Form 5472 & the $25,000 Penalty: What Foreign-Owned LLCs Must File

What is Form 5472, and why do foreign-owned LLCs have to file it?

Form 5472 is the IRS “Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business.” Since 2017, a US LLC wholly owned by a foreign person is treated as a corporation for limited reporting purposes and must file Form 5472 every year, even with no income. (IRS — About Form 5472)

The legal hook is Treasury Regulation §1.6038A-1, which the IRS finalized to close a transparency gap. Before 2017, a single-member LLC (“disregarded entity”) owned by a non-resident was largely invisible to the IRS because disregarded entities file no return of their own. Final regulations changed that: “If a foreign person wholly owns a domestic disregarded entity (DE), the domestic DE is treated as a domestic corporation separate from its owner for the limited purposes of the requirements under section 6038A.” The rule applies to tax years beginning on or after January 1, 2017, and ending on or after December 13, 2017. (IRS — Instructions for Form 5472)

The purpose is purely informational: Form 5472 reports “reportable transactions” between your LLC and its foreign owner (and other related parties). It does not itself calculate or collect tax — but failing to file it carries one of the steepest information-return penalties in the US tax code, starting at $25,000.

Do I need to file Form 5472 for a single-member LLC?

Yes — if your US single-member LLC is owned by a non-US person and is treated as a disregarded entity, you must file Form 5472 attached to a pro-forma Form 1120 every year, even with zero income, zero employees, and no US activity, provided at least one reportable transaction occurred during the year. The forming or funding of the LLC alone usually counts. (IRS — Instructions for Form 5472)

The IRS instructions are explicit that this is a new return obligation for an entity that previously filed nothing: a foreign-owned US DE “will now be required to file a pro forma Form 1120, U.S. Corporation Income Tax Return, with Form 5472 attached by the due date (including extensions) of that Form 1120.” You write “Foreign-owned U.S. DE” across the top of the Form 1120, fill in only the LLC’s name, address, and EIN, and leave the income/deduction lines blank — the 1120 is just a cover sheet for the 5472.

Three conditions trigger the filing, all of which must be true:

1. The entity is a US LLC (or other domestic eligible entity).
2. It is a disregarded entity — by default, a single-member LLC that has not elected corporate taxation.
3. It is wholly owned, directly or indirectly, by one foreign person (an individual, corporation, partnership, trust, or estate that is not a US person).

There is no minimum-income or minimum-transaction-size exemption. An LLC that earned nothing all year still files if a reportable transaction — such as the owner wiring in startup capital — took place. (IRS — Instructions for Form 5472)

What counts as a “reportable transaction” on Form 5472?

A reportable transaction is virtually any monetary or property exchange between your LLC and a related party — most commonly the foreign owner. It includes obvious items like sales, loans, rents, and royalties, but critically also capital contributions into the LLC and distributions out of it, including the money you use to form and fund the company. (IRS — Instructions for Form 5472)

This is the trap that catches most non-resident founders who assume “no income = no filing.” The IRS defines reportable transactions in two parts. Part IV covers transactions “for which monetary consideration (including U.S. and foreign currency) was the sole consideration paid or received” — sales, rents, interest, and similar. Part V broadens it to other transactions, expressly including “amounts paid or received in connection with the formation, dissolution, acquisition, and disposition of the entity, including contributions to, and distributions from, the entity.” (IRS — Instructions for Form 5472)

In practice, that means the following common founder activities are reportable:

• Wiring your own money into the LLC’s US bank account to capitalize it (contribution).
• Paying the LLC’s formation, registered-agent, or state filing fees personally on its behalf.
• Taking money out of the LLC for personal use (distribution).
• Lending money to or borrowing money from your own LLC.
• The LLC paying you, or you paying the LLC, for any goods or services.

Because nearly every newly-formed foreign-owned LLC has at least a funding event in its first year, the practical reality is that most foreign-owned single-member LLCs must file in their very first year and every year thereafter while they have related-party activity. When in doubt, the conservative position is to file.

