Are There Any Rebates for Insulation? Credits, HOMES, and HEAR

Insulation rebates and tax credits still exist in 2026, but the biggest one is gone. The federal Energy Efficient Home Improvement Credit, which paid back 30% of insulation material costs, ended for anything installed after December 31, 2025.¹ If your insulation went in during 2025 or earlier, you can still claim that credit on your 2025 return. For new work, your options are Inflation Reduction Act rebate programs, the federal Weatherization Assistance Program for low-income households, and incentives from your local utility.

Claiming the Federal Tax Credit for 2025 Installations

The Energy Efficient Home Improvement Credit under Section 25C paid 30% of the cost of qualifying insulation materials and air sealing products, capped at $1,200 per year across all home envelope improvements. The credit was non-refundable, so it could zero out your tax bill but never generate a refund, and any unused portion could not be carried into a later year.²³

The credit covered the insulation products, not the labor to install them. You can claim 30% of what you paid for fiberglass batts, spray foam, rigid boards, blow-in fiber, weather stripping, caulk, or house wrap, but not what the contractor charged to put them in.⁴⁵ The insulation had to be installed in an existing home that you owned and used as your principal residence. Renters, landlords, and second-home owners were excluded.⁶

To claim it, file IRS Form 5695 with your 2025 individual return.⁸ The form calculates the credit from your documented material costs, and that amount reduces what you owe. This is the final year the credit is available, so pull your receipts together before filing.

IRA Rebates: HOMES and HEAR

Two rebate programs from the Inflation Reduction Act run on their own funding and were not touched when the tax credit was repealed. Availability, though, depends on your state.

The Home Efficiency Rebates program (HOMES) pays based on modeled or measured energy savings from a whole-house retrofit. Projects that cut energy use by 20% or more can qualify for up to $2,000, and those hitting 35% or more can qualify for up to $4,000. Both caps double for low- and moderate-income households.⁹ HOMES requires a home assessment before work begins. For the modeled savings path used in most single-family projects, a qualified assessor calculates projected savings, and your rebate is based on that pre-upgrade estimate rather than post-installation measurement.¹⁰

The Home Electrification and Appliance Rebates program (HEAR) targets specific upgrades and caps insulation and air sealing at $1,600 per household.¹¹ HEAR is limited to households earning less than 150% of area median income. Below 80% of AMI, the rebate can cover 100% of project cost within the per-item caps. Between 80% and 150% of AMI, it covers up to 50%. Households above 150% of AMI are not eligible.¹² Where the program is running, the rebate is applied as a discount at the point of sale, so you pay the reduced amount to your contractor. States verify income through tax returns, enrollment in qualifying low-income programs, or in some cases self-attestation.¹⁰

Here’s the practical limit: despite roughly $9 billion in allocated funding, most states have not launched these programs, and the rollout has been slow. Check with your state energy office before planning a project around a HOMES or HEAR rebate.

Free Weatherization for Low-Income Households

If your income qualifies, the federal Weatherization Assistance Program covers insulation and other efficiency upgrades at no cost to you. Run by the Department of Energy since 1976, WAP serves about 32,000 homes per year, and participating households save an average of $372 or more annually on energy bills. The program has helped more than 7.2 million families to date.¹³ Applications go through local weatherization agencies, and your state energy office can point you to the right one.

Utility Company Rebates

With the federal credit ended, utility programs are the most accessible option for many homeowners in 2026. Local utilities often run their own insulation incentives, and the format varies. Some are instant point-of-sale discounts. Others are rebate checks issued after an inspector verifies the work.

Eligibility usually turns on the R-value you install. R-value measures thermal resistance, and higher numbers mean better performance. Your climate zone determines the recommended R-values for attics and walls, and utility programs typically require you to meet or exceed those regional benchmarks.¹⁴ Rebate amounts, income requirements, and deadlines differ by provider. Call your utility before you start work to confirm what’s offered and what paperwork they need.

How These Incentives Interact

Combining incentives requires some care. A public utility subsidy must be subtracted from your qualified expenses before you calculate the federal tax credit. If you spent $2,000 on insulation materials and your utility covered $500, your creditable amount drops to $1,500. This applies whether the utility pays you or your contractor.⁷

Payments from HOMES and HEAR are treated as rebates for federal tax purposes, which means they reduce your purchase price rather than counting as taxable income.¹⁵ State-run incentives are trickier. Many states label their programs as rebates, but those payments may not qualify as rebates under federal tax law, in which case they can count as taxable gross income on your federal return. If you receive a state incentive, consider running the tax treatment past a professional.

Federal rules also prohibit using two federal funding sources on the same single upgrade. A HEAR rebate and the 25C tax credit cannot both apply to the same insulation job. Different federal incentives can cover different components of a larger renovation as long as each source pays for a distinct item.

Documentation to Keep

Organized records are what separates an approved claim from a denied one, whether you’re filing the 25C credit for 2025 work or applying for a rebate.

Manufacturer’s Certification Statement confirming the product meets required performance standards. Every qualifying product should come with one.
Itemized receipts that clearly separate material costs from labor. A single lump-sum invoice creates problems because the federal credit covers materials only.
Product packaging or data sheets showing R-value. Utility programs and energy auditors both look for this.
The exact date installation was finished. For the 25C credit, the insulation had to be placed in service by December 31, 2025.
Income verification for IRA rebates, meaning a recent tax return or documentation of enrollment in a qualifying assistance program.

For the federal credit, this documentation feeds into Form 5695, filed with your tax return. Utility rebates usually go through an online portal or a mailed rebate packet, and most programs set a submission window after installation. Miss the window and you lose the rebate, so confirm the deadline before the project starts.
