National Insurance (NI) is the second largest deduction from your UK pay packet after income tax — yet many people do not fully understand how it works.
| Earnings Band | NI Rate | Annual Threshold |
|---|---|---|
| Below Lower Earnings Limit | 0% | Below £6,396 |
| Between LEL and Primary Threshold | 0% (but NI record protected) | £6,396–£12,570 |
| Between Primary Threshold and Upper Earnings Limit | 8% | £12,570–£50,270 |
| Above Upper Earnings Limit | 2% | Above £50,270 |
| Annual Salary | Annual NI | Monthly NI |
|---|---|---|
| £20,000 | £598 | £50 |
| £30,000 | £1,398 | £117 |
| £40,000 | £2,198 | £183 |
| £50,000 | £2,998 | £250 |
| £60,000 | £3,196 | £266 |
| £80,000 | £3,596 | £300 |
You can check your NI record and State Pension forecast online at gov.uk/check-national-insurance-record. If you have gaps in your record (years where you did not work or claim credits), you may be able to buy voluntary NI contributions at Class 3 rates — currently £824.20 per year — to top up your State Pension entitlement.
Buying one missing NI year for £824 can add £329/year to your State Pension. If you live 20 years in retirement, that is a £6,580 return on £824 invested — an exceptional deal.
