How Much Is National Insurance – UK Rates and Thresholds 2024/25
UK workers currently face an 8% National Insurance contributions rate on earnings between £242 and £967 per week, following significant reductions implemented in April 2024. The exact amount deducted from your salary depends on your employment status, income level, and which National Insurance class applies to your work.
Self-employed individuals operate under a separate structure combining flat-rate weekly payments with profit-based percentages. Both employees and employers must navigate distinct thresholds that determine when contributions begin and end.
Figures from HMRC’s official guidance establish the baseline for all calculations until the next fiscal adjustment.
What are the current National Insurance rates?
The 2024/25 tax year brought substantial changes to contribution percentages across all categories. Employees now retain more take-home pay compared to the previous year, while employers continue bearing higher percentage burdens on wages above specific thresholds.
8% on earnings between £242–£967 weekly; 2% above £967
13.8% on wages exceeding £175 per week
£3.45 fixed weekly charge for profits above £6,725
8% on profits between £6,396–£50,270 annually
Key developments for the current tax period include:
- Reduced employee burden: The main rate dropped from 10% to 8% in April 2024
- Historical context: This follows an earlier reduction from 12% to 10% implemented January 2024
- Employer consistency: Secondary contributions remain at 13.8%, unchanged from previous years
- Self-employed alignment: Class 4 rates now match employee rates at 8%
- Threshold stability: Primary and secondary thresholds frozen at 2023/24 levels
- Upper limits: Contributions decrease significantly above £967 weekly

| Class 1 (Primary) | Employee | 8% / 2% | £242–£967 pw | Reduced from 10% |
| Class 1 (Secondary) | Employer | 13.8% | Above £175 pw | Unchanged |
| Class 2 | Self-employed | £3.45 weekly | Profits > £6,725 | Voluntary below threshold |

How much National Insurance do I pay?
Calculating employee deductions
Your weekly gross pay determines the exact deduction. Earnings below £242 incur zero contributions. Between £242 and £967, you surrender 8% to National Insurance. Above £967, the rate drops to 2% on the excess.
Annual salaries translate differently depending on weekly distribution. A £30,000 yearly income—roughly £577 weekly—generates approximately £268 in monthly contributions, though individual circumstances vary.
For earnings of £600 weekly: 0% on the first £242, 8% on the next £325 (£20.60), and 0% on the remainder. Weekly deduction equals approximately £26.
Employer responsibilities
Employers pay 13.8% on earnings above £175 weekly, creating a substantial additional cost beyond gross wages. Institute for Fiscal Studies analysis confirms this rate applies uniformly regardless of income level above the threshold.
Exceptions exist for specific demographics. Workers under 21, apprentices under 25, and veterans trigger zero employer contributions up to £967 weekly. Freeport and Investment Zone employers enjoy 0% rates between £175 and £481 weekly.
What is the National Insurance threshold?
Employee thresholds
The Primary Threshold stands at £242 weekly (£1,048 monthly / £12,570 annually). Below this, employees contribute nothing while still building entitlement to certain benefits. The Lower Earnings Limit (£123 weekly) marks the minimum for benefit accrual without payment.
The Upper Earnings Limit caps the 8% rate at £967 weekly (£50,270 annually). All earnings beyond this attract only 2% contributions, significantly reducing the marginal rate for high earners.
Employer thresholds
Employers begin paying at £175 weekly (£9,100 annually), lower than the employee threshold. This creates a band between £175 and £242 where only employers pay, not employees.
Legislation for 2025/26 indicates the employer threshold will drop significantly to £96 weekly, though employee thresholds remain static.
What are self-employed National Insurance rates?
Class 2 contributions
Self-employed individuals pay £3.45 weekly when profits exceed £6,725 annually. Below this Small Profits Threshold, payment remains voluntary but preserves benefit entitlements. Tax guidance charities recommend voluntary payments for those with low profits to maintain their contribution record.
From April 2025, the weekly Class 2 rate increases to £3.50, representing a 5p adjustment from current levels.
Class 4 profit-based rates
Profits between £6,396 and £50,270 attract 8% Class 4 contributions, mirroring employee rates. Profits above £50,270 incur 2%. This creates parallel structures between employed and self-employed workers, though the self-employed lack employer contributions entirely.
Accountancy experts note this alignment represents the most significant harmonization between employment statuses in recent fiscal history.
Unlike employees whose contributions deduct immediately through PAYE, self-employed individuals settle Class 2 and Class 4 liabilities through annual Self Assessment tax returns, creating potential cash flow planning requirements.
When did National Insurance rates last change?
Recent years witnessed unprecedented volatility in contribution rates. The timeline reflects shifting fiscal priorities between revenue generation and worker relief.
- November 2022: Rates held at 12% (employee) and 13.8% (employer) following abolition of the 1.25% Health and Social Care Levy
- November 2023: Autumn Statement announces reduction from 12% to 10% effective January 2024
- January 2024: Employee rate cuts to 10% mid-tax year, implemented through adjusted tax codes
- March 2024: Spring Budget announces further reduction to 8% from April 2024
- April 2024: Current 8% rate implemented for new tax year; Class 4 aligns at 8%
- April 2025 (scheduled): Employer secondary threshold reduces to £96 weekly; Class 2 rises to £3.50
These adjustments collectively represent a four-percentage-point reduction for standard employees within fifteen months.
What remains certain about future National Insurance?
Distinguishing confirmed legislation from speculation helps financial planning. Current statutory instruments establish specific parameters through April 2025, while beyond that date remains subject to parliamentary process.
| Established Information | Uncertain Elements |
|---|---|
| 2024/25 rates fixed until April 2025 | Potential 2025 Budget revisions |
| Employer threshold dropping to £96 pw April 2025 | Whether employee rates will hold at 8% |
| Class 2 increasing to £3.50 weekly | Possible abolition or merger of Class 2 |
| Upper Earnings Limit frozen at £50,270 | Indexation of thresholds beyond 2025/26 |
| 13.8% employer rate maintained | Political commitments to further reductions |
Financial advisors suggest monitoring the Autumn Budget for potential 2025/26 announcements, as previous years demonstrated mid-year rate adjustments remain possible.
Why did National Insurance rates change in 2024?
The 2024 reductions form part of broader cost-of-living interventions designed to increase disposable income without triggering inflationary wage spirals. Treasury projections indicated that reducing the tax burden on work would encourage labor market participation while offsetting frozen personal allowance thresholds.
For self-employed workers, aligning Class 4 rates with employee contributions addressed long-standing equity concerns. Previously, self-employed individuals paid different percentages despite receiving identical state pension entitlements. The published rates documentation confirms this harmonization as a permanent structural change rather than a temporary measure.
Understanding these shifts helps contextualize payslip deductions. Those reviewing household budgets might also examine fixed costs like Hastings Direct Car Insurance – Reviews, Pricing and Coverage 2025 to assess overall financial positioning alongside tax changes.
Where do these official figures come from?
All published rates derive from statutory instruments issued by HM Revenue & Customs, with official guidance updated following each fiscal event. The figures undergo verification through multiple channels including payroll software providers and professional accounting bodies.
“The secondary threshold for 2024-25 remains at £175 per week, with specific provisions for Freeport employers and certain exempt categories including under-21s and apprentices.”

