Heat Pump Tax Credit for Homeowners: What to Verify in 2026

TL;DR: The federal Energy Efficient Home Improvement Credit for heat pumps has been amended repeatedly since it launched, most recently by the One Big Beautiful Bill Act (P.L. 119-21) in 2025, so a percentage or dollar cap you remember from a prior tax year may no longer apply. Check IRS Form 5695 instructions on IRS.gov before you buy — purchase date and placed-in-service date both matter under current law. If the equipment is going into a rental instead of your own home, this becomes a depreciation question rather than a credit question, and 100% bonus depreciation is now permanent for qualifying property acquired after Jan 19, 2025.

You've heard a heat pump can knock money off your tax bill, but the number you saw quoted a year or two ago might already be wrong. Congress has touched residential energy credits more than once since 2022, and the most recent overhaul landed in 2025. Here's how to find the real figures for your situation instead of relying on a number that's already stale.

Okoniq Property Hub logs the purchase date, invoice, and placed-in-service date for equipment like this, so you have the paper trail ready whenever a credit or depreciation claim asks for it.

What is the heat pump tax credit, and does it still exist in 2026?

It's a federal credit tied to installing qualifying energy-efficient equipment in your home, and whether it applies to your purchase depends entirely on the date you bought and installed the equipment. The underlying law — commonly discussed as the Energy Efficient Home Improvement Credit — has been reshaped by the One Big Beautiful Bill Act, P.L. 119-21, signed in 2025. That same law made other energy-related provisions permanent while ending others early, which is exactly why guessing at last year's percentage or cap is risky this year.

Rather than repeat a figure that may have changed, go to the current IRS Form 5695 instructions on IRS.gov before you sign a contract with an HVAC installer. Ask the installer for the manufacturer's certification statement and keep it with your invoice — you'll need documentation either way, whether the answer turns out to be a credit, no credit, or a partial-year credit tied to your closing date.

How is the credit different for landlords versus homeowners?

It isn't the same claim at all — a homeowner's personal-residence credit and a landlord's business deduction run through completely different parts of the tax code. If the heat pump is going into your own home, you're in credit territory (Form 5695). If it's going into a rental unit, you're in depreciation and repair-versus-capitalize territory instead, and the relevant question becomes whether to expense it immediately or recover its cost over time.

For rental property, one verified change matters a lot: 100% first-year bonus depreciation is now permanent for qualifying property acquired after January 19, 2025, under the same 2025 law. Landlords can also elect a lower percentage instead, per Notice 2026-11 interim guidance, if that fits their year better. Before deciding, run the purchase through a capitalize vs. expense decision tree — a heat pump is a capital improvement in nearly every case, but the depreciation method you choose still needs a documented decision. For background on how equipment depreciation rules have shifted recently, see bonus depreciation phase-down, which walks through what changed and why the old "phasing to 20%" story no longer applies.

| | Homeowner (primary residence) | Landlord (rental property) | |---|---|---| | Tax treatment | Personal tax credit, Form 5695 | Depreciation / capital improvement | | Key date | Placed-in-service date | Acquisition date (for bonus depreciation) | | Verify where | Current IRS Form 5695 instructions | Current bonus depreciation guidance | | Paperwork needed | Manufacturer certification + invoice | Invoice, contractor payment records, election statement |

What paperwork do you need to claim it — or depreciate it?

You need the invoice, the installer's certification paperwork, and proof of the date the equipment actually started running, not just the date you paid a deposit. For a homeowner credit, that documentation supports your Form 5695 entry. For a landlord depreciating the same equipment, it supports the depreciation schedule and survives an audit request years later — auditors routinely ask for exactly this kind of dated proof, as covered in what auditors ask for in a rental property audit trail.

If you're a landlord paying an HVAC contractor directly, remember that payment reporting rules changed too. The threshold for issuing a 1099-NEC to a contractor rises from $600 to $2,000 per payee for payments made on or after January 1, 2026 — payments made before that date still fall under the $600 threshold. Whether or not a 1099 is required, the income is still reportable by the contractor, and you still need the payment on your own books. See 1099-NEC vs 1099-MISC for landlords for which form applies and when.

How do you avoid mixing up credit rules across tax years?

The fix is simple: write down the exact date the equipment was installed and running, not the date you signed the contract or paid a deposit. Recent law changes have made purchase date and placed-in-service date the dividing line for several energy and depreciation provisions at once — bonus depreciation, the information-return threshold, and the energy credit itself all hinge on specific effective dates. A heat pump ordered in December and installed in January can land in a different rule set than one installed a few weeks earlier.

If your install spans a calendar year-end, get the invoice to state the completion date clearly, and confirm with your CPA which year's rules apply before you file. Don't assume the rule you read about last spring still holds — check IRS.gov again at filing time.

What if you already claimed the credit and later convert the home to a rental?

Converting a former primary residence into a rental changes your basis and depreciation calculations going forward, separate from whatever credit you claimed in the year of purchase. The heat pump itself doesn't need to be re-evaluated for the credit you already took, but its remaining value now enters your rental depreciation schedule under different rules than the ones that applied while it was your home. See converting a primary home to a rental for how basis is calculated at the point of conversion.

FAQ

Does the heat pump tax credit apply to rental properties?

No — the homeowner credit under Form 5695 applies to your primary or qualifying personal residence. A heat pump installed in a rental unit is handled through depreciation and capital-improvement rules instead, not the personal energy credit.

Can I claim a credit and depreciate the same heat pump?

Not for the same unit in the same use. A heat pump in your own home may qualify for the personal credit; a heat pump in a rental you operate as a business is depreciated instead. Confirm the distinction with a CPA if a property serves mixed use, such as a duplex where you live in one unit.

What's the difference between purchase date and placed-in-service date?

Purchase date is when you paid or signed a contract; placed-in-service date is when the equipment was installed and operational. Several current tax provisions, including bonus depreciation, key off placed-in-service or acquisition dates specifically, so the two dates can put you under different rules.

Where do I find the current credit percentage and dollar cap?

Check the current-year IRS Form 5695 instructions directly on IRS.gov, since the cap and percentage have changed more than once and are not fixed permanently in every version of the law. Your CPA can also confirm the figure that applies to your specific purchase date.

What happens if I install the heat pump right at year-end?

The tax year your installation counts toward depends on when it was placed in service, not when you paid for it. Get a dated completion certificate from your installer and hold onto it in case the credit or depreciation rule for that specific year differs from the one before or after it.
