Battery Tax Credit Calculator 2026
Check whether a quote is still subtracting the old 30% residential federal credit, and force state, utility, and VPP claims into writing.
2026 incentive reality check
Is the quote using a stale tax credit?
This checks the claim pattern, not your tax return. Use it to spot stale federal-credit language and to force state/utility incentives into writing.
Important 2026 federal-credit note
IRS guidance now says the Residential Clean Energy Credit is not available for property placed in service after December 31, 2025. If a 2026 homeowner-owned cash or loan quote still subtracts a 30% residential federal credit, ask the installer to put the claim source in writing before you compare net prices.
State and utility programs can still matter. California buyers should check SGIP, New England buyers should check ConnectedSolutions, Connecticut buyers should check Energy Storage Solutions, and Texas buyers should check VPP terms.
