The two-jurisdiction reality A US citizen who moves to Italy — or who invests in Italian assets while staying in the US — never escapes the US tax system. The US is one of two countries in the world (with Eritrea) that taxes citizens worldwide regardless of residency. Italy adds its own residency-based system on top. The result is two parallel tax returns every year as long as US citizenship is held. The job of cross-border planning is to ensure income is not taxed twice — through the Italy–US Tax Treaty (1984) and the Foreign Tax Credit. When you become Italian tax resident Under article 2 TUIR, you are Italian tax resident in a given calendar year if, for the greater part of the year (183 days), any one of the following is true: - You are registered with the Anagrafe (municipal civil registry), or - You have your domicilio (centre of interests — family, business, social ties) in Italy, or - You have your residenza (habitual abode) in Italy. Note the or — a single factor triggers residency. Moving with the family and signing a lease for a year typically establishes both residenza and domicilio. Italy taxes residents on worldwide income. Non-residents are taxed only on Italian-source income. Italian income tax rates (IRPEF) — 2026 brackets The 2026 IRPEF (national income tax) brackets: - Up to €28,000 — 23% - €28,001 to €50,000 — 35% - Over €50,000 — 43% Regional (1.23%–3.33%) and municipal (0%–0.9%) surcharges apply on top. Effective marginal rates therefore exceed 45% at the top bracket. Capital gains and investment income - Capital gains and dividends on listed securities: flat 26% substitute tax. - Government bonds (Italian and EU-equivalent): preferential 12.5%. - Interest on bank deposits: 26% substitute tax, generally withheld by the Italian payer. - US-source dividends paid to an Italian resident: Italian 26% applies; US withholds 15% under the Treaty; the Italian tax is computed net of the foreign withholding via credit. US tax filing — what doesn't go away You still file Form 1040 every year. Key tools: - FEIE (Form 2555): exclude foreign earned income up to ~$130,000 (2025 figure, indexed) — only for earned income, not investment income. - FTC (Form 1116): credit Italian income tax paid against US tax on the same income — usually more powerful than FEIE for high earners and investors. - FBAR (FinCEN 114): required if aggregate foreign-account balance exceeds $10,000 at any point — Italian bank accounts count. - Form 8938 (FATCA): required at higher asset thresholds for foreign financial assets. US-based retirement accounts (401(k), IRA, Roth) are not Italian-favored. Italian tax treatment of US retirement distributions is governed by Treaty article 18 and depends on the type of account — Italian advisors often misclassify Roth IRAs. The Italy–US Tax Treaty (1984) — what it actually does The Treaty: - Allocates primary taxing rights between the two states by income category (employment, business, dividends, interest, royalties, real estate, pensions, etc.) - Caps source-state withholding (e.g. dividends to 15%) - Provides the residency tie-breaker for dual residents (article 4) - Mandates Foreign Tax Credit relief on both sides It does not: - Eliminate the US obligation to file Form 1040 - Eliminate FBAR or FATCA reporting - Override Italian wealth taxes (IVIE/IVAFE) — those are levied independently Special regimes worth knowing - Impatriate regime (lavoratori impatriati): Italian-sourced employment/self-employment income taxed on only 50% of the base for 5 years, if you meet the conditions (broadly: not Italian tax resident in the preceding 3 years, commitment to stay 4+ years). - Flat tax for new residents (€200k regime): annual flat tax of €200,000 on all foreign-source income for high-net-worth individuals moving Italian residency. Powerful for US citizens with substantial US investment income, but does not relieve the US filing obligation. - Pensioner 7% regime: flat 7% on foreign pension income for retirees moving to qualifying southern Italian municipalities.

Yes. The US taxes citizens on worldwide income regardless of residency. You file Form 1040 every year, using FEIE or Foreign Tax Credit to avoid double taxation, plus FBAR and possibly Form 8938.
When for more than 183 days in a calendar year you are either registered with the Anagrafe, OR have your domicilio (centre of interests) in Italy, OR have your habitual abode in Italy. Any single factor triggers residency.
Three IRPEF brackets: 23% up to €28,000; 35% from €28,001 to €50,000; 43% above €50,000. Regional and municipal surcharges apply on top, pushing the effective top marginal rate above 45%.
A €200,000 annual flat tax on all foreign-source income for high-net-worth individuals moving Italian residency, valid up to 15 years. It does not eliminate the US Form 1040 obligation for US citizens.
No — Italian tax treatment depends on Treaty article 18 and account type, and Roth IRA tax-free status is not automatically recognised. Distributions and growth should be reviewed case-by-case before establishing Italian residency.
