Self Assessment Tax Returns

Who Needs to Complete a Tax Return?

You must send a tax return if, in the last tax year (6 April to 5 April), any of the following applied:

  • you were self-employed as a ‘sole trader’ and earned more than £1,000 (before taking off anything you can claim tax relief on)

  • you were a partner in a business partnership

  • you earned £100,000 or more

You may also need to send a tax return if you have any untaxed income, such as:

  • some COVID-19 grant or support payments

  • money from renting out a property

  • tips and commission

  • income from savings, investments and dividends

  • foreign income

Other Reasons for Sending a Return

You can choose to fill in a tax return to:

  • claim some Income Tax reliefs

  • prove you’re self-employed, for example to claim Tax-Free Childcare or Maternity Allowance

If You Get Child Benefit

If your income (or your partner’s, if you have one) was over £50,000, you may need to send a return and pay the High Income Child Benefit Charge.

Making Tax Digital

Making Tax Digital is changing the way that businesses submit their Income Tax Self Assessment (ITSA) returns.

From April 2026, self-employed individuals and landlords with an income of more than £50,000 will be required to keep digital records and provide quarterly updates on their income and expenditure to HMRC through MTD-compatible software. Those with an income of between £30,000 and £50,000 will need to do this from April 2027. Most individuals will be able to join voluntarily beforehand meaning they can eliminate common errors and save time managing their tax affairs.

Xero software is compatible with MTD.
