Louisiana Title Transfer in a Private Sale: Notary, 40 Days, $68.50 Title

Louisiana still wants the seller's signature on a private-sale title witnessed, either by a notary or by two witnesses who fill in the title's Acknowledgement of Witness section. You then file form DPSMV 1799 with the Office of Motor Vehicles (OMV) or a public tag agent and pay sales tax by the 40th day after the sale, along with a $68.50 title fee, an $8 handling fee, up to $6 in local fees and a plate fee based on the car's value. Miss day 40 and penalty and interest start stacking on the tax.

I read OMV's public pages and two of its internal policy documents on October 16, 2026, and they do not say quite the same thing. The Used Title and Registration page says the title must be "assigned before a notary." OMV Policy 2.00, which shows a revision date of July 30, 2026, allows the two-witness option for sales between private parties. If the seller is local and willing, the notary route is the safer one at the counter.

Signing the title the way OMV accepts it

Policy 2.00 spells out the witness rule in detail. The seller signs in front of a notary, or in front of two witnesses, and a two-witness assignment is rejected unless the Acknowledgement of Witness section on the title is completed by one of those same two witnesses. A stranger filling it in later gets the file bounced. Dealer sales stopped needing notarization on January 1, 2023, which is why friends who bought from a lot may tell you the notary is gone. For private sales it is not.

You do not need a separate bill of sale if the selling price is written in the title assignment. If the title has no odometer disclosure on the back and the car is not exempt, add a separate odometer statement. A lien on the title needs a proper release. And an act of donation, if a relative is giving you the car, must be signed before two witnesses and a notary.

What you bring and what it costs

For the title you need the completed DPSMV 1799 and the assigned title. For a plate, add a copy of your photo ID and proof of Louisiana liability insurance. OMV's fee table lists the title at $68.50, the handling fee at $8, lien recording at $15 with a UCC-1 or $10 with another security agreement, and the local fee "may apply and will not exceed $6." Car plates are 0.1 percent of the vehicle's value per year, figured on at least $10,000 and sold in two-year blocks, so the floor is $20. A $15,000 car falls in the $14,500 to $15,499 bracket and pays $30.

Public tag agents save you the OMV line, but OMV says they can charge a convenience fee of up to $23 per transaction under R.S. 47:532.1. That is legal and it is on top of everything else, so ask for the total before they start typing.

Sales tax and the 40-day deadline

Louisiana charges sales tax on private vehicle sales, figured on the price minus any qualifying trade-in and rebate, at a rate set by where you live. The Louisiana Department of Revenue's rate FAQ shows the state sales tax at 5 percent since January 1, 2025, up from 4.45 percent and set to run through December 31, 2029. Parish and city rates come on top, and they swing a lot. Look up your exact combined rate in OMV's parish tax table before you go, because I am not going to guess at yours.

If the 5 percent state rate applies to your purchase, a $15,000 car owes $750 in state tax. Add $68.50, $8, up to $6 and the $30 plate and you are at about $862.50 before parish tax and any tag agent fee. Our used car sales tax post walks through how other states figure this.

The deadline is the part that costs people real money. OMV Policy 55.00 says vehicle sales tax is due by the 40th day after the sale. If that day falls on a weekend or holiday, the last business day before it is the deadline, which is the opposite of how most states count. Penalty runs 5 percent of the tax for each 30 days late, capped at 25 percent, and interest for sales since January 1, 2023 is 1.25 percent a month on state tax and 1 percent on parish and city tax. On $750 of state tax, paying 60 days past the deadline means a $75 penalty before interest.

What the seller should do

The seller can file OMV's Notice of Vehicle Transfer online, which flags their record right away. OMV is clear that ownership does not legally move until you apply for the title, so the notice protects the seller but does nothing for you. If they are canceling their plate, OMV's cancel-plate page says to do it before dropping insurance.

Flood risk deserves its own step

Louisiana has had enough storms that a car with silt under the carpet and a fresh title from another state is a real possibility, not a story. Read our Louisiana flood and salvage used cars guide, and the Louisiana salvage and rebuilt title rules if the title carries a brand. Match the VIN on the car to the paperwork with our VIN verification steps, then search NMVTIS for brands.

Pull a history report yourself instead of trusting the seller's printout. CarVins sells CARFAX and AutoCheck reports as a licensed reseller and has no affiliation with CARFAX, AutoCheck or Experian. In mid October 2026 we are seeing roughly $5.50 for a guest report, $4.50 for members and $6.75 for both brands together, against $39.99 to $44.99 at retail; the checkout page has the real figure. CARFAX explains its report sections here.
