Declarations and social contributions
Advancing the September 2026 turnover reporting deadline for micro-entrepreneurs
Publié le 07 octobre 2026 - Entreprendre Service Public / (Prime Minister)
The September 2026 sales declaration or the 3e Quarter 2026 must be completed by Saturday, October 31, not November 2, 2026.
The micro-entrepreneur (or self-entrepreneur) must declare his turnover (₩), on a monthly or quarterly basis depending on the option chosen by the applicant. This approach allows the calculation of its social contributions and contributions.
FYI
The report must be made before the last day of the month or quarter following the reporting period (e.g. 30 April to report the month of March).
If the deadline is a Saturday, Sunday or public holiday, it is extended to Monday or the following day.
This year, October 31, 2026 is a Saturday but Urssaf has indicated that the deadline will not be extended to November 2.
Exceptionally, the September 2026 turnover declaration or the 3e quarter 2026 must therefore be carried out by Saturday 31 October 2026 at 11:59 p.m.
