Geothermal Tax Credit Reinstated
Bipartisan Budget Act of 2018 reinstated the non-business energy property credit for 2017, and the residential energy efficient property credit for qualified small wind energy property costs, qualified geothermal heat pump property costs, and qualified fuel cell property costs to the end of 2021. You may claim these credits on your 2017 tax return if you otherwise meet the criteria. If you have already filed your return, you will need to file an amended return (Form 1040X) to claim these credits.
