Reader question: I need to make a 'biens immobiliers' property declaration but cannot find my numéro fiscal or password to get onto the tax website. What can I do?

Your French numéro fiscal (tax number) will have been allocated when you became known to the tax system, either through paying income tax or local property tax.

Notably, it allows you to access your online tax space, where most people with income to declare to France now complete this annual formality. It is also where homeowners have to complete the new property ownership and usage form before June 30, 2023.

In the past, The Connexion has written about how to get a numéro fiscal to access the site if you do not have one.

However, if you already have a numéro fiscal and password for your tax space but cannot find or remember them there are simple solutions.

Where can I find my numéro fiscal?

The first thing to do is check your tax documents for your numéro fiscal.

They are shown at the top of all of your avis d’impôt tax statements, notably, whether for income tax or taxe d’habitation or foncière.

The number does not change, so even your oldest documents will have the correct figure.

It is a good idea to keep official documents you receive in France filed for future use, and any relating to tax should be kept at least three years.

Failing this, it is possible to have your numéro fiscal emailed to you.

Go onto the French tax website – – and in the top right click on votre espace particulier. On the right-hand side of the screen, you will see a button saying où trouver mon numéro fiscal ?

Click on this, then the recevoir votre numéro fiscal par courriel button to have the number sent to you via email.

Alternatively, it is possible to contact the tax authorities via telephone (0809 401 401 if in France) and ask them to confirm it for you.

If you can provide them with your information (name, address, date of birth etc), they will provide you with your numéro fiscal.

What about my password?

If you have forgotten your password, you can reset it, but to do this you need to have your numéro fiscal to hand.

On the tax site, in the same votre espace particulier section where you go to log on, fill in the section with your numéro fiscal, which will take you to the stage where you enter your password.

On the right hand side, there will be a button that says Vous avez oublié votre mot de passe. Click this, then Vous pouvez renouveler votre mot de passe en quelques clics.

You will then have to re-enter your numéro fiscal and date of birth and complete a Captcha image.

A code will then be sent to your mobile phone. You must enter this code in the required field on your computer (if you do not receive the code, you can click je n’ai pas reçu le code).

After this, you will receive an email link allowing you to reset your password. Clicking on this link will take you to a new page, where you have to enter your numéro fiscal and then your new password two times, then click confirmer.

After this, you will be able to log on using the tax website with your new password.

I have a numéro fiscal but no password, what should I do?

This situation can arise when you have not set up an online tax space before, either because you file your tax returns via paper declarations, or you are a second-home owner who has never needed access to the space.

In the case of the former, if you enter your numéro fiscal on the tax site, you will be prompted to input either your numéro d’accès en ligne, or revenu fiscal de référence to create your account (and subsequently a password).

Both of these numbers can be found on the first page of your last income tax return.

For the latter, you will need to circumvent the online space to create your account - you should follow the information on our article for second-home owners and the biens immobiliers form here that explains how to do this.
