So it looks like a Prius owner like myself (fairly new - since October 2012) can't claim any Federal or State tax deductions for a 2012 Prius Hatchback - am I correct in this assumption? Something about they were all phased out prior, with the exception of some all-electric vehicles and some plug-in models?
Yes, it's been gone long ago. Some states even decided to ADD tax to the hybrids Fuel Efficient Vehicle Tax Incentives Information Center
