2026 EV Tax Credit Is Gone: What Expired, What Survives Briefly, and What’s Left of Clean Energy Credits

No. The federal EV tax credit under IRC §30D ended on September 30, 2025. Any electric vehicle placed in service on or after October 1, 2025 generates no federal credit, and that includes every vehicle you might buy in 2026. The credit didn’t taper down to a smaller amount; it stopped completely. If you’ve seen anything claiming there’s a reduced 2026 EV credit or a partial credit, that’s incorrect under current law as enacted in the One Big Beautiful Bill Act.

The credit you might still be able to claim is on a 2025 return, for a vehicle that was placed in service before October 1, 2025. Placed in service has a specific meaning — it’s when title transferred and you took possession, not when you signed a purchase contract or made a deposit. If you bought an eligible EV in July 2025 and drove it home in August 2025, you can claim up to $7,500 on your 2025 federal return filed in 2026. The forms haven’t changed; you still file Form 8936 with the return, attach the seller’s report (the document the dealer gave you at purchase confirming the VIN and the credit amount), and reconcile any point-of-sale transfer you took.

A common misconception is that the credit survives in some form for used EVs. The previously-owned clean vehicle credit at §25E ended on the same September 30, 2025 cutoff as the new vehicle credit. Used EVs purchased on or after October 1, 2025 don’t qualify either. The full slate of consumer-facing EV credits hit the same wall.

Another mistake we see is taxpayers who took the point-of-sale dealer transfer on a vehicle that didn’t actually qualify — usually because their income exceeded the limit ($150,000 single, $300,000 joint), the vehicle’s MSRP was over the cap, or the placed-in-service date slipped past the cutoff. If you took a $7,500 dealer discount as a point-of-sale credit transfer and you don’t actually qualify, you owe the IRS the $7,500 back as additional tax when you file the 2025 return. This shows up as a recapture on Form 8936. The dealer doesn’t refund the money to the IRS; you do, on your tax return.

Dollar specifics: the §30D credit was up to $7,500, split between two components — $3,750 if the critical minerals requirement was met and $3,750 if the battery components requirement was met. Some 2025 vehicles only met one, so the actual credit was $3,750. The income limits were modified adjusted gross income at or below $150,000 for single filers, $225,000 for head of household, and $300,000 for married filing jointly, using either the current year or the prior year’s MAGI — whichever was lower. MSRP caps were $55,000 for cars and $80,000 for SUVs, vans, and pickup trucks.

Documentation matters even for closed credits. If you’re claiming a §30D credit on a 2025 return, you need the seller’s report (sometimes called the clean vehicle credit report), the VIN, evidence of the placed-in-service date (delivery paperwork, title transfer date), and proof that the vehicle meets the assembly and sourcing requirements (the IRS-published list of qualifying vehicles is the easiest reference). Keep all of this in your tax file. If the IRS audits the credit two or three years from now, this is the documentation that supports the claim.

Audit risk is higher than normal on closed credits, particularly in transition years. The IRS knows that some taxpayers will try to claim the credit on a 2026 return for a 2026 purchase, and the matching against the dealer’s clean vehicle credit reports (which are submitted to the IRS for every qualifying sale) makes those bogus claims easy to identify. Don’t let a tax preparer claim the credit on a 2026 return for a 2026 vehicle. It’s wrong, it’ll get flagged, and you’ll owe back tax, interest, and possibly an accuracy-related penalty.

State and local incentives are a separate question. Many states maintain their own EV credits or rebates, and those programs operate independently of the federal credit. New York has the Drive Clean Rebate, California has the Clean Vehicle Rebate Project (status varies by funding cycle), and several other states have programs of their own. The federal credit is gone, but the state programs may still be relevant to your purchase analysis.

What about leases? The credit on leased EVs flowed differently than the credit on purchased EVs. Under the §45W commercial clean-vehicle credit (which was the credit the leasing company claimed on a leased EV), the leasing company often passed some of the $7,500 through to the lessee as a cap-cost reduction. That arrangement ended on the same September 30, 2025 cutoff. New leases originated in October 2025 or later don’t have the federal credit baked into the lease pricing anymore. Lease payments on existing pre-cutoff leases continue under the original terms, but the pricing on new leases reflects the loss of the federal credit.

