Introduction: Central Management and Control and Your US Company
Central management and control is the single test that can turn your Delaware corporation into a UK taxpayer. Notably, you never sign a thing. Furthermore, it operates quietly. No form triggers it, no adviser announces it, and no Companies House filing records it. Instead, HMRC applies the test retrospectively, often years later, when an enquiry lands.
Americans who move to London rarely see this coming. Moreover, they assume that a US-incorporated company remains a purely US concern. That assumption costs money. At TaxYork, we regularly meet founders who ran their US entity from a Kensington study for three years. Meanwhile, HMRC had a claim on the whole profit.
Why Central Management and Control Reaches American Owners
Britain uses two residence tests, not one. Additionally, they operate independently. Section 14 of the Corporation Tax Act 2009 makes every UK-incorporated company automatically UK resident, and that rule is irrebuttable. However, the older case law rule sits alongside it and catches foreign companies. Consequently, a company incorporated in Delaware, Wyoming or Nevada becomes UK resident if its central management and control abides here.
The consequence is severe. Specifically, section 5 of the same Act charges a UK resident company to corporation tax on its worldwide profits. Not its UK profits. All of them.
What Changes the Moment You Land in Britain
Nothing visible changes, which is precisely the danger. Nevertheless, the substance shifts immediately. Your board decisions now happen in a British time zone, from a British desk, over British broadband. Therefore, the evidence HMRC would examine begins accumulating from your first week.
Most importantly, the test does not care about your intentions. HMRC states plainly in its International Manual that where central management and control abides is a question of fact. Accordingly, good faith offers no defence.
How the Central Management and Control Test Actually Works
The test locates the highest level of control over a company's business. Furthermore, it looks for real decision-making, not formal authority. HMRC and the tribunals ask a simple question: who genuinely decides, and where do they sit when they decide?
The De Beers Rule and Where Control Abides
The foundation dates to 1906. In De Beers Consolidated Mines Ltd v Howe, Lord Loreburn held that a company resides where its real business is carried on. Furthermore, he located that real business where the central management and control actually abides. That formulation has survived 120 years without statutory replacement.
Importantly, the House of Lords looked past the South African mining operations to the London board that set policy. Similarly, HMRC today looks past your US customers, bank accounts and incorporation certificate. It hunts for the person setting strategy.
Strategic Decisions Versus Daily Management
Central management and control is not the same as running the business day to day. Instead, it concerns matters of general policy and strategy. Examples include approving budgets, authorising borrowing, setting direction and appointing senior people. Consequently, a US operations manager handling customers in Texas does not create UK residence.
The distinction matters enormously for founders. Specifically, you can employ a full US team and keep a US office, yet still fail. The strategic decisions travelled with you. Conversely, you can visit Britain frequently without failing it, provided real decisions stay elsewhere.
Why HMRC Reads Your Emails, Not Your Minutes
Board minutes recording a New York meeting prove very little on their own. Moreover, HMRC knows this. The revenue routinely alleges that an overseas board merely rubber-stamped decisions taken elsewhere. Additionally, modern working habits hand it the evidence.
Every instruction you send by email creates a documentary trail. Likewise, so does every deck you approve on a video call. Therefore, a pattern of London instructions followed by prompt overseas ratification is exactly what defeats a residence claim. In our experience, correspondence decides these cases far more often than minutes do.
The Case Law That Decides Where Central Management and Control Sits
Four decisions shape how central management and control is applied in practice. Furthermore, each one tightened or clarified the line, and together they explain why documentation alone rarely wins.
Wood v Holden and the Usurpation Threshold
Wood v Holden established the taxpayer-friendly boundary. Specifically, the Court of Appeal held that a wholly owned subsidiary does not shift its residence automatically. Acting on the intentions, desires or even instructions of a parent is not enough. Provided the board genuinely exercised its discretion, it held central management and control. Importantly, that board must have been willing to refuse an improper transaction.
Notably, the directors need not conduct detailed analysis. Accepting professional advice is not the same as abdicating. Consequently, a properly constituted overseas board that actually deliberates remains defensible.
Laerstate and the Director Who Never Really Left
Laerstate BV showed the opposite outcome. In that case, a Dutch company was held UK resident. The individual who truly ran it operated from Britain. Notably, that remained true after he resigned as a director. Additionally, the tribunal found that the remaining director lacked the information needed to make real decisions.
