Form 5472 for Foreign-Owned LLCs: Transactions and Filing Rules

Understand when reportable related-party transactions trigger Form 5472, the pro forma 1120, IRS filing methods, deadlines and penalty conditions.

By OpenStates Team ·

A foreign-owned US disregarded entity must file Form 5472 attached to a pro forma Form 1120 for a year with reportable related-party transactions. Owner contributions, distributions, loans and payments can qualify, including formation funding with zero revenue. Review each tax year separately: a prior formation contribution does not itself create a transaction in every later year. Other classifications and filing exceptions require separate analysis. When a required Form 5472 is missing, late or substantially incomplete, the IRS can assess a $25,000 penalty. Continued failure after 90 days following IRS notice can lead to an additional $25,000 for each related party for each 30-day period or part thereof. Reasonable-cause relief depends on the facts; neither zero revenue nor an informal checklist guarantees relief. The checklist below explains records, the pro forma cover return and filing methods; it does not determine every business’s tax obligations. Further reading: single-member US LLC

Form 5472 filing checklist (8 steps)

Use this checklist to organize an annual filing review. Completing a checklist cannot certify an accurate return or guarantee that no penalty applies; reconcile the records and follow the current IRS instructions.

Confirm your LLC is a foreign-owned single-member disregarded entity — one non-US owner, no S-corp or C-corp election filed.
Get an EIN before filing — Form 5472 cannot be filed without an Employer Identification Number on the LLC.
List every reportable transaction for the tax year, including the initial capital contribution, owner distributions, and loans.
Prepare a pro forma Form 1120 with only the header fields completed and "Foreign-owned U.S. DE" written across the top margin.
Complete Form 5472 Parts I–VI — reporting corporation, foreign owner, related party, monetary and non-monetary transactions.
Attach Form 5472 behind the pro forma 1120 as a single stapled package; do not file them separately.
Mail or fax by April 15 (or October 15 with a Form 7004 extension) to IRS Ogden, UT or fax +1 (855) 887-7737.
Save certified-mail receipt or fax confirmation for six years — this is your only proof of timely filing if the IRS challenges you.

What is Form 5472?

Form 5472 is an information return the IRS uses to track "reportable transactions" between a US entity and its foreign owner or related parties. It does not calculate tax — it's purely informational. The point is to give the IRS visibility into money flowing between you (the foreign owner) and your US LLC.

Foreign-owned US disregarded entities have been treated as corporations for the limited section 6038A reporting rules for the applicable tax years beginning in 2017. That treatment does not make them ordinary corporate income taxpayers. Form 5472 filing still depends on reportable transactions and the instructions’ exceptions.

Who has to file it?

You must file Form 5472 + a pro-forma 1120 if all of these are true:

Your US LLC is a single-member LLC (one owner)
The owner is a foreign person (non-US individual, foreign corporation, etc.)
The LLC is treated as a disregarded entity for US tax purposes (the default for single-member LLCs)
There were any reportable transactions during the year — including the formation contribution itself

A formation contribution can create a filing duty in the formation year. Contributions, distributions or other related-party activity in later years can create later duties. Review each year’s transactions rather than treating the original contribution as a perpetual filing trigger.

Multi-member LLCs: different rules

A multi-member LLC is generally taxed as a partnership by default and may need Form 1065, partner reporting and withholding. Form 5472 is not limited to single-member LLCs: qualifying 25% foreign-owned domestic corporations and other reporting corporations can also have obligations. An LLC electing corporate taxation needs a fresh analysis.

What counts as a "reportable transaction"?

Capital contributions from the foreign owner to the LLC
Distributions from the LLC to the foreign owner
Loans between the LLC and the foreign owner (in either direction)
Payments for services between the LLC and the foreign owner or related parties
Rent, royalties, interest paid between the LLC and related foreign parties

Customer revenue from unrelated third parties is not a reportable transaction for 5472 purposes — only money flowing between the LLC and you (the owner) or other related parties counts. That confuses a lot of first-time filers: a Stripe payout from a US customer doesn't go on Form 5472, but a $100 capital contribution from you does.

Form 5472 deadlines and extensions

Form 5472 + pro-forma 1120 is due by April 15 for calendar-year LLCs. You can file Form 7004 to get an automatic 6-month extension to October 15. Note: extending doesn't push back any tax owed (typically zero for foreign-owned disregarded entities), but it does extend the filing deadline.

