Company Car Mileage Rates Explained: An Easy Guide for Business Owners and Employees

Company cars are a great benefit for employees and businesses. But, when it comes to calculating travel expenses, the experience of using a company car can be a little less pleasant. We made this guide to help put all the confusion to rest. Learn what company car mileage rates are, why they’re necessary, and why every company and working individual can profit from a better understanding of the issue.

Company cars give employees a convenient means of transport that they can use to travel to work, and simplify business trips or personal rides. Therefore, it’s usually considered a wonderful gesture of trust and gratitude to hand over the keys to a leased vehicle. In return, the business profits from higher employee motivation and flexibility. The tricky thing is: Employees often need to pay for petrol themselves and then get reimbursed for work trips at a later date. These petrol station stops can quickly rack up some serious business expenses.

In general, companies are more than willing to pay for them. But, instead of simply reimbursing the amount on the receipt, they will often opt for a tax-free solution. This is where the company car mileage rates set up by the government come into play. HMRC has the following rule: Corporate expenses are not subject to tax or Class 1A National Insurance fees if there is no profit made from the expense. This means: companies do not get taxed for the one-for-one reimbursement of business expenses, and can even reduce taxes.

To stay in line with HMRC regulations, most businesses adhere to the company car mileage rates which are also often called advisory fuel rates. These have proven to be an efficient way to handle fuel rates in accounting and HMRC. Instead of taking every make and car model into account, these rates apply to the vast majority of vehicles driven in the UK.

When do company car mileage rates apply?

So, to sum up the question in which cases company car mileage rates apply, two common scenarios are important for companies and employees alike.

  • Reimbursement for business travel expenses in a company car driven by an employee
  • Repayment of fuel costs when an employee uses a company car for private trips

However, the advisory fuel rates are not set in stone. They do not apply for vans. Hybrid cars, on the other hand, can be treated as cars fueled by diesel or petrol. Also good to know for employers: Reclaiming input VAT is only possible with a valid receipt handed in by the employee. 

Employers can also apply their own rate, which can be useful for very efficient cars or when the business travel cost is higher than the HMRC guideline rate. They should keep in mind that a higher rate without fully explaining the higher cost per mile must be treated as taxable profit. The amount is also considered earning for Class 1 National Insurance.

Why do advisory fuel rates change?

Why do advisory fuel rates change?

Considering the current state of the world, technology has to develop quickly to keep up with demand and fuel alternatives. On top of that, fuel and energy prices are constantly changing due to the ups and downs of the world market, availability, and political situations. 

As inflation hits consumers, advisory fuel rates need to adapt, too. That is why HMRC is evaluating on a quarterly basis if rates need to be adjusted to reflect the current financial situation of taxpayers.

But how does HMRC calculate the advisory fuel rate? An important factor is MPG (the miles per gallon value) which is taken from manufacturers’ information. This is taken into relation to how many specific car models are corporate-owned. The applied MPG is 15 percent lower than average to reflect realistic driving conditions and optimised fuel efficiency.

Of course, the current fuel price is also taken into account. This is provided by the Department for Business, Energy, and Industrial Strategy. Regarding the LPG price (liquified petroleum gas), the Automobile Association is handing out data.

What are the benefits of a company car?

What are the benefits of a company car?

Driving a company car comes with plenty of benefits for employees, especially when the employer allows private use. In contrast to a car allowance, where money is added to the annual salary to pay for fuel, maintenance, or a new set of tires, team members do not have to maintain, buy or lease a car of their own. The business takes care of all things related to the car, so the employee can simply enjoy driving it. After a few years, they usually receive a new model, too, so thanks to corporate leasing contracts, team members can even profit from driving the most efficient cars on the market.

It is ideal for commuters who travel long distances every day and cannot or do not want to own a personal vehicle. However, employees need to consider the benefit-in-kind. Luxurious models with high CO2 emissions might result in higher taxes than a more efficient car. So we suggest that employees should have a say in the car selection to avoid unnecessary financial pressure.

Why company cars can be the right decision for businesses

Having a corporate fleet of cars can boost a business thanks to more flexible work hours and quick interactions with clients. Of course, every company should crunch their numbers to see whether leasing or even buying company cars really makes sense. The following factors are essential to gather information on the costs:

  • Monthly lease payment or one-time payment
  • Fuel costs
  • Insurance
  • Taxes and registration costs
  • Maintenance and repairs for damages

The total can be compared to the estimated cost per month for each team member’s possible mileage reimbursement. But numbers are not the only factor in this equation. If a business has trouble finding skilled, resilient, and highly motivated employees, offering a company car might be the right way to go. In the long run, spending a few more pounds can be the best decision a CEO has ever made if it means that team members enjoy working for them and their vision. Moreover, company cars can make for free advertisement. Stickers or magnets on the vehicle are seen by hundreds of people every day. A fleet of cars therefore can reach potential clients and partners alike.

What is the BIK car tax?

The BIK is short for benefit-in-kind. This tax affects employees who receive company benefits on top of their salary. The most prominent example is a company car that often can be used for private matters, as well. In those cases, employees will have to make a tax contribution by paying the BIK.

This company car tax can vary according to several factors: P11D value (the list price mentioned in the benefits and expenses form) and the car’s CO2 emissions. To calculate the company car or BIK tax, the P11D value is mandatory. This is multiplied by the BIK percentage banding and again multiplied by the individual tax band. To simplify the process, it is also possible to use a comprehensive online tax calculator.

How do I profit from a company car?

Employees can profit from driving a company car if they are commuting to work or going on business trips several times a year. Businesses, on the other hand, can motivate their team members, profit from tax reductions, and even find better staff with the help of this great benefit.

Why should employees keep an eye on the BIK car tax?

If a company car is not very efficient and produces lots of CO2 emissions, the benefit-in-kind tax can be higher than with efficient and more sustainable solutions. Therefore, team members should check if they can handle the respective tax connected to the chosen vehicle.
