Do I need to file Form 5471 for a share of freehold company in the UK?

Only if you fall within one of the filing categories in the IRS instructions. A US person who acquires 10% or more of the company's voting power or value files for the year of acquisition, and again for the year of disposal. Annual filing applies only where you hold more than 50%, or where US shareholders together hold more than 50% so that the company is a controlled foreign corporation.

Is owning exactly 50% of a two-flat freehold company control for US purposes?

No. The Form 5471 instructions define control for Category 4 as ownership of more than 50% of the total combined voting power or more than 50% of the total value of the stock. A holding of exactly 50% falls short. It does, however, meet the separate 10% or more requirement, so the year you acquire the share is still a filing year, and a spouse's holding must be considered.

What is the penalty for not filing Form 5471 for a dormant UK company?

The instructions impose a $10,000 penalty for each annual accounting period of each foreign corporation where the required information is not furnished on time. If the failure continues more than 90 days after an IRS notice, a further $10,000 applies for each 30-day period, up to a $50,000 maximum for each failure. The penalty does not depend on the company having any income.

Does a UK flat management company have to file accounts and a corporation tax return?

Every UK limited company must file a confirmation statement and annual accounts with Companies House, even if dormant, although a small dormant company can file dormant accounts. For corporation tax, GOV.UK lists a flat management company among those usually treated as dormant, but HMRC's Property Income Manual confirms that rents such as ground rent remain taxable as property income.

Can I use the dormant foreign corporation procedure for my freehold company?

Possibly, but do not assume so. Rev. Proc. 92-70 allows a summary filing of page 1 of the form only, labelled as filed under that procedure, for a company that meets the definition of dormant in section 3 of the revenue procedure. That definition is not the UK one. A company that owns a freehold or receives ground rent must be checked against each condition every year.

Do I report my freehold company share on Form 8938 as well?

Not in the same year for the same share. Where the holding is reported on a filed Form 5471, you tick item E on that form and record the number of Forms 5471 filed in Part IV of Form 8938. In years with no Form 5471 requirement, the share is a specified foreign financial asset and is reported on Form 8938 if your total assets exceed the applicable threshold.

Form 5471 for a UK Share of Freehold Company: Who Files

Form 5471 is required from a US citizen or green card holder who owns a share in the UK company that holds the freehold of their London building only when that holding crosses one of a few percentage lines: 10% or more of the company's voting power or value when the share is acquired or given up, more than 50% for control, or US shareholders together owning more than 50% so that the company becomes a controlled foreign corporation. In a two-flat conversion or a four-flat mansion block those lines are crossed far more easily than owners expect, because one share per flat means 50% or 25% each. A share with a nominal value of one pound can carry a US information return with a $10,000 penalty attached.

In the returns we prepare for Americans and dual nationals with prime London property, the freehold company is the item most often left off the intake questionnaire. It arrived with the flat, and its only visible activity is an annual email about buildings insurance. This guide sets out how the US filing categories apply and where the arithmetic bites.

What is a share of freehold company, and how does it differ from a residents' management or right-to-manage company?

A share of freehold company is a UK private company that owns the freehold of a building divided into leasehold flats, with each flat owner holding a share in, or membership of, that company. The flat owner is both a leaseholder and a part-owner of the landlord. The GOV.UK leasehold guide at https://www.gov.uk/leasehold-property covers leaseholder rights, service charges, buying the freehold and management disputes. Four arrangements are routinely confused:

Share of freehold company: the company owns the freehold. It is usually limited by shares, with one share per flat, although some are limited by guarantee.
Residents' management company: a company named in the leases to manage and maintain the building. It may or may not also own the freehold.
Right-to-manage company: a company formed to exercise the statutory Right to Manage, which GOV.UK describes at https://www.gov.uk/leasehold-property/right-to-manage-and-management-disputes as letting leaseholders take over certain management responsibilities from the landlord without having to prove bad management. It does not own the freehold and, under the Commonhold and Leasehold Reform Act 2002, is a private company limited by guarantee.
Freehold held in personal names: in very small buildings the flat owners sometimes hold the freehold directly as registered co-owners. There is no company and no foreign corporation question at all.

Before any US form is considered, read the company's Companies House record and its articles: they show the shares or members, the voting rights and the directors.

Why is a small UK private company a foreign corporation for US tax purposes?

