My uniform dry cleaning allowance is incorporated in my tax code. I found out that my tax code was different to my colleagues` and after discussion, I found out my code was incorrect. This was quite a few years ago but I spoke to the Tax Office, they sent me a self-assessment form, updated my code and refunded me something like £50 or £60 which was about 5 years` worth. There are no receipts or anything else involved, just an allowance in my tax code. Maybe it`s this system hammerman is referring to.
