    Preface

    A central role of the IMF is to help member countries reduce the risks of macroeconomic instability, particularly by strengthening their public sector institutions. To this end, the Fiscal Affairs Department (FAD) provides technical assistance to member countries to strengthen tax revenue performance by improving the organization and operations of the tax administration. Much work has been undertaken by FAD analyzing the requirements for and impact of tax administration reform in developing countries. One area, however, that has not been reviewed at the IMF—or elsewhere—is the growing focus on different segments of the taxpayer population, including the large taxpayers, as a way to encourage greater stability in public revenue flows, improve the effectiveness and efficiency of tax administration, and introduce innovation in the public sector (e.g., new organization, procedures, and systems in the tax department, as well as improved services to taxpayers).

    Based on a sample of about 40 countries, this paper provides an overview of country practices in terms of the organization, systems, and procedures used by tax administrations to monitor the compliance of the large taxpayers. The paper also reviews the effectiveness of large taxpayer operations in selected developing and transition countries where the IMF has recommended their establishment.

    There are, of course, limits to this kind of analysis, given the complexity of measuring taxpayer compliance, the shortcomings of the data reported by tax administrations in many developing and transition countries, and the short time series available for several countries that have only recently established specialized large taxpayer operations. Certainly this review is not intended to be a handbook on how to set up a large taxpayer unit. The analysis does, however, provide a sense of the major challenges facing developing and transition countries in the process of modernizing their tax administrations, particularly for large taxpayers, as well as some of the approaches being taken to address these challenges.

    This paper was prepared by an International Monetary Fund staff team led by Katherine Baer and comprising Olivier Benon and Juan Toro. The authors note that the paper benefited from the review and comments of many colleagues, including Jean-Paul Bodin, Isaias Coelho, John Crotty, Paulo dos Santos, Richard Highfield, Seth Terkper, Nobuhiro Tsunoda, Koenraad van der Heeden, and James Walsh. The authors also wish to thank Milka Casanegra de Jantscher, Michael Keen, Carlos Silvani, Emil Sunley, Günther Taube, and Teresa Ter-Minassian for their insightful comments and suggestions, and Gail Berre, Joan Gibson, and Ann Robertson, who edited the paper for publication.

    Overview

    Beginning in the 1980s, the IMF has recommended that member countries facing revenue crises and looking to strengthen tax administration establish large taxpayer units (LTUs) to increase control over the largest taxpayers 1 and improve large taxpayers’ compliance in the short and medium term.2

    This paper provides an overview of the organization, systems, and procedures used by tax administrations in about 40 countries to monitor the compliance of the large taxpayers. It also reviews the effectiveness of large taxpayer operations in selected developing and transition countries where the IMF has recommended their establishment.3 Information provided by tax officials in the countries surveyed, as well as IMF staff and IMF experts’ views on the effectiveness of large taxpayer operations in these countries, form the basis for this discussion.

    Case analysis indicates that countries may gain significant benefits from setting up special operations to control the compliance of the largest taxpayers. It also shows that certain risks need to be addressed. Clearly, the experience of many developing and transition countries shows that setting up special operations to control large taxpayer compliance has resulted in increased compliance and more effective tax administration overall. Such special operations have focused tax administration efforts on relatively few taxpayers that account for a large percent of total tax collection. Many of the countries surveyed reported that establishing an LTU helped them address major operational weaknesses in tax administration and improve core tax administration functions. In addition, in many countries the LTU has been a pilot for the tax administration to test reforms later extended to the rest of the taxpayers. These include the self-assessment of taxpayer liabilities, single taxpayer master files, unique taxpayer identification numbers, an organizational structure based on the main tax administration functions, electronic filing, and new computerized information systems.

    The trend to establish LTUs or organizational arrangements based on large taxpayers in developing and transition countries is similar to efforts in developed countries (e.g., Australia, France, the Netherlands, New Zealand, the United Kingdom, the United States). Tax administrations in these countries are reorganizing their operations around segments of the taxpayer population (especially according to taxpayer size) because the various segments require different strategies to manage their tax compliance and also because these distinct segments present different revenue risks.

    At the same time, risks are associated with establishing an LTU that tax administrators and other public finance officials should consider. If the LTU is only partly established.4 it will not reach its potential to improve the operations of the tax administration and increase large taxpayer compliance. Thus, not only is an important opportunity for reform lost, but the LTU loses credibility as a vehicle for modernizing tax administration. Unfortunately, there are several such examples among the transition countries.

    Sustaining the reforms introduced through the LTU, and extending the modernization to the entire tax administration—including the tax offices dealing with small and medium-size taxpayers—have been major issues for several countries. Without consistent political and management support, as well as the needed financing and staff. LTUs that were initially successful can succumb to the same problems that existed before their implementation.

    Further risks specific to the operation of the LTU include overemphasizing the administration of the large taxpayers and ignoring the medium-size and small taxpayers; failing to provide specific types of controls for the large taxpayers (e.g., those to ensure compliance with return filing and payment obligations); assigning too many taxpayers to the LTU, thereby rendering compliance management ineffective; and allowing irregular or corrupt practices by LTU officials who are not properly supervised. Related to this, a major challenge for tax administrations setting up an LTU is to attract and retain staff of sufficient caliber to audit complex operations, provide large taxpayers with accurate and up-to-date information, and create a professional work environment that discourages tax officials from engaging in corrupt practices.

    Finally, to gauge the effectiveness of the LTU’s operations and changes in large taxpayer compliance, tax administrations must identify and compile performance indicators, which are the basis for effective management reporting.

    Against this background and from the IMF’s experience in assisting member countries to set up and manage large taxpayer compliance operations, important lessons have been learned.

    • For the LTU to be effective and for the large taxpayers’ compliance to improve significantly, the government must fully commit to setting up the LTU, providing it with the necessary resources (staffing, physical infrastructure, computers, etc.), and supporting auditing and enforced collection for the largest taxpayers.

    • The long-term effectiveness and credibility of the LTU depends on the government’s ability to incorporate the LTU into a broader tax administration reform. This is an area where the IMF could improve follow-up of the initial LTU reform effort.

    • The LTU needs continued reform and modernization, like the rest of the tax administration, to remain effective and to keep up with changes in the economy and the taxpayer population.

    • For an LTU to work properly, it must meet certain minimum requirements (many of which are also applicable to the overall tax administration), including

      • ♦ A sound legal framework;

      • ♦ Clear and none criteria for selecting large taxpayers;

      • ♦ Standard and transparent procedures;

      • ♦ The administration of all the large taxpayers by the LTU;

      • ♦ The administration of all national level domestic taxes by the LTU;

      • ♦ LTU performance of all core tax administration functions;

      • ♦ Clear reporting lines between the LTU and the headquarters office;

      • ♦ Appropriate job grading and remuneration of LTU staff;

      • ♦ Effective LTU staff training; and

      • ♦ Identification and regular compilation of key performance indicators.

    • Even if these conditions are met, the establishment of an LTU cannot strengthen large taxpayer compliance and generate added revenue when there is prolonged downturn in the economy.

    • The experience of the transition countries with LTUs suggests that a positive relationship exists between the successful implementation of an LTU and progress in macroeconomic stabilization and other structural reforms, including tax policy reforms.

    • The most effective LTU operations are based on strong, centralized supervision of operations and limited organizational units. In contrast, the least effective LTUs seem to be those that are highly decentralized.
