Bipartisan Budget Act of 2018 (BBA), signed February 9, 2018, reinstated the nonbusiness 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.
While ENERGY STAR provides some information about federal tax credits for energy efficiency (see: Federal Income Tax Credits), the tax credits are administered by the IRS.

In addition to federal tax credits, local rebates may be available in your area. That information is available through the ENERGY STAR Rebate Finder, where you can enter your zip code to find rebates and other offers available in your area.
