How to report ISO bargain element if I do not qualify for AMT this year?
Exercised ISO options in 2017. This created AMT adjustment and increased my overall tax liability in 2017. I sold the shares in 2018 (qualifying position). However, 2018 my AMT tax liability is lower than regular tax liability due to the AMT adjustment created by my the 2017 ISO adjustment. Therefore, I do not qualify for AMT this year.
How can I adjust my tax liability in 2018 to reflect the fact that I already paid taxes for the bargain element in my 2017 return?
