Form 5471 for Americans Who Own or Run a Foreign Company: Who Files and What It Costs to Miss

Americans abroad start businesses like everyone else. Often the local advice is to incorporate: a GmbH in Germany, a Ltd in the U.K., an SA de CV in Mexico. Nobody mentions that the American owner now has one of the most demanding information returns in the U.S. tax system.

That return is Form 5471, Information Return of U.S. Persons With Respect to Certain Foreign Corporations. Here is who files it, and why it matters even when the company owes no U.S. tax.

Who files: the five categories

The Form 5471 instructions, revised December 2025, sort filers into categories based on ownership and role. Simplified:

• Category 1: U.S. shareholders of certain specified foreign corporations described in the instructions, using a 10 percent ownership measure.
• Category 2: U.S. citizens or residents who are officers or directors of a foreign corporation in which a U.S. person has acquired stock meeting the 10 percent ownership requirement, or an additional 10 percent or more.
• Category 3: U.S. persons who acquire stock meeting the 10 percent requirement, among other situations, such as becoming a U.S. person while holding such stock, or disposing of stock so that they fall below 10 percent.
• Category 4: U.S. persons who had control of a foreign corporation, meaning more than 50 percent of the total combined voting power or more than 50 percent of the total value of the stock.
• Category 5: U.S. shareholders of a controlled foreign corporation, meaning a foreign corporation in which U.S. shareholders own more than 50 percent of the vote or value.

An American who owns 100 percent of a foreign company is typically in several categories at once. Each category requires different schedules. The instructions control the details, and they are long.

Notice Category 2. You can have a filing obligation without owning a share, simply by being an officer or director when a U.S. person acquires a 10 percent interest.

The penalties under section 6038

Section 6038(b)(1) imposes a penalty of $10,000 for each annual accounting period for which a required Form 5471 is not furnished on time. If the failure continues for more than 90 days after the IRS mails notice, section 6038(b)(2) adds $10,000 for each 30-day period, or part of one, that the failure continues, with the increase capped at $50,000.

Section 6038(c) adds a second consequence: a reduction of foreign tax credits. Foreign taxes available for credit are reduced by 10 percent, and if the failure continues 90 days or more after notice, by an additional 5 percent for each three-month period, or part of one, that it continues.

The Form 5471 instructions also note separate penalties for failures related to section 6046 reporting on Schedule O, and that criminal penalties under sections 7203, 7206 and 7207 may apply in appropriate cases.

Section 6038(c)(4)(B) addresses reasonable cause by treating the deadline as not earlier than the last day on which reasonable cause existed for the failure. Reasonable cause must be shown.

The open statute problem

Section 6501(c)(8) lists section 6038 among the information reporting provisions that keep a tax year open. If a required Form 5471 is not filed, the time to assess tax for the return does not expire until three years after the information is furnished. If the failure was due to reasonable cause and not willful neglect, the extension applies only to the related items.

For a business owner who never filed Form 5471, that can mean that every year since the company was formed remains open for assessment of tax related to the missing information, and potentially for the entire return if reasonable cause is lacking.

Owning a foreign company changes your income tax too

Form 5471 is an information return, but the U.S. rules on controlled foreign corporations can also pull certain types of the company's income into the American owner's U.S. income each year, even if no dividend is paid. Those rules are complex and change with legislation. The point for this guide is simple: if you own a foreign company, your U.S. return needs someone who understands those rules, and the Form 5471 schedules are where the computations live.

Salary the company pays you for work performed abroad is still foreign earned income that may qualify for the foreign earned income exclusion, but section 911(d)(2)(A) excludes from earned income any part of compensation that represents a distribution of earnings or profits rather than a reasonable allowance for personal services. The salary has to be real compensation, not a disguised dividend.

Form 5471 and your other filings

The company's foreign bank accounts are likely reportable on your FBAR, because under 31 CFR 1010.350(e) a person who owns more than 50 percent of an entity has a financial interest in its accounts. Officers with signature authority may also have FBAR obligations. See signature authority.

If you report the company on a timely Form 5471, you do not detail it again on Form 8938, but you identify it in Part IV of Form 8938. The value still counts toward your Form 8938 threshold. See Form 8938 thresholds.

An example

A U.S. citizen moves to Dublin, forms an Irish private limited company for her consulting practice, and owns all of the shares. The company pays her a salary and keeps some profit in the business. For U.S. purposes, she controls a foreign corporation, so she is at least a Category 4 filer, and because she is a U.S. shareholder owning more than 50 percent, the company is a controlled foreign corporation and she is also a Category 5 filer.

Each year, her U.S. return needs a Form 5471 with the schedules those categories require. Her FBAR includes the company's Irish bank account, because she owns more than 50 percent of the company. Her salary may qualify for the foreign earned income exclusion if it is reasonable compensation for her work. The company's retained profits need to be analyzed under the controlled foreign corporation rules.

None of that changes what she owes Ireland. It changes what she has to tell the United States.

Now suppose she also brings in a U.S. citizen business partner who buys 15 percent of the company. That acquisition can create Category 3 filing for the partner, and Category 2 filing for any U.S. citizen or resident officer or director of the company at the time. One transaction, several new filers. Every American involved in a foreign company should ask the question separately.

Records you will need

Form 5471 asks for the company's income statement and balance sheet, information about shareholders and officers, and transactions between the company and related persons, among other things. Keep the company's annual accounts, share register and bank statements organized by year. Translating local accounts into the form's U.S. dollar schedules is far easier when done annually than when reconstructing five years at once.

When you have missed years

If all income was reported and only the Forms 5471 are missing, the IRS's delinquent international information return procedures call for attaching the missing forms to amended returns with reasonable cause statements. Be aware that for forms other than 3520 and 3520-A, the IRS says penalties may be assessed without considering the attached statement, so be prepared to respond to a notice.

If income was also unreported and the conduct was non-willful, the streamlined procedures generally provide broader penalty protection, including for information return penalties. For Americans abroad, that is the Streamlined Foreign Offshore Procedures.

Either way, the reconstruction work is significant: foreign financial statements must be translated into U.S. tax concepts and dollars for each year. Start early. And if you are about to form a foreign company, let's talk first. It is much cheaper to plan Form 5471 into your life than to retrofit it.
