Municipalities must distribute tax bills no later than the third Monday in December, with payment due January 31.

$
Effective rate 1.29% = this county's median owner-occupied tax bill ($3,481, ACS 2022 5-year estimate) divided by the typical home value at the time ($269,968, 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.
