Form 5472 Explained: A Guide for Foreign Owners of U.S. LLCs

If you live outside the United States and own a U.S. LLC, there is a good chance you have an annual filing obligation you have never heard of: Form 5472. Many international founders only discover it when an IRS penalty notice arrives. This guide explains what the form is, who must file it, and how to stay compliant.

What is Form 5472?

Form 5472 is an information return. Its purpose is not to calculate tax but to tell the IRS about transactions between a U.S. company and its foreign owner or other related parties. The IRS uses it to see money and property moving between a U.S. business and foreign persons connected to it.

Who has to file?

Two main groups file Form 5472:

• U.S. corporations that are at least 25% foreign-owned and have reportable transactions with a foreign related party. They attach Form 5472 to their regular Form 1120.
• Foreign-owned U.S. single-member LLCs (known as disregarded entities). Since tax years beginning in 2017, these LLCs are treated as corporations for this reporting purpose, so they must file Form 5472 even though they normally pay no U.S. corporate tax.

The second group is where most international founders fall. If you formed a U.S. LLC from Nigeria, the UK, India, the UAE, or anywhere else, and you are its only owner, this rule very likely applies to you.

What counts as a reportable transaction?

For a foreign-owned single-member LLC, almost any movement of money or value between you and the company counts, including:

• Money you put into the company, such as funding its bank account (capital contributions).
• Money you take out of the company (distributions).
• Loans between you and the company, in either direction.
• Company expenses you pay personally, including the fees to form the LLC.
• Payments for services, rent, or goods between you and the company.

What is the pro forma Form 1120?

A foreign-owned single-member LLC does not file a normal corporate tax return. Instead, it files Form 5472 attached to a pro forma Form 1120. "Pro forma" means only a few parts are completed, mainly the company's name, address, and EIN. The pro forma return exists so the IRS has a return to attach Form 5472 to; it does not mean the LLC owes U.S. corporate income tax.

When is Form 5472 due?

For companies that use the calendar year, Form 5472 and the pro forma Form 1120 are due on April 15 of the following year. For example, the return for the 2026 tax year is due April 15, 2027.

If you need more time, you can file Form 7004 by April 15 to extend the deadline by six months, to October 15. The extension must be filed on time to be valid.

What are the penalties?

The penalties are serious:

• $25,000 for each Form 5472 not filed on time, or filed incomplete, per tax year.
• An additional $25,000 for each 30-day period the failure continues after 90 days from an IRS notice.

In addition, when required information is not filed, the IRS's time limit for assessing tax on that return generally does not start. In other words, the year stays open.

What documents will you need?

Preparing Form 5472 usually requires:

• Your LLC's formation documents (Articles of Organization) and formation date.
• Your EIN confirmation letter from the IRS.
• The owner's full name, address, country of residence, and foreign tax ID number if one exists.
• Bank statements for the year, showing money put in and taken out.
• Records of any company expenses paid personally, including formation costs.

The company is also expected to keep records that support the amounts reported.

Already missed a year?

You are not alone, and it is usually better to act than to wait. Missed years can be filed late. Where you had a genuine reason for not filing, such as not knowing about the requirement despite acting in good faith, a reasonable cause statement can be included to ask the IRS for penalty relief. Relief is not guaranteed, but filing before the IRS contacts you generally puts you in a stronger position.
