Moving money from a UK SIPP after settling in France is not governed by the label “25% tax-free cash”. A SIPP, meaning a self-invested personal pension, is a UK pension wrapper, but the French analysis turns on the legal character of the payment, your tax residence and the France–UK tax treaty for the relevant year. A regular flexi-access drawdown, an uncrystallised funds pension lump sum, an annuity and a death benefit must not be treated as interchangeable.

This guide is for a British citizen who is tax resident in France and is taking a payment from a private UK SIPP. It explains how to classify the withdrawal, how the treaty can allocate taxing rights, which French returns and evidence are normally relevant, and what to do when the provider has withheld UK tax. It does not cover transferring a pension to a QROPS, buying French property or setting up a company. Those are separate legal questions. The general framework is also set out in our guide to UK pensions in France after Brexit. The sources and court decisions below were checked on 28 August 2026; the plan rules, tax year and facts of your payment still control the result.

I. How is UK SIPP drawdown taxed in France after Brexit?

A. Is a SIPP payment a pension, a lump sum or investment income under the France–UK treaty?

The first question is not where the SIPP provider is based. It is what the payment legally represents. A SIPP normally holds pension rights in a UK-registered personal pension arrangement. While the money remains invested inside the wrapper, the investor does not usually report each underlying dividend, interest receipt or capital gain as though it were a personal portfolio. When money is paid out, however, the payment must be classified for both UK and French purposes.

For a British resident in France, the possible descriptions include:

• periodic pension income under flexi-access drawdown;
• a single or substantially single pension payment in capital;
• an uncrystallised funds pension lump sum, which may combine a taxable part and a UK-exempt part;
• a lifetime annuity or another form of pension purchased with the pot; or
• a payment on death to a beneficiary, which is not the same question as the member’s own retirement drawdown.

The words used by the provider are useful evidence, but they are not conclusive. Ask for the plan rules, the payment statement, the tax code applied, the date on which benefits were designated for drawdown, and a breakdown between any tax-free element and the taxable element. A provider may call a withdrawal “flexi-access drawdown” even when the customer has selected a large one-off payment. Another provider may issue several payments under one instruction. The dates and legal basis matter.

French domestic law gives a starting point. The current version of Article 158 of the French General Tax Code places pensions and retirement benefits in the pension-income framework, while its paragraph 5(b quinquies) deals separately with retirement benefits paid as capital. The provision distinguishes the part corresponding to certain contributions from the part corresponding to investment products. That distinction is one reason why a SIPP statement should not be reduced to a single net figure.

The French administration also explains that ordinary pensions are generally shown through the pension-income lines and that retirement capital has its own treatment. Its current pensions and retirement guidance says that a retirement benefit paid in capital may be dealt with under the quotient system or, where the conditions are met, the 7.5% flat levy. That information is helpful, but it does not mean that every UK SIPP withdrawal qualifies for that levy. It is a domestic French route subject to conditions and to the treaty.

The treaty question comes next. Article 18 of the 2008 France–UK tax convention, published by Decree no. 2010-20, covers pensions and similar remuneration paid to a resident of a Contracting State for past employment. The operative sentence says: “ne sont imposables que dans cet Etat.” In English, the private pension is taxable only in the State of residence, subject to the public-service exception in Article 19. For a person who is treaty-resident in France and is receiving a private SIPP pension, that normally points towards France as the taxing State. It does not remove the need to prove the facts or to determine whether the payment is within Article 18.

The word “private” must be tested rather than assumed. A SIPP funded by personal contributions or private employment is normally analysed differently from a pension paid directly by a UK government department for past public service. A SIPP may also contain transferred rights from another arrangement. Keep the transfer history and any evidence showing the origin of the rights. If the withdrawal is connected to a public service scheme, Article 19 of the same convention may apply instead. Under that article, pensions paid by a State or public body for services to that body are generally taxable in the paying State, subject to the nationality and residence exception. A British nationality document by itself does not settle that question.

The tax treaty does not turn every SIPP payment into investment income. The fact that the pension pot held shares or funds is not, on its own, a reason to report the withdrawal as a dividend or capital gain. Conversely, the fact that the payment came from a pension wrapper does not automatically establish that every component is an ordinary pension. A provider’s statement describing a payment as “taxable income”, “tax-free pension commencement lump sum”, “UFPLS” or “drawdown” should be matched against the plan rules and the treaty article.

The UK “25% tax-free” concept is particularly easy to misunderstand. A payment exempt from UK income tax under UK domestic rules can still be relevant to the French return if France has the taxing right. The exemption may be respected, recharacterised or neutralised only after the French domestic rules and the convention have been read together. Do not deduct the 25% from the gross amount in France merely because the UK provider called it tax-free. First determine whether the amount is part of a pension capital payment, whether a treaty exemption applies, and whether a French declaration remains required.

