Louisiana

The IFTA diesel fuel tax rate in Louisiana is 20.0¢ per gallon, which is 20.0¢ lower than your home state (New York: 40.0¢/gal). Low excise rate; below average. This rate is reported on your quarterly IFTA return and net taxes owed or credited are calculated based on miles driven vs. fuel purchased in each jurisdiction.
