2025 parish millage rates, breakdowns, and comparisons can be viewed HERE. 2026 millage rates will be available in the fall of 2026, after they are approved by various boards and the Louisiana Legislative Auditor.
The 2025 tax roll was certified in October 2025. Any additions, deletions, or changes made to the 2025 Tax Roll as a result of an Assessment Review after the Tax Roll was certified in October will be reflected by “change orders” approved by the Louisiana Tax Commission. Any changes will be shown online in August 2026, when the tax roll is open for public inspection. This process occurs yearly.
GIS parcels reflect current/live configuration, underlying data reflects 2025 certified tax roll without subsequent change orders filed until the 2026 tax roll is certified.
Everything we do at the Assessor’s Office is done by LAW. Data used to assess property for the 2024 reassessment is from the LEGALLY DESIGNATED time period between July 1, 2022, and June 30, 2023. This is required by the LA Tax Commission.
There is a lot of misinformation being shared currently on social media that demonstrates a lack of knowledge and understanding of the taxing process and the Assessor’s role in it. To educate yourself with FACTUAL information about millages and how your taxes increase click HERE.
When searching by property address, don’t use address suffixes, such as “street” or “drive” or “road” for better results.
