Taxes are due when the bill is received and delinquent February 1; taxing units may adopt split payment (half by December 1, rest by July 1), and homestead owners 65 or older or disabled may pay in four installments.
Statewide schedule — read this before you rely on it
The February 1 delinquency date is uniform, but taxing units differ on adopting split payments, discounts, and late-bill postponements. Most counties in this state follow these dates.
A delinquent tax incurs a 6% penalty in the first month, rising to 12% on July 1, plus 1% interest per month until paid.
Tax bills must be mailed by October 1 or as soon afterward as practicable, and taxes are delinquent if not paid before February 1.

$
Effective rate 1.20% = this county's median owner-occupied tax bill ($2,677, ACS 2022 5-year estimate) divided by the typical home value at the time ($223,236, Zillow, 2022-12-31). Exemptions the seller holds — homestead, senior, veteran — usually do not transfer with the deed, so a new purchase can run above this figure. The county assessor sets the assessed value; this is an estimate, not a quote.
