How do I know if a property is receiving an ad valorem property tax exemption or abatement?

Properties in St. Tammany Parish that participate in any Tax Exemption or Tax Abatement programs or assessments with a non-profit status provided by state law are indicated as such on their assessment on our “Check Your Assessment” page at STPAO.org: “Per LA state law, this assessment is Tax Exempt”. *Additionally, any notation of “taxes due” is NOT an actual dollar amount of taxes payable, but an ESTIMATE of what taxes would be payable if the property was not tax exempt under state law.
