A foreign branch is part of its parent company. A subsidiary is a separate company owned by that parent. That legal difference affects liability, registrations, tax analysis and the documents a bank will ask to see. The better choice depends on the market plan, not a generic "low-tax" label.
What is the practical difference between a branch and a subsidiary?
A branch lets the parent operate directly in the target market. A subsidiary creates a local legal vehicle with its own records, governance and liabilities. The UK government describes a branch as a UK office of the overseas company and says it is not a separate legal entity; it describes a subsidiary as a separate UK legal entity.
Business.gov.uk's official market-entry guidance also notes that a parent is liable for a branch's debts and obligations, while a parent will generally have no legal liability for a subsidiary's debts and obligations. Guarantees, fraud, director duties and local law can change the outcome. Get advice before treating ring-fencing as absolute.
Which structure is better for liability and contracts?
A subsidiary is usually the cleaner choice when the local business will sign material customer contracts, employ staff, hold inventory or accept product risk. It separates the operating entity from the parent on the corporate record. A branch can suit a controlled, narrow launch when the parent wants direct ownership of the local operation and accepts the parent-level exposure.
How does tax differ?
There is no universal tax winner. Tax depends on the market, the parent jurisdiction, where management and people work, treaty access, permanent-establishment rules, VAT and the way profits are funded or distributed. Build a model before incorporation. It should show tax filings, withholding, transfer-pricing support, loss treatment and the cost of moving cash back to the parent.
For a concrete example, the Turkish Investment Office says company and branch registry processes run through MERSIS. Its guidance also lists foreign-document formalities for company formation, including notarisation, apostille or consular ratification, translation and Turkish notarisation. Those documents affect timetable and cost before the tax model is even implemented.
Does a subsidiary make banking easier?
Neither form guarantees an account. Banks and payment institutions assess the actual ownership chain, authorised signers, expected activity, source of funds, contracts and local substance. A subsidiary can make the local operating picture easier to document. A branch can make the parent connection clearer. Prepare the same evidence pack either way: group chart, registry extracts, tax identifiers, beneficial-owner information, sample invoices and a short activity narrative.
What needs to be registered?
Registration is jurisdiction-specific. In the UK, an overseas company needs to register a UK establishment when it has a physical place of business or branch carrying on business, and the official guidance says the filing is due within one month of opening. The same guidance was updated on 2 April 2026. Do not use this UK rule as a deadline for another country.
Decision checklist
- Choose a branch when the parent will directly control a limited local operation and can accept parent exposure.
- Choose a subsidiary when local contracts, staff, assets, investors or risk separation justify separate governance.
- Model tax and cash repatriation before signing leases or customer commitments.
- Build the banking and compliance pack before submitting the first application.
Frequently asked questions
Is a branch a separate legal entity?
No. A branch is normally part of the overseas parent. Local law determines registration and tax consequences.
Can a subsidiary be wholly owned?
Yes. A parent can own all shares while the subsidiary remains a separate legal entity.
Which structure is faster?
It depends on local filings and document readiness. Foreign corporate documents often add apostille, translation and representative steps.
Should banking decide the structure?
Banking should inform the decision, but it should not replace tax, liability and operating analysis.
