Form 5472 and 1120 for Foreign-Owned LLCs: What You Need to Know

If you own a U.S. single-member LLC as a non-resident, you may need to file IRS Form 5472 and a pro-forma Form 1120 each year when reportable transactions exist. This is one of the most important compliance areas for foreign-owned LLCs.

This guide explains what these forms are, who usually files them, and how to stay compliant.

What Is Form 5472?

Form 5472 is an information return used to report transactions between a qualifying U.S. entity and certain related foreign parties.

For foreign-owned single-member LLCs, it commonly applies when the entity is treated as a disregarded entity and there are reportable transactions.

What Are Reportable Transactions?

Reportable transactions can include transfers of money, property, or services between you and your LLC, such as:

• Capital contributions
• Distributions
• Loans
• Payments for services
• Rent, royalties, or other related-party transactions where applicable

What Is the Pro-Forma 1120?

A foreign-owned single-member LLC treated as a disregarded entity does not file a normal corporate return in the same way as a corporation. However, the IRS requires a pro-forma Form 1120 as part of the Form 5472 filing path in these cases.

Who Must File?

This filing path usually applies when:

• You are not a U.S. citizen or resident
• You own a U.S. single-member LLC
• The LLC is treated as a disregarded entity
• There are reportable transactions during the year

Filing Deadline

The standard deadline is generally April 15 for calendar-year entities, and an extension may be available.

Penalties

The penalty for missing, late, or incomplete required Form 5472 filing can be $25,000 initially, and additional penalties may apply in some continued non-compliance situations.

How to File Correctly

1. Gather all transaction records between you and the LLC
2. Determine whether Form 5472 applies to your structure
3. Prepare the required forms accurately
4. Submit them using the proper IRS filing method
5. Keep supporting records and copies of everything filed

Record-Keeping Requirements

You should maintain records of all reportable transactions, including:

• Bank statements
• Invoices
• Contracts
• Transfer receipts
• Contribution and distribution records
