The United States taxes you because you are a citizen. Italy taxes you because you live there. Nobody coordinates the two for you — and the treaty only works if someone actually applies it, in the right order, on both returns.
Two tax systems, one income. Italian residence analysis, the 7% pensioner regime and new-resident flat tax, treaty relief, Quadro RW on your US assets, and Italian filings planned and coordinated with your US professionals.

The 45-minute consultation (USD 250) produces the residence answer and the treaty map for your income. Ongoing Italian advisory, regime elections, monitoring compliance and voluntary correction of past years are quoted case-by-case. Italian filings are prepared and coordinated as part of the engagement; US returns remain with your US-licensed professionals, with whom we work directly.
If you live in Italy and you are a US citizen or green-card holder, you file in both countries every year. The United States taxes you because of your status; Italy taxes you because you are resident there. Double taxation is then relieved through the Italy–US treaty and foreign tax credits — but only to the extent someone computes it correctly, on the right return, in the right year.
That is the whole job: two systems, one income, deliberate coordination.
Italian residence for tax purposes rests on art. 2 TUIR, as amended by D.Lgs. 209/2023: registration in the resident population register (anagrafe), habitual abode, or domicile in Italy for most of the tax year. Meet a criterion and Italy taxes worldwide income for the whole year.
Two consequences people underestimate:
The Italy–US income tax convention allocates taxing rights by category and provides credit relief; the saving clause preserves each state's right to tax its own residents and citizens, which is why a US citizen in Italy does not simply stop filing in the US.
Where it matters most:
Article 165 TUIR governs the Italian credit for foreign taxes, with limits and documentation requirements. Credits that are not claimed, or claimed against the wrong income, are simply lost.
7% flat tax for foreign pensioners — art. 24-ter TUIR. Foreign-source pension income taxed at a 7% substitute rate for a defined number of years, for individuals transferring residence to qualifying municipalities in southern regions below a population threshold, with prior-non-residence conditions. For a retiree with a substantial US pension this can be the difference between a comfortable move and an unaffordable one.
New residents — art. 24-bis TUIR. An annual flat substitute tax on foreign-source income for individuals transferring residence to Italy, in the amount set by law at the time of election. Designed for significant foreign income and wealth; interacts with monitoring obligations and with the treaty.
Inbound workers — D.Lgs. 209/2023. Partial exemption of Italian employment or self-employment income for qualifying workers who transfer residence, with qualification, prior-residence and stay commitments.
All three depend on the year residence begins and on a correct election. Advisory that starts after the first Italian return is often advisory that starts one year too late.
As an Italian resident you report your non-Italian assets — which for an American means almost everything — in Quadro RW:
Meanwhile FBAR and FATCA obligations continue on the US side. Two monitoring systems, both live, neither aware of the other.
This is where relocation plans succeed or fail financially.
The recommendation is always the same: model the portfolio against the Italian rules before the residence date, when restructuring is still an option.
If you are self-employed or freelance and you perform the work in Italy, Italian taxation follows the activity, and with it Italian VAT registration and a social-security position. The Italy–US social security agreement determines which system you contribute to and a coverage certificate is the document that proves it. Remote employees of US companies raise the additional question of the employer's Italian obligations — a question US employers frequently have never considered.
Unfiled Italian returns and omitted Quadro RW are correctable. Voluntary correction reduces penalties substantially compared with assessment, and the sequence matters: establish the residence years, reconstruct income and assets, then file in order. Filing one year in isolation while leaving an earlier year exposed is a common and expensive mistake.
We prepare, plan and coordinate the Italian side: residence analysis, treaty mapping, regime elections, Quadro RW, IVIE and IVAFE, the Italian return calendar, and voluntary correction where needed. Our qualification is Italian — Avvocato, Dottore Commercialista and Revisore Legale.
We do not prepare US returns and we do not give US-law advice. We work directly with your US-licensed professionals and give them the Italian positions and figures they need, so the two returns are consistent. Divergence between the two sides is the most common cause of trouble, and it is entirely avoidable.
Send the free written request with your residence date, income types and the accounts you hold, or book the 45-minute consultation (USD 250). If you are still planning the move, the highest-value conversation happens before you register in a comune — that is when the regimes, the timing and the portfolio are still yours to arrange.
Yes, if you are an Italian tax resident. Italy taxes residents on worldwide income, and residence follows anagrafe registration, habitual abode or domicile for most of the tax year. Your US filing does not substitute for an Italian one, and the two returns have to be reconciled deliberately.
It allocates taxing rights by type of income and provides credit relief, with a saving clause that preserves each state's right to tax its own residents and citizens. In practice it means computing which country taxes first, claiming the credit on the correct return in the correct year, and documenting it. The relief is real but it is not automatic — an unclaimed or misordered credit is simply lost money.
For the right person, yes: foreign-source pension income taxed at a 7% substitute rate for a defined number of years. But eligibility is strict — transfer of residence to a qualifying municipality in the southern regions below a population threshold, with prior non-residence conditions — and it must be elected properly for the year residence begins. It is not something to discover in year three.
The US tax-free character of a Roth is a feature of US law and is not automatically mirrored in Italian characterization. Italian treatment of distributions and internal growth has to be analysed against Italian rules and the treaty rather than assumed. This is one of the highest-value questions to settle before moving.
Yes. As an Italian resident, foreign assets go in Quadro RW, with IVAFE on financial assets and IVIE on foreign real estate. The obligation covers US accounts, brokerage holdings, crypto and property, and omission carries monitoring penalties independent of any tax due.
Voluntary correction is available and is dramatically cheaper than being found. The order matters: establish which years you were resident, reconstruct income and asset positions, then file with reduced penalties. Doing it in the wrong order — for instance filing one year while leaving an earlier one open — can create more exposure than it resolves.
No. Our qualification is Italian: Avvocato, Dottore Commercialista and Revisore Legale. We prepare and coordinate the Italian side and give your US-licensed professionals the Italian figures, positions and treaty analysis they need. We do not present ourselves as US tax preparers and we do not advise on US law.
Employment income is generally taxable where the work is physically performed, which means Italy, with treaty and credit mechanics on the US side and a real question about your employer's Italian obligations. Add social security: the Italy–US agreement determines which system you contribute to, and getting a coverage certificate matters. This is the fact pattern where people most often owe more than they expected.
