Frequently Asked Questions

What does National Insurance pay for?

NI contributions fund state benefits including the State Pension, NHS, statutory sick pay, and unemployment benefits. Your NI record affects your pension entitlement.

Do I pay NI after State Pension age?

No. Once you reach State Pension age, you stop paying employee NI. You'll be put on Category C. However, your employer still pays employer NI on your salary.

Is NI the same as income tax?

No. NI is a separate contribution that goes to the National Insurance Fund. Income tax goes to general government spending. Both are deducted from your salary, but they have different thresholds and rates.
