I'm retired now, but I used to have a home office. I wrote off everything that I bought for the office, including a computer, printer, phones, business-related books, various publications, and even a small sound system for the office. This was legit, as this space was designed as, and only used as, a "home office." If it were ever questioned in an audit, there is no question that it would have passed muster. Take pictures of your workspace just in case, as Ceasar, if you are audited, will want to see proof of anything you claim on your annual financial confession.
