By "local" are you referring to state taxes? If so, then of course I pay state taxes. Your entire gross personal income, including capital gains, is taxed by the sate.
Everybody pays "School Taxes", if you file State/Local return genius. Just because you never graduated from High School certainly does not exempt you from paying!
if you are unemployed and all of your income come from trading-you are exempt from school taxes. dont remember form number, but can find out later. those are part of property taxes(which also local) and you are talking about state. http://www.buckinghampa.org/events/Tax primer.htm
