The federal 30% tax credit that used to make home batteries a lot cheaper is gone for new cash or loan purchases starting January 1, 2026. This guide explains what happened, who might still be able to claim it, and the state and utility programs still worth checking. This is general information, not tax advice — confirm your own situation with a tax professional.

The short version: a law passed in mid-2025 cut short a federal credit that was originally scheduled to run for years longer.
Signed into law on July 4, 2025, the OBBBA terminated the Section 25D Residential Clean Energy Credit — the credit that covered 30% of the cost of solar and battery storage systems — nearly a decade ahead of its original 2034 sunset.
Best for: Understanding why the credit disappeared.
The catch: This affects systems you buy outright with cash or a loan, not every ownership structure.
Starting January 1, 2026, homeowners who purchase a battery storage system outright can no longer claim the 30% federal Section 25D credit on that purchase.
Best for: Anyone budgeting a 2026 battery purchase — plan without this credit.
The catch: Don't assume a quote that mentions "30% federal credit" is current — some marketing hasn't caught up.
If your battery system was installed and placed in service during 2025, you may still be able to claim the 25D credit using IRS Form 5695 on your 2025 federal tax return, due April 15, 2026 (extensions available to October 15, 2026).
Best for: Homeowners who installed a battery in 2025 and haven't filed yet.
The catch: Eligibility depends on your exact install and service date — confirm with a tax professional.
The residential credit is gone, but it isn't the only incentive path. Availability varies by state, utility, and how you finance the system.
The commercial investment tax credit under Section 48E can still apply to battery systems that are owned or leased by a third party (rather than owned outright by the homeowner), and it's currently available through 2032.
Best for: Homeowners open to a lease or third-party-ownership arrangement.
The catch: You don't own the system yourself, which changes the economics — compare total cost carefully.
Some states still fund their own battery rebates. California's Self-Generation Incentive Program (SGIP) is a widely cited example that pays per kWh of installed battery capacity, independent of the federal credit.
Best for: Homeowners in states that still run an active program.
The catch: Programs, funding levels, and waitlists vary by state and change over time — check your state's current status.
Some utilities run VPP programs that aggregate home batteries to help the grid at peak times, paying participating households roughly $500–$1,500 a year in some higher-value markets.
Best for: Homeowners who already have or are considering a battery and want ongoing payments, not a one-time credit.
The catch: It's an ongoing enrollment, not a purchase discount, and payouts vary a lot by utility and region.
Get quotes that reflect current 2026 incentive rules, ask installers directly whether any third-party-ownership or state/utility program applies to you, and confirm everything with a tax professional before you file.
