What to include so the first reply is useful

- The countries involved and the type of asset, company or income.

Who we can help — and who we refer elsewhere
Every engagement starts with a 45-minute online consultation (USD 250) or a free written contact request. We reply in Italian or English, usually within one business day.
- We help: Italians in the U.S., Italian companies operating in the United States, and U.S. persons with Italian assets, income, companies or inheritances.
- We work alongside your existing Italian accountant or U.S. professional when one is already in place, on the cross-border part only.
- We do not give opinions on U.S. federal or Florida law on our own: those are handled with appropriately licensed U.S. professionals.
- For immigration filings we provide orientation and refer the case to licensed U.S. immigration counsel.

Clients outside Italy and the United States
A large part of the practice concerns people and companies that are neither resident in Italy nor in the United States: Italians living in Switzerland, the UAE, the UK, Germany, Brazil or Latin America who still own Italian assets; non-Italian founders setting up a Florida LLC from a third country; families with heirs spread across several jurisdictions.
Working language is English or Italian, meetings are held online across time zones, and documents are signed remotely through powers of attorney where the applicable law allows it. Italian law and Italian tax matters are advised on directly; U.S. federal and Florida law matters are handled in coordination with appropriately licensed U.S. professionals; the law of your country of residence is addressed with a local professional there.
- Non-resident owners of Italian real estate, bank accounts, company shares or inheritances.
- Founders in third countries opening a U.S. company, bank account and reporting position.
- Cross-border successions where heirs, assets and residence are in three or more countries.
- Italians abroad dealing with AIRE, Italian tax residence, Quadro RW and treaty positions.
- Free written request in English or Italian from any country; paid 45-minute online consultation (USD 250) when you want a decision in one call.
