Since 1978, the excise tax for 10% gasohol fuels has included a partial exemption from the federal excise tax rate for gasoline. Extended and revised over the years, the current federal excise tax rate for 10% gasohol is 13.2 cents per gallon. This is a 5.2 cents per gallon exemption from the 18.4 cents per gallon tax rate for gasoline. The 5.2 cents per gallon amount will continue through December 31, 2004. The amount will drop to 5.1 cents per gallon for the period of 2005 - 2007. These schedule amounts were included in the Transportation Efficiency Act of the 21st Century (TEA 21), enacted in June 1998. TEA 21 expires on December 31, 2007.

In addition to 10% gasohol, lower excise tax rates are provided for two other gas/alcohol mixtures. 7.7% gasohol has an excise tax rate of 14.4 cents per gallon and 5.7% gasohol has an excise tax rate of 15.4 cents per gallon. Taxes are filed quarterly.

Publication 510, Excise Taxes for 2003, describes the three types of gasohol. The excise tax rates themselves are included in the Instructions for Form 720.
