Can I, as a fiction writer, deduct my magazine submission fees from my taxes?

[LeeM]

Yes, as long as it is not a hobby, (meaning that you are earning or attempting to earn a profit) you can deduct those submission fees and other business expenses from your fiction writer income on your personal tax return on Schedule C.
