The Director's Guide to Company Car Leasing (2026/27)
I've written enough about facelifted hatchbacks and grey paint names to know that most people reading a car blog want to talk about the drive. Directors reading this one want to talk about something else entirely: what the car actually costs them once HMRC has had its say. So that's what this guide does. No fluff, no "vibes only" review. Just what a company car costs a UK director in 2026/27, how leasing changes the maths, and how to decide whether it's the right call for your business.
Quick note before we start: this is general guidance, not personal tax or financial advice. Rates, thresholds and allowances change, and your own numbers depend on your company's structure and your personal tax position. Always check your specific situation with your accountant before committing.
The short answer
If you're a director asking "what's the company car tax rate right now," here it is:
Fully electric cars: 4% Benefit in Kind rate for 2026/27, rising to 5% in 2027/28, 7% in 2028/29, and 9% by 2029/30.
Plug in Hybrid (PHEV): 7% Benefit in Kind rate for 2026/27, rising to 8% in 2027/28, and 18% in 2028/29.
The company pays Class 1A National Insurance at 15% on top of whatever taxable value applies to the car.
Everything below explains how those numbers actually hit your pocket, and your company's tax bill.
How company car tax actually works
Company car tax is a Benefit in Kind charge. If your limited company provides a car you can also use privately, HMRC treats that private use as a taxable benefit, and it's calculated in three steps:
Take the car's P11D value (this is the list price excluding the first years road tax & first reg fee currently £55).
Multiply by the Benefit in Kind percentage for that car (set by CO2 emissions and fuel type).
Multiply by your income tax rate (20% or 40%, depending on your other earnings).
One detail that trips directors up constantly: the calculation always uses the manufacturer's list price, not what you actually paid. Negotiate a discount all you like, HMRC still uses the P11D figure, so check it with your dealer or broker before you commit to a lease.
The company side of the bill is separate. Your business pays employer Class 1A National Insurance at 15% on the same taxable value, and reports the whole thing through a P11D and P11D(b), due by 6 July following the end of the tax year.
The 2026/27 Benefit in Kind rates
Vehicle type 2026/27 BIK rate Trend
Fully electric 4% 5% (2027/28), 7% (2028/29), 9% (2029/30)
Plug-in-Hybrid 7% 8% (2027/28), 18% (2028/29)
What that means in real numbers
Take a director on the 40% tax rate:
• Electric car, £45,000 P11D value: taxable benefit of £1,800 (4%), income tax of £720 a year, around £60 a month.
• Plug in hybrid, £45,000 P11D value: taxable benefit of £3,150, income tax of £1,260 a year, around £105 a month.
Same list price, wildly different tax bill. That gap is the entire reason electric company cars became the default recommendation for directors, and it's still true in 2026/27, even with the rate ticking up from last year.
Salary sacrifice for electric cars: does it work for a sole director?
Most salary sacrifice arrangements were squeezed hard by the Optional Remuneration Arrangement rules introduced in 2017. Electric vehicles are the exception. An EV salary sacrifice scheme still lets you give up gross salary in exchange for the car, and you're taxed on the Benefit in Kind value rather than on the salary you gave up, which is a much smaller number.
Yes, this works for single director companies too. There's no headcount restriction, but the arrangement needs to be documented properly with a written variation to your employment contract, not just an informal agreement. If you're the only person on the payroll, get this paperwork right; it's the difference between a clean tax position and an HMRC challenge later.
Corporation tax and the First Year Allowance
The company side of an electric car purchase has its own incentive. New, unused, fully zero emission cars bought before 31 March 2027 (for corporation tax) or 5 April 2027 (for income tax and sole traders) qualify for a 100% First Year Allowance, meaning the company can deduct the full purchase cost against profits in the year of purchase. This deadline was extended from the original 31 March 2026 cut off, so if you were told this incentive had already closed, check again.
Leasing changes this picture. On a lease, you're not buying the asset, so the First Year Allowance doesn't apply in the same way, but lease rentals are generally deductible against corporation tax as a business expense, which is the trade off worth understanding before you decide between buying and leasing.
Company car vs car allowance: the director's decision
This is the comparison every director eventually runs, and the honest answer is: it depends on the car.
Cash allowance, added to salary, gets taxed like pay: income tax, employee National Insurance, and employer National Insurance in full, with no Employment Allowance relief if you're a sole director company. There's no way around that.
Electric company car: small 4% Benefit in Kind charge, plus the corporation tax relief above. For most sole director companies choosing an EV, the company car route wins on tax.
Petrol or diesel company car: the equation flips back toward a cash allowance once you're in the higher CO2 bands, because a 37% BIK rate erodes the advantage fast.
The short version: electric tips the maths firmly toward a company car. Petrol and diesel need a proper side by side calculation, because the answer isn't as clean.
Where leasing fits into all of this
Buying and leasing solve different problems. Leasing keeps the vehicle off your balance sheet, avoids a large upfront cash outlay, and gives you a fixed monthly cost that's straightforward to budget against, which matters more to most SME directors than owning the asset outright ever does.
At VCEA, we work with directors and SMEs across East Anglia, Cambridge, Norwich, and Peterborough, structuring company car and salary sacrifice leases that fit how your business actually runs, not a generic fleet template. As an FCA and BVRLA regulated business, we can talk you through the numbers above against your specific company structure, and find the lease that matches the tax position you're trying to hit.
Frequently asked questions
What is the Benefit in Kind rate for an electric company car in 2026/27? 4%, rising to 5% in 2027/28, 7% in 2028/29, and 9% by 2029/30, under HMRC's published schedule.
Does salary sacrifice for an electric car work if I'm the only director? Yes. There's no restriction based on company size or headcount, but the sacrifice needs to be documented with a formal variation to your employment contract.
Is company car tax based on what I paid for the car, or the list price? The list price. HMRC uses the P11D value, which includes options and delivery, regardless of any discount you negotiated.
Can I still get 100% First Year Allowance on an electric company car? Yes, if the car is new, unused, and fully zero emission, and purchased before 31 March 2027 for corporation tax purposes. This is for outright purchase, not leasing.
Is a company car or a car allowance better for a director? For electric vehicles, the company car route usually wins on tax. For petrol and diesel, it depends on the car's CO2 band and needs a direct calculation.
This guide reflects publicly available HMRC and GOV.UK guidance on company car tax as of 2026/27. It is general information, not personal tax or financial advice, and rates are subject to change. For BIK examples we have used a BYD Seal U Comfort. Speak to your accountant or to VCEA before making a leasing decision based on these figures.
