Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what recent assessment he has made of the potential impact of changes to the taxation of Non-Domiciled taxpayers on taxes received.

The Government is committed to addressing unfairness in the tax system, so that everyone who makes their home in the UK pays their taxes here.

That is why the Government removed the outdated concept of domicile status from the tax system from April 2025 and replaced it with a new internationally competitive residence-based regime, focused on attracting the best talent and investment to the UK.

The OBR certified at Autumn Budget 2026 that the reforms are expected to raise £39.5bn by 2030-31. Further detail on the approach to costing the reforms was published by the OBR in January 2025, and is available here: https://obr.uk/docs/dlm_uploads/Non-doms-supplementary-release-Jan-2025.pdf

HMRC will continue to monitor the impacts of the reforms as they do in all cases.
