fireplotThe full calculation, step by step
Most calculators give you one number and no explanation. Here is exactly how your figure above is built, in the order French payroll and the tax office apply it.
How your income fills the 2026 tax scale
French income tax is progressive. Only the slice of income inside each band is taxed at that band's rate. Here is how far your taxable income reaches.
Understanding a French payslip
Social contributions come first, about 22% of gross. Pension, health, unemployment and the CSG/CRDS levies are withheld by your employer. France is unusual in that part of the CSG is not deductible for income tax, which is why your taxable income is about 80.9% of gross rather than the 78% left in your account.
Then the 10% professional expense deduction. Every employee automatically gets a deduction of 10% of taxable income, capped at €14,426, without receipts. You can claim real expenses instead if they are higher.
Then the progressive scale, per household part. The scale runs 0%, 11%, 30%, 41% and 45%. France divides household income by the number of parts (1 for a single person, 2 for a couple) before applying the scale, which is the famous quotient familial. This calculator shows a single person, so one part.
Finally the decote softens small tax bills. If your computed tax is below €1,964, a discount of up to €889 shrinks it, which is why many modest salaries pay little or no income tax. Since 2019 the tax is withheld monthly at source (prelevement a la source), so your payslip already reflects it.

Accuracy and assumptions
Frequently asked questions
How is net salary calculated in France in 2026?
Employee social contributions of about 22% of gross come out first, including CSG and CRDS. Income tax is then computed on roughly 80.9% of gross (because part of the CSG is not deductible), minus a 10% professional expense deduction, through the progressive scale of 0% to 45%, softened by the decote for small tax amounts. The tax is withheld monthly at source.
What are the French tax bands for 2026?
Per household part: 0% up to 11,497 euros, 11% to 29,315 euros, 30% to 83,823 euros, 41% to 180,294 euros, and 45% above. A single person is one part, so these thresholds apply directly to their taxable income.
What is the difference between net pay and net taxable income?
Your account receives gross minus all contributions, about 78% of gross. But the tax office computes tax on net imposable, about 80.9% of gross, because 2.9 points of CSG/CRDS are not deductible. French payslips show both lines, which confuses almost everyone.
What is the quotient familial?
France taxes households, not individuals. Income is divided by the number of parts (2 for a married couple, more with children), the scale is applied to one part, and the result is multiplied back. This calculator shows a single person; couples and families generally pay noticeably less at the same income.
What is the decote?
A discount for small tax bills. If a single person's computed tax is under 1,964 euros, it is reduced by up to 889 euros minus 45.25% of the tax. The effect is that income tax phases in gently instead of hitting at full force just above the 0% band.
Which rates does this calculator use, and are they current?
It uses the 2026 scale (indexed thresholds of 11,497 to 180,294 euros), the standard 22% employee contribution wedge with the 80.9% taxable base, the 10% deduction capped at 14,426 euros, and the 2026 decote parameters. Rates are reviewed when the loi de finances is published.