One more wrinkle for clients who think the credit might still exist somewhere: the Inflation Reduction Act of 2022 made the credit available through the end of 2032 under the prior statute. Many EV buyers and dealers were operating under the assumption that the credit would be around through 2032. The OBBBA accelerated the sunset by seven years. If you saw informational material about EV credits published in 2023 or 2024 that referenced a 2032 end date, that material is now stale. The September 30, 2025 cutoff is the operative date.

Trade-in credits and dealer-discount layering: in 2024 and 2025, many EV buyers stacked the federal §30D credit with state rebates, manufacturer cash discounts, and trade-in equity. The federal credit allowed dollar-for-dollar reduction of the purchase price (through the point-of-sale transfer mechanism) without affecting any of the other discounts. Post-cutoff buyers in 2026 can still stack state and manufacturer incentives, but lose the federal layer. We’ve seen the total stacked discount on a 2025 purchase reach $12,000 to $15,000 for some buyers; the 2026 equivalent stack on the same vehicle is now $5,000 to $7,500 less because the federal piece is gone.

We can walk through both the federal and state-level analysis on your individual tax return, and the broader sunset picture is covered in the 2026 tax changes complete guide.

It ended completely. There’s no phase-down, no reduced credit amount for 2026, and no transition rule that gets you a partial credit on a 2026 purchase. The OBBBA terminated §30D, §45W, and §25E (the used-EV credit) as of September 30, 2025, with no successor credit on the consumer side. This is different from what some other tax credits did historically — the prior solar investment credit, for example, stepped down from 30% to 26% to 22% over several years before ending. The EV credit didn’t get that treatment.

The reason this matters is that some clients are still in a wait-and-see posture, assuming Congress will pass something else to replace the EV credit in 2026 or 2027. We’re not betting on that. The OBBBA was the major tax legislation of 2025, and it explicitly ended the EV credits. A replacement credit would require new legislation, and the political appetite for that isn’t visible from where we sit. Plan on no federal EV credit for 2026 and beyond. If something changes, we’ll update.

The technical citation is IRC §30D(h), which was amended by the OBBBA to add a termination date of September 30, 2025 for placed-in-service eligibility. The IRS hasn’t issued post-termination guidance because there’s nothing to guide — the credit simply isn’t available for post-cutoff vehicles. Form 8936 instructions for the 2025 filing year will reflect this, and the form for the 2026 filing year will likely not even include §30D as an active credit.

There’s a separate question about whether existing inventory of unsold 2024 and 2025 model-year EVs that dealers are sitting on can somehow qualify post-cutoff. The answer is no. The credit is based on when the buyer places the vehicle in service, not when the manufacturer produced it or when the dealer received it. A 2024 model-year EV sitting on a dealer lot on October 1, 2025 generates no credit when sold in November 2025, even though it’s still technically a current-model-year vehicle.

We’ve seen one creative argument floated — that the §30D credit might survive in some reduced form through a regulatory backdoor in the OBBBA’s transition rules. That’s not how the statute reads. The amendment was a hard date, and Treasury can’t restore the credit through regulations. If something changes, it’ll be through new legislation, not through Treasury guidance.

Dollar specifics for the (now-closed) §30D credit: maximum of $7,500 per vehicle, split into two $3,750 components based on critical minerals sourcing and battery components sourcing. Some manufacturers’ vehicles qualified for the full $7,500; others only qualified for $3,750 because they only met one of the two sourcing tests. The credit was nonrefundable for the regular tax claim (you needed at least $7,500 of tax liability to use the full credit) but could be transferred to the dealer at point of sale for a price reduction, in which case the nonrefundability didn’t apply — the dealer absorbed the credit and reduced your purchase price, regardless of whether you had any tax liability.

