Do I have to file Form 5471 for a dormant company?

Usually yes. The obligation to file depends on your ownership and your category of filer, not on whether the foreign corporation traded or made a profit. If the corporation meets all eight conditions in Revenue Procedure 92-70 for the whole of its annual accounting period, you may satisfy the obligation with a one page summary return instead of a complete Form 5471. If it fails even one condition, a full information return with the schedules relevant to your filer categories is required.

Does filing dormant company accounts at Companies House mean I do not need to file Form 5471?

No. They are unrelated tests. Companies House dormancy, described in the dormant company accounts guidance on GOV.UK, asks whether the company had significant accounting transactions in the financial year, and disregards only filing fees, late filing penalties and money paid for shares on incorporation. HMRC applies a further and different test for Corporation Tax, which GOV.UK confirms is not the same as the Companies House one. The IRS test in Revenue Procedure 92-70 adds numeric income, expense and gross asset ceilings that UK company law does not use at all.

What exactly is the summary filing procedure for Form 5471?

It is the procedure in Revenue Procedure 92-70 under which you file only page one of Form 5471 for each dormant foreign corporation, with the top margin labelled Filed Pursuant to Rev. Proc. 92-70 for Dormant Foreign Corporations. You complete the filer details, category of filer, percentage of voting stock owned at the corporation's year end, and the corporation's accounting period, name, address, employer identification number if it has one, country of incorporation and date of incorporation. No schedules are prepared. The summary return is attached to your regularly filed income tax return and filed by that return's due date including extensions.

What happens if my dormant company starts trading part way through the year?

The relief is lost for the entire annual accounting period. The dormancy conditions are tested across the whole period and there is no proration, so activity in the eleventh month disqualifies the whole year. A complete Form 5471 with the schedules appropriate to your filer categories is due for that year. Filing the summary return again out of habit leaves an incomplete information return on record and can keep the assessment period open.

Do I need to file Form 5471 when I close or strike off a dormant foreign corporation?

Yes, and the closing year is usually not a summary filing year. Striking a UK company off the register requires remaining assets to be distributed beforehand, and a distribution breaches the no distributions condition in Revenue Procedure 92-70 as well as the condition limiting changes in earnings and profits. A disposition of your shares can also make you a Category 3 filer for that year. The first and last years of a dormant company are structurally the least likely to qualify for the relief.

What is the penalty if I used the summary filing procedure when I was not eligible?

The return is treated as an incomplete Form 5471. Section 6038(b) imposes an initial penalty of $10,000 for each annual accounting period of each foreign corporation, and where the failure continues more than 90 days after the IRS mails notice, a further $10,000 for each 30 day period up to a maximum continuation penalty of $50,000 per failure. Section 6038(c) separately reduces available foreign tax credits by 10 percent, plus 5 percent for each additional three month period. The assessment period for your whole return can also remain open until the correct information is filed.

Form 5471 Dormant Company Relief: Summary Filing

Form 5471 dormant company relief allows a US person to report an inactive foreign corporation on a single page rather than a full information return, using the summary filing procedure set out in Revenue Procedure 92-70. The relief is genuine, but it is narrow. The foreign corporation must satisfy every one of eight conditions throughout its entire annual accounting period, including a ceiling of $5,000 on gross income or gross receipts, a ceiling of $5,000 on expenses, and total asset value that does not exceed $100,000. Fail a single condition and the one page summary return is not a valid filing at all: the position reverts to a complete information return, and section 6038 penalty exposure begins at $10,000 per corporation per year.

That last point is where most of the damage happens in practice. Shelf companies, dormant UK limited companies, holding vehicles parked between deals and post exit corporate shells are exactly the entities whose owners assume that no activity means no filing, or that a one page return will cover them. Both assumptions are wrong more often than they are right. A company that has dropped off HMRC's radar and files dormant company accounts at Companies House can still be a fully reporting foreign corporation for US purposes, and the taxpayer who quietly filed a summary return for six years may have six unprotected years sitting on an open statute of limitations.

What Is the Form 5471 Summary Filing Procedure for Dormant Corporations?

