The Full Form of DEPS is‍ Base erosion and profit shifting.

Base erosion and profit shifting (BEPS) refers to tax planning strategies used by multinational enterprises that exploit gaps and mismatches in tax rules to avoid paying tax. Developing countries’ higher reliance on corporate income tax means they suffer from BEPS disproportionately. BEPS practices cost countries USD 100-240 billion in lost revenue annually. Working together within OECD/G20 Inclusive Framework on BEPS, over 135 countries and jurisdictions are collaborating on the implementation of 15 measures to tackle tax avoidance, improve the coherence of international tax rules and ensure a more transparent tax environment.
