I have been considering getting a solar system added to the house. I am 64 collecting SS. I did not have a tax bill last year to pay. My thought is in order to get the 26% tax credit I could do a Roth conversion so that I had tax liability. First of all does this sound like a good idea? Second I would need guidance in just how much to convert to put me in the right range of tax liability. Thanks for any help. Hopefully enough info to get started.
