For residents of Italy who own a US LLC

US LLC Owned From Italy: Form 5472, Taxes and Filing

You live in Italy and own a US LLC. Each year it files Form 5472 with a pro forma Form 1120, even with no US income, and the US has an income tax treaty with Italy. This page covers what to file, what to enter as your foreign tax ID, and what the treaty position means for you.

Quick answer

Do I have to file Form 5472 if I live in Italy and own a US LLC?

Usually yes. The IRS treats a single-member LLC owned from Italy as a corporation for Form 5472, so any money moving between you and the LLC, including the first deposit, triggers Form 5472 with a pro forma Form 1120. The penalty for missing it is US$25,000. The US has a tax treaty with Italy; that matters for tax on profits, not for this filing.

The yearly US filings for an LLC owned from Italy

Here is the yearly list for a single-member LLC whose only owner lives in Italy.

Every year with a related-party transaction: Form 5472, attached to a pro forma Form 1120. Forming the LLC, funding it and taking money out all count (IRS instructions). The LLC usually owes no US income tax as a disregarded entity; this is an information return.
Once, soon after you start: the BE-13 survey to the Bureau of Economic Analysis, generally within 45 days of a foreign person setting up or buying a US business (BEA rule).
Every year, to the state: whatever the formation state charges; US LLC annual fees by state lists them.
Only sometimes: Form 1040-NR, when the LLC earns income effectively connected with a US trade or business (IRS).

Missing Form 5472 costs US$25,000 per failure, and a substantially incomplete form counts as not filed.

Getting your Italian owner details ready

About you. Your passport, your address in Italy and your tax ID. For a resident of Italy, this is usually your codice fiscale, Italy's tax identification number (OECD tax ID sheet).

About the money. Every amount that moved between you and the LLC in the year, with dates. If you funded the LLC from an account in euros, the statement from that account helps us convert it to US dollars.

About the LLC. Formation papers, the EIN letter and the state where it was formed (state fees).

Is there a US tax treaty with Italy?

Yes: the IRS lists Italy among the countries with a US income tax treaty (IRS treaty list). The treaty does not remove Form 5472. What it can change is how much US tax applies to the LLC's profit and to payments you receive.

Question	With the treaty	Source
Is the LLC profit taxed in the US?	Generally only the part attributable to a US permanent establishment, such as an office or dependent agent in the US	Form 8833
Do I have to tell the IRS I rely on that?	Yes, on Form 8833 with the return; not disclosing costs US$1,000	Form 8833
Can I get lower withholding on US dividends, interest or royalties?	You can claim it on Form W-8BEN by naming Italy; otherwise 30% generally applies	W-8BEN, Pub 515

Treaty benefits depend on the exact article and on whether you qualify under it, so we check the treaty text before relying on it.

Your taxes in Italy

Italian founders use a US LLC to sell design, fashion, food and software products to US customers, often online.

How the LLC's profit is taxed in Italy is decided under the tax rules of Italy, which can treat a US LLC differently from the way the IRS does. Check that with a tax adviser in Italy. We handle the US side and can give your adviser the US figures and filings.

Common questions

I live in Italy. When is my LLC's Form 5472 due?

With the pro forma Form 1120, normally by April 15 for a calendar-year LLC. Form 7004 extends it. The US$25,000 penalty applies if it is not filed.

Which tax ID from Italy do you need from me?

Your codice fiscale, Italy's tax identification number. The IRS asks for the same foreign tax ID every year.

Does the United States have a tax treaty with Italy?

Yes. Italy is on the IRS list of US income tax treaties. The treaty can limit US tax on business profits to profits attributable to a US permanent establishment, a position disclosed on Form 8833, and lets you claim treaty rates on Form W-8BEN.

Will I pay US income tax on my LLC's profit from Italy?

Usually only Form 5472 with the pro forma Form 1120 is filed. A Form 1040-NR is needed if the LLC has income effectively connected with a US trade or business, and the treaty may limit US tax to profits attributable to a US permanent establishment.
