April 2025 employer NIC increase is the UK's largest employment tax rise in a generation
From April 2025, employer NIC rose from 13,8% to 15% and the secondary threshold (below which no employer NIC is paid) dropped from £9.100 to £5.000/year. For a worker earning £30.000, annual employer NIC cost increased from approximately £2.888 to £3.750 — a £862 increase. For minimum wage workers at £22.000, employer NIC increased from approximately £1.773 to £2.550 — a £777 increase. The OBR estimated this raises approximately £25 billion annually but significantly increased business labour costs.

Employee NIC was reduced from 12% to 8% in two cuts in 2024 — partially offsetting fiscal drag
Employee NIC was cut from 12% to 10% in January 2024 and to 8% in April 2024. This reduced the employee burden on the £12.570–£50.270 band. At £35.000, the NIC reduction saves approximately £700/year versus the pre-2024 position. However, the frozen income tax thresholds have more than offset this saving for most workers — the net effect of 2021-2026 changes is a real tax increase for most employees despite the NIC headline reduction.

Self-employed NIC reform: Class 2 abolished from April 2024 — Class 4 now the only self-employed NIC
Class 2 NIC (flat £3.45/week for self-employed) was abolished from April 2024. Self-employed workers now pay only Class 4 NIC: 6% on profits £12.570–£50.270 and 2% above. This simplified self-employed NIC but slightly increased the cost for low-profit self-employed who previously paid only Class 2. State pension entitlement for self-employed now comes through Class 4 credits rather than Class 2.

ⓘ Primary Threshold (£12.570) aligned with Personal Allowance since 2022 — simplifying calculation. Upper Earnings Limit (£50.270) aligned with Higher Rate income tax threshold. Employee NIC reduced from 12% to 8% in 2024 — but frozen thresholds mean more income is now NIC-able.

| £100.000 | £4.011 | £14.250 | £18.261 | 18,3% | £114.250 |
ⓘ True employer cost = gross salary + employer NIC. For a £30.000 salary, the employer actually spends £33.750 — £3.750 goes to HMRC as employer NIC. For £100.000, the employer spends £114.250. Total NIC as a percentage of gross is highest at around £40.000-£60.000 where the main employee rate (8%) and employer rate (15%) both apply fully.

| Class | Who Pays | Rate | On What | Annual Max |
|---|---|---|---|---|
| Class 4 Main | Self-employed with profits above £12.570 | 6% | Profits £12.570 – £50.270 | Max £2.257 |
| Class 4 Upper | Self-employed with profits above £50.270 | 2% | All profits above £50.270 | Uncapped |
| Class 3 Voluntary | Anyone with gaps in NI record | £17,45/week | Voluntary flat payment | Max £907/year — fills gaps |
| Class 2 (abolished) | Self-employed | Abolished April 2024 | — | — |
ⓘ Class 3 NIC is used to fill gaps in NI contribution record — needed to qualify for full state pension (35 qualifying years required). A qualifying year costs £17,45/week × 52 = £907. For workers with NI gaps, buying qualifying years is often extremely cost-effective — a single qualifying year increases state pension by approximately £328/year for life.

🔬 Methodology & Sources
UK NIC Calculation
National Insurance Contributions (NIC) fund UK state benefits including state pension, jobseeker's allowance, maternity pay, sick pay, and bereavement benefits. Class 1 is paid by employed workers and their employers. Class 4 by self-employed. Class 3 is voluntary. Employee NIC is calculated weekly/monthly — not annually — which can produce different results for variable earners vs annual calculation. Employer NIC has no upper earnings limit.
Formula
Employee_NIC = (min(Annual_Gross, UEL) − PT) × 0.08 + max(0, Annual_Gross − UEL) × 0.02 | Employer_NIC = max(0, Annual_Gross − 5000) × 0.15

❓ Frequently Asked Questions
Employee Class 1 NIC: 8% on annual earnings £12.570–£50.270; 2% above £50.270 (no ceiling). Employer Class 1 NIC: 15% on earnings above £5.000 secondary threshold (no ceiling). Self-employed Class 4: 6% on profits £12.570–£50.270; 2% above. Class 2 was abolished in April 2024. At £35.000, employee NIC is approximately £1.798/year; employer NIC approximately £4.500.
The October 2024 Budget (Chancellor Rachel Reeves) increased employer NIC from 13,8% to 15% and reduced the secondary threshold from £9.100 to £5.000 per year, effective April 2025. This raised employer NIC costs by approximately £600-£900 per worker at typical salaries. The measure was designed to raise approximately £25 billion annually to fund public services. It was highly controversial — particularly among small businesses and hospitality — with critics arguing it would slow hiring and reduce wages.
You need 35 qualifying years of National Insurance contributions to receive the full new State Pension (£221,20/week in 2026/27). You need at least 10 qualifying years to receive any state pension. Qualifying years come from Class 1 (employed), Class 4 (self-employed), Class 3 (voluntary), or credits (unemployment, parenting, disability). Workers with gaps can buy additional qualifying years at £17,45/week (£907/year) — buying a year increases state pension by approximately £328/year for life.
No employee NIC is paid below the Primary Threshold (£12.570/year). However, earnings between £6.396 (Lower Earnings Limit) and £12.570 earn qualifying National Insurance credits — counting toward state pension and benefits without any NIC payment. Workers earning below £6.396 get no NI credits. Employer NIC applies from £5.000 — employers of very low-paid workers (below £5.000) pay no employer NIC, but this threshold is per employment, not per worker.
UK employee NIC (8%/2%) is lower than most European equivalents. Germany: approximately 20%; France: approximately 23%; Belgium: 13,07%; Netherlands: approximately 27,6%; Austria: 17,9%. However, UK employer NIC (15%) is comparable to or above most peers. Total combined UK NIC (employee + employer = approximately 23%) is lower than France (68%), Belgium (40%), Germany (40%), but higher than Ireland (15%) and Switzerland (16%).
