What is a Self-Assessment Tax Return?

Self-assessment is a way for HMRC to get income tax from people. Sometimes, people who have made money that HMRC doesn’t know about, like business profits, need to report that money to HMRC in a self-assessment tax return.

For a given tax year, the tax return lists how much money a person made and where it came from. Everyone who owns a business has to fill out a tax report online, send it to HMRC, and pay their tax bill by January 31 at midnight; the deadline for paying tax bills on paper is midnight, 31 October. HMRC must receive your tax return by 5 October if you have not already done so.

People use a self-assessment tax return to report their worldwide income and cash gains for a tax year. You would have had income from work in the tax year that finished on April 5, 2024. This is shown on your P45. You will also make money and spend money as a self-employed person. Fill out SA102 (work) and SA103 (self-employment) on a paper tax return, along with any additional self-assessment pages required. As a sole business or self-employed person, you should sign up for self-assessment if you haven’t already.

Who Must Send a Self-Assessment Tax Return?

Before knowing how to file self-assessment tax return, it is important to know who has to file a tax return. Before April 5, if any of the following were true for you, you need to send in a tax return:

  • You worked for yourself as a “sole trader” and made more than £1,000 (before deducting any amounts you can get tax back on).
  • You worked with someone else on a business deal.
  • If your total taxable income was more than £150,000, you had to pay Capital Gains Tax on things that you sold or “disposed of” that went up in value.
  • You also had to pay the High Income Child Benefit Charge.

Send a tax return if you have any cash that hasn’t been taxed, like:

  • Tips and commissions:
  • Money from savings, investments, and earnings;
  • The money comes from renting out a house.
  • Money from abroad

If you need to fill out a tax return but haven’t yet, you need to let HMRC know by October 5. If you sign up for Self Assessment, you can tell HMRC.

You can send your tax return to:

Claim some tax breaks for your income;

Show that you’re self-employed. (To get tax-free childcare or maternity allowance)
