TL;DR: The federal solar Investment Tax Credit (ITC) covers 30% of the total installed cost of a residential solar system, including panels, batteries, labor, and permits. For a $30,000 system, that is a $9,000 tax credit claimed on IRS Form 5695. The 30% rate holds through 2032 before stepping down.

What the Federal Solar Tax Credit Actually Covers
The federal solar Investment Tax Credit (ITC) is a dollar-for-dollar reduction in federal income tax. It equals 30% of the total installed cost of a qualifying solar energy system. Not a deduction. A credit. That distinction matters because a $9,000 credit wipes $9,000 off a tax bill, while a $9,000 deduction only reduces taxable income by that amount (saving roughly $2,000 to $2,500 depending on the bracket).Qualifying costs include more than just the panels sitting on the roof. The ITC applies to:
- Solar photovoltaic panels
- Battery storage systems (10 kWh minimum capacity as of 2023, and batteries qualify even without solar)
- Inverters, racking, and wiring
- Installation labor
- Permit fees and inspection costs
- Sales tax paid on the system
- Roof reinforcement if structurally required for the solar installation
One cost that does NOT qualify: a full roof replacement. If the roof needs new shingles anyway, only the portion of the work directly related to supporting the solar array counts toward the credit.The system must be installed at a primary or secondary residence in the United States. Rental properties do not qualify for the residential credit (though a separate commercial ITC exists for landlords and businesses).
ITC Rate Schedule: 30% Through 2032, Then the Step-Down Begins
The Inflation Reduction Act of 2022 locked in the 30% residential solar tax credit through the end of 2032. After that, the rate drops on a set schedule.
Federal Solar ITC Rate Schedule (Residential Systems)
| Tax Year | ITC Rate | Notes |
| 2022 – 2032 | 30% | Full rate locked in by the Inflation Reduction Act |
| 2033 | 26% | First step-down year |
| 2034 | 22% | Second step-down year |
| 2035 and beyond | 0% | Residential credit expires unless Congress extends it |
Before the Inflation Reduction Act passed, the credit was set to drop to 22% in 2023 and disappear for residential systems entirely in 2024. Congress reversed that decline and extended the full 30% rate for a decade.
The “placed in service” date determines which year’s rate applies. That means the system must be fully installed, connected, and operational. Signing a contract or making a deposit in 2032 does not lock in the 30% rate if the installation finishes in 2033. Homeowners planning a 2032 installation should build in a timeline buffer, because permitting and utility interconnection delays can push completion dates by weeks or months.
And here is something solar shoppers should factor in: the step-down creates urgency. Installers get busier in the final year of any rate window, which means longer wait times and potentially higher labor costs. Getting quotes 12 to 18 months before a deadline is smart planning.
How to Claim the Solar Tax Credit: IRS Form 5695, Step by Step
Claiming the federal solar tax credit requires filing IRS Form 5695 (Residential Energy Credits) with a federal tax return. The process is straightforward, but getting the numbers right matters.Here is how it works:
- Gather all invoices and receipts from the solar installation, including equipment, labor, permits, and battery storage if applicable
- Add up the total qualifying costs (this is the “cost basis” for the credit)
- Multiply the total by 0.30 to calculate the credit amount
- Enter the amount on IRS Form 5695, Part I, Line 1
- Complete the worksheet on Form 5695 to determine the allowable credit based on tax liability
- Transfer the final credit amount to Schedule 3 (Form 1040), Line 5
The credit reduces federal income tax owed. It does not generate a refund beyond what was already withheld. So a homeowner who owes $7,000 in federal taxes and claims a $9,000 solar credit brings the tax bill to $0 and carries forward the remaining $2,000 to the following year.Most tax software (TurboTax, H&R Block, FreeTaxUSA) includes Form 5695 and walks through the calculation automatically. For a complex installation with batteries, multiple buildings, or a home office, working with a CPA or tax professional is worth the $200 to $400 fee.
Carrying Forward Unused Credit
The solar ITC has no cap on the credit amount. A $60,000 system generates an $18,000 credit. But the credit can only offset taxes owed in a given year. When the credit exceeds the tax liability, the unused portion rolls forward.
Carryforward works like this: the remaining credit applies to the next tax year, and the year after that, for as long as it takes to use it up. The IRS allows carryforward for up to 20 years under current rules, which gives plenty of runway for most homeowners.
A practical example: a retired couple with $35,000 in taxable income owes roughly $3,800 in federal tax. Their $9,000 solar credit wipes out $3,800 in Year 1, leaving $5,200 to carry forward. In Year 2, another $3,800 gets wiped out, leaving $1,400. By Year 3, the full credit has been used.
Some homeowners accelerate credit usage by timing income events. Converting a traditional IRA to a Roth IRA, selling investments with capital gains, or taking a larger distribution from a retirement account can increase the tax bill enough to absorb more of the credit in a single year. Consult a tax advisor before making moves like that.
Leases and PPAs: Who Gets the Credit?
Homeowners who lease a solar system or sign a Power Purchase Agreement (PPA) do not get the federal tax credit. The credit goes to the system owner, and in a lease or PPA arrangement, that owner is the solar company.
This is one of the biggest financial differences between buying and leasing. A purchased system (whether paid in cash or financed with a solar loan) lets the homeowner claim the full 30% ITC. A leased system does not.
Solar companies that lease systems factor the ITC into their pricing. They claim the credit themselves and pass some of that savings to the customer through lower monthly payments. But “some” is the key word. The homeowner never sees the full $9,000 credit value on a $30,000 system. The leasing company keeps its margin.
