Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what additional funding will be required by (a) his Department and (b) the OECD to ensure monitoring and compliance with the proposed Pillar 2 rules of BEPS 2.0.

At Autumn Statement 2022, the Government set out that Pillar 2 will raise £2.3 billion a year by 2027-28.

An estimate of HMRC operational costs to implement Pillar 2 was published in a tax information and impact note in July 2022. This can be accessed on GOV.UK at https://www.gov.uk/government/publications/introduction-of-the-new-multinational-top-up-tax/multinational-top-up-tax-uk-adoption-of-organisation-for-economic-co-operation-and-development-pillar-2

The Government will publish an updated tax information and impact note at the Spring Budget.
