Clean Energy Credit Deadlines: What SMBs Missed and Can Still Get

#The honest version of where clean energy credits stand in 2026

Look, I get this question in a specific way. Nobody walks in asking about Section 45V hydrogen. They walk in asking some version of: “I’m putting solar on the shop, is the government still paying for part of it?”

The answer for tax year 2026 is yes, but with less time and more paperwork than the version they read about in 2023.

The Inflation Reduction Act built a large menu of clean energy incentives. The OBBBA, signed July 4, 2025, kept some, accelerated the phase-out on others, and killed a handful outright. What is left is not a smaller version of the same program. It is a program where the deadline is the eligibility test.

#What actually closed

“Most of the clean energy credits a normal small business would have used are already gone. The commercial EV credit closed to vehicles acquired after September 30, 2025. The charging station credit, the energy-efficient buildings deduction, and the new-homes credit all cut off at June 30, 2026. So when an owner asks me in the fall of 2026 whether they should buy an electric van for the tax credit, the honest answer is that the credit stopped being a reason to buy the van a year ago. Buy it if the van makes sense.” — Ramon Liriano Jr., Managing Partner, Elevated Tax Strategies

That is not a small point. A lot of clean energy content still on the internet was written before OBBBA and reads as if 2023 rules apply. Owners make five- and six-figure purchase decisions on that stale information, and then find out at filing that the window closed while they were shopping.

#What a small business can still realistically claim

Here is the part most roundups get wrong. They publish a list of twelve incentives and imply a small business might use any of them. In practice, most of the surviving credits pay you for producing energy, fuel, or components at industrial scale: 45Y, 45U, 45Q, 45V, 45Z, 40A(b)(4), 45X. Those are real credits with real money attached, and they are almost never the answer for a landscaping company, a dental practice, or a trucking outfit.

For an ordinary operating business, the list collapses to a much shorter one.

“There are eight clean energy credits still broadly available in 2026, but let’s be honest about who they are for. Most of them pay you to produce electricity, fuel, hydrogen, or manufactured components. If you run a dental practice or a landscaping company, that list is not your list. The two that actually reach an ordinary operating business are Section 48E, if you put solar or storage on a building you control, and the last of 179D if you already broke ground. Everything else is a headline you will never cash.” — Ramon Liriano Jr., Managing Partner, Elevated Tax Strategies

#The 5x multiplier, and the exemption most articles skip

Most of these credits are quoted at a base rate with a note that the amount increases up to five times if you meet prevailing wage and apprenticeship (PWA) requirements. On Section 48E, that is the difference between a 6% credit and a 30% credit. On a $200,000 solar install, that is $12,000 versus $60,000.

Here is the part that gets left out of nearly every roundup, and it is good news for small businesses: generation facilities with a maximum net output under 1 megawatt are exempt from PWA and get the 5x increase anyway. So do facilities that began construction before January 29, 2023.

That exemption is why the rule matters less than the headlines suggest for a typical Main Street project, and why it matters enormously the moment you cross the line.

“Almost every article about these credits tells small business owners they have to meet prevailing wage and apprenticeship rules to get 30% instead of 6%. For most of them, that is simply not true. Generation facilities under one megawatt are exempt and get the full amount automatically, and a rooftop solar system on a warehouse is usually a fraction of that. The rule bites when you cross one megawatt, and it bites on the 179D building deduction, which has no small-project exemption at all.” — Ramon Liriano Jr., Managing Partner, Elevated Tax Strategies

To put the threshold in perspective: 1 megawatt AC is roughly 1,000 kilowatts. A commercial rooftop array on a shop, clinic, or warehouse is commonly 50 to 300 kilowatts. Most small business solar is comfortably under the line. Larger ground-mount projects, multi-building portfolios, and anything approaching utility scale are not.

When you are over the line, or when you are chasing 179D, the compliance decision happens long before tax season.

“When PWA does apply, it is not a tax election you make in April. It is a contract you write before the first shovel moves. It means your contractor pays Department of Labor wage rates, uses registered apprentices for a set share of the hours, and hands you certified payroll to prove it. If that language is not in the contract, you are getting the base amount, not the five-times amount, and no accountant can fix that after the fact.” — Ramon Liriano Jr., Managing Partner, Elevated Tax Strategies

#The “beginning of construction” fight nobody warned you about

For wind and solar under 48E and 45Y, the practical deadline is not when your system turns on. It is when construction began.

Historically, taxpayers could establish that two ways: the physical work test, or the 5% safe harbor, meaning you incurred at least 5% of total project cost. The safe harbor was the easy, cheap, documentable one, and small projects leaned on it.

In August 2025, IRS Notice 2025-42 generally eliminated the 5% safe harbor for wind and for solar facilities above 1.5 megawatts, leaving the physical work test as the sole method. Then in June 2026, a federal district court vacated that notice as arbitrary and capricious and remanded it to the IRS, which technically restores the safe harbor, with an appeal likely.

If that sounds unsettled, it is. And that is exactly the point for a small business.

