2nd Installment Property Taxes Due July 31st

The second installment of property taxes are due by July 31st every year. Sometimes we find that residents are unsure about where and to whom that payment is made. Remember that Rock County coordinates the second installment collections; not the City.

There are two options to make those second installment payments:

• Mail their payments to the following address. Note that the Treasurer's Office accepts July 31st postmark as a timely payment.
  
  Rock County Treasurer
  PO Box 1975
  Janesville, WI 53547
  
  
• Pay in person at the Rock County Treasurer's Office located in the Rock County Courthouse at 51 S. Main Street, Janesville, WI. The Treasurer's office will NOT be open on Saturday, July 31st to collect tax payments.
  

If you have any questions feel free to contact City Hall at 868-6900 or the Rock County Treasurer's Office at 757-5670.
