I hope this is on topic. I didn't want to start a new thread, but wanted to remind everyone about the AMT limitation. I realize that there has been some discussion of this along with discussion of the $7500 vehicle credit, which is handled differently.
It appears to me that the Federal 50% EVSE tax credit is eliminated completely if you owe even $1 of Alternative Minimum Tax.
From my amateur reading of IRS form 8911 on Nissan's site:
http://www.nissanusa.com/ev/media/pdf/i ... ive-56.pdf line 22 reads that if you subtract the Tentative Minimum Tax from the Regular Tax and the result is zero or less, "stop here, do not file this form" unless you are filing as a business.
To me, that means "sorry, you don't get ANY of this credit if your tentative minimum tax equals or exceeds your regular tax".
I paid about $1,000 of AMT in 2009 and I'll probably pay some in 2010, so I'm assuming that I'm s**t out of luck for this credit. That's important for me to know as I evaluate the AV quote for the EVSE install that I expect in a few days. I ran into a similar limitation for the 2007 tax year, when I installed solar PV and bought a Prius. I didn't pay AMT in that year, but my $2,000 federal solar PV credit eliminated my ability to take the $750 hybrid car credit because of the affect of subtracting the $2,000 credit and how that affected the tentative minimum tax calculation.
AMT often affects certain taxpayers in high tax states like California, where you are pushed into the AMT by deducting the high state income taxes. So yes, we in CA are in the early roll out markets, but there are drawbacks.
