End of Solar Tax Credits: Implications for Future Projects
The Investment Tax Credit (ITC) and Production Tax Credit (PTC) for unstarted solar projects will expire on July 4, 2026, under the One Big Beautiful Bill of 2025. This marks a significant shift, as ongoing projects maintain their tax benefits, while new initiatives face uncertainty in funding and viability.

As of July 4, 2026, the ITC and PTC for new solar projects will cease to exist, impacting future solar energy investments. The ITC began in 1978 under President Carter with a 10% credit, evolving through various extensions and modifications over the decades, notably reaching 30% in 2005 and 2022.
Key legislative changes included the Energy Policy Act of 1992, which initially excluded solar from the PTC, and the Consolidated Appropriations Act of 2016, which established a phase-down of benefits. The recent Inflation Reduction Act restored the ITC to 30% but its future remains uncertain post-2026. The expiration of these credits may lead to reduced investment in solar infrastructure, potentially hindering the sector's growth.
