Form 5471 for BVI or Cayman Companies: UK-Resident US Owners

A UK-resident American who directly owns 10% or more of a BVI or Cayman holding company must generally file Form 5471 every year, and where US persons own more than 50% the company is a controlled foreign corporation. Its passive investment income is usually taxed currently as Subpart F income, and every missing form keeps that year's US return open.

For most owners in this position, the Form 5471 problem is not new. The company was typically incorporated a decade or more ago, often before the owner moved to London, to hold a portfolio, a minority stake or the proceeds of an earlier business sale. It holds a custody account, pays no local tax and files little or nothing locally. Nobody told the US return preparer it existed, or the preparer assumed a company in a zero-tax jurisdiction with no distributions had nothing to report. That assumption is wrong on almost every count. This guide sets out, in the order a US preparer works through it, what the IRS requires for this particular structure, how the income is taxed, how the overlapping account-reporting rules apply, and how years of missed filings are put right.

Does a UK-resident American need to file Form 5471 for a BVI or Cayman company?

Yes, in almost every case. US citizens are taxed and must report on a worldwide basis regardless of residence, so living in the UK changes nothing about the obligation. Form 5471 is required from US persons who fall into one or more of five filer categories in relation to a foreign corporation. A BVI business company or a Cayman exempted company is a foreign corporation for US purposes unless an entity classification election was made on Form 8832 to treat it as disregarded or as a partnership. Without such an election, a company whose shareholders all have limited liability defaults to corporate status, and the 5471 regime applies.

The five categories, simplified, are:

• Category 1 – certain US shareholders of a specified foreign corporation, a category historically tied to the 2017 transition tax.
• Category 2 – US citizens or residents who are officers or directors of a foreign corporation in which a US person acquires a 10% interest or an additional 10%.
• Category 3 – US persons who acquire, dispose of or newly cross the 10% threshold in a foreign corporation, or who become US persons while holding 10%.
• Category 4 – US persons who control the foreign corporation, meaning more than 50% of the vote or value, during its annual accounting period.
• Category 5 – US shareholders (10% by vote or value) of a controlled foreign corporation who own stock on the last day of its year.

A sole American owner of a BVI or Cayman holding company is normally both a Category 4 and a Category 5 filer, which triggers the most extensive set of schedules on the form. In the year of incorporation or acquisition, Category 2 and Category 3 also usually apply. Where a spouse, sibling or parent also holds shares, the constructive ownership rules can push someone over the 10% or 50% line even where their direct stake is smaller. The IRS instructions for Form 5471 set out each category and the schedule matrix in full, and the Form 5471 page on irs.gov carries the current revision.

Is the company a controlled foreign corporation?

A foreign corporation is a CFC if US shareholders, each owning at least 10% by vote or value, together own more than 50% of its vote or value. An American who owns the company outright, or with a US spouse, plainly meets the test. Where the other shareholders are non-US persons, the analysis requires care: a 40% American owner alongside non-US family members may or may not be inside the regime depending on attribution, and the 2025 reconciliation act reshaped the downward attribution rules for certain purposes. The ownership chart, including every family holding, should be documented before a single schedule is completed.

Which Form 5471 schedules apply to a passive holding company?

For a Category 4 and 5 filer, the form is effectively a full set of US-format accounts for the company, prepared under US tax principles and translated into US dollars. The schedules generally required include:

• Schedules A and B – share capital and the identity of US and other shareholders.
• Schedule C – the income statement, which for a holding company is dividends, interest, realised gains and investment expenses.
• Schedule F – the balance sheet, normally drawn from the custody statements because many offshore holding companies have no audited accounts.
• Schedule G – a set of yes/no questions, including questions about PFIC holdings and hybrid arrangements.
• Schedule H – current earnings and profits.
• Schedule I-1 – the information needed for the net CFC tested income (formerly GILTI) computation.
• Schedule J – accumulated earnings and profits, split between previously taxed and untaxed pools.
• Schedule M – transactions between the company and its shareholder, including loans to or from the owner and any personal expenses paid by the company.
• Schedules P, Q and R – previously taxed earnings, CFC income by income group, and distributions.