The 7.5% French option deserves the same caution. Article 163 bis II of the French General Tax Code provides that “Les prestations de retraite versées sous forme de capital” may, on an express and irrevocable request, be subject to a 7.5% levy that discharges income tax. The same provision requires, among other conditions, that the payment is not split and that the contributions during the build-up period were deductible from taxable income or related to income exempt in the State that had the right to tax it. It also excludes certain French retirement savings plans.

That wording creates three separate tests for a SIPP withdrawal:

1. Is the amount legally a retirement benefit paid in capital rather than periodic drawdown?
2. Was the payment genuinely not fractioned, taking account of the contractual entitlement and the payment history?
3. Can the taxpayer prove the tax treatment of the contributions, including employer contributions, in the relevant State?

A monthly drawdown over a year is not safely presented as a single capital payment simply because the customer gave one instruction. A payment made in two instalments may require an explanation of why the split was imposed by the scheme rather than chosen by the taxpayer. The Court of Appeal of Lyon, 25 August 2020, no. 19LY03464 dealt with a different pension system and cannot be copied mechanically onto a UK SIPP, but it shows why the non-fractioning condition must be examined against the governing rules and the reason for the separate payments.

The practical conclusion is straightforward. A regular SIPP drawdown should be analysed as pension income unless the documents show a different legal form. A one-off capital payment must be tested under the specific capital rules. A payment connected with public service must be tested under Article 19. The correct treaty article is more important than the provider’s informal description.

B. When can the UK still tax the payment, and what evidence proves French residence?

Brexit did not repeal the France–UK tax convention. It changed the wider legal setting in which British citizens move and work, but the allocation of pension taxing rights continues to depend on the convention and the domestic law of each State. The first evidence question is therefore your residence for the year in which the payment was made.

Article 4 B of the French General Tax Code begins its list with the words: “Sont considérées comme ayant leur domicile fiscal en France au sens de l’article 4 A :” It refers, in particular, to the home or principal stay, professional activity and centre of economic interests. It also says that a person meeting one of those domestic criteria is not treated as a French resident where an international tax treaty makes the person resident in the other State. In practice, the French domestic analysis and the treaty tie-breaker must be documented together.

Create a residence file before you ask the provider or HMRC to change the tax treatment. It should normally include:

• the dates on which you lived in France and the United Kingdom during the tax year;
• evidence of the home available to you and where your spouse or dependants lived;
• French tax registration and filed returns, where applicable;
• utility bills, rental documents, property records and other evidence of habitual living in France;
• employment, business or retirement evidence showing where your economic life was centred;
• your French tax residence certificate or other formal correspondence from the tax administration; and
• evidence of UK residence only if you are claiming that the treaty tie-breaker leaves you resident in the United Kingdom or that a split-year issue changes the result.

The evidence must correspond to the year of payment. A French residence card may prove immigration status, but it is not by itself conclusive proof of treaty residence. Conversely, a UK correspondence address does not establish UK treaty residence if your home, family and economic interests had moved to France.

The Conseil d’État judgment of 14 February 1979, no. 06961 remains a useful warning about proof. In that older France–UK case, the court held that British nationality and receipt of a pension from the British Crown did not, without probative documents about residence for UK income tax, establish UK treaty residence. The decision concerned an earlier convention and different facts; it is not a SIPP ruling. Its evidential lesson remains relevant: nationality, a pension and a bank account do not replace residence documents.

If the SIPP is a private pension and Article 18 applies, the usual treaty position is that the pension is taxable only in the State where the recipient is resident. If the pension is a qualifying public-service pension, Article 19 may allocate the taxing right to the United Kingdom, subject to its exception. If the payment is not a pension under the treaty, another article may need to be considered. Do not claim a foreign tax credit before identifying the article that permits it.

Article 24 of the convention sets out the elimination-of-double-taxation method. It distinguishes income taxable in the United Kingdom from income for which France grants a credit when the United Kingdom has taxed the same item in accordance with the convention. The method is not a general licence to subtract any UK PAYE from French tax. A UK deduction that was made contrary to Article 18 may need to be reclaimed from HMRC rather than credited in France. A payment that is properly taxable in both States under a different provision may require a different calculation. The gross payment, tax withheld and treaty article must be shown separately.

