Executive Summary
For most foreign groups establishing a long-term UK operation, a UK subsidiary is usually the preferred structure. It is a separate legal entity, provides stronger liability protection and creates a clearer platform for UK employees, customers, banks and investors.
A UK branch may be suitable where the overseas company is testing the market, wants the UK operation to remain legally integrated with the parent or operates in a sector where a branch structure is commercially or regulatorily appropriate.
The correct choice depends on liability, taxation, public disclosure, VAT, transfer pricing, regulation and the foreign parent’s home-country position.
| Area | UK subsidiary | UK branch |
| Legal status | Separate UK legal entity | Part of the foreign company |
| Parent liability | Usually limited | Parent directly exposed |
| Corporation Tax | Taxed on company profits | Taxed on UK-attributable branch profits |
| Profit extraction | Usually dividends or group charges | Cash transferred to head office |
| Public accounts | UK company accounts filed | Parent accounts may need filing |
| Governance | UK company-law requirements | Managed through branch representatives |
| Best suited to | Long-term UK operations | Market testing or integrated activities |
Introduction
Foreign companies entering the UK normally choose between:
- Incorporating a UK private limited company; or
- Registering a UK establishment, commonly called a branch.
This decision affects:
- Which entity signs contracts;
- Who employs UK staff;
- Whether the parent is directly exposed to claims;
- How UK profits are taxed;
- Which accounts become publicly available;
- How profits are transferred overseas; and
- How easily the UK business can later be sold or restructured.
The cheapest or simplest-looking option at the beginning is not always the most suitable long-term structure.
Regulatory Background
What is a UK subsidiary?
A UK subsidiary is a company incorporated in the United Kingdom and controlled by a foreign parent.
It is a separate legal person and can:
- Sign contracts;
- Employ staff;
- Own assets;
- Open bank accounts;
- Register for UK taxes;
- Borrow money; and
- Sue or be sued.
The company must be registered with Companies House and comply with UK company-law, accounting and filing obligations.
What is a UK branch?
A UK branch is an extension of the overseas company. It is not a separate legal entity.
The foreign parent:
- Signs or assumes responsibility for contracts;
- Owns the branch assets;
- Is responsible for branch liabilities; and
- Remains legally exposed to UK claims.
An overseas company generally needs to register a UK establishment where it has a physical place of business in the UK.
Is a branch the same as a permanent establishment?
No.
A UK establishment is mainly a Companies House concept.
A permanent establishment, or PE, is a Corporation Tax concept. A PE may arise through:
- A fixed place of business, such as an office, shop or factory; or
- A dependent agent who regularly concludes or negotiates contracts for the foreign company.
A company can create a UK taxable presence even if it has not formally registered a branch.
Compliance point: Companies House registration and permanent-establishment analysis should always be considered separately.
Key Rules Explained
1. Liability Protection
UK subsidiary
A subsidiary normally separates the UK business from the foreign parent.
Claims relating to customers, employees, leases or suppliers will generally be made against the UK company.
However, the parent may still be exposed where it:
- Gives a parent-company guarantee;
- Signs contracts directly;
- Assumes responsibility for UK obligations;
- Operates the subsidiary as its agent; or
- Fails to maintain genuine separation between the companies.
UK branch
A branch does not provide legal separation.
The foreign company is directly responsible for:
- Contractual liabilities;
- Employment claims;
- Tax debts;
- Product liability;
- Regulatory breaches; and
- Insolvency risks.
For businesses with significant UK activity, this direct exposure is often a major disadvantage.
2. Corporation Tax
UK subsidiary
A UK subsidiary is generally subject to Corporation Tax on its taxable profits.
Its tax position is calculated using UK accounting and tax rules, with adjustments for matters such as:
- Capital allowances;
- Financing costs;
- Group transactions;
- Losses;
- Transfer pricing; and
- International tax rules.
UK branch
A foreign company is generally subject to UK Corporation Tax on profits attributable to its UK permanent establishment.
The branch must be treated broadly as though it were an independent business dealing with the overseas head office.
This requires an analysis of:
- Functions performed in the UK;
- Assets used;
- Risks controlled;
- Employees and decision-makers;
- Funding; and
- Customer relationships.
A branch cannot simply report whichever profit management chooses to leave in the UK.
3. Transferring Profits Overseas
Subsidiary dividends
A UK subsidiary may distribute profits to its foreign parent by dividend, provided it has sufficient distributable reserves and follows the correct company-law procedures.