The summary filing procedure is a simplified reporting method under which the filer submits only page one of Form 5471 for each dormant foreign corporation, rather than the full form with its schedules. Revenue Procedure 92-70 states that filers who comply with the procedure satisfy their reporting obligations under sections 6038(a)(1), 6038(a)(4) and 6046(a)(3), and will not be subject to the penalties that attach to a failure to file a timely and complete information return. The procedure has applied to information returns required to be filed, including extensions, on or after 15 September 1992, and it has never been withdrawn.

It is worth being precise about what the relief is and what it is not. It is an information reporting concession only. Section 5 of Revenue Procedure 92-70 is explicit that the relief relates solely to the filer's information reporting obligations and does not affect the filer's liability for tax on income distributed or deemed distributed from a dormant foreign corporation. De minimis amounts of subpart F income earned by a corporation that does qualify as dormant remain taxable to its US shareholders under sections 951 and 952, and must still be reported on the shareholder's own federal income tax return.

There is also a condition attached to using the procedure that most summaries omit. By filing the summary return, the filer undertakes to furnish the full information that a complete Form 5471 would have contained, together with supporting records, within 90 days of a request from the IRS on examination. In other words, the underlying bookkeeping still has to exist. A filer who chose the summary route precisely because nobody was maintaining records for the entity is in a poor position when that request arrives.

Which Corporations Actually Qualify as Dormant Under Revenue Procedure 92-70?

Revenue Procedure 92-70 sets out a conjunctive test. Every condition must be met for the whole of the foreign corporation's annual accounting period, and satisfying seven out of eight is worth exactly as much as satisfying none. The conditions look permissive when read quickly and become considerably tighter when applied to a real balance sheet.

The corporation conducted no business and owned no stock in any other corporation, other than stock in another dormant foreign corporation
No shares of the corporation, other than directors qualifying shares, were sold, exchanged, redeemed or otherwise transferred during the period
No assets of the corporation were sold, exchanged or otherwise transferred, apart from de minimis transfers
The corporation received or accrued no more than $5,000 of gross income or gross receipts
The corporation paid or accrued no more than $5,000 of expenses
The value of the corporation's assets, determined under US generally accepted accounting principles but without reduction for liabilities, did not exceed $100,000
No distributions were made by the corporation
The corporation either had no current or accumulated earnings and profits, or had only de minimis changes in its opening and closing balances of earnings and profits

Two features of that list matter more than the rest. The asset test is measured gross, without netting off liabilities, so a company holding a property worth $400,000 against a $390,000 mortgage is nowhere near dormant even though its net worth is $10,000. And the stock ownership condition rules out the standard structure in which a UK holding company sits above one or more trading subsidiaries. A holding company whose subsidiary trades is not dormant, however quiet the holding company's own bank account may be.

The revenue procedure also makes clear that a corporation which was dormant in a prior year, but which does not meet the conditions in the current year, cannot use the summary filing procedure for the current year. Dormancy is tested annually and afresh. There is no election that carries forward, no grandfathering and no protective effect from having used the procedure correctly in the past.

Why Do the $5,000 and $100,000 Thresholds Catch Out High Net Worth Filers?

These figures were set in 1992 and have never been indexed. For the readership this article is written for, meaning investors, investment bankers, founders between transactions and owners of multiple corporate vehicles, they are extremely low. A dormant company holding sale proceeds, a deposit for a pending acquisition, an intercompany receivable or even a modest securities portfolio will breach the $100,000 asset ceiling immediately. Post exit shells almost never qualify in the year of the exit or in any year in which the proceeds are held, which is precisely the period in which the owner is least inclined to think about foreign corporation reporting.

The expense ceiling is the quieter trap. Accountancy fees, Companies House filing fees, registered office charges, a company secretarial retainer, bank charges and directors insurance are all expenses paid or accrued by the corporation. A UK limited company that is genuinely doing nothing can still run $3,000 to $6,000 a year of professional and administrative cost once a UK accountant, a registered office provider and a bank are involved. Cross $5,000 and the summary filing procedure is unavailable for that year, even though the company has not traded at all.

