The 5-year temporary non-residence rule for UK expats

Key points

• Applies to individuals UK resident for 4 out of 7 tax years prior to leaving.
• The non-residence period must exceed 5 full years to escape the rule.
• Catches gains on assets, shares, and crypto owned before leaving the UK.
• Also applies to certain close company dividends, pension lump sums, and offshore income gains.
• Assets acquired and sold entirely while non-resident are generally exempt.

The temporary non-residence trap explained

A common planning pitfall for British expats moving to zero-tax or low-tax jurisdictions (such as Dubai, Monaco, or the Cayman Islands) is assuming that becoming a non-UK tax resident immediately shields pre-existing assets from UK taxation.

Under Section 279TC and Section 10A of the Taxation of Chargeable Gains Act 1992 (TCGA 1992), if you were UK resident for 4 out of the 7 tax years before departure and your period of non-residence is 5 years or less, gains realised during your overseas stay on assets you owned prior to leaving are brought into charge in the tax year you resume UK tax residence.

Which gains and income are caught?

The TNR rules apply to capital assets owned before departure as well as specific income streams extracted during the non-resident period:

• Shares, securities, and cryptocurrency held before your departure date
• UK or foreign residential and commercial property owned prior to moving
• Distributions and dividends paid by close companies you controlled, paid out of pre-departure profits
• Chargeable event gains on life assurance policies and investment bonds
• Certain lump-sum withdrawals from foreign pension schemes and disguised remuneration loans

What is excluded and how to count the 5-year period

Assets acquired after your departure date and disposed of entirely while non-resident are generally not caught by TNR rules. For example, if you buy shares or crypto with salary earned abroad and sell them before returning, those gains remain outside the scope of UK CGT.

Counting the 5-year period requires precise date modeling. The non-residence period must span more than 5 years (calculated from the date of departure under a split-year case or 6 April of the departure year to the date of arrival or 6 April of the return year). Returning to the UK even a few weeks too early can inadvertently trigger substantial tax liabilities.
