Homeowners can no longer claim the federal Residential Clean Energy Credit under Section 25D for a battery system placed in service after December 31, 2025. For 2026 installations, the realistic federal pathway runs through third-party ownership and Section 48E, where a developer or lessor claims the credit and passes savings to you through a lease or power purchase agreement. If your battery was fully installed in 2025 and met the 3 kWh threshold, you can still file Form 5695 and carry forward any unused credit.
TL;DR:
- The residential clean energy credit is unavailable for batteries placed in service after December 31, 2025, unless installation was completed in 2025 with proper documentation.
- Only fully installed and inspected systems by the end of 2025 qualify, with proof including invoices, interconnection approval, commissioning reports, and final inspection.
- Batteries must have a capacity of at least 3 kilowatt-hours to qualify for the 30% credit, covering equipment, labor, and interconnection costs for permanent installations.
- For 2026, third-party ownership through Section 48E remains the main federal pathway, with savings passed to homeowners via lease or PPA agreements.
- State and utility incentives can still add value but typically reduce the federal credit basis, so homeowners should verify rebate amounts before purchase.

What Changed: The 2025 Legislative Shift and IRS Interpretation
The One Big Beautiful Bill, signed into law as Public Law 119-21, accelerated the termination date for several residential energy credits, including the Residential Clean Energy Credit under Section 25D. Before this law, the credit was scheduled to phase down gradually through 2034. Instead, IRS guidance on the OBBBA changes confirms the credit is unavailable for any battery storage system or other qualifying energy property placed in service after December 31, 2025.
The distinction that matters here is "placed in service," not "purchased" or "contracted." The IRS treats an expenditure as made when the original installation is completed, meaning a signed contract or a deposit paid in 2025 does not secure eligibility if the system is not fully operational until 2026. This single definition decides who qualifies and who does not.
For homeowners who completed installation in 2025, eligibility still stands, provided you can document it. The IRS guidance points to a few things that matter most when proving your system qualifies:
- Completion date: The system must have passed final inspection and been fully installed, not merely delivered or partially wired.
- Interconnection and commissioning: Utility interconnection approval and a commissioning report help establish the actual placed-in-service date.
- Paid invoices: Costs must be paid, not just invoiced, for the expenditure to count toward the 2025 tax year.
If your paperwork clearly shows completion before the end of 2025, the credit remains available to you even though you file in the 2026 tax season.
Section 25D Eligibility and the 3 kWh Rule for Qualifying Batteries
For systems installed and placed in service in 2025, the Residential Clean Energy Credit required batteries to meet a specific technical threshold. Under the Form 5695 instructions, qualified battery storage technology needed a capacity rating of at least 3 kilowatt-hours to count toward the 30% credit.
The Residential Clean Energy Credit covered 30% of qualifying costs for battery storage technology rated at 3 kWh or higher, according to Form 5695 guidance, and that 30% rate applied through the end of the 2025 tax year before accelerated termination took effect.
Qualifying costs went beyond the battery unit itself. The credit basis included:
- Equipment costs: The battery modules, inverter components tied to storage, and racking or mounting hardware.
- Labor for installation: Onsite preparation, assembly, and the electrician's work connecting the system to your home's panel.
- Interconnection expenses: Costs tied to connecting the battery to the utility grid or integrating it with an existing solar array.
A permanent home installation, wired into your electrical system and inspected by your local authority having jurisdiction, is what the credit was designed to cover. A portable power station or a battery that is not permanently installed and interconnected does not meet the same bar, even if its capacity exceeds 3 kWh. This distinction trips up a fair number of homeowners who assume any battery purchase qualifies.
How to Claim the Credit for a Qualifying 2025 Installation
If your battery system was placed in service in 2025, claiming the credit follows a defined process built around Form 5695. Here's the sequence:
-
Gather your paid invoices and installation records, separating equipment and labor costs tied specifically to the battery storage system.
-
Complete Part I of Form 5695, entering your qualified battery storage costs alongside any solar, geothermal, or other clean energy property costs from the same tax year.
-
Calculate your credit using the worksheet in the form instructions, which applies the 30% rate to your total qualifying costs.
-
Compare the credit against your tax liability. Because the credit is nonrefundable, it only offsets taxes you actually owe for that year.
-
Carry forward any unused amount. Form 5695 instructions allow you to carry an unused credit forward to the following tax year, which means a 2025 credit you can't fully use gets reported again when you file for 2026 and, if needed, into 2027.
Pro Tip: Keep a dedicated folder with your signed contract, final invoice, inspection certificate, and utility interconnection approval. These four documents cover almost every question the IRS might ask if your filing gets a closer look.
Common mistakes include claiming costs for a battery that never received permanent interconnection, mixing up the placed-in-service date with the purchase date, and forgetting to carry forward an unused balance onto the next year's return. Double-check that the capacity rating on your installer's documentation explicitly states 3 kWh or more, since that figure is often buried in a spec sheet rather than stated plainly on the invoice.
Section 48E and Third-Party Ownership: The Remaining Federal Pathway
With Section 25D closed to new homeowner-owned installations, Section 48E, the Clean Electricity Investment Credit, becomes the practical route to federal value in 2026. This credit is claimed by the entity that owns the energy property, typically a developer, installer, or leasing company, rather than by the homeowner directly.
