The reason a French salary is confusing to a UK reader is that a French payslip carries THREE numbers that all get translated as net. SALAIRE BRUT is the gross. SALAIRE NET AVANT IMPÔT is what is left after social contributions, and it is the figure French people mean when they say their salary. NET À PAYER APRÈS IMPÔT is what actually arrives, after income tax withheld at source. The gap between the first two is the cotisations, and the gap between the second and third is the barème, which service-public.gouv.fr publishes and which this page works out exactly.
The barème a French tax calculator applies, and what it is charged on
France's progressive scale currently published applies to 2025 income and was set by the 2026 finance law: nothing up to €11,600, 11% from €11,601 to €29,579, 30% from €29,580 to €84,577, 41% from €84,578 to €181,917 and 45% above. It is charged on NET IMPOSABLE, which is roughly the salary after social contributions and after a 10% deduction for professional expenses, not on the gross. So a €40,000 net imposable pays €5,103.99, an effective 12.76%; €30,000 pays €2,103.99 and €60,000 pays €11,103.99.
The quotient familial, which has no UK equivalent
France taxes the HOUSEHOLD, not the person. The taxable income is divided by a number of parts, one for each adult and a half for each of the first two children, the barème is applied to the result, and the tax is multiplied back up. A couple with two children has three parts, so the same household income meets much lower bands than a single person's would. This is why a French tax calculator asks about your family before it asks about your salary, and why a figure worked out for a single person is the worst case rather than the typical one.
The cotisations, and why they are the bigger number
Social contributions come off the gross before any of the above, and they are larger than the income tax for most salaries: pension, unemployment, health, CSG and CRDS, at rates that depend on your status, your scheme and whether you are a cadre. That is why a French gross looks high against a UK one and the take-home does not. It is also why no honest single percentage can be quoted here: the rates are set per scheme rather than by one national table, and URSSAF publishes them. Your own payslip's brut-to-net gap is the only figure that is yours.
Prélèvement à la source
Since 2019 income tax is withheld from the payslip at a rate the tax office gives your employer, based on your last declaration, so the tax is no longer a bill that arrives a year late. Three consequences. Your net à payer changes when the rate changes, usually in September. A new arrival with no French declaration history is put on a default rate from a published grid, which frequently over-deducts. And the annual declaration still happens: it reconciles the withholding against the real liability, and repays or collects the difference.
Salary calculator France: reading a French offer from the UK
Ask which of the three numbers the offer is quoting, because "€45,000" as brut and as net avant impôt are very different jobs. Ask whether the salary is on 12 or 13 months, since a thirteenth month is common and changes the annual figure by 8.3%. And remember that residence, not the employer's address, decides which country taxes the salary; the UK and France have a double taxation agreement that prevents the same income being taxed twice, and the French tax year is the calendar year against the UK's 6 April to 5 April.
Questions people ask about france tax calculator
What is net imposable?
The figure French income tax is charged on: the salary after social contributions and after the 10% deduction for professional expenses. It is not the gross and it is not the net you are paid.
How much income tax on €40,000 in France?
€5,103.99 on €40,000 of net imposable for one part, an effective 12.76%, under the barème currently published for 2025 income. A household with more parts pays less on the same income.
Why is French gross so much higher than the net?
Social contributions, which are larger than the income tax for most salaries and come off before it. The rates vary by scheme and status, which is why no single percentage is honest.
Is income tax deducted from a French payslip?
Yes, since 2019, at a rate the tax office sets from your last declaration. The annual declaration still happens and reconciles the difference.
