Key Insights

• Electric car salary sacrifice schemes offer the highest potential savings in 2025, with employees saving 20-50% on new EVs thanks to the low 3% Benefit-in-Kind rate, compared to up to 37% for petrol cars.
• Pension salary sacrifice provides guaranteed long-term benefits for retirement planning, offering immediate tax and National Insurance savings while building future financial security.
• Higher-rate taxpayers benefit most from salary sacrifice schemes, with potential savings of up to 42% (40% income tax + 2% National Insurance) on tax-exempt benefits like pensions and EVs.
• Multiple salary sacrifice schemes can be combined to maximise tax efficiency, allowing employees to simultaneously benefit from pension contributions, EV leasing, and other workplace benefits.

Salary sacrifice schemes continue to offer UK employees one of the most effective ways to reduce their tax burden while accessing valuable benefits. But with multiple options available – from electric car salary sacrifice to pension schemes – is salary sacrifice worth it in 2025, and which type offers the best value?

What Is Salary Sacrifice?

Salary sacrifice, also known as salary exchange, is a formal arrangement where you agree to reduce your gross salary in exchange for non-cash benefits provided by your employer. This arrangement reduces your taxable income, resulting in lower Income Tax and National Insurance contributions while maintaining access to valuable benefits.

The key advantage is simple: you receive the same benefit but pay less tax to access it, effectively increasing your take-home pay or the value you receive from your total compensation package.

How Salary Sacrifice Works

Think of salary sacrifice as changing the order of operations for your pay:

Traditional method: Receive full salary → Pay tax and National Insurance → Use remaining income for benefits

Salary sacrifice method: Reduce salary by benefit cost → Pay tax on reduced amount → Receive benefit

This seemingly simple change can result in significant savings, particularly when combined with tax-efficient benefits like electric car schemes or pension contributions.

Electric Car Salary Sacrifice: The Most Tax-Efficient Option

Why EVs Lead in 2025

Electric car salary sacrifice has emerged as one of the most attractive salary sacrifice options available. With the Benefit-in-Kind rate for electric vehicles set at just 3% for 2025/26, employees can access premium electric cars at a fraction of their normal cost.

Real Savings Example

Consider an employee earning £45,000 annually choosing a £500 monthly electric car through The Electric Car Scheme:

Without salary sacrifice:

• Monthly car cost: £500 (after tax)

• Actual cost from salary: £625+ (depending on tax rate)

With EV salary sacrifice:

• Monthly salary reduction: £500

• Net cost from take-home pay: £325-£350

• Monthly saving: £275-£300

This represents a 40-50% reduction in the real cost of accessing a new electric vehicle, making premium EVs affordable for a much wider range of employees.

Additional EV Benefits

Beyond the immediate tax savings, electric car salary sacrifice schemes often include:

• Full maintenance and servicing

• Insurance coverage

• Breakdown assistance

• EV charging solutions

• Road tax (when applicable)

Combined with lower running costs – charging an EV costs significantly less than petrol – the total cost of ownership becomes extremely competitive.

Pension Salary Sacrifice: Building Long-term Wealth

The Pension Advantage

Pension salary sacrifice remains the most common and widely available salary sacrifice option. Unlike other benefits, pension contributions offer both immediate tax relief and long-term wealth building.

Pension Savings Calculation

For an employee earning £50,000 with a 8% total pension contribution (5% employee, 3% employer):

Standard pension:

• Employee contribution: £2,500 (after basic rate tax relief)

• Employer contribution: £1,500

• Total pension pot growth: £4,000

Pension salary sacrifice:

• Employee net cost: £2,000 (saving £500 in tax and NI)

• Employer contribution: £4,000 (full amount)

• Additional annual saving: £500

Long-term Impact

The combination of immediate savings and compound growth makes pension salary sacrifice particularly powerful for younger employees. A 25-year-old saving an additional £500 annually through salary sacrifice could see their pension pot increase by over £50,000 by retirement.

