If part of your 2026 plan assumed a federal tax break for going solar, buying an electric vehicle, or upgrading a building for efficiency, the ground has shifted under you. The clean energy credits 2026 landscape looks very different from the one that existed just a year earlier. Under the One Big Beautiful Bill Act, Congress ended most of the residential and vehicle incentives and set a hard clock on the commercial ones. This guide is for high-income earners, business owners, and real estate investors who want a clear, dated account of what expired, what is still available for a short window, and how to adjust plans that were built around benefits that no longer exist.
The short answer: most clean energy credits are gone
Here is the payoff first. The major individual clean energy tax credits, including the one for home solar and the ones for new and used electric vehicles, have been terminated. The commercial incentives were not all eliminated outright, but they now carry firm deadlines that close the door soon. In practice, a purchase you were weighing partly for the federal tax benefit generally needs a fresh look, because the credit that once supported that decision has either ended or is about to. The rest of this article walks through each credit, the code section behind it, and the date that matters.
Why the clean energy credits changed in 2026
The credits did not fade on their own. The One Big Beautiful Bill Act, signed in 2025, deliberately unwound a large part of the energy incentive structure that earlier legislation had expanded. Some provisions the law made permanent, such as the 20% qualified business income deduction and 100% bonus depreciation. Others, including this group of energy credits, it cut short. For the full picture of what the same law preserved and what it ended, our overview of the OBBBA 2026 tax changes high earners need to know connects the pieces.
The effect on planning is direct. When a credit is scheduled to phase out over several years, you have time to decide. When a credit is terminated on a specific date, the only question is whether you acted before that date. Most of the changes below fall into the second category, which is why timing now matters more than eligibility.
The residential clean energy credit under Section 25D is gone
The residential clean energy credit was the big one for homeowners. Under Section 25D, a homeowner who installed solar panels, solar water heating, geothermal heat pumps, small wind, or battery storage could claim a credit worth 30% of the cost, with no dollar cap. Earlier law had advertised that 30% rate as running through 2032. That timeline no longer holds.
The new law terminated the Section 25D credit for property placed in service after December 31, 2025. In plain terms, a residential solar system that was up and running by the end of 2025 could still qualify on the 2025 return, but a system installed in 2026 generally cannot claim the federal credit at all. For a typical solar project, the lost 30% credit is a real number, often several thousand dollars, so anyone who deferred an installation on the assumption that the credit would wait for them should recheck the math without it.
The IRS maintains the current details on its Residential Clean Energy Credit page. Because the termination turns on the placed-in-service date rather than the contract date, confirm the specifics with a licensed tax professional before relying on any credit for a late-2025 project.
The electric vehicle credits ended earlier than most expected
The vehicle credits closed even sooner than the home credit. The clean vehicle credit under Section 30D offered up to $7,500 on a qualifying new electric vehicle, and the used clean vehicle credit under Section 25E offered up to $4,000 on a qualifying pre-owned one. A separate commercial clean vehicle credit under Section 45W applied to business purchases.
Under the new law, these vehicle credits end for vehicles acquired after September 30, 2025. That date is worth reading twice, because it sits earlier in the calendar than the home credit deadline. A buyer who took delivery of a qualifying vehicle on or before that date may still have a claim, while a purchase in late 2025 or in 2026 generally does not qualify for the federal credit. If an electric vehicle was on your list and the tax credit was part of the appeal, the incentive has almost certainly lapsed, so evaluate the purchase on price, not on a credit that no longer applies.
Home energy efficiency credits also expired
The other household credit to disappear was the energy efficient home improvement credit under Section 25C. This one rewarded smaller upgrades: exterior doors, windows, insulation, and certain high-efficiency heating and cooling equipment. It carried annual limits, generally up to $1,200 a year for many improvements and up to $2,000 for qualifying heat pumps and similar equipment.
The law terminated the Section 25C credit for property placed in service after December 31, 2025, on the same timeline as the residential clean energy credit. The dollar amounts here were smaller than the solar credit, but the credit was popular precisely because ordinary maintenance projects qualified. For 2026 and beyond, treat those upgrades as ordinary home expenses, because the federal credit that used to offset part of the cost is no longer on the table.
Commercial incentives: Section 179D and the solar ITC phase-out
Business and real estate incentives followed a different path. Rather than a clean termination, several were given closing windows, which means a narrow group of projects may still qualify if the timing lines up.
The Section 179D commercial buildings deduction
The energy efficient commercial buildings deduction under Section 179D rewarded owners and designers who improved a building’s energy performance. The new law ends this deduction for construction that begins after June 30, 2026. Projects already underway before that date may still reach the deduction, but new commercial construction planned after it generally cannot. If you are a building owner or a design firm with a project on the calendar, the start date is the hinge, so confirm where your project sits relative to that cutoff.
The commercial solar investment tax credit
The commercial solar investment tax credit under Sections 48 and 48E is the one meaningful incentive that survives, though only briefly. It was not terminated outright. Instead, it is time-limited: qualifying projects generally must begin construction before July 5, 2026, and be placed in service before December 31, 2027. A business that can meet both dates may still capture the credit on a commercial solar installation. This is the narrow exception to an otherwise closing chapter, and it rewards owners who move deliberately rather than wait.

