Branch, Subsidiary or New Company? How to Structure an International Expansion
Why the first question is not "which company type?" — it is "what will the business actually do there?"
Opening Thesis
Expanding into a new country does not begin with a company registration form. It begins with a business question: what will actually happen there?
Will there be employees? Contracts with local customers? Invoicing? Inventory? Premises? Assets? Regulated activity? Borrowing? Investors? Is this a local market or a regional hub? The answers to these questions should determine the structure — not the other way round.
The legal structure should follow the business. Not the other way round.
Key Takeaways
- A branch and a subsidiary are fundamentally different legal structures. A branch is generally an extension or registered presence of an existing foreign legal entity rather than a separate company. A subsidiary is ordinarily a separately incorporated legal entity owned by a parent. The precise treatment of each depends upon local law. The choice between them has material legal, tax, regulatory and commercial consequences.
- A branch does not necessarily mean less tax complexity. A branch may create a taxable presence — a permanent establishment — in the country where it operates, depending upon domestic law and the applicable treaty. The parent company may then be subject to tax in that country on profits attributable to the branch. This is not necessarily simpler than operating through a subsidiary.
- A subsidiary can provide greater legal separation — but that separation should not be overstated. A subsidiary is ordinarily a separate legal person from its parent. But legal separation does not automatically mean complete commercial separation. Guarantees, cross-defaults, intercompany financing, regulatory obligations and actual conduct can all affect the practical extent of separation.
- Permanent establishment can potentially arise without a formally registered branch. The absence of a formal branch registration does not automatically mean the absence of a permanent establishment. Depending upon domestic law and the applicable treaty, a fixed place of business, a dependent agent or other facts may be relevant to a PE analysis.
- A subsidiary does not automatically constitute a permanent establishment of its parent. A subsidiary is a separate legal entity. Ownership of a subsidiary does not, by itself, make the subsidiary a permanent establishment of the parent. However, the facts of how the parent and subsidiary interact can be relevant to a PE analysis under applicable domestic law and treaty provisions.
- Tax should not determine the structure in isolation. Tax is an important consideration in structure selection. A structure that cannot obtain the banking and payment infrastructure required for its intended operating model may be commercially unworkable. Commercial objective, operating model and legal structure should be determined first. Tax analysis should follow.
- A subsidiary creates intercompany relationships. When a parent and subsidiary transact with each other — for management services, intellectual property, financing, staff or other matters — those transactions are related-party transactions. They may require appropriate agreements and pricing under applicable transfer-pricing rules. This is a consequence of legal separation, not a problem to be avoided.
- A representative office can be useful for limited market-presence activities where local law permits it. Some jurisdictions permit representative offices or analogous limited-presence establishments for market research, liaison, promotion and relationship development. The precise activities permitted and the applicable restrictions vary by jurisdiction. A representative office is not a substitute for a full operating presence.
- Banking and licensing should be considered before the entity is created. Banking feasibility and regulatory licensing requirements should be assessed during structure design, not after incorporation. A structure that cannot obtain the necessary banking relationships or regulatory approvals may be commercially unworkable regardless of its legal validity.
- The structure should anticipate tomorrow's business — not merely today's registration. The structure appropriate to test a market may not be the structure appropriate to build a regional business. The cheapest structure to establish is not necessarily the cheapest or easiest structure to operate. Structure selection should consider the likely trajectory of the business, not only its immediate requirements.
Structures & Legal Framework
Start With the Operating Model
Before selecting a legal structure, a business entering a new market should define precisely what will happen there. The answers to the following questions should drive the structural decision:
- Will there be employees in the new country?
- Will the business enter contracts with local customers?
- Will it invoice locally?
- Will it hold inventory, premises or assets?
- Is the activity regulated?
- Will the operation require local borrowing or external finance?
- Will there be investors?
- Is this a local market operation or a regional hub?
- How significant is the operation expected to become?
Commercial objective → operating model → legal structure → tax & regulatory analysis → implementation.
Not: company type → incorporation → work out how to use it afterwards.
What Is a Branch?
A branch is generally an extension or registered presence of an existing foreign legal entity rather than a separate subsidiary company. The precise treatment depends on local law. In many legal systems, a branch does not constitute a separate legal person from the foreign enterprise, although its precise legal status, registration requirements, powers and obligations depend upon the law of the jurisdiction concerned.
