The Revenue Statistics in Latin America and the Caribbean publication is jointly undertaken by the OECD Centre for Tax Policy and Administration, the OECD Development Centre, the Inter American Center of Tax Administrations (CIAT), the Economic Commission for Latin America and the Caribbean (ECLAC) and the Inter-American Development bank (IDB). It compiles comparable tax revenue statistics for a number of Latin American and Caribbean economies, the majority of which are not OECD member countries. The model is the OECD Revenue Statistics database which is a fundamental reference, backed by a well-established methodology, for OECD member countries. Extending the OECD methodology to Latin American and Caribbean countries enables comparisons about tax levels and tax structures on a consistent basis, both among themselves and between OECD and OECD economies.
