The global minimum corporate tax rate proposed by the OECD is one step closer to implementation following the publication of model rules on 20 December 2021. 

These “global anti-base erosion” or “GloBE” rules are the main component of Pillar Two of the OECD’s BEPS 2.0 project, and aim to ensure that large multinational enterprise (MNE) groups pay a minimum effective tax rate (ETR) of at least 15% on their profits in every jurisdiction in which they operate.

The rules, which reflect an unprecedented degree of co-ordination between countries on corporate tax, are a major milestone and put countries in a position to push ahead with domestic implementation of the proposals, which the OECD envisages will take effect from 2023.

This hub page will provide updates on BEPS 2.0 and pull together a collection of our thought leadership on international tax reform.
