​2007 Wisconsin Act 20 expanded individuals qualified for internet posting. On January 4, 2008 the delinquent taxpayer list was updated to include delinquent taxpayers who owe:

• More than $5,000, including tax, interest, penalty, fees, and costs, and
• The amount is unpaid more than 90 days after all appeal rights have expired

The department mails warning letters to new taxpayers meeting the above criteria for internet posting on a quarterly basis.

2009 Wisconsin Act 28 added a posting requirement for revoked sellers. Effective October 1, 2009, the Wisconsin Department of Revenue is required by sec. 73.03(64), Wis. Stats., to post information about delinquent taxpayers on the internet if they had a sellers permit revoked and have an outstanding delinquent balance.

The department does not post the accounts of taxpayers who:

• Entered into a valid payment plan,
• Submitted a complete Offer in Compromise, or
• Filed for bankruptcy
• In addition, revoked sellers who are out of business for at least one (1) year are removed from the revoked sellers internet page

If your name or the name of your business appears on the internet posting, the department strongly encourages you to:

• Pay the debt in full
• File missing tax returns that result in account adjustment to zero
• Provide proof of payment
• Enter into a valid payment plan
• Submit a complete Offer in Compromise
• Provide proof of bankruptcy

Making a partial payment, without entering into an approved payment plan, will not remove your name from the list. For more information contact us using the contact information listed at the bottom of this page.
