Complete Guide to Form 5472 for Foreign-Owned U.S. Businesses
Everything you need to know about IRS Form 5472, including who must file, critical deadlines, the $25,000 penalty, reportable transactions, and step-by-step compliance instructions for foreign-owned US entities.
1. What Is Form 5472?
Form 5472, officially titled “Information Return of a 25% Foreign-Owned US Corporation or Foreign Corporation Engaged in a US Trade or Business,” is an information return required by the IRS. It is not a tax return that computes tax liability but rather a disclosure form that reports transactions between a US entity and its foreign related parties.
Form 5472 is filed with a pro forma tax return. For single-member LLCs that are disregarded entities, the form is attached to a pro forma Form 1120. This pro forma return serves only as a vehicle for filing Form 5472 and does not report tax liability.
The form helps the IRS track cross-border transactions between related parties to ensure proper reporting and prevent tax avoidance through transfer pricing manipulation.
Key Takeaway: Form 5472 is an information return, not a tax return. However, the penalty for failing to file is $25,000 per form, per year, with no reasonable cause exception.
2. Who Must File Form 5472?
The following entities must file Form 5472:
- A US corporation that is 25% or more owned by a single foreign person
- A foreign corporation engaged in a US trade or business
- A US single-member LLC that is a disregarded entity owned by a foreign person
- A US partnership with 25% or greater foreign ownership (in certain circumstances)
Note: A single-member LLC owned by a foreign person is treated as a disregarded entity and MUST file Form 5472, even if the LLC has no activity or income.

5. Penalties for Non-Compliance
The penalty for failing to file a complete and correct Form 5472 is $25,000 per form, per tax year. There is no reasonable cause exception, making this one of the most severe information return penalties in the Internal Revenue Code.
If the failure continues for more than 90 days after the IRS sends a notice, an additional $25,000 penalty is assessed. This means a single unfiled Form 5472 can result in $50,000 in penalties.
The $25,000 penalty applies per form, per year. A foreign-owned LLC that has never filed Form 5472 for the past 3 years faces $75,000 in penalties.