A branch may contract, employ and operate in the new country, but the legal obligations are generally those of the parent. Local registration, licensing and compliance requirements may still apply.
What Is a Subsidiary?
A subsidiary is ordinarily a separately incorporated legal entity owned wholly or partly by a parent company, subject to local law. It is a distinct legal person from its parent.
A subsidiary can ordinarily contract, employ, own assets, incur liabilities, bank and invoice in its own name, subject to local law. The parent owns the subsidiary. It is not ordinarily the same legal person as the subsidiary.
The subsidiary has its own shareholders (the parent, and potentially others), its own directors, its own accounts and its own legal obligations. It is subject to the corporate law of the jurisdiction in which it is incorporated.
The choice between branch and subsidiary is not merely administrative. It has material consequences for legal liability, tax, regulation, banking, employment, transfer pricing and future flexibility.
Legal Separation and Liability
One important reason for choosing a subsidiary over a branch is the potential for greater legal separation between the parent and the overseas operation. A subsidiary is ordinarily a separate legal person. Its liabilities are, in principle, its own. The parent is not automatically liable for the subsidiary's obligations merely by virtue of ownership.
A branch, by contrast, is generally not a separate legal person from the parent. The parent's legal exposure to the branch's activities may therefore be more direct, depending upon local law.
Limited liability is important. It is not a force field around the rest of the group.
The Limits of Legal Separation
Legal separation through a subsidiary does not automatically mean complete commercial separation. A number of factors can affect the practical extent of separation:
- Parent guarantees of subsidiary obligations
- Cross-default provisions in financing arrangements
- Security granted by the parent over subsidiary assets or vice versa
- Intercompany financing arrangements
- Regulatory obligations that extend to the group
- Contractual commitments made by the parent on behalf of the subsidiary
- The actual conduct of the parent in relation to the subsidiary's affairs
The degree of legal separation available through a subsidiary depends upon local law, the specific facts and the terms of any relevant agreements. It should not be assumed to be absolute.
Branches, Tax and Permanent Establishment
A branch may create a permanent establishment (PE) in the country where it operates, depending upon domestic law and the applicable double taxation agreement. A PE can result in the parent company being subject to tax in that country on profits attributable to the branch.
The concept of a permanent establishment is defined in domestic law and, where applicable, in the relevant bilateral tax treaty. The OECD Model Tax Convention provides an internationally influential framework for PE analysis, but domestic law and the specific wording of the applicable treaty remain decisive in an individual case.
A fixed-place PE can arise where a business has a fixed place of business through which the business of the enterprise is wholly or partly carried on. Under the OECD Model framework and treaties containing comparable provisions, a dependent-agent PE can potentially arise where the relevant treaty conditions are satisfied, including certain circumstances involving the habitual conclusion of contracts or the principal role leading to their conclusion. The precise test depends upon domestic law and the wording of the applicable bilateral treaty.
Legal registration and taxable presence are related. They are not the same question.
Permanent Establishment Without a Registered Branch
A business can potentially create a permanent establishment in a country without formally registering a branch there. The absence of a branch registration does not automatically mean the absence of a PE. Depending upon domestic law and the applicable treaty, relevant facts can include: a fixed place of business, an office, construction activity, or a dependent-agent arrangement.
No branch registration does not automatically mean no permanent establishment.
Remote Work and Market Entry
The growth of remote working has made PE analysis more relevant to market entry decisions. A senior employee working from a home office in another country may, depending upon the facts, domestic law and the applicable treaty, be relevant to a PE analysis for the employer.
The OECD's 2025 update to the Model Tax Convention introduced guidance addressing when cross-border remote work — including work performed from an individual's home office — can create taxable presence for an enterprise. The OECD Model and Commentary provide an international treaty framework and interpretative guidance; domestic law and the applicable bilateral treaty remain decisive in an individual case.
Remote work can be relevant to a PE analysis. It does not create a universal automatic rule.
Consider a hypothetical: a company based in Country A sends a senior executive to work from their home in Country B for an extended period, performing functions that are central to the company's business. Depending upon the facts, domestic law and the applicable treaty, this arrangement may be relevant to a PE analysis. The facts matter. The applicable rules must be checked.
This is one reason why remote working arrangements for internationally mobile employees should be considered as part of market entry planning, not treated as a purely HR matter.
When a Subsidiary Can Affect the Parent's PE Analysis
A subsidiary is a separate legal entity. Ownership of a subsidiary does not, by itself, make the subsidiary a permanent establishment of the parent. This is an important principle — but it is not absolute.
