Payment Deadlines
Installment Deadlines
You may pay your annual tax bill in two installments. The first installment is due November 1 and becomes delinquent at 5 p.m. on December 10; the second installment is due February 1 and becomes delinquent at 5 p.m. on April 10. You may, however, elect to pay the entire bill when you pay the first installment. A second installment payment will not be accepted unless the first installment has been paid.
Supplemental Bills
Supplemental bills have their own due dates and delinquent dates. All tax bills become delinquent after 5 p.m. of the delinquent date. Payments left at our office after 5 p.m. of the applicable date will be considered delinquent and returned for penalties.
Supplemental tax bills are mailed throughout the year and, therefore, may not be due or delinquent at the same time as your annual tax bill.
