What is a tax return? Definition

The tax package is a set of documents drawn up by the company or its chartered accountant at the end of each accounting period, in order to declare to the tax authorities the income it has generated.

It includes the annual financial statements, such as the balance sheet and income statement, and is mandatory for (almost) all companies.

  • 🤔 What about tax returns for micro-businesses? They are not required to do so.
  • 🤔 And what about tax returns for associations? The majority of them are not required to keep accounts, although there are a few exceptions.

It is used to communicate the company's financial situation, in a regulated manner, and must be sent to the tax authorities:

  • to calculate the amount of tax due,

  • and to check compliance with regulations.

  • pre-filling of amounts subject to income tax, thanks to the integration of new headings,
  • the tax reduction for sponsorship is now completed in a special appendix,
  • self-employed workers must now report their social security information on the BIC/IS form (as the Déclaration sociale des indépendants will disappear in 2021).

As for 2021, the new features concern :

  • the submission of tax returns for 2021, as detailed below,
  • the 2021 tax form, to be submitted from April 1, 2021 (at 0:00 a.m.),
