Moving to Italy — a guide for American founders
US citizens and residents opening a freelance business or partita IVA in Italy.
Market access & permits
As a non-EU citizen, American founders generally need a residence permit that allows self-employment (lavoro autonomo) before registering a partita IVA — typically via the decreto-flussi quota, or by converting an existing permit (study, family, EU long-term residence). Once legally resident, the forfettario regime is open to you on the same terms as everyone else. If you're staying in the US and only invoicing Italian clients, you may not need an Italian registration at all — that turns on tax residency, not nationality.1
Tax residency — where you actually owe tax
Italy taxes residents on worldwide income. You become tax-resident if, for most of the year (183+ days), your registered residence, habitual abode or centre of vital interests is in Italy. Many American founders trip on this when they relocate mid-year or keep a home abroad — the day count, not your passport, decides where you owe tax.3
The forfettario regime & impatriati
Once you're an Italian tax resident, the forfettario regime is open to you on the same terms as everyone else — a coefficient on revenue (set by your ATECO code) and a 5%/15% substitute tax, up to €85,000.2 To register the partita IVA you'll file with the Agenzia delle Entrate.5
If you move your tax residence to Italy and meet the conditions (broadly: not resident in the prior years, and a commitment to stay), the impatriati regime can exempt 50% of qualifying income from IRPEF. For higher earners it can beat the forfettario — worth modelling both. Many relocating American professionals qualify.4
Traps for American founders
- •US citizens are taxed by the IRS on worldwide income regardless of residence — you'll likely file in both countries and lean on the US–Italy tax treaty + foreign tax credits to avoid double taxation.
- •FATCA/FBAR reporting of Italian bank and business accounts continues even after you move.
- •The forfettario's flat substitute tax interacts awkwardly with US foreign-tax-credit rules — coordinate with a cross-border advisor.
Frequently asked questions
Can a US citizen open a partita IVA in Italy?
Yes, once you hold a residence permit allowing self-employment (or are an EU long-term resident / family-permit holder). The forfettario regime is then available on standard terms. US citizens should plan for continued IRS filing under the US–Italy treaty.
Do American founders qualify for the forfettario regime in Italy?
Yes. The forfettario regime is open to Italian tax residents regardless of nationality, subject to the €85,000 revenue ceiling and the standard eligibility rules. Your activity's ATECO code sets the profitability coefficient (40–86%).
Is the impatriati regime available to American founders who move to Italy?
Often, yes. If you transfer your tax residence to Italy and meet the conditions, the impatriati regime can exempt 50% of qualifying income from IRPEF — sometimes a better deal than the forfettario for higher earners.
