Hi. I am an american living in korea. I started to trade stocks on the korean market. Do i have to pay taxes? if how do i find out what tax bracket i am currently in? Also how does this tax system work? For instance do i have to pay taxes on every transaction i complete or is it on the yearly basis. For instance if i made 1$ on my profits after one year of constant trading would i pay taxes on the 1$ or would be it on every profitable trade that i made within that year? And what happens when im in the negative after the year would i still have to pay taxes on the profitable trades i made within the year?
