2026 Energy Rebate Deadlines and Expiration Dates

Energy rebates and tax credits do not last forever. Some programs have firm expiration dates written into law, while others will simply run out of money on a first-come, first-served basis. Knowing the timeline for each program helps you prioritize which upgrades to make now and which can wait. This guide covers every major federal program's deadline, the step-down schedule for solar credits, and the urgency factors you need to understand for 2026.

Federal Program Timeline at a Glance

Section 25C: Energy Efficient Home Improvement Credit

Timeline

The 25C credit was available for improvements placed in service from January 1, 2023 through December 31, 2025; the One Big Beautiful Bill Act ended it early (it was scheduled through 2032). The credit reset every tax year, so homeowners could claim up to $3,200 in credits each year for qualifying improvements. This annual reset is a powerful planning tool.

What This Means for 2026

Improvements placed in service in 2026 do not qualify for 25C. If you completed qualifying work in 2023, 2024 or 2025 and did not claim it, you can still claim it for that tax year (by amended return if needed). For 2026 projects, use HEAR, HOMES, state and utility rebates.

Section 25D: Residential Clean Energy Credit

Timeline and Step-Down Schedule

What This Means for 2026

For solar panel and battery storage installations completed by December 31, 2025, the full 30% credit applied; 2026 installations do not qualify. There is no urgency to rush from a credit-rate perspective. However, solar panel prices and installation costs may change over time, and some state incentives (like SRECs and utility rebates) have their own deadlines. See our solar vs battery comparison for current pricing.

The 25D credit had no dollar cap, but it ended for expenditures made after December 31, 2025, so 2026 installations do not qualify. Unused credit can be carried forward to future tax years if your tax liability is insufficient in the installation year.

HOMES Rebates: The Funding Clock Is Ticking

How Funding Works

Congress allocated approximately $4.3 billion for the HOMES program across all states. Each state received a formula-based allocation and is responsible for designing and administering its own program. Unlike tax credits, which are available to anyone who qualifies, HOMES rebates draw from a limited pool of money. Once a state's allocation is committed, the program closes in that state.

2026 Status

Most states launched their HOMES programs in 2024 or 2025. As of early 2026, many states still have available funds, but some are reporting significant uptake. States with smaller allocations or high demand (particularly those with aggressive marketing and simple application processes) may exhaust funds by late 2026 or 2027. There is no federal mechanism to replenish state allocations once they are spent.

Action Items

• Check your state's HOMES program status through your state rebate page
• If planning a whole-home efficiency project, apply for HOMES sooner rather than later
• Get an energy audit now, even if you are not ready to start construction immediately, as having an audit on file can speed the application process

HEAR Rebates: The Most Time-Sensitive Program

Why HEAR Has the Highest Urgency

The HEAR program received approximately $4.5 billion in total federal funding. Like HOMES, this is distributed to states and operated on a first-come, first-served basis once each state's program launches. But HEAR's per-household rebate amounts are large ($7,000 to $14,000 depending on income), meaning the money can be committed quickly once programs are fully operational.

2026 Status

HEAR programs began rolling out in 2024 and 2025, with many states launching point-of-sale rebates at participating retailers and contractors. Demand has been strong, particularly for heat pump HVAC systems and electrical panel upgrades. States with smaller populations and proportionally smaller allocations are projected to exhaust HEAR funds first.

Action Items

• If you are income-eligible (low-income or moderate-income), prioritize HEAR applications now
• Do not wait for your existing equipment to fail before applying; proactive replacement while funds are available is the smart move
• Check if your state requires pre-approval before purchase, and start that process immediately
• Ask contractors if they are registered as HEAR participating providers in your state

Section 30C: Alternative Fuel Vehicle Refueling Property Credit

Timeline

The 30C credit for EV charger installations ended for property placed in service after June 30, 2026. Residential installations qualify for a credit of up to $1,000 (30% of costs). The property must be in an eligible census tract (low-income community or non-urban area). This geographic limitation was added by the IRA and narrows eligibility compared to the previous version of 30C.

What This Means for 2026

If your charger was placed in service in an eligible census tract by June 30, 2026, you can still claim it on your 2026 return. Check eligibility by looking up your census tract on the Alternative Fuels Data Center website or ask our AI with your address. The annual credit resets each year, but since most homeowners only install one charger, this reset is less relevant than for 25C.

State and Utility Program Deadlines

Beyond federal programs, state and utility incentives have their own timelines:

State-Level Considerations

• State tax credits: These vary widely. Some states have permanent tax credits while others have sunset dates. New York's state solar credit, for example, has been extended multiple times but could expire
• State rebate programs: Many states fund rebate programs through utility surcharges or dedicated funds that are replenished annually. These programs rarely "run out" but may adjust rebate amounts from year to year
• SREC markets: Solar Renewable Energy Credit values fluctuate based on supply and demand within each state's market. Early solar adopters in SREC states benefit from higher initial credit values

Utility-Level Considerations

• Annual rebate budgets: Most utilities set annual rebate budgets. Programs that are popular may exhaust their budget mid-year and reopen the following January
• Net metering changes: Several states are reviewing net metering policies. If your state is considering changes (as California did with NEM 3.0), installing solar before the policy change preserves your rate structure under grandfathering rules
• EV charger utility rebates: Many utilities offer $200 to $500 for Level 2 charger installation, often with annual caps on the number of rebates issued

When to Act: Priority Matrix

The Bottom Line for 2026

The most urgent action items for 2026 center on the HEAR rebate program. If you are income-eligible and considering a heat pump, heat pump water heater, or electrical panel upgrade, apply now before state funding is exhausted. These are the largest point-of-sale rebates available and they will not be replenished once gone.

The federal tax credits (25C, 25D and 30C) have ended for new work, so the deadlines that matter now are HEAR, HOMES, state and utility program funding windows. Many of these are first-come, first-served and require approval before work starts.

For HOMES rebates, the urgency is moderate. Funds are still available in most states, but they are finite. If you are planning a whole-home efficiency project, get your energy audit done in 2026 even if construction will not begin until later.
