We have converted to a new, modern assessment system: Arist, by Farragut.
We are proud that we now utilize and provide our citizens with this leading-edge, fully GIS-integrated system. This advancement in our technology has caused changes to our processes, procedures, and timing. The most important change is that ownership will now be reflected on the tax roll and tax bills as of July 1, 2023 with few exceptions.
We will provide additional updated information and instructions as available.
At the St. Tammany Parish Assessor’s Office, it is our goal with this site to provide you with valuable information in a format that is user-friendly. This site will continue to develop and we invite you to check back often as we add more content.
