Introduction: Beneficial Ownership Reporting Narrowed, But Not for Everyone
Beneficial ownership reporting changed more dramatically between 2024 and 2026 than almost any other compliance obligation affecting wealthy Americans abroad. Furthermore, the change ran in the opposite direction to what most advisers expected. In January 2024, roughly 32.5 million American entities faced a brand-new federal filing. By the spring of 2025, that figure had collapsed to fewer than twelve thousand.
Consequently, a great many sophisticated clients now assume the entire beneficial ownership regime has vanished. That assumption is wrong, and it is expensive. The federal rules narrowed, certainly. However, beneficial ownership obligations did not disappear, and the British side of the ledger simultaneously became far more demanding.
Many of our clients own a UK limited company, sit on a board, or hold property through an overseas entity. Consequently, they face beneficial ownership obligations in two jurisdictions at once. Moreover, those obligations run on entirely different clocks, use different definitions, and carry different penalties. At TaxYork, we spend a substantial part of our year untangling exactly this confusion for company owners, fund principals and investors on both sides of the Atlantic.
Why Beneficial Ownership Rules Changed So Suddenly
The Corporate Transparency Act arrived in 2021 as part of a defence spending package. Its purpose was straightforward: strip anonymity from shell companies used to launder money. Accordingly, the Financial Crimes Enforcement Network built a beneficial ownership reporting regime that went live on 1 January 2024.
Litigation followed almost immediately. Subsequently, courts questioned whether Congress had the constitutional authority to compel millions of small domestic businesses to register their owners. Rather than defend that position indefinitely, the Treasury changed course.
On 21 March 2025, the Treasury announced it would remove the requirement entirely for US companies and US persons. The interim final rule took effect on 26 March 2025. Thus, in a single stroke, the regime shrank by more than 99%.
Who This Guide Serves
This guide addresses high-net-worth Americans living in Britain, dual US-UK nationals, accidental Americans, and US business owners with British corporate interests. Specifically, it assumes you have real assets, real structures, and a genuine need for accuracy rather than reassurance. Every beneficial ownership rule cited below reflects the position as at August 2026.
Who Must Still Report Beneficial Ownership to FinCEN in 2026
Only foreign-formed entities registered to do business in the United States must now file. That single sentence determines almost everything. Notably, the deciding factor is where the entity was formed, not who owns it or where they live.
Under the revised rule, a "reporting company" means an entity formed under the law of a foreign country. Additionally, that entity must have registered to do business in a US State or Tribal jurisdiction. Registration happens by filing a document with a secretary of state or similar office. Therefore, your Delaware LLC is out of scope. Your UK limited company might well be in scope.
The Foreign Reporting Company Definition
A UK company becomes a foreign reporting company the moment it registers to transact business in an American state. For instance, a London consultancy that qualifies to do business in New York crosses that line. Similarly, a British trading company that registers in Texas to hold a lease crosses it too.
Registration means a formal filing with a state authority. Consequently, merely selling into the United States, holding a US bank account, or contracting with American customers does not by itself create the obligation. The trigger is the state-level registration document, and nothing less. Therefore beneficial ownership reporting follows registration, never revenue.
The Treasury's own press release confirmed the population fell from approximately 32.5 million entities to roughly 11,667. Consequently, if you are captured, you belong to a very small and very visible group. FinCEN maintains the current rules on its beneficial ownership information page.
The US Person Exemption Explained
Here the rule becomes genuinely counterintuitive, and many advisers still misread it. Foreign reporting companies need not report any beneficial owner who is a US citizen or resident. Furthermore, US persons need not provide their own beneficial ownership information to any foreign reporting company for which they are a beneficial owner.
Imagine a UK company registered in Florida and owned equally by an American in London and a British national in Manchester. Accordingly, the company reports the British owner and omits the American entirely. The wealthier the American, and the larger their stake, the more surprising this outcome feels.
Nevertheless, one obligation survives regardless of citizenship. Every foreign reporting company must identify its company applicant — the individual who filed the registration document, and the person principally responsible for directing that filing. Thus an American who personally signed the state registration paperwork still appears on the report, even though their ownership stake does not.
