What is Salary Sacrifice?
Salary sacrifice, also known as salary exchange, is a contractual agreement between employers and employees where the employee agrees to reduce their gross salary in exchange for non-cash benefits. 77% of UK organisations currently use salary sacrifice arrangements, with adoption rates varying across industry sectors. The salary reduction occurs before tax and National Insurance contributions (NICs) are calculated, creating tax savings for both parties.
With employer National Insurance contributions rising to 15% from April 2025 (up from 13.8%), salary sacrifice schemes have become increasingly attractive for employers seeking to offset rising payroll costs while providing valuable employee benefits. According to recent research, 34% of UK employers are already using salary sacrifice schemes to manage costs and support employee wellbeing.
How Salary Sacrifice Works in 2025
The process remains straightforward but with enhanced financial benefits due to recent tax changes:
Step 1: Contractual Agreement
You and your employee agree on the salary sacrifice arrangement, including:
- Type of benefit to be provided
- Amount of salary to be sacrificed
- Duration of the arrangement
- Terms for changes or opt-out provisions
Step 2: Salary Reduction
The agreed amount is deducted from the employee's gross salary before tax and National Insurance calculations. Critically, this reduction cannot take the employee's earnings below the National Minimum Wage (£12.21 per hour for employees over 21 from April 2025).
Step 3: Benefit Provision
You provide the agreed non-cash benefit, which could involve:
- Facilitating access to schemes (Cycle to Work, electric vehicles)
- Direct provision (pension contributions, childcare support)
- Third-party arrangements (technology schemes, healthcare benefits)
Financial Impact Example
Employee earning £50,000 annually sacrificing £3,000 for pension:
- Employee saves: £600 in income tax + £360 in NIC = £960 annually
- Employer saves: £450 in NIC (15% rate from 2025)
- Total system savings: £1,410 per employee per year
Popular Salary Sacrifice Schemes in 2025
1. Pension Contributions - The Most Beneficial Option
Pension salary sacrifice remains the most popular and beneficial form of salary sacrifice scheme:
Key Statistics:
- Pension salary sacrifice can save employers £345 annually per employee earning £50,000
- Across a workforce of 250 employees, this adds up to £86,250 in annual savings
- 63% of employers choose to retain NIC savings rather than pass them to employees' pension contributions
How It Works: Employees sacrifice part of their salary, and employers pay the equivalent amount directly into the employee's pension pot. This creates significant tax efficiencies while boosting retirement savings.
2. Electric Vehicle (EV) Schemes - High-Value Savings
Electric vehicle salary sacrifice schemes offer substantial benefits due to government policy supporting EV adoption:
2025 Benefits:
- Benefit-in-Kind (BiK) rate: Just 3% for 2025-26 (compared to 25-37% for petrol/diesel vehicles)
- Average annual NI savings: £56,000 per participating business
- Vehicle Excise Duty: £10 for first year (introduced April 2025)
- High-value exchanges: Generate significant salary sacrifice amounts
Tax Advantages: Unlike other benefits, HMRC requires using the BiK value for EVs even if lower than salary sacrificed, creating deliberate tax incentives for greener transport.
3. Cycle-to-Work Schemes - Popular and Simple
Government-backed bicycle and cycling safety equipment schemes remain highly popular:
Benefits:
- No tax or NIC liability for qualifying cycling equipment
- Simple administration with established providers
- Popular with environmentally conscious employees
- Supports employee health and wellbeing initiatives
4. Technology Schemes - Essential Modern Benefits
Employee access to laptops, mobile phones, and technology equipment through salary sacrifice:
Advantages:
- Helps employees access necessary work technology
- Often provides access to business-rate pricing
- Supports remote and hybrid working arrangements
- Typically 2-4 year arrangements with ownership transfer options
5. Holiday Trading - Significant Uptake and Savings
Additional holiday purchase schemes show strong employee engagement:
Performance Data:
- Average savings: Over £130,000 per employer annually
- Uptake rates: 21-46% across different business sizes
- Infrastructure services company example: 46% uptake rate with 2,000 employees
- Small business example: 21% uptake with 75 employees saving over £21,000 annually
The 2025 Business Case for Salary Sacrifice
Offsetting National Insurance Increases
The April 2025 increase in employer NIC from 13.8% to 15% creates significant cost pressures:
Financial Impact:
- Company with 500 employees earning average £40,000: Additional £60,000 annual NIC costs
- Salary sacrifice schemes directly reduce these costs by lowering gross payroll subject to NIC
- Strategic implementation can offset substantial portions of NIC increases
Government Research Findings: Recent HMRC research highlighted that proposed pension salary sacrifice changes could cost employees up to £560 annually and employers £241 based on a £35,000 salary, underscoring the current value of these arrangements.
