The UK government is considering a major policy shift that could impact high-net-worth individuals planning to leave the country. A proposed 20% exit tax is being explored, targeting wealthy individuals who relocate their tax residency. This potential tax could be implemented as early as 26 November 2025.
For high-net-worth individuals, particularly those with non-domiciled status, understanding this proposal is crucial for future financial planning. Here are the main points to consider, with a more detailed analysis available from our legal partners at RHJ Law.
What is the proposed exit tax?
An exit tax is a charge governments levy on individuals or companies when they move their tax residency or assets to another country. The goal is to capture tax revenue on wealth accumulated within the country before it is moved abroad. The new UK proposal suggests a 20% tax on the capital gains an individual has acquired while residing in the UK, even if those gains are only realised after they leave.
Who would be affected?
The proposed tax is aimed at wealthy non-domiciled individuals, who reside in the UK but consider their permanent home to be in another country. These individuals often hold substantial global assets and currently benefit from the UK’s remittance basis of taxation. If implemented, the tax would impact those relocating to low-tax jurisdictions and anyone who has built up wealth in assets while living in the UK.
Why is this being proposed?
The primary driver is the UK’s need to strengthen public finances. This tax is projected to generate an estimated £2 billion in annual revenue, which could be used to fund public services. Another factor is the growing international pressure for fairer tax systems, ensuring that wealthy individuals who have prospered within the UK’s economy contribute their share before they relocate.
How does this compare to global standards?
Exit taxes are not a new concept. Several other developed nations, including the United States, Canada, and France, have similar measures to protect their tax base. The UK’s proposal would align it with this broader global trend of governments ensuring that departing wealthy residents pay their share of tax on gains accrued during their residency.
Navigating your next steps
This proposed exit tax highlights a growing trend of governments tightening tax rules for mobile high-net-worth individuals. As public finances come under pressure, measures like exit taxes may become more common, making strategic planning more important than ever.
If you are a high-net-worth individual in the UK considering a move, it is vital to stay informed and plan ahead. For a more in-depth breakdown of the legal implications check out the latest updates on the RHJ Law website.
