Many newcomers think tax residency in France starts after 183 days, as in the stereotypes. The reality is more subtle, and it works in both directions: you can be a French tax resident from the day you arrive, and you can be one even if you only spend part of the year here. Understanding the rule early saves you from expensive surprises.
Who gets tax residency in France?
French law (article 4 B of the General Tax Code) retains three criteria, and one is enough:
- Home or main place of stay. You have your home, or the place of your main stay, in France. The official doctrine says that a stay of more than six months in a year is generally treated as the main stay, but the notion of home, where you normally live with your family, comes first.
- Professional activity. You carry out your professional activity in France, as an employee or not, unless it is ancillary. If you have several activities, the one that takes the most time counts.
- Centre of economic interests. The place of your main investments, the seat of your business or where your assets are managed.
This is why "183 days" is only a rule of thumb. If you move with your family in September, you are resident on arrival. If your old country also considers you resident, the tax treaty between the two states settles the case. France has such treaties with all EU members, the UK and Switzerland. Tell your former country's tax office that you have left, because each has its own procedure to end residence.
How much income tax follows tax residency in France?
A French tax resident is taxed on worldwide income, under a progressive scale from 0% to 45%. For the 2026 return on 2025 income, per share of the family quotient, the scale is: 0% up to €11,600; 11% from €11,601 to €29,579; 30% from €29,580 to €84,577; 41% from €84,578 to €181,917; 45% above (Service-Public, verified 15 April 2026). A single person has one share, a married or civil-partnered couple has two, and children add shares, with a cap on the benefit.
Local taxes are separate. The taxe d'habitation on main residences was abolished on 1 January 2023. The taxe foncière remains for owners, and the taxe d'habitation still applies to second homes.
How does withholding tax work in France?
Since 2019, income tax on salaries is withheld at source by your employer. When you start, the administration does not know your income, so your employer applies a default rate from an official grid. In mainland France, the grid in force since 1 May 2026 gives 0% under €1,635 of monthly base and up to 43% at the top. You still must file an annual return. The deduction is only an advance.
Once you have an online account (after your first return), you can ask for a rate based on your estimated income, which avoids paying too much with the default one. Details of the first return are in how to get your French tax number.
What do you declare in your first French tax return?
The official page "I am coming or returning to France" says you declare income received from the day of your return to 31 December of the year of arrival, on form 2042 with relevant annexes (2047 for foreign income, 2044 for rents). It is filed in the spring after your arrival. The two official pages on first returns do not say quite the same thing; the more recent one says you can file online from the first time, once you have your online credentials (sent by post, or after your tax office has checked your identity). Otherwise the paper form 2042 goes to the tax office (SIP) for your address. Your foreign income, foreign bank accounts and property abroad must be declared.
The treaty between France and your old country decides who taxes each kind of income. Often France gives a tax credit equal either to the foreign tax or to the French tax on that income, or counts it only to fix your rate (the "effective rate" method). Read the article on "pensions", "dividends" or "employment" in your treaty.
What is the French impatriate regime?
If a French employer hires you from abroad, the régime des impatriés (article 155 B of the General Tax Code) can lower your income tax significantly. According to impots.gouv.fr:
- You must have been tax resident outside France during the five civil years before your start, and move your tax home to France. People who came on their own initiative are excluded.
- The regime runs until 31 December of the eighth year after the year you start. It stops if you leave the employer, but continues after a move within the same group.
- The impatriation premium is exempt if it is written in the contract, or in an amendment signed before you start. As an alternative, you can opt for a flat 30% of your net pay.
- Part of the pay for work abroad is exempt, within caps (50% of total pay, or 20% for that part alone), and 50% of some foreign investment income and gains are exempt.
Your remaining pay must be at least equal to the reference pay of comparable roles. Ask your employer to put it in writing before you sign. A separate rule, not part of this regime, helps any newcomer who was not tax resident in France in the previous five years: the wealth tax on property (IFI) covers only French property until the end of the fifth year after arrival. Working conditions are in working in France.
What about cross-border workers, retirees and the overseas departments?
Cross-border workers follow their own rules, which depend on the country of employment: Switzerland (outside Geneva), Germany, Italy and Spain still have a cross-border regime, Belgium no longer opens it to newcomers and Luxembourg has none. Pensioners have to read the pension article of their treaty, because some public pensions remain taxed by the paying state. For retirees, see how to retire in France. In Guadeloupe, Martinique and Réunion income tax is reduced by 30%, and in French Guiana and Mayotte by 40%, within caps (€2,450 and €4,050 for 2025 income). Saint-Martin, Saint-Barthélemy, French Polynesia and New Caledonia have their own tax rules, which this article does not cover.

What is the difference between a resident and a non-resident for French tax?
A resident is taxed in France on worldwide income. A non-resident is taxed only on French-source income, and files with the non-resident tax service. If you had French income before you arrived, such as rent from a flat you own, the period before your arrival goes on form 2042-NR and the period after on form 2042. A first-ever return as a new resident follows the rules described in our guide to the French tax number.
The first criterion looks at your home, meaning where you normally live with your family. If your partner and children stay in your old country, the question of where your home is becomes delicate, and the treaty may have to decide.
When are the tax deadlines in France?
They change every year. For the 2026 campaign on 2025 income, paper returns were due by 19 May 2026, and online returns between 21 May and 4 June 2026 depending on the department, with non-residents on the first date. The 2027 campaign, on 2026 income, starts in April 2027. A newcomer files the first return in the spring after arrival. Plan the paper form early, because the post takes time.
After you file, the tax notice arrives in the summer and sets your personal withholding rate. From then on you manage everything online. Withholding at source (prélèvement à la source) is only an advance: pay attention to the declaration of foreign bank accounts and property abroad, because mistakes there can cost more than the tax itself.
What should you do in your old country when you move?
Each country has its own procedure to end its tax residence: a departure declaration, a certificate of residence, a final return. Without that step, you risk staying taxable there. The France tax treaty with your former country will help only if both countries agree on where you live, which is why the paperwork on both sides must match. Keep your documents: the date you left, the lease or sale of your old home, and the contract of your French job.
Before you decide, have a tax adviser or a chartered accountant (expert-comptable) in France confirm your situation, especially if you have a business, a property abroad, a pension or a cross-border job. For the practical side of the move, use the moving to France checklist.
