National Insurance Rates 2025-26: Employee & Employer Contributions

Complete guide to National Insurance rates for 2025-26, covering Class 1 employee and employer contributions, and Class 4 for self-employed people.

Employee National Insurance (Class 1) — 2025-26

Employees pay Class 1 National Insurance contributions on their earnings. NI is separate from income tax and is calculated on gross pay before pension deductions.

BandAnnual EarningsWeekly EarningsRate
Below Primary ThresholdUp to £12,570Up to £2420%
Main rate£12,570 to £50,270£242 to £9678%
Above Upper Earnings LimitAbove £50,270Above £9672%

The Primary Threshold (£12,570) was aligned with the Personal Allowance in 2022 and has been frozen at this level since.

Employer National Insurance (Class 1 Secondary) — 2025-26

Employers pay a separate NI contribution on top of employee pay. The employer NI rate and threshold changed significantly in April 2025.

ThresholdAnnual EarningsRate
Below Secondary ThresholdUp to £5,0000%
Above Secondary ThresholdAbove £5,00015%

Key changes from April 2025:

  • The employer NI rate increased from 13.8% to 15%
  • The Secondary Threshold fell from £9,100 to £5,000
  • The Employment Allowance increased from £5,000 to £10,500 per year (for eligible employers)

These changes mean that for a typical employee earning £30,000, the employer's annual NI bill increased by approximately £900.

Self-Employed National Insurance — Class 2 & Class 4

Self-employed people pay different classes of NI than employees.

ClassProfitsRateNotes
Class 2Above £12,570Voluntary / £3.45/week equivalentTreated as paid via Self Assessment if profits above £12,570; relevant for State Pension entitlement
Class 4 — main rate£12,570 to £50,2706%Paid via Self Assessment
Class 4 — upper rateAbove £50,2702%Paid via Self Assessment

From 2024-25 onwards, Class 2 NI for most self-employed people with profits above the Small Profits Threshold is treated as paid automatically — it no longer needs to be paid separately but continues to count towards State Pension and benefits entitlement. Those with profits below £12,570 may make voluntary Class 2 contributions (£3.45 per week) to protect their NI record.

Worked Examples

Example 1: Employee earning £30,000

Annual employee NI on a £30,000 salary:

  • Earnings below £12,570: £0 NI
  • Earnings from £12,570 to £30,000 = £17,430 × 8% = £1,394.40
  • Total employee NI: approximately £1,394 per year (£116/month)

Employer NI on the same salary: (£30,000 − £5,000) × 15% = £25,000 × 15% = £3,750 per year

Example 2: Employee earning £60,000

Annual employee NI on a £60,000 salary:

  • Main rate band: (£50,270 − £12,570) × 8% = £37,700 × 8% = £3,016
  • Above UEL: (£60,000 − £50,270) × 2% = £9,730 × 2% = £194.60
  • Total employee NI: approximately £3,211 per year (£268/month)

Employer NI: (£60,000 − £5,000) × 15% = £55,000 × 15% = £8,250 per year

See full breakdown: £60,000 after tax

Example 3: Self-employed with £40,000 profit

Class 4 NI on £40,000 self-employed profit:

  • Profits from £12,570 to £40,000 = £27,430 × 6% = £1,645.80
  • Total Class 4 NI: approximately £1,646 per year

National Insurance and the State Pension

You need 35 qualifying years of NI contributions to receive the full new State Pension (£221.20 per week in 2025-26). You need at least 10 qualifying years to receive any State Pension. A qualifying year is a tax year in which you have paid, or been credited with, enough NI contributions.

NI contributions also count towards other benefits including Maternity Allowance, Statutory Sick Pay, and contribution-based Employment and Support Allowance.
