Form 5472 for a Foreign-Owned US LLC: Who Files, When, and How

If you own a US LLC from outside the United States, you have probably read that a single-member LLC "pays no US tax." That is often true for income tax, but it is not the same as having nothing to file. For tax years beginning in 2017 and later, the IRS requires a US disregarded entity that is wholly owned by a foreign person to file Form 5472, attached to a pro-forma Form 1120, for each tax year in which it has a reportable transaction with its owner or another related party. Money moving between you and the LLC counts, so the year you form the LLC almost always has one. Missing a required filing carries a fixed penalty of $25,000 per form per year.

This guide explains who the rule applies to, what is reported, when it is due, and how to file. It is general information, not individualized tax advice.

Who has to file?

The rule covers a foreign-owned US disregarded entity: a US LLC with one owner, where that owner is a foreign person (an individual who is not a US citizen or resident alien, or a foreign company), and where the LLC has not elected to be taxed as a corporation.

By default the IRS treats a single-member LLC as a disregarded entity, meaning it is ignored for income-tax purposes and its activity belongs to the owner. For the reporting rules in Internal Revenue Code section 6038A, however, the IRS treats that same LLC as if it were a domestic corporation. That is why it must file a corporate information form even though it is not a corporation.

Income is not the test. The filing does not depend on whether the LLC earned income or made a profit, or on whether the owner has a US tax number. It depends on whether the LLC had a reportable transaction during the tax year, explained below.

What is filed?

Two forms go together:

1. Form 5472, the information return of a 25% foreign-owned US corporation. For a disregarded entity, Part V of the form is where the transactions with the foreign owner are reported.
2. A pro-forma Form 1120. The IRS instructions say to complete only the identifying information at the top of Form 1120 (name, address, EIN, and the items the instructions list) and to write "Foreign-owned U.S. DE" across the top. The rest of the corporate return stays blank because the entity has no corporate income tax to compute.

The pro-forma Form 1120 with Form 5472 attached is an information return. It does not by itself create a US income-tax liability, and it does not replace any income-tax filing the owner personally may need to make.

Which transactions are reported?

Form 5472 reports "reportable transactions" between the LLC and its foreign owner and other related parties. For a foreign-owned disregarded entity, Part V of the form covers amounts paid or received in connection with the entity's formation, dissolution, acquisition and disposition, including contributions and distributions. Together with the monetary transactions reported elsewhere on the form, what a foreign-owned LLC typically reports includes:

• contributions to the LLC's capital, including the money you send to open the bank account;
• distributions from the LLC to you;
• loans and repayments in either direction;
• payments for services, rent, or property between you and the LLC; and
• amounts the LLC paid or received on your behalf.

These transactions, not income, decide whether a filing is due. The instructions list exceptions from filing; the first is that the entity had no reportable transactions of the types listed in Parts IV and VI of the form and, for a foreign-owned disregarded entity, also none of the type listed in Part V. Part V is broad: it includes amounts paid or received in connection with the formation, dissolution, acquisition and disposition of the entity, including contributions to it and distributions from it (IRS Instructions for Form 5472).

In practice, any year in which money moves between you and the LLC has a reportable transaction: you put money in, take money out, or pay its costs yourself. The year of formation almost always has one, because the formation costs and the first deposit usually come from the owner. Amounts are reported in US dollars. If you believe a year had genuinely no reportable transactions, get professional advice before assuming no filing is due.

When is it due?

The return is due on the same date as a corporate income-tax return: the 15th day of the fourth month after the end of the tax year. For a calendar-year LLC that is April 15.

You can request an automatic six-month extension by filing Form 7004 by the original due date (IRS; Instructions for Form 7004). The extension gives extra time to file, not extra time to pay any tax that might separately be due: "Form 7004 does not extend the time to pay tax" (IRS Instructions for Form 7004).

How to file

A pro-forma Form 1120 with Form 5472 cannot be filed through the usual corporate e-file route. The IRS instructions direct foreign-owned disregarded entities to send the forms by fax or mail to the address and fax number published in the current Instructions for Form 5472. Check those instructions on the day you file: the mailing address has changed in the past.

Before filing, make sure that:

• the LLC already has its own EIN (the form cannot be filed without one; see how to get an EIN without an SSN);
• the owner's name, address, and country of residence are consistent with the LLC's records; and
• the bank statements and operating agreement support the amounts reported.

What is the penalty?

The penalty for failing to file Form 5472 when due and in the manner prescribed is $25,000 per form per year, and a substantially incomplete form counts as a failure to file. If the failure continues for more than 90 days after the IRS notifies the LLC, an additional penalty of $25,000 applies for 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, Rev. 12/2024, checked on 30 October 2026). The same penalty applies for failing to keep the records that section 6038A requires.

The IRS may abate a penalty for reasonable cause, but that is a request made after the fact, not something to rely on. Filing on time is far cheaper than the alternative.

Records to keep

Section 6038A also requires the LLC to keep records sufficient to establish the accuracy of the return. In practice that means keeping, for at least the statutory period:

• the formation document, operating agreement, and EIN notice;
• bank statements for the LLC and evidence of every transfer to or from you;
• invoices and contracts that explain the LLC's income; and
• a copy of every filed Form 5472 and pro-forma Form 1120.

These are the same documents banks and payment providers ask for, so one organized company file serves both purposes. Records a foreign-owned US LLC should keep, and for how long sets out the retention periods and where the records may be held.

What this guide does not cover

Form 5472 is one filing among several that may apply. It does not cover:

• US income tax on the owner. Whether you owe US income tax depends on whether the LLC's income is effectively connected with a US trade or business, on tax treaties, and on your own residence. That is a separate analysis; start with Foundlie's US LLC tax guide and speak with a professional.
• Multi-member LLCs. An LLC with two or more owners is taxed as a partnership by default and files Form 1065 with Schedules K-1, not Form 5472 with a pro-forma 1120.
• LLCs that elected corporate tax treatment. Those taxed as C corporations file a full Form 1120 income tax return. If at least 25% foreign-owned, they generally also file Form 5472 when they have reportable related-party transactions, subject to the IRS exceptions. LLC vs S-Corp vs C-Corp explains what that election changes and why Subchapter S is closed to non-resident alien owners.
• State filings. Annual reports and state taxes are handled separately by each state; see our state comparison, and the annual compliance calendar for a foreign-owned US LLC for every recurring deadline in one place.
• FinCEN beneficial ownership reports. BOI reporting is a separate federal regime, and an LLC formed in a US state no longer files one; BOI reporting in 2026 explains who still does.

Build the company file first

Everything in this guide is easier when the LLC is formed cleanly, the EIN is issued to the LLC itself, and the owner's contributions and withdrawals are visible in a dedicated business account from day one. Foundlie helps with forming the US company and organizing those records; review the formation packages and pricing or contact us if you are unsure which route fits.
