Getting AMT Back: the Minimum Tax Credit

AMT caused by timing items like the ISO spread creates a minimum tax credit you carry forward (Form 8801). In a later year when your regular tax is above your tentative minimum tax — often the year you sell the shares — you can use the credit against the difference. It's real money back, but it can take years, and you need the cash for the AMT now.
