The Caddo Parish tax sale is an annual online auction, typically held the first week of June through CivicSource, where investors buy tax lien certificates on properties with delinquent parish taxes. Starting in 2026, Louisiana replaced its old fractional-ownership bid-down with a true tax lien auction: you compete by lowering the monthly interest rate you’re willing to accept on the delinquent debt, and the lowest rate wins the certificate.
How the Interest Rate Bid-Down Works
The price of a certificate is fixed. It equals the face value of what the property owner owes: delinquent taxes, accrued interest, penalties, and advertising and recording costs. What varies is the monthly interest rate you’ll earn on that face value until the owner pays it off.
Bidding opens at a maximum of 1% per month and drops in one-tenth-of-a-percent increments. The floor is 0.7% per month; no bid below that can be accepted. If two bidders submit the same lowest rate, whoever bid first takes the certificate. If nobody bids at all, the certificate goes to the parish itself.1Louisiana State Legislature. Louisiana Revised Statutes 47:2154 – Tax Lien Auctions; Time of Auction; Price
The auction runs online with bidding opening no earlier than 8:00 a.m. and closing no later than 8:00 p.m. on a weekday. If the sale spans multiple days, bids can be placed any time on any lien where bidding hasn’t closed. Bids submitted before the auction officially opens are void.
The old system let bidders accept a smaller and smaller ownership share of the property in exchange for paying the full tax debt, which created messy fractional-title problems years down the road. Fractional ownership is gone under the new rules. You buy a lien, not a slice of the land.
Finding Properties Before the Sale
Before the auction, the tax collector sends written notices to delinquent owners and then publishes the consolidated delinquent tax list twice within thirty days in the official parish journal, which for Caddo Parish is The Times.2Louisiana State Legislature. Louisiana Revised Statutes 47:2153 – Notice of Delinquency; Tax Lien Holder; Tax Lien Auction The same listings appear online at CivicSource.3Caddo Parish Sheriff’s Office. Taxes FAQ
Each listing gives the legal description of the property, the owner of record, and the total amount owed. The listing won’t tell you about existing mortgages, environmental problems, or whether the house is standing. Pull title research on any parcel you’re seriously considering. The face value you’ll pay doesn’t change based on condition, but your odds of ever collecting do.
Registering to Bid
Anyone can register through CivicSource. You’ll submit an IRS Form W-9 so the tax collector can report interest income, along with your full legal name, Social Security number or employer identification number, and current contact information.3Caddo Parish Sheriff’s Office. Taxes FAQ
Set up a verified payment method well ahead of the sale, usually a linked bank account for ACH or proof of funds for wire transfer. Technical issues or unverified accounts on auction morning can lock you out, and there’s no grace period. Interest you earn is taxable; expect a Form 1099-INT from the tax collector by January 31 of the following year.
What You Actually Buy
A tax lien certificate is not a deed. It gives you no right to enter, occupy, rent, or sell the property. What you own is a legal claim against the property, secured by the parish mortgage records, that entitles you to be paid the termination price when the owner settles up.4Justia Law. Louisiana Revised Statutes 47:2155 – Tax Lien Certificate
The certificate records the proceedings, describes the property, and states the face value, your winning monthly interest rate, any penalty, and what you paid. It’s prima facie evidence that the lien is valid and belongs to you. Within thirty days of the auction, the tax collector files it in the parish mortgage records and sends you a certified copy.1Louisiana State Legislature.

How You Get Paid Back
The owner can clear the lien any time by paying the termination price to the tax collector. The components are:5Louisiana State Legislature. Louisiana Revised Statutes 47:2243 – Termination Price
- Face value of the certificate: delinquent taxes, interest, penalties, and costs rolled in at the time of sale.
- Penalty of up to 5% of the delinquent amount if the taxes stayed unpaid more than 90 days.6Justia Law. Louisiana Constitution Article VII – Revenue and Finance
- Interest at the rate you bid, between 0.7% and 1% per month, calculated on the face value and not compounded.
- Reasonable notice costs you incurred to send required post-auction notices, capped at $500.
- Any subsequent years’ taxes you paid on the same property to protect your lien, plus interest at your bid rate.
The tax collector won’t take a partial payment on a single certificate. If a property has multiple certificates from different years, the owner can pay them off one at a time, and payment goes to the oldest certificate first unless the owner directs otherwise.
Enforcing the Lien if the Owner Never Pays
If the termination price goes unpaid for three years after the certificate is recorded, you can file suit to enforce the lien through seizure and sale of the property. Before filing, you must send notice to all tax sale parties, including the former owner and anyone with a recorded interest, at least 180 days ahead of filing. That notice has to warn them that enforcement is coming and state the current termination price.7Louisiana State Legislature. Louisiana Revised Statutes 47:2156 – Tax Lien Certificate; Post-Auction Notice
Even after suit is filed, the owner gets one last 30-day window after being served to pay the full debt plus your court costs and attorney fees and walk away with the property. And there’s a hard cutoff on your end: enforcement must be filed within seven years of the certificate’s recordation, or the lien lapses entirely. Sitting on a certificate too long means losing your investment.
If enforcement actually transfers the property to you, you still don’t have marketable title. You’ll need to file a quiet title action in the district court for the parish where the property sits. The petition describes the property, identifies the original sale, references the recorded certificate, and notifies all parties that their interests end unless they challenge within six months of service. If a party is a nonresident, missing, or has an unknown address, the court appoints a curator to represent them.8Justia Law. Louisiana Revised Statutes 47:2266 – Procedure to Quiet Tax Titles
Once six months pass with no challenge, the court renders judgment confirming your title. Only then can you record the deed and shop for title insurance. Most insurers won’t touch a tax-sale title without that judgment.
Risks That Can Undo the Investment
Two situations can disrupt an otherwise clean lien.
First, federal tax liens. If the IRS has a recorded lien against the property, the local property tax lien generally takes priority, but the United States keeps a redemption right of 120 days from the date of sale or the state-law period, whichever is longer.9Office of the Law Revision Counsel. 28 USC 2410 – Actions Affecting Property on Which United States Has Lien In Louisiana, the three-year enforcement period controls. The IRS can step in and redeem by paying what you paid plus interest, cutting short the stream of interest income you expected. Spotting a federal lien in the mortgage records before you bid is the only way to avoid that surprise.
Second, bankruptcy. If the property owner files for bankruptcy, the federal automatic stay halts most collection actions, including enforcement of your lien.10Office of the Law Revision Counsel. 11 USC 362 – Automatic Stay Enforcement actions taken in violation of the stay can be voided even if you didn’t know about the filing. If you discover the owner has filed, talk to an attorney before doing anything else; you may need relief from the bankruptcy court before you can proceed.
Costs to Plan For Beyond the Bid
The face value of the certificate is the beginning of the budget, not the end. If you’re prepared to go the distance toward ownership, plan for:
- Title research before bidding and again before filing enforcement, with costs depending on the complexity of the title history.
- Post-auction notice costs, recoverable up to $500 as part of the termination price.
- Attorney fees for enforcement and quiet title. The statute caps recoverable fees at the greater of 25% of the secured amount or $2,500, but your actual bill can exceed what you can recover.
- Court filing and deed recording fees, which should factor into your break-even math.
Most Caddo Parish lien investors earn their return when the owner pays the termination price inside the three-year window, and the interest income is the whole investment. Ending up with the property itself is a multi-year legal process with real costs that only plays out when an owner has genuinely walked away. Going in expecting a fast path to a deed sets you up for disappointment.
