What Does National Insurance Go Towards?

The three things National Insurance pays for

By statute, NI contributions are routed to the National Insurance Fund. The Fund pays out three categories:

1. State Pension. The biggest single use of the Fund. Around 60% of NI receipts go towards current State Pensions.
2. NHS contribution. A fixed share of NI is transferred each year to the NHS budget across England, Scotland, Wales, and Northern Ireland.
3. Contributory benefits. Jobseeker’s Allowance, Maternity Allowance, Employment and Support Allowance, and Bereavement Support Payment. These are paid only to people with a sufficient NI record.

Anything left in the National Insurance Fund at the end of the year is held as a working balance, not transferred to the general Treasury budget.

How your National Insurance contributions are spent

Recent figures published by HM Treasury and the Office for Budget Responsibility show roughly this split per pound of NI collected:

Exact percentages move year to year as State Pension uprating, NHS funding deals, and benefit caseloads change. Up-to-date figures are published 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 similar on a payslip but they are different taxes:

• What it is charged on. NI applies only to earned income (wages, self-employed profits). Income tax applies to nearly all income, including pensions, savings interest, dividends, and rental income.
• What it funds. NI is hypothecated to the National Insurance Fund (pensions, NHS, contributory benefits). Income tax goes into general government spending.
• Bands. NI is 8% then 2% (employee). Income tax is 20% / 40% / 45% (rUK).
• 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 mean a basic-rate worker faces a marginal rate of 28% (20% income tax + 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. Every tax year you earn or are credited with NI counts as a ‘qualifying year’. You need:

• 35 qualifying years for the full new State Pension (£230.25 per week in 2025/26)
• 10 qualifying years at minimum to receive any State Pension at all

If you take a career break, you may still get NI credits while claiming benefits, on parental leave, or caring for a relative. Voluntary Class 3 contributions can fill gaps for 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.

How much do you pay in National Insurance?

For employees in 2025/26:

• 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 dropped from 12% to 10% in January 2024 and 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 self-employed contributions were abolished in April 2024.

The take-home pay calculator shows the NI deducted on any salary alongside income tax and pension contributions.

Why NI matters for younger workers

For UK 18 to 25 year-olds entering the workforce, NI looks like another tax that disappears off the payslip. The practical reason it matters:

• Each year of NI builds your State Pension entitlement, which is worth roughly £12,000 a year for life from State Pension age once you have 35 qualifying years.
• Gaps now matter later: years you do not earn NI credits cannot be reclaimed cheaply once they are more than 6 years old.
• Contributory benefits like Maternity Allowance and Jobseeker’s Allowance require a recent NI record. If you have only worked self-employed informally without paying Class 2, you may not qualify.

Checking your NI record annually at gov.uk takes about two minutes and is the single best way to spot gaps early.
