First things first, what is a car fuel benefit?

How to report car fuel benefits to HMRC 

Your reporting options

1. P11D Form:

Submit this form at the end of the tax year, along with other benefits.

2. Payroll:

Process the car fuel benefit through payroll, deducting tax in real time.

Important update

From 2026, payrolling benefits will become mandatory.  
 
This means that if you are currently using P11D forms you should consider switching to payroll processing now to stay ahead of the change. 

Tax and Class 1A National Insurance Contributions on car fuel benefits

Your people 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 are assigned a lower percentage, whereas those with higher emissions receive a higher percentage, varying from 2% to 37%. 
 
Your company 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 people (currently at a rate of 13.8%). 

What method is used to calculate the fuel rates? 

Here’s a brief explanation of how HMRC calculates their fuel rates: 

1. Mean MPG calculation: HMRC starts 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 doing all this, HMRC ensures that the advisory fuel rates are accurate and reflective of real driving conditions and fuel costs. Here is the calculation breakdown: 

Diesel 

Engine size (cc)	Mean MPG	Fuel price (per litre)	Fuel price (per gallon)	Rate per mile	Advisory fuel rate
Up to 1600	56.7	149.4p	679.0p	12.0p	12p
Between 1601 and 2000	48.0	149.4p	679.0p	14.2p	14p
Over 2000	36.3	149.4p	679.0p	18.7p	19p

 FAQs

Is it worth taking a company car?

Whether an employee should use a company car hinges on how much they drive and spend on fuel. If they rack up a lot of miles and their fuel costs exceed the car’s fuel benefit, it’s a good deal. However, if their fuel expenses are low, they could actually end up paying more with the benefit.
