The Form 5471 late filing penalty is $10,000 for each form, for each year it is late or incomplete, under section 6038(b) of the Internal Revenue Code. If the IRS sends a notice and the form is still missing after 90 days, a further $10,000 is added for every 30 days, up to $50,000 more. The penalty applies even where the company made no profit and no US tax is due.
Form 5471 is the information return for US persons with interests in foreign corporations. Americans who own a UK limited company, or a UAE free zone company, often learn about it years after they should have started filing. By then the arithmetic looks alarming. However, the outcome is rarely the headline figure, provided you act before the IRS does. This guide explains how the Form 5471 late filing penalty is calculated, the other consequences, and the routes to relief.
How the Form 5471 late filing penalty is calculated
The penalty is fixed in the statute and is not adjusted for inflation. The IRS describes the form and its filing categories on its About Form 5471 page.
| Consequence | Amount | Source |
|---|---|---|
| Initial penalty | $10,000 per form, per annual accounting period | Section 6038(b)(1) |
| Continuation penalty | $10,000 per 30 days after the 90-day notice period, up to $50,000 | Section 6038(b)(2) |
| Maximum per form per year | $60,000 | Section 6038(b) |
| Foreign tax credit reduction | 10% of the credits linked to the company, rising if the failure continues | Section 6038(c) |
| Assessment period | Stays open until three years after the form is filed | Section 6501(c)(8) |
Per form and per year
The penalty is charged for each foreign corporation and each year. An owner of one UK company who missed five years faces five initial penalties, or $50,000, before any continuation penalty. Two companies would double that. You can read the statute in the text of section 6038.
Incomplete forms count as late
A form that is filed on time but is substantially incomplete is treated as not filed. Therefore, a Form 5471 without its required schedules, or with estimated figures in place of accounts, can attract the same $10,000.
The open assessment period
Under section 6501(c)(8), the time limit for the IRS to assess tax does not start to run until the required form is filed. Where the failure has no reasonable cause, the whole return stays open, not only the items linked to the company. Consequently, a missing Form 5471 can keep an otherwise old tax year exposed indefinitely.
Can the IRS actually assess the penalty?
This question went to court. In Farhy v. Commissioner, decided in April 2023, the US Tax Court held that the IRS had no statutory authority to assess section 6038(b) penalties and had to sue to collect them. In May 2024, the Court of Appeals for the D.C. Circuit reversed that decision and confirmed that the IRS can assess the penalty. Later in 2024, in Mukhi v. Commissioner, the Tax Court said it would keep to its original view in cases appealable to other circuits.
Why this matters for Americans abroad
Section 7482(b)(1) of the Internal Revenue Code generally sends a Tax Court appeal to the D.C. Circuit where the taxpayer has no legal residence in the United States. As a result, the D.C. Circuit ruling is the one that normally governs an American living in the UK or UAE. You should not plan on the Farhy argument, and the position should be checked against current case law before any penalty is contested.
Routes to relief from the Form 5471 late filing penalty
Which route fits depends on whether you also have unreported income and whether the IRS has already contacted you.
Reasonable cause
Section 6038 provides that no penalty applies where the failure was due to reasonable cause. You make the case in a signed statement that sets out the facts: what you knew, whom you relied on, and what you did when you found out. Reliance on a qualified adviser who was given full information is a recognised ground. Ignorance of the law alone is weaker, although the facts of a small owner-managed company abroad are often sympathetic.
Delinquent International Information Return Submission Procedures
If you reported all your income and owe no tax, you can file the missing forms with a reasonable cause statement under the IRS Delinquent International Information Return Submission Procedures. The IRS states that penalties may still be assessed under this route. Therefore, the quality of the statement matters.
Streamlined Filing Compliance Procedures
If the missing forms come with unreported income, and the failure was non-wilful, the Streamlined Filing Compliance Procedures are usually the better route. A taxpayer who qualifies for the foreign version files three years of returns with the information returns attached and pays no penalty on them. Our IRS streamlined filing page explains the conditions.
First-time abatement
First-time abatement is an administrative waiver for taxpayers with a clean record. For individuals, it is generally not available on its own for international information return penalties. Our guide to the IRS penalty abatement waiver explains where it does apply.
Who has to file in the first place
Many penalties arise because the owner did not realise a filing category applied. A US person who owns more than 50% of a foreign corporation files as a Category 4 filer. A US shareholder of a controlled foreign corporation files as a Category 5 filer. Acquiring 10% or more triggers Category 3. Our guide to the Form 5471 categories of filers sets out each one, and our guide to the Form 5471 filing requirements lists the schedules.
Dormant companies still count
A UK company that is dormant for Companies House purposes still needs a Form 5471 if you are in a filing category. However, Revenue Procedure 92-70 allows a summary filing for a dormant foreign corporation that meets its conditions, which reduces the work considerably.
An illustrative case
Consider an illustrative US citizen in Bristol who has owned 100% of a UK consultancy company since 2021. The figures are illustrative. He filed Form 1040 each year and reported his salary and dividends, but never filed Form 5471. In 2026 he has five missing forms and a theoretical exposure of $50,000 in initial penalties. He owes no extra tax, because the income was reported. His adviser prepares the five forms and a reasonable cause statement explaining that his previous preparer never raised the form. He files before any IRS notice arrives. The exposure is real, but a prompt, well-documented voluntary filing gives him the strongest available position.

Frequently Asked Questions
How much is the penalty for filing Form 5471 late?
The penalty is $10,000 for each Form 5471 for each annual accounting period under section 6038(b) of the Internal Revenue Code. If the form is still not filed 90 days after an IRS notice, a further $10,000 applies for each 30-day period, up to an additional $50,000, giving a maximum of $60,000 per form per year.
Does the penalty apply if my company made no profit?
Yes. Form 5471 is an information return, and the section 6038(b) penalty does not depend on any tax being due. A loss-making or dormant foreign corporation still requires the form if you fall within a filing category.
Can the Form 5471 penalty be waived?
Yes, where the failure was due to reasonable cause. You submit a signed statement of facts with the late forms. Taxpayers with unreported income and non-wilful conduct may instead use the Streamlined Filing Compliance Procedures, under which qualifying non-residents pay no penalty.
Did the Farhy case remove the Form 5471 penalty?
No. The US Tax Court ruled in Farhy v. Commissioner in April 2023 that the IRS could not assess the penalty, but the Court of Appeals for the D.C. Circuit reversed that ruling in May 2024. Appeals by taxpayers with no US residence generally go to the D.C. Circuit, so the penalty remains assessable for most Americans abroad.
Do I need Form 5471 for a dormant UK limited company?
Yes, if you are in a filing category, for example because you own more than 50% of the shares. Revenue Procedure 92-70 permits a summary filing for a dormant foreign corporation that meets its conditions, but the form cannot simply be omitted.
Does a UAE free zone company require Form 5471?
Yes, if it is treated as a corporation for US tax purposes and you meet a filing category. A UAE free zone company owned by a US citizen is a foreign corporation, and the same $10,000 penalty in section 6038(b) applies to a late or missing form.
