<prompt> Human: Im just starting the process of writing a cookbook and am trying to reason out what could possibly be tax-deductible as a business expense? Im thinking that the food I buy specifically to try out recipes is a bulk of the expense, but there are also to the use of my personal computer, utilities, cooking equipment, etc. Anyone have any advice on this topic?In the end Im fine with paying everything upfront and hoping to sell the book, but if I can find a financial advantage in the meantime...all the better, you know?  <response>: Talk to an accountant.
