Congress and Trump End Solar Tax Credit: What Homeowners Need to Know Before Dec 31, 2025

A major shift in U.S. energy policy is here.

With the passage of the One Big Beautiful Bill on July 4, 2025, Congress and President Trump have officially voted to end the 30% federal residential solar tax credit (Section 25D) on December 31, 2025. This update marks a significant and accelerated policy shift—one that every homeowner considering solar should act on immediately

What’s Changed

Previously, the 30% Residential Clean Energy Credit was set to continue through 2032, with a gradual phase-down. That phase-down is now canceled. Instead:

• The credit ends completely after Dec 31, 2025
• There is no safe harbor provision for residential projects
• To qualify, your system must be both purchased and installed by the end of this year

This change leaves just a few months to lock in one of the most impactful homeowner solar incentives in U.S. history.

What This Means for Your Solar Investment

Here’s what’s at stake: 

• System cost:$25,000–$30,000 (typical range)
• 30% federal credit:$7,500–$9,000 in potential tax savings
• Net cost without credit:thousands more out-of-pocket

If your system isn’t fully installed by December 31, 2025, you will not be eligible for the credit. Delaying your project by even a few weeks this fall could mean missing out.

Bonus Savings: Group Buy + Federal Credit Ends This Year

2025 is also the final year homeowners in Central Wisconsin can combine: 

• The federal 30% tax credit, and
• The Grow Solar Central Wisconsin Group Buy discount program

 Stacking these two programs can significantly reduce the cost of your system—potentially bringing your out-of-pocket down by $10,000 or more, depending on system size.

Why You Need to Act Now
Between permitting delays, utility interconnection queues, and installer capacity, time is already tight. As we head into fall, availability will shrink further.

To qualify for the credit, your system must be: 

• Fully purchased
• Fully installed and energized
• Operational by December 31, 2025

We recommend starting the process no later than ASAP to ensure your system is installed before the deadline.

Long-Term Benefits Beyond Tax Credits
While the federal tax credit is ending, solar continues to offer long-term value:

• Lower energy bills from day one
• Protection from rising utility rates
• Increased home value and marketability
• Optional battery storage for energy resilience
• Clean, renewable energy for your household
