Receiving a UK State Pension in France should not normally mean paying the same income tax twice. Yet a British resident may see tax deducted in the United Kingdom, receive a confusing coding notice, or discover that a deferral lump sum has been taxed even though the pension is now connected with life in France. The practical question is not simply “where is my pension paid?” It is which pension was paid, where the recipient was tax resident when it was paid, which article of the France–UK tax treaty applies, and whether the amount deducted was genuinely UK income tax. That distinction determines whether the remedy is a future exemption at source, a repayment claim to HMRC, a correction in the French return, or a challenge to a French assessment. This guide deals with the UK State Pension of a person who is resident in France after Brexit. It separates that benefit from a private occupational pension, a purchased annuity and a UK public-service pension, because those categories can produce different results. It then sets out an evidence-led route for stopping an incorrect deduction and recovering tax already taken.

I. Is a UK State Pension taxable in France or the UK after Brexit?

A. Why French tax residence usually moves the taxing right to France

Brexit did not cancel the bilateral income-tax treaty. The relevant instrument is the convention signed in 2008 and published in France by Décret n° 2010-20 and the France–UK double-taxation convention. For an ordinary pension paid for past employment, Article 18 is the starting point. Its English wording says that such pensions “shall be taxable only in that State”, meaning the state where the recipient is resident, subject to the specific public-service exception in Article 19(2). The treaty is therefore more important than the fact that the payment leaves a British bank account or is administered by a British institution.

Residence must be established before applying the pension rule. Under Article 4 A of the French General Tax Code (CGI), a person whose domicile fiscal, meaning tax residence, is in France is generally assessed on the whole of their income. The Code describes that liability as being “en raison de l’ensemble de leurs revenus”. In practical terms, a French tax resident cannot omit a UK pension merely because it is paid abroad. Conversely, a person who is not French tax resident does not become taxable in France on every foreign receipt simply because they own a French property or visit family there.

Article 4 B of the CGI identifies the familiar tests: the household or principal place of stay, the main professional activity and the centre of economic interests. The treaty has its own tie-breaker in Article 4. If both countries treat an individual as resident under domestic law, the analysis moves through the permanent home, the centre of vital interests, habitual abode and nationality. A British passport is relevant only at the later stage; it does not decide the question on its own.

The evidence should match the year being examined. A French home occupied as the family’s ordinary residence, a French tax return, a foyer fiscal, meaning the tax household, French utility records, health-registration evidence and the location of day-to-day financial activity may all matter. A second home in France, regular holidays or a French bank account are different facts. Keep the departure date from the UK, the date the French home became your principal home and any period in which you genuinely divided your life between the two states.

French administrative litigation shows why the file must contain evidence rather than labels. In Conseil d’État, 14 February 1979, no. 06961, the court considered that the “seule circonstance qu’il soit de nationalité britannique” was not enough, by itself, to prove treaty residence in the United Kingdom. The case concerns an earlier treaty and an older factual setting, so it is not a substitute for the current convention. It remains a useful warning: nationality and the origin of a pension cannot replace proof of actual treaty residence.

The same point appears in a different factual direction in CAA Bordeaux, 11 June 2013, no. 12BX00169. The court treated a person receiving a UK pension, without other UK activity or income of the kind relied upon in the case, as having French tax domicile on the evidence before it. The decision predates Brexit and the present treaty wording, but it illustrates the sequence that remains sound: establish residence, classify the pension, then apply the treaty article.

For a person who is genuinely resident in France, the ordinary conclusion is therefore that the UK State Pension must be declared in France and taxed there under French rules, with treaty relief preventing a second UK charge where Article 18 applies. “Taxable in France” does not mean “tax-free”. The amount may affect the French income-tax calculation, the applicable rate and certain social charges, depending on the household’s complete position. It also does not mean that every deduction visible on a UK statement is automatically refundable: the nature of the payment and the legal basis for the deduction must first be identified.

The broad tax and declaration background is set out in our broader Brexit tax overview for UK pensions. The present article addresses the narrower problem that arises after a deduction or an HMRC refusal, so that a reader can assemble the right claim rather than repeat a general declaration.

