FAQ
What is the vehicle sales tax in Louisiana?
Louisiana charges a state-level rate of 4.45% on vehicle purchases. Local rates can add up to an additional 7.00%. Trade-in value is deductible from the taxable basis.
Does Louisiana give a trade-in tax credit?
Yes. In Louisiana, the value of your trade-in is subtracted from the purchase price before sales tax is calculated. On a $20,000 car with a $5,000 trade-in, you only pay tax on $15,000.
What is the title transfer fee in Louisiana?
Louisiana charges approximately $68.5 for title transfer. Dealer documentation ("doc") fees typically range up to $200, though these are dealer-set and negotiable on most transactions.
How do I calculate out-the-door price in Louisiana?
Out-the-door = purchase price + (taxable amount × effective rate) + title fee + registration. Taxable amount equals purchase price minus trade-in (where allowed). Effective rate is state plus local. Use the calculator above for an exact figure on your specific purchase.
