OVERVIEW OF THE FINAL REGULATIONS UNDER SECTIONS 30 AND 179A These regulations explain the tax credit that is sometimes available to those who acquire electric vehicles and the deduction for those who acquire (certain) clean-fuel vehicles or equipment to refuel them. Clean-fuel vehicles are powered by electricity or a low-emission fuel like natural gas. The credit is not available for vehicles that previously used conventional fuels. In some instances taxpayers are required to repay some of the tax benefits they have received if the vehicle involved is taken out of service prematurely. This happens, for instance, if an electric vehicle is converted to run on conventional fuels within three years of when the taxpayer first used it. But the taxpayer is not responsible for recapture if the vehicle is transferred to another owner and, unbeknownst to the seller, becomes ineligible for tax benefits. These regulations became effective on October 14, 1994. Owners whose vehicles ceased to qualify for tax benefits prior to that date may use any reasonable method to compute the amount that must be repaid. An additional explanation and a full text of the regulations appears in the Federal Register of August 3, 1995.
