Stock options exercised in 2015, paid AMT taxes on delta of strike price and market value for that year. Then I sold the stock options in 2017 and need to understand what amount I'm going to be taxed long term gains on based on the fact that I already paid AMT tax amount on 2015 taxes and I don't want to be double taxed on the same proceeds. The numbers here are strike price was .21 cents per share and exercised purchase when fair market value was $1.14 per share. So I paid AMT taxes on quantity of shares multiplied by .93 cents the delta between exercise price and market value. Then in 2017 I sold the shares for $2.84 per share and need to understand if my long term capital gains exposure is based on the delta of original .21 cents a share and $2.84 final sales price, or will it be the delta of $1.14 and $2.84?
