French Income Tax Brackets 2026: Rates, Calculation and Thresholds (2025 Income)

France's income tax is calculated on a progressive scale applied to 2025 income during the 2026 filing season. The 2026 Finance Act indexed the bracket thresholds upward by 0.9%, in line with inflation neutralisation policy. For business owners, directors, and high earners, understanding how the scale actually works — and where the key thresholds sit — is essential for making informed decisions on remuneration, dividends, and tax planning.

The five official brackets for 2026 (applied to 2025 income, per household share): 0% up to €11,600 ; 11% from €11,600 to €29,579 ; 30% from €29,579 to €84,577 ; 41% from €84,577 to €181,917 ; 45% above €181,917.

The French progressive income tax scale has five bands. It is not applied to gross household income directly. Instead, taxable income is divided by the number of household shares (quotient familial), the scale is applied to that figure per share, and the result is then multiplied back by the number of shares.

The +0.9% upward revision means the zero-rate threshold moved from €11,497 (for 2024 income) to €11,600 for 2025 income. Taxpayers whose income grew at less than 0.9% effectively pay slightly less in absolute terms.

The key misconception to dispel: reaching the 41% bracket does not mean 41% of total income is taxed. Only the portion of income above the lower threshold of that bracket is taxed at the higher rate. Every euro below that threshold is taxed at the applicable lower rate.

Four-step process:

1. Determine net taxable income after deductions (professional expenses — either standard 10% allowance or actual costs — and any allowable charges such as alimony paid).
2. Divide net taxable income by the household's number of shares (quotient familial).
3. Apply the progressive brackets to the per-share figure.
4. Multiply the resulting per-share tax by the number of shares to obtain gross tax.

Worked example: single taxpayer with €40,000 taxable income (1 share)#

A self-employed consultant, single, no dependants, with €40,000 net taxable income for 2025:

Marginal tax rate (TMI): 30%. Effective average rate: approximately 12.8% (€5,104 / €40,000). This gap between marginal and average rate matters for any remuneration decision: the additional cost of earning €1 more is 30 cents, but the overall burden is much lower.

The décote is an automatic tax reduction applied to lower-income taxpayers before the final tax bill is issued. No separate filing is required.

Eligibility thresholds for 2026 (2025 income):

• Single, divorced, widowed: gross tax up to €1,982
• Couple filing jointly: gross tax up to €3,277

Formula:

• Single: décote = €897 − (45.25% × gross tax)
• Couple: décote = €1,483 − (45.25% × gross tax)

If the formula produces a negative number, the décote is zero. The relief tapers off smoothly as gross tax approaches the threshold, avoiding a cliff effect.

The quotient familial is central to how France taxes households rather than individuals. It assigns a number of shares based on marital status and dependants:

• Single person, no dependants: 1 share
• Married or PACS couple, no children: 2 shares
• Each child at charge: generally an additional half-share

The cap on family quotient benefit#

To prevent the mechanism from conferring disproportionate advantages at high income levels, the tax reduction generated by each additional half-share is capped at €1,807 for 2026 (2025 income). This cap applies per demi-part, so a couple with two children (one extra full share = two half-shares) can save at most €3,614 in tax through the family mechanism.

Beyond a certain income level, the quotient familial no longer reduces tax further — the household is effectively treated as if those extra half-shares did not exist.

For directors of French companies (SASU, SARL, SAS) drawing a salary or management remuneration, the marginal rate on the last euro of taxable salary determines the cost of additional compensation. At €40,000 of taxable income per share, that rate is 30%. Above €84,577 per share, it becomes 41%.

For a single director with €100,000 of net taxable income (1 share), approximately €15,423 falls in the 41% bracket (€100,000 − €84,577). The effective average rate on that income will be well below 41%.

The comparison between salary (taxed at the progressive scale) and dividends (taxed at the 30% flat tax rate — the prélèvement forfaitaire unique, or PFU) depends entirely on the director's marginal rate. A director in the 30% bracket may find the flat tax advantageous on dividends; a director solidly in the 41% bracket almost certainly does, unless specific deductions apply.

Note: the LFSS 2026 raised the CSG component on certain capital income by 1.4 points, which modifies the effective overall rate on dividends in some scenarios. Always verify the current rate before modelling.
