Whoops–I Didn’t Pay AMT On My ISOs Exercised Prior to 1/1/08. What Do I Do?

If you didn’t pay alternative minimum tax on your incentive stock option exercises prior to January 1, 2008, and you owe the IRS a bunch of money–don’t worry about it.

The Internal Revenue Code now provides that any “underpayment of tax outstanding on the date of the enactment of this subsection which is attributable to the application of section 56(b)(3) for any taxable year ending before January 1, 2008, and any interest or penalty with respect to such underpayment which is outstanding on such date of enactment, is hereby abated.”

Section 56(b)(3) is the provision which provides that the gain on the exercise of incentive stock options is an alternative minimum tax adjustment. So, the Code now says, quite literally, that if you owe taxes attributable to the exercise of incentive stock options for a tax year ending before January 1, 2008, and interest and penalties on such taxes, you don’t have to worry about it!

Taxpayers should be aware that the provision is only effective for ISO exercises prior to January 1, 2008, and does not extend into the future.
