as above, has anyone ever done this?? i starrted a new job in which i thought we were given a petrol allowance, i was wrong, we are given a form to fill in and send of to tax office in april. i was just wondering how you go about proving you mileage to tax office? do i need to be keeping all my petrol receipts and loggin my mileage everyday? cos, obviously i use my car for personal use aswell as work.
any advice will be greatful, thanks :)
