For employees' NIC, see Employee Taxation.
Self-employed people pay:
- weekly Class 2 contribution of £2.10, unless they claim exception for small earnings (below £4,345).
- Class 4 NIC at 8% of taxable profits between £4,895 and £32,760. Profits over £32,760
will be charged at 1%. This is assessed and paid with the self-assessment income tax on profits.
Class 3 voluntary NIC may be paid at £7.35 per week by someone who is not in work but who wishes 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 at only 1%, and the overall liability will be settled at a later date.