The directors should confirm that:
- Profits are legally available for distribution;
- Appropriate accounts support the payment;
- The dividend is properly approved; and
- The company remains solvent.
Branch remittances
A branch can normally transfer cash to its head office without declaring a dividend because both are part of the same legal entity.
However, the branch must still calculate its taxable UK profits and retain appropriate records.
Interest, royalties and management fees
Payments between a UK subsidiary and overseas group companies require careful review.
HMRC may challenge charges where:
- No real service was provided;
- The amount is not commercially supportable;
- The agreement does not match actual conduct;
- Withholding tax has been ignored; or
- The expense is not deductible.
4. Transfer Pricing
A UK subsidiary must price transactions with its parent and other group companies on arm’s-length terms.
Typical transactions include:
- Management services;
- Intercompany loans;
- Software licences;
- Royalties;
- Inventory purchases;
- Employee secondments; and
- Marketing support.
A branch does not legally contract with its own head office. However, internal dealings must still be identified when calculating the branch’s taxable profit.
Common HMRC questions include:
- Who negotiates customer contracts?
- Who controls pricing?
- Who manages commercial risks?
- Who owns customer relationships?
- Where are key decisions made?
- Which entity performs the important functions?
The answers affect both PE risk and the amount of profit taxable in the UK.
5. VAT and Customs
The choice between a subsidiary and branch does not, by itself, determine the VAT position.
The business must consider:
- What goods or services are supplied;
- Where customers are located;
- Whether stock is held in the UK;
- Who acts as importer of record;
- Which entity issues invoices;
- Whether UK staff and technical resources are available; and
- Whether sales are made through online marketplaces.
An overseas business may need to register for UK VAT from its first taxable UK supply, depending on the circumstances.
VAT questions to answer
- Which entity contracts with customers?
- Who owns imported goods?
- Who recovers import VAT?
- Who issues tax invoices?
- Are supplies made between group companies?
- Does the reverse charge apply?
- Could VAT grouping be available?
6. Accounts and Public Disclosure
UK subsidiary
A UK subsidiary must prepare annual statutory accounts and file them with Companies House.
The accounting framework may include:
- FRS 102;
- FRS 101;
- UK-adopted international accounting standards; or
- FRS 105 for qualifying entities.
The subsidiary must also maintain appropriate accounting records and comply with annual confirmation-statement requirements.
UK branch
An overseas company with a registered UK establishment may need to file the foreign parent’s accounts with Companies House.
This can include:
- The parent company’s financial statements;
- Directors’ reports; and
- Auditor’s reports.
As a result, opening a relatively small branch can cause the wider group’s financial information to become publicly available in the UK.
This is one of the most commonly overlooked consequences of choosing a branch.
7. Audit Requirements
A foreign-owned UK subsidiary does not automatically require a statutory audit.
Audit requirements depend on:
- Company and group size;
- Whether the group qualifies for exemption;
- The nature of the business;
- Regulatory status; and
- Shareholder requirements.
A branch may also be affected by the parent company’s home-country audit and filing obligations.
Common audit findings
Common issues in foreign-owned UK businesses include:
- Intercompany balances that do not reconcile;
- Unsupported management fees;
- Missing loan agreements;
- Incorrect foreign-exchange treatment;
- Revenue recorded in the wrong period;
- Weak transfer-pricing documentation;
- Unrecorded payroll liabilities;
- Incorrect VAT recovery;
- Missing inventory;
- Incomplete related-party disclosures; and
- Poor going-concern documentation.
8. FCA and Regulated Businesses
Financial-services businesses must review FCA or PRA requirements before choosing their structure.
The regulator may consider:
- UK presence;
- Local management;
- Systems and controls;
- Client assets;
- Home-country supervision;
- Consumer protection;
- Capital requirements; and
- The ability to supervise the wider group.
Some regulated activities may require a UK-incorporated company, while others may operate through a branch.
The regulatory model should therefore be agreed before incorporation or branch registration.
Which Structure Is Usually Better?
| Business situation | Likely starting point |
| Testing the UK market | Branch |
| Employing a substantial UK team | Subsidiary |
| Signing long-term UK contracts | Subsidiary |
| Holding stock in the UK | Subsidiary |
| High product or customer risk | Subsidiary |
| Seeking UK investment | Subsidiary |
| Planning a future sale | Subsidiary |
| Closely integrated international operations | Branch may be suitable |
| Regulated financial business | Case-specific |
| Avoiding disclosure of parent accounts | Subsidiary often preferable |
Practical Examples
US software group hiring in London
A US software business plans to employ a UK sales and customer-success team.
