Switching to energy-efficient windows can save you money on energy bills and make your home more comfortable. If you live in South Carolina, you have access to financial incentives like federal tax credits, utility rebates, and upcoming state programs. Here’s a quick breakdown:
- Federal Tax Credit (25C): Covers 30% of eligible window costs, up to $600 annually, through 2032. Requires ENERGY STAR-certified windows.
- Utility Rebates: Providers like Duke Energy offer rebates up to $275 for qualifying upgrades. Check your local utility for details.
- State Programs (Launching 2026): HOMES and HEAR rebates could save $2,000–$16,000 depending on energy reductions and income.
Steps to Claim Rebates:
- Choose ENERGY STAR-certified products that meet program standards.
- Use licensed contractors for installation (required by most programs).
- Keep all receipts, labels, and documentation for tax filings or rebate applications.
- Submit IRS Form 5695 for federal tax credits or utility-specific forms for rebates.
Combining federal credits with state or utility rebates (for separate projects) can maximize your savings. Plan ahead, as some programs require pre-approval. Upgrading your windows not only reduces energy costs but also improves your home’s efficiency over time.
Energy Rebates and Tax Credits Available
If you’re a South Carolina homeowner planning energy-efficient window upgrades, you’re in luck. There are financial incentives available to help offset the costs, including federal tax credits and rebates from local utility companies. Each program has its own set of rules and benefits, so it’s worth exploring your options.
Federal Tax Credit (25C)
The federal government offers tax credits for certain energy-efficient home improvements, including window upgrades. The details – like the percentage of the credit and the maximum amount you can claim – change periodically. To get the most accurate and up-to-date information, check the IRS guidelines or consult with a tax professional.
Local Utility Rebates
Many utility providers in South Carolina have rebate programs to encourage energy-efficient upgrades. For example:
- Duke Energy Carolinas: Offers rebates of up to $275 for ENERGY STAR®-certified window upgrades.
- Santee Cooper and Dominion Energy SC: Provide rebates based on results from comprehensive energy assessments.
To take advantage of these rebates, visit your utility provider’s website or check out the DSIRE Database by entering your ZIP code. Make sure to review the application process and eligibility requirements before starting your project.
Additionally, the South Carolina Energy Office is rolling out new state-level programs funded by the Inflation Reduction Act. Programs like HOMES and HEAR include rebates for window upgrades, with potential savings ranging from $2,000 to $16,000 for broader home energy improvements.
Credit Limits and Deadlines
One important thing to keep in mind: federal tax credits and utility rebates usually can’t be combined for the same individual upgrade. However, you can use different incentives for separate qualifying projects. Carefully review the guidelines for each program to ensure your upgrades meet the requirements.
Eligibility Requirements for Rebates and Credits
Knowing the criteria for energy rebates and tax credits can help you plan your window upgrade project more effectively. Each program comes with its own set of rules that determine whether your investment qualifies for financial incentives.
Product Efficiency Standards
To qualify for rebates and tax credits, your new windows must meet specific energy performance standards, which vary depending on the program.
For the federal Energy Efficient Home Improvement Tax Credit (Section 25C), your windows need to meet the ENERGY STAR Most Efficient criteria. To confirm eligibility, you can use the ENERGY STAR Climate Zone Finder and the NFRC Certified Product Directory – look for a green-shaded field as an indicator.
Duke Energy Carolinas has its own requirements: windows must have a Solar Heat Gain Coefficient (SHGC) of 0.21 or lower and a U-Factor of 0.27 or lower. These standards apply specifically to windows facing east, west, or south.
For South Carolina, the upcoming Home Energy Rebate programs (HOMES and HEAR), set to launch in 2026, will include energy-efficient windows as eligible upgrades. However, the exact standards for these programs are still being finalized.
Meeting these efficiency standards is just the first step, with additional requirements for installation and documentation to follow.
Installation and Home Type Requirements
Most rebate programs require professional installation, though the specifics depend on the program.
For Duke Energy’s rebate program, you must hire a licensed and insured contractor. Similarly, South Carolina’s HOMES program will require you to use a program-approved contractor once it launches.
Federal tax credits, on the other hand, only cover the cost of the windows, though professional installation is recommended.
Eligibility can also depend on your home type. South Carolina’s HOMES program will be available for both single-family and multifamily homes. Renters may qualify for the HOMES and HEAR programs as well, but written permission from the property owner will be required.
Documentation and Compliance
Once you’ve met the product and installation standards, keeping proper documentation is crucial.
“While documentation is not required to be filed with your tax return, it may be required if your tax return is audited. The IRS strongly recommends you retain your purchase receipts and installation records as well as any Energy Star and/or National Fenestration Rating Council labels affixed to the windows, skylights, and doors.”
To claim the federal tax credit, you’ll need to file IRS Form 5695 with your tax return for the year the windows were installed. Keep all purchase receipts, contractor invoices, and installation records, along with the ENERGY STAR and NFRC labels attached to your windows.
Manufacturers often provide certification statements to assist with your IRS filing, so be sure to request these documents when purchasing your windows. For utility rebates, like Duke Energy’s program, you’ll need to complete their specific rebate form and provide proof that a licensed and insured contractor handled the installation.
When South Carolina’s HEAR program launches, it will offer a DIY option for specific projects like electric kitchen appliances, but this option will not apply to window upgrades. For DIY projects, you’ll need to submit proof of purchase and project photos for reimbursement.
Keeping all receipts, invoices, and certification labels organized will simplify the application process and help you avoid any delays.
Step-by-Step Guide to Claiming Energy Rebates
Step 1: File Your Federal Tax Credit Forms
Start by completing the necessary federal tax credit paperwork. Specifically, you’ll need to file IRS Form 5695 along with your tax return for the year the installation was completed. Make sure to keep all your purchase and installation receipts as proof. These records might come in handy if you need to verify your claim later.