Financial services firms compile these statutory rates into accessible reference tables, though primary authority rests with government publications.
What should you check before your next payslip?
Verify your tax code reflects current rates, particularly if your employer implemented January 2024 changes mid-year. Self-employed individuals should ensure their payments on account align with the new 8% Class 4 rate rather than previous percentages.

Frequently asked questions
How much National Insurance do I pay on a £30,000 salary?
A £30,000 annual salary—approximately £577 weekly—incurs 8% on the £335 portion above the £242 threshold. This generates roughly £26 weekly or £1,352 annually, though exact figures depend on weekly distribution and any bonus payments.
What is the difference between Class 2 and Class 4?
Class 2 requires a flat £3.45 weekly payment for profits above £6,725. Class 4 charges 8% on profits between £6,396 and £50,270, plus 2% above that. Most self-employed individuals pay both classes simultaneously.
Do employers pay National Insurance on pensions?
Employer pension contributions do not attract National Insurance liability. This creates an incentive for salary sacrifice arrangements where employees exchange salary for pension contributions, reducing NICs for both parties.
Can I check my National Insurance record online?
HMRC’s online service allows verification of contribution history, showing years of full contributions, gaps, and projected state pension entitlement. This requires a Government Gateway account.
What happens if I pay too much National Insurance?
Overpayments typically arise from multiple employments exceeding the Upper Earnings Limit separately. HMRC usually reconciles these automatically after the tax year ends, issuing refunds directly to taxpayers or adjusting tax codes.
Are National Insurance rates the same across the UK?
National Insurance rates apply uniformly across England, Scotland, Wales, and Northern Ireland. Unlike income tax, which varies by devolved administration, NICs remain reserved to Westminster and consistent nationally.
How do I calculate weekly earnings from monthly pay?
Multiply monthly gross pay by 12, then divide by 52. Alternatively, HMRC recognizes the direct monthly equivalent thresholds (£1,048 for primary, £4,189 for upper) for monthly payroll processing.
