do you pay taxes on stock revenues ?
 

if you do is it just like income tax?
less ? more ?

I assume you mean capital gains tax. You pay depending on how long you held the stock and your tax bracket I beleive.

Uh, should probably ask an accountant since 99% of gfy can't afford to buy stocks!

Well you'd better

weren't you just busted for taking credit of other designers work? People have no shame these days, they get caught scamming and business as usual. :helpme

In the US, short term capital gains are taxed as ordinary income (i.e. up to 35%, depending on your tax bracked, just like your salary would be taxed). As of 2003, long term capital gains are taxed at 15%, and most dividends are taxed at 15% (there are several factors with dividends). Capital gains are the profit you make when you sell a stock, short term gains are when you sell stocks within a year of purchasing them, and long term gains are for stocks you sell after more than a year of holding them.

5-15% percent for long term gains
(depending on your tax bracket)

short term gains are taxed at your normal tax rate
