What Is the 30% Federal Tax Credit for Mini Splits?

The federal government offers various tax incentives for upgrading to energy-efficient mini splits. For example, you may be familiar with the 30% Energy Efficient Home Improvement Credit (Section 25C) that covered 30% of the installed cost of qualifying mini split heat pump systems up to a $2,000 annual cap. While the 30% tax credit mini splits credit was originally slated to run through 2032, the credit can now only be claimed retroactively for improvements made through the end of 2025. We’re going to help you make sense of what that means for claiming a mini split tax credit in 2026 in this post. You actually have some more state and local mini split incentives in Indiana that can still cut the cost of upgrading.

Is the Mini Split Tax Credit Still Available in 2026?

It’s not your imagination that there used to be a federal tax credit for mini splits. However, the extended 25C credit that would have applied for any system placed in service after Dec. 31 of 2025 was terminated with the passing of the One Big Beautiful Bill Act in July of 2025. The new cutoff was set at Dec. 31 of 2025. You can still retroactively claim the credit on a 2025 tax return for an installation from before the cutoff date. However, new installations from 2026 do not qualify for the federal tax credit.

What if My System Was Installed Before December 31, 2025?

Your mini split is still claimable on a 2025 tax return if it was installed and operational in 2025. You need to do a little homework to get the credit. This requires gathering all receipts from purchase and installation and obtaining AHRI certification documentation. File IRS Form 5695 with your 1040. If this feels a little complicated, consider hiring a tax professional to explain everything and help you file.

What Savings Are Still Available for Indiana Mini Split Owners in 2026?

While the federal tax credit for mini splits is gone, Indiana residents have meaningful alternatives that can help them improve heating and cooling in their homes. Let’s cover the three main efficiency home improvement credits for mini splits homeowners like you can still take advantage of today.

Indiana Energy Saver Program heat pump and cooling rebates are available through the Home Appliance Rebates (HEAR) and Home Efficiency Rebate (HOMES) programs. Discounts through HEAR are based on the median income (AMI) of the county you live in and the number of people in your household. The maximum discount you can receive is $14,000. You can use the official HEAR calculator on the Indiana Energy Saver Program’s website to estimate how much you could qualify for. Discounts through HOMES for single-family residences can reach up to $4,000 based on how much your improvement reduces your home’s energy consumption.

Utility rebates are also available for homeowners in Indiana who are getting new mini split systems. The Duke Energy Indiana heat pump rebate offers special rebates when you install a high-efficiency heat pump or ductless mini-splits. While rebate amounts change frequently, past offers have ranged from $250 to $3,000 for various systems. Specific rebate amounts can vary based on SEER and HSPF ratings.

The AES Indiana Home Improvement Rebates program can get you up to $725 off your upgrade. In 2026, rebate amounts for mini split systems range from $100 for installing systems with 15.2 SEER ratings and 8.7 HSPF ratings to $725 for systems with 23+ SEER ratings and 10 HSPF ratings.

Lastly, NIPSCO residential rebates are offered when homeowners choose certain high-efficiency heating and cooling equipment. Historically, rebates for systems have ranged from $600 to $1,000.

Does Losing the Tax Credit Change Whether a Mini Split Is Worth It?

There’s no denying that the federal tax credit was a great incentive for upgrading to a new, high-efficiency mini split. While the investment math has shifted with the elimination of the credit, homeowners still have plenty of reasons to upgrade. Saving money is still one of the main reasons, even without a federal-level ductless heat pump tax credit or AC rebate.

Mini splits provide long-term energy efficiency and zoning benefits for your home. They remain the top-tier choice for rooms like additions, master bedrooms, finished attics, and bonus rooms that struggle with cooling because ductwork extensions don’t make sense. For the right situation, getting a mini split is still going to bring you out ahead. It takes assessing installation costs, long-term energy savings, and your household’s needs to truly understand the numbers. Plus, local rebates and discounts can still shave off a meaningful chunk of your upfront cost.
