Income Tax in France: Brackets, Withholding and Filing (2026 Guide)

If you earn money in France, or you run a business here, French income tax will be part of your life. The French call it impôt sur le revenu (IR), and it is the main personal tax on salaries, dividends, rental income and business profit passed through to owners. This guide explains income tax in France in plain English: who pays it, the five brackets, how the bill is computed, and the 2026-2027 withholding and filing calendar.

Who pays French income tax

Two questions decide everything: where you are a tax resident, and where your income comes from.

If you are a French tax resident, you are taxed in France on your worldwide income. Residency is defined by tests, not by nationality. You are generally a French resident if your home (your foyer, where your family lives) is in France, or if you spend more than 183 days a year there. Having your main professional activity in France also counts. One test is usually enough.

If you are not a French resident, France taxes only your French-source income: salaries for work performed in France, French rental income, and most French dividends and capital gains. Double tax treaties shift these lines. Check the treaty with your country before assuming anything.

The five income tax brackets

French income tax is progressive: the rate rises with income, slice by slice. The scale below has applied since 1 January 2025, and it is the scale used on the return you filed in 2026 for your 2025 income.

Bracket	Taxable income (single person)	Rate
1	Up to EUR 11,497	0%
2	EUR 11,497 to EUR 29,315	11%
3	EUR 29,315 to EUR 83,823	30%
4	EUR 83,823 to EUR 180,294	41%
5	Above EUR 180,294	45%

A single person with EUR 40,000 of taxable income does not pay 30% on the whole amount. The first EUR 11,497 is taxed at 0%. The slice from EUR 11,497 to EUR 29,315 is taxed at 11%. Only the slice above EUR 29,315 is taxed at 30%. This slice-by-slice logic is the single most useful thing to understand about French income tax.

Applied to that EUR 40,000, the math gives: 0 on the first slice, then 11% on EUR 17,818 (about EUR 1,960), then 30% on EUR 10,685 (about EUR 3,206). The total comes to roughly EUR 5,165, an effective rate of about 13% on the full EUR 40,000. The top marginal rate of 45% only touches income above EUR 180,294.

These limits are revalued most years. The scale in force is the one shown on your annual tax notice (avis d'imposition) and on impots.gouv.fr, so check those limits rather than figures quoted in older articles.

How your tax is actually computed

Three mechanics sit between your raw income and your final bill.

First, the household. Income tax is computed at the level of the tax household (foyer fiscal). A married couple or civil partners file one return combining all income, and children add half or whole shares. The family quotient divides household income by the number of shares, applies the scale to one share, then multiplies the result back. The effect is that a second adult share and child shares pull the effective rate down. The tax benefit of each additional share is capped by law.

Second, allowances. If you are salaried or a pensioner, you can deduct a flat 10% allowance for professional expenses, capped at EUR 14,426 per year. The alternative is deducting your actual costs (commuting, meals, home office) if they exceed the flat allowance.

Third, offsets. Low incomes benefit from a decote, a discount that trims the tax just above the entry threshold, and certain situations open rights to tax credits and reductions. These amounts are netted against your tax before the final figure on your notice.

Pay as you go: withholding at the source

Since 2019, income tax is withheld at the source (prélèvement à la source, PAS). For a salaried person, the employer applies a withholding rate to the gross salary each month and transfers it to the tax office, the DGFiP (Direction générale des Finances publiques). For sole traders and consultants, the tax office itself collects monthly or quarterly instalments based on the latest return.

The rate is personal. The tax office computes it from your previous return and sends it to your employer. You can choose a neutral rate instead, which discloses nothing about your income to the employer. If your income changes materially, ask for the rate to be updated at any time. Doing so promptly avoids a large gap between what was withheld and what you owe. Our payroll services in France guide covers how withholding appears on French payslips.

Withholding does not replace the annual return. The return settles the year: extra tax above what was withheld becomes payable, and tax withheld above the final liability is refunded.

