Since France's B2B e-invoicing mandate took effect on 1 September 2026, one phrase keeps appearing in advisory articles and social posts: "grace period." It is comforting. It is also wrong — and believing it could cost your business real money.
The accurate position, per DGFiP's own practical guide (11 July 2026): the start date has not moved, no statutory grace period exists, and leniency is administrative, individual, and conditional on documented effort.
What the tax authority actually published
DGFiP's guide for businesses that were not ready on 1 September says four things clearly:
- The deadline stands. Every business in France must be able to receive e-invoices via an approved platform (plateforme agréée) since 1 September 2026.
- Penalties are not automatic — but they are not waived either. DGFiP assesses each business individually and expects documented evidence of genuine effort: platform quotes, a signed contract, a migration plan. A business that made no effort at all can be penalised immediately.
- The 3-month formal notice (mise en demeure) is narrow. It applies before fines only to the obligation to use an approved platform to receive invoices. It does not cover failing to issue e-invoices, and it does not cover e-reporting.
- Paper/PDF workarounds must be regularised. If technical problems forced you onto paper or PDF invoices, you are expected to push those invoices back through your platform once fixed — carefully, to avoid double payment or double VAT deduction — and to document what happened.
What to do this week
- If you have no approved platform yet: get quotes and sign — the paperwork itself is your protection.
- Create a simple "compliance effort" file: dates, quotes, contracts, vendor emails. If DGFiP asks, you answer in minutes.
- Do not rely on the mise en demeure for issuing or e-reporting obligations — it does not apply to them.
Why the confusion? Some commentary described the guide as a grace period; other commentary said the Finance Bill removed any grace period. Both describe the same reality loosely. The primary source — DGFiP's guide — is the version that counts.