Deadlines and Penalties That Still Apply
Foreign reporting companies registered before 26 March 2025 faced a deadline of 25 April 2025. Meanwhile, entities registering on or after that date must file within 30 calendar days of receiving notice that registration is effective. Updates and corrections follow the same 30-day rhythm.
Penalties for late beneficial ownership reports remain serious for those still in scope. Civil penalties reach up to $500 for each day a violation continues. Additionally, criminal penalties extend to a fine of up to $10,000 and imprisonment for up to two years. FinCEN's interim final rule questions and answers set out the mechanics in detail.
The Trap for Americans Who Own UK Companies
Most published guidance on this topic addresses American small businesses worried about a Delaware LLC. Very little of it addresses the reader we actually serve: an American in Britain whose principal operating entity is British. That gap creates real risk, because the exposure runs in the opposite direction to the headlines.
Your UK Ltd Registered in a US State
Consider how ordinary this fact pattern is among our clients. A US-born founder builds a UK company, wins American customers, and then registers the company in California or New York to satisfy a client procurement requirement. Consequently, a routine commercial step converts a British company into a federal reporting company overnight.
The founder reads that "US persons are exempt" and concludes nothing is due. However, the exemption protects the individual, not the entity. Therefore the company still files, still names its company applicant, and still reports any non-US beneficial owner holding 25% or more.
Company Applicants Are Easy to Overlook
Company applicant reporting catches people because it sits outside the usual 25% threshold entirely. Specifically, the individual who filed the state registration is reportable whether they own everything or nothing. In practice, that person is frequently the founder, a spouse, or an in-house company secretary.
Moreover, the company applicant requirement applies regardless of citizenship. An American who personally submitted the registration therefore hands over their name, date of birth, address and identifying document. The broad US-person exemption elsewhere in the rule offers no protection here.
What Happens When the Final Rule Lands
The March 2025 rule remains an interim final rule, not a settled permanent one. Importantly, that distinction matters for planning. FinCEN sent a final rule to the Office of Management and Budget on 5 June 2026. Subsequently, in July 2026, its director told a Congressional subcommittee that she was "very optimistic" about issuing it before the year ends.
Consequently, we advise clients to document their current beneficial ownership position now rather than assume permanence. Should the final rule broaden the definition again, entities with contemporaneous records will comply quickly. Those without will scramble. You can track the full FAQ set as the position develops.
Beneficial Ownership Reporting on the British Side
While Washington retreated, London advanced. The Economic Crime and Corporate Transparency Act 2023 imposed the most significant tightening of British corporate transparency in a generation. Consequently, an American who owns a UK company now faces more identity scrutiny in Britain than in the United States.
The PSC Register and Companies House
Britain's equivalent beneficial ownership concept is the person with significant control, or PSC. A PSC owns more than 25% of shares or voting rights. Alternatively, a PSC holds the right to appoint or remove a majority of directors, or otherwise exercises significant influence. Notably, that 25% threshold mirrors the American definition closely, which lulls people into assuming the regimes align. They do not.
From 18 November 2025, companies stopped maintaining their own internal PSC registers. Instead, Companies House became the single authoritative central record. Furthermore, changes must now reach Companies House within 14 days, so the old practice of updating internal records and filing later has ended.
Identity Verification From 18 November 2025
Britain now polices beneficial ownership through identity, not merely through disclosure. Identity verification became a legal requirement for directors and PSCs on 18 November 2025, under the Economic Crime and Corporate Transparency Act 2023. Companies House is implementing it across a twelve-month transition ending in November 2026. In total, an estimated six to seven million individuals must verify.
Deadlines depend on your role, and the distinction trips up overseas owners constantly. If you are a PSC but not a director, you must verify within the first 14 days of your birth month. Alternatively, if you are both a PSC and a director of the same company, your 14-day window begins the day after the company's confirmation statement date.
