New York’s Residential Battery Storage Tax Break Lapsed May 31 While a Broader Exemption Waits in Committee

On June 1, 2024, New York stopped charging sales tax on home battery installations. The exemption covered the full equipment cost and the installation labor, across both the state and local portions of the sales tax, for systems at one-, two-, and three-family homes.

The exemption carried a sunset written into the law: May 31, 2026. That date has now passed.

The extension. Governor Kathy Hochul’s FY2027 Executive Budget proposed pushing the residential sunset out to June 1, 2028. Whether that extension survived into the enacted budget had not been confirmed in public reporting. For a state that has built its grid plan around distributed storage, the lapse leaves a consumer incentive in administrative limbo while the paperwork is sorted out.

The commercial gap. The residential break, whatever its final status, only ever covered homes. Commercial energy storage in New York has never had a sales-tax exemption at all.

Environmental Advocates New York frames this as a question of parity. In the group’s account, the state already exempts residential and commercial solar equipment, along with commercial fuel cells, from sales tax, which leaves storage as the clean-energy technology the existing exemptions skipped. The point of a storage exemption, in that telling, is to match treatment the state has already extended elsewhere, not to invent a new subsidy.

The bill. Assembly Bill A313 would create a single state sales-and-use-tax exemption covering energy storage equipment for both residential and commercial uses, and it would authorize cities and counties to exempt their local portion as well. NYSERDA estimates the fiscal impact would be minimal. The amended text on the legislative calendar carries the designation A313A.

The bill is not new. Sponsored by Assemblymember Amy Paulin, it was introduced on January 8, 2025, then amended, and it now sits in the Assembly Committee on Ways and Means. Per LegiScan’s bill history, versions have been introduced in prior sessions going back several years. It has not passed either chamber.

Advanced Energy United reports that the 2026 legislature prioritized clean energy, including storage, in its budget work. Whether a commercial storage exemption was actually enacted remains unconfirmed, a status that sits awkwardly beside a standalone bill still parked in committee and a residential extension whose enacted status is also unconfirmed. The honest reading of the public record is that New York’s storage tax treatment is fragmented and in motion, with no single document yet settling where it lands.

The math. A sales-tax exemption is not a transformative subsidy. At roughly 4 to 8 percent of installed cost, it trims a few points off the upfront price of a battery. It does not, on its own, turn a marginal project into a financed one.

What it does is stack. The economic case for commercial storage in downstate New York rests on demand charges, the portion of a commercial electric bill tied to a building’s single highest spike in power draw. Those charges are high in Consolidated Edison territory and rising, and they are the revenue a battery captures by shaving peaks. Local Law 97, New York City’s carbon penalty on large buildings, adds a second reason to manage load. A cut of several points to the capital cost lands on top of both, shortening payback rather than creating it.

The commercial exemption matters more, dollar for dollar, than the residential one that just lapsed: the demand-charge value that justifies a battery is concentrated in commercial buildings, not homes. New York extended its storage break in the reverse order. Residential storage received a clean, if temporary, exemption, while the commercial side, where the underlying economics are strongest, has waited through multiple sessions for a committee vote.

The pattern. New York’s 2022 energy storage roadmap set a target of 6 gigawatts by 2030, one of the larger state storage goals in the country. The state has not stopped taxing the commercial equipment that target implies. The headline commitment stays in place while the granular mechanism that actually moves a building owner’s decision, the tax treatment of the hardware, remains unresolved.

For developers and building owners, the practical effect is uncertainty about a line item they cannot price. A commercial storage proposal written in June 2026 cannot tell a customer whether the equipment will carry sales tax, because the answer depends on a bill in committee, a budget provision whose status is unconfirmed, and a residential precedent that has expired. Tax treatment that changes by session is harder to underwrite than a demand charge that at least follows a published tariff.

The deployment case for commercial storage in New York does not hinge on the exemption. Demand charges and Local Law 97 carry it regardless. But a state pursuing 6 gigawatts of storage by 2030 still taxes the commercial equipment that goal requires, and the bill written to change that has sat in committee, across more than one session, without a floor vote.
