France: three different "net" figures on one payslip

A French payslip does not have one net figure, it has several, and they are all correct. Salaire brut is the headline. Take off the pension contributions, the complementary AGIRC-ARRCO pension, CSG and CRDS and you get net avant impot, the amount that used to land in your account. Take off the income tax withheld at source and you get net a payer, what actually arrives now.

The wrinkle is CSG. It is 9.20% of pay, but only 6.80% of it reduces your taxable income; the other 2.40%, plus the 0.50% CRDS, do not. So your net imposable is higher than your net pay, by exactly those two contributions. It is also charged on 98.25% of pay rather than on all of it, up to four times the social security ceiling, above which the abatement stops.

Income tax then runs on the quotient familial: your taxable income is divided by your number of parts, the barème is applied, and the result multiplied back. Children buy parts, but the advantage each half-part gives is capped, so beyond a point another child changes nothing. A décote wipes out small tax bills and tapers away at 45.25%, and anything under 61 euro is not collected at all. One cliff worth knowing: the CET contribution is charged on the whole of your pay, but only once you pass the ceiling, so it appears in full the moment you cross it.

Worked example: EUR 40,000, non-cadre, single, one part, 2026

Pension €2,920, complementary pension €1,604, and CSG with CRDS

€3,812.10 on a base of €39,300, which is 98.25% of pay.

After the 10% professional-expenses abatement of €3,280.36, taxable income is

€29,523. The barème gives €1,971.53, less a décote of €4.88.

Take-home: €29,696.90 a year, €2,474.74 a month. Your employer pays €11,168 on top, so the job costs €51,168.

  • France: cotisations salariales, CSG and CRDS, and the 2026 income tax barème

    Effective 2026-01-01 to 2026-12-31 · retrieved 2026-08-29

    Income tax is the bareme for 2026 as indexed by 0.9% by the loi de finances pour 2026 (loi n 2026-103 du 19 fevrier 2026, article 4). The PASS is 48,060 euro. Contribution rates are the 2026 figures for the regime general. The engine computes the annual income tax liability rather than the monthly prelevement a la source, because the withholding rate is set by the tax authority from a previous return and cannot be derived from a salary alone; the annual figure is what the year settles to. Not modelled: the prelevement a la source rate grids, which changed on 1 May 2026 and differ again for the overseas departments; frais reels in place of the 10% abatement; the contribution exceptionnelle and the contribution differentielle sur les hauts revenus, both of which are assessed annually rather than withheld and start above 250,000 euro of reference income; the reduction generale degressive on employer contributions, so the employer cost shown is the full rate; and the prevoyance and retraite supplementaire schemes, whose rates are set employer by employer. Complementary health cover is a user input rather than a rate, because the law requires the employer to offer and half-fund a scheme but sets no rate; the employee share is deducted from pay and, since 2014, is not deductible from taxable income, which is how it is treated here. Sources disagreed on the 10% abatement floor and ceiling: 495 and 14,171 euro circulate widely but are the 2023 figures, and 509 and 14,555 are the ones for 2025 income taxed in 2026.

    How we checked these figures

    No French authority publishes a gross-to-net table; impots.gouv.fr and URSSAF publish interactive simulators instead. The bareme is pinned to the worked example on service-public.gouv.fr, which takes 30,000 euro of net taxable income at one part to 2,103.99 euro of tax, with the full 11% bracket worth exactly 1,977.69. The decote parameters are cross-checked against their own algebraic break-even points, 897 / 0.4525 = 1,982 and 1,483 / 0.4525 = 3,277, both of which the published ceilings match. Contribution rates could not be read from urssaf.fr, which refused connections, so AGIRC-ARRCO rates come from the federation's own schedule and the social security rates from LegiSocial's reproduction of the 2026 URSSAF table; they are unchanged from 2025 in every source consulted.
