Self Assessment is a system HM Revenue and Customs (HMRC) uses to collect Income Tax.
Tax is usually deducted automatically from wages and pensions. People and businesses with other income must report it in a Self Assessment tax return.
The last tax year started on 6 April 2023 and ended on 5 April 2024.
Deadline for submitting an online return: If you’re doing an online tax return, you must submit it by midnight 31 January 2025.
Deadlines for paying tax you owe: You need to pay the tax you owe by midnight 31 January 2025.
There’s usually a second payment deadline of 31 July if you make advance payments towards your bill (known as ‘payments on account’).
You’ll usually pay a penalty if you’re late. You can appeal against a penalty if you have a reasonable excuse.
HMRC’s YouTube channel offers short videos to help you with your tax return including 'How do I tailor my Self Assessment tax return'.
