For employees' NIC, see Employee Taxation.
Self-employed people pay:
- weekly Class 2 contribution of £2.75, unless they claim exception for small earnings (below £5,885).Usually
paid monthly or six-monthly by direct debit.
- Class 4 NIC at 9% of taxable profits between £7,956 and £41,865. Profits over £41,865 will be charged
at 2%. This is assessed and paid with the self-assessment income tax on profits.
Class 3 voluntary NIC may be paid at £13.90 per week by anyone not in work but who wants to maintain state pension rights.
Someone who is both employed and self-employed will pay Class 1, Class 2 and Class 4 NIC. It is possible
to apply for deferment of Class 4 so that the Class 1 paid on earnings can be taken into account. Class 4
will then be charged through self-assessment at only 2%, rather than 9%, and any further liability will be settled at a later date.
