Increases the amount of geothermal energy systems tax credits

This bill increases tax credits for installing geothermal energy systems. It raises the maximum credit to $10,000 for systems placed in service on or after July 1, 2025 (up from $5,000 before June 2025). It also adds refundability for qualifying low-income taxpayers or those in disadvantaged communities, allowing excess credits to be refunded instead of carried forward starting in 2026. The policy directly affects homeowners and businesses installing geothermal systems, providing greater financial incentives for adoption.
