Form 5471: Who Files, and How to Avoid the $10,000 Penalty
If you own a piece of a company outside the United States, an Indian Pvt Ltd, a startup, a family business, the IRS may expect Form 5471 with your return. Miss it, and the penalty starts at $10,000 before any tax is even owed.

Form 5471 is an information return, not a tax bill. It tells the IRS about your ownership in a foreign corporation and the company's finances. The trap is that the penalty for not filing does not depend on whether you owe any tax. It applies just for the form being late or missing.
What Form 5471 is for
The official name is the Information Return of U.S. Persons With Respect to Certain Foreign Corporations. It is attached to your personal or business tax return and reports who owns the foreign company, its income statement and balance sheet, and items the U.S. may tax currently, such as Subpart F income and GILTI.
Do you have to file? Start with ownership
The form uses a set of filing categories, and which one applies drives how much of the form you complete. The most common categories for founders and investors are:
Category 5
A U.S. shareholder, owning 10% or more, of a controlled foreign corporation (a CFC, meaning U.S. shareholders together own more than 50%). This is the typical case for a U.S. founder who owns most of an Indian company.
Category 4
A U.S. person who had control, generally more than 50%, of a foreign corporation for at least 30 days during the year.
Categories 1, 2, and 3
Cover U.S. officers and directors, certain acquisitions and dispositions of stock, and shareholders of specified foreign corporations. You can fall into more than one category at once.
The 10% test looks at vote or value, and ownership can be direct, indirect, or constructive, meaning shares held by close family or related entities can be attributed to you. This is where do-it-yourself filers most often get the answer wrong.
A U.S. citizen or green-card holder who owns 10% or more of an Indian private limited company is usually a Category 5 filer, and the company is often a CFC. That pulls in GILTI and Subpart F, and may require elections to manage the U.S. tax on undistributed earnings.
The deadline
Form 5471 is filed with your income tax return, including extensions. It is not a separate filing and has no separate due date. If you extend your 1040 or your business return, the 5471 rides along with it.
The penalties
- $10,000 per form, per year, for failing to file a complete and accurate Form 5471 by the due date.
- If you do not file within 90 days of an IRS notice, an additional $10,000 for each 30-day period, capped at $50,000 per form.
- A possible reduction of your foreign tax credits, which can raise your actual tax bill on top of the flat penalties.
Because the form is often required for several years of the same company, a missed filing can multiply quickly across open years.
GILTI and Subpart F, briefly
Owning a CFC can mean paying U.S. tax on the company's earnings even if nothing was paid out to you. Subpart F captures certain passive and easily moved income. GILTI, global intangible low-taxed income, sweeps in much of the remaining active earnings of a CFC. There are elections and credits that soften the result, but they have to be made correctly and on time.
If you missed prior-year filings
There are reasonable-cause and penalty-relief paths, and for non-willful cases the Streamlined Filing Compliance Procedures can cover late 5471s along with the rest of the return. Do not paper-file old forms without a plan. The category, the elections, and the income inclusions all need to line up.
Form 5471 rarely travels alone. It usually comes with FBAR, FATCA, and treaty questions. We handle them together through our cross-border tax practice. See also the FBAR filing guide and the U.S.-India tax treaty guide.

Form 5471 questions we hear most
I own shares in an Indian Pvt Ltd. Do I file Form 5471?
Quite possibly. A U.S. person who owns 10% or more of a foreign corporation, including an Indian private limited company, is usually a Category 4 or Category 5 filer. The exact category depends on your ownership percentage and whether the company is a controlled foreign corporation.
What is the penalty for not filing?
The base penalty is $10,000 per form, per year. If you do not file within 90 days of an IRS notice, an additional $10,000 applies for each 30-day period, up to $50,000, and your foreign tax credits can be reduced.
When is Form 5471 due?
It is attached to your income tax return and is due when that return is due, including extensions. It is not filed separately.
What are GILTI and Subpart F?
They are rules that can tax you on the foreign company's earnings even if no money was distributed. GILTI applies to global intangible low-taxed income, and Subpart F captures certain passive and mobile income of a controlled foreign corporation.
