Details

The UK and more than 135 other countries agreed, as part of the OECD Inclusive Framework, to a two-pillar solution to reform the international corporate tax framework in response to the challenges of digitalisation.

Pillar 2 of this solution, known as the Global Base Erosion (GloBE) rules, requires a group with consolidated annual revenues of more than €750 million to pay a minimum 15% tax on its profits in each jurisdiction it operates in.

As part of the UK adoption of these rules, the government announced 2 new taxes that will apply to accounting periods starting on or after 31 December 2023:

  • the Multinational Top-up Tax (MTT)
  • Domestic Top-up Tax (DTT)

This information will help you prepare for the new rules.
