Inflation Reduction Act Energy Incentives: Complete 2026 Guide

1. What the One Big Beautiful Bill Actually Changed

The One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, rewrote the IRA's residential energy incentive landscape, but not uniformly. The law ended both homeowner tax credits (the solar ITC under 25D and the efficiency credit under 25C) after 2025, while the already-appropriated HOMES and HEAR rebate funds kept flowing through states.

What ended immediately: The Section 25D Residential Clean Energy Credit, the 30% solar tax credit with no dollar cap, terminated for homeowner-owned systems on December 31, 2025. There was no phase-out, no grandfather clause for contracts signed earlier, and no transition period. A system installed January 1, 2026 received zero federal credit. The OBBBA FAQ published by the IRS in August 2025 confirmed this explicitly.

What else ended: Section 25C (energy-efficient home improvements) was also terminated for property placed in service after December 31, 2025. What survived: The HOMES and HEAR rebate programs, funded through the Department of Energy via IRA appropriations, continued distribution through state agencies, since their funds had already been allocated to states and could not easily be clawed back.

2. Section 25C: How It Worked Through 2025 (and Why 2026 Installs Don't Qualify)

Section 25C was an annual credit covering 30% of qualifying costs for a range of home improvement categories, subject to per-category annual caps. The One Big Beautiful Bill Act terminated it for property placed in service after December 31, 2025, the amounts below apply only to 2025-and-earlier installs claimed on those tax returns, not to 2026 projects.

What Section 25C covered (2025 and earlier installs):

3. EV Charger Credit: Ended for Chargers Placed in Service After June 30, 2026

The Alternative Fuel Vehicle Refueling Property Credit (Section 30C) covered 30% of the cost of installing a home EV charger in an eligible census tract, capped at $1,000 for residential installations. Under the One Big Beautiful Bill Act, it expired for units placed in service after June 30, 2026, a charger installed today gets no federal credit.

If your charger was placed in service between January 1 and June 30, 2026 at an eligible address, you can still claim the credit on your 2026 federal return using Form 8911. A Level 2 home charger installation typically cost $800–$2,000 including the equipment and electrical work, generating a $240–$600 credit (capped at $1,000). For chargers installed after June 30, 2026, budget the full cost and look for utility or state charger rebates instead.

The credit applied to the property where the charger was installed (your primary residence) and required it to be placed in service, meaning fully functional, by the cutoff date. Signed contracts or payment deposits alone did not trigger eligibility, so a charger ordered before June 30, 2026 but installed afterward does not qualify.

4. HOMES and HEAR Rebate Programs: $8.8 Billion Still Distributing

Unlike tax credits (which require tax liability to claim), the HOMES and HEAR programs provide direct upfront rebates at the point of purchase or shortly after installation. The money was appropriated by the IRA and allocated to state energy agencies, it cannot be rescinded by subsequent legislation in most cases, which is why these programs are still active even as tax credit provisions changed.

HOMES Program (Home Efficiency Rebates)

HOMES is a whole-house performance program, the rebate amount is tied to how much predicted energy your retrofits will save, not a fixed amount per appliance. According to the U.S. Department of Energy program guidelines:

• Households achieving 20–35% modeled energy savings: up to $2,000 (or 50% of project cost)
• Households achieving 35%+ modeled energy savings: up to $4,000 (or 50% of project cost)
• Low-to-moderate income households (under 80% AMI): doubled amounts, up to $4,000 or $8,000
• Maximum single project: $8,000 for LMI households achieving 35%+ savings

The critical requirement is working with a contractor who is certified in your state's HOMES program and using approved modeling software to document projected savings. The rebate follows the modeled savings, not actual measured savings, which makes it more predictable than a performance-based payment in arrears.

HEAR Program (Home Electrification and Appliances Rebates)

HEAR is income-restricted (households under 150% of area median income) but covers a specific list of electrification upgrades with defined per-item rebate amounts:

• Heat pump HVAC: up to $8,000
• Heat pump water heater: up to $1,750
• Electric stove/range/cooktop: up to $840
• Electric clothes dryer: up to $840
• Weatherization (insulation, air sealing, ventilation): up to $1,600
• Electrical panel upgrade: up to $4,000
• Electric wiring: up to $2,500
• Maximum total per household: $14,000

For households earning 80% or below area median income, the HEAR rebate covers 100% of costs up to those limits. For households at 80–150% AMI, it covers 50% of costs. This distinction matters significantly in practice, an 80% AMI household installing a heat pump at $10,000 could receive the full $8,000 HEAR rebate, reducing net cost to $2,000 (the $2,000 Section 25C credit that once covered the rest ended for 2026 installs).

5. State Energy Rebate Programs: Layering on Top

Separate from the federal IRA programs, many states run their own energy efficiency rebate programs, and they can be stacked with federal credits and rebates. The most aggressive state programs easily match or exceed federal incentives in dollar terms.

Sources: State energy office websites, DOE HEAR program tracker. Amounts current as of April 2026; verify current funding availability before assuming rebates are open.

Utility companies, independent of state programs, also run heat pump and efficiency rebate programs that typically don't conflict with any of the above. National Grid, Eversource, Pacific Gas & Electric, and Xcel Energy have each offered $500–$2,500 in heat pump equipment rebates through 2026. Your utility's website or the ENERGY STAR rebate finder will show what's available based on your zip code.

6. How to Stack Incentives: A Real-World Example

Let's model a homeowner in Massachusetts, a 58% AMI household, replacing a gas furnace with a cold-climate heat pump at a total installed cost of $12,000. Here's every incentive layer they can access:

This scenario, an 83% subsidized heat pump installation, is not a hypothetical edge case. It's achievable for lower-income households in states with both active HEAR programs and aggressive state rebate programs, even without the expired 25C credit.

For households not meeting HEAR income thresholds (above 150% AMI), the stack looks different: no HEAR rebate and no 2026 Section 25C credit, but state rebates ($2,000–$10,000 depending on state) plus utility rebates ($500–$2,500) can still reduce a $12,000 project by $2,500–$12,000.

8. Strategic Order of Operations for 2026 Home Upgrades

Given the varying expiration dates and income requirements, the optimal sequence for a homeowner planning upgrades in 2026 is:

1. Get a home energy audit first (no 25C audit credit for 2026). The audit identifies your biggest energy losses and determines which HOMES program savings tier you can realistically reach. It also satisfies the documentation requirement if you pursue HOMES rebates. Many states offer subsidized or free audits for HEAR-eligible households.
2. Claim a 2026 EV charger credit only if the charger was placed in service by June 30, 2026. The Section 30C deadline has passed, chargers installed after June 30, 2026 get no federal credit, so check utility charger rebates instead. If yours was placed in service January 1–June 30, 2026 at an eligible address, file Form 8911 with your 2026 return.
3. Apply to your state's HEAR program before funds exhaust. California ran out of funds in February 2026. Other states will follow. HEAR has the highest potential value ($14,000) and is first-come, first-served in most states.
4. Time the heat pump around rebate availability, not 25C. The $2,000 Section 25C heat pump credit ended for equipment placed in service after December 31, 2025, so 2026 timing should follow state, utility, and HEAR funding windows instead.
5. Phase remaining improvements across subsequent years. If you have more efficiency upgrades planned, sequence them around state and utility rebate program years, Section 25C no longer provides annual caps for 2026 or later work.
