Of the neighbouring self-employed regimes out there, France’s is probably the easiest to explain to someone coming from Spain — and also the one hiding the most nuance once you actually start billing. The micro-entrepreneur regime (also called auto-entrepreneur, the name it launched under in 2009) replaces Spain’s fixed contribution with a system proportional to what you actually earn, with two separate thresholds that are rarely explained together clearly.
Two ceilings, not one
The micro-entrepreneur regime has a turnover ceiling (chiffre d’affaires) that in 2026 sits around €77,700 for services and liberal activities, and considerably higher for goods sales. Exceeding it for two consecutive years removes you from the regime. But there’s a second, independent threshold for VAT exemption (franchise en base de TVA): a base of €37,500 for services, extended up to €41,250. It’s entirely possible to remain a micro-entrepreneur while also having to start charging VAT on your invoices because you’ve crossed the second threshold without crossing the first — a combination that surprises anyone assuming «being in the regime» automatically means being VAT-free.
How it’s paid: proportional contributions, not a fixed fee
Unlike Spain’s RETA contribution, which is paid by bracket regardless of exact monthly income within that bracket, the micro-entrepreneur pays social contributions as a direct percentage of what’s actually billed and collected: around 25.8% for service activities. If you bill nothing in a given month, you pay no contribution that month — a huge structural difference from the Spanish system, where the fee is paid whether or not there was activity that period.
There’s also an option called versement libératoire, which lets you settle income tax as a fixed additional percentage on the same turnover, in the same payment as your social contributions, instead of declaring it separately at year-end under the general progressive scale. It isn’t advantageous for everyone — it depends on your household’s total income level — but it considerably simplifies management for those who choose it.
What changes in 2026: e-invoicing on the horizon
France is introducing mandatory e-invoicing from 1 September 2026 for most businesses, although for micro-entrepreneurs the obligation to issue e-invoices doesn’t kick in until 1 September 2027 — they will need to be able to receive them from 2026, though. It’s a structural change worth anticipating if you regularly bill French companies, regardless of when you’ll need to issue them yourself.
Auto-entrepreneur vs. Spanish autónomo, in practice
The clearest advantage of the French system for someone starting out with low or irregular income is paying nothing if you bill nothing, versus Spain’s fixed fee that runs from day one of registration regardless of actual activity. The downside shows up once turnover grows steadily: French contributions, being proportional with no relative cap, can end up weighing more in relative terms than a RETA fee that, past a certain income level, becomes comparatively more advantageous precisely because it’s fixed.
In the comments: if you bill as a micro-entrepreneur in France with clients in Spain or vice versa, share how you handle intra-EU VAT between the two countries and whether you’ve activated the versement libératoire. It’s the practical friction no guide sums up well.
