Micro-entreprise or company in 2026: which structure to choose
The micro-entreprise regime is popular for its simplicity, but it is not always the most advantageous option. Past a certain turnover, or once real expenses grow, a company subject to corporate tax can lower the overall tax bill. Here is how the two compare in 2026.
Two opposite tax logics
The micro-entreprise regime taxes turnover after a flat allowance, with no option to deduct actual expenses. A company subject to corporate tax (impôt sur les sociétés, IS) taxes real profit — turnover minus actual costs — then applies separate taxation on what the owner withdraws, as remuneration or dividends. The right choice depends on your real costs and the scale of your activity.
Micro-entreprise BNC: simplicity and a flat allowance
Under the micro-entreprise BNC regime (liberal professions), the tax authority applies a flat allowance of 34% on turnover received (minimum €305): only 66% of turnover is subject to progressive income tax. Alongside that, URSSAF social contributions amount to 21.1% of turnover received, unrelated to the expenses actually incurred. The regime remains available as long as turnover does not exceed €83,600 (the BNC and BIC-services ceiling for 2026).
- Flat allowance of 34% on turnover (BNC), minimum €305
- Social contributions of 21.1% of turnover received
- Turnover ceiling: €83,600 (BNC and BIC services)
- No deduction of real expenses: the allowance replaces them entirely
The company under corporate tax: SASU or EURL
A company subject to corporate tax pays 15% on profit up to €42,500 (conditions apply: turnover under €10M, capital at least 75% held by individuals, fully paid up), then 25% above that. The owner can then choose between remuneration (deductible from the company profit but subject to social charges) and dividends, taxed at the 31.4% flat tax (PFU). Unlike the micro-entreprise, a company deducts its real expenses before tax.
- Corporate tax at 15% up to €42,500 of profit, then 25% above
- Dividends taxed at the 31.4% flat tax, after corporate tax
- Deduction of real expenses, with no flat allowance
- A choice between remuneration and dividends for the payout
The tipping point
A company generally becomes attractive once real expenses significantly exceed the micro-entreprise flat allowance (34% of turnover under BNC), or once turnover approaches the €83,600 ceiling. For a low-cost activity with moderate turnover, the micro-entreprise usually remains lighter on contributions and admin. For a profitable activity with significant real costs — equipment, subcontracting, premises — a company lets you pay tax only on net profit, then optimise the payout between remuneration and dividends.
Frequently asked
- Can I switch from micro-entreprise to a company mid-year?
- Yes, but the switch involves setting up a new legal structure, transferring or contributing the business, and formalities such as registration, bookkeeping and VAT where applicable. Plan the timing with your accountant.
- Is a company always better past the micro ceiling?
- Not automatically. Above €83,600 of turnover, the micro-entreprise regime falls back to the régime réel, which changes the comparison. The right answer then mostly depends on the level of your real expenses and your remuneration strategy.
- Does the versement libératoire change the comparison?
- It can lower the income tax paid under micro-entreprise, subject to a reference income condition, which sometimes narrows the gap between the two regimes. See our dedicated article on the versement libératoire.
- What expenses are covered by the flat allowance?
- All of them: the micro-entreprise flat allowance replaces any deduction of real expenses, regardless of their actual amount. That is why a high-cost activity is structurally penalised under micro.
