I installed energy efficient windows but my invoice is for the project, including labor. Without the cost of each window, am I ineligible to take the tax credit?

No, you are not necessarily ineligible.  The best course of action would be to reach out to your contractor and request an itemized invoice.

If it is not possible to obtain this, you could use a good faith estimate of the breakout between the labor and windows.  Keep in mind, if you are audited this will be more difficult to prove, so ensure you are reasonable in your allocations. I would suggest researching the cost of the same model of window you had installed, if possible, and keeping it with your tax records.

Thank you for your input.   I’m unable to reach out to Pella for pricing since I don’t even have a detailed measurement  for any of the windows in my contract.   Based on other information I’ve gathered, I’m going to assume a  generous 100% markup for profit plus installation.  I’ll break the 14  windows down by size with my own measurements, and try to get good faith estimate in place for each window. Even if I don’t get much of a tax break, It’s better than nothing, and I have proof the project was done.    
Thanks so much for the recommendation.
