Most of the energy credits existing under current federal law expire at the end of 2016. Solar energy credits have been extended but a variety of credits for energy efficient windows, doors, A/C systems etc expire on December 31st. For anyone still wishing to take advantage of these credits, the items need to be installed and in use by December 31st. As a caveat, these credits have expired before and then been reinstated by congress. Will these credits be extended by the lame duck congress or reinstated in the future? Well, my crystal ball isn’t working this morning so we will have to stay tuned to see what happens.
