The Department of Revenue has an online application that allows taxpayers and tax practitioners to verify estimated tax payments when completing a tax return. This application is available at revenue.wi.gov/Pages/apps/taxpaymentinquiry.aspx. It is available seven days a week, 365 days a year. If you experience problems when using this application, please contact the department at (608) 266-2772 so that we are made aware of the problem and can get it resolved. (If you experience problems outside of the department's regular office hours, please contact us as soon as possible during regular office hours, 7:45 am – 4:30 pm, Monday through Friday.)
