Practical guide for Italians relocating to Miami: AIRE registration is not enough, the role of art. 2 TUIR, the Italy-USA Treaty tie-breaker, and the most common audit triggers in the first three years.

Many Italians who move to Miami believe that registering with AIRE (the registry of Italians abroad) is sufficient to terminate Italian tax residence. It is not. AIRE is a necessary but not sufficient condition. The Italian Tax Authority routinely challenges residence transfers where the substantive ties to Italy were not properly severed.
Article 2 of the Italian Income Tax Code defines a tax resident as anyone who, for the majority of the tax year (more than 183 days), meets at least one of:
To leave Italian tax residence, you must defeat all three tests for the majority of the year. AIRE registration only addresses the first.
The Agenzia delle Entrate's cross-border audit unit looks at:
When you become a US tax resident under the Substantial Presence Test and Italy still claims you under art. 2 TUIR, dual residence is resolved by Article 4 of the 1984 Italy-USA Treaty in this hierarchy:
A treaty tie-breaker in your favor protects you from Italian worldwide taxation, but it must be claimed (often via Form 8833 on the US side and proper disclosure on the Italian side) and documented.
Before boarding the flight to MIA:
The Italian Tax Authority can audit residence transfers up to five years back. The first three years after departure are the highest-risk window. Maintain:
Florida has no state income tax, no state estate tax, and no state inheritance tax. The combined US federal-state tax burden in Florida is therefore among the lowest in the country for high earners. This makes Miami particularly attractive for Italians with portable income (consulting, royalties, capital gains).
But the federal exposure is full: US worldwide income, FBAR, Form 8938, FATCA. The state savings do not eliminate the federal compliance load.
Result: Italian residence terminated mid-2026 (under the majority of year test, technically 2027 is the first full year of non-residence). Treaty tie-breaker available in 2026 to protect against split-year issues. From 2027 onward, US worldwide taxation applies, with foreign tax credit on residual Italian-source income (Italian rental property, if any).

No. AIRE only resolves the registry test. You must also defeat the domicile and habitual-residence tests of art. 2 TUIR for the majority of the tax year.
Family in Italy is the strongest single indicator of retained domicile. The Italian Tax Authority will likely challenge the transfer. Treaty tie-breaker may help if the US ties are genuinely stronger.
Under the strict reading of art. 2 TUIR, residence is determined for the majority of the calendar year. A move after July typically means full Italian residence for that year unless the Treaty tie-breaker applies.
No state income tax, no state estate tax, no state inheritance tax. The federal exposure is full, but the combined burden is among the lowest in the US.
Yes, but you must analyze CFC exposure under both Italian art. 167 TUIR and US Subpart F/GILTI. Restructuring before the move is often the right answer.
