In response to the pandemic, county policy is to encourage minimizing in-person customer contact where possible.  This is for the safety of both the customer and staff.

The public computers in the hallway are available for searches.  No genealogy searches until further notice.

Iowa County Real Estate Taxes

Option 1: PAY IN FULL to the municipal treasurer by January 31st.

Option 2: Pay the 1st installment to the municipal treasurer by January 31st and the second installment to the County Treasurer by July 31st.

Postponed taxes can be paid to the County Treasurer any time after January 31st but the last date for payment is July 31st. Iowa County has until February 20th to settle with all 29 municipalities for their collections, therefore we cannot issue a county tax receipt until after February 20th.

If your tax bill qualifies and if you choose to pay your taxes in installments, then you must pay each installment by the due date or the TOTAL amount of your remaining unpaid taxes, special assessments, special charges and special taxes (if any) will be delinquent (S. 7411(7) or 74.12 & 74.85, Wis. Stats.) All delinquent taxes are subject to interest of 1% per month (fraction of a month counts as a whole month) from February 1st until paid, and in addition, may be subject to an additional penalty (S.74.47).

On September 1st of each year, a tax sale certificate number is assigned to each parcel with unpaid taxes. Two years from the tax certificate sale date, if the tax is still unpaid, the County can start action to take title to the property by tax deed.
