How the Salary Sacrifice Electric Car Scheme Works
A salary sacrifice scheme for electric cars is an employee benefit arrangement where you agree to exchange part of your gross salary for an electric vehicle lease. The monthly lease payment is deducted from your salary before income tax and National Insurance contributions are calculated, resulting in significant tax savings.
Key Benefits
- Lower monthly costs compared to personal leasing due to tax savings
- Reduced income tax and National Insurance contributions
- Low Benefit in Kind taxation for electric vehicles
- All-inclusive package typically covering insurance, maintenance, and breakdown cover
- Access to newer electric vehicles without large upfront costs
- Environmentally friendly transport option
What’s Included
Most salary sacrifice electric car schemes include a comprehensive package covering vehicle lease, road tax, manufacturer warranty, breakdown assistance, routine maintenance, and fully comprehensive insurance. You typically only pay for the electricity to charge the vehicle and the Benefit in Kind tax.
Important: The current BiK rate for fully electric vehicles is exceptionally low at 2-3%, making this the optimal time to participate in a salary sacrifice scheme. Rates are scheduled to increase gradually to 5% by 2027/28.
Tax Band Comparison
Your tax savings through salary sacrifice depend significantly on your income tax band. Higher earners benefit more from the scheme due to greater tax relief on the sacrificed salary amount.
| Tax Band | Income Range | Income Tax Rate | NI Rate (Primary) |
|---|---|---|---|
| Basic Rate | £12,571 – £50,270 | 20% | 8% |
| Higher Rate | £50,271 – £125,140 | 40% | 2% |
| Additional Rate | Over £125,140 | 45% | 2% |
National Insurance contributions are deducted on the sacrificed amount, providing additional savings. Basic rate taxpayers pay 8% NI up to the upper earnings limit, whilst higher and additional rate taxpayers pay 2% NI on earnings above this threshold.
Benefit in Kind Tax Explained
When you receive an electric car through salary sacrifice, it’s treated as a company car benefit. You must pay Benefit in Kind tax on this benefit, calculated based on the car’s P11D value, the BiK percentage rate, and your income tax band.
BiK Calculation Formula
Annual BiK Tax = P11D Value × BiK Rate × Your Income Tax Rate
Monthly BiK Tax = Annual BiK Tax ÷ 12
Electric Vehicle BiK Rates
| Tax Year | BiK Rate |
|---|---|
| 2024/25 | 2% |
| 2025/26 | 3% |
| 2026/27 | 4% |
| 2027/28 | 5% |
Electric vehicles enjoy substantially lower BiK rates compared to petrol or diesel vehicles, which can have BiK rates exceeding 30%. This makes electric car salary sacrifice schemes particularly attractive from a tax perspective.
Real-World Example
Consider an employee earning £45,000 annually who wants to lease an electric car worth £35,000 with a monthly lease cost of £500.
Without Salary Sacrifice
Personal lease monthly cost: £500
With Salary Sacrifice (Basic Rate Taxpayer)
- Monthly lease deduction: £500
- Income tax saving: £100 (£500 × 20%)
- National Insurance saving: £40 (£500 × 8%)
- BiK tax cost: £58 (£35,000 × 2% × 20% ÷ 12)
- Net monthly cost: £418
- Total monthly saving: £82
This represents an annual saving of £984, making the electric car significantly more affordable whilst also including insurance, maintenance, and other benefits not typically covered in a standard personal lease.
Remember: Salary sacrifice reduces your gross salary, which may affect other benefits calculated on gross salary, such as pension contributions, life insurance, or mortgage applications. Consider these implications before committing to a scheme.
Eligibility and Considerations
Not all employers offer salary sacrifice schemes, so check with your HR department first. If available, consider the following factors before participating:
Eligibility Requirements
- Your employer must offer an electric car salary sacrifice scheme
- You must earn above the National Minimum Wage after the salary sacrifice
- You typically need to commit to a lease period of 2-4 years
- You must be a permanent employee with a suitable employment contract
Key Considerations
- Impact on other salary-linked benefits such as pension contributions and life insurance
- Effect on borrowing capacity for mortgages or loans based on gross salary
- Early termination fees if you leave employment before the lease ends
- Potential excess mileage charges if you exceed the agreed annual mileage
- Your responsibility to return the car in good condition at lease end
Step-by-Step Guide
1. Check Employer Participation
Contact your HR department to confirm whether your employer offers a salary sacrifice scheme for electric vehicles. Ask about approved providers and available vehicle options.
2. Review Available Vehicles
Examine the range of electric vehicles available through the scheme. Consider factors such as range, size, features, and suitability for your daily commute and lifestyle needs.
3. Calculate Your Savings
Use calculators like this one to work out your potential monthly savings and net cost. Compare this to personal lease or purchase options to confirm the financial benefit.
4. Consider the Implications
Evaluate how the salary reduction will affect your take-home pay, pension contributions, and other benefits. Verify you’ll still meet National Minimum Wage requirements after the sacrifice.
5. Apply Through Your Employer
Complete the application process through your employer’s chosen scheme provider. You’ll need to select your vehicle, agree to the lease terms, and sign an amended employment contract reflecting the salary sacrifice.
6. Await Delivery
Once approved, your chosen electric vehicle will be ordered and delivered. The salary sacrifice deductions will begin as specified in your contract, typically when you receive the vehicle.
