IMPORTANT INFO ON FED TAX CREDIT: The 30% federal Residential Clean Energy Credit for homeowners (IRS Section 25D) has ended. Under the July 2025 federal tax law (Public Law 119-21), the credit is not allowed for expenditures made after December 31, 2025, and the IRS treats an expenditure as made when installation is completed. Home solar, wind, geothermal and battery storage systems installed in 2026 or later do not qualify, even if they were paid for in 2025. Business and commercial solar and wind credits (Sections 48E/45Y) were also cut back under the same law and now carry strict construction and placed-in-service deadlines.
Installed a qualifying system on or before December 31, 2025? The credit is claimed on IRS Form 5695 for the tax year the installation was completed, and any unused credit can be carried forward to future tax years. Please talk with a tax professional about your situation.
