Please help, I’ve been talking with our HR waste of space manager and I’m really confused.
My usual place of work is an office about 40 miles from home, but I’m often required to visit clients premises’ (the cost of which is charged to the client).
If I drive straight from home to a client's site I’ve been instructed to charge the full mileage from the office (use route finder to work it out).
In an instance where I drive past the office I’d charege the mileage I do from the office to site and back and pay the equivalent of my commute myself, however If I drive away from the office I’ll only drive the distance from home to site and back but have been instructed to charge the mileage from the office, so I’m charging for 80 miles that I’ve not driven, which seems a bit fraudulent to me!?
HR claimed that it’s all to do with HMRC and tax, but haven’t really explained it and I still don’t really know what I should be doing, I don’t want to be left out of pocket, but also don’t want to be doing anything that could come back and bite me on the arse, please help.