The treaty also contains a practical procedure for disagreement. Article 26 allows a resident who considers that measures taken by one or both States produce taxation contrary to the convention to submit the case to the competent authority, independently of domestic remedies. It identifies time limits linked to the first notification and the end of the relevant tax year. That procedure is not a substitute for a timely French tax claim or an HMRC repayment request. It is an escalation route when the two administrations disagree about residence, classification or relief.

There is a second distinction that prevents many errors: pension income is not the same as an overseas account-reporting obligation. Article 1649 A of the French General Tax Code requires a person domiciled or established in France to declare “les références des comptes ouverts, détenus, utilisés ou clos à l’étranger” at the same time as the income return. A UK SIPP is a pension arrangement, not automatically an ordinary current or savings account. Its reporting status must be assessed by reference to the arrangement and the applicable form instructions.

Do not make either of the two opposite mistakes. Do not declare a SIPP as an ordinary bank account without checking what the form covers. Do not assume that the wrapper means no foreign-account analysis is ever required. Obtain a provider description of the legal product, its administrator, its cash account and any linked investment account. If a separate UK bank account receives the drawdown, that account must be considered on its own facts. This avoids both under-reporting and duplicating the same asset.

II. How do you declare, correct or challenge UK SIPP tax in France?

A. Which French return, boxes and documents should a British resident use?

The safest filing method is to work from the gross annual payment and then follow the form instructions for the treaty result. The current Form 2047 page on impots.gouv.fr says that the form is used when a person domiciled in France has received income outside metropolitan France and the overseas departments, and that it is attached to the general income return. A UK SIPP payment received by a French tax resident should therefore be reviewed for Form 2047 treatment even where the treaty ultimately gives France a credit or the United Kingdom exclusive taxing rights.

The filing sequence is normally:

1. identify the payer, the country, the gross amount and the date of each payment;
2. convert the sterling amount into euros using the method applicable to the French return for the relevant year, keeping the rate and calculation;
3. describe the payment in the appropriate section of Form 2047 and identify the treaty treatment;
4. carry the amount to the corresponding category on Form 2042 or Form 2042-C, where the instructions require a transfer;
5. report any UK tax actually and finally borne only in the place provided for the applicable credit mechanism; and
6. retain the SIPP statement, provider correspondence, tax certificate, exchange-rate record and proof of residence.

The precise line can change with the tax year and with the treaty treatment. A regular foreign pension taxable in France may be carried to the pension lines on the general return. A foreign pension giving a treaty credit may be reported through the lines that identify the credit mechanism. A capital payment for which the French 7.5% option is valid belongs in the capital-pension lines, not simply in the ordinary pension line. The French tax administration’s pension guidance refers to the ordinary pension lines 1AS or 1BS and to lines 1AT or 1BT for a capital pension subject to the 7.5% option. Check the form for the year being filed, because old screenshots and old tax guides can contain obsolete numbers.

The domestic filing rule is broader than the final tax calculation. Article 170 of the French General Tax Code, in its version in force from 21 February 2026, states that “toute personne imposable audit impôt est tenue de souscrire” a detailed income declaration. It also requires the declaration to include items that a convention exempts but that must be considered for other elements of the tax calculation. That is why “the UK did not tax it” or “the treaty gives a credit” is not a reason to leave a foreign pension unexplained.

The French public information service follows the same practical logic. Its guidance on declaring retirement pensions explains that retirement pensions must be declared, that some amounts are exempt, and that retirement paid in capital has its own options. The page was checked on 15 April 2026. It is not a substitute for reading the France–UK convention, but it is a useful check against relying on a UK-only tax label.

Use a reconciliation sheet with one row per payment. A simple format is:

Item	What to record	Why it matters
Payment date	Actual date funds were made available	Determines the tax year and can affect the claim deadline
Gross sterling	Amount before PAYE or provider deductions	Prevents a net payment being reported as the taxable base
UK tax	PAYE withheld and whether it is final	Separates an improper withholding from a treaty credit
French classification	Periodic pension, capital, annuity or other	Determines the return section and domestic rules
Treaty article	Article 18, Article 19 or another tested provision	Identifies the State with the taxing right
Exchange rate	Rate, date and calculation used	Makes the euro figure auditable

Consider a purely illustrative example. A French-resident taxpayer receives four monthly SIPP drawdown payments of £2,000. The provider withholds £400 in total during the year. The taxpayer should not enter £7,600 as the French pension simply because that is the bank credit. The starting figure is the gross £8,000, converted under the applicable method. The £400 is then analysed: if Article 18 gives France the exclusive right to tax, the taxpayer may need to seek repayment or correction in the United Kingdom. If another treaty provision permits a credit, the credit is calculated under that provision and the French instructions. The answer cannot be produced from the net transfer alone.

