A little birdie told me that serving members of the forces are entitled to tax relief on journeys that we make for duty purposes. The rationale behind this is (apparently) the fact that the governmental rate of fuel allowance is something like 40p per mile whereas we only get paid something like 8p per mile when we claim MMA or GYH etc. Because we are all on short tours, the taxman considers daily or weekend commuting reasonable expense. So the story goes that we can claim tax back to the equivalent of the different between the two sums. A bit convoluted I know. So, for example, if I commute 100 miles a day and get GYH(P) of roughly 8p per mile, they give me Â£8. An MP or civil servant would get Â£40 (40p x 100 miles). And so I could claim reasonable tax refund of Â£32, based on the fact that I am a public servant on temporary duty (or something like that). Those figures sound a bit mental but the chap I spoke to is now the proud possessor of a tax code with 4 digits rather than my piddling 500-odd one. Does anyone know any more about this? I promise this chap wasn't a Nigerian scammer!