The hardest part of a catch-up engagement is rarely the form itself; it is reconstructing opening earnings and profits and the tax basis of the portfolio held inside the company. Where the company existed before 2018, its accumulated earnings at the end of 2017 were also exposed to the one-off section 965 transition tax, and that history has to be understood even if the formal catch-up window does not reach back that far.

How is a BVI or Cayman investment company taxed in the US?

This is where the zero-tax jurisdiction works against the American owner. A CFC's income reaches the US shareholder's return in one of three ways: as Subpart F income, as net CFC tested income, or, for anything left over, only when it is distributed.

Subpart F: foreign personal holding company income

Dividends, interest, royalties, rents, annuities and net gains from the sale of property that produces such income are all foreign personal holding company income. For a company whose only business is holding an investment portfolio, that describes almost every dollar it earns. The US shareholder must include their pro rata share of that income on their own Form 1040 for the year the company earns it, whether or not a penny is paid out.

Three features of the rules make the result harsher than owners expect:

• No high-tax exception. Subpart F income can be excluded if it was subject to foreign tax at an effective rate above 90% of the top US corporate rate, currently a threshold of 18.9%. A BVI or Cayman company pays no corporate income tax, so the exception is simply unavailable.
• Loss of preferential rates. Subpart F inclusions are taxed as ordinary income. Qualified dividends and long-term capital gains that would have been taxed at up to 20% if held personally are instead taxed at ordinary rates of up to 37%, with the 3.8% net investment income tax also potentially in point.
• Full-inclusion rule. Where foreign base company income exceeds 70% of the company's gross income, all of its gross income is treated as foreign base company income. A de minimis rule excludes it below the lesser of 5% of gross income or $1 million, which rarely helps a pure holding company.

Net CFC tested income (formerly GILTI)

For tax years of foreign corporations beginning after 31 December 2025, the regime formerly known as GILTI is called net CFC tested income, or NCTI, following the 2025 reconciliation act. Tested income excludes Subpart F income, so for a purely passive company the NCTI inclusion is usually small or nil. It becomes relevant where the company also earns active income that does not fall within Subpart F, and it is computed on Form 8992 using Schedule I-1 data. Individuals do not receive the corporate deduction against NCTI unless they make a section 962 election.

The section 962 election

An individual US shareholder can elect under section 962 to be taxed on Subpart F and NCTI inclusions at corporate rates, as if they held the company through a US corporation. Because the company pays no foreign tax, there is no foreign tax credit to bring across, and a later distribution of those earnings is taxed again as a dividend to the extent it exceeds the tax already paid. For a passive offshore company the election rarely produces a meaningful saving, but in catch-up years it should be modelled rather than dismissed.

Distributions and previously taxed earnings

Earnings already included as Subpart F income or NCTI become previously taxed earnings and profits. When they are later paid out, they are not taxed a second time in the US, although foreign currency gain or loss can arise. Tracking these pools accurately on Schedule P is what prevents double counting years later, when the company is wound up or the portfolio is extracted.

How do the PFIC rules interact with a CFC holding company?

A BVI or Cayman holding company with passive income and passive assets is, on its face, a passive foreign investment company. Many generalist articles stop there and warn of the punitive PFIC regime. The correct position for a controlling owner is more nuanced. Under the CFC/PFIC overlap rule in section 1297(d), a US shareholder of a CFC is generally not treated as holding PFIC stock in that company for the period during which it is a CFC and they are a US shareholder. The Subpart F regime takes priority, and Form 8621 is generally not required for the company itself.

Two complications remain. First, the overlap rule does not reach the company's own investments. If the company holds non-US mutual funds, ETFs or other collective investment vehicles that are PFICs, the US shareholder is treated as an indirect owner of those PFICs, and Forms 8621 may be required for each one. UK-domiciled and Irish-domiciled funds held through the company commonly fall into this trap. Second, a shareholder below the 10% threshold, or who owned the company in years when it was not a CFC, can still be exposed to the PFIC regime for those periods. A clean catch-up file identifies, year by year, which regime applied.

