If you are accessing your bank's on-line bill pay service to pay your real estate taxes, please make sure you set up a separate "bill payment" to the City of Fitchburg TREASURER (vs. Fitchburg Utilities) and indicate your bill number (the 7 digit number on the top right corner of your tax bill which begins with 225). Failure to follow these guidelines could result in an error with your payment being rejected AND up to a 10 day delay in receiving the money back into your bank account.
