Who sends the property tax bill in St. Croix County, and how do you pay it?
The bill comes from the St. Croix County Treasurer (in 17 towns, villages and cities the local treasurer collects the full payment or first installment). The value it is based on is set by a separate office, the assessor for your town, village or city (each municipality in St. Croix County values its own properties; the county does not), which is who to ask if the value looks wrong. For how to look up and pay the bill, go to the county's own payment information.
St. Croix County's list of where to pay sends the full payment or first installment to the county treasurer in Hudson for 18 municipalities, and to the local treasurer in the other 17: the Towns of Baldwin, Cady, Cylon, Emerald, Erin Prairie, Glenwood, Hammond, Kinnickinnic, Pleasant Valley and Warren, the Villages of Hammond, North Hudson, Roberts, Spring Valley, Wilson and Woodville, and the City of Glenwood City. The second installment and any late taxes always go to the county treasurer. The county's payment page says that since 2025 every taxpayer can pay online, but its FAQ still says a first installment the county does not collect cannot be paid through the county's online system, so if your first installment goes to a local treasurer, ask that treasurer how to pay. Online payments run through an outside processor and cost $1.50 by e-check or 2.99% by card. The county mails a receipt only if you include a self-addressed, stamped envelope. A payment counts as on time only when the treasurer receives it, so mail it several days early.
