The Energy Tax Act of 1978 established a Gas Guzzler Tax on the sale of new model year vehicles whose fuel economy fails to meet certain statutory levels. The gas guzzler tax applies only to cars (not trucks) and is collected by the IRS.
The fuel economy figures used to determine the Gas Guzzler Tax are different from the fuel economy values provided on this web site and in the Fuel Economy Guide. The tax does not depend on your actual on-the-road mpg, which may be more or less than the EPA published value. The purpose of the Gas Guzzler Tax is to discourage the production and purchase of fuel inefficient vehicles. The amount of any applicable Gas Guzzler Tax paid by the manufacturer will be disclosed on the automobile's fuel economy label (the window sticker on new cars).
