Federal Tax Incentives
The Solar Investment Tax Credit (ITC) Explained
The federal ITC is one of the most powerful financial incentives available to solar contractors and their clients. Understanding how to qualify — and document it correctly — is critical to capturing its full value.
What Is the Federal ITC?
The Investment Tax Credit (ITC), established under Section 48 of the Internal Revenue Code, allows businesses and homeowners to deduct a percentage of their solar installation costs directly from their federal taxes. For projects placed in service in 2024 and beyond, the credit stands at 30% under the Inflation Reduction Act — with bonus adders available for projects meeting additional criteria.

Who Is Eligible?
The ITC applies to a broad range of solar installations, but eligibility depends on several key factors. We assess every project against current IRS guidance to confirm qualification before you commit resources.
Residential Solar Systems
Homeowners who own (not lease) a solar PV system installed on their primary or secondary U.S. residence may claim the ITC against their personal income tax liability.
Commercial & Industrial Projects
Businesses that own solar systems installed on commercial properties — including offices, warehouses, and manufacturing facilities — can claim the ITC against their corporate tax liability.
Community Solar Projects
Subscribers to qualifying community solar projects may be eligible for the ITC, subject to specific ownership and subscription structure requirements.
Battery Storage Systems
Standalone battery storage systems (100% charged from solar) placed in service after December 31, 2022 are now eligible for the ITC under the Inflation Reduction Act.
Bonus Credit Adders
The Inflation Reduction Act introduced bonus adders that can increase the effective ITC rate beyond 30% for projects meeting additional criteria.
Energy Community Bonus
Projects located in energy communities — areas historically dependent on fossil fuel industries or with high unemployment — qualify for an additional 10% credit.
Domestic Content Bonus
Projects using steel, iron, and manufactured products produced in the United States may qualify for an additional 10% credit adder.
Low-Income Community Bonus
Projects located in low-income communities or on Indian land, or that serve low-income residential buildings, may qualify for a 10–20% bonus adder.
Apprenticeship & Prevailing Wage Requirements
Under the Inflation Reduction Act, solar projects that meet prevailing wage and apprenticeship (PWA) requirements qualify for the full 30% ITC rate. Projects that do not meet these standards are subject to a significantly reduced base credit of just 6%. For most contractors, PWA compliance is not optional — it is the difference between a meaningful credit and a minimal one.
Key Thresholds
Prevailing Wage
All laborers and mechanics employed on the project must be paid wages at rates not less than the prevailing rates for the applicable locality, as determined by the Department of Labor under the Davis-Bacon Act.
Apprentice Hours
A minimum percentage of total labor hours must be performed by qualified apprentices from registered apprenticeship programs. The threshold is 15% for projects beginning construction in 2023 and beyond.
Apprentice-to-Journeyworker Ratio
Contractors must comply with the ratio of apprentices to journeyworkers established by the applicable registered apprenticeship program, and must request apprentices from a registered program in good faith.
How We Help You Stay Compliant
Apprentice Hour Tracking
We implement systems to track and document apprentice labor hours across your projects, ensuring you meet the required percentage thresholds and can demonstrate compliance to the IRS.

We assist with certified payroll recordkeeping to document prevailing wage compliance — a requirement for substantiating the full ITC rate in the event of an audit.

We help contractors establish relationships with registered apprenticeship programs and document good-faith requests for apprentices, protecting your credit claim even when apprentices are unavailable.

We organize and maintain all PWA compliance records — payroll data, apprentice certifications, program correspondence — so you are prepared if the IRS requests substantiation.
