The OECD/G20 Inclusive Framework released a package of technical and administrative guidance that achieves clarity on the global minimum tax on multinational corporations known as Pillar Two. Further, it provides critical protections for important tax incentives, including green tax credit incentives established in the Inflation Reduction Act. Pillar Two provides for a global minimum tax on the earnings of large multinational businesses, leveling the playing field for U.S. businesses and ending the race to the bottom in corporate income tax rates. This package follows the release of the Model Rules in December 2021, Commentary in March 2022 and rules for a transitional safe harbor in December 2022. The guidance will be incorporated into a revised version of the Commentary that will replace the prior version.

Additionally, the package includes guidance on over two dozen topics, addressing those issues that Inclusive Framework members identified are most pressing. This includes topics relating to the scope of companies that will be subject to the Global Anti-Base Erosion (GloBE) Rules and transition rules that will apply in the initial years that the global minimum tax applies. Additionally, it includes guidance on Qualified Domestic Minimum Top-up Taxes (QDMTTs) that countries may choose to adopt.

“The continued progress in implementing the globalminimum tax represents another step in leveling the playing field for U.S. businesses, while also protecting U.S. workers and middle-class families by ending the race to the bottom in corporate tax rates,” said Assistant Secretary of the Treasury for Tax Policy Lily Batchelder. “We welcome this agreed guidance on key technical questions, which will deliver certainty for green energy tax incentives, support coordinated outcomes and provide additional clarity that stakeholders have asked for.”
