S-Corp Clean Vehicle Credit: Why It Disappeared in 2025
If you bought a truck, van, or EV for the business and are still counting on a federal clean vehicle credit to show up on this year’s return, check the purchase date before you count it. Section 45W, which let an S-corp claim up to $40,000 toward an electric or plug-in work vehicle, ended for any vehicle acquired after September 30, 2025. If you’re filing a 2026 return and bought the vehicle after that date, the credit isn’t a timing issue or a form you’re missing. It’s gone.
What the Commercial Clean Vehicle Credit Used to Cover
Before the repeal, Section 45W let a business that placed a qualifying electric, plug-in hybrid, or fuel cell vehicle in service claim a credit worth the smallest of three numbers. The ceiling depends on the vehicle’s weight. A vehicle under 14,000 pounds gross vehicle weight rating topped out at a $7,500 credit; anything heavier, like a work truck or bus, could reach $40,000. The credit was also capped as a percentage of basis. A fully electric or fuel-cell vehicle capped the credit at 30% of its purchase basis, while a plug-in hybrid with a gas or diesel engine capped at 15%. The third test compared the vehicle’s incremental cost against a comparable model powered only by gas or diesel, using Department of Energy figures. Whichever of the three numbers was lowest set the actual credit, and the vehicle had to come from a qualified manufacturer and be used primarily for business in the United States.
The OBBBA Repeal Date for Vehicle Credits
The One Big Beautiful Bill Act, signed July 4, 2025, accelerated the termination of several energy provisions, and this credit was one of them. The IRS is direct about the cutoff: no credit is available for a qualifying vehicle acquired after September 30, 2025, and the same accelerated termination applies to the new and used clean vehicle credits under Sections 30D and 25E. Acquired doesn’t mean the same thing as delivered. If the vehicle was placed in service after September 30, 2025, the IRS still allows the credit only if you can show the vehicle was acquired on or before that date, meaning you entered a binding written contract and made a payment, even a deposit or trade-in, by then. Placed in service is the date you actually took possession. A truck put under a signed contract with a deposit down in August 2025 and delivered in November still qualifies under that test; one ordered in October 2025 does not, regardless of when it arrives. Keep the paper trail. A signed purchase order, the dealer’s contract, and proof of the deposit or trade-in are what substantiate the acquisition date if the IRS ever asks, so hold onto them with the vehicle’s title and depreciation records rather than assuming the invoice date alone will do.
How an S-Corp Claimed the Credit
For the vehicles that still qualify under the pre-cutoff rules, the mechanics matter for anyone amending a return or catching up a late filing. The IRS requires partnerships and S-corps to claim the credit on Form 8936, Clean Vehicle Credits, filed at the entity level. The credit then passes through to shareholders on their Schedule K-1s as a general business credit, which is nonrefundable but can carry over to future years if it exceeds the shareholder’s tax liability. There’s no cap on how many vehicles a business can claim the credit for, which made a multi-vehicle fleet purchase before the cutoff meaningfully more valuable than a single-vehicle one.
What’s Still Available for a Business Vehicle Purchase
Losing the clean vehicle credit doesn’t mean losing every tax benefit on a vehicle purchase. Depreciation didn’t go anywhere. Section 179 expensing and bonus depreciation still apply to a qualifying business vehicle regardless of whether it runs on electricity or gas, and OBBBA restored 100% bonus depreciation for qualifying property, which is often worth more than the old credit was on a heavier vehicle. See our breakdown of the S-Corp vehicle deduction rules for how the weight and use tests work. Mileage reimbursement is still the simpler path for a shareholder using a personal vehicle for company business, and that rate updates every year — our S-Corp mileage reimbursement post covers the current rate and the accountable plan paperwork it requires. Neither of these is new, but both are easy to overlook when a client was mentally budgeting around a credit that’s no longer there.
Don’t Let a Stale Assumption Drive the Purchase
The real risk here isn’t the lost credit itself, it’s the stale assumption behind it. A lot of the OBBBA provisions moved slowly enough that business owners are still planning around tax breaks that ended over a year ago, and a fleet purchase decision built on a $40,000 credit that no longer exists can throw off the entire return on investment. If your S-corp is weighing an electric or hybrid vehicle purchase, run the numbers on depreciation alone, not on a credit that’s been gone since September 30, 2025, and check whether your state still offers its own separate EV incentive, since several haven’t repealed theirs. For a closer look at how OBBBA reshaped the broader tax picture for S-corp owners, our OBBBA guide for S-corp owners is a good starting point. That’s especially true for a multi-vehicle fleet decision, where the difference between the old credit math and the current depreciation math can run into tens of thousands of dollars either way.
