to all development projects according to the Foreign Capital Investment Code while the U.S.S.R. Government decides them for all “special activities.”

d. Withholding taxes (Table 7)

To some extent, a corporation’s decision to invest abroad can be seen to depend on withholding taxes on dividends in the host country, whether it is final, as well as whether the tax paid by the company is imputable to the shareholder. With respect to the latter, only a few countries make the company tax imputable: Kenya, Malawi, Nigeria, Singapore, Thailand (mainly using tax credits) and, in India, Argentina, Brazil, Mexico, and Venezuela (dividends paid to corporations are exempted). With respect to a withho1ding tax most countries impose it in the range of 10-20 percent; with India and Brazil exceeding that range at 25-30 percent, and the U.S.S.R. being below that range at 5 percent; while Saudi Arabia, Singapore, Hungary do not withhold. Withholding is final in Zimbabwe, India, Korea, Indonesia, Argentina, Brazil, Mexico, and Venezuela—mainly for nonresidents—a tax credit against tax due on “grossed up” receipts being used in the other cases.

e. Available evidence on the treatment of foreign exchange gains and losses (Table 8)

Among other tax factors that may play a role in his decision making for investment abroad, a foreign investor would consider the tax treatment of foreign exchange gains and losses. In the sample countries, exchange gains and losses are treated as ordinary income in the countries for which information is available: Kenya, Nigeria, Côte d’Ivoire, Morocco, Senegal, Saudi Arabia, Korea, Singapore, Thailand, Hungary, Argentina, Brazil, Mexico (here only inflation-adjusted gains are taxed); in the U.S.S.R. it is treated as capital gains (but capital gains and corporate tax rates are the same).

3. Summing up

Among the more restrictive nontax environments are probably India and China, neither of which rules out expropriation or nationalization, while applying a ceiling on foreign equity, or a floor on local participation, or a negative list ruling out foreign investment in selected sectors. Other countries that seem to follow with various degrees of restriction appear to be Indonesia, Mexico, and Brazil. However, there seems to be little restriction on repatriation in the sample countries as a whole. The countries with the least restrictions appear to be Côte d’Ivoire, Senegal, and Singapore.

Foreign investors are, in general, technically allowed to borrow from the local banks as well as capital markets but most countries impose restrictions on such access in one form or another. Access to international capital markets is similarly restricted. Singapore is the least restrictive, followed by Côte d’Ivoire and Indonesia. The Latin American countries tend to link borrowing with interest costs. India again appears to use restrictions applicable to domestic investors as well as other administrative controls.

The source principle is the primary basis of taxing the returns on foreign investment in all countries, with some modifications applicable in a few of them. Also, the general indication is that most countries apply the “arm’s length” attribution rule as is to be expected for the minimization of tax avoidance. There is little clear pattern in bilateral tax coordination, though nine of the sample countries have concluded treaties with West European and Nordic countries as well as the United States, and a majority of them provide “spontaneous” tax coordination through tax credit or deductions from gross income. Also, it cannot be concluded that the countries that rely on spontaneous coordination are the ones that have not concluded the most bilateral tax treaties.

While most countries have nominal corporate tax rates below 40 percent, nine have higher rates; hence, there is scope for reductions in the nominal rates. On the whole, the rate structure is relatively complicated across the sample countries with ample room for simplification toward a single rate. Two countries that have simplified their structures in recent years are Indonesia and Mexico. Finally, surcharges on the corporate income tax that may effectively be a branch profits tax might play some role over and above that of the rate and rate structure of the corporate income tax.

The corporate income tax base is quite diverse across the sample countries as it is affected by different rules on asset price, depreciation, inventory valuation, and loss offsets, inasmuch as by a variety of tax incentives. Asset price valuation is based on historical cost in all countries; therefore, there is room for introducing inflation adjustment (Argentina and Brazil already have it). Depreciation rules are stringent in many countries inasmuch as they adhere only to the straight-line method. These countries could compare depreciation rules with other, especially neighboring, countries for similar assets in order to gauge possible differences in the inducement to invest. For inventory valuation, most countries effectively use FIFO; only Argentina uses LIFO, Mexico allows immediate expensing, and Korea allows all methods. If attracting investment is the objective, other countries would follow the Korea model. A few African countries allow indefinite loss carry-forward but most do not extend beyond a three to five year range which appears to be the norm. Similarly, the bases of the capital gains tax can be seen to be quite diverse. While recognizing that country-specific factors often typify the actual structure of such a tax, there still seem to be significant possibilities for simplification in many instances from the point of view of the investment objective.