Common mistake: confusing the §30D consumer credit with the §45W commercial credit. Some businesses bought EVs through their corporate structure and tried to claim both — you can’t double-dip. A vehicle qualifies under §30D or §45W, not both. The choice typically came down to which credit was larger for the specific vehicle and how the business was structured.

Audit exposure: in transition years, the IRS pays close attention to credits that recently expired. The matching system between the dealer’s seller’s reports (filed with the IRS for every qualifying sale) and the taxpayer’s Form 8936 makes it easy to identify both bogus claims (claims on non-qualifying vehicles) and missed claims (taxpayers who took a point-of-sale transfer but didn’t file Form 8936 to reconcile). For 2025 returns, expect IRS notices on both fronts in late 2026 and 2027.

Documentation specifics: for any 2025 §30D claim, the file should contain the dealer’s seller report (which the IRS receives separately), the purchase agreement showing the VIN, the title transfer paperwork showing the placed-in-service date, MAGI documentation (W-2s and prior-year 1040 to support the income limit calculation), and Form 8936 with the supporting Schedule A. If you took the point-of-sale transfer, the transfer election paperwork from the dealer is also part of the file. We’ve seen the IRS request all of this in audit selection for transferred-credit returns, and missing documentation is a quick path to credit denial.

Pricing-related quirk: dealer pricing in October 2025 onward reflected the absence of the credit, but inventory pricing in late September 2025 was extraordinarily favorable. Buyers who closed before the cutoff often got both the credit and a discount from manufacturers/dealers clearing inventory ahead of the sunset. That dynamic is over. New EV pricing in 2026 reflects market dynamics without the federal subsidy, which has shifted the breakeven analysis on EV-vs-ICE purchases for many buyers.

What does survive in 2026? On the clean-vehicle and clean-energy side, only the §30C refueling property credit and the §45L new homes credit make it through June 30, 2026, and §179D continues for construction commenced before July 1, 2026. Everything else on the consumer side is done.

Looking ahead, the question we get most often is whether Congress will revive the credit through later legislation. Our honest answer: we don’t know, and we wouldn’t bet on it. The political and budget environment that produced the OBBBA termination wasn’t a one-off; it reflects a substantive disagreement over whether the federal government should be subsidizing EV adoption at the rates seen in 2023 through 2025. If the credit comes back, it’s likely to look different — tighter income limits, different vehicle eligibility, possibly different structure entirely. Plan your purchase based on current law, not on hypothetical future legislation.

A historical reference point worth knowing: the federal EV credit has been ended and revived in various forms before. The original §30D credit (under the Energy Improvement and Extension Act of 2008) was phased out per-manufacturer as each manufacturer hit a cumulative sales cap. That structure ended in 2022 when the Inflation Reduction Act replaced it with the income-and-MSRP-based credit that just expired. The credit has been through multiple iterations, and the consistent pattern is that each iteration has its own rules, its own cutoffs, and its own transition issues.

One subtle point: the credit’s death doesn’t change the underlying tax treatment of any state credits or rebates you might still receive on a 2026 purchase. State EV credits are generally either nontaxable rebates (which don’t affect federal taxable income but do reduce the basis of the vehicle for depreciation purposes if used in business) or taxable income (if structured as a credit against state income tax with refundability). The federal-state interaction is worth confirming on the return. We’ve seen state credit programs structured both ways, and the correct federal treatment depends on which structure your state uses.

We help clients work through the cleanup on 2025 returns (individual tax returns) and the broader sunset picture is in the 2026 tax changes complete guide.

Yes, but only a few, and most of them have short runways. The credits that survive into 2026 are: the alternative-fuel vehicle refueling property credit (§30C) through June 30, 2026; the new energy-efficient homes credit (§45L) through June 30, 2026; the energy-efficient commercial building deduction (§179D) for construction that begins before July 1, 2026; and the utility-scale clean-electricity credits (§45Y and §48E) under a more complicated tapered phase-out tied to construction-start and placed-in-service dates.

