Here's a tidbit of information that could make a difference of a couple of hundred dollars or more, courtesy of the best solar installers in the Bay Area.* When should you apply your 30% tax credit? Before, or after you subtract your rebate from the full price of your system?
"Rebate First:" subtract the rebate first, then take 30% ITC on the difference.
"ITC First:" take the 30% ITC on the full purchase price, subtract the rebate, and treat the rebate as ordinary income, paying federal and state taxes on it.
Which is better? If my client's marginal tax rate is less than 30%, I'll ask them to consider "Rebate First." If it is greater than 30% they should consider "ITC First."
