What's Actually Changing?

The French government's e-invoicing reform affects every business operating in France. Here's the official timeline.

September 1, 2026

You must be able to receive e-invoices

No matter how small your business is - if you operate in France, you need to be set up to receive electronic invoices. Your larger suppliers will start sending invoices electronically through an official platform, not by email or PDF anymore. You need to be connected to receive them.

September 1, 2026

Big companies must also start sending e-invoices

Companies with more than 250 employees must start sending their invoices electronically. If you run a small business, you don't need to send e-invoices yet - you only need to receive them.

September 1, 2027

Everyone must send e-invoices too

Now it's your turn. Every small business, freelancer, and auto-entrepreneur must send invoices electronically. PDF invoices by email or paper invoices will no longer be accepted.

The Penalties Are Real

Non-compliance means financial penalties and increased scrutiny from French tax authorities.

50€
per non-compliant invoice
15 000€
annual penalty cap
Tax audits
increased risk for non-compliant businesses
