Tax in France for non-residents: the complete guide

Living abroad does not mean France has no claim on your income, but as a non-resident, you are taxed only on your French-source income, and often far less than you fear. Between the minimum tax rate, the average-rate option, reduced social levies and tax treaties, several legal levers cut the bill. You just need to know them.

This guide covers the essentials: how France decides whether you are a resident, what it taxes when you are not, the minimum rate and the average-rate option, social levies and how to recover them, rental income, real-estate capital gains, investment income, the exit tax, tax treaties, filing, the fiscal representative and coming back to France. With a worked example, a checklist and the order in which to pull the levers so you never pay a euro more than you must.

Are you a French tax resident?

Everything starts here. Under French law (article 4 B of the tax code), you are a French tax resident if any one of these applies: your home or main place of stay is in France; your main professional activity is in France; or the centre of your economic interests is in France. A single criterion is enough to make you a resident.

You are a non-resident only when none of these criteria is met, when your home, your work and your economic centre have all genuinely moved abroad. Holding a foreign visa or spending time abroad is not, on its own, decisive: what matters is where your life is actually centred.

This distinction governs everything that follows. A resident is taxed in France on worldwide income; a non-resident, only on French-source income. Establishing your status clearly, and being able to evidence it, should the administration ask, is therefore the foundation of your whole tax situation, and the first thing to settle.

What France taxes when you are a non-resident

As a non-resident, you are taxed in France on your French-source income only. Income arising elsewhere, your foreign salary, foreign dividends, gains realised as a resident of another country, falls outside the French net. France keeps the right to tax what is connected to France, and lets the rest go.

This territorial principle is the good news of non-residence: the broad worldwide taxation of a French resident gives way to a narrower base. The whole exercise then becomes identifying what remains French-source, and then applying the right rate and the relevant treaty to that French-source income.

Understanding this is what separates a calm, optimised situation from an anxious, over-taxed one. Many non-residents pay too much simply because they do not know which income stays French-source and which levers apply to it, and that the default minimum rate is not the rate they must actually bear, once the average-rate option is properly claimed on the annual return.

French-source income: the main categories

The most common French-source incomes for non-residents are: rental income from property located in France; capital gains on French real estate; certain dividends and interest paid by French entities; salaries for work physically performed in France; and, in some cases, pensions paid from France, depending on the treaty.

Each category has its own rules of rate and method, and each interacts with the treaty between France and your country of residence. The same logic runs through all of them: France may tax the French-source element, and your country of residence then eliminates any double taxation, by exemption or by credit, depending on the treaty.

Mapping precisely which of your incomes are French-source is the practical starting point of any non-resident tax review. It defines the base on which the levers, minimum rate, average-rate option, reduced social levies, treaty relief, will then operate within that single framework, in a defined order.

The minimum rate and the average-rate option

French-source income of a non-resident is subject to a minimum tax rate: 20% up to a threshold, then 30% above it. The administration applies at least this rate, unless you can justify a lower one. For modest incomes, this 20% minimum can feel surprisingly high, which is exactly what the average-rate option is there to correct.

The key lever is the average-rate option. Instead of the 20/30% minimum, you may ask to be taxed at the average rate that would result from applying the progressive scale to your worldwide income, if that rate is lower. For many non-residents, this average rate is well below 20%, sharply cutting the tax due. The worldwide income reported for this purpose only sets the rate, France still taxes the French-source income alone, never the foreign income merely disclosed for the purpose of the rate.

This option is requested when you file, and the administration applies the more favourable of the two. It is the single most important reflex for a non-resident with French income, and the one most often missed, at real cost, sometimes for years.

Social levies: 17.2% or 7.5%

Alongside income tax, French capital income (rents, real-estate gains) bears social levies. The standard rate is 17.2%, but it drops to 7.5%, the solidarity levy alone, if you are affiliated to a social security scheme in the EEA, Switzerland or the UK, under settled EU case law (the De Ruyter line).

