The status ofself-employedofficially called micro-enterpriseseduced by its simplicity. Streamlined accounting, rapid creation, simplified declarations… According to Urssaf, micro-entrepreneurs now represent more than half of business creations in France. But behind this success, some self-employed people sometimes discover too late that this regime can become penalizing when their business grows or their professional expenses increase sharply.
Because unlike a traditional company, social security contributions are calculated directly on the turnover collected, even when costs explode. For certain liberal professions covered by the micro-BNC, contributions now reach 25.6% of turnover in 2026. Above all, actual expenses cannot be deducted for their exact amount, which can significantly reduce the profitability of certain activities.
The real threshold is not always that set by the administration
Many independents believe that status only becomes problematic when they exceed the official micro regime limits. In 2026they remain fixed at 83,600 euros for the provision of services and liberal professions and 203,100 euros for commercial activities, according to data from the French administration.
But in practice, the real shift can occur much earlier. “The micro-enterprise regime can become tax disadvantageous when the real costs become significant: subcontracting, advertising, travel, equipment or software”, explains Virginia Lopes Gomes, tax lawyer.
The flat-rate deduction
The problem comes in particular from the flat-rate reduction applied by the administration: 34% in micro-BNC, 50% for certain micro-BIC services and 71% for sales activities. This allowance is supposed to cover all professional expenses, even when the actual costs are much higher.
Virginia Lopes Gomes takes the example of a consultant carrying out 80,000 euros of turnover with 32,000 euros real costs. After approximately 20,480 euros of social contributions, he has approximately 27,520 euros before income tax. However, despite this much lower real income, its taxation will be calculated on the basis of 52,800 euros after application of the flat-rate reduction.
VAT often becomes a turning point
The micro regime ceiling is not the only threshold to monitor. In 2026self-employed people do not charge VAT until 37,500 euros of turnover for the provision of services and 85,000 euros for commercial activities. Concretely, a self-employed person can therefore remain in a micro-enterprise while having to invoice VAT. For certain professionals working with individuals, this transition can become delicate: either prices increase by 20%or the margin decreases.
Another important limit: in micro-enterprises, professional expenses cannot be deducted for their actual amount. Conversely, in a real regime or via a company subject to corporate tax (IS), certain expenses such as rent, travel expenses, software, depreciation or subcontracting costs can be deducted under conditions.
Why do some freelancers leave micro-enterprises?
When the activity grows, some entrepreneurs switch to a SASU or a EURL in order to better manage their taxation. These structures make it possible to retain more cash in the company, finance investments or depreciate certain equipment.
“Many entrepreneurs maintain a status out of habit without comparing their situation with other regimes,” observes Virginia Lopes Gomes. Sometimes with significant consequences: contributions that are too high, higher taxes, lack of cash flow or a structure that has become unsuitable for the development of the activity.
