If your employer offers you a company car or a car allowance, deciding which to take isn’t always straightforward.
A company car gives you access to a vehicle provided through your employer. A car allowance gives you additional money towards arranging a vehicle yourself.
But the headline value isn’t the whole story. Tax, National Insurance, Benefit in Kind (BiK), insurance, maintenance, depreciation and the type of car you want can all affect which option works best for you.
And if you’re considering an electric car, there’s another possibility worth knowing about: an existing car allowance may be able to form part of an electric car salary sacrifice arrangement.
Here’s what you need to know.
At a Glance: Car Allowance vs Company Car
| Car allowance | Company car | |
|---|---|---|
| What you receive | Cash through payroll | A vehicle provided by your employer |
| Vehicle choice | Generally more freedom, subject to employer policy | Usually limited to your employer’s available vehicles |
| Tax | Generally subject to Income Tax and NI | Usually subject to company car BiK tax |
| Insurance | Usually your responsibility | Often included |
| Maintenance | Usually your responsibility | Often included |
| Tyres and repairs | Usually your responsibility | Often included |
| Depreciation | Your responsibility if you own the car | Generally not your responsibility |
| Ownership | Depends on how you acquire the vehicle | Generally no |
| Flexibility | Usually greater | Depends on the employer’s scheme |
What is a Car Allowance and How Does it Work?
A car allowance is money provided by your employer towards the cost of having a vehicle. Rather than providing the car, your employer normally pays the allowance through payroll alongside your salary. For example, your employment package might include:
£40,000 salary + £6,000 annual car allowance
You then arrange your own vehicle, subject to any requirements your employer has about cars used for work. Depending on your circumstances, you might use the allowance towards buying a car, personal finance, a lease, a vehicle you already own or even to get an electric car through salary sacrifice.
The main advantage is flexibility.
But you’re also likely to be responsible for costs such as:
- Finance or leasing
- Insurance
- Servicing and MOTs
- Maintenance and repairs
- Replacement tyres
- Breakdown cover
- Vehicle tax where applicable
- Depreciation if you own the vehicle
A £500 monthly allowance doesn’t necessarily mean you have £500 available to spend on a monthly car payment.
How is a Car Allowance Taxed?
A car allowance paid as earnings through payroll will generally be subject to Income Tax and employee National Insurance.
That means a £6,000 annual allowance = £500 per month (gross). This won’t necessarily result in an additional £500 reaching your bank account each month. The amount you actually receive will depend on your earnings and individual tax position.
When you’re comparing a car allowance with a company car, look at the net value of the allowance, rather than the headline figure alone.
What is a Company Car?
A company car is a vehicle provided to you through your employer. Instead of receiving additional cash and arranging the vehicle yourself, you have use of an employer-provided car. Depending on the arrangement, costs such as insurance, servicing, maintenance and tyres may also be covered.
You generally won’t own the car, so you won’t have an asset to sell at the end. On the other hand, depreciation is generally not your financial responsibility either.
If the vehicle is available for private use, however, it’s usually considered a taxable benefit. GOV.UK distinguishes cars used solely for qualifying business journeys from cars available for private use when determining the tax treatment.
How is a Company Car Taxed?
Company car tax is based on Benefit in Kind (BiK). The calculation is affected by factors including:
- The vehicle’s taxable/P11D value
- Its applicable BiK percentage
- Your Income Tax rate
The vehicle you’re offered therefore makes a significant difference.
This is particularly relevant for electric cars because zero-emission vehicles currently benefit from lower company-car tax percentages than higher-emission vehicles. The Government has set company car tax (Benefit-in-Kind) at 4% for 2026/27.
So don’t just ask “how much tax will I pay on a company car?”, ask “how much tax will I pay on this company car?”

Car Allowance vs Company Car: What Should you Actually Compare?
This is where the decision becomes more useful.
If you’re taking a car allowance, start with what actually reaches you after tax and National Insurance.
Then consider your complete vehicle costs:
Net car allowance
- Finance or lease
- Insurance
- Servicing and maintenance
- Tyres
- Breakdown cover
- Other vehicle costs
If you own the car, depreciation is worth considering too.
With a company car, look at the tax you’ll pay on the specific vehicle, any contribution you’re expected to make and what costs are included within the arrangement.
That’s why comparing a £500 gross cash allowance with a car that happens to have a £500 monthly lease cost doesn’t tell you very much.
Compare the complete cost of driving the vehicle instead.
What about Business Mileage?
A car allowance and business mileage reimbursement aren’t necessarily the same thing.
Your employer may provide a cash allowance towards having a suitable vehicle while separately reimbursing qualifying business journeys. Different mileage rules can apply to employees driving company cars.
If you regularly travel for work, check your employer’s mileage policy alongside the vehicle benefit rather than assuming your allowance covers everything. We also have government guidance to help.
What is a Reasonable Car Allowance in the UK?
There’s no single figure that makes a car allowance good or bad. It can depend on your employer, role, seniority, expected business travel and the type of vehicle you’re expected to have.
