How do you get a French tax number and file your first tax return in 2026?

If DGFiP has already issued a French tax document, find the number at the top and use the identifiers shown to activate your personal account on impots.gouv.fr. If no number exists but you need online access for withholding or another tax matter, contact the service des impôts des particuliers, the local personal tax office for your home. It may verify your identity in person or through the site's secure contact process before assigning access.

Do not wait for an employer to create the full tax account. France's prélèvement à la source, meaning income-tax withholding at source, may begin through payroll, but annual reporting remains a separate reconciliation of household income and circumstances.

Check the filing instructions and deadline published for that year's campaign. DGFiP states that a person declaring French income or property assets for the first time may not have access to online filing and must use the standard paper forms downloaded from impots.gouv.fr. Form 2042 is the main individual income-tax return; foreign accounts, foreign income, property, and other items can require additional forms.

Send the signed package to the personal tax office responsible for the French main home. A genuine non-resident normally uses the non-resident service for taxable French-source items. Keep copies and proof of delivery. Do not send a first resident return automatically to the non-resident office merely because you lived abroad before moving.

Report the household position requested under French rules. Marriage, a French civil partnership, separation, dependants, and a spouse living abroad can change whether income is reported jointly or separately. If one spouse is French tax resident and the other is not, the result can be mixed and fact-specific.

No. French domestic tests consider your household or main home, principal professional activity, and centre of economic interests. Meeting one test can matter. If another country also treats you as resident, the applicable tax treaty can use tie-breaker rules.

A French tax resident can have to report worldwide income and foreign accounts, even where a treaty prevents double taxation or gives primary taxing rights elsewhere. A non-resident can still owe filing for French-source income. Cross-border remote work, foreign companies, pensions, investments, and split-resident couples deserve advice based on the relevant treaty.

DGFiP processes the return and issues the identifiers and tax assessment information needed for later online access. Check your name, birth details, address, household members, income, and withholding credit. Use secure messaging or contact the office promptly if something is missing.

Keep payslips, foreign income statements, bank-interest records, account details, treaty evidence, and the filed forms. The tax assessment is also commonly requested for French banking, housing, and administrative files.
