National Insurance When You Live in France: What Happens to Your UK Record (2026)

If you are leaving the UK for France, National Insurance is probably the part of your paperwork you think about least. It matters because National Insurance contributions build your UK State Pension, and the rules for paying them from abroad changed on 6 April 2026. This guide explains what happens to your record, who can still pay voluntary contributions, when you can stay in the UK system, and how this meets French social contributions.

It describes the rules as the official pages state them. It is not personal advice: HMRC decides what you can pay, and the French authorities decide what you owe in France.

What happens to your National Insurance record

Nothing is deleted when you leave. Your record keeps the years you have built, and those years still count if you claim the State Pension later. GOV.UK says you need 10 qualifying years on your record to get any new State Pension, and that a year counts if you paid National Insurance, received National Insurance credits, or paid voluntary contributions. The same page says you might also qualify if you have lived or worked abroad.

What changes is that, once you live and work in France, you normally stop adding years. GOV.UK says that if you work abroad you will usually pay social security contributions in the country where you work. For most people who take a job or start a business in France, that means the French system.

That can leave gaps in your UK record. A gap is not a penalty, but it may reduce the pension you receive. The question is whether it is worth filling.

Check your State Pension forecast first

Before you pay anything, see where you stand. The State Pension forecast shows how much State Pension you could get, when you can get it, and whether you can increase it, for instance by paying to fill gaps in your National Insurance record.

To use the online service you need GOV.UK sign-in details, and you may be asked to prove your identity, usually with photo ID. You can also check through the HMRC app. If you will reach State Pension age in more than 30 days, the page says you can complete form BR19 and post it, or call the Future Pension Centre to have the forecast posted to you.

The forecast service is not available if you already receive your State Pension or have deferred claiming it. In that case GOV.UK says to contact the Pension Service in the UK or the International Pension Centre from abroad.

For what the pension itself does once you live in France, see our guide to the UK State Pension in France.

Voluntary contributions from abroad

GOV.UK says that voluntary National Insurance can protect your benefit entitlement and your State Pension, whether you return to the UK or stay abroad. It also says voluntary National Insurance does not cover health insurance in the country where you live. That matters in France, where health cover is arranged separately.

The rules changed on 6 April 2026

The GOV.UK page on living or working abroad sets out two sets of rules.

For the 2025 to 2026 tax year and earlier, you needed to have lived in the UK for 3 years in a row, or paid (or been treated as paying) contributions for at least 3 years in total. Class 2 had two extra conditions: you worked in the UK immediately before leaving, and you are working or worked while abroad.

From the 2026 to 2027 tax year, the page says you cannot pay voluntary Class 2 National Insurance contributions for time abroad. You can apply for Class 3 for time abroad after 5 April 2026 if you have either 10 years of continuous UK residence or 10 years of qualifying contributions in total.

The page lists what counts as qualifying contributions: Class 1, 2 or 3 paid in the UK, certain Class 1 or 2 paid while working abroad under a Social Security Agreement, Class 1 paid by posted workers for their first 52 weeks abroad, and Class 2 paid by volunteer development workers. It says other voluntary contributions for abroad periods and National Insurance credits do not count.

Transitional rules

If you were already in the process before the change, you may be able to keep the older 3 year test. The page says all of the following must apply:

• You applied for Class 2 or Class 3 for 2024 to 2025 or 2025 to 2026 on or before 5 April 2026.
• You pay, or have paid, those contributions on or before 5 April 2027.
• You apply for Class 3 for 2026 to 2027 on or before 5 April 2027.

These transitional rules stop applying once you return to live or work in the UK.

Deadlines

GOV.UK says you can only pay voluntary contributions for the past 6 years, and that payments are due by 5 April each year. Its example: for the 2025 to 2026 tax year, you have until 5 April 2032 to fill gaps. That page does not cover exceptions, so check with HMRC if your case is unusual.

How to apply

You apply with HMRC’s online service for form CF83. You will need your National Insurance number, your UK and overseas addresses, the date you left the UK, and details of your employment before leaving and any work abroad. Online applications need a phone with a working camera and one photo ID from the list on the page.

