We recently transferred millions of data items accumulated over the last 40+ years into our new, modern assessment system as part of our data transfer and software conversion which went live this August. We expect some normal issues with the learning curve, installation and training. Consequently, checking your assessment is now 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 was 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).

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: www.stpao.org/forms/

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.

Prior year’s certified millage rates were used to estimate taxes due until all the current year’s millage rates are approved by the Louisiana Legislative Auditor. Our annual deadline for submission is August 1. This year the millage rates were not approved until mid-September, as several taxing bodies were late submitting millage information to our office.
