New Pillar Two regulations

The Multinational Top-up Tax (Pillar Two Territories, Qualifying Domestic Top-up Taxes and Accredited Qualifying Domestic Top-up Taxes) (Amendment) Regulations 2025 have now been laid, and come into force later this week on 24 July 2025. The regulations enable HMRC to specify additions to the list of Pillar Two territories, qualifying domestic top-up taxes, and accredited qualifying domestic top-up taxes to take effect from a date before the notice is published.

According to HMRC, this is a procedural change to ensure the effective date of changes in the UK aligns with the date in the central record of internationally agreed qualifying territories and taxes published by the OECD/G20 Inclusive Framework. It also means that there will be no requirement for individual Statutory Instruments which would otherwise be required due to the retrospective nature of such changes.

Employer PAYE liability disputes

HMRC is currently developing an online form which will enable employers to report disputes on their pay as you earn (PAYE) liabilities.

Currently, employers can either call the Employer Helpline on 0300 200 3200, or write to HMRC at the following address:

PT Operations North East England,
HM Revenue and Customs,
BX9 1BX,
United Kingdom.

Further information will be provided in due course.
