Hybrid cars incentives?
Depends on which hybrid you purchase (there's nearly 2 dozen hybrid models available in the US right now, so only some have either the fuel economy or clean emissions to qualify), and where you live...
The hybrid tax credit in the US was signed into law with the Energy Policy Act of 2005. The hybrid or alternative fueled vehicle has to have been purchased (or financed) new, and not used or previously owned. They cannot be leased (the leasing company is the owner so they get the credit, not you). Also, they have to be predominantly used in the US.
How much of a US Federal Income tax credit you'll get will depend on what model of hybrid you purchased, and the date of the purchase.
Unfortunately, there was a sunset provision written in for the tax credit, which phases out the credit for a manufacturer over the calendar quarters once a manufacturer has sold more than 60,000 hybrids since Jan. 1, 2006. Both Toyota and Honda have reached this milestone, and therefore the credit has expired for both manufacturers.
There is a letter-writing campaign sponsored by the Union of Concerned Scientists to remove the sunset/phaseout provision on the hybrid vehicle tax credit: https://secure3.convio.net/ucs/site/Advocacy?cmd=display&page=UserAction&id=600
Many states offer tax perks as well - if not a state income tax credit, an income tax deduction, or even reduced sales tax.
Some states, after getting the proper license plate or stickers for the car, allow single occupant use of the HOV (high occupancy vehicle) lanes on the highways.
With the proper EZ-Pass tag (or similar system), some states offer hybrids reduced tolls.
Some localities also offer free parking to hybrids.
So be sure to check in and see what is available in your state:
If you are looking for auto insurance, Farmers and Travelers offer a discount to hybrid owners.
Some companies also have hybrid car incentive plans for their employees (will reimburse you up to a few thousand dollars).
If you are looking for an auto club, Better World Club offers a discounted membership to hybrid owners.