If you are below State Pension age, GOV.UK says to check your State Pension forecast or contact the Future Pension Centre. If you are over State Pension age or within 6 months of it, HMRC says it cannot process your application, and you contact the International Pension Centre instead. If approved, HMRC writes to confirm payment dates and amounts. The pages do not give rates in the text we read, so look them up on GOV.UK for the tax year in question.

HMRC also notes that you can only pay voluntarily to one system at a time, and that you may owe compulsory contributions abroad.

When you can stay in the UK system

The general rule is one country at a time, usually where you work. There are exceptions where you stay in UK National Insurance, and each needs a document from HMRC.

GOV.UK says you only pay National Insurance in the UK if HMRC has issued you with a certificate of coverage. The EU guidance page says this certificate is also called a PDA1, and it lists who should apply:

• Employees employed by a UK employer who is normally based in the UK and sent or agreed to work temporarily in an EU country for up to 2 years.
• Self-employed people in the UK who temporarily do a similar activity in an EU country for up to 2 years.
• People who work in the UK and one or more EU countries at the same time.

Be careful here. That page says you must be within the social security coordination rules of the Withdrawal Agreement. Its examples include UK nationals who were resident or started working in an EU country before 1 January 2021. It does not mention the Trade and Cooperation Agreement.

For people who move later, a DWP staff guide says that the Trade and Cooperation Agreement includes a Protocol on Social Security Coordination, that the one-country-at-a-time rule applies with exceptions including posted workers, and that all member states have opted in to the posted worker provision. The same guide adds that member states can opt out in the future. It is a 2021 document and says it is not a definitive statement of the law. On the French side, the French government’s Brexit site says France has kept the Posting of Workers Regime for both French and British workers.

In practice, if your UK employer is sending you to France, ask HMRC and your employer which certificate applies to you and for how long. GOV.UK also says HMRC and the other country can agree to keep you in UK National Insurance in exceptional circumstances.

How this meets French social contributions

The coordination principle is one system at a time, so French contributions replace UK National Insurance rather than adding to it. The part to watch is CSG and CRDS.

Service-Public says that a tax resident of France who works in an EU or EEA country or Switzerland and is affiliated to compulsory social security there is not subject to CSG and CRDS on that basis. The countries it lists are EU, EEA and Switzerland. The UK is not among them, so do not assume that rule covers a UK affiliation.

For a foreign pension, the tax administration’s BOFiP says pensions of foreign source are subject to CSG, CRDS and CASA when the person is tax resident in France and is covered by a French compulsory health insurance scheme, and the applicable tax treaty does not exclude French taxation of the pension. It adds that for foreign-source pensions the contributions are collected by the DGFiP, not by the social bodies. For the tax side, see our guide to the UK France tax treaty and HMRC.

If you are a pensioner, health cover is a separate question, covered in our guide to the S1 form.

What to do in order

1. Check your State Pension forecast.
2. Decide whether any gap is worth filling, and whether you qualify under the 10 year test or the transitional rules.
3. If you are being sent to France by a UK employer, ask about a certificate of coverage before you go.
4. Keep the deadline in mind: voluntary payments are limited to the past 6 years.
5. For the wider move, see moving to France from the UK.

FAQ

Do I lose my National Insurance record if I move to France?

No. GOV.UK describes a record that keeps the years already built. What you lose is the chance to add years by working in the UK.

Can I still pay voluntary Class 2 from France?

Not for time abroad from the 2026 to 2027 tax year, according to GOV.UK. Earlier years may still be possible under the old rules, with the transitional conditions above.

How many years do I need to pay voluntary Class 3?

For time abroad after 5 April 2026, GOV.UK says 10 years of continuous UK residence or 10 years of qualifying contributions. Transitional rules apply to those who applied earlier.

Is there a deadline?

GOV.UK says you can only pay for the past 6 years, with payment due by 5 April each year.

Will voluntary contributions give me health cover in France?

No. GOV.UK says voluntary National Insurance does not cover health insurance in the country where you live.

Who do I contact if I am near State Pension age?

If you are over State Pension age or within 6 months of it, GOV.UK says to contact the International Pension Centre.
