Why Form 5472 Is Required for Foreign-Owned LLCs

Form 5472 is one of the most misunderstood filings for non-resident founders. If your US LLC is foreign-owned and treated as a disregarded entity, the IRS expects a Form 5472 every year, even if you had zero revenue.

Form 5472 compliance overview

The short version

Form 5472 reports transactions between your LLC and any related foreign party. It is informational, but the IRS enforces it with serious penalties when it is missing or late.

If you are a non-resident owner of a single-member LLC, you should assume Form 5472 is required unless a qualified advisor says otherwise.

Who must file Form 5472

You must file if all of the following are true:

  • Your LLC is treated as a disregarded entity.
  • At least 25% of the LLC is owned by a foreign person.
  • The LLC had any reportable transactions with related parties.

What counts as a reportable transaction

Reportable transactions include:

  • Capital contributions from the foreign owner.
  • Reimbursements or payments to the owner.
  • Loans, interest, or fees between the LLC and its owner.
  • Purchases of services or assets from a related party.

The penalty that surprises people

Missing Form 5472 is not a small administrative error. The default penalty is $25,000 per missed or late form. Additional penalties can apply after IRS notices.

How to stay compliant

Follow this workflow each year:

  1. Track all owner-related payments in a simple ledger.
  2. Compile totals for each reportable category.
  3. Prepare a pro forma Form 1120 to attach to Form 5472.
  4. File by the deadline or request an extension with Form 7004.
