What is VAT?

    You must register for VAT if your business’s annual taxable turnover is more than £90,000.
  • Included
    If your business earns less than £90,000 you can choose whether or not to register.
  • Included
    You’re not allowed to register if you only sell goods and services that are VAT-exempt.

  3. Categorising expenses

    By separating your VAT-inclusive and VAT-exclusive prices you’ll get a clearer picture of your finances