The facts of how the parent and subsidiary interact can be relevant to a PE analysis. Depending upon domestic law and the applicable treaty, relevant considerations can include: whether the parent uses premises at the subsidiary's location as its own fixed place of business; whether personnel of the subsidiary habitually act for the parent in a way that could constitute a dependent-agent PE; whether the contracts and actual conduct are consistent; and whether the subsidiary's activities are genuinely its own or are effectively those of the parent.
Ownership of a subsidiary does not, by itself, make the subsidiary a PE of the parent.
The analysis depends upon the facts, domestic law and the applicable treaty. Where the factual relationship raises questions concerning the parent's use of premises, agency activity or the functions performed on the parent's behalf, specialist advice should be obtained.
The Wider Branch vs Subsidiary Decision
The branch vs subsidiary decision involves multiple dimensions. The following factors are relevant — but they are indicators, not a universal decision rule:
- Control: A branch may offer more direct parent control. A subsidiary has its own governance structure.
- Regulation: Some regulated activities require a locally incorporated entity. Others can be conducted through a branch. Local law determines this.
- Customers: Some customers or counterparties prefer to contract with a locally incorporated entity.
- Banking: Banking availability and requirements can differ between branches and subsidiaries.
- Employment: Employment law, payroll and HR obligations may differ depending on the structure.
- Tax: Branch and subsidiary tax treatment differs. Neither is universally more favourable.
- Transfer Pricing: A subsidiary creates related-party transactions requiring appropriate pricing.
- Financing: A subsidiary may be able to raise local finance in its own name.
- Investors: A subsidiary can provide a separate equity vehicle into which external investors may invest. A branch does not have separate share capital in the same way.
- Exit: A subsidiary can be sold. A branch cannot be sold in the same way.
Commercial & Tax Considerations
Subsidiaries as Separate Commercial Units
Beyond the legal and tax analysis, a subsidiary can serve a commercial purpose as a distinct business unit. Where the overseas operation is expected to become a material business in its own right, a subsidiary can provide:
- Clearer regional profitability — the subsidiary's accounts reflect the performance of the overseas operation separately from the parent
- Local management — the subsidiary can have its own management team with appropriate authority
- Investor participation — external investors can take a stake in the subsidiary without acquiring an interest in the parent
- Employee incentives — equity or profit-sharing arrangements can be structured at the subsidiary level
- Local financing — the subsidiary may be able to raise finance from local banks or investors in its own name
- Future disposal — the subsidiary can be sold as a going concern
A separate subsidiary can create a clearer commercial unit where the overseas operation is expected to become a material business in its own right.
These are potential advantages, not universal outcomes. The commercial case for a subsidiary depends upon the nature and scale of the overseas operation.
Intercompany Relationships and Transfer Pricing
When a parent and subsidiary transact with each other, those transactions are related-party transactions. They may require appropriate agreements and pricing under applicable transfer-pricing rules. Common intercompany transactions include:
- Management services provided by the parent to the subsidiary
- Intellectual property licensed by the parent to the subsidiary
- Financing provided by the parent to the subsidiary
- Staff seconded between parent and subsidiary
- Technology or systems provided by the parent
- Administrative support
The OECD Transfer Pricing Guidelines provide an internationally influential framework for applying the arm's-length principle to transactions between associated enterprises, including analysis of economically significant functions, assets and risks. The applicable legal requirements depend upon domestic law and the particular facts.
Subsidiary: greater legal separation + more intercompany relationships. Branch: legal continuity + potential PE profit-attribution complexity.
Neither structure eliminates tax complexity. They create different types of complexity.
Repatriating Profits
How profits are moved from an overseas operation back to the parent depends upon the structure chosen and the applicable rules. The mechanisms available, and their tax treatment, differ between branches and subsidiaries.
For a subsidiary, possible mechanisms for returning value to the parent can include: dividends, interest on intercompany loans, royalties or licence fees for intellectual property, management or service charges, and repayment of intercompany financing. Each mechanism has its own legal, tax and transfer-pricing implications. Withholding taxes may apply to dividends, interest and royalties depending upon domestic law and the applicable treaty. The appropriate mechanism depends upon the specific facts and applicable rules.
For a branch, profits are generally attributed to the parent directly rather than distributed as a dividend. The tax treatment of branch profits depends upon domestic law and the applicable treaty. Some jurisdictions impose a branch profits tax or equivalent charge on profits remitted or deemed remitted to the head office.
