Quick Answer
What is Form 5472 and who must file it?
Form 5472 is an IRS information return that every U.S. corporation or U.S.-disregarded entity with at least 25% foreign ownership must file annually to disclose reportable transactions with foreign related parties. For a foreign-owned single-member LLC, Form 5472 must be attached to a “pro forma” Form 1120 and mailed or faxed to the IRS. Failure to file triggers an automatic $25,000 penalty per form under IRC §6038A.
Key Takeaways
- Foreign-owned single-member LLCs must file Form 5472 + Pro Forma 1120 even with zero income or activity.
- The filing deadline is April 15 (or 15th day of the 4th month after fiscal year-end). Form 7004 grants a 6-month extension.
- The penalty for non-filing is $25,000 per form per year, auto-assessed by the IRS, plus continuing penalties.
- Most first-time foreign filers qualify for full penalty abatement under reasonable cause if filed promptly.
- Multi-member LLCs are partnerships — they file Form 1065 + 8804/8805 + Schedules K-2/K-3 instead.
- Owner-level returns (Form 1040-NR or 1120-F) are required if the LLC has ETBUS or ECI.
