i know tax season is about over and all but i am thinking of next year already. i just bought a new computer and i know that can be written off. but i am thinking of getting a new desk because right now my computer sits on an old coffe table and its killing my back!! will i be able to use that as a write off? i would say about 75-80% of my time on my computer is used for business purposes. i wasnt sure about that one since its not 100% used for business. thanks!!
