25(C) Tax Credit for Energy Efficient Home Improvements:

The 25(C) Tax Credit, also known as the Nonbusiness Energy Property Credit, is a federal tax credit that allows homeowners to deduct up to 30% of the cost of certain energy-saving home improvements from their federal taxes.

What is the 25(C) Tax Credit?


The 25(C) Tax Credit, officially referred to as the Nonbusiness Energy Property Credit, is a valuable federal tax incentive designed to encourage homeowners to make energy-efficient improvements to their properties. This credit allows homeowners to claim up to 30% of the cost of qualifying energy-saving improvements directly off their federal taxes, providing a substantial financial benefit. To take advantage of this credit, homeowners must file Form 5695 with their annual tax return. The types of improvements that qualify for this credit include, but are not limited to, the installation of energy-efficient windows, doors, roofing, insulation, and certain high-efficiency heating and cooling systems. This credit not only reduces the immediate tax burden for homeowners but also promotes long-term energy savings and environmental benefits by encouraging the adoption of greener home technologies.


Originally established under the Energy Policy Act of 2005, the 25(C) Tax Credit has undergone several changes over the years, reflecting the evolving landscape of energy policy and sustainability initiatives. The credit has been extended and modified multiple times to keep pace with new technologies and changing environmental priorities. Most recently, its validity was extended through the end of 2021 under the Consolidated Appropriations Act of 2021. This extension allowed homeowners additional time to make qualifying improvements and benefit from the tax credit. The periodic extensions and modifications of this credit highlight the ongoing commitment of the federal government to support energy efficiency in residential properties, contributing to broader goals of reducing energy consumption and minimizing environmental impact.

Why is the 25(C) Tax Credit Important?


There are a few key reasons why the 25(C) Tax Credit is an important program for homeowners:


Saves money - By reducing your tax bill, the 25(C) Credit allows you to recoup some of the costs of making energy efficiency upgrades. This can make these improvements more affordable.

Improves home value - Upgrades like new windows and ENERGY STAR products can greatly improve your home's value. The tax credit allows you to make these improvements while spending less.


Helps the environment - By lowering home energy use, efficiency upgrades enabled by the 25(C) Credit also reduce environmental impact. Less energy use means fewer carbon emissions.
