Compliance deadlines

The regulatory dates that change what your files must contain — and how long you have left.

Compliance deadlines

Two regulatory deadlines currently change what a financial file must contain: France makes e-invoicing mandatory on 1 September 2026 — reception for every business, issuing for large and mid-sized companies — and SEPA requires structured addresses on payments from 15 November 2026. ValidateFin publishes a checklist for each, and a free browser-based validator that proves a real file is ready.

A deadline only matters if your files are ready for it. Each page below states exactly who is affected, what changes on the day, what happens if you are not ready, and a checklist to get there — then hands you the validator that proves a real file passes. Nothing is uploaded: every validator runs in your browser.
