Class 2 national insurance contributions in previous years were paid separately from your tax, however, they are now paid in line with your tax return.
Class 2 NIC is a fixed weekly rate of £3 for 2019/20 assuming your profits are above the small profits threshold which, for 2019/20, is £6,365 or lower. If you do not make profits of more than £6,365 then you are exempt from making any class 2 NIC payment.
The amount of class 2 NIC due is based on the number of weeks in the tax year of self-employment. For example, if your self-employment began on the 1st of February 2020, then you should pay 9 weeks of class 2 NIC (which is £3 x 9 = £27) as there are 9 weeks between the 1st of February 2020 and the 5th of April 2020.
