Spray Foam Tax Credits and Rebates in PA (2026)

The federal spray foam tax credit: what changed

From January 1, 2023 through December 31, 2025, the Energy Efficient Home Improvement Credit (section 25C of the tax code) let homeowners take 30% of the cost of qualifying insulation and air-sealing materials off their federal taxes. Insulation counted toward an overall limit of $1,200 a year. Labor for insulation didn't count, only the materials.

The 2025 budget law, Public Law 119-21 (the "One Big Beautiful Bill Act"), signed July 4, 2025, cut it off. The IRS puts it plainly: "The credit will not be allowed for any property placed in service after December 31, 2025."

The test is when the work is placed in service, so spray foam installed in 2026 doesn't qualify. The IRS's question-and-answer page on the change doesn't address a deposit paid in 2025 for work finished in 2026. If that's you, ask a tax professional.

If your insulation went in during 2025

The credit is claimed on IRS Form 5695 with your 2025 return. If you already filed and missed it, ask a tax preparer whether an amended return makes sense. We can't give tax advice, but we can tell you what helps: an itemized invoice that shows the insulation materials separately from labor.

Watch for old ads

Plenty of contractor websites and ads still promise "30% back" on insulation. For work done in 2026, that federal credit no longer exists.

45L: the builder credit

Builders could claim 45L for qualified new energy-efficient homes. Under the same 2025 law, it doesn't apply to any home acquired after June 30, 2026. A builder with homes that closed before that date should talk to their tax advisor about whether those still qualify.

Pennsylvania's IRA home energy rebates

Pennsylvania's share of the federal Home Energy Rebates is run by the Department of Environmental Protection (DEP) under the name Penn Energy Savers. It combines two programs: HOMES, based on whole-home energy savings, and HEEHR, the High-Efficiency Electric Home Rebate (often called HEAR).

Status: DEP says the U.S. Department of Energy released new guidance on June 1, 2026, and that as of September 2026, DEP is awaiting final DOE approval to launch. Homeowners can't apply yet.

Federal law sets the electrification rebate limits:

The total cap per household across all items is $14,000. Pennsylvania's program sets the final rules, including contractor requirements and how rebates are paid. You can sign up for launch updates at pennenergysavers.com. Don't sign a contract that depends on a rebate that hasn't launched.

Utility programs

Pennsylvania's large electric utilities run efficiency programs under Act 129, in multi-year phases. Phase V began June 1, 2026, and the approved plans shifted low-income program money toward deeper measures such as insulation. Gas utilities run income-qualified weatherization, mostly through the PUC-required Low Income Usage Reduction Program (LIURP). The LIHEAP Clearinghouse reports that the state's 15 major gas and electric utilities participate in LIURP.

One detail matters if you heat with gas: FirstEnergy's Phase IV rebate tiers were based on kilowatt-hours saved, from 250 kWh up to more than 3,000 kWh. A home heated with gas saves mostly gas, so it may qualify for a small electric rebate or none.

Weatherization Assistance Program

The federal Weatherization Assistance Program is run in Pennsylvania through the Department of Community and Economic Development (DCED) and local agencies. It's for households at or below 200% of the federal poverty level, with priority for older residents, people with disabilities, families with children and high energy users.

Each home gets an energy audit. Work can include air sealing guided by a blower door test, insulation and ventilation in attics, walls, basements and crawlspaces, heating system repair or replacement, and the health and safety repairs needed to do that work. DCED lists the average spending per household at $8,547. You apply through the weatherization agency that serves your county.

Before you buy: confirm the program

1. Check that the program is open today, on its own website, not in a contractor's ad.
2. Ask whether an audit or pre-approval is required before work starts. FirstEnergy's Phase IV rebate required the audit first and installation within 120 days of it.
3. Ask whether you must use a participating contractor.
4. Get the product, thickness, and before-and-after R-values on the invoice. Programs often ask for them.
5. Keep every invoice, with materials listed separately from labor.
6. Don't count a rebate in your budget until it's approved in writing.