There is a currency point that is almost entirely absent from the published guidance, and it matters for every UK company. The Revenue Procedure 92-70 thresholds are stated in US dollars. A UK limited company keeps its books in pounds. The $5,000 and $100,000 ceilings therefore have to be tested against a sterling balance sheet translated into dollars, which means an entity's eligibility can flip from one year to the next purely because the exchange rate moved, with no change whatsoever in what the company actually did. A company sitting on GBP 78,000 of cash may be inside the asset ceiling in a weak sterling year and outside it in a strong one. We test this every year rather than assuming last year's conclusion still holds, and we document the translation rate used.

Is a Dormant UK Limited Company Automatically Dormant for the IRS?

No, and this is the single most common misunderstanding we see. Filing dormant company accounts at Companies House and qualifying for the summary filing procedure are two entirely different tests, applied by two different authorities, for two different purposes. A UK company can pass one and fail the other, and it can happen in either direction.

Under UK company law a company is dormant for accounts purposes if it has had no significant accounting transactions during the financial year, a significant accounting transaction being one that the company should enter in its accounting records. Companies House dormant company accounts guidance on GOV.UK confirms that it disregards only a very short list of items when applying that test: fees paid to Companies House for filing, penalties for late filing of accounts, and money paid for shares when the company was incorporated. Where the test is met, a private company limited by shares can deliver dormant company accounts, commonly on form AA02, and the confirmation statement remains due annually regardless.

HMRC then applies a different test again. The GOV.UK guidance on trading and non trading for Corporation Tax states expressly that HMRC's definition of dormant is not the same as the Companies House definition and is not the same as the accounting standards definition. HMRC treats a company as active if it is carrying on a business activity, and that expressly includes earning interest and managing investments. A company must tell HMRC within three months of the start of the accounting period in which it becomes active. So there are already two competing UK dormancy tests in play before the IRS test is added as a third.

A UK company can file dormant company accounts at Companies House and still fail the IRS test, because Companies House looks at transactions while Revenue Procedure 92-70 also imposes a $100,000 gross asset ceiling
A UK company that pays accountancy and registered office fees has made significant accounting transactions and is not dormant at Companies House, yet may still sit inside the IRS $5,000 expense ceiling and be eligible for the summary return
A UK company earning bank interest is active for HMRC Corporation Tax purposes but may be comfortably within the IRS $5,000 gross income ceiling
A UK holding company whose only asset is shares in a trading subsidiary is disqualified from the IRS test outright by the stock ownership condition, whatever its Companies House status
A UK company that has never traded since incorporation can still be disqualified from the IRS test in its first year, because the issue of shares on formation is a transfer of shares

The practical consequence is that a UK accountant confirming a company is dormant is answering a UK company law question. That confirmation is not, and should not be taken to be, a conclusion about eligibility for the summary filing procedure. We treat the two determinations as unrelated and prepare the IRS test independently from the underlying trial balance rather than from the filed dormant accounts.

How Do You Prepare and File the Form 5471 Summary Return?

Mechanically the summary return is straightforward once eligibility has been settled. The filer completes page one of Form 5471 only, and the top margin of that page must be labelled with the wording specified in the revenue procedure: Filed Pursuant to Rev. Proc. 92-70 for Dormant Foreign Corporations. The label is not decorative. It is what tells the IRS that a deliberately abbreviated return is being submitted under an established procedure, rather than an incomplete return being filed by accident.

The filer's name and address, identifying number, category or categories of filer, and the total percentage of the foreign corporation's voting stock owned at the end of its annual accounting period
The filer's tax year covered by the return
The dormant foreign corporation's annual accounting period
The dormant foreign corporation's name and address
The dormant foreign corporation's employer identification number, if it has one
The dormant foreign corporation's country of incorporation and date of incorporation
The prescribed top margin label, entered exactly as the revenue procedure specifies

The summary return is attached to the filer's regularly filed income tax return and is filed by the due date of that return, including extensions. Revenue Procedure 92-70 as issued also directs the filer to send a copy of each summary return to the Internal Revenue Service Center at Philadelphia, together with the filer's other Forms 5471 if there are any. Service centre processing has been reorganised more than once since 1992, so the current Instructions for Form 5471 on IRS.gov should be checked for the filing address in force for the year being filed, rather than relying on the address printed in the 1992 text.

