The Wisconsin Legislature passed the legislation necessary to conform Wisconsin's sales and use tax laws to the requirements of the Streamlined Sales and Use Tax Agreement (SSUTA) as part of 2009 Wisconsin Acts 2 and 28. The conforming legislation, known as the Main Street Equity Act, became effective in Wisconsin on October 1, 2009.
Wisconsin petitioned the Streamlined Sales Tax Governing Board (SSTGB) for membership in the SSTGB as an associate member effective July 1, 2009, through September 30, 2009, and as a full member effective October 1, 2009. On May 12, 2009, the SSTGB voted unanimously to approve Wisconsin as an associate member of the SSTGB effective July 1, 2009 through September 30, 2009 and a full member of the SSTGB effective October 1, 2009.
As of August 1, 2020, there are 23 full member states (Arkansas, Georgia, Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Nebraska, Nevada, New Jersey, North Carolina, North Dakota, Ohio, Oklahoma, Rhode Island, South Dakota, Utah, Vermont, Washington, West Virginia, Wisconsin, and Wyoming) and 1 associate member state (Tennessee).