The lesson is uncomfortable for owner-managers. Specifically, resigning your directorship changes nothing if you continue deciding. HMRC confirms the point in its guidance on individual directors. What matters is the place from which an individual exercises central management and control. Their personal tax residence is irrelevant.
Development Securities and the Influence Line
The Court of Appeal decided Development Securities in December 2020. It restored the First-tier Tribunal's finding that the Jersey subsidiaries were UK resident. Moreover, the court drew a careful distinction between influencing a subsidiary and controlling it. The Jersey directors had considered the legality of the transactions but never engaged with their merits.
That case moved the line. Therefore, some boards now sit in dangerous territory. They check only that a transaction is lawful, without weighing its commercial merits. Central management and control had, in substance, moved to the UK parent.
What UK Residence Costs an American-Owned Company
The financial consequences arrive in three layers, and the third surprises almost everyone.
Corporation Tax on Worldwide Profits
A UK resident company pays corporation tax on its global profits. For the 2026/27 financial year, the main rate remains 25% on profits above £250,000. Meanwhile, a small profits rate of 19% applies up to £50,000. Furthermore, profits between those figures attract marginal relief, producing an effective marginal rate of 26.5%.
Critically, those thresholds are divided by the number of associated companies. Consequently, an American who owns a US operating company and a UK subsidiary halves both limits. They fall to £25,000 and £125,000.
Failure to Notify Penalties and Open Years
Becoming UK resident creates an obligation to tell HMRC. Specifically, you must register for corporation tax within three months of starting to trade. Furthermore, the CT600 falls due twelve months after the accounting period end. Payment follows nine months and one day later.
Missing all of this compounds badly. Additionally, failure-to-notify penalties under Schedule 41 of the Finance Act 2008 reach 100% of the tax. That rate applies where behaviour was deliberate and concealed. Meanwhile, interest runs from the original due dates, and HMRC's assessing window extends when the omission was careless or deliberate.
The Foreign Tax Credit Mismatch Nobody Budgets For
Here lies the layer that wrecks the arithmetic. A Delaware C corporation remains a US domestic corporation whatever HMRC decides. Therefore, it still files Form 1120 on worldwide income at 21%. In principle, it claims a foreign tax credit for the UK charge on Form 1118.
However, the credit is limited by source. Consequently, the section 904 limitation can strand the UK tax entirely. That happens where the income is US-source, because the services were performed in America. You then pay 25% to Britain and 21% to the United States on the same profit. No relief covers the overlap.
S corporations face a different version of the same problem. Under section 1373, an S corporation is treated as a partnership for foreign tax credit purposes. Accordingly, the UK tax flows through to shareholders. Nevertheless, the identical sourcing limitation applies at the shareholder's level. Moreover, a character mismatch between the two taxes frequently leaves credit unused.
The Treaty Tie-Breaker That Does Not Rescue You
Most commentary assumes the treaty solves dual residence automatically. For companies, it does not.
Article 4(5) and the Competent Authority Route
Suppose central management and control puts your company in Britain while incorporation keeps it in America. You then hold a dual resident company. Individuals enjoy a mechanical tie-breaker of permanent home, centre of vital interests and habitual abode. Companies do not.
Instead, Article 4(5) of the 2001 UK-USA Double Taxation Convention sends the question to the competent authorities. They must endeavour to determine the mode of application by mutual agreement, as the US Treasury text confirms. Furthermore, that process is discretionary, slow and entirely outside your control.
What Happens When the Authorities Do Not Agree
The default outcome is punishing. Specifically, if the competent authorities reach no agreement, the company cannot claim any benefit under the Convention. Only three narrow exceptions survive. They are paragraph 4 of Article 24, Article 25 on non-discrimination and Article 26 itself.
Consequently, reduced withholding on dividends, interest and royalties disappears. Additionally, the business profits article stops protecting you. That combination can cost far more than the underlying corporation tax. Accordingly, proper treaty planning belongs at the structuring stage, not the enquiry stage.
