Who sends the property tax bill in Brown County, and how do you pay it?
The bill comes from the Brown County Treasurer. The value it is based on is set by a separate office, the assessor for your city, village or town (each municipality in Brown 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.
In Brown County the tax bill comes from two collectors: the first installment or full payment goes to your city, village or town (in the City of Green Bay, the city clerk's office collects in person from December 10 to January 31), and the second installment and any late taxes go to the Brown County Treasurer. Where to pay depends on your municipality and the time of year, so check the payment address on your bill. The bill covers school, municipal, county and technical college taxes together, less the state school levy and lottery credits. Online payments run through the county's payment portal, operated by an outside processor that charges a transaction fee; the county's instructions list an electronic check as the lowest-fee option. The county does not mail receipts for online payments.
