French Income Tax for Newcomers (2026): Residence, Withholding, and Filing
France taxes you on your worldwide income once you become a French tax resident — and it collects that tax at source, straight from your paycheck, from day one. Newcomers face three questions: am I a tax resident, what rate is withheld from my salary before my first tax return, and how do I file for the first time? Here are the answers, plus the 2026 brackets and the basics of social charges.
Are you a French tax resident? The four criteria
Under article 4 B of the French tax code, you are considered fiscally domiciled in France if you meet any one of these criteria: (1) your foyer (home) is in France — the habitual residence of you, your spouse or partner, and your children; for a single person without children it is where you habitually live; (2) France is your main place of stay — at least 183 days in the year, i.e. more than 6 months; (3) you carry out your main professional activity in France (unless it is merely ancillary); (4) France is the center of your economic interests (main investments, business seat). Tax treaties can override these domestic rules, so check the treaty between France and your previous country of residence. Tax residents are taxed on worldwide income; non-residents only on French-source income.
Prélèvement à la source: tax collected from day one
Since 1 January 2019, income tax is collected as income is earned. For employees, the employer withholds it from each paycheck using a rate transmitted by the tax office. The mechanics for a newcomer:
- Personalized rate (taux personnalisé): calculated by the tax office from your last tax return and updated each September. Until you have filed a return, the office cannot compute one for you.
- Default rate (taux par défaut / non personnalisé): applied when no personalized rate exists. It follows a statutory grid based on your monthly taxable salary, from 0% to 43%. It ignores your family situation, so it often over-withholds for married couples — any overpayment is settled when you file your return.
- You can keep your rate from your employer by opting for the non-personalized rate; the employer then applies the neutral grid rate instead.
- Married or PACS couples: since September 2025 the default is an individualized rate per spouse (taux individualisé); you can keep the single household rate (taux foyer) on request.
- Self-employed: there is no employer to withhold — you pay monthly or quarterly advance payments (acomptes contemporains), which you set up on impots.gouv.fr.
You can adjust your rate at any time from your personal space on impots.gouv.fr ("Gérer mon prélèvement à la source"), and the new rate applies within 1–2 months. The annual return reconciles everything: it sets the definitive tax and your new September rate.
The 2026 tax brackets
Caution: France's brackets are reset each year by the finance law. The brackets labelled "2026" apply to income earned in 2025 (declared in spring 2026). They were set by the 2026 finance law, promulgated 19 February 2026, indexed +0.9% for inflation:
| Taxable income per share (quotient familial) | Rate |
|---|---|
| Up to €11,600 | 0% |
| €11,601 – €29,579 | 11% |
| €29,580 – €84,577 | 30% |
| €84,578 – €181,917 | 41% |
| Above €181,917 | 45% |
Tax is computed slice by slice, and each adult counts as one "part" (a couple: 2 parts; children add half-parts, with a cap). The brackets that will apply to income earned in 2026 (declared in spring 2027) are not set yet — they will come with the next finance law. Check the official site before computing anything.
Mini-example (illustrative only): a single newcomer with €50,000 of net taxable 2025 income. Tax = 11% × (29,579 − 11,600) + 30% × (50,000 − 29,579) = 11% × 17,979 + 30% × 20,421 ≈ €1,978 + €6,126 = €8,104. Your actual tax depends on your parts, deductions and the décote.
Your first tax return in France
If you arrive in France in 2026, your first French return is filed in spring 2027, covering income received after you became tax resident. Two practical points:
- Paper first, online later. Online filing is the norm in France, but you need an online access number and a revenu fiscal de référence to create your impots.gouv.fr account. Newcomers who have neither must file a paper return (form 2042) the first year, downloadable from impots.gouv.fr, sent to your local tax office (service des impôts des particuliers). Once processed, you receive your identifiers and file online from year two.
- Split reporting for the arrival year. French-source income earned before your move (e.g. French rental income while still abroad) goes on form 2042-NR for non-residents; everything from your arrival date goes on the standard 2042. If you moved mid-year, check the official site for which forms cover your case.
Filing deadlines run in spring (May–June) and differ between paper and online, and by département — check the official site each year.
Social charges: CSG and CRDS in one minute
On top of income tax, France levies social charges. For employees:
- CSG (contribution sociale généralisée): 9.2% on earned income, calculated on 98.25% of gross salary (a 1.75% flat allowance for professional expenses). Part of the CSG (6.8 points) is deductible from taxable income.
- CRDS (contribution au remboursement de la dette sociale): a flat 0.5% on the same base, not deductible.
Together 9.7% — visible on your payslip, withheld by the employer alongside income tax. They apply because you are affiliated with the French social security system, not because of your nationality. On investment income the combined social charges are higher — check the official site for current rates.
Frequently asked questions
I arrived in September 2026. Am I a tax resident for 2026?
Quite possibly — one criterion is enough. If France is now your foyer, or your main professional activity is in France, you are resident from your arrival date, and your worldwide income from that date is reportable in France. Check the tax treaty between France and your previous country, which can change the answer.
My employer withholds 9% but my real rate should be lower. Do I get it back?
Yes — withholding is only an advance. Your spring tax return computes the definitive tax; overpaid amounts are refunded (usually in summer), underpaid amounts are collected.
I have no French bank account yet. Can I still file?
A French IBAN is needed for refunds and direct debits. You can file the return without one, but open the account before the refund and collection cycle — check impots.gouv.fr for the current procedure.
Do I pay French tax on my foreign bank interest?
If you are a French tax resident, yes — worldwide income is in scope, with treaty relief and foreign tax credits where applicable. This is exactly where professional advice pays for itself.
What is the décote I see on my tax notice?
A reduction mechanism for modest tax bills — it lowers or zeroes out income tax below a threshold set each year. Check the official site for the current threshold.
