(a) Federal excise taxes are levied on the sale or use of particular supplies or services. Subtitle D of the Internal Revenue Code of 1954, Miscellaneous Excise Taxes, 26 U.S.C.4041, etseq., and its implementing regulations, 26 CFR parts 40 through 299, cover miscellaneous federal excise tax requirements. Questions arising in this area should be directed to the agency-designated counsel. The most common excise taxes are-

(1) Manufacturers’ excise taxes imposed on certain motor-vehicle articles, tires and inner tubes, gasoline, lubricating oils, coal, fishing equipment, firearms, shells, and cartridges sold by manufacturers, producers, or importers; and

(2) Special-fuels excise taxes imposed at the retail level on diesel fuel and special motor fuels.

(b) Sometimes the law exempts the Federal Government from these taxes. Contracting officers should solicit prices on a tax-exclusive basis when it is known that the Government is exempt from these taxes, and on a tax-inclusive basis when no exemption exists.

(c) Executive agencies shall take maximum advantage of available Federal excise tax exemptions.
