Moving Back to the UK: The Financial Checklist Expats Forget

There’s plenty of advice and support for people moving abroad, but not much for those coming back.

But returning home can have just as big an impact on your finances, and mistakes are often costly and difficult to fix. For example, you might lose a year’s tax relief by coming back at the wrong time, face unexpected charges on a pension transfer, convert your savings when rates are poor, or find your estate is taxed again when you thought it was safe.

The good news is that careful planning can make a big difference when you return. Starting in 2025, there’s also a new, time-limited benefit for Britons coming back that wasn’t available before.

Here’s a checklist to go through before you land.

Time your return — the date matters more than you'd think

The Statutory Residence Test, not the day you sign a lease, decides when you become a UK tax resident again. It is a good idea to read our guide to the Statutory Residence Test before making any plans, because the tax year you become a resident affects everything else.

Two rules are especially important. Split-year treatment means you may be taxed as a non-resident for the part of the year before you return, and as a resident after you come back. This can really affect you if you have income or gains to manage before or after your move.

Because so much hinges on the tax year of your return, the timing of your arrival — even by a few weeks around 5 April — can make a big difference to your situation.

The returning-Brit advantage: four tax-free years

This change has made a big difference for people coming back. Since 6 April 2025, anyone who becomes a UK tax resident after at least 10 consecutive tax years of non-residence can claim the Foreign Income and Gains (FIG) regime.

The FIG regime lets you claim full UK tax relief on your foreign income and gains for your first four tax years back. You can bring this money into the UK and spend it without any extra charges.

Importantly, nationality and domicile do not matter here. This rule is based on residence, so returning Brits qualify, even though they were mostly excluded from the old non-dom rules. If you’ve been away for ten years or more, you could have four years where foreign investment income or gains from selling an overseas home or business can come back to the UK tax-free.

However, it rewards planning, and it isn't a free lunch:

• You must claim it each year on your Self Assessment return. It’s never automatic.

• If you claim, you lose your UK personal allowance and your capital gains annual exemption for that year. For small amounts, this could cost you more than you save.

• The four years start as soon as you arrive and cannot be paused. If you have a large foreign gain, it’s best to realise it within this window, as it can be very valuable.

The main point is this: if you’ve been away for ten years or more and have foreign income or gains to bring back, get advice on timing and planning before you move, not after.

The flip side: short absences get caught

If you haven’t been away long, the rules are different. Under the temporary non-residence rule, if you were a UK resident before leaving and return after a short time abroad (usually five years or less), some income and gains made while away can be taxed when you return, as if you had never left. This rule stops people from briefly moving abroad just to avoid tax on a gain.

So, how long you’ve been away makes a big difference. If you’ve been gone for over a decade, you could get four tax-free years. A short absence can mean your time abroad is still taxed in the UK. Make sure you know which rules apply to you.

Your pensions

Becoming a UK resident again changes how your pensions are treated, so check the status of any overseas pension, international SIPP, or QROPS before you move.

One thing to watch out for: if you transferred a UK pension to a QROPS and then return to the UK within five years of that transfer, you might face a charge you thought you’d avoided, applied retrospectively. This is just one of the traps we cover in transferring a UK pension overseas. If you moved your pension recently, make sure to consider your return date.

Your investments and ISAs

You can’t contribute to an ISA while you’re non-resident. But once you’re a UK resident again, your annual allowance is available, and you can start paying in. Read our article on your ISA and moving abroad to get the full picture.

Beyond ISAs, review any offshore holdings and think about when to realise gains. If you qualify for the FIG regime, you can shelter a large foreign gain during your four-year window. If you’re caught by temporary non-residence, the opposite is true. This is definitely an area where you should get advice on timing.

Your property and your money

If you’re selling an overseas home, the timing of your sale and any FIG claim can make a difference. A gain realised in the right year may be sheltered.

When you bring the proceeds home, you’ll need to think about currency. Will the exchange rate on the day mean you lose money when you convert to sterling? It’s worth planning ahead instead of leaving it to chance. See our articles on the cost of moving money and managing currency exposure to learn more.

Your estate

There are two things to review. First, update your will to make sure it’s valid and effective for your UK return and any assets you still hold overseas.

Second, remember that becoming a UK resident again gradually brings your worldwide estate back under UK inheritance tax. Once you’ve been resident for 10 of the previous 20 tax years, you become a ‘long-term resident ’, and your global assets are included. We explain more in our article on UK inheritance tax for expats.

The admin nobody warns you about

When you move back to the UK after time abroad, paperwork can take weeks to sort out:

• Your UK credit history: Years abroad can leave you looking like a financial ‘ghost’ to UK lenders, with no recent footprint. This makes it harder to get mortgages, credit cards, or even mobile contracts. Rebuilding your credit takes time, so start early.

• Banking: Some accounts are closed or restricted for non-residents, so you may need to re-open or set up UK banking when you return.

• The NHS: You’ll usually need to re-register with a GP and re-establish ordinary residence to get free NHS care.

• National Insurance and your State Pension: Check your NI record for any gaps from your years away, and get a State Pension forecast. Your time abroad may have left gaps worth addressing.

The checklist, in order

Before moving back to the UK, go through the following steps:

1. Confirm your residence position and the best tax year to return (Statutory Residence Test, split-year).

2. Check whether you qualify for the four-year FIG regime — and plan when to realise foreign income and gains.

3. If you've been away only briefly, check the temporary non-residence rule.

4. Review overseas pensions, SIPPs and any QROPS — mind the five-year transfer tail.

5. Plan the timing of realising investment gains, and know when your ISA reactivates.

6. Plan overseas property sales, the currency conversion, and any UK purchase.

7. Restart the admin early: credit history, banking, NHS, NI and State Pension.

8. Refresh your will and note the inheritance-tail on your estate.

A smooth transition

You don't need to feel overwhelmed. Thousands of expats return to the UK smoothly every year. Planning ahead helps when you still have more options, rather than after, when some choices may no longer be available.
