The US federal Investment Tax Credit (ITC) is one of the most valuable financial incentives available to homeowners adding solar battery storage. In 2026, it covers 30% of the total installed cost of a qualifying battery system — meaning a $12,000 battery installation could reduce your federal tax bill by $3,600.
But the ITC has rules, limits, and nuances that can trip up homeowners who don't understand how it works. This guide explains everything you need to know to claim the full credit you're entitled to.
What Is the Investment Tax Credit?
The Investment Tax Credit is a federal income tax credit that reduces the amount of federal income tax you owe, dollar for dollar. It's not a rebate (you don't get a cheque), and it's not a deduction (which only reduces your taxable income). It's a direct reduction in your tax bill.
Example:
- Battery installation cost: $12,000
- 30% ITC: $3,600
- Your federal tax bill before ITC: $8,000
- Your federal tax bill after ITC: $4,400
You save $3,600 in real money — as long as you owe at least $3,600 in federal income tax that year.
The ITC was extended and expanded by the Inflation Reduction Act (IRA) of 2022, which locked in the 30% rate through 2032. After 2032, the rate is scheduled to step down to 26% in 2033 and 22% in 2034, before expiring for residential installations in 2035 (unless Congress extends it again).
