Renewable Energy Tax Credits Under the Inflation Reduction Act for Business Owners

Renewable energy tax credits under the Inflation Reduction Act still give business owners large savings, but the One Big Beautiful Bill Act changed which opportunities are left. The useful distinction is between credits that have ended and credits that remain available. To claim the credits still available in 2026 and beyond, owners need to plan for project eligibility, labor and sourcing rules, cash conversion, and documentation before their choices become hard to undo.

How the One Big Beautiful Bill Act split IRA renewable energy credits into two groups

The One Big Beautiful Bill Act (OBBBA), Public Law 119-21, was signed on July 4, 2025. It accelerated termination dates across the IRA’s energy credit suite through budget reconciliation. Before the change, business owners and homeowners had been working with IRA provisions extending into the early 2030s, and many had made investment decisions on that basis.

The resulting division is broadly between consumer-facing incentives that ended during 2025 and business and manufacturing incentives that continue through 2026 and 2027. Each provision has its own rules for eligibility and its own cutoff, and some credits that have ended can still be claimed for earlier work that qualifies. Online material and advice from practitioners that still use the old 2032 sunset dates can lead owners to plan around the wrong deadlines.

Which credits ended and when business owners need to stop claiming them

For residential property, Sections 25C and 25D ended for property placed in service after December 31, 2025. Section 25C covered energy-efficient home improvements, including windows, doors, insulation, heat pumps, and home energy audits. Section 25D covered residential clean energy, including solar, battery storage, geothermal, and small wind. The placed-in-service date is the key distinction here. A plan to install qualifying equipment does not substitute for meeting that cutoff.

Vehicle credits use an acquisition date instead. Sections 30D and 25E, for new and used clean vehicles, ended for vehicles acquired after September 30, 2025. Section 45W can still be claimed for qualifying commercial clean vehicles acquired before October 1, 2025, if the credit was not claimed in tax year 2025. The end of eligibility for new purchases does not itself erase an eligible earlier claim.

Housing developers face a separate transitional deadline. Section 45L ends for homes acquired after June 30, 2026, including single-family, multifamily, and manufactured housing. For multifamily developers and federally regulated housing projects, certification and prevailing wage records can also affect the claimable amount. Work that qualified during 2022 through 2025 may also allow claims through amended returns for open tax years. The field for new investment is narrower, but it is not empty.

The credits that remain broadly available in 2026 and what each one covers

Electricity generators with qualifying facilities can look to Section 45Y, the Clean Electricity Production Tax Credit. It replaced the traditional production credit starting January 1, 2025, and is technology-neutral, applying to generation facilities with an anticipated greenhouse gas emissions rate of zero. Its value follows electricity production. The statutory rates are 0.3 cents/kWh generally or 1.5 cents/kWh with prevailing wage and apprenticeship compliance, subject to inflation adjustment.

Owners of generation facilities and energy storage systems that qualify can instead look to Section 48E, the Clean Electricity Investment Tax Credit. It replaced the traditional investment credit starting January 1, 2025, and is also technology-neutral. The distinction is the basis of the benefit. For projects at or above 1 MW AC, the credit is 6% of qualifying project cost without prevailing wage and apprenticeship compliance and 30% with compliance.

Manufacturers of solar modules, wind components, batteries, and critical minerals are the businesses served by Section 45X. It remains fully active in 2026, although it phases down later this decade. Carbon capture businesses, clean hydrogen producers, and clean fuels producers may qualify under Sections 45Q, 45V, and 45Z respectively. These credits require specialized technical qualification, including lifecycle emissions modeling for 45V.

Those six provisions are still broadly available through tax years 2026 and 2027, with claims governed by their rules and the OBBBA changes. Broad availability is not a universal project deadline. The IRA’s original 45Y phaseout framework was subsequently modified by the OBBBA, so its earlier timetable is not enough for planning. Operators of qualifying nuclear facilities placed in service before August 16, 2022, can also claim Section 45U.

How prevailing wage, apprenticeship, and domestic content requirements multiply the credit value

Prevailing wage and apprenticeship requirements, often called PWA, make labor compliance part of deciding what a project will cost. Take a solar project above 1 MW AC that qualifies. Under 48E, meeting PWA raises its investment credit from 6% to 30% before adding any domestic content or siting bonuses that apply. That difference can affect financial viability. Saving on labor overhead may leave the project with a higher net cost once the lost credit is counted.

Domestic content adds a separate qualification layer. A sufficient share of manufactured components must be U.S.-produced for the bonus to apply. The Congressional Research Service’s January 2025 domestic content report sets out how to measure manufactured product adjusted percentages and component-level cost assignments. Domestic content thresholds also affect direct payment amounts separately from their role in bonus eligibility.

Qualifying siting can add further value. Section 45Y offers bonuses of 0.3 cents/kWh each for domestic content and energy community siting. Under 48E, energy community and low-income bonuses that apply can stack with PWA and domestic content benefits, but separate rules apply to projects under 5 MW AC and qualified residential or economic benefit projects. Planning should model these conditions before contracts are signed, when labor, sourcing, and location decisions can still be shaped.

Credit transferability and direct pay turn credits into cash

A large credit is less useful to a business that lacks enough tax liability to absorb it. Section 6418 transferability addresses that mismatch. A business can sell all or part of an eligible credit to an unrelated buyer for cash at a negotiated discount. The seller receives a tax-exempt payment, while the buyer uses the purchased credit to reduce its own tax liability. For closely held businesses, this can convert otherwise stranded value into cash flow.