FBAR and Form 8938: reporting the company's accounts

The owner's account reporting does not stop at the shares. Two separate regimes catch the company's bank and custody accounts and the shareholding itself.

FBAR (FinCEN Form 114). A US person has a financial interest in an account owned by a corporation in which they own, directly or indirectly, more than 50% of the vote or value. They must also report any account over which they hold signature authority, which is common where the owner is a director or authorised signatory. Where the aggregate value of all reportable foreign accounts exceeds $10,000 at any point in the year, every account held by the company must be reported. The IRS FBAR guidance explains the financial interest and signature authority tests, and our FBAR penalty calculator illustrates the exposure on missed years.

Form 8938. The shares in the BVI or Cayman company are themselves a specified foreign financial asset. A taxpayer living abroad generally files Form 8938 where specified foreign financial assets exceed $200,000 at year end or $300,000 at any time ($400,000 and $600,000 for married couples filing jointly). Where the interest is reported on Form 5471, Form 8938 simply notes that the asset was reported elsewhere rather than repeating the detail, but its value still counts towards the threshold. The company's underlying accounts are not separately listed on Form 8938 by the shareholder, a frequent point of confusion; they belong on the FBAR.

What are the penalties for not filing Form 5471?

The penalty structure is severe and, importantly, does not depend on whether any tax was due.

• $10,000 per form, per year, under section 6038(b), for each Form 5471 that is late, missing or substantially incomplete.
• Continuation penalties of $10,000 for each 30-day period that the failure continues more than 90 days after IRS notification, up to a maximum of $50,000 per form.
• A reduction in foreign tax credits otherwise available, which compounds for continued failure.
• Open statute of limitations. Under section 6501(c)(8), the assessment period does not begin to run until the required information return is filed. Where the failure is due to reasonable cause, the extension is limited to the items related to the missing form; otherwise the whole return stays open. Either way, a return from a decade ago with no Form 5471 is, in principle, still open today.

Separate penalties apply for missed FBARs, missed Forms 8938 and any unpaid tax on Subpart F inclusions, and accuracy-related penalties can apply to the understatement. For an owner who has never reported a long-held company, the theoretical exposure across all regimes can reach six figures, which is precisely why the route chosen to correct it matters.

How are missed Form 5471 filings cured?

There are three principal routes. Which one is appropriate depends on whether US tax was underpaid, whether the failure was non-wilful, and whether the IRS has already made contact.

Streamlined Foreign Offshore Procedures

For a UK-resident American who meets the non-residency test and whose failure was non-wilful, the Streamlined Foreign Offshore Procedures are usually the strongest option. The taxpayer files the three most recent delinquent or amended US income tax returns, including complete Forms 5471, 8938 and any 8621s, and the six most recent years of FBARs, pays the tax and interest, and certifies non-wilful conduct with a fact-specific narrative. Where the procedures are properly used, no failure-to-file, failure-to-pay, accuracy-related, information return or FBAR penalties are imposed. Because unreported Subpart F income means tax was underpaid, this is often the only cure that closes the exposure without penalty. Our streamlined filing team handles these packages end to end.

Delinquent International Information Return Submission Procedures

Where all income was in fact reported and tax paid, and only the information returns are missing, the Delinquent International Information Return Submission Procedures allow late Forms 5471 to be filed with a reasonable cause statement. This route is rarely right for a passive offshore holding company, because a company earning investment income almost always generated Subpart F income that should have been reported. The procedures are not designed for a taxpayer with underreported tax.

