An unpaid first half accrues 1% monthly interest from March 1, and any balance unpaid after June 15 becomes delinquent on June 16 and can be sold as a tax lien.
County treasurers mail tax statements as soon as practicable after January 1.

$
Effective rate 0.21% = this county's median owner-occupied tax bill ($1,586, ACS 2022 5-year estimate) divided by the typical home value at the time ($739,218, 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.