File Form 7004 by April 15 — late extensions are not accepted. If your LLC uses a fiscal year other than the calendar year, the deadline is the 15th day of the 4th month after year-end. Most non-resident-owned LLCs use the calendar year by default, so April 15 / October 15 is the cycle to remember.

The $25,000 Form 5472 penalty (and how it compounds)

When a required Form 5472 is missing, late or substantially incomplete, the IRS can assess a $25,000 penalty. Continued failure after 90 days following IRS notice can lead to an additional $25,000 for each related party for each 30-day period or part thereof. Reasonable-cause relief depends on the facts; neither zero revenue nor an informal checklist guarantees relief.

The IRS instructions specify a $25,000 penalty for failure to file a required Form 5472 and for certain record-maintenance failures. Revenue is not the filing trigger: a zero-revenue company with reportable transactions can still owe the return. Do not infer an obligation or a penalty from dormancy alone.

If a required filing was missed, consult a tax professional promptly about filing the return, responding to notices and documenting any reasonable-cause request. Relief is case-specific; hiring a CPA does not itself establish reasonable cause and an IRS notice does not automatically eliminate all defenses.

Form 5472 instructions: step-by-step

Here are the detailed Form 5472 instructions that expand on the checklist above. Work through each step in order.

Prepare the pro forma Form 1120 using the name and address plus items B and E on the first page as specified in the current Form 5472 instructions. Write “Foreign-owned U.S. DE” across the top. Do not complete a normal corporate income and deduction return merely because this cover form is required.
Attach Form 5472 and complete the applicable parts. Parts I–III identify the reporting corporation, foreign shareholder and related party. Part V covers additional transactions of a foreign-owned US DE, including formation contributions and distributions. Part VI addresses nonmonetary and less-than-full-consideration transactions. Do not put a capital contribution on an arbitrary purchase line in Part IV.
Round amounts to whole US dollars. Convert any non-USD transactions using the spot rate on the transaction date or a reasonable annual average rate. Be consistent across years.
Mail or fax the package. Form 5472 must be mailed or faxed — it cannot be e-filed as a standalone. Mail to: Internal Revenue Service, 1973 Rulon White Blvd., M/S 6112, Attn: PIN Unit, Ogden, UT 84201, USA. Fax: +1 (855) 887-7737.
Keep proof of filing. Certified mail receipt or fax confirmation. The $25,000 penalty turns on whether you can prove you filed. Keep records for at least six years — the IRS statute of limitations on 5472 penalties does not begin running until the form is filed.

Pro forma 1120: what the IRS actually wants

"Pro forma" trips up almost everyone. The IRS wants the 1120 form as a structural cover sheet, not as a real tax return. Here's exactly what to fill in:

Top margin: handwrite or type "Foreign-owned U.S. DE"
Name and address block: the LLC's legal name and US registered address
Box B (EIN): the LLC's EIN
Item C (formation date): the special DE instructions require only name, address and items B and E on the first page; do not treat C as an additional required field.
Item D (assets): not among the fields required by the special pro forma DE instructions; do not invent a zero asset amount.
Box E: check "Initial return" if it's the first year
Tax year: calendar year or fiscal year
Signature: follow the current special DE instructions and your preparer’s requirements; do not invent ordinary corporate-return fields for the cover.

Leave every income, deduction, and tax line blank. The 5472 attached behind it is the actual substantive filing — the 1120 is just the envelope the IRS requires.

Foreign-owned single-member LLC: annual filing review

Form 5472 is the centerpiece, but your full foreign-owned single-member LLC tax filing obligations usually include:

Federal: Form 5472 with pro forma 1120 for years with reportable related-party transactions; due date and extensions follow the IRS instructions.
State annual obligations: Wyoming $60 or 0.0002 × Wyoming assets, whichever is greater; Delaware LLC annual tax $400; other states assessed separately.
Companies created in the United States, including foreign-owned US LLCs, are exempt from federal FinCEN BOI reporting under the final rule issued August 11 and effective August 14, 2026. A company created under foreign law and registered in a US state is different and may still have a reporting obligation. Banks and state authorities may still request ownership information.
1040-NR and withholding: determine the foreign owner’s US trade or business, ECI, FDAP and return exceptions, including income earned through a disregarded LLC.
State income tax: only if the LLC has nexus in a state that taxes pass-throughs
Sales tax: if you sell physical goods or taxable services to US customers above state economic-nexus thresholds

No-US-office status does not settle federal income tax or withholding. Review services, inventory, agents, royalties, investments and treaties as well as reportable owner transactions. State income and sales tax can have different nexus rules.