For homeowners who cannot use the full credit (low tax liability, limited income), a lease or PPA might still make financial sense because of lower upfront cost and zero maintenance responsibility. But anyone with enough tax liability to absorb the credit will save more money by owning the system outright.
Stacking the Federal ITC with NYSERDA and NY State Incentives
New York homeowners can stack the federal solar tax credit with state-level incentives. The federal credit, NYSERDA incentives, and the NY State tax credit all apply to the same installation, and none of them reduce the others.
NY Solar Incentive Stack for Residential Systems (as of March 2026)
| Incentive | Type | Amount | Key Details |
| Federal ITC | Tax credit | 30% of installed cost | Claimed on IRS Form 5695; carryforward allowed |
| NYSERDA NY-Sun | Upfront rebate | ~$0.20/watt | Applied by installer at time of purchase; varies by utility territory |
| NY State Tax Credit | Tax credit | 25% of cost, max $5,000 | Claimed on NY state return; non-refundable |
| NY Sales Tax Exemption | Tax exemption | ~8% saved | Solar equipment exempt from state and local sales tax |
| Property Tax Exemption | Tax exemption | 15 years | Added home value from solar excluded from property tax |
Here is what stacking looks like on a $30,000 system for a Hudson Valley homeowner:
- NYSERDA NY-Sun upfront incentive: approximately $0.20/watt on a 10 kW system = $2,000 off the installed price, bringing the net cost to $28,000
- Federal ITC at 30% of $28,000 = $8,400 (the ITC applies to the cost after the NYSERDA rebate, since the rebate reduces the purchase price)
- NY State solar tax credit: 25% of system cost, capped at $5,000
- NY State sales tax exemption: solar equipment is exempt from the 8% state and local sales tax
- Property tax exemption: the added home value from solar is exempt from property tax increases for 15 years
Total incentive value on a $30,000 system: roughly $15,400 in direct credits and rebates, plus ongoing property and sales tax savings. The effective out-of-pocket cost drops to around $14,600.One detail that trips people up: the NYSERDA NY-Sun incentive is applied as an upfront discount by the installer, so the federal ITC is calculated on the reduced price. The NY State tax credit, by contrast, does not reduce the ITC basis. Tax rules can shift, so double-check with a CPA for the most current treatment.
Example Calculation: $30,000 Solar System in the Hudson Valley
Putting the numbers together for a real-world scenario. A homeowner in Dutchess County installs a 10 kW solar panel system with a 13.5 kWh battery backup.
Example: $30,000 Solar + Battery System in Dutchess County, NY
| Line Item | Amount |
| Gross system cost (10 kW solar + 13.5 kWh battery) | $30,000 |
| NYSERDA NY-Sun rebate (~$0.20/watt) | -$2,000 |
| Net cost after rebate | $28,000 |
| Federal ITC (30% of $28,000) | -$8,400 |
| NY State tax credit (25%, capped at $5,000) | -$5,000 |
| Effective out-of-pocket cost | $14,600 |
| Estimated annual electricity savings | $1,800 – $2,200 |
| Estimated simple payback | 6.5 – 8 years |
That $14,600 out-of-pocket cost generates roughly $1,800 to $2,200 in annual electricity savings for a household using 1,000 kWh per month at Central Hudson’s current rates ($0.18 to $0.22/kWh). Simple payback lands between 6.5 and 8 years, with the system producing free electricity for another 17 to 18 years after that (panels carry 25-year performance warranties).
Solar loans spread the upfront cost over 10 to 25 years at rates between 4.5% and 7.5% as of early 2026. Monthly payments on a $14,600 financed amount run $100 to $160 per month on a 15-year term, which is close to or below the average Central Hudson electric bill. Day one, the homeowner’s net energy cost stays flat or drops.

Frequently Asked Questions
Q: Can I claim the solar tax credit if I already installed panels in a previous year?
A: The credit applies to the year the system was placed in service (fully installed and operational). If the system was installed in 2025, the credit is claimed on the 2025 tax return. You cannot retroactively claim it for a system installed years ago if you did not file for it, but you can file an amended return (Form 1040-X) for up to three years after the original filing deadline.
Q: Does the 30% solar tax credit apply to battery storage added later?
A: Yes. Standalone battery storage with at least 10 kWh of capacity qualifies for the 30% ITC even without a solar panel installation. Batteries added to an existing solar system also qualify. The credit applies to the battery hardware, installation labor, and associated electrical work.
Q: What happens if I sell my house after claiming the solar tax credit?
A: Selling the home does not trigger a recapture of the credit, as long as the system was operational while you owned the property. The new homeowner does not get to claim the credit again on the same system. Solar panels increase home value by an average of 4.1% according to Zillow, and NY’s property tax exemption means that increase does not raise the new owner’s tax bill for 15 years.
Q: Is the federal solar tax credit refundable?
A: No. The residential solar ITC is a non-refundable credit, meaning it can reduce federal tax liability to zero but cannot generate a cash refund beyond taxes already withheld. Any unused credit carries forward to future tax years for up to 20 years.
Q: Can I combine the federal solar tax credit with the NY state solar credit?
A: Yes. The federal ITC and New York’s 25% state solar tax credit (capped at $5,000) stack on top of each other. They also stack with NYSERDA’s NY-Sun upfront rebate and the state sales tax and property tax exemptions. None of these incentives cancel out or reduce the others, though the NYSERDA rebate lowers the cost basis for calculating the federal ITC.