B. Why a State Pension is not the same as a UK government-service pension

The phrase “UK pension” covers several legally different payments. The UK State Pension is a National Insurance benefit based on the claimant’s contribution record. A private pension may be paid from a personal pension, workplace scheme or defined-benefit arrangement. A purchased annuity is a regular payment bought with capital. A public-service pension may be paid for government employment. The payer, the award letter and the tax document should be read together; the bank description alone is not a reliable classification.

HMRC’s PAYE guidance explains that the State Pension is not treated as a government pension for this purpose. The distinction is recorded in HMRC PAYE81025. The general treaty rule for an ordinary past-employment pension is Article 18, while Article 19 of the France–UK convention deals with government service. Article 19 can leave taxing rights with the paying state, subject to its nationality and residence exception. A former civil servant, armed-forces employee or local-government employee must therefore not use a State Pension exemption request without checking whether the payment is in fact a public-service pension.

The UK government’s explanation of State Pension collection is equally important. It states: Your State Pension is taxable income, but tax is not taken off before you get it. The same guidance explains that HMRC normally looks at total taxable income, including the annual State Pension entitlement, rather than treating each payment as a separate final tax calculation. A deduction shown on a statement should prompt an investigation into what was paid and who deducted it.

Several situations can create an apparent State Pension withholding:

• a State Pension deferral lump sum, which has its own tax-reporting treatment;
• an arrears payment or adjustment recorded together with the regular pension;
• a separate private or occupational pension paid by another administrator;
• a UK tax code applied to another source of income, while the recipient assumes it relates to the State Pension;
• a Simple Assessment or Self Assessment liability collected after the payment, rather than tax deducted by the pension payer; or
• a French deduction mistaken for UK tax because the net amount arrived after a cross-border transfer.

Ask the paying body for a payment history that separates the basic State Pension, increases, arrears, deferral lump sums and any tax line. Ask HMRC for the tax calculation and the source reference attached to the deduction. If the paperwork names a workplace scheme or a Civil Service, NHS, armed-forces or local-authority pension, stop the State Pension analysis and apply the correct treaty category. A claim can fail simply because the applicant asks for Article 18 treatment for an Article 19 payment.

A related trap is the difference between the place of payment and the place of taxation. A French bank account does not make a UK benefit French-source income, and a British account does not preserve UK taxing rights when Article 18 assigns the ordinary pension to the state of residence. The legal classification is also distinct from social-security coverage. An S1 certificate, CPAM registration or French health contribution can be relevant to other parts of the move, but none of them alone proves that a particular pension deduction is lawful income tax.

Finally, the treaty does not create an automatic exemption merely because a person holds a French residence card. A residence permit is an immigration document; a treaty claim is a tax-residence claim. The French tax office must be able to certify the relevant residence period, and HMRC must be able to match the claim to the correct income stream and tax years. That is why the evidence pack should explain the timeline instead of sending only a passport and a bank statement.

II. How can a British resident stop UK withholding and recover tax already taken?

A. Which form, evidence and French declaration should you prepare?

The first practical distinction is between future relief and a past repayment. Future relief asks HMRC or the payer to stop UK income tax being taken from payments that should be taxed in France. A past repayment asks HMRC to return UK income tax already deducted. The two requests can be presented together, but the form must identify both the future payments and each historic deduction. Do not describe every amount as “State Pension” if the statement contains a private pension, annuity or deferral lump sum.

For an individual resident in France, the official France–Individual double-taxation form and its official notes are designed to claim relief at source and repayment of UK income tax. The publication page provides the current form and supporting documents. It expressly covers an individual resident in France receiving a UK State Pension, pensions, purchased annuities, interest or royalties arising in the UK. The form is not a general letter of complaint; incomplete classification and missing residence certification are common reasons for delay.

Complete the sections relevant to the income actually received. For a regular State Pension, identify the payer, National Insurance number, gross annual entitlement and the years in which you were resident in France. If the issue concerns a deferral lump sum or another pension, describe it separately and attach the award or payment notice. If you claim a repayment, list the tax year, gross amount, date, tax deducted and document proving the deduction. The official France Individual notes published with the form explain that a resident of France can apply to have the UK State Pension exempted from UK income tax under the convention and can claim repayment if relief at source was not arranged.

