Reporting a fuel card to HMRC for personal mileage

My employer has provided me with a fuel card to use for BOTH business and personal mileage (note I will not be paying them back for the personal mileage therefore my personal mileage will be taxable), do I have to report this fuel card to HMRC or does my employer? Or do I need to wait until it shows up on my P11D form?

Hi,

Your employer will report this to HMRC after the year ends through the P11D.

If you wish to inform HMRC earlier than this you can do by contacting our Income Tax team.

Thank you.

Hello, I have to report private fuel use on a P11D. Please can you advise what section this comes under?