For most individual taxpayers, the §30C refueling property credit is the relevant one. If you install a Level 2 home EV charger between January 1, 2026 and June 30, 2026, you can claim 30% of the cost (up to $1,000 for residential property) as a federal tax credit on your 2026 return. The credit also covers commercial alternative-fuel refueling installations — chargers at workplaces, retail locations, fleet depots, and the like — with a higher cap structure for business installations. The IRS guidance is at irs.gov/alternative-fuel-vehicle-refueling-property-credit.

The §30C credit also has a geographic eligibility requirement that’s been in place since 2023: the refueling property has to be located in an eligible census tract, which is generally a low-income community or a non-urban area. The IRS published a mapping tool to help taxpayers verify whether their address qualifies. Before installing a home charger and assuming the credit will apply, check the address against the eligible tract list. If you’re not in an eligible tract, no credit.

On the residential side, §25D (solar, batteries, geothermal, small wind) is gone for 2026. §25C (insulation, windows, heat pumps, home audits) is gone. The §45L credit is a builder credit, not a homeowner credit — so even though it survives through June 30, 2026, you as a homeowner don’t claim it. The builder of a new home does. If you’re buying a new energy-efficient home from a builder in early 2026, the builder may pass some of the §45L benefit through to you in pricing, but the actual credit is on the builder’s return, not yours.

§179D is a deduction for energy-efficient commercial building improvements, claimed by the building owner (or, for public-sector buildings, allocated to the designer). The dollar amounts in 2025 went up to $5.81 per square foot for the highest energy-savings tier, with smaller amounts for partial qualification. For construction commencing before July 1, 2026, §179D continues to apply.

Dollar specifics on the surviving credits: §30C is 30% with caps ($1,000 for residential property; up to $100,000 per item for business property, subject to a depreciation-adjusted credit base for business installs). §45L is up to $5,000 per single-family or manufactured home meeting Zero Energy Ready Home certification, $2,500 for ENERGY STAR-certified homes, with a different tiered structure for multifamily. §179D is up to $5.81 per square foot (2025; adjusted annually for inflation through the cutoff).

Documentation requirements for these credits: §30C requires the installer’s invoice, the address (to verify the eligible census tract), and the manufacturer’s certification. §45L requires third-party energy certification (typically through a HERS rater for single-family homes, a certified rating program for multifamily). §179D requires a qualified third-party verification of the energy savings calculation, plus documentation of when construction commenced. None of these are credits you can claim on a back-of-the-envelope basis — they all require formal certification documentation.

Audit risk: §179D historically has had higher audit risk than typical, partly because the dollar amounts can be significant and partly because the construction-start documentation in transition years is unsettled. We expect §179D claims with construction-start dates in spring 2026 to attract scrutiny. Document everything: building permits, signed construction contracts, mobilization invoices, foundation work, physical work test evidence.

Practical timeline for a 2026 §30C residential install: most local jurisdictions require a permit for a Level 2 charger install (especially if the existing service panel needs upgrading). Permit timelines vary from a few days in permissive jurisdictions to several months in restrictive ones. If you’re planning a 2026 install to claim §30C, work backward from the June 30, 2026 cutoff: permit application by March or April 2026, install completed by May or early June, placed-in-service before the cutoff. Cutting it close to June 30 is risky because of inspection scheduling delays.

Don’t forget the eligible-census-tract rule on §30C. The IRS published the eligible tract mapping at irs.gov as part of the original IRA setup, and the mapping was updated with the 2024 census data refresh. A property that was eligible in 2023 might not be eligible in 2026 if the underlying census tract designation changed. Before assuming the credit applies to your address, check the current eligible tract list. Some traditionally non-urban or low-income areas don’t actually qualify under the IRS definition.

Recapture risk on previously claimed credits: §30D has a recapture rule (under IRC §30D(f)(5)) that applies if the vehicle is converted from personal to non-qualifying use within a certain timeframe. The credit must be recaptured (added back to tax) in proportion to the disqualified use. This rule continues to apply to pre-cutoff vehicles even though new credits aren’t being granted post-cutoff. A taxpayer who claimed the $7,500 credit on a 2024 purchase but sold the vehicle (or converted it to non-eligible use) within a short period may face recapture exposure on the 2025 or 2026 return. The §25D residential credit has its own basis-reduction and recapture rules tied to property dispositions; these continue to apply to pre-cutoff installations.

