- You cannot transfer a SIPP directly into an ISA — UK rules don't allow it for anyone, resident or not
- The usual UK workaround is to withdraw from the SIPP and pay the money into an ISA instead — but as a French resident, you're not allowed to open or pay into a UK ISA at all
- Withdrawing from your SIPP will trigger a French taxable event, whether or not you go on to reinvest anywhere
- If you want a wrapper for the money once it's out, a French assurance vie is the realistic option — not a UK ISA
You cannot transfer funds directly between a SIPP and an ISA, UK-resident or not. If you are now resident in France and you want to reinvest your SIPP into something else, the UK workaround to withdraw from the SIPP and pay the proceeds into an ISA instead is not possible.
For the fuller picture on how SIPPs and ISAs are each taxed once you're in France, see our guide to ISAs and SIPPs: How France Treats Them.
Why There's No Direct SIPP-to-ISA Transfer
A SIPP and an ISA are two completely different types of account under UK law, and HMRC treats them accordingly:
- A SIPP is a pension wrapper — money goes in with tax relief, and in exchange it's locked away until at least age 55 (rising to 57 from 2028).
- An ISA is a savings wrapper with no such lock — you can take money out whenever you like, but you never got tax relief going in.
You can transfer from one SIPP to another — that's routine. You cannot transfer from a SIPP to an ISA. The only way money moves between them is the long way round: take the money out of one, then pay it into the other as a fresh contribution.
Being a French resident changes everything about that second step.
Can I open an ISA as a French Resident?
No. The UK ISA providers only accept new contributions from people who are UK tax resident in that tax year. Once you become a French tax resident, that door closes — the only exception is for Crown employees working overseas and their spouses or civil partners.
This means the standard "withdraw from SIPP, pay into ISA" route as a UK resident simply isn't available to you. Any UK ISA you already hold from before your move can stay open and keep its existing funds — though those funds are now taxable as a French resident — you just can't add to it.
If you're already paying into a UK ISA and haven't told your provider you've moved to France, this is worth sorting out. Continuing to contribute as a French resident isn't permitted under UK rules, and any contributions made after your move may need to be unwound.
What Happens if I withdraw from my SIPP in France?
Taking money out of your SIPP is a genuine French tax event — France taxes the withdrawal itself.
Regular drawdown is declared as pension income on Form 2047, Line 12, carried to Form 2042, Box 1AM or 1BM. France applies an automatic 10% deduction before calculating what you owe, then taxes the rest at your normal progressive income tax rates, plus social charges unless you hold an S1. For the full mechanics of this — including how an S1 changes what you owe — see our UK Private Pension guide.
Taking the whole pot as a single lump sum can qualify for a flat 7.5% rate instead (under Article 163 bis of the French tax code) — but only if it's genuinely a one-off withdrawal of the entire pension, your scheme qualifies under French rules, and you made no tax-deductible pension contributions while living in France. Full detail on how this works, including the worked calculation, is in our Pension Lump Sums guide.
While the SIPP sits untouched, growth inside it isn't taxed in France at all. The tax only arrives when you actually draw money out.
So What Can You Actually Do With the Money?
Once SIPP funds are withdrawn and taxed, they're just cash — you can do whatever you like with them, including reinvest in a French account. The question is which wrapper, if any, makes sense once a UK ISA is off the table.
The realistic option most UK expats in France end up looking at is a French assurance vie. It isn't a substitute for the ISA in the way it works — different rules, different tax treatment — but it plays a similar role as a long-term, tax-advantaged savings wrapper, with its own favourable rates after eight years. Read our full guide to assurance vie withdrawals and social charges.
A PEA (Plan d'Épargne en Actions) is another French-resident-only option if the money is going into shares or funds — see our PEA guide for eligibility and how it compares.
Working out what a SIPP withdrawal actually costs you in French tax — before you decide whether it's even worth doing — means running the numbers on income tax and social charges together. Taxpert's French Tax Bill Estimator shows both side by side, so you can see the real cost before you touch the pension.
Where This Usually Goes Wrong
The mistake isn't really about ISAs and SIPPs specifically — it's assuming that because both accounts are "tax-free" in the UK, moving between them stays tax-neutral wherever you happen to live. Once you're a French resident, neither half of that assumption holds. The SIPP withdrawal is taxable in France the moment it happens, and the ISA isn't available to non-UK residents. Readers who start this process expecting a like-for-like internal transfer are often surprised twice: once by the tax bill, and again when their ISA provider rejects the contribution outright.
Common Mistakes on SIPP-to-ISA Transfers
-
Assuming "transfer" means something similar to a pension-to-pension transfer. SIPP-to-SIPP transfers between providers are routine and don't trigger tax. A SIPP-to-ISA move is not a transfer at all — it's a withdrawal followed by a separate contribution, with tax consequences at the withdrawal stage.
-
Not realising French residency blocks the ISA side entirely. This isn't a French tax rule — it's a UK ISA eligibility rule. But it means the workaround most guides describe simply doesn't apply to you.
-
Withdrawing from a SIPP without checking the French tax cost first. Whether you use progressive income tax or the 7.5% lump-sum route, the amount due can be substantial. Work this out before withdrawing.
-
Continuing to pay into an existing UK ISA after becoming French resident. If you had an ISA before moving and kept contributing out of habit, those contributions aren't permitted and may need to be reversed.
-
Assuming an assurance vie works exactly like an ISA. It's a genuinely different product with its own rules, its own tax treatment, and its own timing considerations (particularly around the eight-year mark). Treat it as its own decision, not a straight swap.
Frequently Asked Questions
Can I transfer a SIPP directly into an ISA if I'm still a UK resident?
No — this isn't possible for anyone, regardless of residency. A SIPP and an ISA are different account types under UK law, and there is no direct transfer mechanism between them. You would need to withdraw from the SIPP and separately contribute to the ISA, subject to your annual ISA allowance.
I'm a French resident with an existing UK ISA from before I moved. Can I still add to it?
No. UK ISA providers only accept contributions from UK tax residents, with a narrow exception for Crown employees working overseas. You can keep an existing ISA open and its current funds remain UK tax-free, but you cannot pay in any further money as a French resident.
Does withdrawing from my SIPP count as capital or income in France?
Income. Regular SIPP drawdown is declared as pension income on Form 2047 Line 12 and Form 2042 Box 1AM/1BM — not on any capital gains form. A qualifying full lump-sum withdrawal is taxed differently, at a flat 7.5% rate after allowance, but it's still a pension-income event, not a capital one.
If I can't put SIPP proceeds into an ISA, is there a French equivalent?
Not a direct equivalent, but a French assurance vie serves a similar long-term savings role, with its own tax advantages that build up over time — particularly after eight years. It works differently to an ISA, so it's worth understanding on its own terms rather than assuming the two are interchangeable.
Will I be taxed twice — once by the UK and once by France — on my SIPP withdrawal?
Under Article 17 of the UK-France tax treaty, private pension income including SIPP drawdown is taxable only in France once you're a French resident. Tell HMRC you've become a French resident so UK tax isn't deducted at source. If it is deducted in error, declare the full gross amount in France and reclaim the UK tax from HMRC directly.
