In an effort to promote clean energy adoption, several U.S. states offer residents tax credits for going solar. These are in addition to the Residential Clean Energy Credit, a federal income tax credit worth up to 30% of the total cost of an eligible system.
This article will provide general information on which states offer a state income tax credit, along with links to required forms and any corresponding instructions. Palmetto customers who installed their system in a state offering such credits will have already been sent detailed instructions along with their contract.
In each state described in this article, the incentive is a tax credit, not a rebate or refund. You must have state income tax liability to be eligible; however, many allow you to utilize the credit in future years if you do not have sufficient tax liability the same year the system was installed.

New Mexico offers eligible solar owners a state income tax credit, the New Solar Market Development Income Tax Credit (SMDTC), worth 10% of the total system cost up to a maximum of $6,000 per project. To secure the credit, a complete application before the annual $12 million budget is fully allocated. Once the program budget has been fully allocated for that tax year, no new credits will be granted. The program budget status is publicly tracked on this dashboard.
In order to qualify for the tax credit, you must apply for and obtain a Certificate of Eligibility through the New Mexico Energy, Minerals, and Natural Resources Department (EMNRD). While Palmetto does not have all the information required to file this application on customers’ behalf, we will ensure projects meet all the technical program requirements and issue a partially completed application to the customer of record once the system has been granted Permission To Operate (PTO). Customers must then complete and submit an application with all the required information online to the New Mexico Energy Conservation and Management Division (ECMD).
The application, instructions, and submission portal can be found on the New Mexico EMNRD’s website below.
Once you submit your application, the New Mexico ECMD will review the application. If approved, you will receive a Certificate of Eligibility via email that you must submit with your state income taxes for the tax year in which your system was turned on. You must obtain a Certificate of Eligibility to qualify for the tax credit.
South Carolina offers eligible solar owners a state income tax credit worth 25% of the total cost of their solar energy system up to a maximum of $35,000 over 10 years. The maximum credit amount that a homeowner can receive each year is less than $3,500 or 50% of their annual state tax liability. If homeowners cannot claim their full tax credit in the first year, they will have up to 10 years to do so. The required form, SCH.

Utah offers eligible solar owners a state income tax credit worth up to 35% of the total system cost up to a maximum of $800 for installations in 2022 or $400 for installations in 2023. Customers must file form TC-40A with their state income tax return and TC-40E with the Governer’s Office of Energy Development.
On form TC-40A, under “Part 4 - Nonapportionable Nonrefundable Credit,” you’ll want to write “21” under the “Code” column for renewable residential energy systems credit. Under the “Amount” column, you’ll want to write “$800” if your system was installed in 2022 or “$400” if installed in 2023. You can complete the rest of the form as you normally would when filing your state taxes. This form should be filed with your state income tax return.
TC-40A can be found on the Utah State Tax Commission’s website below:
TC-40E can be completed online through the Utah Office of Energy Development’s tax credit portal.
The Utah Office of Energy Development requires a non-refundable application fee of $15 that must be paid by credit card to receive the TC-40E tax form. Paying the fee does not guarantee that you will be approved for the tax credit.
TC-40E should be filed with the Governor’s Office of Energy Development, not with your state income tax return. To register, follow the instructions provided on their website. If no instructions are provided, you may use these tips as guidelines to help submit your application:
