Form 5471 does not tax anything. It reports a foreign corporation you have a stake in, and filing it wrong, or not at all, carries a $10,000 penalty per form per year before the IRS has looked at a single dollar of income.
Whether you have to file at all turns on one question: which of five filer categories you fall into. This guide sets out what the form is, who each category catches, what it reports, and what happens if you miss it.
TL;DR
- Form 5471 is an information return, filed with your income tax return by US persons who own, control or hold office in a foreign corporation. It reports, it does not tax.
- Who files is decided by five categories. Most founders land in Category 4 (control) or Category 5 (a US shareholder of a controlled foreign corporation).
- A US shareholder is a US person owning 10% or more of a foreign corporation's vote or value. A CFC is one that US shareholders own more than 50% of.
- It restates the corporation in US terms, its income, balance sheet and earnings, and for controlling owners it feeds the Subpart F and NCTI tax onto the shareholder's own return.
- It is not Form 5472. 5471 is for US owners of foreign corporations; 5472 is for foreign owners of US corporations. Different direction, different form.
- The penalty is $10,000 per form per year, rising by $10,000 a month after IRS notice to a further $50,000, plus a cut to your foreign tax credits.
- It is filed with your return, on the same due date and extension, and the return's statute of limitations stays open until you file it.
What Form 5471 Is, and Who It Is For
Form 5471, the Information Return of US Persons With Respect to Certain Foreign Corporations, reports a foreign corporation to the IRS. It is filed by the US person connected to that corporation, and attached to their income tax return.
The form carries the corporation's income statement, balance sheet and earnings. Any tax it triggers, through Subpart F or NCTI, the successor to GILTI, is calculated separately and flows onto your own return.
The typical filer is not a large multinational. It is a US person, including a US-resident founder, who holds or controls a company abroad.
| Situation | Form 5471 in play? |
|---|---|
| An Indian founder, now a US resident, who kept their Indian private limited company | Yes, usually as a controlling owner |
| A US startup that opens a foreign subsidiary | Yes, the US parent files |
| A US person who is a director of a foreign company a US group is buying into | Possibly, as an officer or director |
| A foreign owner of a US company | No, that is Form 5472 |
The last row is the distinction that trips people up. Form 5471 runs outbound, a US person reporting a foreign corporation, while Form 5472 runs inbound, a US corporation reporting its foreign owner.
Who Must File: The Five Categories
The filing requirement is built entirely around categories of filer. You do not file because you "have a foreign company", you file because you meet the test for one or more categories, and each carries its own schedules.
| Category | Who it catches |
|---|---|
| Category 1 | US shareholders of a section 965 specified foreign corporation. A narrow, largely transitional group tied to the repatriation rules |
| Category 2 | A US citizen or resident who is an officer or director of a foreign corporation in which a US person has acquired a 10% stake, or an additional 10% |
| Category 3 | A US person who acquires stock crossing the 10% threshold, acquires a further 10%, becomes a US person while holding 10%, or disposes down below 10% |
| Category 4 | A US person who controlled the foreign corporation, more than 50% of vote or value, for an uninterrupted 30 days or more during the year |
| Category 5 | A US shareholder who owns stock in a controlled foreign corporation on the last day of the year it was a CFC |
Two definitions set every threshold in the table above. A US shareholder is a US person owning 10% or more of the vote or value of a foreign corporation.
A controlled foreign corporation is one that US shareholders together own more than 50% of, by vote or value, on any day of the year.
Categories 4 and 5 are where most founders and startups land, because control and CFC status follow directly from majority ownership. A founder who owns their foreign company outright is a Category 4 filer, and usually a Category 5 filer as well, on the one form.
Ownership You Do Not Hold Directly Still Counts
The thresholds are tested using constructive ownership, not just shares in your own name. Stock held by close family, by entities you own, or by partners can be attributed to you.
The attribution reaches through family, partnerships, corporations and trusts. Stock owned by a spouse, child or parent, or by a company you control, is treated as partly yours for the threshold test, which is how a founder with a modest direct holding can still be a controlling owner on paper.
A founder who holds a foreign company through a US LLC, or alongside a spouse, can cross the 10% or 50% line on attributed stock without owning that much directly. The attribution rules decide the category, so they are worth checking before assuming a small direct stake means no filing.
What the Form Reports, and the Tax It Feeds
A complete Form 5471 restates the foreign corporation in US terms. The core is an income statement and balance sheet in US dollars, plus the corporation's earnings and profits, which is the pool that later drives what is taxable to you.
Beyond the core, the schedules you complete depend on your category rather than the form as a whole.
| Schedule | What it covers | Mainly for |
|---|---|---|
| Schedule O | Organization, acquisitions and dispositions of stock | Categories 2 and 3 |
| Schedule J | Accumulated earnings and profits, including previously taxed income | Categories 1, 4 and 5 |
| Schedule Q | The CFC's income sorted into the groups used for NCTI (formerly GILTI) and foreign tax credits | Categories 4 and 5 |
| Schedule I-1 and Schedule P | NCTI inputs and each shareholder's previously taxed earnings | Categories 4 and 5 |
This is why the same form can run to a few pages for one filer and dozens for another. A minority officer filing under Category 2 completes far less than a controlling shareholder of an active CFC.
The form is informational. But for Category 4 and 5 filers it feeds two regimes that can tax the corporation's income to you before any cash comes home:
| Regime | What it reaches |
|---|---|
| Subpart F | Certain mobile income of a CFC, mainly passive income such as interest, dividends and royalties, taxed to the US shareholder in the year it is earned |
| NCTI, formerly GILTI | Most of a CFC's remaining active earnings, taxed currently to the US shareholder and aimed at low-taxed foreign income |
From the 2026 tax year GILTI became Net CFC Tested Income, or NCTI, though the IRS schedules still carry the old label. Whatever the name, the tax reaches low-taxed foreign earnings, not companies in high-tax countries.
Earnings taxed heavily abroad are the ones most likely to escape it, through a high-tax exclusion that survived the change. Lightly taxed earnings are the ones it captures.
Due Date, Extensions and Dormant Companies
Form 5471 has no separate deadline. It is filed with your income tax return, so it inherits that return's due date and any extension.
| Filer | Standard due date | Extended |
|---|---|---|
| Individual | April 15 | October 15 |
| C corporation | 15th day of the 4th month | Generally October 15 |
A foreign corporation that is dormant, holding no significant assets and carrying on no activity, can use the summary filing procedure under Revenue Procedure 92-70.
That files a shortened page-one form rather than the full set, but it is a filing, not an exemption. Skipping it entirely still draws the penalty below.
That penalty is one of the heavier information-return charges, and it applies whether or not any tax was owed.
| Trigger | Penalty |
|---|---|
| Failing to file a required form on time | $10,000 per form, per foreign corporation, per year |
| Still not filed 90 days after IRS notice | A further $10,000 for each 30-day period, up to $50,000 more |
| Foreign tax credits on the same income | Reduced by 10%, with further reductions if the failure continues |
The penalty is charged per corporation. A founder with three unreported foreign entities faces it three times over, $30,000 before any tax is even in question.
It also reaches beyond the foreign corporation. Under section 6501(c)(8), the entire tax return stays open to IRS examination until the missing form is filed and for three years after that, not just the part relating to that corporation.
Penalties can be abated for reasonable cause, but the burden is on the filer to show it, and a late form is safer filed than left unfiled while the statute of limitations sits open.
Mistakes That Cost Filers
- Assuming a small direct stake means no filing. Constructive ownership can attribute family or entity stock to you and push you over a threshold you do not directly cross
- Confusing it with Form 5472. 5471 is a US owner reporting a foreign corporation; a foreign owner of a US company files the other form
- Treating a dormant company as exempt. A dormant foreign corporation still files, just on the shorter summary procedure
- Filing one category and stopping. A controlling shareholder is often a Category 4 and Category 5 filer at once, and the schedules differ
- Reading NCTI, formerly GILTI, backwards. It targets lightly taxed foreign earnings, not companies in high-tax countries

Frequently Asked Questions
Who must file Form 5471?
US persons in one of five categories: shareholders of a section 965 corporation, US officers or directors when a US person acquires 10%, US persons crossing acquisition or disposition thresholds, US persons controlling a foreign corporation, and US shareholders of a CFC. Control and CFC ownership catch most founders.
What are the five categories of filer?
Category 1 covers shareholders of a section 965 specified foreign corporation, Category 2 US officers or directors, Category 3 acquisitions and dispositions of stock, Category 4 control of more than 50%, and Category 5 US shareholders of a controlled foreign corporation. A single filer can fall into several at once.
What is the penalty for not filing Form 5471?
$10,000 per form, per foreign corporation, per year, rising by $10,000 for each 30-day period after IRS notice up to a further $50,000, plus a 10% cut to foreign tax credits. The whole return also stays open to audit until the form is filed.
Is Form 5471 the same as Form 5472?
No. Form 5471 is filed by a US person who owns or controls a foreign corporation. Form 5472 is filed by a US corporation, or a foreign-owned US entity, to report a foreign owner. They run in opposite directions.
This article is general information on Form 5471 and US international tax reporting, and is not legal or tax advice. The category and attribution rules are intricate and facts matter, so confirm your position with a qualified cross-border tax professional before filing or relying on an exemption.