Living abroad grants no exemption whatsoever. Nevertheless, verification remains practical from overseas, either through GOV.UK One Login or through an authorised corporate service provider. Penalties for failure include uncapped fines and imprisonment for up to two years, as Companies House confirmed at rollout.
The Register of Overseas Entities
A third British beneficial ownership regime catches Americans who hold UK property through non-UK entities. The Register of Overseas Entities came into force on 1 August 2022. Accordingly, an overseas entity cannot buy, sell, transfer, lease, mortgage or charge UK land unless it has registered its beneficial owners.
Registration is not a one-off task. Instead, the entity must review and update the register annually, filing its update statement within 14 days of the anniversary. Moreover, draft legislation before Parliament would require updates within 14 days of any change, not merely once a year. You can review the registration guidance before any transaction completes.
The Reporting That Actually Costs You: US Tax Forms
Here lies the most important point in this entire guide. Even where beneficial ownership reporting to FinCEN has fallen away, your ownership of British entities and accounts still drives substantial US tax filings. Furthermore, those filings carry penalties far heavier than anything in the Corporate Transparency Act.
Clients regularly tell us they are "exempt from beneficial ownership reporting" and therefore relaxed. Unfortunately, they have confused a narrow beneficial ownership registration with the entire architecture of US international tax compliance. The two systems are wholly separate.
Form 5471 and Your UK Company
If you are a US shareholder of a controlled foreign corporation, Form 5471 applies. Your British trading company almost certainly qualifies once American beneficial ownership exceeds 50%. Consequently, the form is due with your return, and the standard penalty for failure starts at $10,000 per form per year.
The rules also tightened for 2026. Specifically, GILTI has been renamed net CFC tested income. Moreover, US shareholders may face inclusions where they own CFC stock on any day of the year, rather than only on the final day. Therefore mid-year share transactions now demand far closer attention than before.
FBAR and Signature Authority
Your foreign accounts trigger a separate report entirely. If the aggregate value of your foreign financial accounts exceeds $10,000 at any point in the year, you must file the FBAR. Importantly, the threshold is aggregate, not per account, so several modest accounts combine.
Signature authority extends the obligation well beyond what you actually own. For example, an American director with signing rights over a UK company's bank accounts reports those accounts personally, despite owning none of the money. Our FBAR and FATCA service exists largely because this point is missed so often.
Form 8938 and FATCA Thresholds
FATCA adds Form 8938 on top. Thresholds are considerably higher for those living abroad, which offers modest relief. A single filer abroad reports where specified foreign financial assets exceed $200,000 at year end or $300,000 at any time during it.
Married couples filing jointly abroad use $400,000 and $600,000 respectively. Nevertheless, sophisticated clients breach these figures routinely, particularly where carried interest, share awards or an investment portfolio sits offshore. The IRS explains the wider framework on its FATCA pages.
Case Study: A London Fund Principal With Three Entities
We recently advised an American principal at a London investment firm, resident in Britain for eleven years and holding a green card. He owned 40% of a UK limited company that advised US institutional investors. Furthermore, he held a 30% stake in a British property entity. He also sat as a director of a third company with no economic interest.
He had read that beneficial ownership rules no longer applied to Americans. Accordingly, he had filed nothing anywhere for two years, and he believed himself fully compliant.
The Position We Found
His UK advisory company had registered to do business in New York in 2023 to service an American client. Therefore it met the foreign reporting company definition precisely. His 40% stake was exempt from reporting because he is a US person. However, his British co-founder held 35% and was fully reportable, and our client had personally signed the New York registration, making him the company applicant.
The property entity, meanwhile, held a Mayfair building and had never filed a Register of Overseas Entities update statement since its initial registration. Furthermore, none of the three companies had completed PSC identity verification, and his birth month deadline had passed in April 2026.
The Exposure in Numbers
The federal position was the least alarming. His company faced up to $500 per day of continuing violation from 25 April 2025. By the time we met, that had already accrued past $180,000 in theoretical exposure.
