Managing your money after leaving the UK

What changes about your money when you leave the UK?

In one line: your worldwide exposure to UK tax shrinks to your UK-source exposure. Once you're non-resident — or from your split date if you leave mid-year — the UK stops taxing your foreign income and most of your foreign gains. What it does not stop is tax on money with a UK root, plus National Insurance and the 5-year rule, which run on their own clocks.

Three principles run through everything below:

1. Residence decides the worldwide charge; source decides the UK charge. Non-residence takes your foreign income out of UK tax — never your UK-source income (UK rent, UK workdays, UK pensions, gains on UK land).
2. Income tax and National Insurance are different regimes with different tests. One can stop while the other keeps running.
3. A short absence is not a safe harbour. Leave for five years or less after being UK-resident in 4 of the prior 7 years and the temporary-non-residence rule can claw back income and gains in your year of return (HMRC HS278, 2026).

What stops, and what doesn't? (the one-table answer)

Why do income tax and National Insurance part ways?

Direct answer: Because they're decided by different tests. Becoming non-resident for income tax takes your foreign earnings out of UK income tax — but it does not automatically end your UK National Insurance. Income tax follows residence; NIC follows where you work and who employs you.

• NIC keeps running if a UK employer sends you abroad temporarily — the 52-week rule keeps you on UK Class 1 for the first 52 weeks.
• NIC keeps running where you hold a certificate of coverage (the EU/EEA version is the A1/PDA1).
• NIC can keep running for directors of UK companies — a directorship is an office, not switched off by emigrating.

Can you stay a director of your UK company after you leave?

Direct answer: Yes — but a directorship is the strand with the most threads still attached. Three issues to hold separately:

1. Your dividends are UK-source. Dividends from your own UK company are UK-source even when you're abroad. As a non-resident they're usually disregarded income (the tax is capped), but they never become "foreign".
2. UK board duties create UK workdays — and a tie. Every day you do >3 hours' work in the UK, including a board meeting, counts towards the 40-day work tie and is UK-source income.
3. Company residence is a separate, harder question. Where your company's "central management and control" sits can make the company UK-resident regardless of where you live — high-stakes, get advice.

What happens to UK dividends and savings interest?

Direct answer: UK dividends and most UK savings interest are "disregarded income" for non-residents: your UK tax on them is capped at the tax deducted at source — now usually nil — but only if you forgo the personal allowance against your other UK income. HMRC works it out both ways and you pay the lower (HMRC HS300, 2026; SAIM1170).

Who keeps the £12,570 allowance: as a non-resident you get it only if you're a British citizen, an EEA national, a Crown employee, or where a treaty grants it. Movers to the UAE keep it via citizenship, not the UK–UAE treaty. See UK dividends and savings when non-resident.

Do you still pay UK tax on UK rental income — the Non-Resident Landlord Scheme?

Direct answer: Yes. UK rental income is always UK-taxable, however long you're away — it is not disregarded income. Under the NRLS your letting agent (or tenant) must deduct 20% tax from the rent and pay it to HMRC, unless HMRC approves you to receive it gross via form NRL1 (gov.uk NRLS; PIM4810).

NRL1 approval does not make the rent tax-free — it only moves collection from withholding-at-source to Self Assessment. Either way the rental profit is taxed; either way you file a return for it (and renting out UK property is itself a reason you'll be in Self Assessment for the departure year). See UK rental income when living abroad.

What about capital gains — is everything free except UK property?

Direct answer: Broadly, yes. Once non-resident you're outside UK CGT on most assets — shares, funds, foreign property. The big exception is UK land and property: gains stay within UK CGT (NRCGT), and you must report the disposal within 60 days of completion even if there's no tax to pay (gov.uk CGT for non-residents).

• In scope: UK residential property (gains since 6 April 2015) and all UK land plus certain indirect disposals (since 6 April 2019).
• The 60-day report is mandatory regardless of outcome — even with no tax due or a loss.
• Rebasing means you generally pay only on the gain since the asset came into the regime (5 April 2015 / 5 April 2019).
• You keep the £3,000 annual exempt amount (2026/27, frozen) as a non-resident.

See capital gains tax for non-residents.

The 5-year trap — why coming back too soon undoes it

Direct answer: Leave for five years or less after being UK-resident in 4 of the 7 years before you went, and the temporary-non-residence rule drags certain income and gains you "banked" while away back into UK tax — in your year of return (HMRC HS278, 2026). A clean break means staying non-resident more than five full tax years.

Assets you acquire after you leave are generally outside the charge. And split-year treatment is not a safe harbour — the overseas part still counts towards the temporary-non-residence period. See the temporary non-residence rule.

What happens to your ISAs and UK pensions?

Direct answer: Your ISA stays open and keeps its UK tax-free status while you're abroad, but you can't pay new money in once you stop being UK-resident. For UK pensions, you can keep getting tax relief as a "relevant UK individual" — up to £3,600 gross with no UK earnings — but that status is generally lost after five complete tax years of non-residence (gov.uk; PTM044100).

• ISAs: existing accounts stay open and tax-free and can be transferred; you can't subscribe new money once non-resident (unless a Crown employee overseas or their spouse). Tell your ISA provider when you leave.
• Pensions: a non-earner abroad can contribute up to £3,600 gross (pay £2,880 net, HMRC adds £720) and still get relief, until five complete tax years of non-residence have passed.

Your pre-departure money checklist

1. Confirm you'll actually be non-resident. Run the SRT for the departure year and the year after — start with the residence status calculator.
2. Work out your split date. Check whether split-year treatment applies and when your year divides.
3. Decide how you'll tell HMRC. A P85 if you're not in Self Assessment; the SA109 if you are. Not both.
4. Sort your National Insurance. Will it keep running? Pay voluntary Class 3 to protect your State Pension? Apply on CF83.
5. Set up your UK rental. The NRLS kicks in — decide whether to apply on NRL1 for gross rent, and brief your agent.
6. Plan disposals around the 5-year clock. UK property triggers the 60-day report whenever you sell; other assets are safe from clawback only after five full tax years away.
7. Tell your ISA provider; check your pension status.
8. Keep a UK account or nominee for any refund, and keep your travel records and filing copies.
9. Flag the high-stakes calls for an adviser — company management and control, dual residence and the treaty tie-breaker, large gains, trusts and IHT.
