Question: What tax forms does a foreign-owned U.S. business have to file?

Foreign-Owned U.S. Business Tax Reporting: The Forms and Penalties to Know

A foreign-owned U.S. business often owes information returns like Form 5471, Form 5472, the FBAR, and FIRPTA withholding, each with its own steep penalty. Here is how these cross-border filings fit together and who must file them.

Quick answer

A foreign-owned U.S. business usually faces a second set of filings on top of the income tax return: information returns that report cross-border ownership and money movement. The main ones are Form 5471 for U.S. owners of foreign corporations, Form 5472 for a 25% foreign-owned U.S. corporation, the FBAR for foreign financial accounts, and FIRPTA withholding when a foreign owner sells U.S. real estate. Each carries its own penalty even when no tax is due.

Key points

  • Information returns report cross-border ownership and accounts; they are separate from your income tax return and are penalized on their own
  • U.S. officers, directors, and shareholders of a foreign corporation file Form 5471, which carries a $10,000 penalty per foreign corporation for a missed year
  • A U.S. corporation that is 25% foreign-owned, or a foreign corporation doing business in the U.S., files Form 5472, with a $25,000 penalty for failing to file
  • Foreign financial accounts above $10,000 in aggregate trigger the FBAR (FinCEN Form 114), and Form 8938 can apply on top of it
  • Selling U.S. real estate as a foreign owner generally means 15% FIRPTA withholding, reported on Form 8288

What tax forms does a foreign-owned U.S. business have to file?

A foreign-owned U.S. business almost always has two parallel obligations. The first is the ordinary income tax return. The second is a set of information returns: filings whose job is to disclose who owns what across borders and how money moves between related parties. The IRS enforces this second layer with flat, per-form penalties, which is why a missed information return can cost far more than the tax itself.

If you own a U.S. company with foreign owners, or you are a U.S. person with a stake in a foreign company, plan for both layers from the start. Our business tax return preparation work begins by mapping which of these returns actually apply to your structure.

Who has to file Form 5471?

Form 5471 is aimed at U.S. citizens and residents who serve as officers or directors of a foreign corporation, or who hold shares in one, under the reporting rules of sections 6038 and 6046.[2] The form itself is the Information Return of U.S. Persons With Respect to Certain Foreign Corporations, filed alongside your own return for the tax year.[1]

The penalty for skipping it is unforgiving. It carries a $10,000 penalty for each annual accounting period of each foreign corporation whose information is not furnished, and more can follow if the failure continues after the IRS sends notice.[1] If you hold or help run a company abroad, read our dedicated the Form 5471 filing guide guide before you file.

What is Form 5472 and its $25,000 penalty?

Form 5472 covers a different structure: a U.S. corporation that is 25% foreign-owned, as well as a foreign corporation engaged in a U.S. trade or business.[5] Its purpose is to disclose reportable transactions with foreign or domestic related parties under sections 6038A and 6038C.[4]

The stakes are high. A penalty of $25,000 applies to any reporting corporation that fails to file Form 5472 when it is due.[3] A single foreign-owned LLC that is treated as a corporation for these rules can trigger the filing, which surprises many new owners. Our advisory solutions team can pressure-test your structure before a costly filing gap becomes real.

How do the FBAR and Form 8938 differ?

Money, not just ownership, gets reported. A U.S. person must file an FBAR when foreign financial accounts exceed $10,000 in aggregate value at any point during the calendar year.[6] The FBAR goes to FinCEN and is not attached to your tax return.

Form 8938 is a separate FATCA filing, and meeting the FBAR rule does not remove your obligation to file FinCEN Form 114; the two can both apply to the same accounts.[7] Because the thresholds and definitions differ, many filers complete one and forget the other. We separate the two in our FBAR versus Form 8938 guide.

What is FIRPTA withholding on a real estate sale?

When a foreign owner sells U.S. real estate, the buyer usually has to hold back part of the price and send it to the IRS. Under FIRPTA, the rate of withholding is generally 15% of the amount realized on the sale.[8] The buyer reports and transmits that tax using the Form 8288 series.[9]

This catches many cross-border sellers off guard, because the withholding is the buyer's legal duty, not the seller's, and a buyer who skips it can become personally liable for the amount. For deals involving non-U.S. sellers, see our FIRPTA withholding on real estate guide and our foreign-owned U.S. entity tax services page.

Why do these penalties apply even when no tax is due?

The hardest idea for new owners is that these are information penalties, not tax penalties. The government wants visibility into cross-border ownership and cash flow, so it penalizes the missing form itself. That is why Form 5471 can cost $10,000 and Form 5472 can cost $25,000 for a year in which the business owed no additional tax at all.[1][3]

The filing is the compliance product, and the amounts are set to make skipping it expensive. Treat every information return as mandatory, and confirm which ones apply before the deadline, not after.

How the main cross-border forms fit together

  • You control or help run a foreign corporation: Form 5471, to meet the sections 6038 and 6046 reporting duties.[2]
  • Your U.S. company is 25% foreign-owned, or a foreign corporation does business here: Form 5472.[5]
  • You hold foreign financial accounts over $10,000 in total: the FBAR (FinCEN Form 114), and possibly Form 8938 on top.[6][7]
  • A foreign owner sells U.S. real property: 15% FIRPTA withholding by the buyer, reported on Form 8288.[8][9]

Common cross-border filing mistakes we see

A few patterns repeat. Owners assume that if the business owed no tax, nothing needs to be filed, when the information return is due regardless. New foreign-owned single-member LLCs get treated as invisible, when for Form 5472 they are treated as corporations and must file. Filers report an FBAR but overlook that Form 8938 can apply to the same holdings. And buyers in a real estate deal forget that FIRPTA withholding is their responsibility.

Any one of these can turn a quiet year into a five-figure penalty. Our business tax return preparation and advisory solutions teams review the whole map before filing season, so nothing surfaces as a surprise later.

Frequently asked questions

Does a foreign-owned U.S. LLC have to file Form 5472?

Often yes. A U.S. business that is at least 25% foreign-owned, including a foreign-owned LLC treated as a corporation for these rules, files Form 5472 to report transactions with related parties. Missing it carries a $25,000 penalty, so confirm your filing status early.

What is the penalty for not filing Form 5471?

A $10,000 penalty applies for each annual accounting period of each foreign corporation when the required information is not furnished. Additional penalties can follow if the failure continues after the IRS sends notice. The form satisfies reporting duties under sections 6038 and 6046.

When do I have to file an FBAR?

You file an FBAR when the aggregate value of your foreign financial accounts is more than $10,000 at any time in the calendar year. It goes to FinCEN, separately from your tax return, and Form 8938 may apply to the same accounts under FATCA.

How much FIRPTA tax does a buyer withhold?

Under FIRPTA, a buyer of U.S. real estate from a foreign seller generally withholds 15% of the amount realized and reports it on the Form 8288 series. Reduced withholding is possible in some cases through a withholding certificate.

Do I file both the FBAR and Form 8938?

Possibly. Meeting the FBAR requirement does not remove the obligation to file FinCEN Form 114, and Form 8938 is a separate FATCA filing with its own thresholds. Many taxpayers with foreign accounts end up filing both.

Are these penalties charged even if my business owed no tax?

Yes. Information returns like Form 5471 and Form 5472 are penalized on their own. The $10,000 and $25,000 penalties can apply for a year with no additional tax due, because the filing itself is what the law requires.
