A Brief Overview of the U.S. Home Energy Tax Credit

Discover the financial advantages of the U.S. federal solar tax credit for homeowners considering installing a solar system in their main residence. This incentive provides a 30% discount on the current cost of a solar system. If you've set up a system in 2022, it's advisable to speak with your tax consultant to see if you're eligible for a higher credit rate.

Understanding the U.S. Federal Solar Tax Credit:

This tax credit is tailored for homeowners and applies to solar systems installed in primary homes. The credit covers a percentage of qualifying expenses, and thanks to the recent Inflation Reduction Act, the scope of the Investment Tax Credit (ITC) has broadened. Solar systems installed from 2022 to 2032 are eligible for a 30% tax credit, which will drop to 26% in 2033 and 22% in 2034. There's no cap on the amount you can claim.

What Expenses Are Eligible:

Qualifying expenses include solar photovoltaic panels, attic fan power systems (except for the fan itself), labor costs for installation and setup, balance-of-system components, and applicable sales taxes. Standalone batteries with a capacity of 3 kWh or more may also be eligible! For instance, if the solar system you initially purchase includes a single battery with a capacity of less than 3 kWh, but you also buy extra batteries during the installation process that bring the total capacity to more than 3 kWh, then the entire setup may be eligible for the tax credit.

How to Determine Your Eligibility:

To confirm your eligibility for this federal solar credit, review the guidelines set forth by the U.S. Department of Energy and consult your tax advisor.

Steps to Claim the U.S. Federal Solar Tax Credit:

  1. Verify Eligibility: Speak with your tax advisor to confirm your eligibility and to understand how to make the most of the credit.

  2. Fill Out IRS Form 5695: This form, available online, is specifically for claiming renewable energy credits. Guidelines for completing the form are provided.

  3. Apply Credits on Your 1040: Use the total credit amount from Form 5695 to lessen your tax liability on your Form 1040.