How much is the Form 5472 penalty? ($25,000 and counting)

The penalty for failing to file a complete and correct Form 5472 by the due date is $25,000 per form, per year. If you don’t file within 90 days after the IRS notifies you, an additional $25,000 applies for each 30-day period (or part of one) that the failure continues — and the IRS states plainly: “There is no maximum penalty amount.” (IRS — International information reporting penalties)

The IRS instructions confirm both tiers. The initial assessment: “A penalty of $25,000 will be assessed on any reporting corporation that fails to file Form 5472 when due and in the manner prescribed.” The continuation penalty: “If the failure continues for more than 90 days after notification by the IRS, an additional penalty of $25,000 will apply. This penalty applies with respect to each related party for which a failure occurs for each 30-day period (or part of a 30-day period) during which the failure continues after the 90-day period ends.” (IRS — Instructions for Form 5472)

Two details make this penalty especially dangerous for non-residents:

• A substantially incomplete form counts as a failure to file. Filing a sloppy or partial 5472 is treated the same as not filing at all, so a careless return can trigger the full $25,000.
• The penalty is per form, per year, with no ceiling. Because the continuation penalty has no statutory maximum, a long-ignored IRS notice can compound into six figures. This is a $25,000-minimum penalty, not a maximum.

How the penalty escalates after an IRS notice

All amounts above are from the IRS Form 5472 instructions and the IRS international-information-reporting-penalties page. (IRS — Instructions for Form 5472; IRS — International information reporting penalties)

A reasonable-cause exception exists: the penalty does not apply to a failure that is “due to reasonable cause and not willful neglect,” but you must affirmatively show it, and “not knowing about the requirement” is a weak argument that the IRS frequently rejects. The far cheaper path is simply to file on time.

Who must file, when, and how? (the rules at a glance)

A foreign-owned single-member LLC files Form 5472 with a pro-forma Form 1120, by mail or fax only, due the 15th day of the 4th month after year-end — about April 15 for calendar-year LLCs. A multi-member LLC instead files Form 1065. The table below maps each entity type to its form, deadline, and penalty exposure. (IRS — Instructions for Form 5472)

The corporate deadline is set by statute: a corporation generally files “by the 15th day of the 4th month after the end of its tax year,” which is April 15 for calendar-year taxpayers (the next business day if the 15th is a weekend or holiday). A fiscal-year LLC ending June 30 has a different date. (IRS — Instructions for Form 1120) The partnership deadline for multi-member LLCs is the 15th day of the 3rd month — about March 15. (IRS — About Form 1065)

You can extend the deadline six months with Form 7004, filed by the original due date. For a disregarded-entity 5472 filer, the IRS says to enter the Form 1120 code on Form 7004, Part I, line 1.

Can I e-file Form 5472? (No — mail or fax only)

No. A foreign-owned US disregarded entity cannot e-file Form 5472. The IRS requires the pro-forma Form 1120 with Form 5472 attached to be submitted by fax to 855-887-7737 (at 300 DPI or higher) or by mail to a special Ogden, Utah service address — not the normal Form 1120 addresses. (IRS — Instructions for Form 5472)

This is a frequent and expensive mistake: founders assume that because everything else (the EIN, the bank account) is online, the 5472 must be too. It is not. The IRS instructions state directly: “If you are a foreign-owned U.S. DE, you cannot file Form 5472 electronically.” They must use the dedicated channel below, and “do not use the mailing addresses provided in the Instructions for Form 1120.”

The two filing channels for a foreign-owned DE:

• Fax: 855-887-7737 (scan at 300 DPI or higher).
• Mail: Internal Revenue Service, 1973 Rulon White Blvd, M/S 6112, Attn: PIN Unit, Ogden, UT 84201.

