Effective July 26, 2003, the Wisconsin Legislature enacted a law relating to the collection of sales and use tax from suppliers doing business with the State of Wisconsin. The law provides that agencies and authorities cannot purchase any materials, supplies, equipment, or contractual services from suppliers, if the supplier and its affiliates are not registered, collecting, and remitting Wisconsin sales or use tax on sales of tangible personal property and taxable services in Wisconsin. This law does not change the federal constitutional limitations on who must be licensed to conduct business in Wisconsin.​ Information on how this law may impact you may be found here: ​​​​WI Department of Revenue Vendor Law​
