<prompt> Human: I work in the TVFilm industry and am paid via diffrent TV shows payroll services. I want to start shooting stock footage on the side to bring in additional money. So, if I am going on vacation, can I shoot stock footage on that vacation to upload to the stock websites for sale, then write off the trip on my personal taxes? What would I claim this as? How dangerous would this be? Thanks!  <response>: If your trip is primarily personal, you can only deduct additional expenses you incur for business. You cannot deduct any part of your plane ticket, hotel, etc, since you would have spent them anyway regardless of the business activity.
