**Quick answer:** Between the 15th and 24th of the month after the period. The exact day is set for each company and shown in its espace professionnel. AccountsOS seeds the 15th so a return is never late.

## Detailed explanation

## The window

The CA3 is filed between the 15th and 24th of the month following the period. Your own date is in your espace professionnel on impots.gouv.fr.

## Monthly or quarterly

At the réel normal the CA3 is monthly, or quarterly when the annual VAT due is under EUR 4,000. From 1 January 2027 the simplified regime ends, and every business that is not in the franchise en base files the CA3, quarterly by default when prior-year turnover is up to EUR 1 million and current-year turnover is up to EUR 1.1 million.

## Filing and payment

Filing and payment are electronic and compulsory. Payment is by SEPA B2B direct debit, available once the return is validated.

## How Finn helps

Finn prepares the CA3 figures and sets the deadline on the 15th. The company or its expert-comptable files the return.
