If you want to get a special incentive for driving a hybrid, you're a few years too late; but a tax credit applies to nearly every electric car and plug-in hybrid on the market and it can, in some cases, effectively reduce your cost for such a model to that of an ordinary gasoline vehicle (or even less).

The widely mentioned $7,500 tax credit is arguably confusing from the start. The federal government gives information on it from a 'Tax Incentives Resource Center,' but it isn't treated as an incentive or rebate to consumers, so you don't get it at the time of purchase. It's not a tax deduction (a reduction in taxable income) either. With a tax credit, you reduce the amount of income tax you owe.

You claim it by making IRS Form 8936 part of your tax return. And while the form is simple and straightforward, there are a lot of other pieces of information you should be privy to.

Use it or lose it. Perhaps the biggest asterisk is that you have a tax liability for that year that meets or exceeds $7,500. If you owe less than that amount for the tax year, you lose the rest of the credit (no, it isn't an additional 'refund,' and any left over can't be applied to your personal taxes the following year).

Not all electric vehicles and plug-ins qualify. To be included on the federal list of vehicles that qualify, the vehicle must be made by a manufacturer (it can't be a conversion); it must comply with the legal definition of a motor vehicle as per the Clean Air Act, title II; and it must have a gross vehicle weight rating (GVWR) of 14,000 pounds or less.

You must buy it new, for your own use. Other requirements are that the new vehicle have its 'original use' with the taxpayer who's claiming the credit. It can't be for resale, and if it is sold, it's a used car. Furthermore, it needs to be a vehicle that's used mostly in the U.S.; and you have to claim the credit for the tax year that the vehicle is placed in service.

If you lease, you probably can't claim it. In what's perhaps the most common misconception for those just starting out cross-shopping EVs. Almost always—but not in every instance—the amount of the credit is claimed by the leasing company (who legally 'owns' the new vehicle), allowing a more attractive lease payment.

Check all of this with your tax preparer before buying. Keep in mind that different rules apply for business use, and to business owners looking to take advantage of this credit. If your purchase is at all dependent on the credit, talk to your tax preparer first. Or better yet, have an accountant who's familiar with this run your numbers and ask you any important questions. And yes, additional local and state credits or incentives might apply; your tax preparer or accountant should be able to advise on which ones apply to your situation.

To qualify, technology-wise, a vehicle must have a battery pack with a capacity of at least 4 kilowatt hours (kWh) and be capable of being recharged from external sources (not just by braking/deceleration or the engine, as in a hybrid). Provided it meets all the other qualifications, the federal government allows a credit of $2,500, plus $417 for a vehicle that has a battery with at least 5 kWh of capacity, and then an additional $417 for each additional kWh up to $7,500.

There's one other interesting detail: The Plug-In Tax Credit isn't a limited-time offer, but it does phase out. Each vehicle manufacturer can sell up to 200,000 vehicles, and after that, the credit amount is phased out over a structured 12-month period. Even for the best-selling electric car, the Nissan Leaf—even with Nissan's plans to introduce more all-electric models—it'll be a few years before that happens.
