How it works
Property tax in Jefferson Parish is calculated by first determining market value and applying Louisiana’s assessment ratio to arrive at assessed value. Taxable value may then be reduced by applicable exemptions. A combined local property tax rate, reflecting parish, municipal, school, and other district millages, is applied to the taxable value. The applicable combined rate depends on the property’s ward and municipality.
Examples
Two properties with the same market value can produce different estimated taxes if they are located in different wards or municipalities within Jefferson Parish. Differences in combined millage rates or eligibility for exemptions can change the taxable value and the resulting estimate.
Limitations and important notes
The results generated by this calculator are intended as a general estimate only. Jefferson Parish uses ward-specific millage rates, and some areas include flat fees or special assessments that are not part of ad valorem millage. Exemptions such as the homestead exemption are owner- and parcel-specific. Actual tax bills may differ from this estimate.
