Self Assessment tax returns
You must send a tax return if, in the last tax year (6 April to 5 April), you were:
self-employed as a ‘sole trader’ and earned more than £1,000
a partner in a business partnership
You will not usually need to send a return if your only income is from your wages or pension. But you may need to send one if you have any other untaxed income, such as:
money from renting out a property
tips and commission
income from savings, investments and dividends
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.
