Thanks for the reply. This was stock options for a private company, which was acquired by a public company. The public company paid a certain amount per share, with 50% paid the first year, then 17% each year for 3 more years. We only received a 1099-B form from the firm that processed the payments, so I treated it like a regular long term capital gain the first time around. I mean, that's essentially what it is, right? There's no interest being paid on the remaining amount that is being paid out over the next 3 years, so it feels like each year is just a chunk of capital gains...
Assuming I really do need to use 6252 (sigh...), does this mean I need to go back and amend my previous tax return before I can proceed with this year's return?
