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.
Benefits of Voluntary Disclosure
- Written agreement to restrict the statute of limitations.
- Waiver of negligence penalties.
- Reduction of Interest from 18% to 12%, except for withholding taxes, motor vehicle floor taxes and intoxicating liquor floor taxes which remain at 18%.
- Possible reduction in number of periods for which returns must be filed.
- Elimination of the risk of being discovered under audit.
To be considered for voluntary disclosure treatment, a taxpayer must meet certain conditions and enter into a written agreement with the department. The following conditions must be met for a taxpayer to qualify for voluntary disclosure treatment.
- No tax returns filed for the period in question.
- No registration for the type of tax involved during the period in question.
- No contact by the department within the last 6 years regarding a registration/filing requirement or an assessment/audit assignment.
- Any partners of partnerships, shareholders in S corporations, trusts, or trust beneficiaries are considered to have been contacted if the pass-through entity has been contacted.
- Any owners of disregarded entities are considered to have been contacted if the disregarded entity has been contacted.
Note: The request for completion of nexus questionnaires by the department constitutes the commencement of an office audit.
Note: The department will not enter into an agreement to resolve a successor's liability under sec. Tax 11.91, Wis. Adm. Code, unless collection of the amount due from the predecessor appears unlikely.
