Window Rebates and Tax Credits Every California Homeowner Should Know (2025)

Updated July 29, 2026

Replacing old windows can improve comfort, appearance, operation, and energy performance. However, homeowners should not assume that every energy-efficient window qualifies for a rebate or tax credit.

In 2026, there is no general federal tax credit for replacement windows placed in service after December 31, 2025. California also does not currently offer a standalone window rebate available to every homeowner.

Some households may still qualify for assistance through local utility programs, income-qualified weatherization programs, or future whole-home energy rebate programs. Eligibility depends on the property, household income, location, energy assessment, and available program funding.

Did the Federal Window Tax Credit End?

Yes. The Energy Efficient Home Improvement Credit previously allowed eligible homeowners to claim 30% of qualifying window costs, up to a total window and skylight credit of $600.

To qualify during 2025, exterior windows and skylights generally had to meet ENERGY STAR Most Efficient requirements. Installation labor did not qualify as part of the window credit.

The credit is not available for windows placed in service after December 31, 2025.

Homeowners who completed a qualifying project during 2025 may still be able to claim the credit on the applicable tax return. Keep your receipts, manufacturer information, product certification documents, and other relevant records. Consult the IRS instructions or a qualified tax professional to determine eligibility.

Are Statewide Window Rebates Available in California?

California is developing and administering several residential energy programs, but they should not be confused with a statewide rebate for purchasing replacement windows.

The California HEEHRA Phase I program currently provides income-qualified rebates for qualifying heat-pump HVAC projects. It is not a standalone replacement-window rebate.

California’s Home Efficiency Rebates program, commonly called HOMES, is intended to support whole-home projects that produce measurable energy savings. Windows could potentially form part of a qualifying whole-home project, but the California Energy Commission currently states that HOMES rebates are not yet available.

This means homeowners should not purchase windows based on an assumption that a future HOMES rebate will reimburse the cost.

What Does the Department of Energy’s Home Upgrades Page Mean?

The U.S. Department of Energy says windows may be included in a Home Owner Managing Energy Savings, or HOMES, project offering rebates of up to $8,000.

That does not mean a homeowner will receive an $8,000 rebate simply for purchasing replacement windows.

HOMES is a whole-home performance program. The potential rebate depends on factors such as household income, the participating state’s program rules, and the amount of modeled or measured energy savings produced by the complete project.

California’s official program page currently says its HOMES rebates are not yet available. Homeowners should rely on the California Energy Commission for the current status of California applications.

The Department of Energy page also contains older federal tax-credit language. For current federal tax eligibility, the IRS should be treated as the controlling source. The IRS confirms that the Energy Efficient Home Improvement Credit does not apply to property placed in service after December 31, 2025.

Are Window Programs Available Through SDG&E?

Some income-qualified SDG&E customers may be eligible for window upgrades through the Energy Savings Assistance Whole Home Pilot.

The pilot is limited to a small number of qualifying customers and considers household income, ZIP code, and expected energy savings. Eligible upgrades may include double-pane windows, insulation, heating and cooling equipment, appliances, and other energy-efficiency measures.

The program covers approved equipment and installation, but customers must complete the qualification and home-assessment process. Window replacement is not automatically available to every SDG&E customer.

Are Low-Income Weatherization Programs Available?

California offers energy-efficiency and weatherization assistance through the Department of Community Services and Development and local service providers.

Qualifying low-income homeowners and renters may receive no-cost energy-efficiency improvements based on household eligibility, property conditions, available funding, and the results of an assessment.

The improvements provided vary by program and property. A household should not assume that complete window replacement will be included. Contact the local service provider before purchasing products or beginning work.ly to your situation.
