You are planning a move to France and want to know when the French tax office starts treating you as one of its own. After this guide, you will know the residence tests, the paperwork in the right order, and what your first French tax year really costs.

France tax residency for newcomers in 2026: the key figures

What changed for 2026

• Higher social levies on investment income. The 2026 Social Security Financing Act (law no. 2025-1403 of 30 December 2025, art. 12) raised CSG to 10.6% on most investment income. The total is now 18.6% instead of 17.2%. Rental income, property gains and life insurance stay at 17.2%.
• Indexed income tax brackets. The Finance Law for 2026 set the scale for 2025 income, with the 45% band starting above EUR 181,917.
• Treaty override now written into the Tax Code (since February 2025). Since 16 February 2025, article 4 B states that you are not French domiciled if a tax treaty makes you resident elsewhere (law no. 2025-127, art. 83). The version in force until 15 February 2025 had no such sentence.

Is this guide for you?

Read on if you…

• are moving to France as a freelancer, remote employee or founder in 2026 or 2027;
• want to know from which day France taxes your worldwide income;
• need a clear checklist for registration, health cover and your first French return.

Probably not your case if you…

• spend a few weeks a year in France while your home, family and work stay elsewhere;
• are leaving France. Read the guide to ceasing your tax residency in France instead.

When do you become a French tax resident?

France has its own definition of tax domicile in article 4 B of the Code général des impôts (CGI, General Tax Code). You are French resident if at least one of these tests applies.

Here's the catch. One test is enough. Someone who works mostly abroad but whose partner and children live in Lyon is French resident. The Service-Public guidance on tax domicile counts your partner and children in the household, not your parents or siblings.

When a treaty overrides the French tests

If your previous country still claims you, the tax treaty decides. Its tie-breaker (the rule that picks one country) checks, in order: permanent home, centre of vital interests (where your personal and economic ties are closest), habitual abode, then nationality. Article 4(2) of the France–Portugal treaty is a typical example. The guide to French tax residency rules covers these tests in depth.

When does French residence start in the year of arrival?

France has no split-year election to apply for. In practice, your arrival year is cut in two.

• Before your arrival date: only French-source income is taxable in France, if you had any.
• From your arrival date to 31 December: all your income, French and foreign, is taxable in France.

The impots.gouv.fr guidance for people arriving says to declare everything received from that date. If you had French income as a non-resident before arriving, the earlier part goes on form 2042-NR.

Your arrival date is the day the first test is met: the lease starts, your family moves in, or you start working from France. Keep proof of it.

Your move plan: before, during and after

Before the move

1. Check your right to stay. EU, EEA and Swiss citizens need no visa. Other nationals need a long-stay visa or residence permit, listed on Service-Public's residence permit page.
2. Plan your exit from your current country. Check its exit rules, such as an exit tax on shares. Leaving Malta or Austria? See how to cease tax residency in Malta or in Austria.
3. Check the impatriate regime if a French employer recruits you from abroad. Negotiate the package before signing.
4. Pick your business structure. Compare options in the guide to legal forms of business in France.

During the move

1. Sign a lease or buy a home. Your address anchors every registration.
2. Register your activity on the single business formalities portal if you work for yourself.
3. Open a French or SEPA bank account. Tax payments and direct debits need one.
4. Register for health cover. The universal health scheme (PUMa) covers people who work or live in France in a stable and regular way. Ameli may later ask you to prove 6 months of residence over the last 12.

After the move

1. List your foreign accounts. Every account held abroad must be declared on your return.
2. File your first return on paper. Without an online account, you cannot file online. Send form 2042 to the tax office (SIP) of your new home.
3. Add foreign income on form 2047 and carry it over to form 2042.
4. Claim any special regime on that first return, if you qualify.

How is your first French tax year taxed?

France taxes you as a resident from the day you arrive. You declare your 2026 income in spring 2027; the tax office publishes the exact dates when the campaign opens.

Income tax uses a progressive scale and a family quotient: your income is divided into "parts" according to household size. A single person has one part. The guide to personal deductions and benefits in France explains the parts and credits.

