International tax advisor for UK leavers: what to look for (and what it costs)

Zero Tax · Updated July 2026 · 8 min read

A London consultant moved to Dubai in June, kept his flat "just in case", flew back for client meetings twice a month and sold his company shares in November, confident he was gone. The statutory residence test disagreed: too many ties, too many days. HMRC taxed the whole year, gain included. Leaving the UK is not an address change. It is a test you either pass or fail, and the exam questions were published in advance.

Why UK exits got serious after 2025

The abolition of the non-dom regime in April 2025 turned the UK into a worldwide-taxation country for anyone resident, full stop. The replacement FIG regime helps arrivals (4 years of relief on foreign income and gains for new residents), not leavers. For those heading out, three mechanisms decide everything:

The window closing in April 2028: if you ever used the remittance basis as a non-dom, the Temporary Repatriation Facility lets you designate pre-April 2025 foreign income and gains and bring them onshore at 12% (designations in 2025/26 and 2026/27) rising to 15% in 2027/28, with designations closing 5 April 2028. Against alternative rates up to 45%, this is the cheapest clean-up most former non-doms will ever be offered. Leavers often forget the TRF applies to them too: designating before you go can be the difference between a tidy exit and a frozen offshore pot.

What a good advisor for UK leavers actually does

1. Models your SRT position before you move

Counts your realistic UK days, maps your ties, and tells you which band you must stay within, including the anti-avoidance day-counting traps (deeming rules, transit days, exceptional circumstances).

2. Sequences the exit year

Split-year eligibility, the right order for leaving employment, starting work abroad, disposing of the home, and the timing of dividends and bonuses so they fall on the right side of the line.

3. Plans disposals around the five-year rule

If a company sale or large gain is coming, the calendar of your non-residence has to cover it with margin. This single decision often dwarfs everything else in the plan.

4. Coordinates the destination

UAE, Portugal, Italy, Cyprus, Singapore: each pairs differently with UK-source income you keep (rent, dividends, pensions) via the relevant treaty, withholding rules and the destination regime. UK rental income stays UK-taxable; UK dividends generally become treaty business.

5. Handles what stays behind

The UK company you still own, ATED and non-resident landlord registration for property, national insurance, pension access from abroad, and inheritance tax: after the 2025 reforms IHT follows long-term residence rather than domicile, and long-term UK residents remain in scope for years after leaving (a tail worth mapping precisely for your dates).

Red flags when choosing your advisor

Frequently asked questions

Does the UK have an exit tax?

No general exit tax, but the temporary non-residence rules tax gains realized during absences shorter than 5 years upon return, which works like a deferred one.

What is the TRF and when does it end?

A flat 12% (2025/26, 2026/27) or 15% (2027/28) rate to designate and repatriate pre-April 2025 foreign income and gains of former remittance-basis users. Designations close 5 April 2028.

How many UK days can I keep after leaving?

Between 16 and 182 depending on your ties under the SRT. Model it before committing to a travel pattern.

How much does a UK exit plan cost?

London firms bill hundreds per hour and five figures per plan. Zero Tax: $449 USD for the strategy consultation with a written signed opinion.