Carryforward of unused §25D credit into 2026 and beyond: even though §25D ended for property placed in service after December 31, 2025, taxpayers with unused credit from 2025 placed-in-service property continue to carry the unused amount forward into future tax years. A $9,000 §25D credit claimed on a 2025 solar install that exceeded 2025 tax liability creates a carryforward into 2026 and 2027 returns. That carryforward isn’t affected by the credit’s termination — the unused amount continues to be usable in later years against tax liability. Documentation of the original placed-in-service date and credit amount stays in the tax file as long as the carryforward is being used.

If you’re planning a 179D-eligible project, talk to us early about the documentation strategy. The same approach helps on the §30C and §45L side — build the certification file as you go, not after the fact. Our business tax services include the analysis of which credits apply and the documentation review, and the broader picture is in the 2026 tax changes complete guide.

Only if the solar system was placed in service on or before December 31, 2025. The residential clean-energy credit at IRC §25D ended for property placed in service after that date. If your panels were on the roof and producing electricity (utility interconnection approved, permission to operate granted) by December 31, 2025, you claim the 30% credit on your 2025 return filed in 2026. If your system wasn’t placed in service until 2026, no federal credit.

The placed-in-service test is the entire ballgame here. Signing a contract in November 2025 isn’t enough. Making a down payment isn’t enough. Having panels physically on the roof isn’t enough if the system isn’t operational. The IRS uses a strict standard: the system must be in a condition of readiness and availability for its intended use as of the placed-in-service date. For residential solar, that practically means utility interconnection approval and permission to operate.

We’ve worked with clients in late 2025 who scheduled installations in October and November and were waiting on utility interconnection through year-end. The utility queues in some service areas were running long — six to ten weeks in heavily-permitted markets — which created a real risk that systems installed in October wouldn’t be interconnected until January. If your system was caught in that queue and didn’t get permission to operate by December 31, 2025, no federal credit. The installer can’t fix this for you after the fact.

If your system was placed in service by December 31, 2025, the credit is 30% of the cost of qualified property, with no cap. Qualified property includes the solar panels themselves, mounting hardware, inverters, wiring, labor for installation and assembly, and battery storage (3 kWh capacity or larger) installed alongside the solar. Sales tax on the materials is included in the credit base. The credit is nonrefundable but the unused portion carries forward to future tax years — an important detail for taxpayers whose 2025 tax liability is smaller than the credit.

Common mistakes on 2025 returns claiming §25D: (1) taxpayers including the cost of work that doesn’t qualify (roof repair or replacement not directly related to the solar installation; tree removal; landscaping); (2) incorrect placed-in-service dates — using the contract date or the install date instead of the permission-to-operate date; (3) failing to claim battery storage that was installed in a separate phase before or after the solar (which can qualify on its own if the battery is at least 3 kWh and is installed at the residence); (4) double-counting state rebates — a state rebate reduces the credit base if it’s a non-taxable rebate, but doesn’t reduce the credit base if it’s a state credit or refund.

Dollar specifics: 30% credit, no cap on the credit amount, applies to expenditures placed in service before December 31, 2025. Includes solar electric (PV), solar water heating, fuel cell property (with a $1,667 per 0.5 kW cap), geothermal heat pumps, small wind energy, and qualified battery storage. The credit is claimed on Form 5695. Excess credit carries forward to future tax years without limit on years (under current law), which matters because a $30,000 solar system creates a $9,000 credit, and many homeowners don’t have $9,000 of tax liability in a single year.

Documentation needed: the contract with the installer, paid invoices showing the total cost, the manufacturer’s specifications for the panels and inverters (sometimes the installer provides a summary), the permission-to-operate letter from the utility (this is the placed-in-service evidence), any state or utility rebate documentation, and Form 5695. If you’re including battery storage, you need separate documentation showing the kWh rating of the battery. Keep all of this in your tax file for at least seven years — the IRS audit window on these claims is longer than the usual three years because of the carryforward of unused credit.

