Slidell Properties Included in St. Tammany Tax Sale

Sheriff’s Office Says Online Bidding For Delinquent 2024 Property Taxes Is Scheduled For July 29

The St. Tammany Parish Sheriff’s Office has opened registration for its annual property tax sale, an online auction tied to unpaid 2024 property taxes and related fees across the parish, including properties in Slidell.

According to the sheriff’s office, the sale is scheduled for July 29 and will run online from 8 a.m. to 4 p.m. through the parish’s contracted auction platform. Registration for bidders opened June 25 at 8 a.m. and is set to close July 18 at 4 p.m.

The sheriff’s office said about 1,690 properties are included in the first published delinquent list for the 2024 tax year. The list covers properties with taxes and or related fees owed to the parish and to the municipalities of Slidell, Mandeville, Covington, Pearl River, Abita Springs and Madisonville.

The office said property tax bills for 2024 were mailed on Nov. 18, 2024. Delinquent notices were later sent on Feb. 3, 2025, and again on May 27, 2025.

Officials emphasized that the tax sale does not transfer the house or land itself. Instead, what is sold is a tax title tied to the unpaid ad valorem taxes, interest, penalties and other collection costs. Under Louisiana law, property owners whose properties go to tax sale still have a three-year redemption period to reclaim their property by paying the required amounts through the sheriff’s office.

The sheriff’s office is urging delinquent taxpayers to make payments by noon on July 28 so payments can be recorded and affected properties can be removed before bidding begins the next day.

People interested in bidding must register online in advance. The sheriff’s office said registrants will also have access to a Louisiana-specific practice sale to help them get familiar with the system before the live auction.

Why This Matters In Slidell

Because the sheriff’s office collects property taxes for Slidell under contract, city properties can appear in the annual sale when taxes remain unpaid. For Slidell homeowners, landlords and investors, the publication of the delinquent list is an important deadline signal: paying before the cutoff can keep a property from going into the sale, while buyers looking at the auction should understand they are bidding on a tax title lien interest, not buying a move-in-ready home through a standard real estate sale.

The process can also affect title work and future property transactions, which is why the sheriff’s office advises anyone unfamiliar with Louisiana tax sale law to review the rules carefully before participating.
