What happens to my incentive stock options if my company is sold?

Subject: Tax withholding on ISO’s
Date: Wed, 16 Feb 2000
In the event that my employer (NYSE listed company) is acquired, resulting in immediate 100% vesting of my incentive stock options as of the closing date of the acquisition- and cash is received for these options (excess of purchase price over option exercise price)- what tax, if any, is my employer required to withhold? Obviously I would prefer zero withholding and payment of tax in April, 2001 so long as I avoid underpayment penalty.
This is a controversial issue.
Most employers have been treating this as a “withholding optional” event.
However, the IRS has recently indicated that employers should be withholding for the ordinary income from Incentive Stock Options and Employee Stock Purchase Plans like they do from NQO exercises.
However, the IRS indicated in Treasury Notice 2001-14 that no penalties will be imposed when an employer does not withhold taxes for ISOs or ESPPs exercised before January 1, 2003.
Be sure you have adequate withholding and estimated tax payments to avoid the penalty for underpayment of estimated tax.
