Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what estimate she has made of the revenue raised as a result of the OECD Pillar 2 measures in each of the next five years.

The UK’s implementation of the Multinational Top-up Tax and Domestic Top-up Tax was scored at Autumn Statement 2022, and updated Spring Budget 2023 in ‘table 4.2’. This can be found on gov.uk at https://www.gov.uk/government/publications/spring-budget-2023.

The UK’s implementation of the Undertaxed Profits Rule was scored at Autumn Statement 2023, and updated at Autumn Budget 2024 in ‘table 5.2’. This can be found on gov.uk at https://www.gov.uk/government/publications/autumn-budget-2024.

Taken together, the latest estimate is that all three rules will raise more than £15bn over the upcoming scorecard period.
