Tax payments must be received on or before the due date to avoid interest charges. If payment is not made within 30 days of the original date of mailing, the account will begin to accrue interest at the rate of 14% per annum, computed from the date the bill was due. A demand notice will be sent and a demand fee of $5 is charged against the account. If the account remains outstanding 14 days after the issuance of the demand notice, a warrant notice is sent. The warrant fee is $9. Please note that demand and warrant notices are sent only on the third and fourth quarter bills. If the account remains delinquent after June 30 of the fiscal year, a tax lien (a legal claim placed on property for debt) is placed on the property and is recorded with the Worcester County Registry of Deeds. In addition, the property is placed in the tax title system. A tax lien is the first step in the foreclosure process. All taxes, costs and interest must be paid to prevent foreclosure.