Comparing Salary Sacrifice Options

Tax Efficiency Rankings

1. Electric vehicles (3% BiK rate) - Highest immediate savings

2. Pension contributions (tax-exempt) - Long-term wealth building

3. Cycle-to-work schemes (tax-exempt) - Moderate savings on transport

4. Childcare vouchers (if existing scheme) - Valuable for eligible families

5. Technology schemes (taxable benefit) - Lower savings due to BiK tax

Income Level Considerations

Lower-rate taxpayers (20% tax bracket):

• EV salary sacrifice: Up to 28% savings (20% tax + 8% NI)

• Pension sacrifice: 28% immediate relief plus long-term growth

Higher-rate taxpayers (40% tax bracket):

• EV salary sacrifice: Up to 42% savings (40% tax + 2% NI)

• Pension sacrifice: 42% immediate relief plus avoiding higher-rate tax

Additional rate taxpayers (45% tax bracket):

• Maximum benefit from all salary sacrifice schemes

• Potential to reduce taxable income below higher thresholds

Who Benefits Most from Salary Sacrifice?

Ideal Candidates

Salary sacrifice works best for employees who:

• Earn above £20,000 annually (ensuring sufficient headroom above minimum wage)

• Pay Income Tax and National Insurance

• Have stable employment

• Want to access benefits they would purchase anyway

Special Considerations

Higher earners (£100,000+): Salary sacrifice can be particularly valuable for those losing their personal allowance, as it reduces the effective 60% tax rate in the £100,000-£125,140 band.

Multiple benefit users: Employees can often combine schemes – for example, using both pension salary sacrifice and an electric car scheme simultaneously for maximum tax efficiency.

Potential Drawbacks and Limitations

Income Restrictions

Salary sacrifice cannot reduce your income below the National Minimum Wage. For employees on lower salaries, this may limit the benefits they can access through salary sacrifice.

Impact on Salary-linked Benefits

Some salary-related calculations may be affected:

• Mortgage applications: Most lenders understand salary sacrifice, but some may require clarification

• Life insurance: Usually based on pre-sacrifice salary

• Redundancy pay: May be calculated on reduced salary

• Statutory payments: Based on reduced salary for maternity/paternity pay

Commitment Periods

Different schemes have varying commitment levels:

• Pension sacrifice: Usually flexible with monthly changes

• Electric car schemes: Typically 2-4 year commitments

• Technology schemes: Often 12-month minimum terms

Maximising Your Salary Sacrifice Benefits

Strategic Combinations

Consider combining multiple schemes for maximum efficiency:

1. Core pension contributions for long-term security

2. Electric car scheme for immediate transport savings

3. Additional pension top-ups if higher-rate taxpayer

4. Cycle-to-work scheme for secondary transport

Timing Considerations

Year-end planning: Higher-rate taxpayers can use salary sacrifice to reduce their taxable income below key thresholds, maintaining eligibility for benefits like Child Benefit.

Bonus sacrifice: Converting bonuses to pension contributions through salary sacrifice can be particularly tax-efficient, avoiding both Income Tax and National Insurance on the full amount.

2025 Tax Changes and Implications

Electric Vehicle BiK Rates

The Benefit-in-Kind rate for electric vehicles remains extremely competitive:

• 2025/26: 3%

• 2026/27: 4%

• 2027/28: 5%

Even with gradual increases, EVs maintain significant advantages over petrol and diesel vehicles (which can attract BiK rates up to 37%).

National Insurance Changes

Recent changes to National Insurance have maintained the effectiveness of salary sacrifice schemes, with employers continuing to benefit from reduced NI contributions on salary sacrifice arrangements.

Electric car salary sacrifice currently offers the highest immediate savings, with employees typically saving 20-50% compared to personal leasing or purchasing. With the 3% Benefit-in-Kind rate and comprehensive scheme benefits, EV schemes represent exceptional value.

Pension salary sacrifice provides essential long-term benefits, offering both immediate tax relief and crucial retirement planning advantages that compound over time.

For many employees, the optimal approach involves combining multiple salary sacrifice schemes to maximise both immediate savings and long-term financial security.
