As a result of the South Dakota v Wayfair ruling, beginning Oct. 1, Wisconsin will require out-of-state sellers with no physical presence in Wisconsin to collect and remit Wisconsin sales or use tax on taxable products and services purchased in our state.
To help Wisconsin remote sellers and tax practitioners understand new standards based on Wayfair, the DOR has launched an online resource center with background on the ruling, information on sales and use tax registration and answers to common questions.
