What is the tax identification number?

The tax identification number (NIF) is a unique identifier used to conduct all your tax-related formalities. This 13-digit number is issued for life. It allows you be known and recognised by the authorities, to create your personal page online and to pay any dues and taxes you may owe, such as income tax, property or residence tax, radio & TV licence fee, etc.

Why apply for a tax identification number?

When you arrive in France, you are not known to the tax authorities. Up that point, you are therefore considered non-resident for tax purposes. This situation changes when you move to France for any length of time. You become resident for tax purposes if:
– Your main residence is in France and you reside there permanently (i.e. more than 6 months per year).
– You exercise a professional activity in France: this means your main profession, whether salaried or freelance.
– The focus of your economic interests lies in France (investments).

If you meet one of the foregoing conditions, your tax domicile (which has nothing to do with where you live) is situated in France: You are therefore liable for income tax in France. Now, the amount of tax depends as much on the income as on the family situation of the declaring party, which has an impacts on their reference tax income.

Therefore, when you apply for your tax identification number on arrival rather than when you submit your first tax return, you may immediately benefit from a rate of deduction at source which is appropriate to your personal situation. It’s in your own interests to apply for the number if you move to France with your family because it will allow you to benefit from certain tax and welfare breaks, as well as a lower rate of taxation than a person living alone.