Relief Under Section 18 and Its Limits
British law does offer an override. Section 18 of the Corporation Tax Act 2009 can treat a company as non-UK resident. The relief applies where a double taxation arrangement treats it as resident elsewhere. However, that section only bites once the treaty has actually produced that result. Without a competent authority agreement, the US-UK treaty produces nothing, so section 18 gives your company no shelter at all.
Case Study: A Delaware Corporation Run From Notting Hill
Consider an illustrative client scenario drawn from work we see repeatedly.
The Facts and the Figures
An American founder relocated to London in September 2023, retaining her Delaware C corporation. The software business earned $4.2 million of annual revenue and $1.6 million of profit. She kept two US-resident directors, held quarterly board meetings by video and never registered the company with HMRC. All customers were American.
Where Central Management and Control Landed
HMRC opened an enquiry in 2026 after reviewing her personal return. The evidence was decisive. Every pricing decision, hiring approval and funding negotiation originated from her London flat. Meanwhile, the US directors approved her proposals within hours, without recorded discussion.
Applying Development Securities, the position was indefensible. Central management and control had moved to Britain in September 2023. Therefore, the company had been UK resident for three financial years.
The Cost and the Correction
Three years of worldwide profits at 25% produced roughly £950,000 of UK corporation tax before interest. Meanwhile, the company had already paid US federal tax at 21% on those profits. However, the income was US-source. Consequently, the foreign tax credit relieved almost none of the British charge.
The correction demanded three things. A full disclosure moved penalties from the deliberate band toward the careless range. A competent authority request followed. Finally, a genuine restructuring placed strategic decisions with a properly resourced US board. The lesson is stark. Furthermore, had she taken advice in her first month, the cost would have been a modest restructuring fee.
Protecting Central Management and Control in Practice
Prevention is straightforward once you understand what evidence HMRC values.
Building a Board That Genuinely Decides
Your overseas directors must decide, not ratify. Therefore, give them full board packs in advance, allow genuine deliberation, and record the reasoning rather than the outcome. Additionally, let them occasionally amend or reject a proposal, because a board that has never once said no looks decorative.
The HMRC Examples That Buy You Comfort
HMRC publishes nine worked examples of situations it will not usually review, alongside the limitations on that comfort. Notably, a minority of UK-based directors causes no difficulty where the board meets only outside the UK. Additionally, one or two UK meetings a year are tolerated.
However, example nine removes that comfort in one situation. It applies where most directors habitually perform significant duties in the UK, merely leaving to attend board meetings. Consequently, flying to New York for the quarterly meeting achieves nothing if you run the company from London in between.
Evidence to Keep From Day One
Keep board packs, agendas, the reasoning behind decisions, travel records and evidence that directors were properly informed. Furthermore, HMRC's pandemic-era guidance confirms that the revenue takes a holistic view. A few UK board meetings do not automatically create residence. Meanwhile, remember that the same holistic approach cuts both ways.
Coordinate the corporate position with your personal filings too. Specifically, ownership of a foreign company drives Form 5471 reporting. Meanwhile, foreign account disclosure and your annual US tax return preparation must tell a consistent story. Additionally, any treaty position you adopt requires disclosure on Form 8833.
How TaxYork Can Help
We prepare US and UK tax filings for company owners, investors and executives whose businesses straddle both systems. Furthermore, we assess where central management and control genuinely sits before HMRC does. We use the same evidence the revenue would gather.
Our work covers corporate residence reviews, competent authority requests and corporation tax registration. Additionally, we model foreign tax credits across both regimes and prepare the personal filings alongside. Our team follows technical guidance from bodies such as the ICAEW Tax Faculty. Additionally, we handle catch-up filings where returns are already late. Routes include the IRS Streamlined Filing Compliance Procedures and equivalent UK disclosures.
Above all, we act early. Structuring decisions taken in your first months abroad cost a fraction of the remediation required three years later.
Conclusion
Central management and control determines whether Britain taxes your US company on everything it earns. Importantly, the test turns on facts you create daily. Moreover, the US-UK treaty offers companies no automatic escape, because Article 4(5) requires an agreement that may never come. Consequently, a dual resident company can face 25% British corporation tax alongside 21% US federal tax. Sourcing rules then strand the foreign tax credit.
The remedy is deliberate governance and early advice. Therefore, review where central management and control currently sits if you have moved to Britain. Waiting for an enquiry letter costs far more.
