When is the tax return deadline for the 2022-23 tax year?

The self-assessment tax return deadline for the 2022/23 tax year is 31st October 2023 for those who complete paper tax returns (unless you are a trustee of a registered pension scheme or a non-resident company). If you complete your tax return online, the deadline is 31st January 2024.

If you have an accountant, you should speak to them to confirm which deadline you need to meet. Most people complete their tax returns online, so the 31st January deadline is the one most widely used.

It is important to get your tax return information to your accountant as soon as possible following the end of the tax year (5th April). This gives your accountant enough time to complete your tax return ahead of HMRC's filing deadline.

Ensuring the work is not rushed will mean that there is more time for you to check through your tax return ahead of submission. You will also be able to budget for any tax that may be payable to HMRC by 31st January.  If you are due a refund from HMRC you will also receive this earlier.