The balance and the four instalments

When your return shows a balance due above EUR 300, the amount is collected in four equal instalments spread from 25 September to 28 December 2026 for the 2025 season. Balances of EUR 300 or less are withdrawn in one go.

If the return shows that too much was withheld, the refund arrives by bank transfer, generally from the end of July or during August, sometimes even before the notice itself. The full refund and claim cycle is covered in our tax refund in France guide.

The 60% advance in January 2027

If you are entitled to recurring tax credits or reductions (home childcare, a home helper, donations, certain real estate investments), the tax office pays a 60% advance in mid-January 2027. It is based on the expenses declared in spring 2026 for 2025. The remaining 40% follows in summer 2027, once the final amounts are known.

The official example: EUR 2,000 of tax credit produces a EUR 1,200 advance in January. If your circumstances change and the advance would be too high, you can adjust or cancel it in the last quarter of 2026 from your personal space on impots.gouv.fr. In the first year of a new recurring expense, there is no advance: the full credit is paid the following summer.

Filing your annual return

The annual return is filed each spring. The online filing window opens in April, and deadlines run typically from late April to early June, set by department and by whether you file on paper or online. First-time filers in France receive a pre-filled return with salary and dividend data already reported by employers and banks.

Non-residents file the same core return, plus the specific forms for French-source income and any treaty claims. If the tax office owes you money after an error, an online claim from your personal space normally gets an answer within six months. The exact claim deadline is stated on your tax notice.

If you are a non-resident

Three specific rules apply when you live outside France but earn French income.

First, withholding takes a specific form. Salaries and pensions paid from France to a non-resident are subject to a dedicated withholding (RAS NR, retenue à la source spécifique non-résident). French rental income and sole-trader profit are typically collected through third-party instalments.

Second, your file is handled by a dedicated office, the SIPNR (Individual Tax Department for Non-Residents), for income tax matters after you leave France. Local property taxes remain with the local office.

Third, treaties matter more, not less. The rate you finally pay on French dividends or pensions can be set by the treaty between France and your country of residence. The return is where you claim it. For the wider picture of what else France taxes, read our tax in France overview.

How a chartered accountant helps

An accounting firm that works in both French and English keeps the mechanics above from becoming guesswork. GME Audit is led by Steeve Elharrar, chartered accountant (expert-comptable) and statutory auditor (commissaire aux comptes). The team cumulates more than 10 years of experience in accounting, audit and advisory, with Big Four backgrounds at KPMG and Deloitte, and handles about a hundred files each year.

Concretely: computing your bracket position before the year closes, checking household shares and the 10% allowance, and adjusting your withholding rate after an income change. The same work covers preparing the return and filing claims when the notice is wrong. Client accounting runs on Pennylane, so the figures behind your return are current rather than reconstructed at filing time.

Three questions we hear often

Is a 45% rate applied to all my income? No. The 45% rate only applies to the slice of taxable income above EUR 180,294 for a single person. Everything below is taxed at 0%, 11%, 30% and 41% slice by slice, so your effective rate is always lower than your top bracket.

Does my company pay income tax? Not if it is a SASU, SARL or SA. Those pay corporate income tax, and you pay income tax personally on the salary and dividends you take out. Sole traders and transparent structures are taxed directly through the personal return.

Can I file in English? The official filing forms and the impots.gouv.fr personal space are in French. English-speaking taxpayers commonly prepare their figures in English with an adviser, who then files in French and handles correspondence with the tax office.

Key points to remember

French income tax is progressive, with five brackets from 0% to 45% applied slice by slice. The tax household and its shares, the 10% professional allowance capped at EUR 14,426, and the decote shape the final bill. Since 2019 the tax is withheld at source, and the annual return settles the balance. Expect four instalments from 25 September to 28 December 2026, refunds from late July, and a 60% advance in mid-January 2027. Non-residents face a specific withholding regime and a dedicated office, the SIPNR.
