How to Register as a Freelancer in the UK (Step-by-Step Guide)

Are you starting out as a freelancer in the UK? Here's your easy-to-follow guide on how to officially register your freelance business, ensuring you're compliant from the get-go.

Step 1: Decide Your Business Structure

Firstly, choose between operating as a sole trader or forming a limited company.

  • Sole Trader: Simpler, lower costs, suitable for individuals starting out.
  • Limited Company: Offers limited liability protection, separate legal entity, potentially more tax-efficient but involves greater responsibilities.

Most freelancers initially register as sole traders due to simplicity and lower costs.

Step 2: Register with HMRC

As a sole trader, you'll need to:

  • Register online through the HMRC website within 3 months of starting your freelance business.
  • You'll receive a Unique Taxpayer Reference (UTR) number, essential for your tax return.

Step 3: Set Up a Separate Bank Account

While not mandatory for sole traders, opening a dedicated business bank account simplifies bookkeeping and tax reporting.

Step 4: Understand Your Tax Obligations

As a freelancer, you'll typically:

  • File an annual Self Assessment tax return.
  • Pay Income Tax and National Insurance Contributions (NICs).
  • Keep accurate records of income and expenses for at least 5 years.

Step 5: Register for VAT (if applicable)

If your turnover exceeds £85,000 annually, you must register for VAT. Even below this threshold, voluntary registration might benefit your business by reclaiming VAT on expenses.

Step 6: Get Business Insurance

Depending on your freelance profession, consider policies such as:

  • Professional indemnity insurance
  • Public liability insurance
  • Equipment cover

Step 7: Keep Accurate Financial Records

Maintain thorough records of invoices, receipts, and expenses. Consider using bookkeeping software like Xero, QuickBooks, or Taxo, an AI-driven accounting tool designed specifically for freelancers.

    Common Mistakes to Avoid

    Business Bank Account Setup

    While not legally required for sole traders, a separate business account offers:

    • Easier bookkeeping - Clear separation of business and personal finances
    • Professional image - Business name on transactions
    • Tax preparation - Simplified expense tracking
    • VAT management - If you register for VAT later

    Popular options include:

    Equipment Insurance

    • Can be added to home insurance or separate policy
    • Especially important for mobile freelancers

    Next Steps After Registration

    1. Set up accounting system - Choose between spreadsheets or software
    2. Create invoice templates - Include all required information
    3. Plan your tax payments - Set up a separate savings account
    4. Consider business insurance - Get quotes for relevant coverage
    5. Join professional networks - Connect with other freelancers in your field

    Bonus Tips:

    • Stay proactive by setting aside approximately 25-30% of your income to cover tax payments.
    • Regularly review tax deductibles to maximise savings (home office costs, travel expenses, equipment, etc.).
    • Keep digital copies of all receipts and invoices using cloud storage or accounting software.
    • Consider quarterly reviews of your finances rather than waiting until year-end.
