As part of our new modern assessment system, we transferred millions of data items accumulated over the last 40+ years. Consequently, checking the data on your assessment this August is more important than ever.


The legal deadline to file a 2022 Assessment Review with the St. Tammany Parish Assessor’s Office was the last day of the Public Inspection of the Tax Roll period, Monday, Aug. 29, 2022 

If you filed a timely review with the Assessor’s Office and would like to Appeal to the Board of Review, (the St. Tammany Parish Council), the deadline to do so is Monday, Sept. 2, 2022.

*By law, you must first file a timely Assessment Review with the St. Tammany Parish Assessor’s Office before filing for an Appeal with the Parish Board of Review (the St. Tammany Parish Council).

IDA UPDATE: Property owners who received damage to their home or business and received a reduction as a result of Hurricane Ida may submit an Assessment Review Form for 2022 if repairs were not completed by Jan. 1, 2022. Property owners are encouraged to file as soon as possible. 

You can file a Storm Review Application anytime there is a hurricane, flood, tornado, etc., regardless of normal deadlines.

Applications to submit a 2022 Assessment Review form online are available here:

Forms may also be downloaded and printed from our website and are available at both of our office locations (appointments are recommended.)

If you need to update your address, please complete and submit a Change of Address Form.

Please do not wait until you receive your tax bill in November 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.

Any additions, deletions or changes made to the 2022 Tax Roll after it has been certified in October will be reflected by “change orders” approved by the LA Tax Commission and will not be visible online until the 2023 proposed Tax Roll is posted in August, 2023.

2021 parish millage rates, breakdowns and comparisons can be viewed here. 2022 millage rates will be available in the fall.
