The Two Most Common Business Structures for UK Freelancers

When you start freelancing in the UK, you'll need to choose a legal structure. The two most common options are sole trader and limited company. Each has different implications for tax, liability, and how you invoice clients.

Sole Trader: Simple and Straightforward

As a sole trader, you and your business are legally the same entity. Key facts:

  • Register with HMRC for Self Assessment — simple online process
  • Pay Income Tax on profits (20%, 40%, or 45% depending on earnings)
  • Pay Class 2 and Class 4 National Insurance
  • Personally liable for any business debts
  • Less admin — just a Self Assessment tax return each year

Limited Company: More Tax Efficient at Higher Earnings

A limited company is a separate legal entity from you personally. Key facts:

  • Register with Companies House (takes about 24 hours, costs £50)
  • Pay Corporation Tax on profits (25% from April 2023 for profits over £250k)
  • Pay yourself a salary and dividends — often more tax efficient
  • Limited liability — your personal assets are protected
  • More admin — annual accounts, confirmation statement, payroll

Which Is More Tax Efficient?

Generally speaking:

  • Under £30,000/year — sole trader is usually simpler and similar tax burden
  • Over £40,000/year — limited company often becomes more tax efficient

Always consult an accountant before making the decision — the right answer depends on your specific circumstances.

Invoicing Differences

As a sole trader, your invoices use your personal name (or trading name). As a limited company, invoices must show your registered company name, company number, and registered address.

invly supports both structures — just set up your company details in your profile and every invoice will automatically include the right information.
