The key idea
Read the payslip in order: gross pay, employee contributions, net pay before income tax, taxable net pay, income-tax withholding, then the amount paid. Taxable net pay is the withholding base and may differ from what reaches your bank account.
Start with gross pay
Gross pay is remuneration before employee deductions. Check the period, base salary, bonuses and any overtime before comparing two payslips.
A French payslip also shows social contributions and several net amounts. Layouts vary, but these entries let you trace the route from gross pay to the amount transferred.

A bonus or absence can change one month’s gross pay without changing the base salary.
Move from gross to net before tax
Employee contributions fund social protection and pensions. Some use income bands or different assessment bases, so a single percentage of gross pay is only a rough shortcut.
Find the “net à payer avant impôt sur le revenu” line after the social deductions. Expense reimbursements, benefits, health cover and corrections can make simple subtraction unreliable. Finopact estimates the main standard contributions for French private-sector employees; it does not reproduce a full payslip.
Compare the calculator result with net before tax, then identify employer-specific items separately.
Separate taxable net pay from take-home pay
Taxable net pay is the base for French income-tax withholding. It may differ from net before tax because some contributions are not tax-deductible or some employer-provided benefits are taxable.
Withholding applies the relevant rate to taxable net pay. The amount paid is the sum after withholding and any other payslip adjustments. Do not simply apply the tax rate to net before tax.

- Net before tax: pay after social deductions.
- Taxable net pay: income-tax withholding base.
- Amount paid: what reaches the bank account after payslip adjustments.
Work through an illustration, not a rate table
In this deliberately simplified example, gross pay is €3,000 and assumed employee deductions are €650, giving €2,350 net before tax. Assume taxable net pay is €2,400 and the withholding rate is 5%. Tax withheld is €120; without other adjustments, take-home pay is €2,230.
The €50 gap between net before tax and taxable net pay is an illustrative assumption, not a general formula. Check the actual lines on your payslip and use your own withholding rate.
| Amount | Value |
|---|---|
| Gross pay | €3,000 |
| Assumed employee deductions | −€650 |
| Net before tax | €2,350 |
| Assumed taxable net pay | €2,400 |
| Withholding: 5% × €2,400 | −€120 |
| Amount paid | €2,230 |
Before you take the next step
- I compare payslips for the same period and bonus conditions.
- I distinguish net before tax from taxable net pay.
- I apply the withholding rate to taxable net pay.
- I treat the calculator as a limited private-sector estimate.
