Federal Residential Solar Tax Credit Concludes for Systems Placed in Service After December 31, 2025
The 30% federal residential solar tax credit, a significant incentive for homeowners installing solar energy systems, has concluded for systems placed in service after December 31, 2025. This tax credit allowed homeowners to offset a portion of their federal tax liability with the cost of their solar installations. The federal solar tax credit is distinct from other solar incentives, such as state incentives, utility rebates, and renewable energy credits (RECs), which operate through separate mechanisms. For individuals purchasing solar systems with cash or a loan in 2026, the listed prices for solar installations will not include this federal tax credit, meaning the full cost will be borne by the homeowner before any state or utility incentives are applied. The tax credit could only be utilized against U.S. federal tax liability, and transfer buyers under Section 6418 were required to be U.S. taxpayers.
