Buying a used car in Louisiana means more paperwork than most states because the bill of sale must be notarized — there is no shortcut. Use Form DPSMV2392 or a notarized equivalent, capture VIN and odometer accurately (federal law requires odometer disclosure on vehicles under 10 years old), and bring the notarized bill of sale, signed title, and Form DPSMV1799 to OMV within 40 days. Sales tax runs 4.45% state plus parish add-on. Run a VIN check before money changes hands — Louisiana flooded vehicles from Katrina, Ida, and other hurricanes have a habit of showing up with washed titles, and a notarized bill of sale won't protect you from a salvage rebuild you didn't know about.

Louisiana Used Car Bill of Sale — What You Need to Know
For any used car under 10 model years old, federal law requires an odometer disclosure on the title or on a separate odometer statement. Louisiana additionally requires the bill of sale itself to be notarized — both parties sign before a notary. Seller assigns the Louisiana title to the buyer; buyer files DPSMV1799 with the notarized bill of sale at OMV within 40 days.
Inspection
Not required
Sales Tax Details
4.45% Louisiana state sales tax plus parish/local add-on (combined typically 8–11%). For used cars, OMV calculates tax on the actual purchase price shown on the notarized bill of sale — but if the price is unreasonably low compared to NADA/Kelley Blue Book, OMV may reassess at fair market value.
Exemption: Immediate family transfers (spouse, parent, child, sibling) exempt with notarized family affidavit. Trade-in credit reduces taxable amount when used cars are bought from a Louisiana licensed dealer (private-party sales do not get trade-in credit).
Inspection Requirements
No statewide safety inspection required as of 2025 — Louisiana eliminated the annual sticker. No statewide emissions testing. Used cars from out of state must still pass a VIN inspection (visual VIN verification by OMV staff or law enforcement) when first titled in Louisiana.
Registration
Registration for this vehicle type is handled by Louisiana Office of Motor Vehicles (LA OMV) — not the same agency that handles cars in Louisiana. Plan for separate filings.
Louisiana Used Car Sale — Step-by-Step Checklist
Run a VIN history check (NMVTIS, Carfax, AutoCheck) — flood and salvage history is a real Louisiana risk.
Verify the title is a clean Louisiana title (not salvage, flood, or rebuilt) before signing.
Use Form DPSMV2392 — sign before a Louisiana notary public with the seller present.
Record VIN, year/make/model, exact odometer reading, sale price, and date.
Complete federal odometer disclosure for vehicles under 10 model years old.
Seller assigns the Louisiana title; buyer files DPSMV1799 at OMV within 40 days.
Pay 4.45% state sales tax plus parish add-on (8–11% combined).
Obtain Louisiana liability insurance (15/30/25 minimum) before driving.
Common Pitfalls
Skipping notarization — OMV will reject the bill of sale and refuse to process the title.
Buying a flood vehicle — Louisiana has high flood-title fraud risk; always run NMVTIS.
Underreporting the sale price — OMV cross-checks against NADA values and may reassess.
Missing the 40-day deadline triggers late penalties.
Forgetting parish sales tax on top of the 4.45% state rate.
Pro Tip
Notarize, run an NMVTIS check for flood history, and budget 4.45% + parish add-on for tax — flood-title fraud is the silent killer in Louisiana used car deals.
Louisiana Used Car Bill of Sale — FAQs
Why does Louisiana require notarization when most states don't?
Louisiana is a civil law state (a holdover from its French and Spanish legal heritage) rather than a common law state like the rest of the U.S. Civil law systems traditionally rely on notaries to authenticate transfers of property, and Louisiana extended that tradition to vehicle sales. The notarization requirement reduces title fraud and gives OMV third-party verification that both parties actually signed. Practically speaking it adds a $5–$10 step and 15 minutes at a bank, UPS Store, or notary public — annoying but enforceable. An unnotarized bill of sale will be rejected at the OMV window.
How can I check if a used car has a flood or salvage history?
Run the VIN through NMVTIS (National Motor Vehicle Title Information System) at vehiclehistory.gov — it pulls title data from all 50 states and is the gold standard for catching washed flood titles. Supplement with Carfax or AutoCheck for accident and service history. Louisiana has a higher-than-average flood-title fraud rate because of recurring hurricane damage (Katrina, Rita, Ida, Laura), and unscrupulous resellers move flooded vehicles to other states, retitle them clean, and sell them back into Louisiana. Inspect for water lines under carpets, rust on bolt heads under seats, and musty smells in the trunk and spare tire well.
Do I need a safety inspection on a used car in Louisiana?
No — Louisiana eliminated the statewide annual safety inspection sticker in 2025. You no longer need an inspection to title or register a used car bought from a private party. There is also no statewide emissions test. The only inspection that may apply is a one-time VIN verification when titling a vehicle that was previously titled in another state — OMV will visually confirm the VIN matches the title. For an in-state Louisiana-to-Louisiana private sale, no inspection step is required.
What if the seller and I can't meet at the same notary?
You can use two notaries with what's called a "split" or "remote" notarization — each party signs separately in front of their own Louisiana notary, who completes their respective acknowledgment. This is more cumbersome and some OMV clerks scrutinize split notarizations more carefully, so it's worth scheduling a single in-person notary appointment if at all possible. Louisiana also recognizes Remote Online Notarization (RON) under Act 86 of 2020 — both parties can appear via secure video before a Louisiana RON-commissioned notary. Always verify the RON notary is properly commissioned in Louisiana.
How does sales tax work on a used car bought from a private party?
Private-party used car sales are taxed the same as dealer sales at the OMV window: 4.45% state plus your parish add-on, totaling 8–11% combined. The taxable amount is the purchase price on the notarized bill of sale. Unlike dealer purchases, private-party sales do NOT get trade-in credit — you pay tax on the full purchase price even if you simultaneously sold your old car. OMV may compare your declared price to NADA Clean Retail or wholesale values and ask for documentation if your price is suspiciously low; bills of sale showing $500 for a 2020 Camry will get flagged and reassessed.
