HMRC Letters – UK adoption of OECD Pillar 2 model rules

HMRC are currently undertaking a second Pillar 2 communications campaign aimed at businesses that may be in scope of the new Domestic Top-up Tax (DTT) and Multinational Top-up Tax (MTT), or both. The letters are educational in nature and are recommending that the businesses assess how these taxes may affect them and prepare for their implementation in December 2023. The letter includes:

• Details on the new online service
• An update on legislation and guidance
• Frequently asked questions

Letters will be sent to two populations of businesses. A copy of each letter is provided below.

• Large Business (LB) customers signed up by their Customer Compliance Manager (CCM)
• Wealthy and Mid Sized Business Compliance (WMBC) customers that have signed up to receive email updates. This includes agents/representative bodies who have also signed up.

These letters follow an initial campaign in June 2023 which we also publicised on our website – see here.
