Domestic tax base erosion and profit shifting (BEPS) due to multinational enterprises exploiting gaps and mismatches between different countries' tax systems affects all countries. Developing countries' higher reliance on corporate income tax means they suffer from BEPS disproportionately.

Business operates internationally, so governments must act together to tackle BEPS and restore trust in domestic and international tax systems. BEPS practices cost countries 100-240 billion USD in lost revenue annually, which is the equivalent to 4-10% of the global corporate income tax revenue.

Working together in the OECD/G20 Inclusive Framework on BEPS, over 135 countries are implementing 15 Actions to tackle tax avoidance, improve the coherence of international tax rules and ensure a more transparent tax environment.
