Massachusetts Battery-Storage Incentives in 2026: What Actually Saves You Money

On January 1, 2026, the federal residential clean-energy tax credits ended. The 30% solar credit (IRS §25D) and the efficiency credit for heat pumps and weatherization (§25C) are no longer available for systems placed in service on or after that date. This is a hard cutoff with no phase-down or partial credit.

The good news: Massachusetts homeowners still have access to substantial incentives—they're just no longer federal. State net-metering rules, utility rebates, state tax exemptions, and local efficiency programs continue to drive real savings. Because these incentives vary by utility and municipality, the math is now local rather than federal. This guide shows you where the money actually is in 2026.

What Ended on January 1, 2026

The federal residential clean-energy credit under IRS §25D (the 30% solar tax credit) expired for all systems placed in service on or after January 1, 2026.

The federal efficiency credit under IRS §25C (covering heat pumps, insulation, windows, and weatherization) also ended on the same date.

There is no partial credit, no phase-down, and no exception. If your system is installed on or after January 1, 2026, you cannot claim either credit on your federal tax return.

Where Massachusetts Incentives Still Work in 2026

Massachusetts state incentives remain active and often substantial. These include net-metering credits (which let you export excess solar power to the grid and receive credits on your bill), state sales-tax exemptions on solar and battery equipment, and property-tax exemptions for renewable-energy systems in many municipalities.

Utility-level rebates and demand-response programs vary by your electricity provider. Eversource, National Grid, and municipal utilities each offer different incentive structures for batteries, heat pumps, and efficiency upgrades.

Local efficiency programs, often funded by state and utility dollars, may offer direct rebates or financing for weatherization, heat-pump installation, and battery storage. The authoritative, regularly-updated source for all state, utility, and local incentives is DSIRE (Database of State Incentives for Renewables & Efficiency).

Frequently asked

Can I still claim the 30% federal solar credit in 2026?

No. The federal residential clean-energy credit (IRS §25D) ended on January 1, 2026, for all systems placed in service on or after that date. There is no partial credit or phase-down. If your solar system is installed in 2026 or later, you cannot claim the 30% federal tax credit.

Are Massachusetts state and utility incentives still available?

Yes. State net-metering rules, utility rebates, state sales-tax exemptions, and property-tax exemptions for renewable-energy systems continue in 2026 and were not affected by the federal credit expiration. These incentives vary by utility and municipality, so your actual savings depend on your location and provider.