Direct pay serves a different group of recipients. Certain non-taxable entities, including state, local, and tribal governments, nonprofits, rural electric cooperatives, and the Tennessee Valley Authority, can receive payment from the IRS equivalent to an eligible credit amount. A federal environmental agency’s IRA summary explains that applicable entities elect to treat the credit as a refundable payment of tax, with any excess over tax liability paid directly. This can make eligible projects financially useful to nonprofit skilled nursing facilities and qualifying multifamily housing operators that owe no federal income tax.

The two routes broaden access without removing eligibility requirements. They also introduce recognition and valuation questions for financial reporting, particularly when credit receivables become significant balance sheet assets. For transfers, IRS pre-filing registration is a prerequisite. Advisors can help before the transaction takes place as well as record its tax result afterward.

The prohibited foreign entity rules create a compliance trap within surviving credits

The strongest qualification to the surviving-credit opportunity is supply chain eligibility. The OBBBA generally prohibits claims under Sections 45X, 45Y, and 48E where taxpayers receive material assistance from, or have certain ties to, foreign entities of concern. These include entities from China, Russia, North Korea, or Iran. The restrictions generally apply to taxable years beginning after July 4, 2025. Manufacturers and energy project owners may consequently face disqualification arising from relationships they have not fully mapped.

Domestic sourcing does not resolve every question. Global supply chain ties can complicate both domestic manufacturing and the sourcing of components assumed to qualify. A domestic content bonus analysis and a prohibited foreign entity analysis check different rules, though both need evidence from the supply chain.

The penalty rules sharpen that exposure. The OBBBA reduces the substantial understatement threshold from 10% to 1% when an understatement results from overstating the Material Assistance Cost Ratio for Sections 45Y, 48E, or 45X. It also extends the assessment period for deficiencies related to material assistance rules to six years. The appropriate planning response is supply chain due diligence and documentation to support claims for otherwise valuable credits.

What the IRS enforcement posture means for documentation and financial reporting

The IRS has moved from a “good faith” reporting posture toward “strict substantiation” for energy credits. Compliance campaigns, pre-filing registration requirements, and recent guidance signal greater scrutiny of eligibility evidence. These claims can depend on operational, engineering, environmental, and labor facts that sit outside the normal tax return process.

That breadth makes examinations unusually fact-intensive. Clean hydrogen lifecycle emissions modeling, for example, introduces technical methods that must support the claimed qualification. Third-party studies can themselves become subjects of scrutiny, while evolving guidance and new market entrants add further uncertainty. More is at stake when transferable and direct-pay amounts are large.

For finance teams, this is also a reporting issue. Credit receivables and deferred tax assets linked to IRA incentives can be significant enough to require close audit attention. Auditors must assess the underlying substantiation. Documentation thus connects credit capture to the supportability of the balance sheet, creating a role for assurance beyond preparation of the return.

How assurance engagements — financial statement audits, SOC examinations, and AI assurance — apply to IRA credit positions

Financial statement audits check whether there is enough evidence to support the credit amounts recognized. That evidence includes the calculation, prevailing wage records, domestic content documentation, and prohibited foreign entity analysis. Each supports a different part of eligibility. The 2026 financial statements need a close look for multifamily and federally regulated housing entities whose Section 45L credits stem from work that qualified before the June 30, 2026 cutoff. Nonprofits and skilled nursing facilities that use direct pay also need evidence for the amounts they recognize.

Service organization controls become relevant when outside providers underpin the claim or transfer. Credit transfer platforms, marketplace operators, and lifecycle modeling firms may handle data accuracy, credit valuation, or registration compliance. Their controls become part of the assurance chain. SOC 1 or SOC 2 examinations can provide independent assurance relevant to those services and user entity audits. SOC 2 examinations are also increasingly a procurement requirement as credit buyers assess the platforms and advisors they use.

AI introduces a further reliability question. Tools that calculate prevailing wage compliance, model emissions, or execute credit transfers can themselves become subjects of assurance. On October 19, 2026, the AICPA and the Artificial Intelligence Underwriting Company announced a joint offering combining a SOC 2 report and AIUC-1 certification in one CPA-led engagement. Both require annual renewal, and AIUC-1 requires quarterly technical retesting.

AIUC-1 addresses six risk pillars, including data and privacy, security, safety, reliability, accountability, and society. For energy service organizations that use AI, the bundled engagement covers both the usual procurement questions and concerns over how reliably the AI works. AI assurance addresses questions that substantiation may eventually raise, while financial audits and service organization examinations support the evidence already underpinning credit positions.

The proactive planning actions that capture the remaining window

For business owners, the next step is to map the available provisions against actual operations. Energy producers and project owners should assess 45Y and 48E, manufacturers should assess 45X, and carbon capture, hydrogen, and fuels businesses need the technical analysis relevant to their credits. Labor compliance deserves attention before project completion. Where projects remain in progress, the enhanced credit may justify restructuring contractor agreements. The same planning should include a review of the supply chain for prohibited foreign entity exposure and early transfer registration.

Earlier activity deserves a separate review. Open tax years from 2022 through 2025 may contain unclaimed residential or commercial energy benefits recoverable through amended returns. For multifamily 45L projects, that review should connect the acquisition cutoff with ENERGY STAR certification and prevailing wage evidence supporting the higher per-unit amount. Tax-exempt entities should also confirm registration and direct pay election procedures with an advisor before filing season. Filing on time is still part of getting the benefit.

A qualified CPA and advisory firm with energy credit, labor documentation, and financial statement audit knowledge can connect the tax, engineering, and compliance work throughout the year. That relationship leaves some risk and gives no guarantee of a particular credit outcome. It can help a business act while the opportunity remains, with evidence strong enough to support the value it expects to claim.
