National insurance contributions (NIC) - Frequently Asked Questions

National insurance is a tax on your earnings. This guide covers some basic information about NIC.

Frequently Asked Questions

What if I have more than one job?

Unless you are a director of a company, each employment you have is looked at separately and each has the weekly £190 lower limit primary threshold.

If, in the 2022/23 tax year you have two jobs, you may be able to defer paying Class 1 national insurance contributions. You can find out more about the conditions for this on the Gov.UK website

You do this on form CA72A 'Application for deferment of payment of class 1 NICs' on the Gov.UK website. If you need them, there are also CA72A form guidance notes.  

What happens if I am employed and self-employed?

If you are both employed and self-employed, you need to pay both Class 1 NIC on your employed income and Class 2/4 NIC on your self-employed income. Class 2 is now paid at the same time as Class 4 when you file your self-assessment tax return. How much you pay depends on your combined income from all your jobs.  HMRC will let you know how much Class 2 and Class 4 is due after you've filed your self-assessment tax return. If you pay the maximum amount of annual NIC by way of Class 1/Class 2, you may not need to pay any more.
