The IFTA diesel fuel tax rate in Maine is 31.2¢ per gallon, which is 15.2¢ higher than your home state (Hawaii: 16.0¢/gal). Includes excise tax. 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.

Maine participates in IRP; registration through Maine BMV. No separate state operating permit; UCR registration required. Your IRP registration covers operating in Maine as long as it is listed on your cab card.
