THE 2026 OFFICIAL PUBLIC EXPOSURE/REVIEW PERIOD WAS MONDAY, AUGUST 17, 2026, THROUGH MONDAY, AUGUST 31, 2026.
The deadline to file a 2026 Assessment Review with the St. Tammany Parish Assessor’s Office was the last day of the Public Inspection/Exposure/Review of the Tax Roll period, Monday, August 31, 2026.
You may check your assessment HERE.
Checking your assessment on this website is a public service and has no charge. We will never ask for credit card information or payment of any kind.
2026 Assessment Review Applications are available HERE. For efficiency and quicker response time, filing via the use of our electronic online forms is strongly encouraged.
Any Assessment Reviews and Appeals received after the legal deadline Monday, September 14, 2026, forfeit any rights to appeal and are processed after all timely submitted reviews and Board of Review appeals are completed.
Any reviews filed after January 15, 2027, will be considered 2027 reviews.
The 2026 tax roll was certified on October 7, 2026. Any additions, deletions, or changes made to the 2026 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 2027, when the tax roll is open for public inspection. This process occurs yearly.
GIS parcels reflect current/live configuration, underlying data reflects 2026 certified tax roll without subsequent change orders filed until the 2027 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.
Do not wait until you receive your tax bill in November or until it is due December 31 to attempt to file an Assessment Review. All property owners are strongly encouraged to check assessments, verify mailing and physical addresses, and any special assessments, exemptions, etc., every year in AUGUST.
Storm Review Applications may be filed anytime there is a hurricane, flood, tornado, etc., regardless of normal deadlines.
Parish millage rates, breakdowns, and comparisons can be viewed HERE. Millage rates will be available in the fall, after they are approved by various boards and the Louisiana Legislative Auditor.
There is a lot of misinformation being shared 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.
