Battery Storage Tax Credits After 2025: The Real 2026 Rules

Battery storage has become the defining story of post-OBBBA solar. In the first quarter of 2026, a record 45% of residential solar installations were paired with a battery — and with net metering under pressure in many states, storage is no longer an optional add-on but the central piece of the financial case. So it's no surprise that the question we hear most is: does a battery still get a federal tax credit after the residential solar credit expired? The answer follows the same 25D-versus-48E split as solar itself — and ownership is everything.

The Short Answer

Yes, battery storage can still qualify for a 30% federal credit — but only under Section 48E, and only through the right ownership model. If you buy and own a battery for your primary residence, the old Section 25D path is gone. If youlease the battery, sign a PPA, or install it on a commercial or rental property, the 30% Section 48E credit still applies for projects that began construction beforeJuly 4, 2026 (a Saturday; under IRC 7503 the effective deadline rolled to Monday, July 6, 2026 — now passed). For the broader credit backdrop, see ourcomplete 2026 tax-credit guide.

Owned Battery Storage: The 25D Path Is Closed

Under the now-expired Section 25D, owned residential battery storage of at least 3 kWh qualified for the 30% personal tax credit — claimed by the homeowner on IRS Form 5695 — as long as the system was placed in service on or beforeDecember 31, 2025. According to theIRS, the credit is not available for property placed in service after that date. That means if you purchase and own a new battery for your primary residence in 2026, there is no federal tax credit available to you for it. Plan for the full equipment and installation cost.

One important grandfathering note: if your owned battery wasplaced in service by December 31, 2025 — installed, interconnected, and operating — you remain eligible for the 30% 25D credit on that system. File Form 5695 with your return.

Leased and PPA Battery Storage: 48E Still Applies

This is where storage gets interesting. UnderSection 48E, the Clean Electricity Investment Credit, battery storage still qualifies at 30% — and unlike the narrow 25D residential rule, 48E explicitly coversstandalone storage as well as storage paired with solar. The catch is that 48E is a business credit, so it flows through an eligible ownership structure:

• Lease or PPA: The installer or developer owns the battery and claims the 30% 48E credit on IRS Form 3468. They pass part of the value to you through lower monthly payments. You file nothing related to the credit.
• Rental or commercial property: You claim the 48E credit directly on your business return, and the battery may also qualify for MACRS depreciation plus bonus depreciation.
• Tax-exempt entities (nonprofits, schools, municipalities): can elect direct pay to receive the credit value as a cash payment from the Treasury.

All 48E projects share the same hard requirement: construction had tobegin before July 4, 2026 — satisfied either by the Physical Work Test or by the 5% expenditure safe harbor, which wasRESTORED on June 6, 2026 when a federal court vacated IRS Notice 2025-42 (Oregon Environmental Council v. IRS, No. CV-25-4400; the IRS may appeal) — and the system must be placed in service within four years of that start. That July 4, 2026 construction-start deadline has now passed, so only grandfathered pre-deadline projects can still claim 48E. FEOC (Foreign Entity of Concern) compliance also applies — panels or batteries from prohibited manufacturers can disqualify the credit.

Paired vs Standalone Storage

A common point of confusion is whether the battery needs to be attached to solar. Historically, residential storage under 25D had to be charged primarily by renewables to qualify. Under 48E, the rules are broader: both paired solar-plus-storage and standalone battery systems can qualify for the 30% credit, as long as the ownership and construction-start requirements are met. In practice, most homeowners still pair storage with solar because the economics are strongest when the battery is charged by free daytime production and discharged during expensive peak evening hours — especially on time-of-use rates where peak pricing now stretches late into the evening.

Whether paired or standalone, the ownership model determines the credit, not the hardware configuration. To model the payback difference for your situation, use theBattery Payback Calculator.

State Battery Incentives Still Apply

With the federal owned-residential credit gone, state and utility battery programs matter more than ever — and several stand out. These are among the most consequential still available (always verify current program status with your utility and theDSIRE database):

• California — SGIP (Self-Generation Incentive Program): rebates for residential storage, with larger incentives for equity-tier and low-income customers.
• Maryland — Residential Clean Energy Rebate:up to roughly $7,500 for battery storage systems.
• Oregon — Solar + Storage Rebate Program:incentives for residential solar PV paired with battery storage.
• Nevada — NV Energy Storage Incentive: a utility rebate for grid-tied batteries.
• New York — NYSERDA: upfront incentives for residential storage, plus ongoing compensation through the VDER tariff for grid exports.
• Massachusetts — ConnectedSolutions:performance-based payments for dispatching your battery during peak grid events.
• Hawaii — Battery Bonus: an upfront incentive for adding storage to rooftop solar.

A growing number of these programs are structured asVirtual Power Plant (VPP) arrangements, where the utility pays you to draw on your battery during peak demand. VPP income can materially shorten a battery's payback — find programs near you with ourVPP Program Finder.

Why Storage Economics Improved Even as the Credit Shrank

It seems paradoxical that battery adoption hit a record in Q1 2026 even as the owned-residential credit disappeared. The explanation is threefold. First, net metering rollbacks (most prominently California's NEM 3.0) slashed the value of exporting surplus solar, making self-consumption — and therefore storage — far more valuable than selling back. Second, the shift tolease/PPA financing means more batteries are installed under 48E, where the credit still lives. Third,time-of-use rates widened the gap between cheap midday power and expensive evening power, increasing the arbitrage a battery captures every day.

The result is that for many homeowners in reformed-net-metering states, the question is no longer "solar with or without a battery?" but "how big a battery?" The federal credit picture is narrower, but the underlying economics of storage are stronger than they have ever been.

Where Storage Credits Still Apply

After 2025, owned residential battery storage lost its direct federal credit — but storage did not lose its appeal, and it did not lose every credit. Leased and PPA batteries still earn 30% under Section 48E, standalone storage qualifies, and a deep bench of state rebates and VPP programs now carries much of the load the federal credit used to. If you are buying storage in 2026, price it as a lease/PPA versus an owned system, stack every state incentive, and treat the federal 30% as available only through the right ownership structure — not as a given.
