What Does National Insurance Go Towards?

The three things National Insurance pays for

By law, NI contributions go into the National Insurance Fund. The Fund pays out three categories:

1. State Pension. The Fund's biggest use. Around 55-60% of NI receipts go towards current State Pensions. The full new rate in 2026/27 is £241.30 a week. Our guide to how the State Pension works explains who gets the full amount.
2. NHS contribution. Each year, a fixed share of NI is moved to the NHS budget for England, Scotland, Wales and Northern Ireland.
3. Contributory benefits. Jobseeker’s Allowance, Maternity Allowance, Employment and Support Allowance and Bereavement Support Payment. Only people with a sufficient NI record get these.

Any money left in the National Insurance Fund at year end is held as a working balance. It is not moved to the general Treasury budget.

How your National Insurance contributions are spent

Recent figures from HM Treasury and the Office for Budget Responsibility show roughly this split for each pound of NI collected:

Exact percentages change from year to year as State Pension uprating, NHS funding and benefit caseloads change. The latest figures appear in the annual Government Actuary’s Department report on the National Insurance Fund.

National Insurance vs income tax: what is the difference?

NI and income tax look alike on a payslip, but they are separate taxes:

• What it is charged on. NI applies only to earned income, such as wages and self-employed profits. Income tax applies to nearly all income. That includes pensions, savings interest, dividends and rental income.
• What it funds. NI is hypothecated to the National Insurance Fund, which pays for pensions, the NHS and contributory benefits. Income tax goes into general government spending.
• Bands. NI is 8%, then 2% (employee). Income tax is 20% / 40% / 45% in England, Wales and Northern Ireland. Scotland has its own six income tax bands. NI is the same across the whole UK.
• State Pension age. Once you reach State Pension age, you stop paying NI even if you keep working. Income tax continues regardless of age.

Together, the two taxes give a basic-rate worker a marginal rate of 28% (20% income tax plus 8% NI) on each extra pound earned in the basic-rate band.

Do you get NI back as a pension?

Not in the sense of a personal account that pays you back. Each tax year in which you earn or get credited with NI counts as a ‘qualifying year’. You need:

• 35 qualifying years for the full new State Pension (£241.30 per week in 2026/27, after a 4.8% triple lock rise in April 2026)
• 10 qualifying years at minimum to receive any State Pension at all

If you take a career break, you may still get NI credits. This can happen while you claim benefits, take parental leave or care for a relative. Voluntary Class 3 contributions can fill gaps in some years if you would otherwise fall short of the 35-year mark. The State Pension forecast tool at gov.uk/check-state-pension shows your record and what you are projected to receive.

It helps to be clear about scale. Even the full new State Pension is £12,547.60 a year over 52 weeks. This is why most people combine it with a workplace or private pension. NI buys you the floor, not the whole retirement.

How much do you pay in National Insurance?

For employees in 2026/27:

• 0% on earnings below the £12,570 Primary Threshold
• 8% on earnings between £12,570 and £50,270
• 2% on earnings above £50,270

The main rate fell from 12% to 10% in January 2024, then from 10% to 8% in April 2024. Self-employed Class 4 NI is 6% between £12,570 and £50,270, then 2% above. Class 2 contributions for the self-employed were abolished in April 2024.

Little changed for 2026/27. Employee rates and thresholds are frozen. Employers still pay 15% on earnings above £5,000. The only Class 1 change was the Lower Earnings Limit, which rose from £6,500 to £6,708 a year (£125 to £129 a week). That limit decides whether a low-paid year counts on your NI record. It does not decide how much you pay. On the self-employed side, the Class 2 Small Profits Threshold rose from £6,845 to £7,105. The voluntary Class 2 rate went from £3.50 to £3.65 a week. Our full National Insurance guide works through the calculation on real salaries.

The take-home pay calculator shows the NI deducted from any salary. It also shows income tax and pension contributions.

Why NI matters for younger workers

For UK 18 to 25 year-olds starting work, NI can look like just another tax taken off the payslip. Here is why it matters in practice:

• Each year of NI builds your State Pension entitlement. Once you have 35 qualifying years, it is worth £12,547.60 a year for life from State Pension age. That figure is based on the 2026/27 full rate of £241.30 a week.
• Gaps matter later. Years with no NI credits cannot be reclaimed cheaply once they are more than 6 years old.
• Contributory benefits such as Maternity Allowance and Jobseeker’s Allowance need a recent NI record. If you only worked informally on a self-employed basis without paying Class 2, you may not qualify.
• Part-time and term-time work still counts. You need to earn at least £6,708 a year (£129 a week) from one employer in 2026/27. Below that, the year is blank unless you get NI credits another way.

Checking your NI record on gov.uk each year takes about two minutes. It is the single best way to spot gaps early.

The other half is what that money will buy when you get there. The State Pension rises each April under the triple lock. The lock is meant to keep pace with prices or wages. So it helps to understand how inflation erodes fixed sums over a working life. Anything you save on top, in an ISA or a pension, sits outside the NI system entirely.