Withholding at source starts with your first French payslip or pension. Without a filing history, the tax office applies a non-personalised (default) rate that ignores your family situation, according to Service-Public. Your first return then sets your personalised rate.

Investment income is treated separately. In 2026, gains on shares are taxed at a flat 31.4%: 12.8% income tax plus 18.6% social levies. You can opt for the scale instead if it is cheaper. The capital gains tax guide for France has the details.

Good news on wealth tax: newcomers who lived abroad for the 5 previous calendar years pay IFI only on French property for 5 years.

What does the French impatriate regime offer?

The impatriate regime in article 155 B CGI targets employees recruited from abroad by a French company, or seconded to France by a foreign group. You must not have been French domiciled in the five calendar years before taking up the job.

• Exempt move-related pay: pay elements directly linked to your impatriation are exempt. Instead, you can opt to exempt a flat 30% of your pay.
• Cap: you choose between a cap of 50% of total pay on all exemptions, or 20% of taxable pay on the part linked to work abroad.
• 50% exemption of certain foreign investment income and gains, when paid from a country whose treaty with France has an administrative assistance clause.
• Duration: until 31 December of the eighth calendar year after the year you take up the job.

Honestly? Most freelancers working for foreign clients will not qualify, because the regime is built around a job in France. The guide to tax incentives for expats and digital nomads in France covers the other options.

Which treaty protects you during the switch?

The treaty with your previous country decides who taxes income earned around the move date; France publishes every treaty on its international treaties page. Moving from Malta or Austria? Compare with how to obtain tax residency in Malta and in Austria. The overview of France's international tax treaties explains how relief works.

Common mistakes (and what they cost)

• Assuming you are not resident until day 183 → France taxes your worldwide income from your arrival date, and late tax adds penalties.
• Forgetting to declare foreign bank accounts → a fine of EUR 1,500 per account, or EUR 10,000 per account where the country has no anti-fraud assistance agreement with France.
• Leaving your old country's residence open by mistake → two countries claim you, and you rely on the treaty tie-breaker to avoid double tax.
• Waiting for an online account before filing → first-time filers must file on paper; a late return triggers penalties.
• Keeping share gains on the flat tax without checking → at 31.4% in 2026, the scale may be cheaper in a low-income first year.

Frequently asked questions

How long do I need to live in France to become tax resident?

There is no minimum stay. You become resident as soon as one test of article 4 B CGI applies: household or main place of stay, main professional activity or centre of economic interests. Staying 183 days or more makes France your main place of stay. But moving your family or your work to France makes you resident from that day.

Do I pay French tax on income earned before I arrived?

No. In the arrival year, France taxes your worldwide income only from the date you became resident. Income earned before that date is taxable in France only if it has a French source, such as French rent. Your previous country normally taxes the earlier part of the year, so keep proof of your arrival date.

How do I file my first French tax return?

If you have never filed in France, you cannot file online. Send form 2042 on paper to the tax office (SIP) of your new home, with form 2047 for foreign income. Once your file exists, you can create your online account and file online in later years.

Does France tax my foreign property and investments?

Yes, once you are resident, foreign income such as dividends and rent is taxable in France, with treaty relief for tax paid abroad. For the real-estate wealth tax (IFI), newcomers not French domiciled in the previous 5 calendar years are taxed only on French property for 5 years. The threshold is EUR 1.3 million net.

What is the French impatriate regime?

It is a regime in article 155 B CGI for employees recruited from abroad or seconded to a French company. Until the end of the eighth calendar year after starting the job, pay linked to the move (or a flat 30% of pay) is exempt, within a 50% or 20% cap, and half of certain foreign investment income is exempt. You must not have been French domiciled in the five previous calendar years.

When do I file my first French tax return after moving in 2026?

In spring 2027, when the campaign for 2026 income runs; the exact dates are announced by the tax office. Your deadline depends on how you file and where you live. Withholding at source applies from your first French payslip, at a default rate until your first return gives the tax office your real situation.
