From 2015-16 onwards, the collection of Class 2 contributions will be through the self-assessment system. This means that Class 2 NICs can now be paid together with income tax and Class 4 NICs in one chunk on the 31 January following the end of the relevant tax year. In the past, most people have paid Class 2 contributions monthly by direct debit. Following the final payment in July 2015, HMRC have cancelled such direct debit payments, ready for the switch over to the new system of payment under self-assessment. However, those who wish to continue paying their contributions more regularly can set up a Budget Payment Plan (assuming they are up to date with their self-assessment payments) and make payments weekly or monthly by direct debit in advance of the payment deadlines.   For those who do not opt to use a Budget Payment Plan, the payment date for the 2015-16 liability (£145.60) will be due on 31 January 2017. Self-employed traders will need to budget for this lump sum payment accordingly.
