Understanding citizenship-based taxation, foreign tax credits, FEIE thresholds, and how to avoid double taxation while living in Italy.

Mastering US expats Italy taxes is one of the most critical legal steps for Americans moving to or living in Italy. Because the United States enforces citizenship-based taxation, American expats must file annual US tax returns on their worldwide income regardless of where they live or earn their livelihood.

Fortunately, mechanisms like the Foreign Earned Income Exclusion (FEIE), Foreign Tax Credits (FTC), and the US-Italy Tax Treaty exist to eliminate double taxation when properly filed. For guidance on local Italian bureaucracy and relocation compliance, visit our .

To properly handle US expats Italy taxes, you must first determine your Italian tax status. If you qualify as an Italian tax resident, you are subject to Italian taxation on your domestic and worldwide income.

Criteria for Italian Tax Residency: Under Italian tax law, you are considered a tax resident if you satisfy at least one of the following criteria for more than 183 days in a calendar year:

1⃣ Registered in the official civil registry (*Anagrafe della Popolazione Residente*) of an Italian municipality.

2⃣ Established your primary domicile or center of economic and personal interests in Italy.

3⃣ Maintained habitual residence on Italian territory.

Even if you become a full Italian tax resident, you must still submit your annual return to the IRS. The US-Italy Income Tax Treaty contains tie-breaker rules and a “Savings Clause” that defines which country holds primary taxing rights over specific income types.

When filing US expats Italy taxes, the IRS provides two major provisions to prevent double taxation on earned income:

Provision Name IRS Form Key 2025/2026 Threshold & Rule Foreign Earned Income Exclusion (FEIE) Form 2555 Excludes up to $130,000 of foreign earned income per qualifying individual. Foreign Tax Credit (FTC) Form 1116 Dollar-for-dollar credit for taxes paid to Italy against US tax liabilities.

To claim the exclusion using Form 2555, you must meet either the **Physical Presence Test** (spending at least 330 full days outside the US during a consecutive 12-month period) or the **Bona Fide Residence Test** (establishing continuous, uninterrupted residency in Italy for an entire tax year).

Because Italian income tax rates (*IRPEF*) are generally higher than US federal rates, many expats benefit more from claiming the Foreign Tax Credit on Form 1116. This provides a dollar-for-dollar credit for Italian taxes paid, reducing US tax liability to zero and generating excess credits that can be carried forward for up to 10 years.

Managing filing timelines and understanding social security contributions is essential for avoiding IRS interest charges or penalties:

Automatic 2-Month Extension (June 15): US citizens residing abroad on April 15 receive an automatic filing extension to June 15. However, any taxes owed must still be paid by April 15 to avoid interest accumulation.

Extension to October 15: You can file Form 4868 to extend your tax filing deadline to October 15. Note that extensions to file do not grant an extension of time to pay taxes due.

US-Italy Social Security Totalization Agreement: This agreement prevents workers from paying social security taxes to both countries on the same earnings. If a US company sends you to work in Italy for 5 years or less, you generally remain covered under US Social Security. Self-employed individuals or those employed by Italian companies contribute directly to Italy’s *INPS* system.

Living in Italy usually requires opening a local bank account. US expats must report foreign financial assets when specific statutory balances are crossed:

FBAR (FinCEN Form 114): Mandatory if the aggregate value of all foreign financial accounts exceeds **$10,000** at any point during the calendar year. This is filed separately through the BSA E-Filing System.

FATCA (Form 8938): Filed with your Form 1040 if foreign specified financial assets exceed threshold limits ($200,000 on the last day of the tax year or $300,000 at any time during the year for single filers living abroad).
