Just a quick one. I've just been filling in a claim form, not military but MoD, which has been sent out as an Excel Spread sheet. Down at the bottom is a box to enter your tax rate. My understanding has always been that MMA is tax free on the basis that it is an expense and you've already paid tax on the money you used to pay for the fuel. The tax rate box on the form is below all of the claim and so deducts from the MMA as well as the rest. Is this right or not? Thanks.
