Setting up a UK branch or subsidiary of an overseas business

Tom South FCCA

Setting up business operations overseas is a big, exciting step for a growing business. The UK offers rich opportunities for expanding businesses, with a dynamic market, affluent consumers, skilled workforce and range of double taxation treaties.

The UK also has a well-established and stable legal system, making it a predictable and reliable place to do business.

Is it better to set up a subsidiary or branch?

There are different ways that a business presence can be established internationally. It is important to understand how these structures differ, as this will impact the legal status of the operation, its tax treatment and its liability.

Subsidiary Branch
Legal status A separate legal entity from your parent company based back home. An extension of your parent company.
Liability Limited liability means the assets of the parent company are protected against financial and legal risk. The parent company is also liable for all debts, obligations and risks faced by the branch.
Corporate Registration Must be registered in the UK via Companies House The overseas parent company must be registered as such at Companies House. As well as the UK branch being registered.
Tax Will be subject to UK Corporation Tax rules Tax position will vary. Although the usual position is the UK branch will need to file a corporation tax return and pay corporation tax in the UK
Filing requirements (Companies House) Annual accounts and confirmation statement will need to be filed at Companies House Depending on the size and audit status of the overseas parent company, it may need to file group accounts at Companies House along with the appropriate forms.

Why set up a subsidiary in the UK?

For the purposes of setting up a business presence in the UK, a subsidiary is typically recommended over a branch.

  • The subsidiary is a separate legal entity, so the parent company’s assets are protected from risk, debts and obligations of the subsidiary.
  • As a legal UK entity, a subsidiary may be seen as more credible and find it easier to establish business relationships, secure contracts, and gain customer trust in the UK.
  • A subsidiary can make its own decisions, adapt to local market conditions, and seize opportunities without constant oversight from the parent company overseas.
  • Subsidiaries file their own financial statements, which can greatly simplify accounting and reporting.

Registering a UK subsidiary

Your subsidiary must be registered with Companies House, which is the UK government’s official registry of companies. It is where information about company registration, incorporation/dissolution and public records can be accessed.

Requirements for registering a subsidiary with Companies House

In order to register your subsidiary as a private limited company (ltd.) in the UK, you must register with Companies House using the following information:

  • A company name for your subsidiary
  • A registered office address (which must be in the UK)
  • A minimum of 1 company director (who doesn’t have to be a UK resident)
  • Memorandum and Articles of Association

Legal compliance: Companies Act 2006

The legal framework under which all UK companies must operate is set out in the Companies Act 2006. This includes rules and regulations relating to company operations, company law, the duty of company directors, shareholder rights and information disclosure.

You can read the Companies Act 2006 in full on the UK Government website.
