<prompt> Human: Help please taxes are weird I dont understand themedit: Thanks for all the help everyone! To clarify, most of my expense would be high quality dual monitors. The computer would be used for GIS work, programming, and some cartography. I havent actually priced out what I need yet, but Im guessing it will be in the 1200 dollar range.  <response>: Remember tax write-offs only count against income, so yes, you would have to write it off in the same year as your income from the job. Also, its not a one-time write-off, as with any other real property it is depreciated over time so you only get to write off a certain amount every year.
