Connecticut IFTA


The International Fuel Tax Agreement (IFTA) is an agreement among jurisdictions (states of the United States and Canadian provinces) to simplify the reporting of the fuel use taxes by interstate carriers. IFTA may significantly reduce 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 A55.
