The solar industry is facing a significant policy shift that could impact homeowners and businesses considering solar installations. The "One Big Beautiful Bill Act," recently passed by the U.S. House of Representatives, proposes to eliminate the 30% federal solar tax credit for residential systems after December 31, 2025. This change accelerates the phase-out of incentives initially extended through 2032 under the Inflation Reduction Act.
Understanding the Proposed Changes
The federal solar tax credit, also known as the Investment Tax Credit (ITC), currently allows homeowners to deduct 30% of the cost of installing a solar energy system from their federal taxes. Under the proposed legislation, this credit would be eliminated for residential systems placed in service after December 31, 2025. Additionally, the bill introduces stricter deadlines and limitations for commercial and utility-scale projects, including a 60-day window post-enactment to begin construction to remain eligible for certain credits.
Implications for Massachusetts and New Hampshire Residents
For homeowners in Massachusetts and New Hampshire, this proposed change means that the financial benefits of going solar could diminish significantly after 2025. While state-level incentives remain in place, the loss of the federal credit would increase the overall cost of solar installations.
Massachusetts Incentives:
- 15% state tax credit (up to $1,000) for solar installations.
- 100% property tax exemption for 20 years on the added value from solar installations.
- Net metering policies that allow homeowners to earn credits for excess energy produced.
New Hampshire Incentives:
- $200 per kW rebate (up to $1,000) for residential solar systems.
- Absence of state sales tax, reducing the overall cost of solar installations.
- Net metering policies that allow homeowners to earn credits for excess energy produced.
Why Act Now?
Given the proposed elimination of the federal tax credit after 2025, homeowners considering solar installations should act promptly to maximize their savings. To qualify for the current 30% federal tax credit, systems must be installed and placed in service by December 31, 2025. Delays in decision-making could result in higher costs and missed opportunities for savings.
