Form 5472: The $25,000 Penalty Every Foreign-Owned LLC Must Know About
Form 5472: The $25,000 Penalty Every Foreign-Owned LLC Must Know About Form 5472: The $25,000 Penalty Every Foreign-Owned LLC Must Know About Key Takeaways Why a single-member LLC triggers Form 5472 The pro forma Form 1120: what it is and what it is not The penalty regime: $25,000 with no ceiling What the form actually asks for Common situations we see Catching up: reasonable cause and penalty abatement Next step In short: The form is Form 5472, Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business. The penalty for not filing it is $25,000 per form, per year, with no cap and no statute of limitations. If you are a non-US person who owns a single-member LLC in the United States, you have a federal filing obligation that most domestic preparers never mention. It applies every year the LLC exists regardless of whether the entity earned a single dollar. The form is Form 5472, Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business. The penalty for not filing it is $25,000 per form, per year, with no cap and no statute of limitations. This is not an edge case. It is the most common compliance gap we see among foreign-owned US entities, and it is almost always the result of the owner never having been told the obligation existed. The penalty for not filing it is $25,000 per form, per year, with no cap and no statute of limitations. A domestic single-member LLC owned by a foreign person is treated as a corporation for the purposes of IRC § 6038A. Even a single capital contribution of $100 to open a bank account is a reportable transaction. If the IRS issues a notice of failure and the form is still not filed within 90 days, an additional $25,000 applies for each 30-day period the failure continues. There is no statute of limitations on an unfiled information return. First-time penalty abatement (FTA) under IRM 20.1.1.3.6.1 is another avenue if the taxpayer has a clean compliance history for the three preceding years. A domestic single-member LLC owned by a foreign person is treated as a corporation for the purposes of IRC § 6038A. A domestic single-member LLC owned by a foreign person is treated as a corporation for the purposes of IRC § 6038A. This classification was introduced by final regulations under TD 9796, effective 1 January 2017. Before that date, a disregarded entity owned by a foreign person had no standalone federal filing requirement. After it, the entity must file a pro forma Form 1120 (US Corporation Income Tax Return) with Form 5472 attached, reporting all reportable transactions between the LLC and its foreign owner or other related parties. A reportable transaction is broadly defined. It includes capital contributions, loans, payments for services, rent, the use of property, and any amounts paid or received between the LLC and its foreign related parties. Even a single capital contribution of $100 to open a bank account is a reportable transaction. The pro forma Form 1120 filed alongside Form 5472 is not a tax return in the usual sense. The pro forma Form 1120 filed alongside Form 5472 is not a tax return in the usual sense. The LLC is still a disregarded entity for income tax purposes it does not owe federal income tax. The pro forma return exists solely as a vehicle for delivering Form 5472 to the IRS. It is filed with zeros on the income lines and the LLC’s EIN (Employer Identification Number) in the header. You need an EIN before you can file. If the LLC was formed without one, applying for an EIN is the first step and for foreign owners without a Social Security Number, the application process itself has specific requirements (Form SS-4 filed by phone, fax, or mail rather than online). Under IRC § 6038A(d), the penalty for failing to file Form 5472 or filing one that is substantially incomplete is $25,000 per form, per year. Under IRC § 6038A(d), the penalty for failing to file Form 5472 or filing one that is substantially incomplete is $25,000 per form, per year. If the IRS issues a notice of failure and the form is still not filed within 90 days, an additional $25,000 applies for each 30-day period the failure continues. There is no statutory maximum. Critically, there is no statute of limitations on an unfiled information return. Unlike a filed return, where the IRS generally has three years to assess additional tax, an unfiled Form 5472 leaves the door open indefinitely. An LLC formed in 2018 that has never filed could face penalties stretching back to its first year of existence. The IRS has been actively pursuing these penalties. Automated notices (CP 15 and CP 215) are generated when a Form 5472 obligation is identified but no filing appears in the system. The penalty is assessed automatically it does not require an audit or an examiner’s judgment. Form 5472 requires the reporting entity to identify itself, identify its 25% foreign owner (or owners), and list all reportable transactions during the tax year. Form 5472 requires the reporting entity to identify itself, identify its 25% foreign owner (or owners), and list all reportable transactions during the tax year. The transaction categories include monetary amounts received or paid for sales, rents, royalties, services, commissions, interest, insurance premiums, and other amounts. It also asks for capital contributions and loans, with beginning and ending balances. The form must be accompanied by records sufficient to establish the correctness of the return. Under IRC § 6038A(a), the reporting corporation must maintain records relating to each reportable transaction, including the terms of the transaction and any agreements between the parties. These records must be available in the United States or producible within 60 days of an IRS request. The pattern is remarkably consistent. The pattern is remarkably consistent. A non-US person forms a Wyoming, Delaware, or New Mexico LLC often through a formation agent who handles the state filing but says nothing about federal obligations. The LLC opens a US bank account, receives transfers from its owner, and may or may not conduct business. No one files anything with the IRS. Two or three years later, the owner hears about Form 5472 for the first time and discovers they owe $25,000 per missed year before any tax is even discussed. Another frequent scenario involves LLCs formed to hold US real estate. The property generates no rental income — it is held for personal use or future development so the owner assumes no filing is required. But the purchase itself, funded by a transfer from the foreign owner, is a reportable transaction. The obligation attaches the moment the LLC exists and has a related-party transaction, not the moment it earns income. If you have missed prior-year filings, the path forward is to file the delinquent returns and request penalty abatement under the reasonable cause standard. If you have missed prior-year filings, the path forward is to file the delinquent returns and request penalty abatement under the reasonable cause standard. The IRS considers whether the taxpayer exercised ordinary business care and prudence but was nevertheless unable to comply. Reliance on a professional who failed to advise you of the obligation can support a reasonable cause argument, though it is not guaranteed. First-time penalty abatement (FTA) under IRM 20.1.1.3.6.1 is another avenue if the taxpayer has a clean compliance history for the three preceding years. For LLCs whose first filing year is also the first penalty year, the FTA criteria may be met by default. What does not work is ignoring the notices. An uncontested CP 15 assessment becomes final, and the IRS will begin collection proceedings including offsetting any refunds, filing federal tax liens, and referring the balance to private collection agencies. If you own a US LLC from outside the United States or you formed one and are not certain whether Form 5472 has been filed the most efficient starting point is a scoping call. We will confirm whether the obligation applies, how many years need filing, and what the fixed cost is to bring everything current. No hourly billing, no surprises.
