Company Cars: Taxable Benefits Explained

Understanding the Taxable Benefit of a Company Car

For many businesses, providing a company vehicle is an essential part of daily operations. Whether it's a car or a van, the decision to purchase or lease, typically for a three-year period, carries significant tax implications for both the employer and the employee. As the UK's tax landscape evolves, particularly with a strong governmental push towards decarbonisation, understanding these implications is crucial.

The government's strategy increasingly favours vehicles with lower CO2 emissions, and this is reflected in tax charges and incentives. The transition to electric vehicles (EVs) is a key priority, with ambitious targets to phase out new internal combustion engine (ICE) vehicles by 2030 and all new car and van sales being zero-emission by 2035. This commitment is backed by investments in charging infrastructure and continued tax incentives for EVs.

However, it's important to note that even driving a fully electric company vehicle can become more expensive from a tax perspective. Benefit-in-Kind (BIK) rates for zero-emission cars are set to increase, as are the rates for hybrid vehicles, bringing them more in line with ICE vehicles. Furthermore, changes are being introduced for double cab pick-up vehicles, which will be taxed as company cars from April 2025, though transitional relief is available for existing contracts.

Company Car Tax: The Employee's Perspective

A company car is considered a 'benefit in kind' (BIK) by HMRC, meaning the employee must pay income tax on it. This taxable benefit is calculated using a formula:

Taxable Benefit = List Price of the Car × Taxable Benefit Percentage

The taxable benefit percentage is determined by the car's CO2 emissions and its electric mileage range. Generally, lower emissions and a higher electric range result in a lower taxable benefit.

Benefit-in-Kind (BIK) Rate Changes

The government has announced upcoming changes to BIK rates, providing some certainty but also indicating an upward trend for all vehicle types. Here's a snapshot of the projected changes:

Note: Specific rates for intermediate CO2 bands will also increase. Diesel cars not meeting RDE2 standards may incur a 4% supplement.

Example Scenario

Consider a company car with CO2 emissions of 30 g/km and an electric range of 50 miles. The taxable benefit percentage is projected to rise from 8% to 19% between 2024/25 and 2029/30. For a car with a list price of £35,000:

• 2024/25 Tax Year: Taxable benefit of 8% = £2,800. A higher-rate taxpayer (40%) would pay £1,120 in income tax.
• 2029/30 Tax Year: Taxable benefit of 19% = £6,650. The same higher-rate taxpayer would pay £2,660 in income tax.

Employees can reduce their taxable benefit by making a capital contribution towards the purchase of their company car, up to a maximum of £5,000.

Company Van Benefits

The tax calculation for a company van is considerably simpler, as it doesn't take into account the list price, CO2 emissions, or electric mileage range. For the 2025/26 tax year:

• Zero CO2 Emissions: Taxable benefit is £0.
• Above 1 g/km CO2: Taxable benefit is £4,020.

This taxable benefit is taxed at the employee's marginal rate of income tax. A key distinction for vans is that if a van is used only for commuting or insignificant private use, no taxable benefit arises. This is not the case for company cars.

Important Note: From April 2025, double cab pick-up vehicles will be taxed as company cars, not vans. Transitional relief is available for vehicles contracted before 5 April 2025, until 5 April 2029. This might present an opportunity to secure favourable tax treatment by purchasing these vehicles before the deadline.

Company Car and Van Fuel Benefit

If an employer covers all fuel costs, including private journeys, a separate taxable benefit arises unless the employee fully reimburses the employer for private fuel. If the employee pays for all fuel and is only reimbursed for business mileage, no taxable benefit occurs.

The taxable fuel benefit is calculated as:

Taxable Fuel Benefit = £28,200 × Taxable Benefit Percentage (based on CO2 and electric range)

For company vans, if free or subsidised fuel is provided for private use, the taxable van fuel benefit for 2025/26 is £769. Contributions towards private fuel for a van do not reduce this taxable benefit.

Vehicle Excise Duty (VED) and Electric Vehicles

VED rates are set to be uprated from April 2025. Crucially, the First Year VED rates for new cars registered from 1 April 2025 will be adjusted to further incentivise zero-emission vehicles:

• Zero Emission Cars: Lowest first-year rate of £10 until 2029-30.
• 1-50 g/km CO2 (incl. Hybrids): £110 for 2025-26.
• 51-75 g/km CO2 (incl. Hybrids): £130 for 2025-26.
• 76+ g/km CO2: Rates will double from their current level for 2025-26.

Electric Charging Benefits

Providing electric charging at the workplace is a tax-free benefit for employees, provided it's available to all staff. Similarly, the installation of an electric car charger at an employee's home for a company electric car is also tax-free. However, if the employer pays for a home charger for an employee's private vehicle, this constitutes a taxable benefit.

Corporation Tax Relief for Businesses

Businesses purchasing company cars can claim Corporation Tax deductions through capital allowances:

Vans and commercial vehicles are eligible for 100% Annual Investment Allowance (AIA), up to a limit of £1 million. Permanent full expensing relief at 100% is also available for companies.

Leasing Company Vehicles

Lease costs are treated as allowable revenue expenditure. For operating leases, the total expense is the lease rentals. For finance leases, it's the finance lease interest and depreciation. A restriction applies to lease rentals for cars with CO2 emissions exceeding 50g/km, where 15% of the expenses are disallowed for tax purposes.

Enhanced Capital Allowances (ECA)

ECAs offer 100% tax relief on qualifying expenditure for new zero-emission cars, goods vehicles, and electric vehicle charging points incurred by 31 March 2026. Gas refuelling stations also qualify, but ECA cannot create a repayable tax credit for these.

Reporting Obligations

Benefits provided to employees must be reported to HMRC via a P11d form by 6 July following the tax year end. Class 1A National Insurance Contributions (NICs) are payable by the employer at 13.8% (rising to 15% from 2025/26) on the value of these benefits, due by 22 July.

Frequently Asked Questions

Q1: Is a company car always a taxable benefit?

Yes, generally, a company car provided for an employee's use is considered a benefit in kind and is subject to income tax. The amount of tax depends on the car's CO2 emissions, list price, and the employee's tax rate.

Q2: Can I avoid paying tax on a company van?

If a company van is used only for commuting or insignificant private use, no taxable benefit arises. However, significant private use will trigger a taxable benefit.

Q3: What is the taxable benefit for an electric company car?

The taxable benefit for electric company cars is currently low (2% BIK rate), but this is set to increase gradually. The exact percentage depends on the year the car is registered and future government announcements.

Q4: How does keeping a company car at home affect tax?

Keeping a company car at home overnight means it's considered available for private use, including commuting. This results in a taxable benefit for the employee.

Q5: Are there tax advantages to leasing a company car?

Leasing costs are generally treated as revenue expenditure, which can be offset against profits. However, a restriction applies to lease rentals for higher-emission cars, reducing the deductible amount.
