For taxable years beginning in 2007, Wisconsin generally follows the Internal Revenue Code enacted as of December 31, 2006. Unless later adopted by the Wisconsin Legislature, changes to federal law enacted after December 31, 2006, do not apply for Wisconsin. Taxpayers must use 2007 Wisconsin Schedule I to adjust for Wisconsin and federal differences in the definition of the Internal Revenue Code. Schedule I provides a listing of the various items that must be adjusted.
