How your income tax is calculated

As a self-employed you have to pay your income tax and national insurance contributions yourself during your annual self assessment. Our calculator helps you quickly assess how much payment is due.

However you may be eligible for a tax refund when:

  1. You already made tax payments for the year but your annual income ended up smaller than planned
  2. You have done things that qualify for tax relief (made private pension contributions, give to charity, etc)

In your case when you earn £49,000:

Income tax breakdown