Reasonable cause outside a programme

Late forms can also be filed with a standalone reasonable cause request. The standard is ordinary business care and prudence, and reliance on a professional can support it only where the adviser was given full information. The IRS has historically treated ignorance of the filing requirement as insufficient on its own. This route carries more uncertainty, but can suit a taxpayer who falls outside the streamlined eligibility rules. Where wilfulness is a genuine concern, the IRS Criminal Investigation voluntary disclosure practice, not streamlined, is the relevant framework, and the analysis changes entirely.

Why the three-year window is not the whole story

Streamlined covers three tax years and six FBAR years. It does not prepare returns for earlier years, but the opening balances on the first Form 5471 in the package must still be right: earnings and profits, previously taxed pools and the basis of the portfolio all have to be reconstructed back to incorporation for the three years filed to be accurate. A package built on guessed opening balances is the weak point an examiner will test.

US versus UK treatment of the same company

The UK does not ignore the structure either. A UK-resident individual who has transferred assets to a non-UK company can be charged to UK income tax on that company's income under the transfer of assets abroad rules. The detail, including the motive defence and how the UK and US charges interact for a dual national, is covered in our separate guide to transfer of assets abroad for US-UK dual nationals, and HMRC's transfer of assets abroad manual sets out its interpretation. The table below summarises the parallel position.

Issue	United States (IRS)	United Kingdom (HMRC)
Who is caught	US citizens and residents owning 10%+ of a foreign corporation, regardless of residence	UK-resident individuals who transferred assets to, or can benefit from, a non-UK company
Charging mechanism	Subpart F and NCTI inclusions on Form 1040	Income tax charge on the company's income attributed to the individual
Main information return	Form 5471, plus FBAR and Form 8938	Self Assessment return entries for the attributed income
Character of income	Ordinary income; preferential rates lost	Generally follows the nature of the underlying income
Penalty for non-reporting	$10,000 per form per year, open statute	Offshore penalty regime geared to unpaid tax, with extended time limits for offshore matters
Catch-up route	Streamlined, DIIRSP or reasonable cause	HMRC digital disclosure or unprompted disclosure

Because the two charges arise under different rules and may fall in different years, relief for double taxation needs to be examined year by year, and the US and UK catch-up filings should be prepared together so the figures reconcile. A disclosure to one tax authority with numbers that do not agree with the other is a needless invitation to further questions. Our UK tax team prepares the matching Self Assessment entries.

A worked catch-up: what the engagement involves

Consider an American who moved to London in 2015, owns 100% of a BVI company formed in 2011 that holds a $6 million managed portfolio, and has never filed Form 5471. The company has a bank account and a custody account, and the owner is the sole director. A typical preparation sequence runs as follows:

• Classification and ownership. Confirm no Form 8832 election was ever made, confirm 100% ownership, and document that the company has been a CFC throughout.
• Data collection. Obtain custody statements, bank statements, any local registry filings and records of loans between owner and company, back to incorporation where possible.
• US-basis accounts. Rebuild income, gains and balance sheets in dollars under US tax principles, and compute earnings and profits by year.
• Income classification. Classify each income stream as Subpart F foreign personal holding company income or tested income, and identify any PFIC funds held by the company.
• Returns. Prepare three years of amended or original Forms 1040 with Forms 5471, 8992 where relevant, 8938 and 8621s, plus six years of FBARs reporting both company accounts.
• Certification. Draft the non-wilful narrative for the streamlined certification, specific to the facts.
• Going forward. Put an annual 5471 and FBAR process in place so the company is reported correctly each year, aligned with the UK return.

The cost of compliance is usually the US tax on three years of Subpart F income, plus interest. For many owners that is a fraction of the theoretical penalty exposure, and it is the price of closing a problem that otherwise has no expiry date.

Common errors seen in prior filings

• Reporting the company's dividends on Schedule B as if the owner held the portfolio directly, with no Form 5471 or Subpart F inclusion.
• Filing Form 8621 for the company itself while ignoring the PFIC funds it holds.
• Omitting the company's accounts from the FBAR because they are the company's rather than the owner's.
• Treating the company as disregarded without any evidence that an election was ever filed.
• Choosing the delinquent information return route where Subpart F income was never taxed.
