Louisiana Car Sales Tax, Trade-In Credit, and Out-of-State Rules

What the desk and the buyer each need to know when a Louisiana deal crosses state lines: the rate, the trade-in math, the exemption paperwork, and the drive-home tags. Sourced facts link to the official publication; anything still being verified says so.

Short answer

Louisiana taxes vehicle sales at 5% state plus local add-ons (depends on location). Louisiana taxes the price after the trade-in is deducted. Louisiana gives only partial credit for tax paid to another state. Everything here assumes a retail purchase from a dealer, since most states treat leases and private-party sales differently.

Credit for tax paid to another stateLouisiana gives only partial credit for tax paid to another state. The credit runs rate-to-rate against Louisiana's state and local use tax, with proof of payment required. OMV's tax credit reference chart grants no credit for the listed states (Oregon is credited at only 0.5%), and no credit is allowed for ad valorem taxes paid elsewhere.

The fee is $5.50, the plate expires 30 days from issuance, and only one may be issued per vehicle.[6]
Out-of-state buyer registrationLouisiana OMV accepts a driver's license or ID card issued by another state as the vehicle owner's identification on a title and registration application, so an out-of-state-licensed owner can title and register a vehicle here. Sales and use tax is assessed at OMV based on the domicile of the vehicle, on the selling price less any qualifying trade-in and rebate.[7]

From the desk

Louisiana stacks parish rates on the state number and the combined figure moves more than almost anywhere. Quoting a deal without the parish rate is quoting wrong, and out-of-parish buyers make it a daily exercise.

Buying in Louisiana from out of state

If you live in another state and buy in Louisiana, the deciding rule is where the vehicle gets registered: your home state's tax applies at registration, whatever happens at the Louisiana sale. Louisiana gives only partial credit for tax paid to another state. The credit runs rate-to-rate against Louisiana's state and local use tax, with proof of payment required. OMV's tax credit reference chart grants no credit for the listed states (Oregon is credited at only 0.5%), and no credit is allowed for ad valorem taxes paid elsewhere. Exception: no full credit for tax paid to Alaska, Georgia, Iowa, Montana, Nevada, New Hampshire, New York, Vermont.[3]

Bordering states

Cross-border deals from Louisiana most often involve Arkansas, Mississippi and Texas. Each combination carries its own quirks; run the pair through the out-of-state checker.

Vehicle-type exceptions

Louisiana's motor vehicle sales tax applies to anything subject to the state's Vehicle Registration License Tax Law, so automobiles, trucks, motorcycles, motor homes, mobile homes, boat and utility trailers, campers and off-road vehicles are all covered by the same tax.[8]

Louisiana car sales tax questions

Louisiana taxes vehicle sales at 5% state plus local add-ons (depends on location). What that rate hits is the taxable price the desk computes, and trade-in treatment and doc fees decide that number.

Louisiana taxes the price after the trade-in is deducted. Since the treatment feeds straight into the taxable price, the same unit and the same trade tax out differently by state.

Louisiana gives only partial credit for tax paid to another state. The credit runs rate-to-rate against Louisiana's state and local use tax, with proof of payment required. OMV's tax credit reference chart grants no credit for the listed states (Oregon is credited at only 0.5%), and no credit is allowed for ad valorem taxes paid elsewhere. Exception: no full credit for tax paid to Alaska, Georgia, Iowa, Montana, Nevada, New Hampshire, New York, Vermont.

Louisiana caps dealer doc fees at $425. The doc fee is included in the taxable amount.

Start with the sale price and subtract the trade-in allowance (Louisiana credits it in full), then multiply by 5% state plus local add-ons (depends on location) plus any local add-on. The dealer doc fee is taxable in Louisiana, so add it before you multiply. The Louisiana calculator on this page runs those steps with the verified figures and shows the out-the-door estimate before title and registration fees.
