Statewide schedule — read this before you rely on it
All 77 counties use the November 1 due date with half due by January 1 and the balance by April 1; the first half can slip later only where the roll is certified late. Most counties in this state follow these dates.
Delinquent ad valorem taxes bear interest of 1.5% a month or major fraction of a month until paid, capped at 100% of the unpaid tax.
County treasurers mail statements after the assessor certifies the tax roll in the fall, and collection opens November 1.
