The trap that changed in April 2026
There's a set of rules called the temporary non-residence rules, and they exist specifically to stop people using a short stint abroad to strip value out of a UK company tax-free before coming home. Until this year, they had a significant carve-out.
If you left the UK, your company kept trading, and it built up profits after you'd gone, dividends paid from those post-departure profits generally escaped the temporary non-residence charge even if you came back within five years. Only dividends linked to profits earned before you left were at real risk. It was a genuine planning window, and for a lot of contractors and small business owners doing a two or three year posting abroad, it was one of the practical reasons a UK Ltd company still made sense.
From 6 April 2026, that carve-out is gone. HMRC's own policy paper on the change is blunt about the intent: this measure removes the concept of post-departure trade profits from the temporary non-residence rules, so that all distributions from a close company received while you're temporarily non-resident are now chargeable to UK income tax when you return, whatever period they relate to.
In practice, that means a director who leaves the UK, keeps the company trading, draws dividends abroad for two or three years, then comes home, is now taxed on the full amount in the year of return. Not just the pre-departure slice. All of it. One illustration used by tax advisers describes someone drawing £200,000 in dividends while abroad and returning within five years: under the old rules a meaningful chunk of that could have been shielded as post-departure profit; under the new rules, the whole £200,000 is taxed on return.
The "temporary" in temporary non-residence has a specific meaning, and it's stricter than most people assume. You need to have been UK resident in at least four of the seven tax years before you left, and you need to stay non-resident for more than five complete tax years to fall outside the rules entirely. Depending on exactly when you leave and whether split-year treatment applies, that can mean planning your departure and return dates with genuine precision, sometimes needing a buffer of several months rather than cutting it fine on a single day, specifically so there's no argument later about which side of the line you fell on.
For anyone treating a period abroad as a genuine, open-ended relocation rather than a temporary posting, this is less pressing; once you're clear of the five-year window, none of it applies. It's the two, three or four-year plan that has quietly become riskier, because the old escape route for dividends earned during that period has closed.
The three real options, and what each one actually costs you
Once the tax position is clear, business owners we work with tend to land on one of three structures.
Keep the UK Ltd running as is. This remains the simplest option administratively, and for a business that genuinely needs a UK presence, a UK VAT number, or UK-based contracts, it may still be the right one. What's changed is that you now need to plan dividend timing and the length of your absence with the temporary non-residence rules explicitly in mind, rather than treating them as background noise. If there's any realistic chance of returning to the UK within five years, dividends drawn while you're away need modelling before they're paid, not after.
Make the company dormant and operate through a new structure overseas. For business owners whose work has genuinely relocated with them, and where the UK entity was really only ever a vehicle for UK-based trading, this is often cleaner. It avoids the ongoing UK filing burden and removes the temporary non-residence question for future income entirely, though it doesn't retrospectively fix anything already extracted from the old structure.
Set up a genuinely overseas entity from the outset. This suits business owners building something new once they're already settled abroad, particularly where the client base, banking, and day-to-day operations are all local to the new country. The trade-off is usually banking friction and reduced familiarity with a UK client base that may still prefer dealing with a UK-registered supplier.
There's no single right answer here, and anyone telling you there is hasn't looked closely enough at your actual circumstances. What all three options share is that they need deciding before you leave, not worked out retrospectively once HMRC has a view on what you did.
