Wisconsin Voluntary Disclosure Program

​​The Wisconsin Department of Revenue encourages businesses and individuals who are not in compliance with Wisconsin tax laws to voluntarily come forward. Taxpayers may remain anonymous throughout the voluntary disclosure process.

Online Marketplace Sellers: Sellers who make sales through online marketplaces may be required to collect Wisconsin sales/use tax and file Wisconsin franchise/income tax returns as a result of having inventory stored in a warehouse or fulfillment center located in Wisconsin. Such sellers may participate in Wisconsin's Voluntary Disclosure Program. Marketplace providers that sell goods on behalf of sellers may also participate in Wisconsin's Voluntary Disclosure Program.
