Fuel card from work for a private car - P11D

pete1975

morning all i was provided a fuel card in 2024 and was allowed to use it for fuel for both business and personal mileage.   the company pulled the plug on the cards in March 2025.   for the calculation of tax, is it 40% I have to pay on the amount showing on the P11D, or do i have have to pay the amount on the P11D?     Around 20-30% was business mileage, driving to sites or customers how do i declare this to HMRC company accountant just said its my responsibility and when i google its talks about company car benefits and fuel,   i don't have a company its my own car i use. 

thanks

The amount in the P11D is a taxable benefit charged at your marginal rate, so you will pay 40% of this.
But you can also claim tax relief for the business mileage at 45p for the first 10k miles and 25p for anything over.

If you already do self assessment then yes, if you dont otherwise do self assessment then no, see https://www.gov.uk/tax-relief-for-employees/vehicles-you-use-for-work

It's not being counted at all, your gross pay is just your basic less pension and its not being included in the deductions. 

If its deducted from your gross pay then you'd have to pay BIK on it as no tax has been paid, if its taken from your net pay then no BIK is required as you've already paid tax. But here its not being minused at all

Presumably you have kept a detailed mileage log. In the absence of proper records the HMRC may assume it to be all private.

I do, i have a calendar with the dates and so where i went because i had to create a visit report aswell.  I would just have to google map the mileage for each visit.

thanks the payroll lady at work finally come back to me and said you do not have to worry,   that tax has been paid,   i have to always check this box where it says ''amount made good or from the tax deducted'' 

but then i've had to go back and say but the fuel is showing the same thing....
