The Federal Residential Credit Ended for New 2026 Installations
The federal Residential Clean Energy Credit under Section 25D ended for installations completed after December 31, 2025. Public Law 119-21, signed July 4, 2025, terminated the credit for expenditures after that cutoff. Do not include this homeowner credit as an available benefit in a proposal for a new installation completed in 2026.Source: IRS: credit termination FAQs · IRS: Residential Clean Energy Credit
Under Section 25D(e)(8)(A), an expenditure is treated as made when installation is completed. Paying a deposit in 2025 does not preserve the credit for a system completed in 2026. An unused credit from a qualifying 2025 installation may generally be carried forward; ask a qualified tax professional to review your installation records and tax circumstances.Source: IRS: credit termination FAQs · IRS: Residential Clean Energy Credit
Connecticut RRES: Start With United Illuminating
Residential Renewable Energy Solutions (RRES) launched in January 2022. PURA describes it as a six-year program replacing legacy net metering and the residential solar incentive program (RSIP). Eversource Energy and The United Illuminating Company (UI) administer it. Bridgeport homeowners go through UI for electric distribution and RRES.Source: PURA: RRES overview · UI: RRES program manual (2026)
RRES offers two tariff options: Buy-All and Netting. These are utility compensation arrangements, separate from the federal residential tax credit. Use the current UI program manual when reviewing an application, and ask the installer to identify the selected tariff and who receives any payments or credits.Source: PURA: RRES overview · UI: RRES program manual (2026)
Property-Tax Exemption: File by November 1
CGS 12-81(57)(A)(i) provides an exemption for qualifying Class I renewable energy sources, including solar, installed for private residential electricity use or on a farm on or after October 1, 2007. Estimated annual production must not exceed the location’s estimated annual load. Eligible property types are single-family homes, two-to-four-unit multifamily dwellings, and farms.Source: CT OLR: solar property-tax exemptions
Claim the exemption using Form M-44 / M-44a with the Bridgeport assessor on or before November 1. Confirm the applicable form, supporting records, and assessment year before filing. If the system is leased or owned by a third party, ask the assessor whether the specific installation qualifies and who should apply; do not assume eligibility from an installer’s proposal.Source: Bridgeport: Form M-44 / M-44a
The ordinance-based exemption in CGS 12-81(56) concerns solar heating and cooling systems. It is separate from the residential solar-electric exemption above. Make sure advice and paperwork refer to the type of equipment actually being installed.Source: CT OLR: solar property-tax exemptions
Connecticut Sales and Use Tax
CGS 12-412(117)(A) exempts sales and use of solar energy electricity generating systems, related equipment, and services for installing those systems. Ask the installer to show how the exemption is applied to eligible items on your proposal and invoice. Confirm the treatment of unrelated roof or electrical work separately.Source: CGS 12-412(117)(A): sales and use tax
Batteries: Review Energy Storage Solutions Separately
Energy Storage Solutions is overseen by PURA and administered by the Connecticut Green Bank, Eversource, and UI. Its April 1, 2026 restructuring shifted the emphasis toward performance over time and away from upfront support. The new structure applies to enrollment applications submitted on or after that date.Source: Energy Storage Solutions: April 2026 changes
Before adding storage, ask an eligible contractor to explain participation requirements, how battery use affects performance incentives, and how the proposal addresses your backup priorities. Review the current program materials alongside the battery contract.Source: Energy Storage Solutions: April 2026 changes
Compare Tariffs and Ownership Carefully
Buy-All
The system exports all electricity it produces to the grid without first supplying the home. You continue purchasing the electricity your home needs from UI. Ask how on-bill compensation and any designated payment beneficiary are recorded in the application.Source: UI: tariff options · UI: RRES program manual (2026)
Netting
The system supplies the home first and exports excess electricity. Under UI’s description, energy not consumed within the month is netted, with credits applied to the bill. Review the tariff’s credit treatment with UI before relying on bill projections.Source: UI: tariff options · UI: RRES program manual (2026)
Purchased systems and loans
Do not build a cash purchase or loan repayment plan around a new Section 25D credit for a 2026 completion. Ask for a proposal that identifies each Connecticut exemption and utility assumption separately.Source: IRS: credit termination FAQs
Leased solar equipment
Public Law 119-21 amended Section 48E to deny the credit for specified residential solar property rented or leased to a third party. A solar lease is not a safe example of a surviving federal benefit.Source: Congress: Public Law 119-21 · IRS: Form 3468 instructions
Power purchase agreements
A power purchase agreement (PPA) is legally different from a lease, but that difference does not establish federal credit eligibility. Treatment is contract-specific. Request the precise legal basis for any claim and independent tax advice before relying on it.Source: Congress: Public Law 119-21 · IRS: Form 3468 instructions
Keep the Evidence Behind Your Proposal
Keep the signed contract, invoices, proof of completion, equipment information, utility approvals, and exemption filings together. Ask who is responsible for each submission. For an unused credit from a qualifying 2025 installation, have your tax professional check carryforward records.Source: IRS: Residential Clean Energy Credit

How do I claim the solar property-tax exemption?
