What is a Self Assessment Tax Return?
Self Assessment is the system HMRC uses to collect income tax from individuals who don’t have it automatically deducted (such as through PAYE). The UK tax year runs from 6 April to 5 April the following year.
If you miss the deadline to file or pay, you’ll receive a penalty. Key deadlines are:
31 October – paper returns
31 January – online returns and payment deadline
From April 2026, Making Tax Digital (MTD for Income Tax) will affect many sole traders and landlords—changing how and when returns must be submitted.

Self Assessment FAQs
Can you help me file even if I’m behind?
Yes, we’ve helped many clients catch up and avoid penalties. We’ll guide you through the process step by step.
What’s the deadline for submitting a tax return?
The deadline for online tax returns is 31 January following the end of the tax year. But from April 2026, Making Tax Digital (MTD) means many sole traders and landlords will need to submit quarterly updates instead of just one annual return. We recommend preparing early to stay ahead of the changes.
