Salary Sacrifice Explained
A comprehensive guide to salary sacrifice schemes and how they can save you money on tax and National Insurance.
What is Salary Sacrifice?
Salary sacrifice (also called salary exchange) is an arrangement where you give up part of your pre-tax salaryin exchange for a non-cash benefit from your employer. Because the benefit comes from pre-tax income, you pay less income tax and National Insurance, and your employer saves on their National Insurance contributions too.
How It Works
Benefits
- • Reduce income tax (20%, 40%, or 45%)
- • Reduce National Insurance (8% or 2%)
- • Employer saves 15% NI on sacrificed amounts (from 6 April 2025)
- • Can increase take-home pay
- • Access to benefits you might not afford otherwise
Considerations
- • Reduced official salary affects mortgage applications
- • May impact statutory payments (maternity, sick pay)
- • Can affect pension contributions based on salary
- • Lower salary could impact death-in-service benefits
- • Commitment period may apply
Tax & National Insurance Savings Explained
Employee Savings Breakdown (2025-26)
| Income Band | Income Tax | National Insurance | Total Saving |
|---|---|---|---|
| Basic rate (£12,571 - £50,270) | 20% | 8% | 28% |
| Higher rate (£50,271 - £125,140) | 40% | 2% | 42% |
| Additional rate (£125,141+) | 45% | 2% | 47% |
What This Means
For every £1,000 you sacrifice from your salary:
Employer Savings
Employers save 15% National Insurance on the sacrificed amount from 6 April 2025 (13.8% before then). Many employers share some of these savings with employees, making salary sacrifice even more attractive.
Employer saves: £750 (15% of £5,000)
Employer might contribute: £345 extra to employee's pension (50% of savings)
Pension Contributions via Salary Sacrifice
The most popular and valuable use of salary sacrifice. Instead of making pension contributions from your net salary, your employer makes them from your gross (pre-tax) salary.
Comparison: Regular vs Salary Sacrifice Pension
Regular Pension (Net Pay)
Salary Sacrifice Pension
Result
£1,400 more take-home pay per year (£117/month) for the same £5,000 pension contribution.
If employer shares 50% of their £690 NI saving: £1,745 extra (£145/month).
Important for Higher Earners
Salary sacrifice can help you stay below the £100,000 threshold where the personal allowance starts being withdrawn (60% effective tax rate on £100k-£125k income). By sacrificing salary into pension, you can keep more of your personal allowance.
Electric Cars via Salary Sacrifice
Salary sacrifice electric car schemes are increasingly popular. You sacrifice salary to "lease" an electric vehicle, and because zero-emission company cars have low Benefit in Kind (BiK) tax rates (4% for 2026-27; 3% in 2025-26; HMRC has published rates through 2029-30), the total cost can be lower than buying or leasing personally.

Health Screenings & Gym Memberships

Additional Holiday Purchase

Important Considerations & Limitations
Minimum Wage Protection
Your salary after sacrifice cannot fall below National Minimum Wage (£11.44/hour for 21+ in 2025-26). This limits salary sacrifice for lower earners.
Impact on Statutory Payments
Salary sacrifice reduces your "official" salary, which affects:
- Statutory Maternity Pay (SMP): Calculated on earnings before salary sacrifice for pensions, but after sacrifice for most other benefits
- Statutory Sick Pay (SSP): Based on reduced salary
- Life Insurance & Critical Illness: Based on reduced salary unless policy specifies otherwise
Mortgage & Loan Applications
Lenders use your official salary after sacrifice, which may reduce borrowing capacity.
Commitment Periods
Some schemes require 12-month commitments:
- Cycle to Work: Typically 12 months minimum
- Electric Cars: 2-4 year lease commitments
- Pensions: Usually flexible, can change annually
State Pension Impact
Salary sacrifice does not reduce your state pension entitlement. National Insurance credits for state pension are based on your salary before sacrifice.