Tax incentives are used in some form or other by most countries, the most popular form being tax holidays for selected sectors, while a few countries use tax credit as well. Developing countries hopeful of attracting foreign investment should study carefully the ramifications of such tax incentives. As was indicated earlier, the role of such incentives in encouraging foreign investment might not always be positive because tax incentives may, in general, encourage only short-term investment, tax holidays may lead to postponement of investment if there are inflationary expectations, foreign investors may prefer a simple tax statute rather than one riddled with multiple interpretation possibilities and, hence, subject to discretion and, last but not least, they would perhaps attach greater weight to the overall stability of the economic environment rather than to a complex system of incentives.

Withholding taxes are levied by most countries in the range of 10-20 percent which seems to be the norm, except for India and Brazil which impose it at 25-30 percent, where there would be some room for reductions. A minority of countries allow imputation of the company income tax usually using tax credits; while a few others only exempt dividends paid to corporations. Most countries need to reform their tax structures in this area. Finally, most countries exempt emigrants’ remittances except India which taxes it as the recipient’s income.

IV. Recent Tax Reform Experience

This section provides recent available evidence from the sample countries of recent measures pertaining to those aspects of the tax structure with potential ramifications for foreign investment. During the 1980s, when the United States began to contemplate tax reform with the objective of improving the supply-side response of tax policy, a number of other industrial, developing, and centrally planned economies also started reviewing the prospects for carrying out tax reform. By the end of the decade, many countries had implemented reforms in the prevailing tax systems in varying degrees and forms in the expectation of promoting growth by minimizing distortions for the use of factors of production, including foreign capital. Many countries concentrated, as the United States did in its 1986 Tax Reform Act, on the income tax by attempting to simplify its structure by broadening its base and lowering its rates. 23/ However, some others such as Indonesia, Singapore, and Venezuela went beyond income tax reform by overhauling their entire tax structure and introducing new taxes.

It may be argued on theoretical grounds that a reformed tax structure on the whole, comprising not only the corporate income tax but also others such as the personal income tax and consumption taxes, improves the economic environment by reducing price distortions, encouraging simplicity and improving clarity of tax burdens. However, it is beyond the scope of this paper to enter into the overall ramifications of the structural reform of all taxes. This section of the paper will, therefore, concentrate mainly on corporate income tax reform, in host countries, that seems more directly pertinent for foreign investment decisions. Regarding the other two taxes, suffice it to say that there was a switchover from the sales tax to some variant of the value-added tax in Kenya, Morocco, Pakistan, Indonesia, Thailand, and Venezuela; and the nominal personal income tax rates were reduced in about half of the sample countries, accompanied by a broadening of the base in selected cases.

1. Reductions in tax rates

Most sample countries revised their corporate tax rates, some notable exceptions being Côte d’Ivoire, Malawi, and Saudi Arabia; while Zimbabwe increased it (Table 1). Centrally planned economies, namely China, Hungary, and the U.S.S.R. also carried out reforms by introducing standard tax systems as prevalent in market-based economies. The extent of reduction in corporate tax rates varies. In the case of Hungary, the 60 percent tax rate applicable to foreign-owned companies was reduced to 40 percent in 1989 (plus a 4 percent additional tax on 1988 income) depending on profit levels. Other countries reducing their highest rates by substantial percentage points included Pakistan (15), Argentina (13), India (10), Indonesia (10), Korea (10), Singapore (8), and Mexico (7). Those reducing their tax rates by 5 percentage points or less included Nigeria, Venezuela, India, Thailand (5 in each case), and Kenya (2.5).