A foreign corporation is, for US tax purposes, an entity organised outside the United States that is classified as a corporation under the US entity classification rules. Those rules look at legal form and the liability of the members, not at size, turnover or purpose. A UK private company whose members all have limited liability is generally treated as a corporation by default unless an entity classification election has been made on Form 8832, described at https://www.irs.gov/forms-pubs/about-form-8832 and never, in our experience, filed for a building's freehold company. We put this qualitatively because classification is confirmed against each company's constitution.

There is therefore no exemption for small or purely administrative companies. The filing categories test percentages of voting power and value, not pounds.

When does a share in the freehold company trigger Form 5471?

The current Instructions for Form 5471 (revised December 2025) are published at https://www.irs.gov/instructions/i5471 and define the categories of filer. Category 1 concerns section 965 and is outside this article. Four categories matter for a freehold company:

Category 2: a US citizen or resident who is an officer or director of a foreign corporation in which a US person has acquired stock meeting the 10% stock ownership requirement, or an additional 10% or more in value or voting power.
Category 3: a US person who acquires stock that, alone or added to stock already owned, meets the 10% stock ownership requirement; a person who becomes a US person while meeting it; and a US person who disposes of enough stock to fall below it.
Category 4: a US person who had control of a foreign corporation during its annual accounting period, meaning more than 50% of the total combined voting power of all voting classes, or more than 50% of the total value of all classes of stock.
Category 5: a US shareholder, meaning a US person owning 10% or more of the voting power or value directly, indirectly or constructively, who owned stock in a controlled foreign corporation on the last day in the year on which it was one. A controlled foreign corporation is one whose US shareholders together own more than 50% of the voting power or value on any day of its tax year.

The 10% stock ownership requirement is met by owning 10% or more of the total value of the stock, or 10% or more of the total combined voting power of all classes with voting rights. Categories 2 and 3 are driven by events. Categories 4 and 5 are annual and continue for as long as the condition is met.

Two points are missed constantly. Category 3 includes a person who becomes a US person while already holding 10% or more, so a British flat owner who later obtains a green card has a filing in the year that status begins. Category 3 also covers disposals, so the year the flat is sold and the share passes to the buyer is a filing year. Some older online guides still describe Categories 4 and 5 by reference to a 30-day holding period; that wording is not in the current instructions.

How does the maths work in a two-flat, four-flat or ten-flat building?

Assume the common pattern of one equal voting share per flat. The percentage each flat carries is simply one divided by the number of flats, and the result decides everything:

Two flats: 50% each. The 10% requirement is met, so Category 3 applies in the year of purchase. Exactly 50% is not more than 50%, so one share gives neither control nor, with one US owner, a controlled foreign corporation.
Three flats: one third each. Two US owners hold two thirds, which is more than 50%, so the company is a controlled foreign corporation and both are Category 5 filers every year.
Four flats: 25% each. Two US owners hold exactly 50%, which is not enough. Three hold 75%, and the company becomes a controlled foreign corporation.
Ten flats: exactly 10% each, which meets a test written as 10% or more.
Twelve flats: about 8.3% each, below the line unless one person owns two flats.

The asymmetry is the trap. The lower threshold is 10% or more, so exactly 10% counts. The control and controlled foreign corporation thresholds are more than 50%, so exactly 50% does not.

The position changes when one person owns the whole building. A US owner of both flats in a two-flat house holds 100% of the company and meets both the Category 4 and Category 5a definitions. The item B instructions are specific: such a filer checks only the Category 4 box and leaves Category 5a blank, then completes every item that applies without duplicating information.

Does a spouse's share count towards the thresholds?

Constructive ownership is the set of US rules that treat a person as owning stock legally owned by someone else, including certain family members. The definitions of US shareholder and controlled foreign corporation count stock owned directly, indirectly or constructively, and the instructions refer to Regulations sections 1.958-2, 1.6038-2(c) and 1.6046-1(i). A spouse is within the family attribution rules, but those rules differ between categories, so we state the principle and not a single formula.

The instructions contain two exceptions we rely on regularly. A filer who owns no direct interest, and is caught solely through constructive ownership from another US person, need not file where that person files Form 5471 reporting everything required. And a Category 4 or 5 filer who owns no direct or indirect interest, and is caught solely through constructive ownership from a nonresident alien, need not file. No statement is needed to claim either.

Both exceptions depend on having no direct interest. An American who personally holds one of two shares in a two-flat company, with a husband or wife holding the other, is not in that position. Whether the spouse's share is added for the control test depends on the attribution rule for that category and on the spouse's US status, and we answer that on the documents.

How is a company limited by guarantee with no share capital analysed?

