I'm planning on buying two laptops, one for me and one for my partner. We both work together as self employed IM's, and so we both need a seperate laptop. At the moment we have zero, because our old ones have broken down. I was thinking of claiming the cost in my tax returns as being business expenses, so then I receive the amount back and essentially get the two laptops for free. What I want to know is whether this is possible and what kind of "proof" or information I need in order to do this? Do I need some sort of proof of income online? Has anyone else done this?
