Americans who relocate to Italy face an immediate and unavoidable challenge: navigating two different tax systems at the same time.

The United States requires its citizens to file annual tax returns and report worldwide income no matter where they live, while Italy taxes residents on global income once residency rules are met.

This combination can create double taxation risks, complex reporting requirements, and unexpected liabilities if not handled correctly.

This article provides an overview of the US and Italian tax systems as they apply to Americans moving abroad. It highlights key obligations, common pitfalls, and offers a timeline of actions to help you plan ahead and know when professional advice is essential.

The US Tax System for Americans Abroad

The United States is one of only two countries in the world that taxes its citizens on worldwide income regardless of residence. That means that even after relocating to Italy, Americans must continue filing a US tax return every year.

Annual US tax obligations include:

The US system provides mechanisms to avoid double taxation, but these require careful consideration and you should seek help before making any decisions. These tax mechanisms include:

The Italian Tax System

Italy determines tax liability based on residency. You are considered a resident for tax purposes if you spend more than 183 days in Italy in a calendar year, or if Italy becomes your primary centre of vital interests (such as family, home, or economic activity).

Once considered a tax resident, Italy will tax you on your worldwide income, including employment, self-employment, investment income, and pensions.

Some of the main features include:

Where the US and Italian Systems Overlap

The complexity for Americans in Italy lies in the overlap between the two systems.

Both countries claim worldwide taxation and although treaties and credits are designed to mitigate double taxation, there are areas where mismatches occur:

Without specific expertise, it’s easy to fall foul of both authorities, sometimes years later which can lead to financial penalties and potentially worse.

A Rough Timeline for Tax Planning

Frequently Asked Questions

Moving abroad often raises the same concerns for Americans, especially when it comes to handling two tax systems at once. Below are answers to some of the most common questions about US and Italian tax obligations.

Do Americans living in Italy still have to file US taxes?

Yes. The United States taxes its citizens on worldwide income regardless of where they live. Even if you are a tax resident in Italy, you must file a US tax return every year.

How can I avoid being taxed twice in the US and Italy?

Double taxation is avoided through a combination of the US–Italy tax treaty, the Foreign Earned Income Exclusion, and the Foreign Tax Credit. These provisions are complex and need to be applied correctly, so professional advice is strongly recommended.

When do I become an Italian tax resident?

You are considered tax resident in Italy if you spend more than 183 days in a calendar year in the country, or if Italy becomes your primary centre of vital interests (family, home, or economic ties). Once resident, you must declare worldwide income.

Do I need to report my US bank accounts to Italy?

Yes. Italian residents are required to disclose foreign assets, including overseas bank accounts, through the IVAFE tax. At the same time, US citizens must also report their Italian accounts to the IRS via FBAR and FATCA.

Can I benefit from Italy’s special tax regimes as an American?

Potentially. Italy offers options such as the €100,000 flat tax on foreign income for high-net-worth individuals and the 7% regime for pensioners moving to certain regions. Whether you qualify and whether it is beneficial alongside US obligations depends on your personal circumstances.

Do I need professional tax help or can I file myself?

Some Americans in Italy do attempt to file both returns on their own, but because of timing differences, reporting mismatches and the risk of penalties, professional help is strongly advised. Coordinated advice from both US and Italian specialists can save significant time, money, and stress.

When to Seek Professional Advice

Some expats try to manage on their own, but given the stakes, mistakes can be costly. Professional advice is strongly recommended at key points:

Cross-border taxation is highly technical. Even small oversights, like not reporting a bank account, can lead to significant penalties.