Consider two people receiving exactly the same £6,000 annual allowance. One already owns a reliable car outright. The other needs to finance a newer vehicle and pay for insurance, servicing, maintenance and tyres. The same allowance could look considerably more attractive to the first person.
Instead of focusing solely on whether your allowance is above or below an average, ask: “is the after-tax value of my allowance enough for the car and running costs I actually need?”
Can You Use a Car Allowance with Salary Sacrifice?
Yes, and this is an option employees can easily overlook.
Car allowance and salary sacrifice don’t necessarily have to be competing choices.
Depending on how your employer structures its benefits, an existing cash car allowance may be able to form part of the calculation for a vehicle obtained through salary sacrifice.
The car allowance you receive can be used towards the cost of a salary sacrifice car allowing you to make substantial saving!
For employees interested in switching to an EV, it’s therefore worth finding out what your existing allowance could achieve through your employer’s Electric Car Scheme before deciding how you want to use it.
How Can a Car Allowance Work with the Fleet Evolution Electric Car Scheme?
With Fleet Evolution, an existing car allowance can be taken into account when calculating the cost of an electric car through salary sacrifice.
The principle can be illustrated as:
Gross cost of electric car – applicable car allowance = remaining gross amount
The relevant tax and National Insurance treatment can then be applied to the remaining salary sacrifice amount, with the vehicle’s Benefit in Kind tax also taken into account.
Here’s a completely fictional example to make that easier to understand.
Example: £600 Car Allowance Towards a £650 EV
Imagine you receive a £600 monthly car allowance.
You find an electric car through your employer’s Fleet Evolution scheme with an illustrative gross monthly cost of £650.
Your starting calculation would be:
| Illustrative monthly amount | |
|---|---|
| Gross EV cost | £650 |
| Car allowance | -£600 |
| Remaining gross amount | £50 |
That £50 is the remaining gross amount, not necessarily the final impact on your take-home pay.
The relevant salary sacrifice tax and National Insurance treatment would still need to be considered, alongside the Benefit in Kind tax applicable to the EV. But the example demonstrates something important:
Already receiving a car allowance doesn’t necessarily prevent you from getting an EV through salary sacrifice. Your allowance can potentially form part of the calculation.
You can salary sacrifice the remainder of the cost. You would then apply the relevant Income Tax and National Insurance savings to the remaining £50, before adding the Benefit-in-Kind tax. For accurate salary sacrifice estimations, we have a salary sacrifice calculator.
This example is entirely fictional and is provided solely to explain the principle. It isn’t a Fleet Evolution vehicle quote, personal tax calculation or indication of what an individual employee would pay.
What if you Don’t Receive a Car Allowance?
You don’t need one to get an electric car through salary sacrifice. If your employer offers the Fleet Evolution Electric Car Scheme and you’re eligible to participate, you can access an EV through standard salary sacrifice.
The difference is the starting point:
Already receive a car allowance? It may be possible to incorporate it into your calculation.
Don’t receive a car allowance? You may still be able to access an EV through standard salary sacrifice.
Both can provide a route to an electric car through your employer.
What Does the Fleet Evolution Electric Car Scheme Include?
When comparing your options, it’s important to consider more than the vehicle payment. Fleet Evolution’s Electric Car Scheme includes maintenance, tyres and roadside recovery within the monthly package. That’s particularly relevant if you’re comparing it with using a cash allowance to arrange a car privately.
A £400 private vehicle payment doesn’t necessarily mean your car costs £400 a month once you’ve accounted for the other costs you’re responsible for.
Whatever routes you’re comparing, try to compare like for like.
What Happens if you Leave Your Employer?
This is another practical difference worth considering.
If you own your vehicle or have arranged it privately using your cash allowance, changing employer doesn’t necessarily end that vehicle arrangement. A company car or salary sacrifice vehicle, however, is linked to your employment.
If you’re considering an employer-provided vehicle, check the scheme terms so you understand what happens if you resign, are made redundant or your circumstances change during the agreement.
This isn’t a minor detail: salary sacrifice providers commonly make leaving employment part of their scheme terms and may have provisions around early termination. Check out the best salary sacrifice schemes to compare which will be best for you!
Car Allowance or Company Car: Which is Right for You?
There’s no universal winner.
A car allowance could suit you if you already own a suitable vehicle, want more control over what you drive, prefer the possibility of vehicle ownership or value flexibility over how you use the benefit.
A company car could suit you if you’d rather not own the vehicle, value predictable motoring costs or want more of the responsibility for running the car handled through your employer.
An electric car scheme could be worth exploring if you’re interested in a new EV through your employer, whether you currently receive a car allowance or not.
Before deciding, ask yourself five questions:
- What is the actual after-tax value of my car allowance?
- What does my own car really cost me each month?
- What company car am I actually being offered, and what is its BiK?
- What’s included with each option?
- Do I want to own the vehicle?
Those answers are much more useful than choosing whichever benefit has the biggest headline number.
