How Jefferson Parish property tax is calculated

Jefferson Parish property tax is based on the taxable assessment and the tax rate. The tax is calculated by multiplying the taxable assessment by the applicable millage rate.

The Assessor’s property tax estimate page explains the basic calculation. For residential property, the example starts with market value, applies 10% to find assessed value, subtracts a $7,500 assessed-value homestead exemption deduction when applicable, and then applies the ward millage rate.

Millage varies by ward and municipality. The Assessor’s 2025 millage and wards page lists parish, city, and total millage rates for Jefferson Parish wards.

Homestead exemption and special assessment

The Jefferson Parish Assessor’s Office handles homestead exemption. Louisiana’s homestead exemption applies to the first $7,500 of assessed value on an owner-occupied home. Only one homestead exemption in Louisiana can be granted on a home owned and permanently occupied as a domicile.

To file, the property owner must appear in person at either Assessor office location. Bring a recorded copy of the act of sale and photo identification showing the property address. If a husband and wife own the property jointly, only one must appear in person.

The Assessor also provides information about the special assessment level for qualifying seniors, certain homeowners with disabilities, and qualifying surviving spouses. The special assessment level freezes assessed value, not the tax rate.

Use the Assessor’s homestead exemption information for exemption details and the seniors and special assessment page for assessment freeze guidance.

Assessment appeals and forms

If the assessed value seems high, contact the Jefferson Parish Assessor’s Office. Assessment disputes are handled during the 15-day books-open period, and the taxpayer should provide documentation supporting the claimed value.

The Assessor provides printable forms for address changes, residential property, vacant land, apartments, commercial property, business personal property, watercraft, and appeal forms. The Assessor forms page is the starting point for these printable forms.
