As a debut author, this filing season is the first year that this will be a consideration for me. I did some research on the net and found a few articles which I felt may be useful to someone else as well. Here they are:
How to File Income Taxes if You're a Professional Writer or Hobbyist
Death, Taxes and the Writer
Taxes and Finances for Writers
I hope this helps. Now I need to go sort out how to file mine based off of this information!
