COMMERCIAL SOLAR TAX CREDIT GUIDE

WHAT BUSINESSES NEED TO KNOW

Act Before Incentives Change — 30% Solar Credit Ends Soon

Commercial energy costs are rising and Federal incentives for commercial solar have never been richer—or more time-sensitive.

Between shifting deadlines, new depreciation rules, and tightening bonus credit windows, the next 18 months are critical for commercial property owners and developers who want to capture the full value of solar incentives.

The 30% Federal Investment Tax Credit (ITC) for commercial solar and battery storage is still available, but 2025 legislation accelerated when that credit phases out for new projects. In practice, most businesses now have a firm window that runs through projects that begin construction by July 4, 2026, or are placed in service by December 31, 2027. After that, many new solar projects may receive a sharply reduced credit—or none at all.

At the same time, restored 100% bonus depreciation and stackable bonus credits can allow many organizations to recover 40–60% or more of project costs through tax benefits in the first year alone.

Brightergy has delivered hundreds of commercial-scale solar projects over more than two decades, with a focus on helping businesses, municipalities, and nonprofits capture every available incentive.
