How is the tax worksheet calculated?
We have added the commissions you have paid to your cost basis and subtracted commissions and SEC fees from your proceeds. In addition to the tax worksheet you may also need records of any relevant transactions that occurred prior to this tax year or in another account, or for corporate actions that involved symbol changes. Most exercises and assignments should be reflected, but stock acquired or sold through exercises or assignments is not updated with the option trade information. For additional information please consult a tax advisor.
