UK Corporate Tax Residence in 2026: Where Is Your Company Really Managed?
The Cogefin judgment is a warning to internationally managed companies: overseas incorporation and local directors do not settle tax residence if strategic control is exercised in the United Kingdom.
Incorporation is a legal fact. Tax residence is also a question of control.
A company may have a registered office in Bermuda, Dubai or Türkiye, a foreign bank account and formally appointed offshore directors. None of those facts, taken alone, proves that the company is managed outside the UK.
For a non-UK-incorporated company, the UK can assert corporation tax residence where its central management and control (CMC) is actually exercised in the UK.
Even where the company is non-UK-resident, it may have a separate UK corporation tax exposure if it carries on business through a UK permanent establishment (PE). These are different tests with different tax consequences.
See HMRC company residence guidance and HMRC permanent establishment guidance .
The practical question is not simply “Where is the company registered?” It is “Who makes its highest-level decisions, where are those decisions genuinely made, and what contemporaneous evidence supports that account?”
This matters to foreign-owned groups, investment holding companies, founders relocating to or from the UK, and UK–Türkiye structures in which boardroom authority and day-to-day activities cross borders.
Cogefin: a Bermuda company treated as UK tax resident
In Cogefin (Bermuda) Ltd & Anor v HMRC [2026] UKFTT 1108 (TC), decided on 30 July 2026, the First-tier Tribunal examined whether a Bermuda-incorporated investment company was centrally managed and controlled in Bermuda or in the UK.
Cogefin had Bermuda-resident professional directors. However, the tribunal found that the directors had, in substance, allowed UK-resident Giuseppe Ciardi to exercise the real decision-making authority over significant company affairs, including major investments and other expenditure.
The tribunal concluded that Cogefin was UK resident for corporation tax purposes during the relevant 1999–2017 periods. Its appeal on corporate residence failed.
The penalty appeal succeeded in part, while Mr Ciardi’s appeal against a personal liability notice was allowed. The decision dealt with principles; the quantum of liability was not determined in that judgment.
Why the existence of offshore directors was not enough
The central issue was not whether the company had properly appointed directors or held formal board meetings outside the UK.
The question was whether those directors genuinely exercised their independent judgment or merely approved decisions already made by another person.
A board can legitimately consider recommendations from shareholders, investment managers and advisers. There is no rule requiring directors to originate every business proposal themselves.
But a distinction must be drawn between considering and approving a recommendation and automatically giving effect to an instruction.
When a board habitually rubber-stamps decisions taken elsewhere, the formal location of its meetings may not reflect the company’s real centre of control.
What Cogefin does not establish
The judgment does not mean that every company with an influential UK shareholder becomes UK tax resident. Shareholder influence, management recommendations and actual usurpation of top-level control must be distinguished on the evidence.
Nor is this a new statutory residence test. The tribunal applied longstanding central management and control principles to a detailed factual record. A First-tier Tribunal decision is also not equivalent to an appellate ruling.

UK tax residence versus UK permanent establishment
These concepts are often conflated. That can create both overstatements of exposure and missed compliance obligations.
| Question | UK corporate residence | UK permanent establishment |
|---|---|---|
| Core test | UK incorporation, subject to exceptions, or central management and control in the UK. | Business carried on through a qualifying fixed place or dependent agent in the UK. |
| Typical tax scope | Generally worldwide profits, subject to reliefs and treaty outcomes. | Generally profits attributable to the UK PE. |
| Evidence | Strategic decisions, actual board authority, investment control, approvals and instructions. | Premises, personnel, commercial activity, contracting practices and habitual conduct. |
| Key mistake | Assuming foreign incorporation guarantees foreign residence. | Assuming no UK subsidiary or formal office means no UK PE. |
This is a simplified overview for general trading structures. UK property income or gains, anti-avoidance rules, VAT, PAYE and other exposures require separate consideration. The applicable double-tax treaty may affect outcomes.
What constitutes central management and control?
CMC concerns the highest level of direction, not simply where routine bookkeeping, technical delivery or administrative work occurs.
For example, a Turkish software company may employ developers in Istanbul, have Turkish customers and maintain its accounting records in Türkiye.
If its principal strategic decisions are nevertheless made by someone permanently based in London, the UK residence position may require closer examination.
Conversely, the presence of one UK-based director does not, by itself, establish that the company is centrally managed and controlled in the UK.
HMRC’s own guidance recognises that management and control may be exercised by the board or by another person who has in fact assumed that authority.

