Frequently Asked Questions about the Flat-Rate Regime

What is the Italian regime forfettario?

The regime forfettario is a simplified flat-rate tax regime for Italian VAT holders with annual revenues up to €85,000. No VAT is charged on invoices, and taxable income is determined by applying a profitability coefficient instead of deducting actual expenses. The substitute tax rate is 5% (first 5 years for new businesses) or 15%.

How much tax do you pay under the flat-rate regime?

It depends on your sector and revenue. A professional with €40,000 revenue pays approximately 36-43% between substitute tax and INPS social contributions. The effective tax rate is lower for sectors with a low profitability coefficient (e.g., trade at 40%).

What is the difference between the 5% and 15% rate?

The 5% rate applies for the first 5 years if it is your first business activity (or you have not carried out a similar activity in the previous 3 years). After 5 years, it automatically increases to 15%.

How do INPS contributions work for flat-rate taxpayers?

Gestione Separata: 26.07% of taxable income (no minimum). Typical for professionals without a dedicated fund.
Artisans and Traders: approximately 24% with an annual minimum contribution of about €4,521 (artisans) / €4,612 (traders). Option for 35% reduction for flat-rate taxpayers.
Professional fund: variable rate depending on the specific fund (ENPAM, Inarcassa, Cassa Forense, etc.).

Is the flat-rate regime worth it?

It is advantageous if you have few deductible costs (below the complement of the coefficient), do not need to deduct VAT, and your revenue stays under €85,000. For many professionals and freelancers with low costs, the flat-rate regime is significantly more convenient than the ordinary regime.

Can you have the flat-rate regime and be employed?

Yes, since 2026 the employment income limit for accessing the flat-rate regime has been raised to €35,000 (previously €30,000). However, you cannot invoice predominantly (over 50%) to your employer or former employer (in the previous 2 years).
