Form 5472 Filing Requirement Checker
Form 5472 is required for foreign-owned US entities with reportable transactions. The penalty for failure to file is $25,000 minimum — and most foreign-owned single-member LLCs need to file even with $0 of income. Answer 5 questions to find out if you need to file.
What counts as a "reportable transaction"?
- Sales of stock in trade or other property
- Rents and royalties received or paid
- Interest received or paid (including loans to/from owners)
- Commissions and other compensation
- Premiums received or paid for insurance/reinsurance
- Amounts loaned or borrowed (and outstanding balances at year-end)
- Contributions to capital by the foreign owner
- Distributions / dividends to the foreign owner
- For SMLLCs: any money flowing between the LLC and its foreign owner is reportable, including initial capitalization wires.
Even a $1 transfer triggers the filing requirement for a foreign-owned SMLLC.
Frequently asked questions
Do single-member foreign-owned LLCs really need to file Form 5472?
Yes. Since 2017 (Treas. Reg. §301.7701-2(c)(2)(vi)), single-member foreign-owned LLCs are treated as corporations solely for §6038A reporting. You must file Form 5472 + a pro-forma Form 1120 every year — even with $0 income or $0 reportable transactions.
What counts as a reportable transaction?
Any monetary or non-monetary exchange between the LLC and its foreign owner, foreign related parties, or anyone the owner controls. Examples: capital contributions, distributions, loans, fees, royalties. Even an owner paying a startup fee from a personal account creates a reportable transaction.
What is the penalty for not filing?
$25,000 per form, per year. If the IRS notices and you do not file within 90 days of notice, an additional $25,000 every 30 days. Penalties can stack across multiple years — non-filers have faced $100,000+ exposure on otherwise inactive LLCs.
What is the deadline?
Form 5472 + Form 1120 are due April 15 (calendar-year LLCs) or the 15th day of the 4th month after fiscal year-end. You can extend to October 15 with Form 7004. Most foreign owners use the extension because the form requires US-formatted financial statements.
Can I file Form 5472 electronically?
No. As of 2026 the IRS does not accept Form 5472 e-filing for foreign-owned disregarded entities. You must paper-file to the Ogden, Utah service center (mailing address listed in the Form 5472 instructions). Use certified mail with return receipt for proof.
