Form 5471 for US Expats With a Foreign Company: Who Must File, Penalties, and How to Catch Up

Do you even need to file Form 5471?

Form 5471 is an information return attached to your income tax return, or to a partnership or exempt-organization return where that is the one you file. It follows that return's deadline, including extensions. Form 5471 is generally in play for a given year where any one of the following is true:

• You acquired or disposed of foreign-corporation stock in a way that crossed the 10% threshold, or you became a US person while already holding 10%.
• You were a US officer or director of a foreign corporation in which any US person acquired a 10%+ stake.
• You controlled more than 50% of a foreign corporation's vote or value at any point during its accounting period.
• You owned 10%+ of a controlled foreign corporation (CFC), a foreign company more than 50% owned by US shareholders.

These categories overlap and the definitions are technical (constructive-ownership rules can attribute a spouse's or company's shares to you). A wrong call here costs $10,000+. If any of the above is even possibly true, confirm with a cross-border CPA before you file, or before you decide you don't have to. This page is educational, not tax advice.

The five categories of filers, in plain English

The IRS sorts filers into five categories (you can fall into more than one, and each foreign company is a separate Form 5471):

• Category 1: US shareholders of a §965 "specified foreign corporation." This is largely a legacy of the 2017 transition tax and applies to fewer people today.
• Category 2: a US officer or director of a foreign corporation, triggered only in the year a US person acquires 10% or more of its stock (by vote or value); it is a one-time filing for that acquisition, not a standing annual one.
• Category 3: a US person who acquires stock that, added to what they already hold, reaches the 10% threshold; acquires a block that meets the 10% threshold on its own; becomes a US person while meeting it; or disposes of enough stock to drop below it.
• Category 4: a US person who had control of a foreign corporation during its annual accounting period. Control means owning more than 50% of the total combined voting power or total value, directly, indirectly or constructively, at any time during your tax year. There is no minimum holding period.
• Category 5: a US shareholder who owns 10% or more of a foreign corporation that is a CFC at any time during the year, and still owns that stock on the last day the company was a CFC. (The old 30-day minimum-holding rule was repealed by the 2017 tax law.)

What Form 5471 actually reports, and why it can create tax with no payout

For shareholders of a CFC, the form is not just paperwork. Two regimes can make you personally taxable on the company's profits even if it never pays you a dollar:

• Subpart F income: certain passive and mobile income of the CFC is taxed to you currently.
• GILTI (Global Intangible Low-Taxed Income, §951A): a deemed annual inclusion of most of the CFC's active earnings on your personal US return, whether or not anything is distributed. (The One Big Beautiful Bill Act, enacted in 2025, renames GILTI to Net CFC Tested Income (NCTI) for tax years beginning after 2025 and revises the calculation, so confirm the current year's treatment with a professional.)

This is the trap that surprises founders: your Singapore or Hong Kong company can be profitable, retain its cash to reinvest, and still generate a US tax bill on your personal return through GILTI. Planning (elections, foreign-tax-credit coordination, sometimes a check-the-box election) materially changes the outcome, which is why this is rarely a DIY form.

The penalties are severe and applied by default

Under IRC §6038, the penalty for failing to file a timely, complete, and accurate Form 5471 is $10,000 per form, per year. If the information is still not filed more than 90 days after the IRS mails a notice of the failure, an additional $10,000 applies for each 30-day period, or part of one, up to a further $50,000. On top of that, your foreign tax credits can be reduced by 10% (with further reductions for continued non-compliance), and the statute of limitations on your entire return can stay open until the form is filed. Multiply that by several companies and several missed years and the exposure climbs fast, which is exactly why catching up correctly matters. One nuance worth knowing: whether the IRS can assess the §6038 penalty administratively, without going to court, is currently unsettled (the courts have split on it); in practice the IRS still asserts the penalty, so the safe assumption is that it applies.

Related forms you may owe at the same time

Foreign-business owners rarely owe just one form. Depending on the structure:

• Form 8858: for a foreign disregarded entity or branch (the IRS position can reach a foreign sole proprietorship).
• Form 926: to report transfers of property to a foreign corporation.
• Form 5472: a different direction, for a 25%+ foreign-owned US company, or a foreign company doing business in the US. Don't confuse it with 5471.
• FBAR (FinCEN 114) and Form 8938: for the company's and your own foreign financial accounts and assets. See our FBAR guide.
• Form 8621: if you also hold non-US mutual funds, ETFs, or unit trusts, those are usually passive foreign investment companies with their own annual filing. See our Form 8621 and PFIC guide.

The Asia angle: founders in Singapore, Hong Kong, and beyond

This form hits American founders in Asia disproportionately, because incorporating a local Pte Ltd (Singapore) or Limited company (Hong Kong) is the normal way to do business, and a US owner of that company commonly falls into Category 4 or 5, with GILTI exposure. If you set up a company abroad and have not been filing Form 5471, you are not unusual, and you are not without options. See our Singapore and Hong Kong country guides for the local-tax interaction.

Missed years? The catch-up path

Most people who discover this form discover it late. Two different IRS paths can bring delinquent Forms 5471 current, and the right one depends on your facts. The Streamlined Filing Compliance Procedures turn on your conduct having been non-willful. The Delinquent International Information Return Submission Procedures are open to taxpayers who are not under civil examination or criminal investigation and have not been contacted by the IRS about the delinquent returns; you file under the normal instructions and may attach a reasonable-cause statement, but the IRS states that penalties may still be assessed. Where willfulness is a real risk, the Criminal Investigation Voluntary Disclosure Practice is the route, with a tax attorney involved before anything is filed. These are not interchangeable, so this is a review-first situation. If you have also not filed your underlying returns, start with the catch-up guide.

Common questions

Does my small foreign company really trigger a $10,000 form?

Yes. The $10,000-per-form penalty under §6038 is not tied to the company's size or profit. A tiny, dormant, or loss-making foreign corporation still triggers the filing requirement and the penalty for missing it, which is why even small one-person companies abroad need to be on your radar.

I own a Singapore or Hong Kong company. Am I a Form 5471 filer?

It depends on the size of your stake and on whether the company is a controlled foreign corporation. A US person who had control of a foreign company at any time during its accounting period is a Category 4 filer, and a 10%+ owner of a company that is majority US-owned is a Category 5 filer of a controlled foreign corporation. Both must file Form 5471, and both can face GILTI on the company's earnings.

The company keeps its profits and never pays me. Do I still owe US tax?

You can. Under the GILTI rules, US shareholders of a controlled foreign corporation are generally taxed each year on most of the company's active earnings, whether or not those profits are distributed. Elections and foreign tax credits can reduce or eliminate the bill, but they have to be claimed correctly.

I have not filed Form 5471 for several years. What now?

Do not simply start filing the current year and ignore the past. The route depends on your conduct, whether income went unreported, and whether the IRS has already contacted you. Streamlined turns on non-willful conduct. The Delinquent International Information Return procedures require that you are not under examination or investigation and have not been contacted; a reasonable-cause statement is optional and does not guarantee penalty relief. Potentially willful cases go through Criminal Investigation Voluntary Disclosure. Have a cross-border professional confirm which fits before you file anything.

Can general tax software handle Form 5471?

Generally no. Mainstream consumer tax software does not properly support Form 5471, GILTI, or Subpart F, which is a common reason expat entrepreneurs end up with missed or incorrect filings and need specialist help.
