The October paper tax return deadline

The due date for a self-assessment tax return depends on:

• the date of issue of the notice that HMRC send you to tell you to complete a tax return, and
• whether you complete your tax return on paper or online.

The deadline for submitting a paper tax return to HMRC is 31 October 2024. However, if you’re filing online, you have until 31 January 2025.

There are several different deadlines for filing a self-assessment tax return, depending on the method you choose to complete it.
