Corporate Tax Statistics: Third Edition


Published 29 July 2021




The Corporate Tax Statistics database is intended to assist in the study of corporate tax policy and expand the quality and range of data available for the analysis of base erosion and profit shifting (BEPS).

The 2015 Action 11 report, Measuring and Monitoring BEPS, highlighted that the lack of quality data on corporate taxation is a major limitation to the measurement and monitoring of the scale of BEPS and the impact of the OECD/G20 BEPS project. While this database is of interest to policy makers from the perspective of BEPS, its scope is much broader. Apart from BEPS, corporate tax systems are important more generally in terms of the revenue that they raise and the incentives for investment and innovation that they create. The Corporate Tax Statistics database brings together a range of valuable information to support the analysis of corporate taxation, in general, and of BEPS, in particular.

The database compiles new data items and statistics currently collected and stored by the OECD in various existing datasets. The third edition of the database contains eight main categories of data:

  • corporate tax revenues
  • statutory corporate income tax rates
  • action 13 implementation
  • anonymised and aggregated Country-by-Country Report statistics
  • forward-looking effective tax rates
  • tax incentives related to R&D and intellectual property regimes
  • controlled foreign company rules
  • interest limitation rules


Understanding the database

The data on statutory corporate tax rates for OECD jurisdictions are sourced from the OECD Tax Database. An explanatory annex for OECD jurisdictions and an explanatory annex for non-OECD jurisdictions contain further information on statutory corporate income taxes for certain jurisdictions.

The methodology for calculating the ETRs is described in detail in the OECD Taxation Working Paper, Corporate Effective Tax Rates: Model Description and Results from 36 OECD and Non-OECD Countries, building on the theoretical model developed by Devereux and Griffith (1999, 2003). Further methodological information is available in the corporate effective tax rates explanatory annex.

The data on coporate tax revenues are sourced from the Global Revenue Statistics DatabaseRead the technical paper on the construction of the Global Revenues Statistics Database: its coverage, sources, strengths and limitations. The database follows the definition of tax in the OECD classification of taxes and Interpretative Guide.

BEPS Action 13 is part of the transparency pillar of the OECD/G20 BEPS project, supporting jurisdictions in combating BEPS. The database contains information on the domestic legal frameworks for Country-by-Country reporting around the world.

Anonymised and aggregated CbCR statistics represent an important new source of data on the global tax and economic activities of multinational enterprises. The statistics are subject to a number of important data limitations, detailed in the disclaimer.

The database contain two sets of indicators that offer a complementary view of the extent of R&D tax support provided through expenditure-based R&D tax incentives. The first set focuses on synthetic tax policy indicators that capture the effect of expenditure-based R&D tax incentives on firms’ investment costs. It contains two new indicators of the effective average tax rate for R&D and the cost of capital for R&D. These indicators are produced by the Centre for Tax Policy and Administration and the OECD Directorate for Science, Technology and Innovation. The methodology is outlined in an accompanying OECD Taxation Working Paper, Corporate Effective Tax Rates for R&D. Further modelling notes are available in an explanatory annex. It complements estimates of implied tax subsidy rates based on the B-Index indicator sourced from the OECD R&D tax incentives database produced by the OECD Directorate for Science, Technology and Innovation. The second set of indicators, sourced from the OECD R&D tax incentives database, display the cost of expenditure-based tax incentives to the government together with estimates of direct government support to business R&D.

The data on IP regimes are compiled from information collected by the Forum on Harmful Tax Practices for its peer reviews of preferential regimes.

Data on CFC rules are available for 49 jurisdictions for the year 2019.

Data on interest limitation rules are available for 67 jurisdictions for the year 2019.
