When are the Self Assessment deadlines?

For the tax year that ended on 5 April 2026, HMRC must receive a paper return by 11:59pm on 31 October 2026, and an online return plus the tax you owe by 11:59pm on 31 January 2027. Check the GOV.UK page before you rely on it, deadlines move for some situations.

Do I need to file one at all?

It depends on what kind of income you had, not only how much. GOV.UK lists the situations that require a return: being self-employed as a sole trader earning more than £1,000, being a partner in a partnership, owing Capital Gains Tax, and several others, and it has a checker if yours is not clearly on the list.
