Launch Biztax assessment year 2024


Need to file your corporate income tax, legal entities tax or non-resident corporation tax return? Biztax is now available for the assessment year 2024.


The filing deadline for returns with balance sheet dates from 31 December 2023 to 29 February 2024 is 30 September 2024.

If you file your return by 30 August 2024 at the latest and it gives rise to a refund, we will give it priority treatment. As a result, you will receive the refund, barring exceptions, no later than the end of December 2024.

New identification screen

Once logged into Biztax, you reach a new identification screen which directly displays your various possible profiles for:

  • icône citoyen either logging into in your own name
  • icône entreprise or on behalf of your company

Then click on the company on whose behalf you want to proceed.

You can only proceed in your own name?
If there is only one available profile, you are automatically redirected to Biztax without going through this identification screen.
