Is the 30% Federal Solar Battery Tax Credit Available in 2026?
Learn the status of the 30% federal solar battery tax credit in 2026. Compare Section 25D expiration rules, lease options, and Form 5695 filing.
Navigating clean energy incentives requires careful attention to active legislation. For several years, homeowners planning solar-plus-storage upgrades could count on a reliable 30% federal tax credit under Section 25D of the Internal Revenue Code. However, recent legislative changes have drastically altered this incentive program.
If you are preparing to install home battery backup storage, you must distinguish between outdated online advice and the active regulatory landscape. While many solar sales websites still advertise a 30% tax credit extending through 2032, homeowners purchasing batteries with cash or loans face a very different set of rules. Here is our regulatory-accurate guide to the 30% solar battery tax credit.
The July 2025 OBBBA Law and Section 25D Expiration
The primary federal incentive for residential clean energy installations—the Section 25D Residential Clean Energy Credit—experienced an early termination. Under the One Big Beautiful Bill Act (OBBBA) passed in July 2025, Congress accelerated the expiration dates of several consumer tax credits.
As a direct result, the Section 25D 30% credit officially expired on December 31, 2025, for homeowner-purchased systems. Any residential battery system installed and placed in service on or after January 1, 2026, using cash, home equity lines of credit (HELOCs), or solar loans is no longer eligible for this federal tax reduction.
Who Can Still Claim the 30% Battery Tax Credit?
Despite the expiration of direct purchasing incentives, there are still two legal pathways to claim or benefit from the 30% tax credit:
1. Systems Installed & Placed in Service Before 2026: If your home battery system was physically wired and activated on or before December 31, 2025, you remain fully eligible to claim the 30% credit on your federal tax return. You must file IRS Form 5695 alongside your standard Form 1040.
2. Third-Party Leases & Power Purchase Agreements (PPAs): The early expiration under the OBBBA only targeted the residential consumer credit (Section 25D). It did not terminate the commercial clean energy credit (Section 48E). When you lease a battery system, the solar developer retains system ownership and claims the 30% commercial credit, passing the savings down to you via lower monthly payments.
Credit Expiration Date
The Section 25D residential tax credit is completely inactive for homeowner-purchased systems (cash or solar loans) installed on or after January 1, 2026. Do not let solar sales agents claim you can deduct 30% of your cash system cost on your federal taxes this year.
How to Claim Past Installations on IRS Form 5695
If you are filing taxes for a qualifying battery system placed in service on or before December 31, 2025, follow these filing steps:
IRS Form 5695 Part I: Navigate to the residential clean energy credit section. Enter your total battery storage project costs (including equipment, smart gateway, permit fees, and labor) on Line 5 (Residential clean energy property costs).
Capacity Limit Rules: To qualify for the credit, the battery must be installed in a home located in the United States and must have a rated capacity of at least 3 kilowatt-hours (kWh). All major brands (Tesla Powerwall, Enphase IQ, FranklinWH) exceed this minimum threshold.
Non-Refundable Carry-Forward: The credit is non-refundable, meaning it can reduce your tax liability to zero, but will not yield a cash refund check for any excess. However, any unused credit rolls over to the following tax year.
Active 2026 Alternatives: State Rebates & Utility Incentives
Since cash purchases no longer receive federal tax offsets, state programs and utility rewards are now the primary way to reduce upfront costs:
California SGIP: The Self-Generation Incentive Program offers direct rebates for LFP battery installations, with higher rebate tiers for homeowners living in high-fire-risk zones or low-income communities.
Maryland Storage Tax Credit: Offers a direct state income tax credit covering 30% of energy storage equipment costs, capped at a maximum of $5,000 per residential system.
Utility Virtual Power Plants (VPPs): Utilities credit you for exporting battery power during grid stress, generating $500 to $1,500 in annual recurring savings.
Federal Tax Credit Status Summary
The table below compares federal tax credit eligibility based on installation dates and funding methods:
Federal Battery Tax Credit Blueprint
| Cash / Loan Purchase (Installed in 2026 or later) | Credit Status: Expired (0% Credit) | Claim Form: N/A |
| Third-Party Lease / PPA (Installed in 2026 or later) | Credit Status: Active (30% offset passed to lease rates via Sec 48E) |
| Past Purchase (Installed on or before Dec 31, 2025) | Credit Status: Active (30% Credit) | Claim Form: IRS Form 5695 |
Sizing and ROI Recommendations
The expiration of the Section 25D cash tax credit has changed the optimal financing structure for home energy storage. While cash purchases no longer qualify for federal offsets, third-party leases and Power Purchase Agreements (PPAs) remain highly viable, leveraging Section 48E commercial credits to lower monthly payments.

Common questions
Can I claim a battery tax credit if I don't have solar panels?
Yes, for qualifying historical systems. The 2023 IRA update removed the requirement that batteries charge from solar; stand-alone batteries are eligible, though subject to the December 31, 2025, residential purchase cutoff rules.
What happens if my tax liability is lower than my carry-over credit?
Because Section 25D is a non-refundable credit, it can reduce your tax liability to zero, but any remaining credit carries forward to the following tax year. It cannot be refunded in cash.
Will the federal battery tax credit be extended again?
Given the July 2025 OBBBA early termination, any future extensions would require major federal legislative action. State rebates and third-party leases will remain the dominant financing styles for the foreseeable future.
