About National Insurance

Introduced in 1911, National Insurance is a mandatory tax paid by most workers in the UK.

National Insurance contributions can build up your entitlement to certain benefits, including state pensions.

The money is collected by HMRC, the UK tax authority. For most people this happens automatically as the sums are deducted by employers as part of their payroll processes (PAYE).

Both employees and employers make an NI payment. Employees see this as a deduction from their gross salary, and it shows up as a separate line on their payslips. The self-employed must make their NI payments as part of their annual tax return.

If you are employed, you pay Class 1 National Insurance. The amount of NI you pay will depend on how much you earn.
