A Complete Guide to UK Company Registration for Expats

The United Kingdom is one of the easiest places in the world to start a business. Registering a company can take as little as 24 hours online, but for expats, the process may seem confusing due to visa rules, banking requirements, and compliance obligations.

This guide walks you step-by-step through everything you need to know about UK company registration as an expat.

1. Can Expats Register a Company in the UK?

Yes. The UK allows non-residents to form and own companies. You don’t even need to live in the UK to register a limited company. However:

• You must have a UK-registered office address.
• Your immigration status (visa) determines whether you can actively run the business in the UK.
• Tax residency rules may affect your obligations.

👉 Even if you register a UK company from abroad, you’ll need the correct visa to physically work and manage the business inside Britain.

2. Choosing a Business Structure

Before registering, decide on the right structure:

• Sole Trader
  • Easiest setup, but you are personally liable for debts.
  • Register with HMRC for Self-Assessment.
• Partnership
  • Two or more people share responsibilities and profits.
  • Each partner registers with HMRC.
• Limited Company (Ltd)
  • Most popular for expats.
  • A separate legal entity, offering liability protection.
  • Requires registration with Companies House.
• Overseas Company / UK Branch
  • If you already run a business abroad and want to expand to the UK.

3. Preparing to Register a Limited Company

To set up a company with Companies House, you’ll need:

• ✅ Company name (must be unique, not offensive, and end with “Ltd” or “Limited”)
• ✅ Registered office address in the UK (can be your office, accountant, or a virtual office service)
• ✅ At least one director (can be non-UK resident)
• ✅ At least one shareholder (can be you, or others)
• ✅ SIC Code (Standard Industrial Classification – describes your business activity)
• ✅ Memorandum & Articles of Association (rules governing your company – template provided by Companies House)

💰 Cost: £12 if registering online (via Companies House).

⏱ Timeframe: Usually approved within 24 hours.

4. Registering with HMRC

After registering with Companies House:

• Your company will automatically be registered for Corporation Tax.
• If you’re a sole trader, you must register separately with HMRC for Self-Assessment.
• If turnover exceeds £90,000/year (2025 threshold), you must also register for VAT.

5. Opening a UK Business Bank Account

A dedicated business bank account is strongly recommended (mandatory for limited companies).

Requirements:

• Passport + visa/BRP (Biometric Residence Permit)
• Proof of UK address (utility bill, tenancy agreement, or virtual office)
• Certificate of incorporation & company documents

💡 Tip for Expats: Digital banks like Tide, Wise, Monzo, Revolut Business are easier for newcomers than traditional banks.

6. Ongoing Legal & Compliance Obligations

Once your company is registered, you must:

• 📑 File annual accounts with Companies House
• 📑 Submit a Confirmation Statement every year
• 📑 File a Company Tax Return with HMRC
• 📑 Maintain accurate financial records
• 📑 Register for PAYE if hiring employees
• 📑 Stay compliant with data protection (UK GDPR) if handling customer data

Failure to comply can result in fines or company strike-off.

7. Visa & Immigration Considerations for Expats

Registering a company is not the same as being allowed to work in it. Expats must ensure they have the right visa. Common options:

• Innovator Founder Visa – for innovative business ideas with endorsement.
• Global Talent Visa – for leaders in specific industries.
• Skilled Worker Visa – usually tied to employment (not self-employment).
• Investor/Expansion routes – for overseas companies opening UK branches.

👉 Always check Home Office rules before starting operations.

8. Taxation for Expat Business Owners

• Corporation Tax: 25% (2025 rate) on company profits.
• Income Tax: On salaries or dividends you receive.
• National Insurance: Contributions required for directors and employees.
• Double Taxation: Check if your home country has a treaty with the UK to avoid being taxed twice.

9. Extra Considerations for Expats

• Business Insurance: Public liability, employer’s liability (mandatory if you hire staff), professional indemnity.
• Licenses & Permits: Some industries (hospitality, transport, finance) require specific licenses.
• Intellectual Property: Register trademarks, designs, or patents via UKIPO if you want brand protection.