The table below summarizes each credit, the code section behind it, and the date that decides whether it applies. Treat it as a map rather than personalized advice, and confirm the current figures before you rely on any line.
| Credit or deduction | Code section | Status in 2026 | Key date |
|---|---|---|---|
| Residential clean energy (home solar, geothermal, storage) | Section 25D | Terminated | Placed in service after Dec 31, 2025 |
| Energy efficient home improvement (windows, insulation, HVAC) | Section 25C | Terminated | Placed in service after Dec 31, 2025 |
| New clean vehicle | Section 30D | Terminated | Acquired after Sep 30, 2025 |
| Used clean vehicle | Section 25E | Terminated | Acquired after Sep 30, 2025 |
| Commercial clean vehicle | Section 45W | Terminated | Acquired after Sep 30, 2025 |
| Energy efficient commercial buildings | Section 179D | Ending | Construction beginning after Jun 30, 2026 |
| Commercial solar investment tax credit | Sections 48 and 48E | Phasing out | Begin construction before Jul 5, 2026; in service before Dec 31, 2027 |
What this means for high-income earners
For high earners, the practical fallout is less about the credits themselves and more about the assumptions built on top of them. Several planning habits need a second look. The points below come up most often.
- Remove expired credits from your 2026 projections. If a tax estimate still assumes a solar or vehicle credit, it overstates your benefit and understates your bill. Update the numbers now rather than at filing time.
- Reprice deferred projects. A home solar system or an electric vehicle you postponed is now more expensive on an after-tax basis, because the federal offset is gone. The purchase may still make sense, but it should stand on its own merits.
- Check the one surviving window. If you own commercial property and a solar project is feasible, the investment tax credit remains available for a short period. That is the rare place where acting quickly can still capture a federal benefit.
- Do not chase a credit past its deadline. Structuring a late purchase to look like it qualifies invites problems. The dates are specific, and the safest course is to plan around the rules as written.
None of this means energy improvements are a poor idea. It means the tax code is no longer subsidizing them for individuals, so the decision returns to economics, utility savings, and personal priorities rather than a federal credit.
Where to redirect your planning instead
The end of the energy credits does not shrink the broader menu of legal tax strategies. If anything, it raises the value of the deductions the same law made permanent. A few areas are worth more of your attention now.
Business owners and real estate investors gained a durable tool when the law restored a full first-year write-off on qualifying assets. Our guide to how 100% bonus depreciation is now permanent explains what qualifies and how to time purchases, and for property owners it pairs naturally with a cost segregation study. That combination often delivers a larger current-year benefit than the energy credits ever did, though it depends on your income and entity. The point is that the levers that move a high earner’s tax bill were largely preserved, even as the energy incentives closed.
For a structured way to see which strategies fit your situation, this is where a coordinated plan earns its keep. A single missed credit is a minor issue when the rest of your plan is built on purpose rather than assembled at the last minute.
Planning moves to consider for the rest of 2026
Law changes only help if you act while the year is open. A short review now generally beats a scramble in April. The steps below are a starting framework, not a prescription.
- Audit your projections. Strike any residential energy, efficiency, or vehicle credit from 2026 estimates so your numbers reflect current law.
- Confirm 2025 claims. If you placed a system in service or acquired a vehicle before the relevant cutoff, make sure the credit is captured correctly on the right year’s return.
- Evaluate the solar ITC window. If you own commercial property, model whether a solar project can meet the begin-construction and placed-in-service dates.
- Shift focus to permanent tools. Revisit bonus depreciation, the QBI deduction, and entity structure, which now carry more weight in a high earner’s plan.
- Coordinate with a professional. Because most of these rules turn on specific dates, a brief review prevents a costly assumption.
The bottom line on clean energy credits in 2026
The clean energy credits that many households and businesses relied on have largely ended. The residential solar credit, the home efficiency credit, and the electric vehicle credits are terminated, while the Section 179D deduction and the commercial solar investment tax credit survive only inside closing windows. For high-income earners, the lesson is straightforward. Update any plan that assumed these benefits, evaluate deferred purchases on their real cost, and redirect your energy toward the permanent deductions the same law preserved. The households that adjust deliberately will feel the change far less than those who discover it at filing time.

Frequently asked questions
Can I still claim the home solar credit in 2026?
Generally no. The residential clean energy credit under Section 25D was terminated for property placed in service after December 31, 2025. A system that was operational by the end of 2025 may qualify on the 2025 return, but a 2026 installation typically does not receive the federal credit. Confirm your placed-in-service date with a licensed tax professional.
Is there any clean energy incentive left after 2026?
For most individuals, no. The main survivor is the commercial solar investment tax credit under Sections 48 and 48E, which remains available for business projects that begin construction before July 5, 2026, and are placed in service before December 31, 2027. It is time-limited, so eligibility depends on meeting both dates.
What should I do if I already bought solar or an electric vehicle?
Check the timing. If you placed a solar system in service or acquired a vehicle before the applicable cutoff, you may still be able to claim the credit on the correct year’s return. Because the rules turn on specific dates and your facts, review the claim with a qualified advisor to make sure it is captured properly.
