Pump Up the Savings with Federal Energy Tax Credits

Federal Tax Credits for Heat Pump Upgrades: What Homeowners Need to Know in 2026

Federal tax credits for heat pump upgrades let qualifying homeowners claim 30% of eligible installation costs on their federal tax return, up to $2,000 per year for qualifying air-source systems. If you installed a heat pump in 2025, you can generally claim this credit when you file your 2025 taxes in 2026.

Here is a quick summary of what is available:

Key facts at a glance:

• No income limits to qualify
• Credit is non-refundable and reduces your tax bill, but not below zero
• Equipment must meet ENERGY STAR Most Efficient or CEE highest efficiency tier requirements, as applicable
• Must be installed in an existing home
• The total annual cap across all home improvement credits is $3,200 for Section 25C improvements

These credits come from the Inflation Reduction Act of 2022, and they have helped many households offset qualifying energy-efficiency upgrades.

For Kansas homeowners in communities like Leavenworth, Basehor, and Tonganoxie, federal credits may become even more valuable when paired with available state or utility incentives. The details matter, and it helps to understand the rules before filing.

This guide walks through the basics, including which systems qualify and how homeowners typically report the credit using IRS Form 5695.

Why 2025 installs still matter in 2026

The credit is tied to the tax year the system was installed and placed in service, not the year you prepare your return.

So if your heat pump was installed and operating by Dec. 31, 2025, you may claim the credit when you file your 2025 federal return in 2026. If installation moved into 2026, that falls under a different tax year with its own eligibility review.

For most homeowners, "placed in service" means the system was fully installed and ready for normal use in the home. A signed contract or deposit alone is not enough.

You will generally claim the credit using IRS Form 5695 and then transfer the allowed amount to your Form 1040.

The two federal tax credits homeowners ask about most

There are two federal credits most homeowners mean when they search for federal tax credits for heat pump upgrades:

• Section 25C for air-source heat pumps, including many central systems and ductless mini-splits
• Section 25D for geothermal heat pumps, also called ground-source systems

Both can equal 30% of qualified costs, but they work differently:

• Section 25C has a $2,000 annual cap for heat pumps and shares an overall yearly limit with other home-efficiency upgrades.
• Section 25D offers a 30% credit with no annual dollar cap for geothermal systems and remains available through 2032.

That difference can significantly affect how much credit a homeowner may be able to claim for a qualifying project.

Which Federal Heat Pump Credit Applies to Your Project?

The right credit depends mainly on the type of heat pump installed and how the home is used.

Section 25C: federal tax credits for heat pump upgrades using air-source systems

Section 25C is the credit most homeowners ask about when considering an air-source heat pump, whether that means a ducted system or a ductless mini-split.

Under Section 25C in 2025:

• The credit equals 30% of qualified costs
• The heat pump portion is capped at $2,000 per year
• The broader annual limit for all 25C improvements is $3,200
• The home must be an existing home
• New construction does not qualify
• There are no income limits

This credit generally applies to systems installed in a residence used by the taxpayer. Some guidance indicates that second homes and, in certain situations, renters may qualify for 25C improvements in an existing residence they use. Homeowners should pay close attention to how the property is used and whether the improvement is for personal residential use rather than a purely rental property.

Section 25D: federal tax credits for heat pump upgrades using geothermal systems

Section 25D is different. It applies to geothermal heat pumps and falls under the residential clean energy credit.

Key points for geothermal in 2025 and beyond:

• Credit equals 30% of qualified costs
• No annual dollar cap
• Available through Dec. 31, 2032
• Applies to geothermal heat pump systems installed in qualifying residences
• Unused credit may generally carry forward to future tax years

This is one of the biggest differences between 25C and 25D. If a homeowner cannot use the full geothermal credit in one year because their tax liability is lower than the credit amount, the unused portion may generally be carried forward. That carryforward is not available for Section 25C.

Who can claim the credit and who cannot

In simple terms, to claim one of these credits you usually need:

• A qualifying heat pump
• A qualifying residence
• A completed installation in the proper tax year
• Federal income tax liability to offset
• Records showing the equipment and installation qualify

Who may qualify, depending on the credit and property use:

• Homeowners living in existing homes
• Some second-home owners for qualifying residential use
• Some renters under 25C for improvements they paid for in an existing residence they use

Who generally cannot claim it:

• People installing systems in new construction under these rules
• Property owners claiming it for property used only as rental property
• Taxpayers with no federal tax liability expecting a refund from the credit alone
• Anyone with nonqualifying equipment or incomplete records

If your situation is unusual, such as mixed personal and rental use, it is smart to confirm details with a tax professional.

