Moving back to France after years in the UK: close one country properly, reopen the other
The return move is the one nobody prepares for — you assume you know your own country. Then comes the reverse admin shock: a Sécu that no longer knows you, a tax residence that flips mid-year, a UK pension you could quietly keep building for pennies. Here’s the move home, done properly.
You’ve lived in the UK for years — studies, career, a whole chapter — and you’re moving back to France: alone, as a couple, maybe with children born on the other side. You want to leave nothing valuable behind (pension rights, tax positions) and rebuild the French side without the runaround.
- Closing the UK is an active step, not a formality: tell HMRC you’re leaving (form P85 or your final Self Assessment) so your final tax year is split and overpaid tax comes back to you.
- Your UK State Pension keeps building if you want it to: voluntary National Insurance contributions (Class 2 if you work in France — a few pounds a week) are one of the best deals in European retirement planning. Ten qualifying years minimum unlock a UK pension for life.
- Your ISA loses its magic at the border: France doesn’t recognise the wrapper, so gains and interest become taxable like any account. Decide what to do BEFORE you become French tax resident.
- French healthcare doesn’t restart by itself: re-register with the CPAM (immediately through an employer, or after 3 months of stable residence via PUMa) and reactivate your carte Vitale — then add a mutuelle.
- Your belongings come home duty-free (12+ months abroad, goods owned 6+ months, inventory required) — but the paperwork must be done at the border crossing, not after.
Closing the UK properly — the steps that pay you back
Leaving the UK well is mostly about four letters: HMRC. Tell them you’re going — via form P85 (with your P45 from your last employer) or, if you file Self Assessment, through your final return with the residence pages. Two good things follow: your leaving year is treated under split-year rules (UK tax stops applying to your post-departure income), and because PAYE assumed you’d work a full year, there’s very often an income tax refund waiting. People routinely leave hundreds of pounds unclaimed here.
The rest of the exit checklist is unglamorous but each line has a cost attached: give proper notice on the tenancy and document the hand-back (your deposit is protected — reclaim it), close the council tax account (refunds for overpaid months are real), cancel the TV licence (pro-rata refund), redirect mail, and keep your P45s, P60s and payslips — they’re the evidence base for both your UK pension record and any treaty questions later.
Taxes: the mid-year flip, without double paying
From the day you settle in France, you’re generally French tax resident — and taxable in France on worldwide income from that date. The UK taxes you up to departure. The France–UK tax treaty arbitrates everything that overlaps: UK rental income stays taxable in the UK (France accounts for it via a credit mechanism), private pensions shift to France, government pensions stay in the UK, and so on.
Concretely, your first French spring is the milestone: you’ll file your first income declaration covering the months since arrival. There’s no tax at source running for you yet on foreign income, so anticipate the cash-flow: the first bill can arrive as a lump. The official « Je reviens en France » pages on impots.gouv.fr are genuinely good; for anything with income on both sides in the same year, a cross-border accountant for one season is money well spent. And once employed in France, rediscover your payslip with our net salary guide — after years of UK gross-to-net, the French line items are a culture shock of their own.
Your UK pension: the cheapest retirement asset you own
This is the section that pays for the guide. The UK State Pension works on qualifying years of National Insurance: 10 years minimum to get anything, 35 for the full amount. If you leave with, say, 8 years, you’re 2 years from a pension for life — and you don’t need to work in the UK to finish the job.
Voluntary NI contributions let you keep adding years from France. If you work abroad (employed or self-employed) you’ll usually qualify for Class 2 — currently a few pounds per week, roughly £180 per year, for a year that adds hundreds of pounds per year to your future pension, for life. Even at Class 3 rates (~£900/year) the arithmetic is usually excellent. Check your record and forecast on your personal tax account, confirm your class with HMRC (form CF83), and set up the payments before the habit fades.
Your workplace pensions stay put and get claimed from France later (see FAQ), and your French retirement doesn’t lose the UK years either: post-Brexit coordination preserves totalisation between the two systems. The one thing that destroys value here is amnesia — keep the records, keep the access, diarise the forecast check once a year.
Money: banks, the ISA trap, and moving the savings
French banking first: you’ll need a French account and its RIB for salary, CPAM, utilities — everything. If a branch is sluggish about a returning resident with no French history, remember the droit au compte and the practical routes; online banks are usually the fastest door back in.
