I think they say you can claim it as marketing/advertising.
I think the whole process is nust to rob you and supposedly legal for them to do so

So work uniforms they say, you need to clothes to wear regardless. So not sure if any work wear for cleaning windows is a green light, other than advertising costs if your company name is on them.
What i dont understand is how politicians can claim wallpapering their homes as an expense and we cant claim clothes

Ild like to go through books of the taxman and/or politicians
