How French income tax works
France taxes the foyer fiscal (tax household) as a unit. Your total taxable income is divided by your number of parts — 1 for a single person, 2 for a married or PACS couple, plus 0.5 per child for the first two children and 1 per child from the third — and the rate scale is applied to that per-part figure. The resulting tax is then multiplied back by the number of parts. This quotient familial system means a couple with children pays noticeably less than a single person on the same income.
The scale itself has five tranches. For the barème 2026 (Loi de finances 2026, applied to 2025 income, indexed +0.9%): 0% to €11,600 per part, 11% to €29,579, 30% to €84,577, 41% to €181,917, and 45% above. Low tax bills get an extra softening: the décote reduces gross tax below €1,982 (single) or €3,277 (couple) — décote = €897 − 45.25% × impôt brut for singles (€1,483 − 45.25% × brut for couples).
Note what this doesn't cover: France's social levies (CSG/CRDS, 17.2% on investment income) and employee social charges are separate from income tax, and since 2019 income tax is collected at source (prélèvement à la source) with an annual reconciliation — the calculator shows the annual liability the reconciliation targets.
Methodology
per-part income = household income ÷ parts
impôt brut = parts × (0% to €11,600 + 11% to €29,579 + 30% to €84,577 + 41% to €181,917 + 45% above), rounded to the euro
décote (if brut < €1,982 single / €3,277 couple) = €897 − 45.25% × brut (single) or €1,483 − 45.25% × brut (couple)
net tax = max(0, brut − décote)
Worked example
€50,000 taxable, single, no children (1 part): €11,600 × 0% = €0; €17,979 × 11% = €1,977.69; €20,421 × 30% = €6,126.30. Impôt brut ≈ €8,104 — effective rate 16.2%. Gross tax exceeds €1,982, so no décote. A married couple with two children (3 parts) on the same €50,000: per-part income €16,667 → per-part tax €557 → × 3 = €1,671 — less than a quarter of the single person's bill, showing the power of the quotient familial.
Frequently asked questions
Why "barème 2026" for 2025 income?
France names the scale for the year it's voted and paid in. The Loi de finances 2026 sets the barème applied to revenus 2025 — declared in spring 2026. So "2026 tax" in France always means "2025 income". This calculator follows that convention.
How do children change the calculation?
Each of the first two children adds half a part, the third and beyond add a full part each. More parts = lower per-part income = lower effective rate. (There are caps on the tax advantage per half-part, not modelled here.)
What is the décote exactly?
A reduction for small tax bills: if your gross tax is under €1,982 (single) or €3,277 (couple), you subtract €897 − 45.25% of gross tax (€1,483 − 45.25% for couples). It phases out naturally as gross tax approaches the threshold.
Does this include CSG and CRDS?
No. Social levies (notably 17.2% CSG/CRDS on investment income) and employee social-security contributions are separate from impôt sur le revenu and aren't included.
What about tax credits (crédits d'impôt)?
France has many — childcare, home employment, charitable giving — but they're personal and situational, so the calculator shows tax before credits. Your final bill is usually lower.
Are the 2026 tranches confirmed?
The barème 2026 figures (€11,600 / €29,579 / €84,577 / €181,917, +0.9% indexation, art. 197 CGI) are tied to the Loi de finances 2026. Beware pages still showing 2025 thresholds (11,497 / 29,315 / 83,823 / 180,294) mislabelled as 2026 — this calculator uses the indexed 2026 set.