How to Maximize Savings with Energy-Efficient Windows
Combining Incentives for Greater Savings
Want to stretch your dollar further on window upgrades? Pairing incentives is the way to go. Combine the federal tax credit with local or municipal rebates to cut down on upfront costs. Start by claiming the federal tax credit, then research what rebates your local government or utility companies offer. Once you’ve completed the installation, make sure to submit all necessary paperwork promptly and keep thorough records of your expenses to ensure you receive every penny you’re entitled to.
Long-Term Energy Cost Reductions
Energy-efficient windows aren’t just a one-time savings opportunity – they’re an investment that keeps paying off. Did you know that windows are responsible for 25% to 30% of a home’s heating and cooling energy loss? Switching to ENERGY STAR-certified windows can make a noticeable difference. For example, upgrading from single-pane windows could save you anywhere from $101 to $583 annually. Even replacing older double-pane windows can trim $27 to $197 off your yearly energy bills. Over the course of 10 years, these savings could add up to $710 to $5,000, helping many homeowners recoup their initial investment in just 8 to 10 years. Plus, energy-efficient windows can slash your overall energy bills by up to 13% and reduce home energy use by 7% to 15%. On top of that, by lightening the load on your HVAC system, you could also save on maintenance costs in the long run.
New Incentive Programs in South Carolina
If you live in South Carolina, there’s even more good news. The state frequently updates its energy efficiency programs to help homeowners cut energy use and save money. Check with state agencies and local utility companies for the latest rebates and tax credit opportunities, as these programs and their funding can change. Many of these incentives encourage a comprehensive approach to energy efficiency, so you might be able to combine window upgrades with other improvements like insulation or HVAC system updates. Icon Window & Door keeps tabs on all current South Carolina incentive programs and can help you figure out which ones apply to your project. To get the most savings, apply as early as possible and stay on top of local updates.

Key Takeaways for Homeowners
If you’re planning to claim energy rebates, having a solid strategy is crucial. Federal tax credits can cover up to 30% of eligible window costs, with a maximum benefit of $600 through December 31, 2032. Opt for ENERGY STAR-certified windows and keep all related records handy.
To maximize savings, plan your upgrades carefully to stay within the $3,200 annual credit limit. Spread out your projects over multiple years to take full advantage of these credits.
Documentation is key. Hold onto receipts, certification statements, and installation records, and file IRS Form 5695 with your tax return. For utility rebates, like those offered by Duke Energy Carolinas, you’ll need proof of installation by a licensed contractor and a home energy assessment completed within 24 months. Following these steps will help you streamline the rebate process and connect with experienced local suppliers.
Looking ahead, the HOMES and HEAR programs, launching in 2026, could provide rebates ranging from $2,000 to $16,000, depending on energy savings and income levels. These state rebates can be combined with federal tax credits, but not for the same specific upgrade. Incorporating these future opportunities into your plans can help you maximize both short-term rebates and long-term energy savings.

Beyond the immediate financial benefits, energy-efficient windows can lower utility bills and boost your home’s value over time. Combining federal credits, state rebates, and reduced energy costs makes window upgrades one of the smartest home improvements you can undertake in South Carolina.
To get started, schedule a home energy assessment and research eligible products. Being prepared will ensure you’re ready to act when South Carolina’s new rebate programs roll out, helping you secure maximum savings.
FAQs
How do I know if my windows qualify for energy rebates or the federal tax credit?
To determine if your windows qualify for energy rebates or the federal tax credit, they must meet the ENERGY STAR Most Efficient certification standards. Additionally, your home needs to be your primary residence in the U.S., and the windows should adhere to specific energy efficiency guidelines.
First, ensure that your windows are ENERGY STAR certified and meet the Most Efficient criteria. After confirming this, you can claim the federal tax credit by filling out IRS Form 5695. For utility rebates, contact your local energy provider to check eligibility and learn about the application process.
What documents do I need to claim energy rebates for window upgrades in South Carolina?
To claim energy rebates for window upgrades in South Carolina, you’ll need to gather a few key documents:
- Proof of purchase: This includes receipts or invoices that clearly show the purchase date and cost of the windows.
- Energy efficiency certification: Documents like an Energy Star certification to confirm the windows meet the rebate eligibility criteria.
- Manufacturer certification statement: This verifies that the product qualifies for energy rebates or federal tax credits.
For federal tax credits, don’t forget to file IRS Form 5695 with your tax return. Be sure to keep all receipts and certification documents on hand for verification purposes. Having everything organized will make the rebate or tax credit process much easier.
Can I use both federal tax credits and South Carolina’s HOMES or HEAR rebates for the same window upgrade?
No, you can’t combine federal tax credits with South Carolina’s HOMES or HEAR rebates for the same window upgrade project. These federal and state incentives can’t be stacked for a single energy-efficient improvement. However, you can still use them separately for different projects. This way, you can make the most of both programs to increase your total savings on energy-efficient upgrades.