2025 Eligibility Rules for Qualifying Heat Pumps

Not every heat pump qualifies. The federal government did not say, "If it hums and blows air, good enough." Equipment must meet specific efficiency standards.

For 2025, the safest approach is to verify that the exact model is listed as eligible through one of the recognized paths:

• ENERGY STAR Most Efficient
• ENERGY STAR Cold Climate pathway for certain applications
• CEE highest efficiency tier, where applicable
• Manufacturer certification statement
• AHRI matched-system documentation

Air-source heat pump efficiency standards for 2025

For air-source systems in 2025, qualifying rules became more straightforward than in prior years.

Important 2025 points:

• No regional restriction applies the way earlier Northern and Southern tier standards did
• Eligible units generally must meet ENERGY STAR Most Efficient requirements
• Some 2025 guidance also recognizes a Cold Climate pathway for heating-dominated applications
• Ducted split systems, packaged systems, and ductless mini-splits can qualify if the exact system meets the standard

That last point matters a lot. Tax-credit eligibility is not just about the outdoor unit brand or brochure. It is often about the matched system, including indoor components. The AHRI certificate and manufacturer documentation help confirm that the installed combination qualifies.

How SEER2, EER2, and HSPF2 affect federal tax credits for heat pump upgrades

These ratings are shorthand for efficiency performance:

• SEER2 measures cooling efficiency over a season
• EER2 measures cooling efficiency at a specific condition
• HSPF2 measures heating efficiency over a season

Higher numbers generally mean better efficiency, but the tax credit is not awarded simply for "high enough sounding" numbers. The actual unit or matched system must satisfy the applicable 2025 eligibility standard.

Earlier guidance referenced regional thresholds such as:

• Northern tier units with EER2 above certain minimums
• Southern ductless or mini-split thresholds such as SEER2 above 16, EER2 above 12, and HSPF2 above 9

For 2025, the bigger takeaway is that ENERGY STAR eligibility pathways replaced much of the old regional confusion. That is good news for homeowners because it is easier to verify the exact model using official listings and manufacturer certifications.

What changed from earlier years

Compared with prior years, 2025 brought a few changes that matter:

• Regional standards were effectively phased out for practical consumer verification
• ENERGY STAR Most Efficient and Cold Climate pathways became the easier test to follow
• Manufacturer identification codes became more important for tax filing
• Documentation expectations tightened

So if you remember older advice about Northern versus Southern requirements, do not assume it still controls your 2025 return. Verify based on the 2025 eligibility pathway for the exact model installed.

Credit Amounts, Annual Limits, and Stacking Other Incentives

A qualifying air-source heat pump under Section 25C can earn a credit equal to 30% of qualified costs, including installation labor, up to the annual cap. Geothermal under Section 25D also uses 30%, but without the same annual cap.

Many homeowners who switch to a heat pump also look for long-term efficiency benefits in addition to potential tax savings. Actual utility savings depend on the home, equipment selection, ductwork, thermostat settings, and local utility rates.

Maximum tax credit amount and the $3,200 annual limit

For Section 25C in 2025:

• Heat pumps can qualify for up to $2,000 per year
• Other eligible home improvements can qualify for up to $1,200 combined
• Total annual 25C limit is $3,200

That means if you install a qualifying air-source heat pump and also make other eligible improvements in the same year, you may be able to claim more than just the heat pump credit, but you still must stay within the category caps.

Other upgrades that share the same yearly bucket

Other improvements that can fall into the 25C annual structure include:

• Insulation and air sealing
• Exterior windows and skylights
• Exterior doors
• Electric panel upgrades that enable qualifying equipment and meet code requirements
• Heat pump water heaters
• Home energy audits

A practical example:

• A homeowner installs a qualifying air-source heat pump
• The same year, they also complete insulation work or an eligible panel upgrade
• The heat pump has its own cap
• The other improvements share the separate $1,200 bucket
• The combined annual 25C total cannot exceed $3,200

Can you combine federal credits with rebates and programs?

