In their new  press release, the IRS reminded  taxpayers looking to buy a car before the year is over that they still  have time to take advantage of a 2009 tax break that may not be extended  next year.
Taxpayers who buy a qualifying new motor  vehicle this year after Feb. 16 can deduct the state or local sales  or excise taxes they paid on the first $49,500 of the purchase price.  Qualifying motor vehicles include new passenger automobiles, light trucks,  motorcycles, and motor homes.
Individuals who itemize and those who  take the standard deduction can benefit from this tax break. In states  without a sales tax, other taxes or fees can qualify if they are assessed  on the purchase of the vehicle and are based on the vehicle’s sales  price or as a per unit fee.
The deduction is reduced for joint filers  with modified adjusted gross incomes (MAGI) between $250,000 and $260,000  and other taxpayers with MAGI between $125,000 and $135,000. Taxpayers  with higher incomes do not qualify.
Taxpayers who take the standard deduction  need to complete Schedule L and attach it to Form 1040 or Form 1040A  to increase the standard deduction by the allowable amount of state  or local sales or excise taxes paid on the purchase of the new vehicle.  Also, check the box on line 40b on Form 1040 or line 24b on Form 1040A.  Individuals who itemize should include the allowable amount of state  or local sales or excise taxes from the purchase of the vehicle on Form  1040, Schedule A.