This is the least settled part of the subject, and we say so plainly. The instructions are written entirely in terms of stock, voting power and value. They do not address a company with members and guarantees but no shares, which is the form every right-to-manage company takes.

We do not treat the absence of share capital as an exit. The cautious reading is that a membership carrying a vote is tested by voting power, so one member one vote in a four-flat building produces the same 25% as one share in four. The value limb is harder, because members often have no right to dividends and only a restricted right to surplus on a winding up. We record the articles and the basis of the percentage with the return. This is our working approach, not an IRS-published rule; we have not found one in the instructions.

Can the dormant foreign corporation summary filing procedure be used?

The instructions confirm that Rev. Proc. 92-70 provides a summary filing procedure for a dormant foreign corporation that satisfies the reporting requirements of sections 6038 and 6046. Only page 1 is completed. The top margin is labelled 'Filed Pursuant to Rev. Proc. 92-70 for Dormant Foreign Corporation', the filer's details, items A to C and tax year are entered, and the corporate information is limited to the annual accounting period and items 1a to 1d. The summary return is attached to the income tax return as usual.

The catch is the definition. The instructions say only that a dormant foreign corporation is defined in section 3 of the revenue procedure and do not reproduce its conditions. Those conditions are narrow and are not the UK meaning of dormant. A company that owns a London freehold, receives ground rent, or changes its membership when a flat is sold must be checked against each condition every year. Where a condition is not clearly met, we file the full form.

Which schedules does a tiny non-trading company actually need?

The chart headed Filing Requirements for Categories of Filers decides the schedules. A Category 2 filer completes the identifying information on page 1 and Schedule O, Part I. A Category 3 filer completes the identifying information, Schedules A, B, C and F, and Schedule O, Part II, and attaches a statement of any indebtedness between the company and certain related persons and of the subscribers to its stock. Schedule O reports the organisation of a foreign corporation and acquisitions and dispositions of its stock.

Category 4 and 5a filers face the full set. The instructions give the example of a sole owner who completes all six pages together with separate Schedules E, G-1, H, H-1, I-1, J, M, P, Q and R. For a company with no income most of those contain zeros, but a required schedule with all-zero amounts must still be filed with one or more zero amounts entered. Omitting a schedule because there is nothing to report is the failure mode we see most often on self-prepared returns.

Two presentation rules apply even to a near-empty company. Schedule C, the income statement, is reported in the functional currency, here sterling, under US GAAP. Schedule F, the balance sheet, is reported in US dollars.

How do ground rent and service charge funds appear in the company's accounts?

Two streams of money pass through these companies. HMRC's Property Income Manual at https://www.gov.uk/hmrc-internal-manuals/property-income-manual/pim1075 states that service charges and sinking fund contributions received by a flat management company fall outside the scope of corporation tax, because the company is not beneficially entitled to them. The same page states that rents remain taxable as property income. Ground rent is therefore the company's own income; the service charge fund is not.

Schedules C and F are built from the company's own income statement and balance sheet, so we start from the statutory accounts and reconcile to the separate service charge accounts. In many share of freehold buildings the leases have been extended at a peppercorn ground rent and the company has no income of its own.

Where ground rent or bank interest is received, the US questions multiply. For a controlled foreign corporation, passive income raises the question of a current income inclusion for its US shareholders. For a company that is not one, passive income and assets raise the separate passive foreign investment company question and Form 8621. Both turn on the facts, and we test them each year.

What are the penalties for a missed Form 5471, and how is a late form filed?

The penalties are set out in the instructions and do not scale down for small companies. A $10,000 penalty is imposed for each annual accounting period of each foreign corporation for failure to furnish the information required by section 6038(a). If it is still not filed 90 days after the IRS mails a notice, an additional $10,000 is charged for each 30-day period, or fraction of one, up to a further $50,000 for each failure. A separate $10,000 penalty applies to each failure to report a section 6046 transaction, the acquisition and disposal reporting on Schedule O, with the same continuation penalty and cap. Foreign tax credits can also be reduced by 10%, and criminal penalties may apply.

Late forms are filed under the IRS Delinquent International Information Return Submission Procedures, still published at https://www.irs.gov/individuals/international-taxpayers/delinquent-international-information-return-submission-procedures when we checked. Delinquent returns other than Forms 3520 and 3520-A are attached to an amended income tax return. A reasonable cause statement may be attached to each one, but the IRS states that penalties may be assessed during processing without considering it. The procedure is open to taxpayers who are not under civil examination or criminal investigation and have not already been contacted about the missing returns.

