As discussed in E1.250, under self assessment, income tax, capital gains tax plus any Class 2 and Class 4 national insurance contributions (NIC) due in relation to the tax year is due by 31 January after the end of the tax year¹. However, where the taxpayer notified their chargeability to tax by 5 October after the end of the tax year, but HMRC does not issue the notice to file the return until after 31 October, the due date is three months from the date on which the notice to file is issued².

To preserve a flow of tax to HMRC, where the income tax and any Class 4 NIC due for the tax year (ie the liability less tax deducted at source) is sufficiently large (see below), payments on account may be payable. If payments on account are due, two equal payments are due by³:

   •ÌýÌýÌýÌý 31 July following the end of the tax year