For a single capital withdrawal, add the contractual history. Record whether the payment was one transfer, whether it followed a crystallisation event, whether a tax-free component was identified, whether the provider split it into separate tranches, and how contributions were treated when made. If the 7.5% option is being considered, keep documents proving the contribution deduction or exemption condition. The option is express and irrevocable, so do not tick a box merely because it produces a lower estimate.

The 7.5% calculation is not simply 7.5% of the bank credit. Under Article 163 bis II, the levy is based on the capital after the statutory 10% allowance, subject to the conditions in the article. The impots.gouv.fr explanation also states that the amount before deductions is entered in the relevant capital line and that a pre-filled ordinary pension amount may need to be corrected. A UK SIPP’s own breakdown must be mapped onto those French concepts; the provider does not complete the French return for you.

Social contributions require a separate check. French income tax, the prélèvements sociaux (social contributions), health cover and the treaty are related but not identical questions. A person with an S1, meaning a portable healthcare entitlement document, may have a different social-contribution analysis from a person covered through French employment or another basis. Do not infer the social contribution result from the income-tax article alone. Keep evidence of healthcare affiliation and follow the current Form 2047 and French guidance for the year.

The account question should be recorded separately as well. If the pension provider maintains a cash account, an investment account or a linked bank account, identify each legal product and its holder. The declaration of a foreign account, where required, does not replace the declaration of pension income. Equally, a pension-income line does not automatically satisfy Article 1649 A. The forms serve different purposes.

The final pre-submission check should ask:

• Have you reported the gross amount rather than the net bank credit?
• Have you used the form instructions for the exact tax year?
• Have you identified whether the payment is periodic or capital?
• Have you tested Article 18 against the public-service exception in Article 19?
• Have you recorded UK withholding separately from the treaty allocation?
• Have you avoided reporting the same amount twice through both a pre-filled line and Form 2047?
• Have you considered a separate Article 1649 A analysis for linked foreign accounts?

B. What can you do if tax was withheld, the 7.5% option was missed or the tax office reassesses you?

Start with the source of the error. A UK provider can withhold tax because its records still show a UK address, because it has not received a residence certificate, because its PAYE code is temporary, or because the payment was treated as taxable under UK domestic rules before treaty relief was requested. The withholding does not prove that the United Kingdom has the final taxing right.

Ask the provider for a written payment breakdown and a copy of the information sent to HMRC. Check the address, residence status, tax code, gross payment, tax-free component and payment type. If the plan administrator can correct future payments, ask what evidence it requires and when the new treatment takes effect. For past payments, gather the annual pension statement and the proof of French treaty residence needed for the HMRC repayment or treaty-relief process. Keep a copy of every form and message, including the date of submission.

The claim to HMRC and the French filing should tell the same factual story. If the French return describes the amount as a private pension taxable only in France, the HMRC request should not describe it as a government pension. If the payment was capital in France, the documents should explain why it is not being presented as four ordinary monthly pensions. Inconsistencies invite delay and can undermine an otherwise valid claim.

If France has assessed too much tax, use the secure messaging service or the competent French tax office to preserve a written record, then make a formal réclamation (tax claim) where necessary. State the tax year, assessment reference, amount challenged, legal basis, calculation, requested correction and supporting documents. Attach the SIPP statement, the treaty analysis, proof of residence, Form 2047/2042 copies, UK tax evidence and the exchange-rate calculation.

The ordinary time limit matters. Article R*196-1 of the French Book of Tax Procedures, in force from 30 July 2026, provides that most claims must be filed by 31 December of the second year following the relevant assessment, payment or event, with special rules for certain withholding disputes. Work from the actual assessment and payment dates rather than from the date you first discovered the mistake.

The Conseil d’État judgment of 14 June 2017, no. 397052 concerned a capital retirement payment and the 7.5% option. The court held that the request “peut être formée par le contribuable par voie de réclamation” up to the Article R*196-1 claim deadline, even though the benefit had not been requested in the original return, subject to the statutory conditions. This is not a ruling that every SIPP drawdown qualifies. It is a procedural safeguard for an eligible capital payment when the taxpayer can still prove the substantive requirements.

That decision should not be used to turn periodic drawdown into capital after the event. The claimant must still establish the payment’s legal nature, non-fractioning and contribution history. The decision also does not extend the deadline automatically. It is a reason to check the claim route promptly, not a reason to postpone filing.

If the administration treats a private SIPP as a different category of income, answer the reassessment in stages:

1. identify the exact payment that has been reassessed;
2. show the plan rules and provider description;
3. explain why the payment is or is not a pension, capital benefit or public-service pension;
4. apply the relevant treaty article to the documented facts;
5. recalculate the French base in euros and show any credit separately;
6. address social contributions as a distinct issue; and
7. make the procedural request within the claim deadline.

