<prompt> Human: The title covers it all. Im mainly interested if I can deduct things like part of my internet, part of my power bill, etc.Also, if I buy something like a new office chair, can I deduct that too?Thanks everyone.  <response>: Yeah, but note this will go under unreimbursed employee expenses and therefore you must itemize and only expenses over 2 of your AGI are subtracted. Unless you are a statutory employee check box 13 of W-2, this is how it works - otherwise you can use Schedule C and theres no itemization or 2 limit.
