An overseas company starts selling to UK clients from its home market. After a year, it plans to hire a representative, lease workspace and handle customer support locally. Its founder asks whether the company needs a local presence. The answer starts with what the founder means by a presence. It could be a practical requirement to serve clients, a company registration obligation, a taxable permanent establishment or a condition for obtaining a licence. One change can raise several of these questions.
Use the UK as a worked example if you are coming here, or use the same questions to brief advisers for another market. Write down what will happen locally in the first three months and what could change if the operation grows. That gives the advisers a specific fact pattern to review. It also gives the business a basis for deciding what kind of operation it needs.
Map how the company will enter the market
Describe whether you plan to sell remotely, send staff on visits, use a distributor, employ people locally or operate from fixed premises. Record who speaks to customers, who decides terms, which company signs and where work is delivered. Check who owns stock, equipment, customer records and local accounts. Give dates and estimated volumes. A few meetings during a trial can raise different questions from regular trading through a space the company controls.
Ask what the customers expect. Some may need local billing, support during local hours, particular licences or a local address to which notices can be sent. Others may be comfortable buying from the existing company. Confirm the practical reason you are considering a branch or a subsidiary. This can help separate a legal requirement from a commercial preference when the advisers compare arrangements.
Separate the four local questions
- Company registration. Ask whether the foreign company must register a local establishment, or whether a separately incorporated company is needed for the activity. Check the paperwork, deadlines, responsible officers and ongoing disclosures.
- Corporate income tax. Ask whether activities create a permanent establishment or affect the company’s tax residence. Review local law and any treaty. If taxable presence exists, ask which profits are attributed to it and which accounts and filings are needed.
- Employment and licences. Ask whether the company can employ staff directly, which registration applies and what authorisations are needed for regulated work. Include insurance, workspace and people who will travel.
- VAT or sales tax. Give the adviser a sample invoice and a description of the supply. Check registration and reporting separately from corporate income tax. The location of the customer, the nature of the sale and how you deliver can matter.
Companies House guidance says an overseas company that opens a UK establishment, such as a branch or place of business with a physical presence, must file the registration documents within one month of opening. It also explains that doing business in the UK can fall outside that registration requirement where there is no physical presence. Read the definitions and examples, then ask about your own workspace and activities. The corporate tax, VAT and employment questions still need to be considered separately.
HMRC’s UK permanent establishment guidance describes fixed places through which business is carried on and certain agent arrangements. It uses a tax definition, which is a separate test from Companies House registration. A foreign business can also face VAT registration questions when it makes taxable supplies in the UK. Give the advisers a description of what will actually be sold and where, including which entity delivers and bills for it.
Compare a branch with a local company
A branch generally forms part of the foreign company. A subsidiary is a distinct legal entity with its own obligations. Compare who will hold contracts, employ staff, carry liabilities and own assets under each option. Ask about funding, accounting, tax, liability and how the operation could later be sold or closed. Where the new operation needs support from the existing business, describe what services will be provided, how costs will be allocated and what agreements are required.
For example, an overseas software business first sells subscriptions to UK companies from abroad. It then considers giving a local team authority to negotiate new contracts from an office. The first phase requires a review of cross-border sales and tax. The second adds questions about a physical base, staff and authority to act. If a UK subsidiary takes on the new contracts, the business also needs to decide what happens to existing customers and how the two entities share software and support. The facts change one step at a time.
Check what the first invoice will require
Take one likely customer order and ask what needs to happen for the business to accept it. Confirm the seller on the contract, whether it can issue an invoice the customer can pay and where the money should go. Ask the accountant to check the tax treatment and whether the customer expects to deduct anything. If a local licence or registration must be shown on paperwork, identify the deadline. The exercise is especially useful where the first customer will pay for both a product and installation or ongoing support.
Do the same with your first supplier and first employee. Decide who signs, who pays and where records will be kept. Compare a version in which the existing company keeps responsibility with a version in which a new entity contracts locally. Look at the amount of working capital each would need while it waits for customers to pay, including the initial cost of payroll and deposits. That can distinguish a workable structure from one that only looks simple in an organisation chart.
Plan a way to leave or expand
Before committing to a lease, check what happens if sales take longer than you expect. Record the earliest point at which you can review the decision, what notice is required and how the company would continue to serve existing customers. For a growing operation, ask how you would add a second team or transfer activity to another entity. Include who would notify customers and take responsibility for the records.
Give the advisers those possible next steps. They can tell you which changes could require a new registration, consent or tax review and help put them on the calendar.
Set milestones before the company starts local work
- Agree the activity map. Use real examples of customers, staff, office space and payments. Record the starting arrangement and the next planned step.
- Get answers by topic. Assign corporate registration, tax, employment, licensing and customer contracts to named people. Ask which steps must happen before work starts and which follow afterwards.
- Price the operating costs. Include filings, payroll, local insurance, office commitments and the time needed to maintain records in more than one country.
- Set review triggers. Recheck the position before leasing space, granting sales authority, employing someone locally or signing a contract through a different entity.
Keep an agreed record of the first local transaction, the date any office opens and the first day each person works there. These dates can matter for filings and will help the adviser compare the plan with what happened. Schedule a review after the first few customers or the first full payroll cycle. If the volume, role or location of work has changed, revisit the analysis before expanding the operation.
