Understanding French Income Tax: What You Need to Know

The first and most important question is whether or not you are liable to pay income taxes in France. If you are legally resident in France, you must declare your global income on your annual French tax return, and you will be liable for French income tax on your earnings.

However, there are certain situations in which non-residents may also be liable for French income tax, or occasions where French residents may pay their income tax in a foreign country depending upon the double tax treaty between the countries concerned.

See our guide to Understanding French Tax – Are You Tax Resident in France?

For French residents, French income tax is levied on your global income, including earnings from employment, business ventures, or self-employment, as well as income from investments, savings interest, pensions, and property rentals. Before we look at French tax rates and allowances, there are a few things that you need to understand about how French income taxes are calculated.

Fiscal Household (Foyer fiscal)

In France, income tax is calculated based on your foyer fiscal (fiscal household), not for each individual taxpayer as in many countries. This means that if you are married or in a PACS civil partnership, you will file a joint tax return. Taxes are calculated based on the total income of your foyer fiscal (i.e. you and your partner’s income combined) and your quotient familial (i.e. the number of “parts” that make up your household, which depends on your family situation).

Put very simply, a family with dependent children will pay less tax than an individual or married couple with no children. If you are single, separated, or divorced, your foyer fiscal will be made up of yourself and any dependent children who live with you.

The quotient familial works by dividing your household’s total taxable income by the number of parts, applying the tax scale to the result, and then multiplying the resulting tax figure back up by the number of parts. A married couple counts as 2 parts; each of the first two children adds 0.5 parts; and each child from the third onwards adds 1 full part. The tax advantage per additional half-part is capped at €1,807 for the 2026 declaration (on 2025 income).

Income Tax and Social Charges

France is often called out for having high taxes, but it’s important to understand that the bulk of taxes levied on income comes from social charges (prélèvements sociaux or contributions sociales) rather than income tax. Income tax rates, starting at 11% after a tax-free allowance, can actually be much lower than those of other countries, especially when you factor in the quotient familial as explained above. However, the addition of social charges can make this initial figure misleading.

While this article looks solely at income tax, it is imperative to take into account both of these taxes to fully understand your income tax liabilities in France. For more on this, read our guide What You Need to Know About French Social Charges.

PAYE System

Since 2019, a Pay-As-You-Earn or prélèvement à la source system has been in place throughout France. This applies to all employment income, retirement income (state pensions and annuities), sick pay and maternity leave, and income from rental properties. A standard French payslip will detail the amount of both impôt sur le revenu (income tax) and charges sociales (social charges).

For those with overseas income such as pensions or rental income that is not subject to withholding at source, France collects the tax through quarterly acomptes (instalments) debited directly from your bank account, based on your most recent tax return.

Annual Tax Declarations

In France, every resident with their domicile fiscal in France must file an annual tax return. This is a legal requirement, and it is your responsibility to declare all of your global earnings, even if you have no tax to pay.

According to service-public.gouv.fr, online filing is now mandatory if your home is connected to the internet. The 2026 declaration (covering your 2025 income) opened on 9 April 2026. The deadline for paper returns is 19 May 2026. For online declarations, the deadline depends on which département you live in.

In France, the tax year runs from 1 January to 31 December, and you declare your previous year’s earnings in the spring of the following year. So in 2026, you are declaring your global income from 2025.

If you have previously filed online, much of your declaration will be pre-filled with information already known to the tax authorities (salaries, pensions, etc.). You should check this carefully and correct or complete it as needed.

France’s barème de l’impôt (tax scale) is set each year by the loi de finances. The 2026 barème was established by the loi de finances for 2026, adopted on 19 February 2026, which revalued the thresholds by 0.9% to account for inflation.

French Income Tax Rates 2026

The following rates apply to your 2025 income, declared on your 2026 tax return. The bands are applied per part of quotient familial:

• Up to €11,600: 0%
• From €11,601 to €29,579: 11%
• From €29,580 to €84,577: 30%
• From €84,578 to €181,917: 41%
• Above €181,917: 45%

The following example is taken from the French government website here.

The following example is adapted from service-public.gouv.fr.

For a single person (1 part) whose taxable net annual income is €30,000, the calculation is as follows:

• Up to €11,600 (band 1): €0
• From €11,601 to €29,579 (band 2): (€29,579 – €11,600) x 11% = €1,977.69
• From €29,580 to €30,000 (band 3): (€30,000 – €29,579) x 30% = €126.30
• Total tax: €2,103.99, or approximately 7.01% of net taxable income.

The décote (low-income tax reduction)

It is worth noting that for taxpayers with modest incomes, a mechanism called the décote can reduce or even eliminate the tax calculated under the barème. If your gross tax liability falls below a certain threshold, it is automatically reduced. This means that in practice, many people on low incomes pay little or no income tax even if their income falls within the 11% band.

The 10% abattement on salaries and pensions

Before the barème is applied, the tax authorities automatically deduct a 10% allowance from your declared salary or pension income to account for professional expenses or the costs of retirement. This reduces your taxable income before the tax bands are applied. The allowance is subject to an annual minimum and maximum, both of which are updated each year. For pensioners, this abatement is capped at €4,439 per household for the 2026 declaration (on 2025 income). Salaried workers may instead choose to deduct their actual professional expenses (frais réels) if these exceed the flat 10%.

Income Taxes for Businesses and Self-Employed Workers

It’s important to note that different tax rules may apply to businesses and self-employed workers, for example, those under the auto-entrepreneur scheme. It’s highly recommended to seek the advice of a registered accountant or international tax advisor if starting a business or setting up as a freelancer in France in order to fully understand your tax responsibilities and liabilities.

As previously mentioned, all French residents must fill in an annual tax declaration. Your annual declaration can be made online via the French tax website, and you can save and amend your declaration before deciding to submit it. Tax claims and requests for tax refunds or rebates can also be made online. Even after submitting, you can make corrections up until the filing deadline for your département.

The process is slightly different when you fill out your first tax return, and there are certain additions you may need to include if you have foreign savings, investments, or income to declare (notably formulaire 2047 for foreign income and formulaire 3916 for foreign bank accounts).
