Wisconsin Department of Revenue

The Wisconsin Department of Revenue administers state tax collection, property tax oversight, and unclaimed property for Wisconsin. It serves individual taxpayers, businesses, tax preparers, and local governments across income, sales and use, withholding, excise, and corporate franchise taxes. Its online systems let filers submit returns, make payments, check refund status, register businesses for tax accounts, and respond to department notices. The agency also oversees state and local property tax administration, equalized values, and assessor certification, along with alcohol and tobacco enforcement. Additional functions include publishing tax forms, guidance, and statistics, and administering programs such as the homestead credit and lottery and gaming credit.
