Thanks a lot! I got a lot of useful info. However, my ISO is not regular ISO (or maybe it's not ISO at all). I was granted some stocks at a discounted price. I must actually pay money to buy those stocks at one month later in the same calender year. 50% of those stocks will be locked for 1 year, the other 50% will be locked for two year before I can sell them. If company's or my performance doesn't meet some requirements, those stocks will be taken back by company at the original discounted price. According to ISO requirements, I need to report Alternative Minimum Tax (AMT) for the year I excise it. I guess I will be charged some tax for this. How about if this stocks is finally taken back by company at the original discounted price? Thank you.
