Guide to Form 5472 Filing Requirements for Single-Member LLCs

⚡ Bottom Line Summary

The Bottom Line	Foreign-owned single-member LLCs (SMLLCs), while treated as "disregarded entities" for income tax purposes, are classified as domestic corporations for information reporting. A foreign-owned U.S. single-member LLC treated as a disregarded entity files Form 5472 with a pro forma Form 1120 for a tax year when applicable reporting requirements are met, including reportable transactions with its foreign owner or related parties; U.S. taxable income is not determinative.
Key Insight	Some non-monetary transactions may be reportable under applicable rules; whether Form 5472 is required depends on the entity's classification, parties, transaction type, and facts. A covered failure to file a complete and correct Form 5472 may result in a $25,000 penalty; assessment and any available relief depend on applicable law and the facts.
Action Required	Review the entity's reportable transactions and current IRS instructions. If applicable requirements are met, verify that the entity has an EIN and determine the filing deadline based on its classification and tax year.
