With tax time fast approaching...again, it's always nice to have resources at hand to make sure you are filing your taxes correctly, in a timely manner, and making the most use of allowable exemptions. I would personally recommend picking up the all inclusive book, Writer’s Pocket Tax Guide. It is an indispensable resource on the subject of writers and taxes.
If you'd rather search the web, here is a good starting point for tips on taxes for fiction writers.
