City of Beloit Taxpayers Only

If paying your Real Estate Taxes by mail, make your check payable to the Rock County Treasurer, P.O. Box 1508, Janesville, WI  53547.  Include your tax parcel number with your payment or indicate on the check or money order what parcel number you are paying. If you are paying on multiple parcels please indicate the amount you are paying on each parcel.  Also include a self addressed stamped envelope if you are requesting a receipt.

If paying in person we are located on the second floor in the Rock County Court House, 51 South Main Street, Janesville.  The County Treasurer’s office is open from 8:00 a.m. to 5:00 p.m.  Due to the recent influx of counterfeit money in the area, the County Treasurer is asking taxpayers to pay by check or money order.  Staff will be examining all currency, which can be quite time consuming.
