Who needs to complete a Self Assessment tax return?

Not everyone needs to complete a tax return; if your tax affairs are straightforward you may already pay all of the tax due on your earnings or pensions through your tax code.

If you have more complicated tax affairs, even if you already pay tax through your tax code you may need to complete a tax return.

The most common reasons for needing to complete a tax return are:-

  • You are self-employed.
  • You are a company director, minister or Lord.
  • You are a trustee.
  • You are receiving foreign income.
  • Your annual income is over £100,000.
  • You or your partner receive Child Benefit and your income is over £50,000.
  • You have Capital Gains Tax to pay.

The full list of who needs to complete a Self Assessment Tax Return can be found on HMRC’s website.

Deadlines for sending in your tax return:

Paper returns

If you send a paper tax return it must reach HMRC by midnight on 31 October. So for the 2023-24 tax year (ending on 5 April 2024), the deadline for paper returns is midnight on 31 October 2024.

Online returns

Your online tax return must reach HMRC by midnight on 31 January. So for the 2023-24 tax year, the deadline for online returns is midnight on 31 January 2025.  There are very few exceptions.

Penalties if you miss the tax return deadline

If you miss the deadline, the longer you delay, the more you’ll have to pay. So it’s important that your tax return is filed on time.  Full details of the penalties payable for late returns can be found on the HMRC website.
