Company Cars: Working Out Taxable Value

Employers providing company cars to employees, company directors managing vehicle benefits, and HR and payroll teams managing company car benefits.

Clarifying how to calculate the taxable value of company cars, the impact of CO2 emissions and fuel type on the taxable value, and the reporting requirements for company car benefits.

Understanding how to calculate the taxable value of company cars is crucial for ensuring compliance with HMRC rules. Incorrect calculations can lead to penalties, P11D reporting requirements, and other tax implications for employers and employees.

How to Calculate the Taxable Value of a Company Car

Where an employee with a company car is provided with fuel for their own private use by their employers, the default position is that the employee is required to pay the car fuel benefit charge. The charge is determined by reference to the CO2 rating of the car applied to a fixed amount, currently £27,800. For example, a CO2 rating of 150g/km would create a taxable benefit of £9,730.

The taxable value of a company car is determined by several factors, including:

• List price (including VAT and delivery costs)
• CO2 emissions and the fuel type (electric vehicles benefit from lower tax rates)
• The percentage of the car’s list price that is taxable, based on its CO2 emissions and fuel type

The higher the CO2 emissions, the higher the taxable benefit. Electric vehicles (EVs) are taxed at a lower rate due to their lower emissions.

The Impact of CO2 Emissions and Fuel Type on the Taxable Value

The vehicle’s CO2 emissions and fuel type determine the tax rate applied to the vehicle’s list price:

• For higher-emission vehicles (e.g., petrol or diesel), the percentage of the list price subject to tax is higher.
• Electric vehicles (EVs) benefit from a lower taxable value due to their minimal emissions.
• The WLTP (Worldwide Harmonized Light Vehicle Test Procedure) standard is used to measure CO2 emissions and fuel efficiency, directly affecting the tax rate applied to the vehicle.

Employers should carefully track the emissions levels and fuel types of their fleet to determine the correct taxable benefit for each vehicle.

How to Report the Taxable Value for Tax Purposes

Once the taxable value of the company car has been calculated, it must be reported to HMRC:

• The taxable value must be declared on the P11D form for each employee receiving a company car.
• The car’s taxable value will be added to the employee’s taxable income for the year, subjecting it to Income Tax and National Insurance.
• If the car is used exclusively for business purposes, there may be exemptions or adjustments to the taxable value.

Employers should ensure that they accurately report the taxable value of each company car to avoid penalties and other tax issues.

Real-World Application

Common scenarios where company car benefits need to be managed include:

• Company car fleets, where multiple vehicles are provided for both business and personal use
• The use of electric vehicles (EVs), which benefit from lower taxable rates compared to petrol and diesel cars
• Calculating and reporting taxable benefits for company cars correctly, ensuring compliance with tax regulations

Employers should regularly review the taxable value of their fleet to ensure they are complying with tax rules and taking advantage of the most tax-efficient options.

Risks and Compliance Considerations

Failure to accurately calculate or report the taxable value of company cars can lead to:

• A taxable benefit for the employee
• P11D reporting requirements and potential penalties
• Class 1A National Insurance liabilities for the employer

Regularly reviewing the taxable value of company cars and ensuring proper reporting can help avoid these risks.
