Key takeaway: The Benefit in Kind (BiK) rate for pure electric company cars is 4% for 2026/27 — rising by just 1% per year to a capped 9% by 2030. Combined with salary sacrifice, this makes an electric vehicle one of the most tax-efficient benefits an employer can offer: employees save 20–50% on the real cost of an EV, and employers save National Insurance Contributions on the sacrificed salary. Payroll bureaus and practices advising employer clients are seeing growing demand for EV scheme guidance — and BrightPay is built to handle the payroll administration correctly.
Few employee benefits have attracted as much commercial interest in recent years as electric vehicle salary sacrifice. The combination of a very low Benefit in Kind rate — deliberately set to encourage EV adoption — with the NIC and income tax savings from salary sacrifice creates a genuine financial incentive for both employees and employers. For employers facing pressure on recruitment and retention budgets, the EV scheme offers a meaningful enhancement to the total reward package at a cost that is significantly lower than an equivalent cash pay rise.
For payroll bureaus, the demand from employer clients to set up and administer EV salary sacrifice schemes is increasing. Getting the payroll treatment right — calculating the BiK charge accurately, deducting the correct salary sacrifice amount, ensuring the P11D or payrolled benefit is reported correctly — requires understanding how the scheme works and how the payroll system handles it.
How EV Salary Sacrifice Works
In an EV salary sacrifice scheme, an employee agrees to give up a portion of their gross salary in exchange for the use of an electric vehicle provided by the employer. The employer leases the vehicle and provides it to the employee as a company car benefit. The employee’s salary is reduced by the monthly lease cost, and the employer pays for the car from that reduction.
Because the salary reduction is made before income tax and NIC, both the employee and the employer pay less. The employee receives a car with an effective monthly cost significantly lower than they could achieve through a personal lease — because they are paying from pre-tax income rather than net pay. The employer’s NIC liability reduces on the sacrificed salary amount.
The Benefit in Kind charge on the electric car is the mechanism by which the employee is taxed on the value of the benefit they receive. At 4% of the car’s list price (including accessories) for 2026/27, the BiK charge is very low compared to petrol or diesel vehicles, where BiK rates range from 25% to over 37% depending on emissions. For an EV with a list price of £40,000, the annual BiK value is £1,600 — producing an income tax charge of £320 for a basic rate taxpayer, or £640 for a higher rate taxpayer. The NIC and income tax saving on the sacrificed salary typically more than offsets this, producing a net financial benefit for the employee.
The Employer NIC Saving
For employers, the NIC saving from salary sacrifice is the primary financial benefit. Employer NIC at 15% applies to the sacrificed salary amount. For an employer with 20 employees each sacrificing £500 per month, the annual NIC saving is approximately £18,000. For larger schemes, the saving can fund a portion of the employer’s fleet management cost.
Importantly, the minimum wage interaction must be checked for all salary sacrifice schemes. Post-sacrifice pay must remain at or above the relevant National Minimum Wage rate — a requirement that limits the availability of EV salary sacrifice to employees earning sufficiently above the NMW floor. For lower-paid employees, the scheme may need to be structured differently or excluded.
The employer must also ensure that the contract of employment is appropriately amended for the duration of the salary sacrifice arrangement, and that the arrangement is properly documented. Informal arrangements that are not reflected in employment contracts can create employment law and tax compliance risk.
The BiK Rate Roadmap to 2030
One of the most commercially useful features of the current EV BiK regime is the certainty it provides. HMRC has published the BiK rates for pure electric cars through to 2029/30:
- 2026/27: 4%
- 2027/28: 5%
- 2028/29: 7%
- 2029/30: 9%
This predictable, gradual increase allows employees and employers to model the cost of the scheme over the car’s lease period with confidence. A three-year lease starting in April 2026 will have a known BiK rate for each year of the arrangement. By comparison, petrol and diesel BiK rates face potential increases as the government pursues its decarbonisation agenda, making conventional company car schemes increasingly expensive.
