A previous IMF Working Paper on value-added tax (VAT) refunds (WP/07/31, by Keen and Smith) describes the main forms of VAT noncompliance and concludes that VAT is susceptible to evasion and fraud like any other tax. This paper shows the insidious nature and extent of VAT refund fraud in selected EU countries and argues that this type of noncompliance requires tax administrations to adopt a coordinated strategy and deploy a range of countermeasures to combat this threat. Because such fraud is primarily a criminal legal issue, tackling it successfully will require cooperation, both internationally between VAT administrations and nationally between tax authorities and the judiciary. The paper’s focus is primarily on advanced economies in the context of the EU, but many of the recommendations are applicable to emerging market and developing countries. A separate IMF How to Note discusses managing VAT refunds in developing countries.
Turnover taxes are prevalent in developing countries as a simple form of presumptive taxation of business income. Such simplified tax regimes can reduce the relatively high compliance costs of micro and small enterprises, which might otherwise discourage entrepreneurs from formalizing their activities and paying taxes. The note addresses design issues for a turnover tax regime—which taxes it replaces, what the criteria are for eligibility, how to determine the optimal threshold, and how to set the tax rate. A key observation is that, although low turnover tax rates may incite larger firms to artificially reduce their sales, the rate should also not be so high as to discourage formalization of activities. A table of tax rates and turnover thresholds observed internationally is provided. The note concludes by suggesting analytical steps to guide practitioners in designing turnover tax regimes.
