Do I Need to File a Tax Return?
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 (before taking off anything you claimed tax relief on) - Learn about the £1,000 Trading Allowance
- A partner in a business partnership
You may also need to send a tax return if you have any other untaxed income, such as:
- Money from renting out a property - Check if Rent-a-Room Relief applies (£7,500 tax-free)
- Tips and commission
- Income from savings, investments and dividends
- Foreign income
High Income Child Benefit Charge
If you or your partner claim Child Benefit and one of you earns over £60,000, you may need to file a return to pay the High Income Child Benefit Charge.
