Do Americans on Italy's nomad visa still file US taxes?

Updated 2026-11-12 · Taxes & family guide · Not legal advice

Yes. US citizens and green card holders file US returns on worldwide income wherever they live. If you also become an Italian tax resident, the US–Italy income tax treaty, the foreign tax credit and, in some cases, the foreign earned income exclusion are the tools that prevent paying full tax twice, and you must report foreign accounts on the FBAR if they exceed $10,000 in total at any point in the year.

US obligations from Italy
Item	What it is	Where
Form 1040	Annual return on worldwide income	IRS
Foreign tax credit (Form 1116)	Credit for Italian income tax paid	IRS
Foreign earned income exclusion (Form 2555)	Excludes some foreign earned income if you qualify; amount changes yearly	IRS
FBAR (FinCEN 114)	Report foreign accounts above $10,000 aggregate	FinCEN
Form 8938	Foreign financial assets above thresholds	IRS
US–Italy treaty	Residence tie-breakers, pensions, credits	IRS treaty page

Credit or exclusion?

Italian tax rates are often higher than US rates at the same income, so many Americans in Italy rely on the foreign tax credit rather than the exclusion. This depends on your income and Italian regime; ask a US expat tax preparer.
