Other Helpful Information

IFTA is an agreement among jurisdictions (states of the United States and Canadian provinces) to simplify the reporting of fuel use taxes by interstate carriers. Most IFTA‑licensed motor carriers find that IFTA significantly reduces the paperwork and compliance burdens for reporting fuel tax liability for gasoline, diesel, propane, blended fuels (gasohol or ethanol), compressed natural gas, E-85, M-85, and A-55.