Do not answer a French information request with a single annual bank statement. A bank statement proves the amount credited, not the gross payment, the legal nature of the benefit, the UK tax withheld or the treaty residence. Supply the provider’s annual statement and the correspondence that explains the payment.

Where the dispute concerns residence, a residence certificate can be important but may not answer every factual issue. The administration may ask where the family lived, where the home was available, where work was carried out and where the economic centre was located. The older Conseil d’État decision no. 06961 illustrates why a pension and nationality alone are weak evidence. Assemble a dated chronology and attach independent documents.

Where the dispute concerns an apparent double tax, distinguish three outcomes:

Situation	Likely first action	Evidence to attach
Private SIPP, treaty-resident in France, UK PAYE withheld	Declare the gross amount in France and seek UK correction or repayment if Article 18 gives France exclusive taxing rights	French residence evidence, provider statement, PAYE record and treaty analysis
Public-service pension or mixed rights	Separate the public and private components before claiming relief	Service history, scheme rules, transfer records and payment breakdown
Eligible single capital payment, 7.5% option omitted	Check a French réclamation before the Article R*196-1 deadline	One-payment evidence, contribution tax treatment and original return
UK and France both tax under a provision allowing relief	Apply the Article 24 credit method rather than treating all UK tax as deductible	Final UK tax evidence and French computation
Unclear residence or treaty interpretation	Use domestic claims first and consider the Article 26 mutual-agreement route	Chronology, notices, residence documents and copies of prior claims

Article 26 of the France–UK convention is the mutual-agreement procedure. It can be relevant when the two tax administrations do not agree on residence or treaty classification, and it may be submitted independently of domestic remedies. The convention sets a three-year period after the first notification of the measure that creates non-conforming taxation, and a separate six-year reference to the end of the relevant tax year or assessment period. Those treaty periods do not remove the need to protect the shorter domestic deadlines.

The UK side also has its own practical distinctions. GOV.UK’s guidance on tax when you live abroad explains that the tax treatment of a pension paid abroad can depend on the country and the applicable tax treaty. GOV.UK’s page on transferring a pension to an overseas pension scheme is relevant to transfers, not to ordinary drawdown, which is why a withdrawal should not be presented as a QROPS transfer. The UK government’s France country guidance on tax, benefits and pensions is another useful starting point for the UK administrative side, but it does not replace the treaty text or French return instructions.

The current UK material also illustrates why the payment category must be fixed before advice is requested. HMRC’s Employment Income Manual guidance on dependent, nominee and successor drawdown, updated in August 2026, concerns pension benefits paid after a member’s death; it is not a rule for the member’s own retirement drawdown. The current HS345 pension tax-charge guidance likewise demonstrates that UK tax treatment can turn on the type and timing of the benefit. These updates are useful warning signals, not a replacement for the France–UK allocation of taxing rights.

If the provider refuses to amend the withholding, request the refusal in writing. If HMRC rejects a repayment, retain the decision and reasons. If France refuses the treaty treatment, retain the assessment and response. A later appeal is much easier when the file shows the original documents, the precise question asked, the answer received and the calculation that follows.

Before sending any correction, check five dates: the payment date, the date the UK tax was withheld, the French return deadline, the date of the French assessment and the last date for a French réclamation. Then check five figures: gross sterling, UK tax, euro conversion, French taxable amount and any credit. A table that reconciles those dates and figures often exposes a double declaration or a missing component before the administration does.

The legal strategy is therefore evidence-led. A SIPP withdrawal is not solved by choosing the most favourable label. It is solved by proving residence, identifying the payment, applying the correct treaty article, filing the gross amount through the correct French route and challenging an incorrect withholding or assessment within time.

Conclusion

For a British citizen who is treaty-resident in France, a private UK SIPP drawdown will often require a French pension-income analysis under Article 18 of the France–UK convention. That conclusion is not automatic: public-service rights, transferred benefits, capital withdrawals, split payments and death benefits can change the legal route. The UK 25% tax-free label does not by itself determine the French result, and a UK PAYE deduction does not by itself create a French tax credit.

The practical sequence is to obtain the complete SIPP and payment records, prove residence for the payment year, classify each payment as periodic income or capital, identify the treaty article, complete Form 2047 and the relevant French return, and separate pension reporting from any foreign-account obligation. If tax was withheld in the wrong State, seek correction from the responsible administration and preserve a French réclamation before the applicable deadline. If an eligible capital option was missed, check the Article 163 bis conditions and the Article R*196-1 time limit rather than abandoning the claim.