How BrightPay Handles EV Salary Sacrifice
BrightPay manages the payroll components of an EV salary sacrifice scheme across the full employee lifecycle within the arrangement. The key payroll functions are:
Salary sacrifice deduction. BrightPay applies the salary sacrifice reduction to the employee’s gross pay each period — before the calculation of income tax and NIC. This ensures the tax and NIC saving is correctly reflected on every payslip and that the employee’s PAYE position is accurate.
NMW compliance check. BrightPay automatically flags where a salary sacrifice deduction would take an employee’s effective hourly rate below the applicable NMW — protecting the employer from an inadvertent NMW breach and alerting the bureau to review the arrangement for that employee.
BiK reporting. The electric car BiK can be processed either via the traditional P11D route at year end or through payrolling of benefits, where the BiK value is added to the employee’s taxable pay each period and PAYE collected in real time. BrightPay supports both approaches. For employers using payrolled benefits — which is becoming increasingly standard and will be mandatory from April 2027 for most benefits — BrightPay adds the BiK value to the payroll calculation each period, ensuring the correct tax is deducted and eliminating the year-end P11D.
RTI submissions. All salary sacrifice deductions and payrolled BiK values are reflected in the Real Time Information Full Payment Submission, ensuring HMRC has accurate data for each employee throughout the year.
What Practices Should Advise Employer Clients
For employers considering an EV salary sacrifice scheme for the first time, the advice from their accountant or payroll bureau should cover: the NMW check for all participating employees; the employment contract amendment requirement; the choice between P11D and payrolled benefits reporting; the fleet management and insurance implications; and whether the employer wants to restrict the scheme to certain vehicle types or price bands.
For bureaus already running payrolls for clients with EV schemes, a review of whether the BiK is being processed through payrolled benefits or P11D — and whether the employer has registered for payrolled benefits with HMRC — is the immediate compliance check.
Frequently Asked Questions
What is the BiK rate for a pure electric car in 2026/27?
The Benefit in Kind rate for a pure zero-emission electric car is 4% of the vehicle’s list price for 2026/27. This rises by 1% in 2027/28 (5%), then by 2% in each of 2028/29 (7%) and 2029/30 (9%). The rate is confirmed to 2030, providing certainty for multi-year lease arrangements.
How does salary sacrifice reduce the cost of an electric car for an employee?
Under a salary sacrifice scheme, the employee gives up gross salary equal to the monthly lease cost of the vehicle. Because the sacrifice is made before income tax and NIC, the employee pays less tax on their income. The BiK charge on the car is very low (4% of list price), so the combined cost — net pay reduction plus BiK tax — is typically significantly less than the retail lease cost the employee would pay from their net salary.
Does salary sacrifice for an EV affect the employee’s state pension or other benefits?
Salary sacrifice reduces the employee’s contractual pay, which can affect state pension entitlement (if post-sacrifice pay falls below the Lower Earnings Limit), statutory payments based on normal weekly earnings, and any income-assessed benefits. For most employees earning above the NMW floor, the impact on state pension is negligible — but practices should flag the issue for employees close to the Lower Earnings Limit.
What is the minimum wage risk with EV salary sacrifice?
Post-sacrifice pay must remain at or above the relevant NMW rate for each worker’s age band. If the salary sacrifice would take an employee below the NMW floor, the scheme cannot be applied at that level. BrightPay flags this check automatically, but bureaus should review all participating employees — particularly following NMW rate increases — to ensure ongoing compliance.
What is the difference between a P11D and payrolled benefits for an EV BiK?
Under the traditional P11D route, the BiK value is reported to HMRC at the end of the tax year and the employee pays the income tax on it through a PAYE code adjustment. Under payrolled benefits, the BiK value is added to the employee’s taxable pay each period and PAYE is deducted in real time. Payrolled benefits will be mandatory for most BiKs from April 2027 — employers and bureaus should be moving to payrolled benefits now to avoid a last-minute transition.
BrightPay processes salary sacrifice EV deductions, applies the correct BiK rates, handles payrolled benefits reporting, and runs the NMW compliance check for every employee in the scheme — all within the standard payroll run. Find out more about BrightPay or speak to your account manager.
