This report on Colombia is part of the OECD Tax Policy Reviews series. OECD Tax Policy Reviews are intended to provide independent, comprehensive and comparative assessments of OECD member and non-member countries’ tax systems or zoom in on a specific country tax policy topic. By benchmarking the tax systems of countries and identifying tailored tax policy reform options, the main objective of the Reviews is to enhance the design of existing tax policies and to support the adoption and implementation of tax reforms.

In 2021, the Tax Incentives Commission (TIC) identified the need for Colombia to develop a stand-alone Tax Expenditure (TE) report and to strengthen the measurement of the tax revenue foregone of TEs. Following up from the TIC report, Colombia requested OECD assistance in defining its TE benchmark and to provide technical support to improve the measurement of tax revenue forgone from TEs.

This OECD Tax Policy Review proposes a benchmark for the taxation of Income and Valued Added Taxes and seeks to identify the full list of TEs within the Colombian tax system. It provides an in-depth assessment of Colombia’s TE reporting practices and makes specific recommendations as to how the measurement of TEs and the reporting of them can be improved. Finally, it provides item-by-item estimates on the revenue forgone from all the TEs within the corporate and personal income tax that can be estimated given the available data. The report was prepared in close collaboration with Colombia’s Dirección de Impuestos y Aduanas Nacionales (DIAN) and Ministerio de Hacienda y Crédito Público (MHCP).

The review was written by Gioia de Melo and Yannic Rehm, with written inputs from and under the supervision of Bert Brys, from the OECD Centre for Tax Policy and Administration. The work benefited from productive meetings with tax officials from DIAN and MHCP, which were held remotely between October 2021 and June 2022.