The French tax authority normally certifies the residence section. The relevant office is the Service des impôts des particuliers, or SIP, meaning the individual tax office. Use the office shown in your French tax account or tax notice, and retain a complete copy of the signed form. If the form asks for a French tax reference, include it exactly as shown on the avis d’impôt, meaning the French tax assessment notice. A cover letter should state the move date, the tax years, the treaty article relied upon and the precise relief requested.

A strong evidence pack should usually contain:

• the UK State Pension award letter and a year-by-year payment statement;
• any P60, P45, tax-code notice, HMRC calculation or DWP correspondence showing tax;
• the National Insurance number and the claimant’s full name as held by the UK payer;
• the French tax number, latest tax notices and the French residence address;
• proof of the date on which French tax residence began, including the household’s move timeline;
• the completed French tax returns for the relevant years, including the foreign-income schedules where applicable;
• bank statements showing the gross payment, deduction and net receipt, with unrelated transactions redacted; and
• a schedule reconciling each deduction to the document that proves it.

Do not send only the net amount. Treaty claims are checked against gross income, and a repayment cannot be calculated reliably where the tax line is not separated from exchange-rate charges, bank fees or social-security deductions. If the only document is a bank statement, request a formal statement from the payer before asserting that UK income tax was withheld.

The French declaration remains necessary even when the treaty assigns taxing rights to France and the UK pays the pension. The French tax administration’s pensions and retirement guidance explains that foreign pensions are reported according to whether they give rise to a credit equal to French tax or to another treaty mechanism. The current foreign-pension annex, form 2041-E, helps identify the country-specific treatment. The online return can also require form 2047, the foreign-income return, and the corresponding lines on form 2042. Box numbers can change with the tax year, so check the current declaration interface and the notices for that year.

Where the treaty gives France the taxing right and provides a French credit mechanism for income taxed or treated as taxed in the UK, the gross pension may appear in the foreign-income section and the treaty credit in the designated credit section. Where Article 18 means that the UK should not tax the ordinary pension, the French return is still the place to declare the income. The absence of UK tax does not remove the French reporting obligation. Keep a screenshot or PDF of the submitted return and the calculation used, especially if the UK refund claim says that the income is taxable in France.

This interaction is governed by domestic French provisions as well as the treaty. Article 170 of the CGI governs the income declaration and can require foreign income to be reported even where a treaty exempts it from French tax but includes it in a rate calculation. Article 204 A of the CGI describes the French income-tax collection system, including withholding by a debtor and instalments paid by the taxpayer. It does not turn a UK deduction into a French credit automatically. The source, treaty treatment and French declaration must be reconciled.

Before sending the form, write a one-page calculation. Column one should show the payment date and tax year; column two the gross State Pension; column three any amount identified as UK income tax; column four the French declaration line; and column five the relief or repayment requested. Mark uncertain items as uncertain. That simple schedule gives the French SIP and HMRC a way to compare the same payment without making them reconstruct the file from bank entries.

B. What if HMRC or the French tax office refuses, delays or miscalculates?

A refusal should be answered with a precise correction, not a second identical form. Ask for the decision in writing and identify the reason: no French residence certification, wrong pension category, missing tax year, insufficient proof of the deduction, a time-limit objection, or a disagreement about the treaty tie-breaker. Each reason calls for different evidence. A public-service classification requires the pension scheme and employment history; a residence dispute requires the year-by-year factual file; a repayment dispute requires the tax calculation and payment documents.

Check whether HMRC has confused the State Pension with a private or government-service pension. HMRC PAYE81750 explains the treatment of a UK State Pension payable to a non-resident and recognises that a claim to exemption can be made under a double-taxation agreement. That guidance is useful when asking HMRC to explain the legal basis for a deduction, but it is not a substitute for the treaty and does not prove that the recipient was resident in France for every year claimed.