Here's how that translates into savings for you:
- Lease and PPA structures: A developer owns the battery system, claims the 30% credit under Section 48E, and passes some of that value to you through lower monthly lease payments or a reduced rate on power purchased from the system.
- No direct homeowner claim: You will not file Form 5695 for a leased or PPA-financed system, since you don't own the underlying property.
- Eligibility window: Section 48E remains available for qualifying projects through 2032, giving third-party-owned systems a longer runway than the homeowner-owned credit had.
Projects need to meet construction-start safe harbor rules to lock in credit terms, and prevailing wage and apprenticeship requirements can add value for larger commercial-scale projects, though these adders matter more to the developer's economics than to your monthly bill. Domestic content provisions may also factor into a developer's equipment sourcing decisions. None of this changes your tax filing, but it does affect how much savings a lease or PPA offer can realistically pass through, so it's worth asking a prospective installer how their financing structure accounts for these federal mechanics.
State and Utility Incentives: Stacking Value After the Federal Shift
With the homeowner-owned federal credit gone for 2026 installs, state and utility programs carry more weight than they used to. Programs like California's Self-Generation Incentive Program and New York's NYSERDA incentives have historically offered rebates for qualifying battery storage, and many utilities run their own rebate or demand-response programs that pay homeowners for battery participation.
Multiple state and utility programs continue to offer incentives that can stack with federal credits, though the rules for how they interact matter for your bottom line. An upfront rebate from a state or utility program generally reduces the basis you can claim under a federal credit, because the IRS calculates the credit on your net cost after rebates, not your gross purchase price.
For a 2025 installation that still qualified for Section 25D, this meant a $2,000 utility rebate on a $15,000 battery system would reduce your federal credit basis to $13,000, producing a $3,900 credit instead of $4,500. The math changes project by project, so this is illustrative only.
- Check your state energy office for current program status, since several programs have funding caps that close enrollment mid-year.
- Call your utility's demand-response or storage rebate line directly, as program terms shift more often than state program pages get updated.
- Ask any installer for a written rebate estimate before signing a contract, since rebate amounts affect your total project cost and any remaining federal credit calculation.
Documentation and Timeline Checklist for Proving Placed-in-Service Status
Whether you're confirming a 2025 installation or planning a 2026 lease, a clear paper trail protects you if your return gets questioned. Prioritize these documents:
- Paid invoices showing the final cost breakdown between equipment and labor.
- Final inspection sign-off from your local authority having jurisdiction.
- Interconnection approval from your utility, dated and signed.
- Commissioning report confirming the system was operational.
- Signed contract showing the original agreement date, useful context even though it doesn't determine eligibility on its own.
On timing, the IRS looks past your purchase contract or deposit date and focuses on when the system was actually completed and operational. A few key dates to track:
- 2025 installation window: Systems completed and placed in service by December 31, 2025 remain eligible for the 30% credit.
- 2026 filing season: You'll report a qualifying 2025 installation on your return filed in early 2026.
- Carryforward deadline: Any unused credit amount carries forward to the following tax year, so track it carefully if your 2025 liability was too low to absorb the full credit.
Planning Advice: Buy, Lease, or Wait?
Deciding how to move forward in 2026 depends on your situation. If you already completed a 2025 installation, filing for the credit is straightforward. If you're starting fresh in 2026, the choice between buying outright or exploring a lease or PPA now hinges on which structure captures more value for your household.
Ownership still makes sense if you want full control over the system, plan to stay in your home long term, and can finance the upfront cost without relying on a federal credit that no longer applies. A lease or PPA tends to deliver better near-term value specifically because the developer can claim Section 48E and pass part of that savings along.
Sizing matters regardless of ownership model. A proper whole-house load analysis identifies your critical loads, your daily usage pattern, and how much runtime you actually need during an outage, rather than sizing based on a generic package.
Pro Tip: Ask any installer for UL 9540 certification on the battery system and confirm their AHJ approval history in your area before signing.
Prime Microgrid Perspective on the Policy Shift
We see the end of Section 25D for new installs as a shift in where the value comes from, not a reason to delay a resilience decision. Homeowners who documented a 2025 installation correctly are in good shape. For everyone deciding now, we lean toward conservative contracting: get clear written terms, confirm whether a lease or PPA structure is passing through real federal value, and keep every inspection and interconnection record from day one. Site-specific tax questions still belong with a qualified tax professional.

FAQ
Is there still a 30% solar tax credit in 2026?
No. The federal Residential Clean Energy Credit, which offered 30% for solar and battery storage, ended for property placed in service after December 31, 2025, under OBBBA's accelerated termination. Homeowners pursuing solar or battery storage in 2026 need to look at third-party ownership models or state and utility incentives instead.
Is there still a tax credit for home battery backup?
For homeowner-owned systems placed in service in 2026 or later, no federal credit applies under Section 25D. A battery system financed through a lease or power purchase agreement may still carry federal value, since the developer can claim Section 48E and pass savings to you.
How does the 30% federal tax credit for solar work?
Historically, the credit let homeowners claim 30% of qualifying costs for solar and battery storage property completed by December 31, 2025, filed on Form 5695. The credit was nonrefundable, meaning it only offset taxes owed, with any unused portion carried forward to future years.
Why are people getting rid of solar panels?
This isn't a widely documented trend tied to tax policy, and there's no authoritative data suggesting homeowners are removing existing solar systems because of the Section 25D termination. The policy change affects new installations going forward, not systems already placed in service.
