This is the fifth edition of Corporate Tax Statistics, an annual publication that brings together information on corporate taxation and base erosion and profit shifting (BEPS) practices that previously were unavailable to tax policy researchers and policymakers. This includes data on corporate tax rates, revenues, effective tax rates (ETR), tax incentives for research and development (R&D) and innovation, and withholding taxes amongst other data series. Corporate Tax Statistics also includes anonymised and aggregated Country-by-Country Report (CbCR) data providing an overview on the global tax and economic activities of thousands of multinational enterprise groups operating worldwide. Corporate Tax Statistics follows on from the OECD/G20 BEPS Project and its package of fifteen measures adopted in 2015 to address tax avoidance. The project’s Action 11 noted that the lack of available and high-quality data on corporate taxation is a major limitation to the measurement and monitoring of the scale of BEPS and the impact of the measures agreed to be implemented under the OECD/G20 BEPS Project.