If the problem is a future deduction, ask HMRC to update the record and confirm the effective date in writing. If the problem is a past deduction, request repayment for each tax year and attach the supporting calculation. The official GOV.UK guidance on tax paid twice directs taxpayers to the relevant treaty and claim form and explains the role of the residence-state tax authority in confirming eligibility. Keep proof of delivery, copies of every attachment and the date on which the claim was made.

Do not assume that an HMRC repayment settles the French position. The repayment may be the correct result under Article 18 while the pension remains taxable in France. If the French return omitted the pension, correct it promptly. If France taxed the pension in a way inconsistent with the treaty, contact the SIP with the filed return, the assessment notice, the treaty analysis and the HMRC correspondence. A French objection is a separate procedure from a UK repayment claim.

French domestic deadlines must also be distinguished from the UK timetable. For a French income-tax claim, Article R*196-1 of the Book of Tax Procedures generally sets a deadline linked to 31 December of the second year following the assessment, notice, payment or event, subject to the rule applicable to the particular claim. Article R*196-1-1 contains a specific rule for claims concerning the French levy under Article 204 A, with a deadline tied to the last day of February of the following year. These are not a universal deadline for an HMRC repayment. The UK form, the relevant UK tax year and any statutory repayment limit must be checked separately.

If the two administrations disagree about residence or treaty interpretation, Article 26 of the convention provides a mutual-agreement route. The current treaty text allows a resident who considers that taxation is not in accordance with the convention to present the case to the competent authority, generally within three years of the first notification of the action giving rise to the dispute. This is not a reason to wait before making ordinary claims. It is a structured escalation for double-taxation or treaty application problems after the facts and domestic remedies have been documented. Link the submission to the official treaty text, including Article 26, and explain the precise relief sought.

A dual-residence dispute should include a residence matrix. List the number of days in each country, the location of the permanent home, where a spouse or dependent children lived, the main bank and investment relationships, health registration, work or business activity, and the place where the household’s ordinary life was organised. The treaty tie-breaker is factual. A British residence certificate, nationality or pension address may support the case, but each item must be considered with the French facts and the relevant tax year.

There are also procedural warning signs that justify a pause before filing. If the letter refers to a “government pension”, check the employer. If the payment includes a lump sum, check whether it was a State Pension deferral lump sum or a private pension commutation payment. If the deduction is called PAYE but the payer is DWP, request clarification. If the French notice includes social contributions rather than income tax, identify the contribution and its legal basis. A reimbursement request that bundles all these amounts together will often be rejected because the administration cannot match the request to a treaty article.

When the tax office does not respond, send a dated follow-up that repeats the reference number, attaches only the missing documents and asks three questions: has the claim been registered, which income category has been assigned, and what further document is required? Escalate through the administration’s published complaint or contact route while preserving the original claim date. For a material amount, a lawyer can audit the treaty classification, check the French declaration and prepare a reasoned response or mutual-agreement file. The objective is a traceable decision on each payment, not an informal assurance that the next pension will be paid net.

Finally, calculate the real financial result after both countries’ rules have been applied. A UK refund can increase the amount received, but the same gross pension may increase French income tax or alter the household’s effective rate. Conversely, a French correction may reduce a French assessment without producing a UK refund if the UK was entitled to tax a public-service pension under Article 19. Keep the calculation by tax year and do not treat the refund as an exemption from reporting.

Conclusion

For a British citizen who is tax resident in France, the ordinary UK State Pension is usually analysed under Article 18 of the France–UK convention, not under the rule for a government-service pension. The first task is to identify the payment and prove French residence for the relevant years. The second is to distinguish a genuine UK income-tax deduction from a deferral lump sum, another pension, a tax calculation or a French charge. The France–Individual form can be used to seek future relief and repayment, with French residence certification and a payment-by-payment evidence schedule. The pension still belongs in the French return, using the current foreign-income instructions. If an administration refuses, obtain the written reason, correct the classification, preserve the claim date and use the domestic objection or treaty mutual-agreement route where necessary. A careful file can stop an incorrect UK deduction without creating a new reporting error in France.
