Self Assessment — common questions
When is the Self Assessment deadline?
Online tax returns must be filed by 31 January following the end of the tax year (5 April), and any tax owed is also due by 31 January. Paper returns are due by 31 October. If you are new to Self Assessment you need to register by 5 October.
What are the penalties for a late tax return?
HMRC charges £100 as soon as an online return is late. After 3 months, daily penalties of £10 apply for up to 90 days, with further penalties at 6 and 12 months. Interest is also charged on tax paid late.
What is Making Tax Digital for Income Tax?

It started in April 2026 for those with qualifying income over £50,000, with lower thresholds following. We help you get set up and stay compliant.
