Who the rule catches
The rule bites where two conditions are both met. First, you had sole UK residence for at least 4 of the 7 tax years immediately before the year you left, which puts longstanding UK residents firmly in scope while genuine newcomers usually escape. Second, your period of non-residence is 5 years or less. To be safe you need to be away for more than 5 years, meaning a minimum of 5 years plus one day, and the period is measured using Statutory Residence Test and split-year dates, not calendar years. A departure and return that look like five clear years on a calendar can still fall inside the window once the correct residence-period dates are applied.
What gets taxed when you come back
Caught amounts are treated as arising in the tax year you return and taxed then, at that year's rates and allowances. The main categories are chargeable gains on assets you owned before you left and sold during your absence, distributions and dividends from close companies where you were a material participator, certain pension payments and lump sums, chargeable event gains on life policies, offshore income gains and written-off loans to participators. There is one important exclusion: gains on assets you both acquired and disposed of entirely during the absence are generally not caught, subject to limited anti-avoidance exceptions. The tax is reported through Self Assessment for the year of return, as our full guide to returning to the UK explains.
The 2026 change and why timing is everything
From 6 April 2026 the rules were widened for owner-managers. Previously, dividends attributable to profits your company earned after you left the UK sat outside the charge. For individuals returning on or after 6 April 2026 that carve-out is gone, so the full amount of a close-company distribution received while temporarily non-resident can be brought into UK income tax in the return year, with relief only for any foreign tax actually paid on it. For someone in a zero-tax jurisdiction there may be no foreign tax to credit, so the UK charge can be the full liability. The reliable escape routes are to stay away for more than 5 years or to structure disposals so they fall outside the caught categories, and both have to be planned before you leave the UK, not on the way home.
