Since the few thoughts I have to add to Zero's post from yesterday all hit too close to home: taxes!*
Mostly a friendly reminder - if you itemize your deductions, don't forget to include "Research expenses of a college professor." <- that's the IRS so we're official.
Don't include: Commute, lunch with co-workers, or expenses to improve professional reputation.
Include any unreimbursed ordinary or necessary expenses: "An expense is ordinary if it is common and accepted in your trade, business, or profession. An expense is necessary if it is appropriate and helpful to your business. An expense does not have to be required to be considered necessary."
I figure that at least includes conference expenses and probably professional memberships.
