Most people are well aware of the 7,500 federal tax credit but what most might not know about is that congress extended (at the last minute almost) the tax credit for paying for the installation of a home charging device. (This includes getting a 14-50 plug installed in your house up through the HPWC or some other type of EVSE. You get 30% of the cost of installation back as a credit (works very much like the 7,500 credit, although from what I was reading this one IS subject to AMT affects) and it caps at 1,000$ Basically if your equipment and installation costs exceeded 3,334$ you will get the full credit. If you own a business you get the same credit for the installation of the until at your business, and the cap is 30k. So don't forget to ask/look for the right forms to claim this credit because it was approved within the last couple weeks of 2014 and I wouldn't be surprised if your tax professional doesnt think to ask you about it.