Common mistakes

Thinking you don't have to file because the LLC made no money. A capital contribution in the tax year can trigger the obligation; review each year separately.
Filing only the 1120 without the 5472. Both are required.
Forgetting that you can't e-file it. It must be mailed or faxed.
Missing the April 15 deadline. File Form 7004 if you need more time.
Using the wrong EIN or no EIN. The LLC needs its own EIN — your ITIN or personal tax ID doesn't substitute.
Skipping Parts II and III when you're both the owner and related party. You usually still fill out both.
Not keeping proof of mailing. Without certified mail or fax confirmation, you can't defend against the penalty.

Do you also need to pay US tax?

US tax is not determined by the absence of an office alone. A single-member LLC is generally disregarded unless it elects corporate taxation, but the owner may owe US tax on effectively connected income (ECI) or US-source fixed, determinable, annual or periodical (FDAP) income. FDAP is generally subject to 30% gross withholding unless a treaty or other rule reduces or removes it; ECI is generally taxed on a net basis. Home-country treatment depends on local law, entity classification and treaty relief, not a universal rule that every owner always pays tax at home. Form 5472 is informational, not a determination that the owner owes no tax.

Frequently asked questions

Who has to file IRS Form 5472?

What is the penalty for not filing Form 5472?

When is Form 5472 due?

When filing applies, Form 5472 attached to the pro forma Form 1120 is generally due April 15 for a calendar-year foreign-owned US disregarded entity, subject to applicable weekend, holiday or relief rules. A timely Form 7004 can extend the filing deadline by six months. A filing extension does not extend the deadline for any tax owed; tax liability requires a separate review.

Do I have to file Form 5472 if my LLC made no money?

Zero revenue does not remove the duty when reportable related-party transactions occurred in that year. Formation funding can qualify, but a previous year’s contribution is not a new transaction by itself. Review records and filing exceptions each year.

Can I e-file Form 5472?

For foreign-owned US disregarded entities, the current IRS instructions prohibit electronic filing of Form 5472. Fax or mail Form 5472 with the pro forma 1120 using the dedicated IRS address or fax number in the instructions. Other reporting corporations may follow different electronic-filing rules.

What is a pro forma 1120 and why do I need one?

The pro forma Form 1120 is the required cover attached to Form 5472 for a foreign-owned US DE when filing applies. The IRS requires the entity name and address and items B and E on page one, with “Foreign-owned U.S. DE” written across the top. It is not a full ordinary corporate income tax return.

Does Form 5472 mean my LLC owes US tax?

US tax is not determined by the absence of an office alone. A single-member LLC is generally disregarded unless it elects corporate taxation, but the owner may owe US tax on effectively connected income (ECI) or US-source fixed, determinable, annual or periodical (FDAP) income. FDAP is generally subject to 30% gross withholding unless a treaty or other rule reduces or removes it; ECI is generally taxed on a net basis. Home-country treatment depends on local law, entity classification and treaty relief, not a universal rule that every owner always pays tax at home. The informational return does not calculate the owner’s income tax.

Can I file Form 5472 myself or do I need a CPA?

You can legally file it yourself if you have an EIN and clean books. Most non-resident owners hire a US tax preparer ($250–$500) because a single mistake risks the $25,000 penalty. The cost of a CPA is trivial compared to the downside.

What if I missed last year's Form 5472?

Consult a qualified preparer promptly, file required late information and preserve records. Respond to any IRS notice on time and assess whether a documented reasonable-cause request is appropriate. Relief is not guaranteed and receipt of a notice does not automatically remove every defense.

Do multi-member foreign-owned LLCs file Form 5472?

A multi-member LLC is generally a partnership by default, with partnership returns and possible withholding. An election to be taxed as a corporation can change the analysis, and qualifying 25% foreign-owned reporting corporations can also need Form 5472.
