Frequently asked questions

When does electronic invoicing become mandatory?
Reception becomes mandatory for all businesses on September 1st, 2026. Issuance is mandatory from that date for large enterprises and mid-market companies, then on September 1st, 2027 for SMEs, micro-enterprises and self-employed workers.
Am I concerned if I am a self-employed worker?
Yes. Micro-enterprises must be able to receive electronic invoices from 2026 and issue their own from 2027, as long as they conduct B2B operations in France.
Does reception really concern everyone in 2026?
Yes. Regardless of size, any business subject to VAT must be able to receive electronic invoices from September 1st, 2026. This is the first unavoidable milestone of the reform.
Can the schedule still change?
The schedule has already been adjusted in the past. The dates for 2026 and 2027 are those currently set; it is prudent to follow the official communications from the tax administration.
What happens if I am not ready?
Being unable to receive or issue invoices in the required format can block your exchanges with your partners and expose you to sanctions. Planning ahead for your platform choice significantly reduces this risk.
