2019 Wis. Act 10 clarifies that a marketplace provider is required to collect and remit sales or use tax for all sales of taxable products and services in Wisconsin that the marketplace provider facilitates on behalf of a marketplace seller, as provided in secs. 77.52(3m)(a) and 77.523(1), Wis. Stats.

The Act also reverses the effect of the decision in Orbitz, LLC vs. Wisconsin Department of Revenue, (Wisconsin Court of Appeals, District IV, February 11, 2016) by requiring marketplace providers that facilitate sales of all services under sec. 77.52(2), Wis. Stats., including lodging services, to collect and remit sales or use tax on the entire amount charged to a purchaser, as provided in sec. 77.52(3m)(a), Wis. Stats.

Note: For sales made prior to January 1, 2020, both the marketplace and third-party seller may be liable on taxable sales. See the article titled "Online Marketplace Sellers are Liable for Wisconsin Tax on Third-party Sales" in Wisconsin Tax Bulletin 192 (January 2016) for additional information.
