Do Mini Splits Qualify for the Federal Tax Credit? 2025 Rules

Yes, mini splits qualify for the federal tax credit, but only if the system was placed in service on or before December 31, 2025 and meets the required efficiency standards. The Energy Efficient Home Improvement Credit under Section 25C pays 30% of total project costs up to $2,000 per year for a qualifying heat pump. For any mini-split installed in 2026 or later, the credit is gone.¹

The Credit Ended After December 31, 2025

The Inflation Reduction Act of 2022 had set this credit to run through 2032. Federal legislation enacted in 2025 cut that short. The statute now reads that Section 25C “shall not apply with respect to any property placed in service after December 31, 2025.”²

A mini-split installed in 2026 does not qualify, no matter how efficient. There is no replacement federal credit for residential heat pump installations. State energy offices and local utility companies still run their own rebate programs, and those exist independently of the federal credit.

If your system was installed during the 2023, 2024, or 2025 tax year and you haven’t yet filed, you can still claim the credit on the return for the year installation was completed.

Efficiency Standards Your System Must Meet

Not every mini-split qualifies. The equipment must meet or exceed the highest efficiency tier (excluding any advanced tier) set by the Consortium for Energy Efficiency (CEE) in effect at the start of the calendar year the system is installed.³ For 2025 installations, that is CEE Tier 1. Split heat pumps must clear three thresholds:

SEER2 of at least 16.0 (seasonal cooling efficiency)
EER2 of at least 9.8 or 11.0, depending on the qualification path (peak cooling efficiency)
HSPF2 of at least 8.0 or 8.5, depending on the qualification path (heating efficiency)

These “2” ratings replaced the older SEER, EER, and HSPF ratings and reflect updated testing methods that account for higher static pressure in real-world installations. When you compare product specs, make sure the numbers on the datasheet are the newer ones. Systems carrying the ENERGY STAR Most Efficient label generally meet the benchmarks, but the CEE tier is the standard the IRS applies, so confirm the specific model qualifies before filing.

How Much the Credit Is Worth

The credit equals 30% of total qualifying costs, including the equipment and the labor for onsite preparation, assembly, and installation.² The annual cap for heat pumps is $2,000. That cap is separate from the $1,200 annual limit that applies to windows, doors, and insulation, so a mini-split installation does not eat into what you can claim for those other improvements in the same year.³

The $2,000 heat pump limit resets each tax year. Someone who installed qualifying equipment in both 2024 and 2025 could have claimed up to $2,000 in each of those years. There is no lifetime cap.²

The credit is nonrefundable. It reduces the federal income tax you owe, but it cannot create a refund on its own. If the credit is larger than your tax liability, the difference is lost. There is no option to carry it forward.³

Who Can Claim the Credit

The credit is available to individual taxpayers who installed a qualifying mini-split in an existing home in the United States. New construction does not qualify. The system has to be added to, or replace equipment in, a home that already exists. Landlords who do not personally live in the property cannot claim the credit.⁴

Heat pumps follow more flexible property rules than some other improvements under Section 25C. Windows, doors, and insulation require installation in a home you both own and use as your principal residence. A mini-split only needs to be installed in a home you use as a residence. You can claim the credit for a system in your second home, and you can claim it even if you rent the home rather than own it.⁴

How Rebates and Subsidies Change the Math

If you received financial help toward the purchase, some of it may reduce the amount you can use to calculate the 30% credit:

Public utility subsidies are always subtracted from qualified expenses, whether the payment went to you or directly to your contractor.
Manufacturer or seller rebates are subtracted when the rebate is tied to the cost of the equipment and comes from someone involved in the sale.
State energy incentives are generally not subtracted, unless they qualify as a rebate or purchase-price adjustment under federal tax law.

You can still stack the federal credit with state programs and utility rebates. You just need to reduce your qualified costs by any amount that counts as a purchase-price adjustment before you multiply by 30%.³

How to Claim the Credit on Your Return

You claim the credit on IRS Form 5695, attached to your Form 1040. Heat pump costs go in Part II, on Lines 29a and 29b, where you enter the cost and the manufacturer’s identification number for each qualifying system.⁵

The QMID Requirement

For systems installed in 2025, you must include a Qualified Manufacturer Identification Number (QMID) for each item claimed. The QMID is a four-character alphanumeric code assigned by the manufacturer and appears on the manufacturer’s certification for the product. Without a valid QMID, the IRS may deny the credit, so confirm you have the number before filing.⁵

Documents to Gather

An itemized receipt showing equipment cost separate from labor.
The manufacturer’s certification confirming the system meets the required efficiency standards. It lists the model number, serial number, and QMID. Keep it with your records; you do not attach it to the return.⁵
The installation contract, which documents that the system was placed in service on or before December 31, 2025.

Tax software will walk you through the energy credits section. Paper filers attach the completed Form 5695 to Form 1040.⁶ Hold on to the receipts, certification, and installation records for at least three years after filing, which matches the general statute of limitations for IRS audits.
