Micro-business 2026: accounting, VAT and tax

Updated March 2026 - The French micro-business regime is attractive because it is simple, but it does not mean there is no bookkeeping and no tax discipline. In 2026, a micro-entrepreneur still has to comply with record-keeping obligations, monitor VAT exposure and understand how the simplified income tax regime works. The risk is not heavy technical accounting. It is neglecting obligations that look light until a tax audit, bank request or growth phase makes them important.

Receipts ledger

Revenue must be recorded chronologically with the relevant details:

• ▸date;
• ▸origin of the receipt;
• ▸amount;
• ▸payment method;
• ▸reference to the supporting document.

Purchases register

This register is required in certain activities, especially where the business buys goods for resale, sells food to be consumed on site or provides accommodation.

Retention of supporting documents

Invoices, registers and supporting documents must be kept for the legal retention period. This point is often underestimated even though it matters a great deal during audits or financing discussions.

Many micro-business owners assume VAT will never concern them. That is not correct. As soon as turnover approaches the thresholds, invoicing patterns change, or specific operations are carried out, VAT becomes a central issue again.

In principle, the micro-entrepreneur benefits from a simplified method of calculating taxable income, based on a flat-rate allowance linked to the type of activity. Depending on the case, the option for the discharge payment regime may also need to be reviewed.

The real questions are not only "how much tax will I pay?" but also:

• ▸does the regime still fit my turnover level?
• ▸am I better off staying under micro if my costs are increasing?
• ▸am I approaching a move to the real regime?

• ▸failing to keep the registers up to date;
• ▸forgetting mandatory invoice details;
• ▸assuming VAT will never apply;
• ▸staying in micro when the real regime would be more efficient.

Hayot Expertise insight: the micro-business regime is excellent when launching an activity. It becomes less relevant as overheads, investment needs or B2B exposure grow.

The micro regime often becomes too narrow when:

• ▸turnover exceeds the thresholds;
• ▸business expenses become significant;
• ▸staff are hired;
• ▸a more credible structure is needed to grow.