The ISA needs a decision before you move. Its tax-free status is a UK fiction that France doesn’t share: once French resident, interest, dividends and gains inside an ISA are taxable in France like any ordinary account (and investment funds can fall under unfriendly reporting rules). Options people actually use: realise gains while still UK resident (they’re tax-free up to that point), keep it and accept French taxation on the income, or redeploy into French wrappers — assurance-vie being the closest cultural equivalent. Which is right depends on amounts and horizon; deciding before the residence flip is the part that’s universally right.
Transfers: for the big one-off move of savings, a multi-currency service (Wise and similar) at mid-market rates beats high-street bank spreads by a wide margin. Don’t move everything on day one — the GBP/EUR rate becomes part of your decision, and a UK account left open gives you the luxury of choosing your moment.
Healthcare: waking up the Sécu
Your rights don’t resume by themselves. The route back: if you start a job, your employer’s declaration re-opens your rights essentially immediately; otherwise, PUMa covers any stable resident after 3 months of residence. Either way, contact the CPAM of your new département with proof of address and civil status, reactivate (or re-request) your carte Vitale, declare a médecin traitant — the gateway to full reimbursement rates — and add a mutuelle, because the Sécu reimburses well but not fully. The full mechanics (PUMa, carte Vitale, mutuelle, sector 1 vs 2) are in our French healthcare guide.
Mind the gap: between leaving NHS coverage and your first French rights, carry travel/expat health cover for the interval — a three-month uninsured window with a family is a risk nobody should take to save €100.
The practical layer: licence, customs, children
Driving licence. If you passed your test in the UK (or exchanged into a UK licence), you can generally keep driving in France on it for a transition period, then exchange it via ANTS — conditions, deadlines and the post-Brexit specifics are exactly the subject of our licence exchange guide. Don’t let it expire first: an expired foreign licence usually can’t be exchanged, and that means retaking a French test.
Your belongings. Post-Brexit, a UK→France move is an import from a third country — but returning residents get a full customs franchise: no duties or VAT on household goods, provided you’ve lived outside the EU for at least 12 months, owned the goods for 6+ months, and present a detailed inventory (dated, valued, signed) plus proof of your UK residence at the crossing. Your remover handles the forms if you brief them early; a car can come under the same relief (then needs French registration). The one unforgivable error: doing the paperwork “later” — the franchise is claimed at the border, not retroactively.
Children raised in the English system slot back in by birth year, with UPE2A support if their written French lags their spoken French — the full mechanics (carte scolaire, mairie enrolment, keeping their English at native level through sections internationales) are in our schools-in-France guide. And if the return city is Paris and the neighbourhood question is open, choose it with data — your instincts may be eight years old.
The first-year sequence
Before departure: P85/final return · deposit + council tax closure · NI record check + CF83 · ISA decision · inventory for customs · visa file if your partner isn’t European. First month: address → bank/RIB → CPAM re-registration → médecin traitant + mutuelle → school enrolment at the mairie. First year: first French tax declaration in spring · licence exchange within its window · voluntary NI standing order · pension forecast check. Three fronts, each with deadlines that don’t remind you — which is precisely what a living roadmap is for.
FAQ
I’m French — surely coming home is simple?
Administratively, you’re treated as a newcomer in several systems: your CPAM file has usually gone dormant, your bank may have closed or downgraded your account, and every counter wants a French proof of address you don’t have yet. None of it is hard; all of it is sequenced. The difference from a foreigner’s move is that nobody warns you — hence this guide.
My partner is British — what do they need?
Post-Brexit, a British partner moving to France needs a long-stay visa and then a residence permit, like any non-EU national — being married or PACSed to a French citizen opens the “vie privée et familiale” route, which is favourable but not automatic. Start the visa file before the move; our residence permit guide covers the mechanics.
Do my UK years count for my French retirement?
Yes — the post-Brexit coordination between the UK and the EU preserves totalisation: your UK years are taken into account so that neither pension system penalises the split career. In practice you’ll claim two pensions (one from each country, each paying for its own years). Keep every P60 and NI record; future-you will thank you.
What happens to my UK workplace pension?
It stays invested in the UK and you claim it from France at retirement age — nothing forces a transfer. Under the France–UK tax treaty, private and workplace pensions are generally taxed in France once you’re resident (government-service pensions stay UK-taxed). Transfers to non-UK schemes (QROPS) exist but are a niche, fee-heavy decision — take regulated advice before touching one.
Should I keep a UK bank account?
If your bank allows it, yes — it makes UK pension payments, old subscriptions and any UK income vastly easier to handle. Since Brexit, some UK banks have closed accounts held by EU residents, so ask the question explicitly. If you lose it, a multi-currency account (Wise and similar) fills most of the gap for transfers at honest exchange rates.
