Company cars & vans - how they’re taxed and what to watch out for

Company vehicles can be a useful perk and a genuine business tool, but the tax treatment for cars and vans is very different. Understanding the basics can help you decide which option (if any) is right for you as a director or employee.

Company cars: when they create a benefit in kind

If a company car is available for private use (including home‑to‑work travel in most cases), HMRC treats it as a benefit in kind. This means:

• The employee/director pays Income Tax on the value of the benefit.

• The company pays Class 1A National Insurance on the same benefit value.

The taxable value is based on several factors:

• The car’s list price (not necessarily what you actually paid).

• The car’s CO₂ emissions and fuel type.

• Whether fuel is also provided for private use.

Generally, the higher the emissions and list price, the higher the taxable benefit. That’s why company cars can be surprisingly expensive from a tax point of view—particularly for higher‑rate taxpayers—if the vehicle is petrol or diesel with relatively high emissions.

Low‑emission and electric company cars can be far more tax‑efficient, because the benefit‑in‑kind percentage is much lower. Even then, it’s important to run the numbers to compare against alternatives, such as using your own car and claiming mileage.

Fuel for private use

If your employer or company pays for your private fuel, this usually creates an additional taxable benefit, based on a fixed “fuel benefit” figure set by HMRC each year.

In many cases, this fuel benefit is poor value from a tax perspective unless your private mileage is very high. It’s often more efficient for the driver to pay for their own private fuel rather than trigger the fuel benefit charge.

We routinely check whether the fuel benefit is actually saving money or simply generating extra tax and NI.

Company vans: generally more favourable

Company vans are treated more generously than cars for tax purposes, especially where they’re genuinely used as work vehicles.

If a van is used only for business and what HMRC calls “insignificant” private use (for example, occasional personal errands on the way home), there may be no taxable benefit at all.

Where there is regular private use, HMRC typically applies:

• A fixed benefit charge for the van itself, plus

• A separate fixed benefit for any private fuel provided.

These amounts are usually much lower than equivalent company car benefits. That’s why, for certain trades and roles where a van is appropriate, they can be significantly more tax‑efficient.

However, HMRC expects the vehicle to be a genuine van, used mainly for work, and the company should have a clear policy on private use.

Ownership and running costs

For both cars and vans, the company usually:

• Buys or leases the vehicle, and

• Claims tax relief on running costs and, in some cases, capital allowances or lease deductions.

This can help smooth cash flow and keep vehicle costs within the business. But for the user, the personal tax impact of any benefit in kind must be factored in.

Sometimes, it’s more efficient for an individual to own the car personally and claim business mileage from the company instead, using HMRC’s approved mileage rates. The best answer depends on:

• The type of vehicle,

• Expected mileage (business vs private), and

• Your personal tax position.

Choosing the right structure

The “right” answer isn’t the same for everyone. Some key questions to consider are:

• Is the vehicle mainly for business or personal use?

• Would an electric or low‑emission car change the numbers?

• Is a van appropriate for the role, and is there a solid business case for it?

• Would using a personally ownedvehicle with mileage claims be simpler and cheaper overall?

We help clients by:

• Comparing the tax and NI impact of cars vs vans vs personal ownership.

• Running through different vehicle and fuel scenarios.

• Making sure any benefits are reported correctly to HMRC.

• Designing policies around private use so the rules are clear and compliant.

If you’re considering a company car or van, it’s worth getting advice before you sign the lease or make the purchase. A short conversation and some calculations upfront can prevent costly surprises later.