The US tax position was far worse. He had never filed Form 5471 for either UK company, exposing him to $10,000 per form per year across two entities and multiple years. Additionally, his aggregate foreign accounts exceeded $2.4 million. He also held signature authority over a further $6 million in company accounts. None of it had ever reached an FBAR.
The Outcome
We filed the outstanding beneficial ownership report naming the British co-founder, with our client recorded as company applicant. Simultaneously, we brought all three companies through PSC identity verification using an authorised corporate service provider, and we filed the overdue overseas entity update statement.
For the US tax exposure, we prepared a submission under the Streamlined Foreign Offshore Procedures, covering three years of amended returns and six years of FBARs. Because his failures were genuinely non-wilful and he met the non-residency test, the miscellaneous offshore penalty was nil. Ultimately, roughly $340,000 of theoretical penalty exposure resolved for professional fees and $11,400 of additional tax and interest.
Catching Up If You Have Missed Filings
Timing matters enormously, and one important safety net closed very recently. Consequently, the strategy we would have recommended in June 2026 is no longer the strategy we recommend today.
Streamlined Filing Remains the Principal Route
The Streamlined Filing Compliance Procedures remain open and remain generous for Americans genuinely resident abroad. Qualifying taxpayers file three years of returns and six years of FBARs, certify non-wilfulness, and pay no miscellaneous offshore penalty under the foreign offshore version.
Eligibility turns on non-wilfulness, which is a question of fact rather than a box to tick. Therefore the certification deserves genuine care, because it is signed under penalty of perjury and forms the backbone of the entire submission.
The Delinquent FBAR Route Has Closed
On 1 July 2026, the IRS quietly removed the Delinquent FBAR Submission Procedures from its website without formal announcement. For over a decade, that route let taxpayers file late FBARs penalty-free where all income had been reported and tax paid. Consequently, a predictable and free option has vanished.
No replacement guidance has been issued. Instead, the IRS position is that a late FBAR remains a violation, with penalties assessed on the facts of each case. Many third-party websites still describe the procedure as available, so treat older guidance with real caution.
Correcting Beneficial Ownership Records
Correction is comparatively painless where beneficial ownership records are simply wrong or stale. Foreign reporting companies file corrected reports within 30 days of discovering an inaccuracy. Similarly, Companies House expects PSC changes within 14 days, and overseas entities within 14 days of their update period.
Above all, sequence the work sensibly. We generally regularise the British registers first, because they are cheap and quick, before turning to the US tax submission that carries the real financial weight.
How TaxYork Can Help
We prepare US and UK tax returns for high-net-worth Americans in Britain, and we handle the compliance architecture that surrounds them. Specifically, our work covers Form 5471 for British companies, FBAR and FATCA reporting, beneficial ownership registrations, streamlined catch-up submissions, and the interaction between the two tax systems.
Our clients are company owners, investment bankers, fund principals and investors with genuinely complex affairs. Accordingly, we do not offer generic checklists. We map every entity, every account and every signature authority, then file what is actually required in both countries.
We also coordinate the British side, from PSC identity verification through to overseas entity update statements, so that nothing falls between two sets of advisers. Furthermore, we handle US tax returns for expats and tax treaty optimisation as part of the same engagement.
Conclusion
Beneficial ownership reporting in 2026 rewards precision and punishes assumption. The federal regime narrowed to roughly 11,667 foreign reporting companies, and US persons genuinely fell out of scope as reportable owners. However, the entity obligation survives wherever a foreign company registered to do business in an American state.
Meanwhile, Britain moved firmly in the other direction. Identity verification, a centralised PSC register and an expanding Register of Overseas Entities now demand more from American company owners than Washington does. Therefore, checking only one jurisdiction leaves you exposed in the other.
Above all, remember that beneficial ownership registration and US tax compliance are separate systems. Falling outside the first tells you nothing whatsoever about the second. Form 5471, the FBAR and Form 8938 continue to apply, and they carry the penalties that actually threaten wealth. Professional bodies such as the ICAEW and HMRC publish useful background, yet no general resource can substitute for a proper review of your own structures.