Why a UK-based dealmaker can matter even without an office
Permanent establishment risk is a distinct question. A company may be managed abroad yet conduct sufficient business activity in the UK to establish a taxable presence.
A PE may arise through a fixed place of business, but the dependent-agent route matters too.
For accounting periods beginning on or after 1 January 2026, UK domestic law broadened the relevant agent wording to include a person who habitually plays the principal role leading to contracts routinely concluded without material modification by the company, subject to the statutory conditions.
This can be relevant where a UK-based representative substantially negotiates and drives commercial agreements while the final signature is supplied by personnel in another country.
However, the person’s actual authority, habitual commercial conduct and contractual arrangements require detailed assessment.
Important treaty qualification
Domestic-law wording does not automatically replace a narrower protection in an applicable tax treaty. The relevant treaty, including any Multilateral Instrument (MLI) modifications, must be reviewed before concluding that a UK PE exists or is taxable.

What HMRC’s £16.1 billion figure really says
HMRC’s Large Business Directorate reported £16.1 billion in “tax under consideration” relating to groups with non-UK parents as at 31 March 2026.
This is a measure of potential risk across taxes, not a finding of unpaid corporation tax, an assessed liability, or evidence that all affected businesses have acted improperly.
The figure should therefore not be described as £16.1 billion of proven tax evasion.
It does, however, indicate why group governance, cross-border control and supporting records should be treated as ongoing tax-control issues rather than matters addressed only at incorporation.

Proposed correction rules are not yet an operative blanket obligation
In July 2026, HMRC published draft legislation for a new general requirement to correct specified known tax-return errors and a proposed customer correction notice power.
Its commencement is planned for an appointed future date. Businesses should monitor the proposal, but should not describe it as already in force.

Three UK–Türkiye scenarios worth testing
For internationally mobile owners, the risk often appears when residence, legal incorporation and commercial authority stop aligning.
The following examples are illustrations, not conclusions on any particular business.
A Turkish Ltd. whose major decisions are made in London
A Turkish-incorporated company may remain within Turkish corporate residence rules while also attracting UK scrutiny if its highest-level decisions are genuinely made in London.
Suppose a founder moves to London but retains a Turkish limited company. Turkish employees continue to perform operational work, while the founder makes all major financing, acquisition, investment and strategic contracting decisions from the UK.
That arrangement may raise UK central management and control questions even where the company continues to maintain Turkish offices, bank accounts and accounting records.
Potential dual-residence and treaty questions may therefore arise. A London address or a travelling founder does not decide the matter by itself.
A UK Ltd. run operationally from Istanbul
Consider a British entrepreneur who relocates to Istanbul while retaining a UK limited company.
The company continues invoicing international clients through its UK entity, but its owner now performs significant work and directs the business from Türkiye.
UK incorporation generally makes the company UK resident under domestic law. Managing activities from Türkiye does not simply cancel that status.
However, Turkish corporate-residence, permanent establishment or employment obligations may also arise depending on where management and work take place.
The entrepreneur’s personal Turkish tax residence must also be considered separately from the company’s position.
Both countries’ domestic rules and the applicable double taxation agreement must be evaluated together.
No UK office, but a person habitually drives deals in the UK
A non-UK company may have no UK board or formal branch, yet its UK-based representative consistently negotiates the substantive elements of customer contracts.
For example, the representative identifies customers, negotiates commercial terms and secures agreements while the headquarters routinely signs without material changes.
This calls for a dependent-agent PE review under relevant UK domestic law and the applicable treaty.
The outcome is not automatic. The facts, the nature of the agency relationship and the treaty’s effective provisions remain decisive.
Why the UK–Türkiye tax treaty requires particular care
The UK–Türkiye double taxation agreement is central to assessing cross-border corporate residence and permanent establishment disputes.
Article 4 of the published agreement addresses dual residence for non-individual persons, including a special competent-authority provision where the effective management location and registered office are in different contracting states.
The current effect of the agreement, protocols and any Multilateral Instrument (MLI) modifications must be checked for the accounting periods at issue.
Treaty relief should not be presumed merely because a company possesses a Turkish tax-residence certificate.
Similarly, operating through a company incorporated in Türkiye does not automatically shield business activity from UK taxation.

