Taxes and reporting for a foreign-owned LLC

A US LLC is not a tax strategy. For a single-member LLC owned by a non-US person, the US federal income tax treatment is usually transparent: the LLC is disregarded, and the owner is taxed on the income. But the LLC still has an information-reporting obligation that catches many first-time founders — and the penalty is $25,000.

Why a “disregarded” LLC still files

For US federal income tax, a single-member LLC owned by a foreign person is generally a disregarded entity. The IRS treats the owner and the LLC as one taxpayer for income tax purposes. That does not make the LLC invisible. Regulations under section 6038A treat a foreign-owned US disregarded entity as a corporation for the limited purpose of the Form 5472 reporting rules.

The result is a hybrid filing: a pro forma Form 1120 that contains only the entity's name and address and a few items, with Form 5472 attached. The form reports reportable transactions between the LLC and its foreign owner or other related parties — including contributions, distributions and some payments. Do not assume “no profit” means “no form”. The obligation can exist even when the LLC had no income.

When is it due?

Form 5472 is filed with the pro forma Form 1120 by the due date of that return, including extensions. For a calendar-year company, the Form 1120 due date is generally the 15th day of the fourth month after year-end — 15 April — but confirm the current Form 1120 instructions for your year and entity. An extension is requested on Form 7004; the IRS instructions for foreign-owned disregarded entities describe the special procedure and the fact that the form must be faxed or mailed, not filed electronically.

The foreign-owned disregarded entity cannot file Form 5472 electronically. The instructions give a dedicated mailing address and say “Foreign-owned U.S. DE” should be written across the top of the Form 1120. If you use a tax preparer, confirm that they have handled this specific filing before; it is not the same as a normal 1120 or a partnership return.

What counts as a reportable transaction?

The form asks about transactions between the LLC and foreign related parties, including the foreign owner. Contributions to the LLC, distributions from the LLC, loans, and amounts paid or received for goods or services can be reportable. The instructions for Part IV, Part V and Part VI set out the categories and exceptions. The safe approach is to keep a clean record of every movement of money between you and the LLC, with dates, amounts and a short description.

This is also why commingling personal and business money is a bad idea. It weakens the liability shield, and it makes the Form 5472 harder to complete accurately. Use a separate business account and label owner contributions and draws clearly in your bookkeeping.

BOI in 2026: the rule changed again

FinCEN's final rule, announced on 11 August 2026 and effective 14 August 2026, makes permanent the exemption for US companies from beneficial ownership information reporting. Under the current rule, a company formed in the United States — including a Wyoming, Delaware, New Mexico or Florida LLC — is not a reporting company and does not file a BOI report. Only certain foreign companies registered to do business in the US must report, and they do not report US-person beneficial owners.

That is a reversal of the 2024 message that every small LLC had to file. If you formed a US LLC in 2024 and filed a BOI report, you do not need to update it as a US company under the current rule, and a US person with a FinCEN ID does not need to update that ID. If you registered a foreign company to do business in the US, the foreign-company rule may still apply; check FinCEN's current guidance rather than a provider's upsell page. Source: FinCEN.

W-8BEN and W-8BEN-E

US payers and banks often ask a foreign-owned entity for a W-8 form to document foreign status and claim treaty benefits where applicable. An individual owner may provide Form W-8BEN; an entity may provide Form W-8BEN-E. The right form depends on who is receiving the payment and what the payer needs. These forms are not a substitute for Form 5472, and they do not by themselves determine tax residency.

If a US customer withholds tax from a payment, the withholding rate and the documentation matter. A treaty may reduce withholding on certain payments, but it does not eliminate the need to report income where you live. Keep copies of the forms you sign and note the date and the payer.

State annual reports are separate

Your federal filing does not satisfy the state. Wyoming wants an annual report and a minimum $60 license tax; Delaware wants a $400 annual tax by 1 June; Florida wants a $138.75 annual report by 1 May; New Mexico has no annual report. Missing the state filing can lead to penalties, loss of good standing and administrative dissolution. The state guide lists the deadlines.

Sales tax, payroll and other US taxes

Federal income tax and Form 5472 are only part of the picture. If you sell taxable goods or services into a US state, economic nexus rules may require sales-tax registration and collection once you cross that state's threshold. If you hire US employees, payroll taxes and registrations apply. If you elect S-corp status, payroll and reasonable-compensation rules apply. None of these is automatic for a European-owned LLC with no US activity, but none should be assumed away.

A US accountant can map the thresholds for the states where you have customers, inventory or staff. The cost of that advice is usually small compared with a penalty or a back-tax assessment.

The European side: your home country still taxes you

A US LLC does not move your tax residence. If you live in the Netherlands, Poland, Germany or another EU country, your country of residence generally taxes your worldwide income, and it may treat the LLC differently from the US. Two concepts come up repeatedly:

• Place of effective management: if the LLC is managed from your kitchen table in Europe, your home country may treat it as a resident company or look through it. The US view and the local view can differ.
• CFC-type rules: controlled foreign company rules can attribute undistributed profits to a resident shareholder in some circumstances. Whether they apply depends on ownership, the entity's classification and the local law.

There is also VAT. A US LLC selling services to EU customers may have EU VAT registration and reporting obligations, and the place-of-supply rules are not the same as the US sales-tax rules. Do not assume that a US entity removes you from EU VAT. Take advice from a tax adviser in the country where you live, and give them the facts: who owns the LLC, where decisions are made, where the work is done, and who the customers are.

A minimum record-keeping routine

• Keep the formation documents, EIN letter and operating agreement in one folder.
• Record every owner contribution and distribution with a date, amount and purpose.
• Keep the LLC's bank statements separate from personal accounts.
• Note any payments between the LLC and a foreign related party.
• Put the Form 5472 deadline and the state annual deadline in the same calendar.
• Keep the working papers you used to prepare the return; the IRS can ask about reportable transactions.

What this page is not

This is general information, not tax advice. It does not create a tax position you can rely on, and it cannot tell you whether your LLC has a US trade or business, whether a treaty applies, or how your home country will classify the entity. Those questions need a qualified adviser who has your facts. Source links for the federal rules are in the sources section below.