The mechanisms for returning value from an overseas operation to the parent differ between branches and subsidiaries and require case-specific analysis.
Tax Residence Still Matters
Establishing a subsidiary in Country B does not eliminate the need to consider the residence rules of other relevant jurisdictions. Depending upon Country A's domestic corporate-residence rules, management exercised there may cause Country A also to treat the company as resident or otherwise create additional tax consequences.
Legal presence and tax residence should not be confused.
Banking Before Incorporation
Banking feasibility should be considered during structure design, not after incorporation. The banking infrastructure available to a branch and to a subsidiary may differ. Relevant questions include:
- Which financial institutions serve the relevant sector and jurisdiction?
- Does the institution accept foreign-owned entities?
- What currencies and international payment capabilities are required?
- Are merchant services or trade finance required?
- What are the KYC and source-of-funds requirements?
- What are the local operational banking requirements?
If the structure cannot obtain the banking or payment infrastructure required by its intended operating model, that may materially affect its commercial viability. Banking feasibility should be assessed alongside legal and tax analysis, not after it.
Banking feasibility should be considered during structure design.
Regulation Can Determine the Structure
In some sectors and jurisdictions, the applicable regulatory framework determines the legal structure. A business cannot always choose freely between a branch and a subsidiary. Depending upon the country and sector, law or regulation may prescribe: the required legal form, licensing requirements, minimum capital, local management or director requirements, ownership restrictions, premises requirements, and reporting obligations.
Sectors where regulatory requirements can determine structure include: financial services, insurance, payments, investment management, healthcare, education, telecommunications and professional services. This list is illustrative, not exhaustive.
A tax-efficient entity that cannot lawfully conduct the intended activity is not a viable structure.
Representative Offices
Some jurisdictions permit representative offices or analogous limited-presence establishments. Where available, a representative office may be suitable for: market research, liaison activities, promotion and marketing, and relationship development.
The precise activities permitted through a representative office, and the applicable restrictions, vary by jurisdiction. Depending upon local law, a representative office may be restricted from entering commercial contracts, generating revenue or conducting full commercial operations in its own name. It is a market-exploration tool, not a substitute for a full operating presence.
Representative office: explore the market. Not necessarily: conduct full commercial operations.
A representative office may be appropriate as an initial step in a new market, allowing a business to assess commercial opportunities before committing to a full branch or subsidiary structure. The transition from a representative office to a full operating presence requires careful planning, as the applicable rules and tax treatment may change.
Not all jurisdictions offer a representative office concept. Where available, the applicable rules should be verified from current local sources.
Practical Application
Regional Companies and Group Architecture
As a business expands internationally, a regional holding or management company may become commercially justified. A regional structure may serve purposes including: consolidated regional management, regional financing, regional reporting, investment holding, acquisition vehicle, risk separation, and management of regional intellectual property. The appropriate structure depends upon the actual business, its activities, its people and the applicable legal and tax framework.
The question is not: “How sophisticated can we make the structure?” It is: “What is the simplest structure capable of supporting the business properly?”
When a Branch Can Make Sense
A branch may be appropriate where some of the following indicators apply — but these are indicators, not a universal decision rule:
- The parent wishes to maintain direct control of the overseas operation
- The overseas activity is relatively limited in scale
- Separate ownership of the overseas operation is not required
- The parent is prepared to accept direct legal exposure to the overseas operation
- Local law permits the intended activity through a branch
- The tax treatment of a branch is appropriate for the business
- Banking and contracting requirements can be met through a branch
When a Subsidiary Can Make Sense
A subsidiary may be appropriate where some of the following indicators apply — but these are indicators, not a universal decision rule:
- The overseas operation is expected to be substantial
- The operation will enter significant local contracts
- Local employees will be hired
- Local management with appropriate authority is required
- Legal separation between the parent and the overseas operation is commercially important
- External investors may participate in the overseas operation
- Local financing may be required
- A future sale of the overseas operation is possible
- Regulatory or customer expectations require a locally incorporated entity
These are indicators, not a universal decision rule. The appropriate structure depends upon the specific facts, the applicable legal and tax framework, and the commercial objectives of the business. Neither a branch nor a subsidiary is universally superior.
