- A UK policy maturing doesn't come with UK tax rules attached once you're a French resident — France taxes the gain under its own rules, not the UK's chargeable-event framework
- Whether the payout is taxed as investment income or under the Assurance Vie regime depends on how the specific policy is legally structured, not on what it's called
- The 5% UK "tax-deferred withdrawal" allowance and UK top-slicing relief don't exist in French tax law — they're irrelevant to your French declaration
- Once the payout is taxed and in your account, leaving it in cash isn't your only option — a PEA or an assurance vie are both worth comparing before you decide
A UK endowment policy or investment bond maturing feels like good news — the plan worked, the money's arrived. What catches people out is assuming the tax treatment travels with it. It doesn't. Once you're a French tax resident, France taxes the payout under its own rules, on its own terms, regardless of what HMRC would have done with the same policy.
For how ISAs and SIPPs — the other common UK products — are treated once you're in France, see our guide to ISAs and SIPPs: How France Treats Them.
The First Question: What Kind of Policy Is It?
This matters more than the payout amount, because it decides which set of French rules apply.
You moved to France, left a UK endowment policy or investment bond exactly where it was, and it's now coming up for maturity. An ordinary UK endowment or investment bond like this has no French assurance vie status — France doesn't apply the assurance vie regime to it at all. Instead, it treats the gain as ordinary investment income (revenus de capitaux mobiliers), the same category as interest and dividends. This is the scenario the rest of this article covers.
There's one exception worth ruling out first. If, since moving, you deliberately restructured that money into a policy legally built to sit inside the French assurance vie wrapper — even one administered by a UK or Irish provider, like Prudential International — it's taxed under the assurance vie regime instead. That means the gain (not the full payout) is taxed at a flat rate that depends on the policy's age, with an annual allowance available once the policy has run for more than 8 years. If that's your situation, we've covered it in detail, with a real worked example from an actual Prudential statement, in Do You Pay Social Charges? Assurance Vie Withdrawals — that article walks through the exact calculation.
If you're not sure which applies to your policy, that's worth confirming with the provider or a financial adviser before you file — the difference in tax treatment, and the paperwork you need, isn't small.
How the Payout Is Actually Taxed in France
UK investment bonds have their own domestic mechanics which is not recognised under French tax law.
France re-categorises the gain under its own domestic rules and taxes it accordingly — as investment income, under the standard flat tax.
The gain — the difference between what you paid in and what the policy pays out — is taxed as investment income under the PFU (prélèvement forfaitaire unique, the flat tax), the same regime that applies to bank interest and dividends. For a fuller explanation of how the PFU works and when the alternative progressive-scale option might be cheaper, see our guide to PFU vs Progressive Tax.
Without an S1, the combined rate is 31.4% for 2026 — 12.8% income tax plus 18.6% social charges.
With an S1, the social charges portion drops to the reduced 7.5% solidarity levy in place of 18.6%, for a combined rate of 20.3%. An S1 means you're affiliated to the UK's social security system rather than France's — see our S1 explained guide if you're not sure whether you hold one.
Declaring it: the gain is declared on Form 2047, under foreign investment income, then carried to Form 2042, Box 2TR (or the dividend-equivalent box if the policy is structured as an equity-linked payout rather than interest-type growth — check with your provider which applies). The account itself must also be declared annually on Form 3916, the same requirement that applies to any foreign account, with a penalty of €1,500 per account per year for missing it — including the year it matures and closes.
Working out exactly which French box a foreign payout belongs in, and converting it to euros at the right rate, is exactly the kind of thing that's easy to get wrong on a one-off event like this.

The Money Is Taxed — Now What?
Once the payout has been declared and taxed, it's just cash sitting in your account — and leaving it there isn't a great long-term option. Bank interest is taxed the same way every year it sits, and inflation quietly erodes it while it earns close to nothing.
Two French-resident-only wrappers are worth comparing before you decide where it goes next:
A PEA (Plan d'Épargne en Actions) offers income tax exemption on gains after 5 years, with only social charges (18.6%, or 7.5% with an S1) still due. It's capped at €150,000 in contributions and restricted to European shares and eligible funds, but it doesn't degrade with age the way assurance vie's succession benefit does. Full detail on eligibility, providers, and how the tax treatment works is in our complete PEA guide — including which funds currently qualify, an area worth keeping an eye on given ongoing government debate over ETF eligibility rules.
A French assurance vie is the other realistic option, particularly if succession planning matters to you — premiums paid before age 70 carry a generous inheritance allowance that a PEA doesn't replicate. See our guide to SIPPs vs Assurance Vie for how the two compare, including the succession angle.
Neither is a like-for-like replacement for what you had in the UK — both are genuinely French products with their own rules, and which one (or combination) fits depends on your age, timeline, and whether succession planning is part of the decision.
The Catch
Expecting tax to be due isn't the mistake. The mistake is assuming the UK's own tax mechanics — the 5% allowance, top-slicing relief, the chargeable-event calculation — still apply once you're filing in France. They don't. France doesn't recognise any of those UK-specific reliefs — it recalculates the gain from scratch under its own domestic categories, which can mean a materially different tax bill than a UK-resident holder of the identical policy would have paid.
Common Mistakes on a Maturing UK Policy
-
Assuming the payout is capital, not income. The gain portion is taxed as income (investment income or assurance vie gain, depending on structure) — not as a capital receipt exempt from tax.
-
Applying UK top-slicing relief or the 5% deferred allowance to the French calculation. Neither exists in French tax law. They're UK-only mechanisms and have no bearing on what you owe in France.
-
Not checking whether the policy is legally an assurance vie. The tax treatment, allowance, and declaration route differ significantly depending on this, and it isn't always obvious from the policy's name alone.
-
Forgetting Form 3916 in the year the account closes. The account still existed for part of the year — the declaration is still required, even though it won't exist next year.
-
Leaving the payout sitting in cash indefinitely. Once it's taxed, cash in a bank account is one of the least tax-efficient places to leave a lump sum in France — it's worth actively comparing a PEA or assurance vie rather than defaulting to inertia.
Frequently Asked Questions
Is a UK endowment policy maturity payout tax-free in France?
No. Once you're a French tax resident, the gain on a maturing UK policy is taxable in France, regardless of any tax-free treatment it might have had in the UK. The specific rate and declaration route depend on whether the policy is structured as a genuine assurance vie or an ordinary investment bond.
Does the UK's 5% tax-deferred withdrawal allowance apply to my French tax return?
No. That allowance is a UK-specific mechanism with no equivalent in French tax law. France taxes the gain under its own rules and ignores UK deferral or top-slicing relief entirely.
How do I know if my policy counts as an assurance vie for French tax purposes?
This depends on the policy's legal structure, not its name or provider. Some UK and Irish providers, like Prudential International, offer products specifically built to qualify as assurance vie contracts for French residents. If you're not sure, ask your provider directly or check with a financial adviser before filing.
What rate applies if I don't hold an S1?
The combined rate for 2026 is 31.4% — 12.8% income tax plus 18.6% social charges — applied to the gain, not the full payout amount.
Where should I put the money once it's taxed?
There's no single right answer — it depends on your age, timeline, and whether succession planning matters to you. A PEA and a French assurance vie are the two main French-resident-only options worth comparing, each with different tax treatment and different strengths.
