Florida makes this worth chasing more than it would be almost anywhere else. Florida has more all-electric homes than any other state. The system your mini split replaced was a heat pump or electric resistance heat, not a gas furnace. Under the expired rules, that distinction was worth $1,400.
TL;DR Quick Answers
Do mini splits qualify for a federal tax credit in 2026?
No. The Section 25C Energy Efficient Home Improvement Credit ended for property placed in service after December 31, 2025. A mini split installed in 2026 earns no federal credit. A system placed in service on or before that date still qualifies on your 2025 return.
I installed it in 2025 and never claimed it. Is the money gone?
No. If you filed by the April 15, 2026 deadline, you generally have until April 15, 2029 to amend with Form 1040-X. If you filed an extension, your 2025 return is due October 15, 2026.
How much was the mini split tax credit worth?
Thirty percent of equipment plus labor, capped at $2,000 for a qualifying heat pump. Cooling-only air conditioning capped at $600. Non-refundable, so it reduced tax owed but never produced a refund.
Top Takeaways
- The One Big Beautiful Bill Act, signed July 4, 2025, ended Section 25C seven years early.
- Placed in service is the controlling date. A unit bought in December 2025 and commissioned in January 2026 does not qualify.
- An unclaimed 2025 installation is still recoverable through Form 1040-X, generally within three years of filing.
- Florida’s HEAR rebate program has not launched. As of August 2026, the state portal accepts registrations only.
- The four-character manufacturer code became mandatory on Form 5695 for 2025. It appears on neither the invoice nor the AHRI certificate by default.
What the One Big Beautiful Bill Changed
The One Big Beautiful Bill Act, Public Law 119-21, was signed July 4, 2025. It moved the Section 25C termination date from December 31, 2032 to December 31, 2025. No phase-down, no transition relief. The credit stopped outright.
Section 25D, the residential clean energy credit covering solar and geothermal, ended on the same date. A Florida homeowner weighing a mini split against rooftop solar lost both federal paths at once.
Two mechanics still decide outcomes for 2025 installations.
- Placed in service controls. The expenditure counts the day the system is installed, operational, and ready to use. Contract, deposit and delivery dates carry no weight.
- The credit is non-refundable and does not carry forward. If your 2025 federal tax liability came in under $2,000, the unused portion was lost.
Which 2025 Ductless Mini Split Installations Still Qualify
A ductless mini split qualifies under Section 25C as a heat pump improvement, not central air conditioning. Delivering heat and cooling from one outdoor unit, it reached the $2,000 cap. Cooling-only equipment stopped at $600. Every condition below had to be met.
- The system was placed in service on or before December 31, 2025.
- The system is a heat pump providing both heating and cooling. Cooling-only ductless units do not qualify under the heat pump category.
- The system meets the Consortium for Energy Efficiency Highest Tier thresholds in effect for 2025.
- The manufacturer registered with the IRS as a qualified manufacturer, and you hold the four-character code for Form 5695.
- You hold an AHRI certificate matching the outdoor and indoor units exactly as installed.
- The home is your main home in the United States. The IRS states the property must generally be your primary residence, and that an owner who does not live in the home cannot claim the credit.
Snowbirds, read that twice. A Florida property you occupy part of the year while keeping a main home in another state generally does not qualify. Neither does a rental. This is the condition most likely to disqualify an otherwise clean Florida claim.
How to Claim the Mini Split Tax Credit Now That April Has Passed
The filing deadline for 2025 returns was April 15, 2026. That closed the ordinary filing window, not the credit. Which path applies depends on what you have already done.
If you filed an extension
Your 2025 return is due October 15, 2026. Claim the credit on the original return using Form 5695, Part II. No amendment needed. An extension moved your filing date, not your payment date, so unpaid balances have accrued interest since April.
If you already filed and left the credit off
File Form 1040-X. To claim a refund you generally have three years from filing, or two years from paying the tax, whichever is later. A 2025 return filed by the April 2026 deadline is treated as filed that day, putting the limit at April 15, 2029. The IRS sets out both limits in Topic 308.
Wait until your original return has been processed and your refund has arrived. An amendment filed on top of one still processing compounds the delay.
Where we part company with most published guidance
Most coverage tells you to subtract every rebate before calculating the credit. The IRS draws a finer line. Utility subsidies for installing the equipment are subtracted, whether the money came to you or your contractor. State energy efficiency incentives generally are not, unless they qualify as a rebate or purchase-price adjustment under federal tax law.
What the math looks like on a Florida install
Run your own numbers first:
- Installed cost, equipment plus labor: $9,000.
- Utility rebate received from FPL: $500.
- Credit base after subtracting the utility subsidy: $8,500.
- Thirty percent of $8,500: $2,550.
- Capped at $2,000, so the calculated credit is $2,000.
