The Cash for Clunkers program, may have ended. However, the original Stimulus Act for Automobile purchases provided for a sales tax write off . Even if you do not itemize, you may write off sales tax, local tax, and excise tax for new vehicles, in an above the line deduction. This is particularly attractive for those individuals who have state income taxes, since this is ADDITION to the state income tax deduction.
According to Edmunds Daily
In sum, state and local motor vehicle sales taxes and motor vehicle excise taxes are all deductible on any new car, light truck, recreational vehicle, or motorcycles purchased between February 17th and December 31, 2009. Individuals with a modified adjusted gross income of less than $125,000 or joint-filers making less than $250,000 a year in 2009 qualify.
There will also be significant tax credits for plug-in hybrids purchased beginning December 31, 2009 that will extend to the first 200,000 models sold by each automaker. For more details on the stimulus package and green vehicles, see the Green Car Advisor blog entry here.