2. Broadening of the tax base

Broadening of the corporate tax base was attempted through the elimination of tax holidays upon their expiration or shortly thereafter (Venezuela, Singapore); reduction of extent and duration of tax holidays (Korea); removal of investment allowances (India); reduction in the number of tax-exempt industries (from 44 to 6 in Pakistan); and a detailed scrutiny of existing exemptions (e.g., the establishment of a Registry for the Industrial Promotion Tax Benefits in Argentina to facilitate an accurate measure of the tax revenue that the Treasury had waived). In Brazil, the Constitution created an annual budget of tax expenditures. In some instances, the initial payment of the corporate income tax was imposed as a fixed proportion of the net worth of the enterprise which then applied as a credit toward the payment of actual income tax liability to reduce the erosion of real revenues (Argentina, Mexico). However, Mexico also introduced full indexation of business profits and assets. In one instance, provision was made for the payment of minimum company tax along the same lines as in the United States (India). In Venezuela, the scope for tax avoidance through an artificial de-integration of companies producing the same or complementary product was eliminated by requiring such companies to consolidate their incomes for tax purposes, while Korea laid down clear rules for transfer pricing. Finally, Kenya abolished the capital gains tax, and Argentina the net wealth tax.

In the process of broadening the tax base, a number of countries simplified incentives while providing new incentives especially for foreign investment. For instance, India relaxed residency rules so as to attract savings from nationals living abroad. Mexico provided a tax break to nationals repatriating their funds back to the home country. Saudi Arabia reduced effective tax rates for both domestic foreign financial institutions—banks and insurance companies—by allowing nonperforming loans and insurance commissions as deductible costs. Some countries, however, introduced new investment incentives geared to specific objectives. Korea and Singapore introduced special accelerated depreciation allowances on high technology machines and equipment. India extended full tax exemption to income derived from export earnings of industries, while the U.S.S.R. introduced a two-year income tax exemption to all joint ventures.

In Mexico, relief was provided to shareholders by introducing partial imputation of the company income tax. However, in other countries special incentives provided to promote savings by exempting certain interest income from taxation (India, Korea), or granting other forms of special treatment (Venezuela) eroded the tax base. In Argentina, dividend incomes which were previously not taxable were made taxable in the hands of shareholders, with a partial imputation of the tax paid at the corporate level. The bases for net wealth and stamp taxes were widened to include certain hitherto not included assets (Korea, Singapore) and transactions (Argentina). The enforcement of income tax laws was intensified on the basis of visible evidence from business and individual taxpayers (Korea).

3. Summing up

Many of the sample countries have started reforming their tax systems. Among features of tax reform that would affect foreign investors especially, it might be noted that corporate tax rates have been reduced in most countries in recent years, with Hungary, Pakistan, Korea, and Indonesia reducing it by 10 percentage points or more. A few countries have also attempted to broaden the corporate tax base by eliminating tax holidays and streamlining tax incentives in general, while others expanded various incentive schemes that eroded the tax base. However, broad-based tax reform has been lacking in most countries, leaving room for further simplification, broadening of the base, and rate reductions. On the whole, much seems yet possible in tax reform with the objective of attracting foreign investment.

V. Concluding Remarks

The paper has attempted to (1) discuss tax and nontax factors likely to affect foreign investment; (2) review those parts of the tax systems of selected non-OECD countries that are likely to have ramifications for decision making by a foreign investor; and (3) provide available evidence on the tax reform experience in the sample countries especially those pertinent to foreign investors. Cross-country comparisons revealed a wide variety of tax structures as well as scattered instances of reforms in recent years to attract foreign investment. Doubtless, room remains for further tax reform in these countries if greater foreign investment is the objective.

The review of the main features of business profits taxation reveals a wide range of determinants such as definition of taxable profits, rules for depreciation, inventory valuation, treatment of capital gains and operating and capital losses, adjustments for inflation and exchange rate changes, tax incentives, and tax coordination. As far as tax policy is concerned, governments which want foreign investment to play a role in their development programs are well advised to design their tax structure with an eye to the taxation level in the other countries which are potential competitors as venues for foreign investment. In addition, the overall economic climate is a major determinant of foreign investment. It is up to each national government to develop the institutional, fiscal, and monetary policy climate so that the international investor responds to the given environment. 24/ Moreover, within each country, the overall level of foreign investment is probably determined inasmuch by domestic institutional and political forces as by the economic policy environment. Thus, the effective tax burden, as well as the overall economic policy and politico-institutional environment are all important determinants of foreign investment.

Although every country is either a net importer or a net exporter of capital, it is often the case that it exchanges capital with the rest of the world. Since it is reasonable to assume that resident investors react to the same set of incentives as foreign investors, it follows that the same factors and policies that serve to attract foreign investment also work to retain within the country the capital owned by domestic residents. Conversely, when capital has incentive to move abroad the domestically owned part does not necessarily stay behind. Therefore, the need for the use of tax instruments to prevent capital flight is apparent.