This is frequently misapplied: many non-residents affiliated elsewhere in Europe pay 17.2% instead of 7.5%, and can reclaim the wrongly levied CSG-CRDS for past years. By contrast, someone affiliated to a third-country scheme (outside the EEA/Switzerland/UK) remains subject to the full rate, a nuance confirmed by the Jahin case for third-country residents. Affiliation to a social-security scheme, not residence as such, is what determines whether the 7.5% or the full 17.2% rate applies to your French capital income.

Checking your social-security affiliation and the rate actually applied is therefore essential: the 9.7-point gap is far from trivial on recurring income or a large gain. Where you have overpaid, the levy can be recovered for the years that are not yet time-barred, on a contentious claim supported by proof of affiliation.

Rental income from French property

Rent from a property located in France is French-source and taxable in France. It is subject to the minimum rate (with the average-rate option available) and to social levies (17.2% or 7.5%). You choose between the simplified micro regime (a flat allowance) and the actual regime (deducting real expenses, with the possibility of a deductible loss).

The actual regime is advantageous as soon as your expenses, loan interest, works, property tax, management, exceed the flat allowance, and it can neutralise the taxable income for several years on a recently financed property. Furnished letting follows a different, business-income regime, with depreciation that can sharply reduce the taxable result.

Combining the right regime with the average-rate option and the correct social-levy rate is what minimises the tax on your French rents. Each lever matters, and together they can divide the bill several times over.

Real-estate capital gains

When you sell a French property, the capital gain is taxable in France (the property’s location), at the standard rate (a 19% tax plus social levies), with allowances for the holding period that progressively reduce the base and can, after enough years, lead to full exemption.

As with rents, the social levies on the gain can be reduced to 7.5% for someone affiliated to a social security scheme in the EEA, Switzerland or the UK. And a fiscal representative may be required for a seller established outside the EEA above a certain sale price, a point to anticipate, as it carries a cost and a delay.

A sale is therefore a tax event in its own right, distinct from receiving rent, and deserves its own preparation: the gain, the allowances and the formalities should all be anticipated well before signing.

Dividends and investment income

Dividends and interest from French sources paid to a non-resident may bear a withholding tax in France, the rate of which is often reduced or reallocated by the treaty with your country of residence. The treaty typically lowers the French withholding and grants a credit in your country of residence.

Investment income arising outside France, from a foreign brokerage account, for instance, is, by contrast, generally outside the French net for a non-resident. This is one reason expatriates often realise securities gains while non-resident, outside the reach of French tax.

The exact treatment depends on the source of the income and the applicable treaty, which should be read rather than assumed. The interaction of French withholding at source and treaty relief together determine what you ultimately pay on French salaries and pensions.

Salaries and pensions of non-residents

A salary paid for work physically performed in France remains French-source and taxable in France, even for a non-resident, typically through a specific withholding. Work performed abroad, by contrast, is generally outside the French net, the place where the activity is carried out is what matters.

Pensions are more treaty-dependent. Depending on the treaty and the type of pension (private, public, social security), the right to tax may fall to France or to your country of residence. Retirees abroad should therefore check the applicable treaty carefully rather than assume their French pension is, or is not, taxed in France.

These categories illustrate the same principle once more: the source of the income and the treaty together decide where it is taxed. Salaries follow the place of work; pensions follow the treaty’s own specific provisions, which often differ between private pensions and public-sector pensions paid by the State.

The exit tax

If you left France holding a large portfolio of securities (broadly, at least €800,000, or a 50% stake in a company), you may be within the scope of the French exit tax on unrealised gains at departure. It is, however, an unusual tax: typically deferred, and ultimately cancelled if you keep your securities beyond the required period.

Real estate and directly held cryptocurrencies are outside its base. For most people who left France, the exit tax is therefore reported and monitored rather than actually paid, provided the formalities and any required guarantees are handled correctly.

If you left with significant holdings, it is worth confirming whether the exit tax applied to you and that your deferral is properly in place. It is a once-off departure matter, but one not to overlook.

