An online return for the tax year ending 5 April must be filed by 31 January the following year, and any tax owed is due the same day. Paper returns are due earlier, by 31 October. If you also make payments on account, the second one falls due on 31 July.

We aim to have returns finished well before Christmas so you know your January figure in good time.