“The beginning-of-construction rule for solar has been litigated, vacated, and is probably going to be appealed. I am not going to tell a client to bet a six-figure project on how that appeal lands. Document both ways. Show real physical work of a significant nature, keep dated photos and signed work orders, and separately track that you incurred at least five percent of total project cost. Doing both costs you a folder. Doing neither costs you the credit.” — Ramon Liriano Jr., Managing Partner, Elevated Tax Strategies

#What the credit is actually worth after the math

A 30% credit is not a 30% discount. Two adjustments change the real number, and both surprise people.

Basis reduction. Under Section 50(c), the depreciable basis of investment credit property is reduced by half the credit. Take a 30% credit on a $200,000 solar array and your depreciable basis drops to $170,000. You still get the $60,000 credit. You just get less depreciation over the life of the asset. It is still strongly favorable. It is not the number on the brochure.

Recapture. Investment credits carry a five-year recapture period. Sell the building, sell the system, or take the property out of service early, and part of the credit comes back. For 48E specifically, the property can also cease to be investment credit property if the facility’s greenhouse gas emissions rate is later determined to exceed the statutory threshold.

There is a third one that catches individual owners specifically: if the activity is passive to you under Section 469, the credit can be a passive activity credit and get suspended rather than used this year. A credit you cannot use this year is not the same as cash. That is a conversation to have before you finance the project, not after.

#Selling the credit instead of using it

The IRA made several of these credits transferable. You can sell them to an unrelated buyer for cash, the payment you receive is not taxable income to you, and the buyer applies the credit against their own liability. Among the credits on the 2026 list, the transferable ones include 30C, 40A, 45Q, 45U, 45V, 45X, 45Y, 45Z, and 48E. Deductions like 179D cannot be transferred.

Transfer sounds like free money. It is not free. Credits sell at a discount to face value, and you pay transaction costs, legal review, and often credit insurance out of your side of the deal.

“Transferability is the right move when you do not have the tax liability to absorb the credit, and the wrong move when you do. You are selling a dollar for less than a dollar, plus legal and insurance costs on your side. If your business will owe real tax over the next few years, use the credit. If you have losses, credits stacking up unused, or a passive activity problem, then selling it for cash today beats holding a credit you might never absorb.” — Ramon Liriano Jr., Managing Partner, Elevated Tax Strategies

#How to actually capture one of these

#Common questions

Which clean energy incentives are already closed to a small business? Four that ordinary businesses would have used. Section 45W (commercial clean vehicles) closed to vehicles acquired after September 30, 2025. Sections 30C (EV charging equipment), 179D (energy-efficient commercial buildings), and 45L (new energy-efficient homes) cut off at June 30, 2026. Each can still be claimed for projects or purchases that qualified before its cutoff, which is why checking your dates is worth real money even now.

Did the OBBBA repeal the Inflation Reduction Act energy credits? Not entirely. It terminated some, accelerated phase-outs on others, and added new restrictions such as Foreign Entity of Concern rules and domestic content thresholds. The result is that the credits are more about timing and documentation than they used to be.

Can a sole proprietor still be blocked from using a clean energy credit? Yes, and entity type is not the reason. Sole proprietorships, single-member LLCs, partnerships, S corps, and C corps can all qualify if they own qualifying property and meet the requirements. What actually blocks an individual owner is the passive activity credit rules under Section 469, which can suspend the credit rather than deny it, so you hold a credit you cannot use this year.

How do I get the 30% rate instead of 6% on Section 48E? If your facility’s maximum net output is under 1 megawatt, you generally receive the increased amount automatically, with no prevailing wage or apprenticeship compliance required. Most small business rooftop solar falls here. Above 1 megawatt, you must meet prevailing wage and apprenticeship requirements and hold the records to prove it: Department of Labor prevailing wage rates for the trades and locality, registered apprentices for the required share of labor hours, and certified payroll. Put it in the installation contract before work starts. Note that the 179D deduction has no small-project exemption.

Does a clean energy credit reduce my depreciation? Yes for investment credits. Under Section 50(c), your depreciable basis is reduced by half the credit amount. A 30% credit on a $200,000 project reduces basis to $170,000. The credit is still worth far more than the lost depreciation, but the two need to be modeled together.

Should I sell a transferable credit or claim it? Claim it if your business will have enough tax liability to absorb it in a reasonable timeframe. Sell it if you are in losses, already carrying unused credits, or facing a passive activity limitation. Transferred credits sell at a discount and carry legal and insurance costs, so you are trading value for certainty and speed.

What if I already installed EV chargers or bought an electric van? Check your acquisition and placed-in-service dates against the cutoffs. Section 45W requires acquisition on or before September 30, 2025, and Section 30C requires the property to have been placed in service before July 1, 2026. If you qualified and did not claim it, that is worth reviewing, and in some cases amending.

How long do I need to keep the documentation? At minimum through the five-year recapture period for investment credits, and longer if you carry the credit forward. Keep the construction-start file, PWA certified payroll, equipment certifications, and proof of payment together as one package. Under exam, that file is the credit.

---

None of this is a reason to avoid a clean energy project. If solar on the shop pencils out on energy savings alone, the credit makes a good decision better. The mistake is the other direction: letting a credit talk you into a purchase, then losing most of the credit to a contract you signed without the right language in it.