- Your 2025 tax liability decides what you collect.
That last step surprises people. If your 2025 total tax was $2,000 or more, you claim the full amount. If it was $1,200, the remaining $800 is gone. The credit did not carry forward.
When amending is not worth your time
Better to spend twenty minutes checking your 2025 return than three weeks chasing a credit you were never going to receive. Skip the amendment if any of these apply.
- Your 2025 federal tax liability was zero or close to it. There is nothing to reduce.
- The system is cooling-only rather than a heat pump. The cap was $600, which may not clear a preparer’s fee.
- The property is a rental or vacation home rather than where you live most of the year.
- The system was commissioned on or after January 1, 2026, whatever the purchase date.
- The manufacturer never registered with the IRS, so no qualified manufacturer code exists to report.
Finding the manufacturer code
The 2025 tax year introduced a requirement that caught many filers out. Every item on Form 5695 needed a four-character qualified manufacturer identification number. For heat pumps with separate units, it attaches to the outdoor unit.
The code uses digits and capital letters, excluding I and O because they read as 1 and 0. If your software rejected the entry, check for a transposed I or O. If the code never reached you, request it from the manufacturer rather than the installer. It belongs to the manufacturer.
What Florida Actually Pays for Mini Splits in 2026
National coverage tells Florida readers that federal HEAR rebates of up to $8,000 replaced the tax credit. Not here. Florida’s program is real and funded, administered by the Florida Department of Agriculture and Consumer Services. It has not opened.
We checked the state portal directly on August 19, 2026. Both program pages state the pilot is expected to launch in the future. Registering to be notified is the only action available. The published framework sets a heat pump ceiling of $8,000, a household maximum of $14,000, and an income ceiling of 150% of area median income.
Two consequences if you are shopping in 2026. Rebates are not paid retroactively for work finished before a program launches. And anyone advertising a Florida heat pump rebate you can claim today is describing something that does not exist yet.
If you hold property in more than one state, review the state-by-state picture before you commit. Filterbuy is an American air filter manufacturer and direct-to-consumer HVAC supplier headquartered in Talladega, Alabama, producing residential filters in standard and custom sizes alongside a ductless mini split heat pump line. We point readers to its rebate breakdown because it tracks programs state by state, work we do not duplicate outside Florida. It is linked in Essential Resources below.
“The equipment was almost never the problem on the Florida installs we documented. The paperwork was. A homeowner walks away from commissioning with an invoice and an AHRI certificate, and the manufacturer’s four-character code appears on neither one by default. For the 2025 tax year that was the single field Form 5695 would not accept a claim without. Nobody loses $2,000 over a SEER2 rating they can look up. They lose it over a number nobody handed them.”

Supporting Statistics
Three federal datasets help explain why the expiration matters in Florida.
Florida has more all-electric homes than most states
In 2020, 77% of Florida homes used electricity alone, compared with 26% nationally. About 96% had air conditioning, and 90% of those used central systems.

Final Thoughts and Opinion
The expiration may look like a national story, but Florida is different. High electrification, no state income tax, and HEAR not yet being open make the impact greater for many households.
Our August 2026 view: if you installed in 2025, spend the hour checking your paperwork—you could recover up to $2,000. If you’re shopping now, budget without incentives and treat any utility rebate as a bonus.
Frequently Asked Questions
Do mini splits qualify for a tax credit in 2026?
No. Section 25C ended for property placed in service after December 31, 2025 under the One Big Beautiful Bill Act. Utility rebates remain available in Florida, and the state HEAR program has not launched.
Can I still claim the mini split tax credit for a 2025 Florida installation?
Yes, on your 2025 federal return. If you already filed without it, amend using Form 1040-X. If you filed an extension, claim it by October 15, 2026. You need Form 5695 Part II and the manufacturer’s four-character code.
Are Florida HEAR rebates available for a mini split right now?
No. FDACS administers Florida’s HEAR program and the portal states the pilot is expected to launch in the future. Registration is the only step available. Rebates are not paid retroactively for work finished before a program opens.
Your Next Step Depends on When You Installed
Installed in 2025? Gather your itemized invoice, AHRI certificate, and manufacturer certification code. If the code is missing, contact the manufacturer—you may still qualify for up to $2,000.
Shopping in 2026? Call your utility before hiring an installer. FPL, Duke Energy Florida, TECO, JEA, and OUC require pre-approval. Check the Florida Energy Saver portal for HEAR updates. Choose ENERGY STAR equipment with ≤700 GWP refrigerant, a variable-speed inverter compressor, and a heat pump. Filterbuy ductless systems use R-32 and variable-speed inverter technology. See our mini split selection guide for sizing and SEER2.
Finally, follow a Florida maintenance schedule and keep the filter clean to maintain efficiency.
