Submit your Self Assessment return earlier this year

HMRC have seen a growing trend in customers submitting their Self Assessment returns early. In the last five years the number of customers choosing to file their return on the first day of the tax year has almost doubled.

You have until the 31 January 2023 to send HMRC your Self Assessment tax return and to pay any tax you may owe, but why wait? 

How to file your return 

All the information you need is online. Please go to GOV.UK for help with: 

  • what you’ll need to fill in your tax return 
  • furlough payments, Self-Employment Income Support Scheme grants or other COVID-19 support schemes  
  • what to do if you have paid too much tax 
  • paying your bill 
  • getting further support