A reasonable cause statement should be factual: how the share was acquired, why it was not recognised as a foreign corporation holding, and when the omission was found. Where missed forms sit alongside unreported income and the conduct was non-wilful, the Streamlined Filing Compliance Procedures are usually the more suitable route.

Is the share reported on Form 8938 or an FBAR?

Stock issued by a non-US company and held directly, outside a financial account, is a specified foreign financial asset under the Instructions for Form 8938 at https://www.irs.gov/instructions/i8938 and so is any interest in a foreign entity. Form 8938 is required only when total specified foreign financial assets exceed the threshold. For a taxpayer living abroad that is more than $200,000 on the last day of the tax year or more than $300,000 at any time for a single filer, and more than $400,000 or $600,000 for a married couple filing jointly. Lower thresholds apply to US residents.

The interaction is a duplicative reporting rule. In a year in which the share is reported on a filed Form 5471, it is not listed again; item E on page 1 of Form 5471 is ticked and the number of Forms 5471 filed is entered in Part IV of Form 8938. In a year in which no category applies, the normal position for a 25% holder after the year of purchase, the share itself goes on Form 8938 if the threshold is exceeded. Its value is seldom the one pound nominal amount, and we record the basis of the estimate.

The FBAR is a different regime. The share is not a bank account, but a US director with authority over the company's bank account has a separate question, which we cover in a dedicated article.

What must the UK company itself file with Companies House and HMRC?

The UK accounts are the source documents for the US schedules. GOV.UK explains at https://www.gov.uk/dormant-company/dormant-for-companies-house that a company is dormant for Companies House if it has had no significant transactions in the financial year. A dormant company must still file its confirmation statement and annual accounts, although a small company can file dormant accounts without an auditor's report.

The corporation tax meaning is separate. GOV.UK states at https://www.gov.uk/dormant-company/dormant-for-corporation-tax that a flat management company is among those usually dormant for corporation tax, and that HMRC may write to say it will treat the company as dormant, so that no Company Tax Return is required. That sits alongside the manual's position that rents remain taxable, so a company receiving ground rent should not assume it has nothing to report. A company that lets its filings lapse risks being struck off, a serious problem when it owns the freehold.

What does this look like in practice? A worked scenario

This is an illustration with invented facts, not a client case. Caroline is a US citizen in investment banking in London. In 2025 she buys a flat in a four-flat Kensington building whose freehold company has four issued one pound shares, one per flat. She receives one share and becomes a director. The other three owners are UK nationals with no US status.

For 2025 she has acquired 25%, which meets the 10% requirement, so she is a Category 3 filer. As a US citizen director of a foreign corporation in which a US person acquired a qualifying holding, Category 2 is in point too. She checks both boxes, completes the Category 3 schedules with Schedule O, and attaches the form to her Form 1040 by its due date including extensions.

For 2026 nothing changes. She has no control and the company is not a controlled foreign corporation, so no Form 5471 is due. The share is considered for Form 8938.

In 2027 a second flat is sold to a US citizen, who has a Category 3 filing. Caroline, as a US director, has a Category 2 filing for that acquisition unless a specific exception applies. US shareholders now hold exactly 50%, so the company is still not a controlled foreign corporation.

In 2028 a third flat is bought by a green card holder. US shareholders hold 75%, the company is a controlled foreign corporation, and all three are Category 5a filers for that and every later year in which the position continues. None holds more than 50%, so none is a Category 4 filer. One may file a joint Form 5471 for all three. Nothing about the building has changed.

What should you check before your next US return?

Identify the vehicle: is there a company, and is it limited by shares or by guarantee?
Count the shares or votes and work out your percentage, including any second flat.
Establish which other flat owners are US citizens, green card holders or US residents.
Test 10% or more for the year you acquired the share, became a US person, or sold.
Test more than 50% for control, and in aggregate among US shareholders, remembering that exactly 50% fails both.
Consider your spouse's holding and status under the constructive ownership rules.
Collect the statutory and service charge accounts and identify any ground rent or interest.
Check the Rev. Proc. 92-70 conditions before using the summary procedure.
Where no Form 5471 is due, decide whether the share belongs on Form 8938.
If past years were missed, assemble the facts for a reasonable cause statement before filing piecemeal.

A freehold share is a small asset with a disproportionate compliance footprint. We prepare Form 5471 for these holdings as part of the US return, working from the UK company's accounts, and bring missed years into line. The IRS overview of the form is at https://www.irs.gov/forms-pubs/about-form-5471 for the current revisions.
