Louisiana state guide
Louisiana state and local vehicle tax
Louisiana applies 5% state sales/use tax plus local sales taxes. Motor vehicles, including isolated/private sales, remain taxable. Qualifying trade-in value reduces the taxable difference.
Title and registration
Title, plate and registration charges depend on Office of Motor Vehicles transaction details and local factors, so they remain external/manual.
Worked example
A $30,000 vehicle with a $5,000 qualifying trade-in uses a $25,000 base before state and applicable local tax rates.
