Tax Expenditure Budgets: Concepts and Challenges for Implementation
Dec 2009
Tax expenditures are generally defined as those government expenditures carried out through tax legislation, regulations, and practices that reduce or defer taxes for some taxpayers. There is a general concern that the tax expenditures negatively affect the budget and tax policies, which in turn affect the transparency, efficiency, and equality of the fiscal systems. Many countries in Latin American and a few in the Caribbean already estimate their tax expenditures; but in many cases they do so without adopting a consistent methodology that allows for adequate comparisons or that even evaluates their effectiveness. This working paper discusses the conceptual aspects of tax expenditures, the main challenges to assess them, and the general procedures adopted in the OECD countries and Latin America and the Caribbean to calculate, present, and approve them.
