Statewide schedule — read this before you rely on it
The December 31 delinquency date is uniform, but parishes run their own notice, prepayment and installment practices. Most counties in this state follow these dates.
Taxes unpaid after December 31 are delinquent and accrue 1% per month simple interest, and the collector then notices a tax lien auction.
Parish tax collectors send notices in the fall after the millages are levied, and unpaid accounts move to the tax lien auction the following spring.

$
Effective rate 0.36% = this county's median owner-occupied tax bill ($577, ACS 2022 5-year estimate) divided by the typical home value at the time ($161,571, 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.
