1. Partita IVA and forfettario regime: solo launch
Partita IVA in forfettario regime has become since 2019 the most-used status for launching an independent activity in Italy.
Partita IVA (VAT number) is assigned by Agenzia delle Entrate to any person exercising an independent economic activity in Italy. It is the equivalent of the French SIRET number combined with the VAT identifier. To start, two main fiscal regimes are possible: ordinario (taxation at progressive IRPEF on real profit) or forfettario (flat taxation at 15% or 5% on a turnover coefficient).
The forfettario regime, instituted in its current form in 2015 and extended in 2019, applies a unique 15% tax rate on a flat coefficient base varying by activity (40% for craftspeople, 67% for traders, 78% for liberal professions, 86% for intellectual professions). For a new founder, this rate is reduced to 5% for the first 5 years under conditions (not having exercised similar activity in the previous 3 years, not having held more than 50% of an active company). The turnover ceiling is €85,000 per year since 2023.
Forfettario presents several structuring advantages: no VAT to invoice or recover (franchise regime), no IRAP, no IVA, simplified accounting (keeping a single revenue register), no IRPEF withholding tax, exclusion of cross-border operations declaration (esterometro). INPS contributions gestione separata (26.07% of taxable income in 2025) or INPS artigiani/commercianti (annual flat €4,200 to €4,800 minimum + additional contributions beyond €17,504 of income) remain due.
The forfettario pitfall for very high incomes
Beyond a certain turnover level (generally €50,000 to €60,000 by activity), forfettario can become less advantageous than ordinario regime despite the apparent 15% rate. The flat coefficient (40 to 86%) creates a tax base that does not account for real professional expenses. For high-expense activities (real estate, equipment, travel), a cross-calculation is necessary — the BoostPro IA simulator produces this arbitrage.
