Foreign-Owned US LLC Filing Checklist (2026)

A foreign-owned U.S. single-member LLC with a reportable related-party transaction generally has a federal Form 5472 filing package: Form 5472 attached to a pro forma Form 1120. It also needs to meet the ongoing requirements of its formation state. Other filings—including an FBAR, an income-tax return, or a withholding return—depend on the entity, account, income, and payment facts; do not treat the owner's non-U.S. status as a complete answer for the LLC.

This is a compliance map, not a substitute for advice on income tax, withholding, or account reporting. If Form 5472 is the item you need help preparing, see current service options and pricing.

The checklist at a glance

Do I have to file Form 5472?

A foreign-owned U.S. disregarded entity is a domestic disregarded entity wholly owned by a foreign person. For the limited section 6038A reporting rules, it is treated as a corporation. It generally files Form 5472 when it had a reportable transaction with a related party. The IRS instructions define the transactions and explain that a DE with no reportable Part IV, V, or VI transactions does not have this filing requirement.

Common owner-to-LLC movements may be reportable, but classification turns on the actual facts. Keep an itemized ledger and source documents for contributions, distributions, loans, reimbursements, services, and noncash transfers. Unrelated customer revenue is not automatically a related-party transaction merely because it entered the LLC's account; a later owner transfer can raise a separate question. See worked transaction examples.

For a foreign-owned U.S. DE, Form 5472 is attached to a pro forma Form 1120. The IRS instructions require the entity's name and address and items B and E on page 1 of that Form 1120, with “Foreign-owned U.S. DE” across the top. The entity cannot e-file this Form 5472 package. It may fax at 300 DPI or higher to 855-887-7737 or mail to Internal Revenue Service, 1973 Rulon White Blvd, M/S 6112 Attn: PIN Unit, Ogden, UT 84201.

The IRS states that a $25,000 penalty may apply for failure to file when due and in the prescribed manner, a substantially incomplete Form 5472, or failure to maintain required records. That is not an automatic result of every mistake, and a paid service cannot eliminate the risk.

Does the LLC need an FBAR?

Possibly. Check the LLC separately from its owner. The IRS says a U.S. person includes a U.S. limited liability company. An LLC may have an FBAR obligation if it has a financial interest in, or signature or other authority over, one or more financial accounts located outside the United States and the aggregate value exceeds $10,000 at any time in the calendar year.

The LLC's disregarded status for federal income tax does not by itself answer the Bank Secrecy Act question. Nor does a non-U.S. owner's status make the LLC non-U.S. for FBAR purposes. Confirm the account holder, institution and actual account location from the account documents; a product brand, USD balance, or card location is not enough. The IRS FBAR overview is the starting point. Seek an FBAR-qualified professional for unclear account arrangements or any possible filing.

For the account-location matrix and records worksheet, see our foreign-owned U.S. LLC FBAR guide.

Does the LLC still file BOI?

For an entity created in the United States, no under the current FinCEN rule. FinCEN's current BOI page says U.S.-created entities and their beneficial owners are exempt. Certain entities formed under foreign law that register to do business in the United States can still be reporting companies, so check FinCEN directly if the LLC was formed abroad.

What state filing does the LLC need?

There is no single state rule. Check the formation state's official business-entity portal for the LLC's current status, filing type, due date, fee, and whether a report or tax is required. For example, Wyoming's official guidance describes an annual-report/license-tax workflow, Delaware's states that LLCs pay annual tax but do not file an annual franchise-tax report, and Florida's describes its annual-report cycle. These examples are not a substitute for checking your own state and year.

Registered-agent renewals are private service contracts, not a federal tax filing. Keep them separate from the state record and federal Form 5472 package.

Also check states where the LLC is registered or conducts business; formation-state compliance alone does not settle income-tax, sales-tax, or other nexus obligations.

What else might apply?

Income tax, Forms 1040-NR or 1120-F, Forms 1099 or 1042-S, payroll filings, sales-tax registration, and state income-tax returns depend on facts that this checklist cannot resolve: who earned the income, where work was performed, U.S. trade-or-business and treaty questions, payments made, employees, property, and state nexus. “No U.S. income tax due” is not the same as “no U.S. filing obligation.” Ask a qualified adviser before relying on either conclusion.

Annual compliance cycle

If you pay overseas service providers, use our foreign-contractor documentation and reporting guide to separate the contractor's status from the Form 5472 related-party test.

1. After year-end: reconcile every related-party transaction to a ledger and source documents.
2. Before the regular federal due date: prepare Form 5472 with its pro forma Form 1120, or submit Form 7004 using the special DE instructions if an extension is needed.
3. Before delivery: use the current IRS address/fax instructions and retain a copy of the exact package and objective mailing or transmission evidence.
4. On the formation-state schedule: check the entity's official record and complete any current state filing or payment.
5. During the year: reassess FBAR, withholding, and tax-return questions if accounts, payments, locations, or business operations change.

Frequently asked questions

Does a foreign-owned U.S. LLC with no income have to file anything?

It can. Form 5472 is about reportable related-party transactions, not simply income. State obligations and account reporting are separate questions.

Can I e-file the Form 5472 package for a foreign-owned U.S. DE?

No. The IRS instructions say this filer cannot e-file Form 5472. Use the dedicated fax or mailing route described above.

Does the foreign owner personally need an FBAR for the LLC's U.S. bank account?

Do not assume so from this checklist. The account holder, location, owner status, and authority need separate analysis. A U.S. bank account is not automatically a foreign financial account, while a U.S. LLC can have an LLC-level test for an account located outside the United States.

Do I need an ITIN just to file Form 5472?

Not necessarily. The Form 5472 instructions address an FTIN and reference ID number for foreign owners; an ITIN is a separate eligibility question. See when an ITIN is required.

The bottom line

Start with the Form 5472 package if the LLC had reportable related-party activity, then separately check formation-state obligations, BOI status, FBAR account facts, and any tax or withholding triggers. See current Form5472 Prep options for the supported Form 5472 preparation workflow.
