You hear a lot of contradictory things about tax residency.
I wanted to get a clear picture before leaving — whether for optimisation or simply to travel with peace of mind.
Changing your tax residency generally concerns long-term expatriation, not a simple trip of a few months.
If you are planning a long departure, I also cover this in 6 Months in Asia, and the hesitation itself in I don’t know if I should leave.
Here is what I found.
🇫🇷 Who this article is for: it covers French tax residency only — whether France still treats you as a tax resident once you leave. It concerns anyone living in France, whatever their nationality. It does not cover the rules of the country you are heading to: those apply on top, and are worth checking separately. The official sources quoted at the end are pages from the French tax authority, in French.
🟦 The essential takeaway
After 6 months abroad, your tax residency does not change automatically. You remain a French tax resident if your home, your main occupation, or the centre of your economic interests remains in France. You must then continue to declare your worldwide income.

🟧 The 183-day rule: the big misunderstanding
What everyone says (and which is wrong)
“After 183 days abroad, you are no longer a French tax resident.”
This threshold does exist: it can serve as a marker for assessing where your main stay is, and it also appears in certain international tax treaties. But in France, it is not duration that decides — it is where the real centre of your life sits.
⚠️ Careful: it is not a simple count of days that determines your tax residency. A single one of the legal criteria is enough to keep you a French tax resident.
🟦 The criteria for French tax residency
You are tax-domiciled in France if at least one of the following criteria is met. Just one is enough, before any tax treaty is applied.
| Criterion | Explanation |
|---|---|
| 🏠 Your home is in France | Where you usually live, where your spouse, civil partner, or minor children live. |
| 📅 Your main stay is in France | If you spend more than 183 days a year there, or most of your time. |
| 💼 Your main occupation is in France | Even if you travel regularly, your job or main activity is carried out in France. |
| 💶 Centre of economic interests in France | Where you receive most of your income, where your investments and assets are located. |
💡 Worth remembering: it is not only a question of duration. Home, occupation and the centre of interests weigh at least as much. Even from a beach in Bali, the tax authorities look at your financial flows, not your scenery.
🟩 When do you actually become a non-resident for tax purposes?
A consistent, lasting shift
You may be treated as a non-resident if none of the domestic criteria still domiciles you in France, or if a tax treaty attributes your residency to the other country. In practice, it means genuinely transferring:
- Your centre of life
- Your main occupation
- Your centre of economic interests
It is not “I am leaving for a year and we will see.” It is a change you will need to be able to justify.
🟦 Non-resident: which taxes do you still pay?
Even as a non-resident, you remain taxable in France on French-source income that stays taxable there, subject to the tax treaty between the two countries:
- Rent from property located in France
- Income from a French business or activity
- French pensions and retirement income
Foreign-source income is generally no longer taxed in France once you are a non-resident, but the treaty between the two countries can change that. In short: if the money comes from France, the tax authorities will not forget you.
🟨 Non-resident tax rates
For 2025 income declared in 2026, the French-source income of non-residents is subject to a minimum rate:
- 20% up to €29,579 of net taxable income
- 30% on the portion above €29,579
It is not 30% on the whole amount: the progressive scale is calculated first, then these minimum rates apply to the brackets concerned. But there is a more advantageous option for smaller incomes: the average rate.
This average rate is calculated on all your income, French and foreign, then applied only to the income taxable in France. The tax authorities automatically apply whichever is more favourable to you. It is often worthwhile when your foreign income is low or non-existent. But if your foreign income is significant, the average rate can climb and become less advantageous. In complicated cases, or with significant amounts, it is better to seek advice from a tax specialist or an accountant who works with expatriation.
🟦 Tax residency and remote work
Blog, freelancing, a company: the key question
If you have a blog, a freelance activity or a company, the authorities can look both at where the activity is really run from and at where the centre of your economic interests sits. Where are your clients? Where does most of your income come from? That is what is examined — not your geographic location.
🟩 The transition year: the mismatch to anticipate
In the year you leave, the period before departure is treated as that of a resident; after departure, only French-source income that remains taxable is concerned. In practice:
- Withholding tax continues on the basis of your previous income until it is updated
- The adjustment comes with the following declaration and settlement
- Any refund follows the tax calendar for that year
💡 Good to know: if your income drops significantly, you can request an adjustment of your withholding rate directly on impots.gouv.fr.
🟦 FAQ — Tax residency and travel
| Question | Answer |
|---|---|
| Do I become a non-resident after 6 months abroad? | No. Duration alone is not enough. Your home, main occupation, and centre of economic interests are the deciding criteria. Just one of them in France is enough to keep you a French tax resident. |
| Will I be taxed on a salary I no longer receive? | No. No income, no withholding. But your rate may stay based on your previous income until it is adjusted. You can request an adjustment as soon as your income drops significantly. |
| Can I lower my withholding tax rate? | Yes. If your income drops significantly, request an adjustment on impots.gouv.fr. The change takes effect quickly and avoids an overpayment to sort out the following year. |
| How is a non-resident’s tax calculated? | A minimum rate of 20% up to €29,579 and 30% above that. You can opt for the average rate (article 197 A of the French tax code), calculated on all your worldwide income, often much more advantageous if your income has dropped. |
| What happens the year I leave? | There can be a mismatch between withholding and actual tax owed. The adjustment comes with the following declaration and settlement, and any refund follows the tax calendar for that year. |