Employee Retention and Recruitment Benefits
Research-Backed Benefits:
- Many employers report positive impact on employee retention through salary sacrifice arrangements

Salary sacrifice schemes represent a significant opportunity for UK employers in 2025, particularly given the increase in employer National Insurance contributions to 15%. With 77% of organisations already using these arrangements and clear evidence of substantial financial benefits, the question is not whether to implement salary sacrifice, but how quickly and comprehensively you can do so.
The data is compelling: employers can save £345 annually per £50,000 employee through pension salary sacrifice alone, while comprehensive schemes including holiday trading average over £130,000 in annual savings per employer. These figures become even more attractive when considering that only 34% of employers currently use salary sacrifice schemes comprehensively, providing early adopters with competitive advantages in both cost management and employee attraction.
Success requires strategic thinking beyond simple cost savings. The most effective implementations combine multiple benefit types, maintain strong employee communication, and integrate schemes seamlessly with existing HR and payroll systems. With proper planning and execution, salary sacrifice schemes deliver the rare business outcome of reduced costs alongside enhanced employee benefits and satisfaction.
As regulatory pressures increase and competition for talent intensifies, salary sacrifice schemes offer a proven, government-supported method to optimize employment costs while demonstrating genuine commitment to employee financial wellbeing. The time to act is now, while regulatory advantages remain stable and competitive differentiation opportunities exist.
For employers serious about controlling costs while enhancing their employee value proposition, comprehensive salary sacrifice implementation isn't just an option—it's a strategic imperative for sustainable business growth in 2025 and beyond.
Frequently Asked Questions
How much can employees save through salary sacrifice? Savings depend on tax bracket and scheme type. A basic rate taxpayer sacrificing £1,000 saves 20% income tax plus 12% NIC (£320 total), while employers save 15% NIC (£150). Higher rate taxpayers save 40% income tax plus 2% NIC on amounts over £50,270.
What is the maximum amount employees can sacrifice? There's no specific legal limit, but practical constraints include: maintaining National Minimum Wage compliance (£12.21/hour for over-21s), scheme-specific limits (e.g., pension annual allowances), and impact on statutory benefits like maternity pay calculated on reduced earnings.
How does the 2025 NIC increase affect salary sacrifice benefits? The increase from 13.8% to 15% makes salary sacrifice more attractive by increasing employer savings. For example, employer NIC savings on a £3,000 salary sacrifice increased from £414 to £450 annually, while the additional 1.2% makes the schemes more cost-effective for employers.
Which salary sacrifice schemes offer the highest returns? Pension schemes typically offer the highest returns due to tax relief and NIC savings on both sides. Electric vehicle schemes provide high-value exchanges with low BiK rates (3% in 2025-26). Holiday trading shows strong uptake with average savings over £130,000 per employer annually.
Do salary sacrifice schemes affect mortgage applications? Yes, lenders typically assess affordability based on reduced salary after sacrifice. However, some lenders consider the total package including benefits. Employees should check with potential lenders before entering significant salary sacrifice arrangements.
How do salary sacrifice schemes affect statutory benefits? Statutory benefits like Maternity Pay, Sick Pay, and State Pension contributions are calculated on reduced salary, potentially lowering entitlements. Employees should understand these implications, particularly those planning families or approaching retirement age.
What administrative burden do salary sacrifice schemes create? Most employers find schemes straightforward once established. Initial setup requires legal documentation and payroll integration, but ongoing administration is typically minimal. Annual agreement renewals and employee communication represent the main ongoing tasks.
