As the result of an Executive Order signed by Governor Dirk Kempthorne on July 29, 2005, Idaho officially supports the mission of the Streamlined Sales Tax Project, joining as a participating state. This action entitles Idaho to vote on issues before the SSTP and analyze and recommend sales tax simplifications cited in the SSTP Agreement (Executive Order No. 2005-09, Office of the Governor, signed July 29, 2005).