What an audit-ready management-and-control record looks like
The objective is not to manufacture offshore substance after the fact.
It is to ensure that a company’s documented governance matches its actual governance and to identify weaknesses while corrective options remain available.
- Map reserved decisions. Identify who actually approves financing, large investments, acquisitions, dividends, strategic contracts and material risk decisions.
- Trace the decision process. Keep agendas, briefing papers, alternative proposals, questions, challenge and approval records showing meaningful board deliberation.
- Verify location and authority. Record where relevant decision-makers acted; examine delegated authorities and who can instruct banks, advisers and counterparties.
- Test commercial substance. Check whether directors have sufficient information, capacity and genuine discretion to accept, reject or amend proposals.
- Review people and contracts. Identify UK-based staff or representatives, their habitual roles in negotiations, and whether a fixed-place or dependent-agent PE analysis is required.
- Document both tax positions. Prepare a jurisdiction-specific residence and PE memorandum, a treaty assessment where relevant, and a plan for reporting and remedial action.
Good minutes are evidence—not a substitute for reality. A board that merely rubber-stamps instructions issued elsewhere will not necessarily protect a company’s tax-residence position.
A quick internal screening checklist
- Our incorporation country and actual strategic decision-making location are clearly identified.
- Major decisions can be traced to individuals with genuine authority, not only nominal job titles.
- Director travel, remote-working arrangements and informal approvals are accounted for.
- Contract negotiation and conclusion practices have been reviewed for UK PE exposure.
- Applicable treaty provisions, including effective-date issues, have been checked.
- The company’s position is documented before an HMRC enquiry, not reconstructed from memory during one.
Questions foreign company owners ask
If my company is incorporated outside the UK, is it outside UK corporation tax?
Not necessarily. A non-UK-incorporated company can be UK tax resident if its central management and control is in the UK. It may also be taxable on profits attributable to a UK permanent establishment even if it is not UK resident. Other special taxing rules, including those affecting UK property, can apply.
Does one director or shareholder living in the UK automatically create UK tax residence?
No. Residence is not triggered solely by that person’s address. The critical issue is where the company’s highest-level management and control is genuinely exercised and by whom. The precise factual pattern matters.
Can overseas board meetings solve a central management and control problem?
Only where the board genuinely exercises the relevant decision-making authority. Formal meetings and minutes help evidence real governance; they do not cure a situation in which substantive decisions have already been made elsewhere and directors only approve them mechanically.
Does 183 days in the UK determine where a company is resident?
No. The familiar 183-day discussion concerns aspects of individual taxation and treaty rules; it is not the controlling company-residence test. UK corporate residence and permanent establishment require their own legal analysis.
Can the UK–Türkiye treaty eliminate a dual-residence problem automatically?
No. The specific residence article, any applicable MLI changes and potentially competent-authority procedures must be considered. A treaty analysis can affect the outcome, but one should not assume that a certificate or registered address alone resolves it.
Would a UK PE expose all the company’s global profits to UK tax?
Generally no. A non-UK-resident company’s UK corporation tax exposure through a PE usually relates to profits attributable to that PE. This differs materially from the usual worldwide-profits scope of UK corporate tax residence.
