These are the rules for a new car bought from a dealer. Used-car and private-sale rules can differ. How we check this data.

Louisiana charges 5% at the state level. State rate since January 1, 2025; parish and city taxes add more. That rate is higher than 16 states and lower than 29 states. County and city taxes may add to it, so check your local rate and enter the total in the calculator.

What to know in Louisiana

Louisiana's state rate on vehicles has been 5% since January 1, 2025, but the state share is often the smaller part of the bill. Parishes and cities add their own taxes, and local rates in Louisiana are high, so check the combined rate where you live.

Both your trade-in and any rebate reduce the taxable price, so a rebate is worth more here than in states that tax the price before rebates. The calculator takes the rebate off before it figures the tax.

Does Louisiana tax your trade-in?

No. Louisiana only taxes the difference between the new car's price and your trade-in. On a $35,000 car with a $10,000 trade-in, you'd pay $1,250.00 in state tax instead of $1,750.00, a saving of $500.00. That saving is worth counting when you compare a dealer's trade-in offer with selling the car yourself.

Example: a car loan in Louisiana

A $35,000 car with $5,000 down, $1,500 in fees, and a 60-month loan at 6.5% APR ($1,750.00 state tax, rolled into the loan):

Rebates and fees

In Louisiana, a rebate lowers the taxable price, and the calculator takes it off before figuring the tax. Title, registration and dealer documentation fees vary, so ask for an itemized out-the-door price and put the fee total in the calculator.
