As diesel prices across the country approach $7 per gallon, and Tesla's $290,000 Semi trucks finally begin to be delivered to paying customers, it's worth taking another look at how Trump's " One Big , Beautiful Bill Act " ( OBBA ) has strengthened the $179 deduction and how it can once again help your fleet move away from diesel more quickly.
The core of this approach is that IRS does not distinguish between fuel types; therefore, there are no separate depreciation categories for electric commercial trucks and diesel commercial trucks. The relevant classification depends on the vehicle's purpose and asset category. According to the depreciation guidelines of IRS, tractors designed for long-distance road transportation are classified as 3-year assets and are subject to a 20-year recovery threshold of 100% bonus depreciation. As a result, Tesla's electric Semi can benefit from the same Section of 179 as its diesel competitors.
However, this is not only beneficial for Tesla Semi buyers. Electric garbage trucks, electric dedicated work trucks, battery-powered refrigerated trailers, and even some large electric forklifts may also benefit from the same accelerated depreciation rules, as IRS classifies these vehicles as “specialized business vehicles”, without distinguishing between electric, diesel, natural gas, hydrogen energy, or any other form of power.
Since our initial articles, there have also been new developments in taxation. Earlier this year, IRS issued Notice for 2026-11, which provides further guidance regarding the permanent 100% recovery of qualified assets acquired after January 19, 2025. depreciation This means that eligible businesses may be able to combine the immediate expensing of Section at $179 with bonus and depreciation when ordering qualified fleet equipment, with "ordering" being the key factor. There are specific rules regarding when equipment is considered to have been acquired under a written, binding contract. Your tax professionals and truck dealers may be able to help you find ways to utilize these rules to your advantage.

After the commercial cleaning vehicle credit (Section 450,000) expired on September 30th, "experts" quickly predicted that sales of electric vehicles would slow down in the fourth quarter. However, with over 6,800 pages of provisions still available in the (Internal Revenue Code), the enhanced Section 179 tax deduction could still bring a strong year for commercial electric vehicles.
In 2025, the policies of “One Big” and “Beautiful Bill Act” (as well as OBBBA) undermined America's goals of energy independence and ensured that its automotive industry fell further behind China in the electric vehicle race. However, the elimination of the 45W incentive is not the only change in the IRS rule manual. The 179 deduction for business owners, which allows for immediate deductions for depreciable equipment assets, has been significantly expanded in 2025.
Section The 179 fee deduction applies to items such as automobiles, office equipment, commercial machinery, and computers. This rapid deduction can provide considerable tax savings for business owners purchasing equipment for starting a business.INVESTOPEDIA
The revised Section 179 tax credit (more accurately, a cost reduction) allows for a 100% deduction for equipment purchases, with the limit increased to $2.5 million; the deduction gradually decreases when capital investment reaches $4 million and drops to zero at $6.5 million. This policy can be applied to both new and used vehicles, as well as charging infrastructure, battery energy storage systems, specialized tools, and other items, as long as these assets are considered "new" to you.
Leveraging tax laws
"But wait," they often say, "there's more!" The revised Section 168(k) also allows for bonus depreciation of eligible equipment and property, thereby accelerating depreciation and reducing tax burdens.
Section 179 and bonus depreciation are not mutually exclusive, which means that companies do not have to exceed the expenditure limit of Section 179 to enjoy both benefits at the same time. Fleet operators can choose to expense a portion of the eligible vehicle or equipment purchases at Section 179, and then apply bonus depreciation to the remaining eligible base amount.
For qualified assets acquired after January 19, 2025, 100% of bonus and depreciation have been restored. This combination may allow a company to deduct the full qualified business usage costs of electric trucks or other commercial equipment in the first year, but it is still necessary to meet the applicable eligibility requirements and restrictions.
It’s a bit complicated (but what tax law isn’t?), but these tax incentives are good news for those companies that wish to purchase a sufficient number of electric equipment assets, thereby exceeding the Section expenditure limit of 179. Considering the new Uber / Tesla semi-trailer truck procurement plans, the continuous growth of the electric station tractor market, and the willingness of many utility companies to provide incentives for the deployment of electric commercial vehicles and intelligent EV charging infrastructure, this figure could be even higher than you think.

Tax law is quite peculiar. Not only are there federal tax laws and regulations that must be followed, but there are also rules at the state level, and even at the county and city levels. For this reason, you need to make sure they won’t “deal with” you in the same way they did with Capone back in those days.
Worse still, your favorite journalist (hi!) is most likely a fool as well. Please hire a certified accountant and a tax law expert to help you sort out the more complicated details of your specific situation – but don’t let the complexity of interpersonal interactions slow down your actions. The truly wealthy people you know often pay only a fraction of the taxes that you and I do, because they’re not afraid to seek help from accountants.
However, the shortest version is: there are still many incentives available in the market for fleet operators who wish to electrify their operations.
