I am a brand new stock plan administrator for a company that went public six months ago. We are having an issue with taxes and same-day sales of ISOs. It is our policy to withhold taxes for all employees who exercise in a same-day sale for both ISOs and NQOs, unless the employee asks us not to for an ISO. What types of taxes are required to be withheld?

Your company should have a CPA firm that can answer these questions. NQOs are subject to income tax withholding and employment taxes (including social security, medicare and unemployment taxes) for the excess of the fair market value of the shares over the option price for vested shares. No withholding or payment of employment taxes are required when “qualified options”, including ISOs and ESPPs, are exercised. (The American Jobs Creation Act of 2004 resolved the issue of employment taxes for qualified options.)