Two administrative points are worth flagging. Schedules are not prepared, but the category of filer box on page one still has to be completed correctly, because the summary return does not change which category or categories the taxpayer falls into under the Instructions for Form 5471 on IRS.gov. And where more than one US person has an interest in the same dormant corporation, the ordinary multiple filer and joint filing rules continue to apply. The summary procedure simplifies the content of the return; it does not simplify the question of who is required to file it.

A Worked Example: A Dormant UK Ltd Held by a US Investment Banker

Consider a fictional but entirely typical filer. Marcus Whitfield is a US citizen living in London and working in investment banking. In 2019 he incorporated Thameside Ventures Ltd, a UK private company limited by shares, intending to use it for a co investment that never happened. He owns 100 percent of the shares. The company has never traded. His UK accountant has filed dormant company accounts at Companies House every year, and the confirmation statement is filed annually without incident. Marcus assumed there was nothing to do for US purposes and filed nothing.

Working through Revenue Procedure 92-70 against the actual figures produces a mixed answer across the years, which is the normal outcome. In the year of incorporation the company issued shares to Marcus, so the condition that no shares were sold, exchanged, redeemed or otherwise transferred fails, and the summary filing procedure is unavailable for that year. Marcus is also a Category 3 filer for that year by reason of acquiring stock that crossed the 10 percent threshold, and a Category 4 and Category 5 filer by reason of control and US shareholder status.

For the following three years the company held GBP 4,000 of cash, earned nothing, and incurred roughly GBP 900 a year of accountancy and registered office fees. Those years sit comfortably inside the $5,000 income ceiling, the $5,000 expense ceiling and the $100,000 asset ceiling, and no shares or assets moved. Those are genuine summary filing years. Then, in the fourth year, Marcus routed GBP 220,000 of proceeds from an unrelated disposal through the company while a purchase was being negotiated. The money sat in the company account for eleven weeks and then left again. That single fact breaches the $100,000 gross asset condition, and the movement of funds is capable of breaching the asset transfer and distribution conditions as well. That year requires a complete Form 5471 with the schedules appropriate to his filer categories.

The compliance answer for Marcus is not one uniform treatment applied to every open year. It is a year by year determination: full returns for the incorporation year and for the year the proceeds passed through, summary returns for the quiet years in between, and a considered decision about how to bring the unfiled years forward. Nothing about the UK dormant accounts filed at Companies House changed any part of that analysis, and nothing in them would have alerted him to it.

What Happens When a Dormant Company Wakes Up Mid Year?

The dormancy test is applied to the whole annual accounting period, not to a part of it. There is no proration and no partial year relief. If a shelf company sits idle for ten months and then signs a contract, receives funding or acquires an asset in November, it was not dormant for that annual accounting period and the summary filing procedure is unavailable for the entire year. A complete Form 5471, with the schedules required for the filer's categories, is due for that year.

This produces a specific and avoidable failure pattern. The company wakes up late in the year, the transaction is handled by corporate counsel and the UK accountant, and the US information return is prepared months later by someone working from a prior year template that used the summary return. The summary return is filed again out of habit. Because it is not a valid filing for that year, the filer has an incomplete Form 5471 on record, and the clock that should have started running on the assessment period for that year never started.

The reverse direction carries a trap of its own. A company that goes quiet after a period of trading does not become eligible for the summary return in the first quiet year simply because the trading has stopped. Accrued expenses, a final distribution, the settlement of intercompany balances or retained sale proceeds will usually breach one condition or another. In our experience the first genuinely clean summary filing year is typically at least one full accounting period after the activity actually ceased, and often later than the client expects.

The year of dissolution deserves the same caution. Striking a UK company off the register requires any remaining assets to be distributed before the application is made, and a distribution breaches the no distributions condition outright. The year in which a dormant UK company is finally wound up or struck off is very rarely a summary filing year, which is the opposite of what most owners assume about a company they are closing precisely because it does nothing.

How Does the Relief Interact With Filer Categories, Subpart F, GILTI and PTEP?

