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 internet-based auction connected to unpaid 2024 property taxes and related fees across the parish, including properties in Slidell. The sale gives registered bidders a chance to participate through the parish’s contracted auction system, while giving delinquent taxpayers one more urgent reminder to resolve outstanding balances before bidding begins. The annual process is tied to property tax collection, not a traditional real estate sale, which makes the details important for both property owners and prospective bidders.
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. Interested participants should complete registration ahead of the deadline because same-day registration is not the kind of last-minute option bidders can safely count on when a formal tax sale is involved.
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. That broad list means the sale may include a variety of residential, commercial and undeveloped properties, depending on which tax accounts remain unresolved before the auction date.
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. Those notices gave property owners multiple chances to review balances, contact the tax office, ask questions and make payment before their property appeared in the tax sale process.
Officials emphasized that the tax sale does not transfer the house or land itself. The sale involves a tax title tied to unpaid ad valorem taxes, interest, penalties and other collection costs, rather than a standard purchase of the physical property. Louisiana law gives property owners whose properties go to tax sale a three-year redemption period, allowing them to reclaim their property by paying the required amounts through the sheriff’s office.
Delinquent taxpayers are being urged by the sheriff’s office 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. That timing matters because payments may need processing before the sale list is updated. Property owners who wait too long could face added confusion, added costs or a more complicated redemption process after the tax sale takes place.
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 become familiar with the system before the live auction. That practice option can help new bidders understand how the platform works, how bids are entered and why Louisiana tax sale rules should be reviewed carefully before any money is committed.
Why This Matters In Slidell
St. Tammany Parish Sheriff’s Office property tax collection includes Slidell under contract, which means city properties can appear in the annual sale when taxes remain unpaid. Slidell homeowners, landlords and investors should treat the publication of the delinquent list as a serious deadline notice because payment before the cutoff can keep a property from moving into the sale. Buyers reviewing the auction should also understand that they are bidding on a tax title lien interest, not purchasing a move-in-ready home through a regular real estate transaction.
Slidell property owners may also feel the effects of a tax sale later during title work, refinancing, estate planning or a future property transaction. Tax sale records can create questions that need to be cleared before a property changes hands, especially when a redemption period is still active. The sheriff’s office advises anyone unfamiliar with Louisiana tax sale law to review the rules closely before participating, because the process carries legal and financial details that are very different from a typical home purchase.
