Pay or Log In to the Janesville Utility Bill Portal

Janesville municipal utility bills are quarterly and can include water, wastewater, stormwater, fire protection and sanitation charges. The online portal is useful for card/eCheck payments, but a mailed check or City Hall payment may avoid online convenience fees.

Start from the City’s Pay My Utility Bill Online page, then use the City’s “Take me to the Bill Pay page” button.

Find the account number on your bill

The City says you need your bill to find your account number before starting online payment. Do not guess the number from a bank bill-pay record unless it matches the current bill.

Check the payment fee

Online and in-person credit/debit card and eCheck fees are listed by the City. Debit/credit transactions are 2.5% with a $1.95 minimum service fee, and American Express is not accepted.

Save proof
