Things to Include on your Self Assessment Tax Return
You need to file a return for the 2025/26 tax year (6 April 2025 to 5 April 2026) by 31 January 2027 if any of the following applied:
- you were self-employed as a ‘sole trader’ and your income was more than £1,000, before taking off anything you can claim tax relief on
- you were a partner in a business partnership
- you received more than £1,000 in income from renting out a property
- you had Capital Gains Tax to pay when you sold or ‘disposed of’ something that increased in value, such as a second property or shares. You also need to complete the capital gains pages if your total disposal proceeds were more than £50,000, even if you did not make a gain
- you or a partner who lives with you received Child Benefit, and either of you had income over £60,000. The charge increases gradually up to £80,000, at which point it cancels out the Child Benefit entirely
