The 30% Solar ITC Is Still Available in 2026
The federal solar Investment Tax Credit (ITC) provides a dollar-for-dollar reduction of your federal income tax equal to 30% of the total installed cost of a qualifying solar energy system. Established by the Energy Policy Act of 2005 and most recently extended through the Inflation Reduction Act (IRA) of 2022, the ITC remains the single most valuable incentive for residential solar installations in the United States.
For a typical $24,000 residential system in 2026, the ITC provides a $7,200 tax credit — reducing your effective cost to $16,800 before any state or local incentives apply.
ITC Schedule: Current and Future Rates
| Installation Year | Credit Rate | Credit on $24,000 System |
|---|---|---|
| 2022–2032 | 30% | $7,200 |
| 2033 | 26% | $6,240 |
| 2034 | 22% | $5,280 |
| 2035 onward | 0% (unless extended) | $0 |
The 30% rate is locked in through December 31, 2032. Systems must be placed in service (operational and connected) by that date — not merely contracted or purchased. Planning your installation timeline is critical as the deadline approaches.
Eligible Expenses
The ITC covers the complete installed cost of your solar energy system, including:
- Solar panels and modules — all photovoltaic hardware
- Inverters — string inverters, microinverters, or DC optimizers
- Battery storage systems — must have capacity of 3 kWh or greater (standalone batteries also qualify since 2023)
- Mounting and racking hardware
- Wiring, conduit, and electrical components
- Installation labor costs
- Permit fees and inspection costs
- Engineering and design fees
- Sales tax on all qualifying components
Who Qualifies?
Homeowners
You must own the solar system (purchased outright or financed with a loan) and it must be installed on your primary or secondary residence in the United States. The home can be a house, condo, co-op, houseboat, mobile home, or manufactured home. The system must be new — used equipment does not qualify.
Who Does NOT Qualify
- Renters — you must own the property (or a property you occupy as a residence)
- Leased or PPA systems — the ITC goes to the system owner (the leasing company), not the homeowner
- Landlords for rental-only properties (use the commercial ITC instead)
How to Claim: Step-by-Step for 2026 Tax Filing
Filing for the ITC is straightforward and does not require itemizing deductions:
- Step 1: Collect your solar installer's final invoice showing total system cost
- Step 2: Complete IRS Form 5695 (Residential Energy Credits), Part I
- Step 3: Enter total eligible costs on Line 1 and calculate 30% on Line 6b
- Step 4: Transfer the credit amount to Schedule 3, Line 5 of your Form 1040
- Step 5: File your return — the credit reduces your tax owed dollar-for-dollar
Carryforward: What If Your Credit Exceeds Your Tax Bill?
The ITC is nonrefundable — it can reduce your federal tax liability to zero but will not generate a refund. If the credit exceeds your tax bill, the unused portion carries forward to subsequent tax years until fully used.
Example: Your ITC is $7,200 but your 2026 federal tax liability is only $5,000. You claim $5,000 in 2026 (zeroing out your tax) and carry $2,200 forward to 2027. There is no expiration on the carryforward under current IRS guidance.
Stacking with State Incentives
Many states offer additional credits and rebates that stack with the federal ITC. Check your state incentive page for details. Be aware that some state credits may reduce the federal ITC basis — consult a tax professional when combining multiple incentives.
Act Before the Step-Down
With the 30% rate guaranteed through 2032, there is still time — but the step-down to 26% in 2033 and 22% in 2034 means delaying costs real money. On a $24,000 system, waiting until 2033 costs you $960 in lost credit. Use our savings calculator to model the impact of timing on your total solar investment.
