The short answer: an electric car salary sacrifice scheme can be a valuable benefit that costs the employer little or nothing. But most of the problems that do arise land on the employer, not the provider: an employee who leaves, a payroll mistake, a sacrifice that takes someone below the minimum wage. This guide sets out where schemes go wrong and how to set one up so they do not.
For the employee's side of the numbers, see our guide to what a salary sacrifice electric car costs an employee.
1. Taking pay below the minimum wage
A salary sacrifice cannot reduce an employee's cash pay below the National Minimum Wage or National Living Wage. Breaching this exposes the employer to back pay, penalties and public naming. The National Living Wage rises to £13.21 an hour from 1 April 2027, so a sacrifice that is compliant today may not be next year.
Avoid it: check every application against current and next year's rates, and build in headroom for pay rises in the minimum wage, unpaid leave and reduced hours.
2. Getting the contract variation wrong
For the tax saving to work, the employee must genuinely give up the right to part of their salary in return for the car, before that salary is earned. If the paperwork is loose, or the employee can switch back to cash at will, HMRC may treat the arrangement as ineffective.
Avoid it: use a proper written variation to the employment contract, signed before the sacrifice starts, setting out the term and what happens on change of circumstances.
3. Employees who leave
This is the most common worry, and with reason. If an employee leaves during a three or four-year agreement, someone has to deal with the car and any early termination cost. Without protection, that cost can fall on the employer.
Avoid it: choose a provider that includes early termination protection for resignation, dismissal and redundancy, and read the exclusions. Decide in advance whether any remaining cost can be recovered from the employee, and set that out clearly in the agreement and in your policies.
4. Maternity, paternity and long-term sickness
During family leave or long periods of sickness, an employee's pay may fall below the level needed to support the sacrifice, while the car stays in use. Some statutory payments are also based on average earnings, which a sacrifice can reduce.
Avoid it: agree a written policy on what happens to the sacrifice during each type of leave, check it against current guidance with your payroll adviser, and make sure employees understand it before they sign.
5. Pensions and other salary-linked benefits
If pension contributions, life cover, bonuses or overtime are calculated on contractual salary, a sacrifice can quietly reduce them. Employees are often unhappy to discover this later.
Avoid it: decide whether salary-linked benefits are based on the pre-sacrifice salary, a common approach, and say so clearly in the scheme literature.
6. The non-electric car tax trap
Electric cars work well through salary sacrifice because of their low company car tax. Cars emitting more than 75g/km of CO2 fall under the optional remuneration rules, which tax the employee on the higher of the company car benefit or the salary given up. For most petrol, diesel and many hybrid cars, that removes the saving.
Avoid it: keep the scheme to fully electric cars, or to low-emission cars that sit under the 75g/km threshold, and make sure the provider's car list reflects that.
7. Payroll and reporting
The company car benefit must be reported and taxed correctly, and the employer pays Class 1A National Insurance at 15% on the benefit. From 6 April 2027, employers must report company car benefits through payroll rather than on P11D forms. Mistakes create tax bills for employees and penalties for the employer.
Avoid it: involve your payroll provider before launch, confirm how the provider supplies data, and test the first month's payroll carefully.
8. Duty of care
A salary sacrifice car is a company car. As the employer, you have responsibilities for the people driving it on business, including licence checks and a sensible driving policy.
Avoid it: add salary sacrifice drivers to your existing company car or driving-at-work policy, and check driving licences before the car is delivered and periodically after.
9. Unfair eligibility rules
Limiting the scheme to certain grades, or excluding part-time or lower-paid staff without a clear reason, can cause resentment and, in some cases, discrimination risk. The minimum wage rule means some employees cannot join, which needs explaining carefully.
Avoid it: set objective eligibility criteria, such as a permanent contract, completion of probation and a minimum pay level for the minimum wage test, and apply them consistently.
A pre-launch checklist
Written scheme policy covering leavers, family leave, sickness and pay changes
Contract variation template reviewed by an employment adviser
Minimum wage test built into the application process
Early termination protection confirmed, with exclusions understood
Payroll provider briefed and data flow tested
Car list limited to electric or low-emission models
Driving-at-work policy updated and licence checks in place
Clear employee guide explaining the costs and downsides, not just the savings
Is it still worth doing?
For most employers, yes. Set up properly, a scheme gives staff access to a new electric car at a real saving, and the employer usually makes a modest saving too: about £55 a month per car in our worked example, after Class 1A National Insurance. The Budget on 28 October 2026 left car salary sacrifice unchanged. The risks above are manageable, but they need managing before launch, not after the first leaver.

Frequently asked questions
Who pays if an employee leaves mid-agreement?
It depends on the scheme. Good providers include early termination protection for common situations. Without it, the cost can fall on the employer unless the employment documents allow recovery from the employee.
Can a small business offer salary sacrifice cars?
Yes. Many schemes work for businesses with just a handful of employees. The same compliance points apply.
Does the employer need to be VAT registered?
Not necessarily, but VAT treatment affects the cost of the scheme. Ask the provider and your accountant how it applies to you.
Can directors use the scheme?
Usually, yes, on the same terms as other employees, and the savings are often largest for higher earners. Check the effect on your own salary and dividend planning with your accountant.
What happens at the end of the agreement?
The car is returned, subject to fair wear and tear and mileage checks. The employee can usually choose a new car through the scheme.
