Fuel Economy

Gas Guzzler Tax

Congress established Gas Guzzler Tax provisions in the Energy Tax Act of 1978 to discourage the production and purchase of fuel-inefficient vehicles. The Gas Guzzler Tax is assessed on new cars that do not meet required fuel economy levels. These taxes apply only to passenger cars. Trucks, minivans, and sport utility vehicles (SUV) are not covered because these vehicle types were not widely available in 1978 and were rarely used for non-commercial purposes. The IRS is responsible for administering the gas guzzler program and collecting the taxes from car manufacturers or importers. The amount of tax is posted on the window stickers of new cars - the lower the fuel economy, the higher the tax.