Audit risk: the IRS has been auditing §25D claims more aggressively over the past two years, particularly on systems claiming credits above $20,000. The common audit issues are (1) inflated costs (the IRS knows roughly what solar installations cost in different markets), (2) non-qualifying items in the credit base (roofing, structural work), and (3) placed-in-service date disputes. If the audit determines your system was placed in service in 2026 rather than 2025, the credit is denied entirely. There’s no partial credit, no transition relief, just denial.

If you’re in the position of having a 2025 system that didn’t get permission to operate until 2026, talk to us before filing. There may be facts that support a 2025 placed-in-service date even though the utility paperwork shows a 2026 date — or there may not be. We’d rather have that conversation before the return goes out the door.

Battery storage timing is its own analysis. Under the prior §25D rules, qualified battery storage (3 kWh or larger) installed at the residence qualified for the 30% credit even if installed separately from a solar system. If you installed a battery in 2025 (placed in service by December 31, 2025), the 30% credit applies on the 2025 return regardless of when the original solar was installed. A 2026 battery install, even at a residence with pre-existing 2024 solar, doesn’t qualify because §25D ended for property placed in service after 2025. This matters for homeowners who phased their installs across multiple years.

Multi-year payment scenarios: solar installs often involve a financing structure where the homeowner pays a portion at signing and the remainder over multiple years (or through a loan). The credit is based on total cost (including amounts financed), not on cash paid in the year. A $30,000 system financed over 10 years generates a $9,000 credit in the year the system was placed in service, not $900 per year over 10 years. The credit and the financing are independent — you claim the full credit up front, then pay the loan over time. If unused credit carries forward, that’s a separate issue from the financing structure.

Refinancing and credit treatment: some homeowners refinanced solar loans after the initial install, sometimes wrapping the solar financing into a HELOC or a cash-out mortgage refinance. The federal credit attaches to the placed-in-service event, not to the financing structure. Refinancing the solar loan in 2026 doesn’t generate any new credit on the 2026 return. If unused credit from the original install year is carrying forward, the carryforward continues regardless of how the system is now financed.

We handle these claims as part of individual tax returns, and the full clean-energy sunset picture is in the 2026 tax changes complete guide.

Four. The §30C alternative-fuel refueling property credit (through June 30, 2026), the §45L new energy-efficient homes credit (through June 30, 2026), the §179D commercial building deduction (for construction commencing before July 1, 2026), and the utility-scale clean-electricity credits at §45Y and §48E (under a tapered phase-out tied to construction-start dates). Each has its own rules and own cutoff structure.

For most small and mid-sized businesses, §30C and §179D are the relevant ones. §30C covers EV charging stations installed at your business location — whether that’s workplace chargers for employees, customer-facing chargers at a retail location, or fleet-charging infrastructure for company vehicles. Through June 30, 2026, the credit is 30% of qualifying costs (subject to caps that vary by installation size and depreciation-adjusted credit base), with the business version potentially reaching $100,000 per charger for large installations meeting prevailing wage and apprenticeship requirements.

§179D is the energy-efficient commercial building deduction — not a credit, a deduction. It applies to HVAC, lighting, and building envelope improvements that achieve certain energy reduction percentages versus the ASHRAE reference standard. The maximum deduction in 2025 was $5.81 per square foot. For 2026 construction commencement, the same dollar amount applies (subject to inflation adjustment in early 2026 announcements), as long as construction physically commences before July 1, 2026.

The §45L credit is specifically for builders of new homes — not for businesses occupying or renovating commercial space. If you’re a homebuilder selling certified energy-efficient homes (ENERGY STAR or Zero Energy Ready Home) through June 30, 2026, you can claim §45L on the qualifying homes. If you’re a non-homebuilder business owner, §45L doesn’t apply to your construction or renovation.

