The Wisconsin Department of Revenue has announced beginning October 1, 2018, Wisconsin will require out-of-state sellers with no physical presence in Wisconsin to collect and remit Wisconsin sales or use tax on sales of taxable products and services into the state. The Wisconsin Department of Revenue will develop rules consistent with the U.S. Supreme Court's recent decision in South Dakota v. Wayfair Inc., which approved a small seller exception for sellers who do not have annual sales of products and services into the state of more than $100,000 or 200 or more separate transactions. Any small seller exception adopted will not apply to sellers with a physical presence in Wisconsin.