Write “Foreign-owned U.S. DE” across the top of the Form 1120 (and across Form 7004 if you’re extending). Fax is the practical choice for non-residents because it gives an immediate transmission confirmation and avoids international mail delays. (IRS — Instructions for Form 5472)

What does a foreign-owned single-member LLC actually have to do each year? (Checklist)

Each year, a foreign-owned single-member LLC must prepare a pro-forma Form 1120, attach a completed Form 5472 reporting its related-party transactions, and mail or fax both to the IRS Ogden address by its deadline (≈ April 15). The numbered steps below walk through the full annual compliance cycle. (IRS — Instructions for Form 5472)

1. Confirm you have an EIN. Form 5472 and the pro-forma 1120 both require the LLC’s Employer Identification Number; you cannot file without one.
2. Gather the year’s reportable transactions. Total up contributions, distributions, loans, and any payments between you (and other related parties) and the LLC — in US dollars.
3. Complete the pro-forma Form 1120. Fill in only the LLC’s name, address, and EIN; write “Foreign-owned U.S. DE” across the top; leave income and deduction lines blank.
4. Complete Form 5472. Identify the reporting entity (Part I), the 25% foreign owner (Part II), related parties, and report the transactions in Parts IV/V.
5. Attach the 5472 to the 1120. The 5472 is filed with the pro-forma 1120, not on its own.
6. File by mail or fax to Ogden — never e-file — by the deadline (15th day of the 4th month after year-end; ≈ April 15 for calendar-year LLCs).
7. Extend if needed. File Form 7004 by the original due date for a six-month extension; the extension is of the filing deadline.
8. Keep records. §1.6038A-3 requires maintaining records sufficient to establish the accuracy of the return; failing to maintain records is itself penalized.
9. Repeat every year the LLC exists and has related-party activity — there is no “dormant LLC” exemption while reportable transactions occur.

EIN.LLC forms US LLCs and obtains EINs for non-resident founders (typically $399 plus the state fee, no SSN required, in about 3–5 business days), which is what gives a new foreign-owned LLC the EIN it needs before any Form 5472 can be filed. EIN.LLC is a filing service, not a law or tax firm, so the annual 5472 itself is generally handled by a US tax preparer or accountant.

FAQ

Do I have to file Form 5472 if my LLC made no money? Yes, in almost all cases. There is no income threshold. If a reportable transaction occurred — and merely funding or paying the formation costs of the LLC usually counts — you must file Form 5472 with a pro-forma Form 1120, even on zero revenue.

What is the minimum penalty for not filing Form 5472? $25,000 per form, per year. If you ignore an IRS notice for more than 90 days, an additional $25,000 applies for each 30-day period afterward, and the IRS states there is no maximum penalty amount.

Is forming and funding my LLC a reportable transaction? Yes. The IRS instructions list amounts paid or received in connection with the formation of the entity and contributions to the entity as reportable. Wiring your own capital into the LLC is the most common first-year reportable transaction.

Can I e-file Form 5472 for my single-member LLC? No. A foreign-owned US disregarded entity cannot file Form 5472 electronically. You must fax it to 855-887-7737 or mail it to the IRS Ogden, Utah address — not the normal Form 1120 address.

When is Form 5472 due? On the 15th day of the 4th month after your LLC’s tax-year end — about April 15 for calendar-year LLCs (next business day if that’s a weekend or holiday). You can extend six months with Form 7004 filed by the original due date.

My LLC has two or more owners — do I file Form 5472? Generally no. A multi-member LLC defaults to a partnership and files Form 1065 instead of the 5472/1120 package. (A 25%-foreign-owned LLC that elected to be taxed as a C-corporation does file Form 5472 with a real Form 1120.)

Does EIN.LLC file Form 5472 for me? EIN.LLC forms the LLC and obtains the EIN you need before any 5472 can be filed (about $399 plus the state fee, no SSN, ~3–5 business days). It is a filing service, not a tax firm; the annual Form 5472 itself is typically prepared by a US accountant or tax preparer.
