You may pay your annual tax bill in two installments. The first installment is due November 1st and becomes delinquent if not paid at the County Tax Collector's Office by 5 p.m. on December 10th, or deposited in US mail prior to midnight on the delinquency date. You may pay the entire tax bill when the first installment payment is made.
The second installment is due February 1st and becomes delinquent if not paid at the County Tax Collector's Office by 5:00 p.m. on April 10th, or deposited in US mail prior to midnight on the delinquency date. The second installment cannot be accepted before the first installment.
If either December 10 or April 10 falls on a weekend or holiday, taxes are not delinquent until 5 p.m. the next business day.
Since supplemental tax bill are mailed throughout the year, they have various due and delinquent dates that are not the same as your annual tax bill.
