Welcome to France, where the croissants are buttery and the tax numbers are—well, essential.

You can’t avoid taxes, even in a country that’s more famous for wine than W-2s.

This guide is your golden ticket to understanding how to get your French tax number, without any of the bureaucratic tango.

Tax Identification Number (TIN)

For Individuals

The French tax authorities issue all individuals with a tax obligation in France a tax identification number.

This TIN is provided when the individual registers in the French tax administration’s databases.

This number is one-of-a-kind, dependable, and unchangeable. The TIN is also known as the numéro fiscal de référence or numéro SPI in French.

For Entities

The French entities (and all individuals carrying out business activities) are assigned an identification number by a governmental authority as soon as they are created.

This number is used for a variety of purposes, including taxation. This is known as the SIREN numéro.

Financial institutions include FCP (Fonds communs de placement) and SICAV (SociĂ©tĂ©s d’investissement Ă  capital variable). FCP does not have a tax ID number. In any case, the collection of a tax identification number is not required for FI entities.

Where To Find TINs?

For Individuals

On official identification documents, the French TIN does not appear (such as an ID card or passport).

It is on the first page of the pre-filled income tax return (dĂ©claration prĂ©-remplie d’impĂŽt sur le revenu) and the first page of the notice of assessment (known as Avis d’imposition) of residence tax, income tax, or property tax.

So, a pre-filled tax return or a notice of assessment may be associated with multiple people. In this case, the TIN of each taxpayer is listed in the exact order as the information in the document’s “Etat civil” field.

Why Is It Recommended To Apply For A Tax Number?

You can register for the online tax portal, submit your French tax return, pay your taxes online, and manage your withholding tax rate if you have a tax number.

A new PAYE tax system was introduced in France on January 1, 2019. The new withholding tax (PrélÚvement à la source) aims to close the one-year gap between income collection and tax payment on that income.

This means that income tax is now deducted from your paycheck every month. However, you must still file an income tax return each year for the income you received during the previous full calendar year.

The income tax return is also used to calculate the local residence tax (Taxe d’habitation) that you must pay if you own or rent your home and determine whether you must pay the television license fee (Contribution à l’audiovisuel public).

Tax returns are only submitted once a year. Tax filing season typically occurs between mid-April and early June.

Online filers have an extended filing deadline, and the deadline for submitting tax returns to the French tax authorities varies by département.

Online Filing

Tax returns must now be filed online, but there are some exceptions. For example, if you have never filed a French income tax return, you can obtain a paper copy online or from your local tax office.

To make an online declaration, go to website and log in to your personal account.

You can file your tax return online if you meet the following criteria.

Filing Deadlines :

Tax returns must be filed in May or early June of the year following the year of earning the income. Tax return deadlines are announced in April, and it is the responsibility of the person (taxpayer) to find out when they are and to meet them.

Who Must File An Income Tax Return?

There are several situations in which you must send a tax declaration:

  • You earn money from a French source.
  • Unless it is a minor activity, you have a professional activity in France, whether salaried or unpaid.
  • Your country of residence is France (for more than 183 days a year)

Failure to file a tax return will result in sanctions, and late filing will result in penalties.

  • If you have completed an internship, you are not required to declare income, known as indemnitĂ©s de stage, that is less than € 18,255*.

Tax Treaties :

France has signed tax treaties with a number of countries in order to resolve specific cases and/or avoid double taxation. A bilateral tax agreement between your previous country of tax residence and France may cover your income as a researcher.

  • A tax treaty is in effect if you clearly mention your case.

Housing Tax

Whether you own or rent, you must pay a tax called taxe d’habitation on your primary and secondary residences.

The housing tax is a tax levied to benefit local governments.

It varies depending on the municipality, the characteristics of your accommodation (size, number of rooms, etc.), and your personal situation (household income, the composition of the household, etc.).

The housing tax is calculated based on your situation on January 1 of each tax year.
