Buying a Home Battery in NY? The Equipment and Installation Are Sales-Tax Free Through May 2028
New York exempts qualifying residential energy-storage system equipment and installation from state and local sales and use tax through May 31, 2028.
Who
People purchasing and installing qualifying residential energy-storage systems in New York.
What to do
Start here: Confirm the installer is treating the qualifying battery equipment and installation as sales-tax exempt and keep the contract/invoice showing the exemption.
Eligibility: The equipment and installation must meet New York's residential energy-storage exemption rules during the eligible period.
What you get
Qualifying residential battery-storage equipment and installation are exempt from New York state and local sales/use tax.
Benefit: The state and local sales tax that otherwise would apply to qualifying equipment and installation.
Possible value: Depends on system cost and local sales-tax rate; on a large battery installation the savings can be hundreds or thousands of dollars.
Good to know
Important: The current Tax Department guidance extends the exemption through May 31, 2028. Older state materials may still show the previous May 31, 2026 expiration.
Availability: Active through May 31, 2028
Why people miss it: Home-battery buyers may focus on energy incentives and overlook the separate sales-tax exemption built directly into the purchase price.
