Is there a general rule for federal income tax withholding for ISOs exercised and sold for cash at the same time? Do you use the W-4 rate or the rate that applies for bonuses?

No federal income tax withholding is required for the disqualifying disposition of ISO shares. Section 251(a)(1) of the American Jobs Creation Act of 2004 “officially” repealed the withholding requirement, which was previously suspended by the IRS.
