Tool
Flat-rate calculator
Check whether you stay in the flat-rate regime and how much room is left before the VAT threshold.
The tool is indicative and tracks turnover limits. Trade, hospitality, advertising, finance, real estate and accounting generally cannot be flat-rate taxed. We confirm your exact status and amount for your activity.
Flat-rate limits and obligations in 2026
An entrepreneur can stay in the flat-rate regime while annual turnover does not exceed 6,000,000 dinars. Turnover is tracked through issued invoices and the KPO book (record of turnover), the only record a flat-rate entrepreneur keeps.
VAT registration becomes mandatory once turnover in any 365 consecutive days exceeds 8,000,000 dinars. That is a different threshold from the calendar flat-rate limit, so both matter.
The exact monthly tax and contributions are not chosen by the entrepreneur, they are set by a Tax Administration decision, based on the average wage and coefficients for activity, zone and years since registration. This tool checks the limits, and we give you the exact amount after a short consultation.
Let us keep your flat-rate booksFrequently asked questions
What is the turnover limit for flat-rate entrepreneurs?
An entrepreneur keeps the flat-rate regime while annual turnover does not exceed 6,000,000 dinars. Once that limit is crossed, they switch to keeping business books from the following year.
When does a flat-rate entrepreneur have to register for VAT?
VAT registration is mandatory once turnover in any 365 consecutive days exceeds 8,000,000 dinars. The VAT registration application is filed shortly after crossing the threshold, so turnover should be tracked continuously.
How much does a flat-rate entrepreneur pay?
The amount is set by a Tax Administration decision, based on a base derived from the average wage and coefficients for activity, zone and years since registration. It therefore differs from one entrepreneur to another, and we calculate it for your specific situation.