Common mistakes on the business side: (1) businesses installing EV chargers in non-eligible census tracts and assuming §30C applies — check the address against the IRS-published map before counting on the credit; (2) §179D claims without the required third-party verification of energy savings — this is a documentation-heavy deduction that absolutely requires a qualified verification report; (3) confusing §179D (a deduction) with §48 (an investment tax credit) — the two have different rules and cover different property; (4) overlooking prevailing wage and apprenticeship requirements that increase the §30C credit cap for larger commercial installations.

Dollar specifics: §30C is 30% of qualifying costs, with caps of $100,000 per item for business installations meeting prevailing wage/apprenticeship rules (much lower without). §179D is up to $5.81 per square foot at the highest tier (75% energy savings versus reference); reduced amounts for lower energy savings. §45L is up to $5,000 per Zero Energy Ready Home, $2,500 per ENERGY STAR-certified home, with separate multifamily tiers. §45Y and §48E are 30% base credit (utility-scale) with various adders for domestic content, energy community location, and prevailing wage compliance — potentially reaching above 50% for projects meeting all bonus criteria, though the tapered phase-out reduces those amounts based on construction-start year.

Documentation: §30C needs installer invoices, manufacturer specifications, eligible census tract verification, and (for business installs above the small-project threshold) prevailing wage and apprenticeship compliance records. §179D needs a qualified third-party verification of energy savings calculations, building permit documentation, and detailed records of construction-commencement evidence if you’re relying on the 2026 cutoff. §45L needs third-party HERS certification (single-family) or equivalent certification for multifamily. The utility-scale credits have their own substantial documentation requirements that are typically handled by the project sponsor and tax counsel.

Audit risk: §179D is the highest-risk of the four for typical small business taxpayers, mostly because of (1) the prevalence of cost-segregation-adjacent firms that pitch §179D as a cookie-cutter deduction without adequate energy-savings verification, and (2) the construction-start documentation issue in 2026. We strongly recommend that §179D claims in 2026 be supported by detailed construction-commencement evidence, including building permits, signed construction contracts, mobilization invoices, and any physical work test documentation. Treasury hasn’t released final guidance on what counts as construction beginning for §179D specifically, so we’re working from the analogous standards under §45 and §48.

If you’re a business considering one of these installations or projects, talk to us before signing the contract. The timing relative to the cutoff dates matters, and the documentation strategy needs to be in place from day one — not bolted on after the fact when the return is being prepared.

Direct-pay and transferability options on the surviving credits: §30C, §45L, §45Y, and §48E continue to support the direct-pay (elective payment) election for certain tax-exempt entities and the transferability election for taxable taxpayers. Direct pay turns the credit into a refundable payment for entities like 501(c)(3) charities, churches, and tribal governments that have no income tax liability. Transferability lets a taxable taxpayer with the credit sell it for cash to an unrelated buyer who can use the credit against their own liability. Both mechanisms have specific election procedures and registration requirements through the IRS pre-filing registration portal. If you’re a nonprofit considering EV charger installs through June 30, 2026, the direct-pay election on the §30C credit may make the economics work even though your organization has no income tax to offset.

Capitalization vs. expensing on §30C installations: the §30C credit is computed on the cost of the property, but the property itself is generally depreciable rather than immediately expensed (unless §179 or bonus depreciation applies). The credit reduces the depreciable basis of the property by 50% of the credit amount (under §50(c)). So a $20,000 EV charger install that generates a $6,000 credit has its depreciable basis reduced to $17,000. The interaction between the credit and depreciation needs to be modeled correctly on the return.

Investment in 2025 vs. 2026: if your business is choosing between completing a §30C or §179D project in late 2025 versus first-half 2026, the analysis isn’t symmetrical. A 2025 placed-in-service date locks in 2025 deduction or credit timing, but the 30% credit value on §30C and the maximum dollar values on §179D have been the same for the last several inflation cycles. A 2026 placed-in-service date (for §30C, before June 30, 2026) gets you essentially the same credit value with the additional flexibility of falling into the next tax year. We work through both options with clients based on their projected 2025 and 2026 tax positions.

We work through these credit and deduction questions as part of business tax returns, and the broader sunset picture is in the 2026 tax changes complete guide.
