Understanding income tax in France
The income tax (IR) is one of the main French taxes. It is calculated on income earned the previous year and has been withheld at source since 2019. Understanding how it works allows you to legally optimize your tax situation.
2026 progressive tax brackets
French income tax uses progressive tax brackets. This means only the portion of income exceeding a threshold is taxed at the higher rate:
- 0%: up to 11,497 EUR
- 11%: from 11,497 EUR to 29,315 EUR
- 30%: from 29,315 EUR to 83,823 EUR
- 41%: from 83,823 EUR to 180,294 EUR
- 45%: above 180,294 EUR
The family quotient
The family quotient divides taxable income by the number of household shares. This mechanism reduces tax for families:
- Single: 1 share
- Married couple/PACS: 2 shares
- 1st and 2nd child: +0.5 share each
- From 3rd child: +1 share each
- Single parent with children: +0.5 share additional
The 10% allowance
All employees automatically receive a flat 10% allowance on their taxable income, representing professional expenses. It is capped at 14,171 EUR and cannot be less than 495 EUR. This allowance directly reduces the tax base.
Common legal optimizations
Several mechanisms allow you to legally reduce your taxes:
- Retirement Savings Plan (PER): contributions are deductible from taxable income, reducing tax according to your marginal bracket
- Charitable donations: 66% to 75% of the donated amount becomes a tax credit
- Rental investment: Pinel and Denormandie schemes offer tax reductions
- Home employment: 50% of expenses qualify for a tax credit

Frequently asked questions about income tax
What is the marginal tax rate (TMI)?
The marginal tax rate is the rate applied to the highest bracket of your income. It determines the savings for each euro deducted (PER, donations...). For example, with a 30% marginal rate, each euro contributed to a PER saves you 30 cents in tax.
How does withholding tax work?
Since January 2019, tax is withheld monthly from your salary by your employer. The applied rate is personalized based on your last return. In September, this rate is recalculated. If you overpaid, you receive a refund. If you underpaid, an additional amount is requested.
What's the difference between a tax reduction and a tax credit?
A tax reduction decreases the tax owed but cannot create a refund (if tax is zero, you get nothing back). A tax credit is refunded even if you owe no tax. Donations give a reduction; home employment gives a credit.
How does the PER reduce my tax?
Contributions to a Retirement Savings Plan are deducted from your taxable income (within a ceiling limit). The tax savings equals your marginal rate: with a 30% rate, you save 30% of the amount contributed. Note: savings will be taxed upon withdrawal, but often at a lower rate (in retirement).
At what income level do you start paying taxes?
In 2026, a single person becomes taxable from about 17,200 EUR of net taxable income (before allowance). After the 10% allowance, the taxable income of 15,480 EUR exceeds the 11,497 EUR threshold. For a couple, the threshold is approximately 32,200 EUR.
Are overtime hours taxable?
Overtime hours benefit from an income tax exemption up to 7,500 EUR per year. Beyond this ceiling, they are taxed normally. This exemption is automatic and appears on your pre-filled return.
How do I declare property income?
Property income (rent) is added to your other income and taxed at progressive rates. Two schemes exist: micro-foncier (30% allowance if rent under 15,000 EUR/year) or actual expenses (deduction of real charges). The choice depends on your deductible expenses.
When and how to file your tax return?
The return is filed online at impots.gouv.fr between April and June (deadline varies by department). Your return is pre-filled with salaries and income known to the administration. You must verify and complete it with your reductions/credits and non-pre-filled income.
