Federal Solar Tax Credit Expired on Dec. 31, 2025.

Important Update: Federal Tax Credit for Solatube Products Ended December 31st 2005. Please note: The federal tax credit for Solatube tubular skylights (with integrated solar-powered NightLight), and solar attic fans expired on December 31, 2025, making this incentive no longer available for new installations.

What Homeowners Need to Know

  • The 30% federal tax credit for qualifying Solatube daylighting and solar ventilation products is no longer available.
  • The program officially ended on December 31, 2025, and there are currently no plans for renewal or extension.
  • Installations completed after the deadline are not eligible for the tax credit. Only projects installed and operational by December 31, 2025, can be claimed.


If your system was installed on or before December 31, 2025, you may still be eligible to claim the credit on your 2025 tax return if you have not already done so. Be sure to consult your tax professional for guidance on claiming your credit and required documentation.