The summary filing procedure does not change who has to file. It changes what that person files. The taxpayer is still a Category 1, 2, 3, 4 or 5 filer, or several of those at once, under the definitions in the Instructions for Form 5471 on IRS.gov, and the correct categories must still be shown on page one. A dormant corporation that is a controlled foreign corporation remains a controlled foreign corporation, and its US shareholder remains a US shareholder, for every other purpose in the code.

On the income side, the relief is silent because it was never designed to reach that far. Revenue Procedure 92-70 satisfies the reporting obligations under sections 6038(a)(1), 6038(a)(4) and 6046(a)(3), and nothing else. It expressly does not affect liability for tax on income distributed or deemed distributed by the corporation. If the corporation has subpart F income, even a small amount of bank interest that keeps it within the $5,000 gross income ceiling, that income is included by the US shareholder under sections 951 and 952 and reported on the shareholder's own return. The same logic applies to a global intangible low taxed income inclusion: a corporation with essentially no tested income will usually produce no inclusion, but the absence of an inclusion is a computational result, not something the summary filing procedure grants.

Previously taxed earnings and profits create a specific problem that almost no published guidance connects to dormancy. Where prior year inclusions have created previously taxed earnings and profits inside the corporation, that balance sits there until it is distributed. The moment it is distributed, two of the eight dormancy conditions are engaged at once: distributions were made, and the earnings and profits balances changed by more than a de minimis amount. A shell held open purely to hold previously taxed earnings and profits is therefore likely to be summary filing eligible for every year in which it does nothing, and disqualified in the exact year the owner finally repatriates the money and stops thinking about the entity. That is the worst possible sequencing, and it is the year most often filed on the old template.

It is equally important to see what the procedure never touched. It does not remove or reduce any other reporting obligation attaching to the same entity or the same bank account. Specified foreign financial asset reporting on Form 8938, foreign bank account reporting on the FinCEN report, transfers of property to the foreign corporation on Form 926, passive foreign investment company reporting, and reporting for any foreign disregarded entity or branch beneath the corporation are each determined under their own rules and their own thresholds. A dormant foreign corporation can generate a full set of adjacent filings while its own Form 5471 is a single page.

What Is the Penalty Exposure if the Summary Filing Was Wrongly Used?

A summary return filed for a year in which the corporation did not meet all eight conditions is not a protected filing. It is an incomplete information return, and it is treated as one. Under section 6038(b) the initial penalty is $10,000 for each annual accounting period of each foreign corporation for which the required information is not filed. Where the failure continues for more than 90 days after the IRS mails notice of it, an additional $10,000 applies for each 30 day period, or fraction of a 30 day period, during which the failure continues after that 90 day window, subject to a maximum continuation penalty of $50,000 for each failure.

There is a second, separate consequence that is frequently more expensive than the fixed penalty. Section 6038(c) reduces the foreign tax credits otherwise available to the filer by 10 percent, with a further 5 percent reduction for each three month period the failure continues beyond the 90 day notice period. For a high earning US person in the UK who relies on foreign tax credits against a substantial UK tax liability, a percentage reduction of the credit pool can dwarf a $10,000 fixed penalty. The Instructions for Form 5471 on IRS.gov set out both mechanisms, and section 7203 criminal penalties remain available in cases of wilful failure.

The statute of limitations point is the one that should drive the decision. An incomplete or unfiled Form 5471 can hold the assessment period open for the taxpayer's entire return, not merely for the items connected to the foreign corporation. A wrongly used summary filing therefore does not simply create a penalty risk on one entity; it can leave the whole year assessable indefinitely. Multiplied across several dormant vehicles and several years, which is the usual pattern for this readership, the exposure compounds quickly and quietly.

Where summary returns have been used for years that did not qualify, the position should be corrected rather than left to run. That means rebuilding the year by year dormancy analysis from the underlying accounts and bank statements, preparing complete Forms 5471 with the correct schedules for the years that failed the test, retaining the valid summary returns for the years that passed, and selecting the appropriate route for bringing delinquent or corrected returns forward with a reasonable cause statement where the facts genuinely support one. The work is document driven and it is done per entity and per year, because that is exactly how Revenue Procedure 92-70 is written and exactly how it will be examined.