Tax treaties: avoiding double taxation

The tax treaty between France and your country of residence is the master key. It allocates the right to tax each type of income, defines a single country of residence in case of conflict, and provides the mechanism, credit or exemption, that eliminates double taxation.

In practice, French-source income is taxed in France, and your country of residence then relieves the double charge under the treaty. Reasoning "in general" is a mistake: each treaty has its own provisions, and the right reflex is always to read the applicable one for each category of income, rather than relying on a general impression.

The treaty is what makes the whole picture coherent, turning two national systems into a single, non-duplicative outcome. It is the document to consult whenever a French-source income and a foreign residence meet.

Filing your return

A non-resident files with the non-resident tax office (the dedicated service for individuals living abroad). This is where you declare your French-source income, request the average-rate option, and claim the reduced social-levy rate where it applies.

The return is the moment when the main levers are actually exercised: the right regime, the right rate and the right level of social levies all flow from a careful, complete and accurate filing. It is an active process, not an automatic one.

Filing well is therefore the practical key to a fair tax outcome. It is where you assert, in concrete terms, the position the rules allow you, rather than accepting the default minimum rate, which surprisingly few non-residents realise they are entitled to challenge.

The fiscal representative

The fiscal representative is an intermediary that some non-residents must appoint. For ordinary rental income, it is generally not required. It becomes relevant on the sale of a property: a seller established outside the EEA may be required to appoint an accredited representative above a certain sale price, where an EEA resident is exempt.

Because the appointment carries a cost and a delay, it should be anticipated well ahead of a planned sale, and built into the timetable. For simply receiving rent, it usually remains a secondary issue.

Knowing in advance whether a representative will be required avoids last-minute complications at the notary. It is one of the formalities that distinguish a smooth sale from a stressful one.

Coming back to France

A return to France can be prepared and optimised. Before returning, it is often wise to realise (purge) latent gains while still non-resident, outside the reach of French tax, so as not to import an expatriation gain into France. On return, the impatriate regime may apply to those recruited after at least five years abroad, with a partial exemption for several years.

The pairing of "purge before return + impatriate regime on return" is the most powerful optimisation of a return to France. But it must be anticipated: these levers are prepared during the expatriation, not at the last minute.

Thinking about your return from the moment you leave is what lets you make the most of your time abroad, both on the way out and on the way back. It turns a simple relocation into a planned, tax-efficient journey, on both legs of the trip.

The year you move: a split treatment

The year you leave or return to France is special: you are treated as a resident for part of the year and a non-resident for the other, split at your date of change. Worldwide income is taxed for the resident period; only French-source income for the non-resident period.

This split makes the timing of income and disposals within that year important. Realising a gain just before or just after the change of residence can produce very different outcomes, since one side of the line is taxed on worldwide income and the other only on French-source income.

Handling the year of the move correctly, the split return, the date of change, the timing of any disposals, avoids both double counting and missed opportunities. It is one of the moments where careful sequencing genuinely pays.

Common mistakes

1. Assuming a foreign visa ends French residence. Status depends on the article 4 B criteria, not on a residence permit.

2. Accepting the 20% minimum without requesting the average-rate option.

3. Paying 17.2% social levies when entitled to 7.5% (EEA/Switzerland/UK affiliation).

4. Forgetting to reclaim CSG-CRDS wrongly levied in past years.

5. Overlooking the fiscal representative before a property sale (non-EEA).

6. Fearing double taxation when the treaty actually neutralises it.

Your checklist

As a non-resident with French income:

1. Confirm your status under article 4 B and keep evidence of it.
2. Map your French-source income (rents, gains, dividends, salaries).
3. Request the average-rate option if it beats the 20/30% minimum.
4. Check your social-security affiliation to obtain 7.5% instead of 17.2%.
5. Reclaim past CSG-CRDS if you were wrongly charged.
6. File with the non-resident tax office using the correct forms.
7. Read the applicable treaty for double-taxation relief.
