Chaps, Allow me to share with you a tip regarding tax relief on work-related travel that has just earned me a Â£2600 tax rebate and could have earned me a lot more had I known about it earlier. HM Revenue and Customs allow everyone (including the Armed Forces) to claim tax relief for work-related travel (and other expenses incurred due to work). However, they don't usually allow you to claim tax relief on travel from home to your place of work (what they call "ordinary commuting"). However, if you get a posting of 24 months or less, HMR&C consider this to be a "temporary workplace" and allow you to claim relief at your highest income tax rate for travel from home to that temporary workplace (because it is no longer defined as "ordinary commuting"). Please note, it must be 24 months or less from the outset. It isn't a "temporary workplace" if your posting was 3 years for example and gets cut to 24 months or less. HM R&C allow relief at a rate of 40 p per mile for the first 10000 miles and 25p per mile for the remainder. You must subtract any allowance that work give you from those rates (RPOD, RILOR, GYH(D) or whatever). For example, I had a 1 year posting that involved a weekly commute of 400 miles so I did approx 18400 miles in that year. I got 15 p per mile RILOR. I claimed tax relief at 40-15=25 p per mile for the first 10000 miles and 25-15=10 p per mile on the remaining 8400 miles. Thus I claimed relief on (10000x.25) + (8400 x .1) =Â£3340 and got 40% of that back - Â£1336. You claim by filling in the amount you're claiming relief on (eg the Â£3340 from my example) in box 1.32 of the Employment Supplement of the Self-Assessment tax return. It helps if you show your working on the additional information page. You can do your SA return online and you get the money into your bank account within a matter of days. You can also claim back 5 years from the 31 Jan following the current assessment year, but you have to do that by letter to your tax office. It took a long time, but when the tax man eventually replied to my initial claim, he asked me if there was anything else I wanted to claim for! There was no quibbling and he accepted my calulations with no supporting evidence (they can of course ask for that later). I should point out that I'm not a tax advisor or an accountant so I suggest you get on the HM R&C website and read up on it for yourself. However, I know that I am Â£2600 better off simply for finding out about this (from a Crab would you believe!), then filling in a form and writing a letter. You know it makes sense!