A subsidiary may be preferable because it provides:
- A clear UK employer;
- A separate contracting entity;
- Better liability protection;
- Easier customer onboarding; and
- A clearer transfer-pricing model.
The group must still consider whether UK staff create a PE for the US parent.
European manufacturer holding UK stock
A European manufacturer imports products, stores them in a UK warehouse and sells to British customers.
A subsidiary is often suitable because it can:
- Own the stock;
- Act as importer;
- Register for VAT;
- Employ local staff; and
- Assume customer and warranty obligations.
Overseas consultancy testing the UK market
A consultancy sends a small team to the UK for a temporary market test.
A branch may be appropriate where:
- The parent accepts direct liability;
- The operation is closely integrated;
- Public filing consequences are acceptable; and
- Branch profit attribution is properly documented.
Common Mistakes
- Assuming a subsidiary automatically prevents PE risk.
- Registering a branch without reviewing public filing obligations.
- Treating cash transfers as the branch’s taxable profit.
- Charging unsupported management fees.
- Ignoring transfer-pricing requirements.
- Assuming VAT registration is not required.
- Incorporating before checking FCA requirements.
- Failing to keep separate UK accounting records.
- Underfunding the UK operation.
- Failing to document why the structure was selected.
Risks and Penalties
An unsuitable or poorly implemented structure can lead to:
- Retrospective Corporation Tax registration;
- Tax interest and penalties;
- Transfer-pricing adjustments;
- VAT assessments;
- PAYE and National Insurance liabilities;
- Companies House penalties;
- Regulatory enforcement;
- Double taxation;
- Audit qualifications;
- Delays in investment or sale processes; and
- Difficulty restructuring the business later.
Problems are often identified during an HMRC enquiry, statutory audit, bank review, FCA application or due-diligence exercise.
Action Plan for Foreign Companies
1. Map the UK activity
Document the proposed customers, contracts, employees, premises, inventory, funding and decision-making.
2. Review permanent-establishment risk
Assess both fixed-place and dependent-agent PE exposure.
3. Compare liability
Identify who will bear customer, employee, property, product and regulatory risks.
4. Model the tax position
Review Corporation Tax, foreign tax credits, losses, withholding taxes, financing and profit repatriation.
5. Review VAT and customs
Confirm VAT registration, invoicing, importer status, customs treatment and import VAT recovery.
6. Check public filing requirements
Determine which subsidiary or parent-company accounts must be filed.
7. Confirm regulatory requirements
Review FCA, PRA and sector-specific obligations.
8. Prepare intercompany agreements
Document services, loans, licences, inventory, secondments and guarantees.
9. Complete UK registrations
Consider Companies House, Corporation Tax, VAT, PAYE, customs and other sector registrations.
10. Create a compliance calendar
Track accounts, tax returns, VAT, payroll, confirmation statements, audits and regulatory filings.
Frequently Asked Questions
What is the main difference between a subsidiary and branch?
A subsidiary is a separate UK company. A branch is part of the overseas parent.
Does a branch protect the parent from liability?
No. The overseas company remains directly responsible for branch liabilities.
Does a UK branch pay Corporation Tax?
The foreign company generally pays UK Corporation Tax on profits attributable to its UK permanent establishment.
Can a subsidiary pay dividends overseas?
Yes, provided sufficient distributable profits exist and the correct procedures are followed.
Can a branch transfer cash to head office?
Yes. This is generally an internal transfer rather than a dividend.
Will the parent company’s accounts be public?
They may need to be filed at Companies House if the foreign company operates through a registered UK branch.
Does a foreign-owned subsidiary need an audit?
Not always. The position depends on company size, group size, regulatory status and available exemptions.
Can a branch later become a subsidiary?
The UK activities can be transferred to a subsidiary, but contracts, employees, assets, VAT and tax consequences must be reviewed.
Does a subsidiary eliminate PE risk for the parent?
No. The parent’s own UK activities must still be analysed.
Conclusion
A UK subsidiary is generally more suitable where the foreign group intends to establish a long-term UK business, employ staff, hold stock, sign contracts or limit legal risk.
A branch may be appropriate where the activity is temporary, closely integrated with the parent or supported by a specific regulatory or tax reason.
The final decision should be based on the complete commercial, legal, tax, VAT, accounting and regulatory position.
