Statewide schedule — read this before you rely on it
Nearly every collecting unit uses the statutory September 14 and February 14 dates; a few city charters move the summer date slightly earlier or later. Most counties in this state follow these dates.
After the due date 1% monthly interest plus a 1% administration fee accrues, and tax still unpaid on February 28 is returned to the county treasurer as delinquent on March 1 with added fees.
The local treasurer mails summer bills around July 1 and winter bills around December 1.

$
Effective rate 0.94% = this county's median owner-occupied tax bill ($1,977, ACS 2022 5-year estimate) divided by the typical home value at the time ($210,488, 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.