Building for Future Growth
Consider a hypothetical: a British engineering consultancy enters the UAE market. Initially, the operation involves one senior consultant, prospective clients, limited revenue and no major assets. At that stage, a limited form of presence may warrant consideration, subject to the activities permitted under UAE law and the intended operating model.
Several years later, the same operation has: a substantial local workforce, material regional turnover, significant professional liability exposure, offices, local banking relationships, major contracts and a potential investor interested in the regional business.
The structure appropriate to the first stage may not be appropriate to the second. The transition from one structure to another can involve legal, tax and regulatory complexity. Planning for the likely trajectory of the business from the outset can reduce the cost and disruption of restructuring later.
The structure should anticipate tomorrow's business — not merely today's registration.
This does not mean building a complex structure before it is needed. It means selecting a structure that can accommodate growth without requiring fundamental reconstruction.
Ten Common Expansion Errors
- Choosing the entity before defining the business. The structure should follow the operating model.
- Assuming a branch means no local tax. A branch may create a permanent establishment and local tax obligations.
- Assuming no branch registration means no PE. PE can arise without a formal branch registration.
- Automatically choosing a subsidiary. A subsidiary is not always the right answer.
- Ignoring liability. Legal separation through a subsidiary should not be overstated.
- Ignoring banking. Banking feasibility should be assessed before incorporation.
- Ignoring employment. Employment law, payroll and HR obligations vary by structure and jurisdiction.
- Ignoring transfer pricing. A subsidiary creates related-party transactions requiring appropriate pricing.
- Ignoring eventual exit. The structure should accommodate a future sale or restructuring.
- Building too much structure. A useful objective is the simplest structure capable of supporting the business properly.
The Coutts Expansion Test
Before selecting a legal structure for an international expansion, consider the following:
- Purpose: Why are we entering this market? What commercial objective does the overseas presence serve?
- Activity: What exactly will happen there? Employees? Contracts? Invoicing? Inventory? Premises? Assets? Regulated activity?
- People: Who will work there? Will they be employees of the overseas entity or the parent? Where will they be based?
- Contracts: Which entity will contract with customers? Which entity will be the employer? Which entity will own assets?
- Risk: Where should commercial liability sit? What is the parent's appetite for direct exposure to the overseas operation?
- Tax: What taxable presence may be created? What are the branch and subsidiary tax treatments? What are the withholding tax and treaty implications?
- Banking: What banking infrastructure is required? Is it available for the proposed structure?
- Regulation: What licences or local corporate forms are required? Does regulation determine the structure?
- Capital: Will the operation require investment or external finance? Will there be investors?
- Future: What might this business look like in five years? Will the initial structure accommodate that growth?
The Coutts Perspective
International expansion is often treated as a company-formation exercise. A business decides to enter a new market, selects a jurisdiction, and asks: “Which company type?” That approach puts the legal structure before the business question.
The better approach is to treat international expansion as a business-architecture exercise. The structure should follow the business. The business should not be shaped to fit the structure.
International expansion should not be treated as a company-formation exercise. It is a business-architecture exercise.
A branch may fit. A subsidiary may fit. A representative office may be enough initially. A regional structure may later become justified. What matters is alignment between the commercial activity, the legal structure, the tax position, the regulatory framework and the banking infrastructure.
Where these elements are materially misaligned, avoidable legal, tax, banking and operational complexity can arise. The objective is not to find the jurisdiction offering the fastest registration. It is to create an international operating structure that continues to make commercial sense after registration is complete.
The cheapest structure to establish is not necessarily the cheapest or easiest structure to operate.
Before You Expand
Before selecting a legal structure for an international expansion, determine:
- precisely what will occur in the new country;
- whether a legal presence is required;
- the permanent-establishment exposure under domestic law and the applicable treaty;
- the branch and subsidiary tax treatment in the relevant jurisdiction;
- the local licensing and regulatory requirements;
- which entity will employ local staff;
- the corporate tax position;
- the withholding tax and treaty access implications;
- the transfer-pricing implications of intercompany transactions;
- where liability should sit;
- the banking feasibility;
- the tax residence implications;
- the applicable substance and operational requirements;
- the profit repatriation mechanisms and their tax treatment; and
- the implications for future investment or disposal.
Only then should the final structure be selected and implemented.
The alignment that matters is: commercial activity → management → employees → contracts → risk → tax → banking → regulation → future strategy.
When these elements tell the same commercial story, the structure is easier to understand, operate and explain.
The structure should anticipate tomorrow's business — not merely today's registration.
