Ever since Ive been self-employed Ive always used the 40p per mile allowance for the running costs of any vehicle Ive had. Its been this level of relief since before the dinosaurs. Who uses the 40 p allowance and who keeps their receipts for all vehicle costs.
Im sure as my vehicle gets older and thus costs more, notwithstanding putting the wrong fuel in, that Im now on the wrong system. Im changing this year, particularly as Im reinvesting in a new wagon within the next few months.
