Company Car, Van and Fuel Rates for 24/25

Do your employees use their company-owned vehicles outside of work? If so, it’s crucial that you stay informed about car fuel benefits.

Understanding the 2024/25 rates, knowing how to accurately report to HMRC, and being aware of the associated tax and National Insurance implications can help you manage these benefits effectively.

Whether you’re a business owner, HR manager, or senior accountant, staying up to date on these aspects ensures compliance and optimises the management of your company’s vehicle expenses.

Let’s get started.

Car fuel benefit: what is it?

When you provide a company car and cover the cost of fuel for your employees’ personal use, they are subject to a company car fuel benefit tax. HMRC regards this fuel as ‘free fuel’, and it is taxed accordingly.

This means that although the fuel is paid for by your company, your employees will still incur costs due to the associated tax. If your company does not subsidise this benefit, your employees will be taxed based on the value of the free fuel provided.

Understanding and managing this benefit is crucial to ensure compliance and to inform your employees of their tax obligations.

How can you process and report car fuel benefit to HMRC? 

You have two ways to report car fuel benefit to HMRC:

1. P11D form: submit this form at the end of the tax year, as with other benefits. 
2. Payroll: process the car fuel benefit through payroll, deducting tax in real time. 

Note that starting in 2026, payrolling benefits will become mandatory. If you’re currently using P11D forms, it’s a good time to switch to payroll processing. 

Tax and Class 1A NICs on car fuel benefit

Your employees must pay tax on any car fuel benefit they receive. The taxable value is calculated using HMRC’s appropriate percentage, which considers the car’s CO2 emissions.

Cars with lower emissions have a lower percentage, while those with higher emissions have a higher percentage, ranging from 2% to 37%.

Your organisation also has contributions to make. You’ll need to pay Class 1A National Insurance Contributions on the value of the car fuel benefit provided to your employees (currently at a rate of 13.8%). 

How are the fuel rates calculated? 

Fuel rates are calculated using a straightforward process set by HMRC, so you don’t need to worry about the details.

However, here’s a brief explanation:

1. Mean MPG calculation: HMRC begins by determining the mean miles per gallon (MPG) based on manufacturers’ data. This figure is adjusted to reflect the distribution of specific models sold to businesses.
2. Applied MPG adjustment: the mean MPG is then reduced by 15% to account for real-world driving conditions, recognising that actual fuel efficiency is often lower.
3. Fuel price data: HMRC sources the petrol prices from the Department for Business, Energy, and Industrial Strategy, while LPG prices are taken from the Automobile Association website.
4. Rate calculation: using the adjusted MPG and current fuel prices, HMRC calculates the advisory fuel rates.  

By following these steps, HMRC ensures that the advisory fuel rates are accurate and reflective of real driving conditions and fuel costs. 

Let’s take a look at the calculation breakdown:

Engine size (cc)	Mean MPG	Fuel price (per litre)	Fuel price (per gallon)	Rate per mile	Advisory fuel rate
Up to 1400	49.5	140.6 pence	639.0 pence	12.9 pence	13 pence

FAQs 

How often do HMRC update the advisory fuel rates?

HMRC revise the advisory fuel rates quarterly to reflect changes in fuel costs. Theses revisions happen on the following dates: 

• 1 March 
• 1 June 
• 1 September 
• 1 December 

Do you have to use HMRC’s advisory fuel rates? 

The advisory fuel rates set by HMRC serve as a guideline and are not mandatory. If for instance, a company car consumes more fuel than the advisory rate covers, both employees and employers can be reimbursed at a higher rate. This is possible if the employer can prove the car’s higher fuel consumption. Similarly, lower fuel rates can be used for more economical cars.
