Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what recent estimate she has made of the number of people with non-domiciled tax status who permanently left the UK in each month of 2024.

The Government’s priority is improving the UK’s competitiveness internationally and securing economic growth. The non-dom reforms have been specifically designed to make the UK competitive with a modern, simple tax regime that is also fair. The reforms establish a tax regime for new residents, which is more attractive to new arrivals than the current rules.

The Government published a Tax Information and Impact Note for this policy on 30 October. This can be found here: https://www.gov.uk/government/publications/tax-changes-for-non-uk-domiciled-individuals/reforming-the-taxation-of-non-uk-domiciled-individuals.

There have always been relatively large flows of non-doms in and out of the UK every year. For example. in the latest HMRC statistics for tax year 2022/23, 8,000 non-doms left and 13,000 arrived.

We anticipate that some non-doms ineligible for the new regime will exit the UK in response to the changes. Taking this migration response into account, the OBR expects the non-dom reforms to raise £33.8 billion over the next five years to help fund the public services and investment projects needed to drive growth.
