Solar Investment Tax Credit (ITC)

A federal tax credit that reduces the cost of installing a solar energy system by a percentage of eligible costs for residential and commercial properties.

The Solar Investment Tax Credit, or ITC, is a federal tax credit that reduces the cost of installing a solar energy system by a percentage of eligible costs. In 2026 it remains a major incentive for homeowners and businesses, with rules that can change over time. Always verify current IRS guidance.

What is the Solar Investment Tax Credit ITC and who can use it?

According to Solar Panel FAQ, the ITC is a federal program that offsets part of the cost of a solar energy system. It applies to new solar installations placed in service in the United States and is available to eligible property owners, including homeowners and businesses. The ITC is a credit, not a deduction, meaning it reduces your tax liability dollar-for-dollar. For example, if your system costs $20,000 and you qualify for a 30 percent credit, you could reduce your tax bill by up to $6,000, depending on your tax situation. The ITC has helped millions start solar by lowering upfront costs, and it remains one of the strongest incentives for solar adoption. Rules can change over time, so verify current guidance with the IRS.

How ITC is calculated and the most common application scenario

The ITC is calculated as a percentage of eligible costs associated with installing a solar energy system. Eligible costs typically include the solar panels, inverters, mounting hardware, wiring, and installation labor. Land, permit fees, and non solar energy systems generally do not qualify. The credit is applied to your federal tax liability. If your tax bill is smaller than the credit, you typically cannot receive the excess as a refund in that year. The credit can be claimed for both new residential and commercial projects placed in service within the eligible timeframe. For 2026, the credit percentage remains substantial, but it’s important to confirm the current rate each year because policy dates can shift.

Eligibility and who can claim ITC for residential and commercial projects

The ITC is available to property owners who install a solar energy system on their primary residence or a secondary residence, as well as commercial properties and public facilities. If you lease the system or sign a power purchase agreement, the system owner typically claims the ITC, though some contracts may allow passing benefits to the tenant or purchaser. To qualify, the installation must be a new solar energy system and placed in service in the United States. Always review your contract terms and ensure the installation meets IRS standards for ITC eligibility.

How to claim the ITC on your tax return step by step

Claiming the ITC requires filing IRS Form 5695 with your federal tax return. The form guides you through calculating eligible costs and the credit amount. The ITC reduces your overall tax liability and is claimed in the year the system is placed in service. Keep receipts and project invoices for your records, and consult a tax professional if your situation includes complex ownership or financing arrangements. Remember that rules and forms can change, so verify current IRS guidance.

Leasing, financing and ownership structures

If you do not own the solar system, you are typically not eligible to claim the ITC yourself. In most cases, the system owner or the entity that purchases the system claims the ITC. Some arrangements may allow the benefits to pass through to the occupant or tenant, depending on contract terms and local incentives. Homeowners should review financing options and contract language to ensure they maximize available ITCs while aligning with long-term energy goals.

Stacking ITC with state, utility, and local incentives

The ITC can usually be combined with other incentives, such as state tax credits, rebates, and utility-sponsored programs. The total value of incentives varies by state and program, and some incentives may have separate requirements or caps. Planning ahead and coordinating with a solar installer and tax advisor helps you optimize the total incentives available to your project.

Real world examples and what to expect financially

Consider a hypothetical $20,000 solar installation. At a 30 percent ITC, the federal credit would be worth $6,000, reducing the upfront net cost to $14,000 before any additional state or utility incentives. The actual savings depend on your tax situation, energy usage, and the available local programs. Keep in mind that incentives can change over time, so current guidance is essential.

Common myths and misperceptions about ITC

Myth: ITC applies to other energy upgrades. Reality: ITC specifically covers solar energy systems, though other credits may exist for different technologies. Myth: ITC pays the full project cost. Reality: ITC is a credit, not a grant, and it reduces tax liability, not upfront cash. Myth: ITC is guaranteed for every year. Reality: ITC rules evolve, so stay updated with IRS guidance to avoid surprises.
