Special BNC regime in 2026: how does it work in practice?

Updated March 2026 - The special BNC regime, also known as micro-BNC or the simplified BNC regime, remains the natural entry point for many independent professionals. In practice, however, the real question is not just whether you can use it, but whether it still makes sense once your expenses, VAT and filing obligations are taken into account.

The special BNC regime allows you to report your receipts with relatively light formalities. The tax administration then applies a 34% flat allowance to determine the taxable base, with a minimum allowance of EUR 305.

In 2026, according to Entreprendre.Service-Public, the micro-BNC regime may apply if 2024 or 2025 turnover did not exceed EUR 83,600. If the threshold is exceeded over two consecutive years, the business exits the regime.

For related reading, see also our guides on the BNC filing sheet, accounting for liberal professions and micro-business accounting in 2026.

The regime targets activities taxed under non-commercial profits:

• ▸non-commercial liberal professions;
• ▸independent intellectual services;
• ▸certain regulated liberal professions;
• ▸micro-entrepreneurs taxed under micro-BNC.

Micro-BNC or controlled declaration?

Micro-BNC is often suitable if:

• ▸your expenses remain limited;
• ▸you are starting out;
• ▸you want light administrative management.

The controlled declaration often becomes more relevant if:

• ▸you have significant real expenses;
• ▸you depreciate equipment or pay substantial rent;
• ▸you want a more precise accounting view.

Hayot Expertise insight: the right choice is not based on the threshold alone. You need to compare the 34% allowance with your real expenses and then measure the combined impact on income tax, social charges and cash flow.

You declare your cash receipts, the administration applies the 34% allowance, and the remainder is then taxed under the personal income tax scale.

A key point to remember is that if your real expenses exceed 34%, the micro-BNC regime may become less favourable than the controlled declaration.

Under the special BNC regime, you do not file the 2035 package required under the real regime. However, you still need to:

• ▸keep a reliable receipts book;
• ▸report income through form 2042-C-PRO;
• ▸monitor your VAT position if you are inside or outside the exemption threshold;
• ▸verify each year that you still remain within the turnover limits.

If you want to leave micro-BNC, Entreprendre.Service-Public also reminds taxpayers that an option for the controlled declaration can be filed with the tax office.

The best regime is not always the simplest-looking one. It is the one that remains coherent once your expenses, your VAT situation and your operating reality are taken into account.

The special BNC regime remains very effective in 2026 for getting started quickly and reducing administrative weight. But it is only optimal if your real costs stay below the 34% allowance and if your tax organisation is monitored carefully.
