Federal Solar Tax Credit remains available for:
- Commercial
- Nonprofit
- Public-sector solar projects
As of January 1, 2026, the federal solar tax credit is no longer available for new residential solar installations. On the commercial side, the credit is still 30 percent, but new projects now have to be fully operational by December 31, 2027 to claim it.
What Is the Federal Solar Tax Credit?
The federal solar tax credit allows eligible project owners to recover a percentage of their solar installation costs through federal tax incentives.
There were two primary versions of this incentive:
- Residential Clean Energy Credit – for homeowners (now expired)
- Solar Investment Tax Credit (ITC) – for businesses, nonprofits, and public-sector projects (still active)
These tax credits allow you to deduct a percentage of your solar system costs from your federal taxes. Eligible project costs include:
- Solar panels, inverters, and racking
- Labor and installation
- Electrical work and interconnection equipment
- Battery storage systems of 5 kWh or larger
- Permitting, inspections, and even sales tax
For commercial projects, the ITC can cover 30% or more of total system costs when bonus credits are applied.

Commercial Solar Investment Tax Credit (ITC)
The Solar Investment Tax Credit remains active for commercial and institutional solar projects and offers significantly more flexibility than the former residential program.
Who Qualifies
- Businesses of any size
- Nonprofit organizations
- Schools and universities
- Municipalities and local governments
- Tribal entities
- Agricultural and industrial facilities
Base Credit Amount
Commercial projects qualify for a 30 percent base tax credit if either of the following applies:
- The system capacity is under 1 megawatt (MW), or
- The project meets federal prevailing wage and apprenticeship requirements
If a project is 1 MW or larger and does not meet labor standards, the base credit is reduced to 6 percent.
Every project also has to meet the construction start and placed-in-service deadlines covered in the next section. Those deadlines apply regardless of system size or credit rate.
Commercial Bonus Credits (Stackable)
Eligible projects can increase the value of the ITC by stacking bonus credits:
- Domestic Content Bonus (+10%)
Uses U.S.-manufactured solar panels and qualifying components - Energy Community Bonus (+10%)
Project is located in a qualifying fossil-fuel-dependent area or brownfield site - Low-Income Community Bonus (+10–20%)
Available for qualifying projects serving or located in low-income areas through a federal application process
Maximum potential credit
Up to 50 percent for projects earning both the domestic content and energy community bonuses
Equipment Sourcing Requirements
Projects that began construction after December 31, 2025 are subject to federal restrictions on how much of a project’s value can come from prohibited foreign entities, primarily manufacturers with ownership or financing ties to China, Russia, Iran, and North Korea. A minimum share of manufactured product costs has to come from non-restricted sources, and that minimum rises for projects starting in later years.
Failing the threshold disqualifies the credit entirely, no matter how well the project performed on every other requirement. Ask any installer bidding your project how they document supplier sourcing. A vague answer is a real risk to your credit.
Commercial ITC Timeline and Key Deadlines
Unlike the former residential credit, the commercial ITC is governed by both construction start dates and placed-in-service deadlines. One of those dates has already passed, which determines everything about how a project qualifies today.
Key Commercial ITC Dates
July 4, 2026
Begin Construction Deadline (Passed)
Commercial solar projects that had begun construction by this date preserved a longer completion window. This deadline has passed. Projects that did not start construction in time now fall under the December 31, 2027 rule below.
December 31, 2027
Placed-in-Service Deadline for New Projects
This is the deadline that applies to almost every project being planned today. The system must be installed, inspected, interconnected, and granted permission to operate before January 1, 2028. There is no reduced credit for finishing late. After that date, eligibility ends.
2028–2030
Extended Window for Projects Already Under Construction
Projects that began construction on or before July 4, 2026 generally have four calendar years from the year construction started to be placed in service. A project that started in 2026 has until December 31, 2030. This is not automatic. It requires demonstrable continuous progress and the documentation to support it.
Why the Commercial Timeline Matters
- For new projects, the credit now depends entirely on when the system is turned on, not when it is designed or contracted.
- “Placed in service” means the utility has granted permission to operate. Panels on a roof do not count.
- Permitting and interconnection timelines with DTE Energy and Consumers Energy are outside any installer’s control, and both will tighten as the deadline approaches.
Working backward from December 31, 2027, a project that begins its design conversation in late 2026 or the first half of 2027 has a realistic path. One that waits until mid-2027 likely does not, particularly for larger arrays.
Battery Storage Follows a Different Clock
The December 31, 2027 deadline applies to solar. It does not apply to energy storage with solar batteries. Standalone battery storage remains eligible for the 30 percent credit for projects beginning construction through 2033, with a phase down after that. Storage paired with a solar array is subject to the same sourcing rules, but not to solar’s accelerated completion date.
For a facility that cannot realistically finish a full array in time, storage may still have a federal credit path.
Credit Transfer and Direct Pay Options
Recent federal changes have expanded access to the ITC beyond traditional tax-paying businesses:
- Credit Transfer
For-profit businesses may sell their tax credit to another entity for immediate cash value - Direct Pay
Tax-exempt entities such as nonprofits, schools, and municipalities may receive the credit as a direct payment from the IRS, even without tax liability
These options allow organizations that previously could not benefit from tax credits to fully monetize federal solar incentives. Both are tied to the same underlying credit, which means both are subject to the same December 31, 2027 placed-in-service deadline.
How to Claim the Commercial Solar Tax Credit in Michigan
- Install and place the solar system into service
- Maintain detailed invoices and project documentation
- Confirm eligibility for any applicable bonus credits
- File IRS Form 3468 with your federal tax return
- Claim the credit in the tax year the system becomes operational
Tax-exempt organizations using direct pay have an additional step. The IRS requires a pre-filing registration before the return is submitted, and the registration number has to appear on the return itself. This is the step first-time filers miss most often. Because commercial incentives are complex and project-specific, work with a CPA who has handled Section 48E filings recently.