Yes, in many cases you can combine federal tax credits with:

• State rebates
• Utility incentives
• Manufacturer promotions
• Programs such as HEEHRA or HOMES, where available and applicable

But there is an important rule: rebates that reduce your out-of-pocket cost may also reduce the amount used to calculate the federal credit. In plain English, you usually do not claim a tax credit on money already paid on your behalf.

Best practices include:

• Subtract applicable rebates from the project basis when required
• Keep proof of the rebate amount and source
• Save all invoices and final accounting documents
• Confirm program-specific stacking rules before filing

How to Document and Claim the Credit Correctly

Tax credits are generous. Tax paperwork is less charming. Good records make the process much easier.

To claim the credit correctly, you will generally want a complete file showing what was installed, when it was installed, and why the exact system qualifies.

What paperwork to keep for federal tax credits for heat pump upgrades

Keep copies of:

• Itemized receipts
• Installation invoices showing labor
• Product model numbers
• Manufacturer certification statement
• AHRI certificate or matched-system documentation
• Proof of installation date and placed-in-service date
• Any rebate paperwork
• The Qualified Manufacturer Identification Number or PIN, if provided

A common recommendation is to keep tax-related records for at least three years in case of questions or audit support.

If your system needs service records later, our heat pump service in Leavenworth, KS page has more information about ongoing support.

Where to find the QMID or PIN and why it matters for 2025 returns

For 2025 returns filed in 2026, manufacturers may provide a Qualified Manufacturer Identification Number, sometimes called a QMID, QM code, or PIN, to help verify eligibility.

You may find it on:

• The manufacturer certification sheet
• Product eligibility pages on the manufacturer website
• Dealer or installer paperwork
• Tax software prompts asking for a manufacturer code

Why it matters:

• It helps the IRS verify that the claimed equipment is a qualifying product
• It supports the claim if the model is later questioned
• Missing it can create unnecessary delays or confusion

The exact name can vary by source, but the practical point is the same: do not throw away the paperwork with the code on it.

How to file IRS Form 5695 step by step

At a high level, most homeowners claiming a 25C heat pump credit will:

1. Gather invoices, certifications, and manufacturer code information.
2. Complete the appropriate section of IRS Form 5695, usually Part II for energy-efficient home improvement credits.
3. Enter qualified expenses based on the rules for the specific equipment.
4. Apply the credit limitations.
5. Transfer the allowed credit amount to the appropriate line of Form 1040.

A few helpful reminders:

• You do not need to itemize deductions to claim this credit
• Standard deduction filers can still claim it
• Tax software may ask for the model, manufacturer, and code information
• If you received rebates, you may need to reduce the amount used for the calculation

Are these credits refundable, and is unused credit lost?

For Section 25C:

• The credit is nonrefundable
• It can reduce your federal income tax to zero
• It cannot create a refund beyond your tax liability from the credit alone
• Unused 25C credit does not carry forward

For Section 25D geothermal:

• The credit is also nonrefundable
• But unused amounts may generally carry forward to future tax years

That means if your 25C credit is larger than your tax owed, the extra portion is usually lost. For geothermal under 25D, unused credit may still help in a later year.

Frequently Asked Questions About Federal Tax Credits for Heat Pump Upgrades

By what date must a heat pump be installed to qualify for the 2025 credit?

For the 2025 credit under Section 25C, the heat pump must be installed and placed in service by Dec. 31, 2025. You would then claim it when filing your 2025 federal return in 2026.

Are there income limits or restrictions for claiming the credit?

There are no income limits listed in the research for claiming these heat pump credits. However, there are still restrictions:

• You must have federal tax liability for the credit to help
• The property must meet residence-use rules
• The equipment must qualify
• New construction is excluded for this credit discussion
• Personal-use rules matter for second homes and rental situations

Can renters or second-home owners claim a heat pump tax credit?

In some cases, yes.

For Section 25C, industry guidance referenced in the research indicates:

• Renters may qualify for eligible improvements they pay for in an existing residence they use
• Second homes may also qualify if they are used as residences and meet the program rules

For Section 25D geothermal:

• Second homes used as residences may qualify
• Pure rental properties generally do not qualify in the same way for personal residential credits

Because ownership and use rules can get technical, mixed-use and landlord situations should be reviewed carefully before filing.
