Key Takeaways
What you'll learn in this article
  • The FIG regime replaced the old non-dom remittance basis from 6 April 2025 and is based on residence, not domicile.
  • Qualifying new arrivers can claim 100% relief on foreign income and gains for their first four years of UK residence.
  • To qualify you must have been non-UK-resident for the ten consecutive tax years before you arrive.
  • For a long-serving Gulf expat with overseas investments, four tax-free years on foreign income and gains can be very valuable, but it must be claimed.
  • The clock and the ten-year rule make the timing of your return, and how long you've already been away, central to the planning.

For decades, the question "how will the UK tax my overseas wealth when I move back?" was answered by the old non-domicile rules. From 6 April 2025 those rules were abolished and replaced by the Foreign Income and Gains (FIG) regime — and for a long-serving Gulf expat, the new system can hand you four tax-free years on your foreign income and gains. This guide explains who qualifies and why it pays to understand it before you book the move. To map your return, see the returning-to-the-UK planner.

From domicile to residence

The headline change is conceptual. The old regime hinged on domicile — a slippery, inherited concept that could keep someone "non-dom" for years. The FIG regime throws that out and uses residence, which is far more objective: it's about where you've actually lived, decided by the Statutory Residence Test.

Under FIG, someone who becomes UK resident and meets the qualifying condition can elect for 100% relief on their foreign income and gains for their first four years of UK residence. During those four years, qualifying foreign investment income, foreign dividends, and foreign capital gains can escape UK tax.

The ten-year rule

Here's the gateway: to qualify, you must have been non-UK-resident for the ten consecutive tax years immediately before the year you arrive.

For many Gulf expats this is good news — a decade in Dubai, Doha or Riyadh often clears the bar comfortably. But it cuts both ways:

  • If you've been away ten years or more, you likely qualify for the full four-year window.
  • If you've been away only a few years, you don't qualify yet — and returning now means your overseas income and gains are taxed normally from day one.

That single condition can make the difference between a return that's tax-efficient and one that isn't, which is why your residence history is one of the first things to pin down.

Why the four-year window is a planning opportunity

Four years of relief on foreign income and gains is not just a passive perk — it's a window to act in. If you have:

  • overseas investments sitting on large unrealised gains,
  • foreign dividend income, or
  • assets you intend to sell anyway,

then realising or restructuring them during the four-year FIG window can be dramatically more efficient than doing it in year five, when worldwide taxation resumes. The relief is time-limited, so the value comes from planning which income and gains land inside the window.

The catches

  • It must be claimed. FIG relief is elected through Self Assessment — it doesn't happen automatically.
  • There are trade-offs. Claiming can affect your personal allowance, so it's not always worthwhile for every slice of income.
  • It's only foreign income and gains. UK-source income is taxed normally throughout.

Where it fits

Frequently Asked Questions
What is the FIG regime?
The Foreign Income and Gains regime is the UK system that replaced the non-domicile remittance basis from 6 April 2025. Instead of depending on domicile, it depends on residence. Qualifying individuals in their first four years of UK residence can elect for 100% relief on their foreign income and gains, rather than being taxed on them in the UK.
Who qualifies for the four-year FIG regime?
Broadly, someone becoming UK resident who has been non-UK-resident for the ten consecutive tax years immediately before arriving. If you meet that test, you can claim FIG relief for up to your first four years of UK residence. Many long-serving Gulf expats meet the ten-year condition, but you should confirm your exact residence history.
How long does FIG relief last?
Up to the first four tax years of UK residence, provided you qualified on arrival. After the four years, you are taxed on your worldwide income and gains in the normal way. Because it is time-limited, planning which income and gains to realise during the four-year window is where much of the value sits.
Do I have to claim the FIG regime?
Yes. FIG relief is not automatic. It is claimed through Self Assessment and there can be trade-offs, such as the effect on your personal allowance, so it is not always the right choice for every type of income. Take advice on whether and how to claim it for your circumstances.
