Company Car Tax Explained

When a company car is allowed to be used for personal use by an employee outside of work hours, then this is deemed a 'benefit in kind' (BIK) and there is a tax due on a vehicle known as company car tax. 

The calculation for the tax of the vehicle is a complicated process. The amount of car tax due will vary depending on a number of factors, including the vehicle P11d, Co2, and your personal tax bracket. 

We've made the process nice and simple with our Company Car Tax Calculator.

What is Company Car Tax?

Anyone using a company car outside of working hours (e.g. for private use) will be required to pay company car tax to HMRC.
This is due to the fact you are getting a "benefit" by being allowed to use your work vehicle privately. This benefit is then called a Benefit In Kind or commonly shortened to BiK. A BiK is any benefit that an employee receives in addition to their salary.

How is Company Car Tax Calculated in the UK?

The process to calculate your company car tax can be confusing and complicated, but our car tax calculator makes the process very easy.

In a nutshell, you are taxed your regular income tax rate on a percentage of your company car's P11D Value.

The percentage that you pay will vary based on the C02 of the vehicle and your personal tax band.

What is a P11D Value?

The P11D is the value of the car that HMRC uses to work out the tax of a vehicle. It takes the manufacturer's list price of the vehicle, including any options that have been added to the car that aren't deemed as standard, less the first-year VED (Vehicle
Excess Duty).

What are the Different Ways to Reduce Company Car Tax?

There are a few different ways to reduce company car tax, including:

● By making a partial payment towards the car's cost, you can decrease the P11D
value of the vehicle, resulting in a reduction in the amount of company car tax you are liable for.
● Opting for a car with low CO2 emissions is advantageous as it attracts a lower tax rate. Therefore, choosing a vehicle with low CO2 emissions will help in reducing your company car tax obligations.
● Minimising the number of private miles driven in the car will also help in lowering the amount of company car tax you owe. Since the tax is based on the distance covered for personal use, reducing private mileage will result in a reduced tax liability.

What Factors Does the Company Car Tax Calculator Take into Account?

The company car tax calculator takes the following factors into account:

● The P11D value of the car.

● The car's CO2 emissions.

● The number of private miles you drive.

● Your personal tax rate.

Does Company Car Tax Affect My Salary?

When an employee joins a company car scheme, they are required to pay Benefit-In-Kind (BIK) tax as the provision of a company car is considered an additional benefit provided by the employer, alongside the annual salary. The amount of tax an employee owes is determined by various factors including the market price of the vehicle, the individual's income tax band, the car's age, fuel type, CO2 emissions, and engine size.

It's worth mentioning that if the company car scheme includes fuel, the employee will also be liable to pay tax on their annual fuel allowance.
