... taxes for any income earned in Korea, but I do not pay the same income tax twice for the income tax filed in South Korea.
However my question is on the income earned on stocks. I'm about to start investing money on the "Korean" stock market as a private investor, and under the tax law in Korea, private investors in the stock market are "exempt" from paying taxes on the income earned from stocks. Now my questions is "Do I have to file and pay the income tax and report to the US IRS since I would be exempt from paying taxes in Korea?"

p.s. screw the tax laws
