EV depreciation for income tax works the same way as it does for any business vehicle: if you use an electric car, truck, or SUV in a trade or business, you recover its cost through the Modified Accelerated Cost Recovery System over five years, with the option to accelerate that recovery using Section 179 expensing and 100% bonus depreciation. For a passenger EV placed in service in 2026, the first-year deduction is capped at $20,300 when bonus depreciation applies. Heavier electric trucks and SUVs rated above 6,000 pounds gross vehicle weight escape that cap and can often be written off in full the first year.1Internal Revenue Service. Rev. Proc. 2026-15
You Need Business Use to Depreciate an EV
Depreciation is only available for property used in a trade or business or held to produce income.2Office of the Law Revision Counsel. 26 USC 167 – Depreciation A personal commuter EV generates no deduction. Self-employed rideshare drivers, real estate agents, and business owners who visit clients qualify. Employees who use a personal EV for unreimbursed work travel may also qualify under narrower rules.
Business use is measured as a percentage of total miles for the year, and that percentage governs every dollar of your deduction. Drive 70% for business, and you get 70% of the write-off. The IRS expects contemporaneous mileage records, and rounding up is a fast way to lose the deduction in an audit.
The 50% Threshold
To use any accelerated method, including bonus depreciation and Section 179, your business use must exceed 50% of total mileage for the year.3eCFR. 26 CFR 1.280F-6 – Special Rules and Definitions Fall below that line, and you’re restricted to straight-line depreciation over a longer recovery period. If business use drops under 50% in a later year after you’ve already claimed accelerated deductions, the excess depreciation gets recaptured as ordinary income in the year of the drop. That is worth thinking about before front-loading deductions on a vehicle whose business role may shrink.
Figuring Your Depreciable Basis
Start with the total cost of acquiring the vehicle: purchase price, sales tax, delivery, and any other fees paid to put it on the road. Two adjustments follow.
First, if you claimed the federal Clean Vehicle Credit under Section 30D, reduce your basis by the full credit amount.4Office of the Law Revision Counsel. 26 USC 30D – Clean Vehicle Credit A $55,000 EV with a $7,500 credit has an adjusted basis of $47,500. Skipping this step overstates every year’s deduction.
Second, multiply that adjusted basis by your business use percentage. The $47,500 basis on a vehicle driven 80% for business produces a depreciable basis of $38,000. The personal share is never recoverable.
The Three Methods That Stack
Most taxpayers who want maximum first-year deductions combine all three tools.
MACRS Five-Year Recovery
Passenger automobiles are five-year property under MACRS, spread across roughly six calendar years using a declining-balance method that concentrates deductions in the earlier years.5Office of the Law Revision Counsel. 26 USC 168 – Accelerated Cost Recovery System Even without special elections, MACRS gives you bigger deductions in years one and two than later.
Section 179 Expensing
Section 179 lets you deduct the full cost of qualifying business property in the year you place it in service instead of spreading it out. Passenger automobiles remain subject to the annual depreciation caps below, so Section 179 alone does not break the cap for a sedan. Where it matters is heavier vehicles.
100% Bonus Depreciation
Following the enactment of the One, Big, Beautiful Bill in mid-2025, bonus depreciation permanently returned to 100% for qualifying property acquired after January 19, 2025.6Internal Revenue Service. Treasury, IRS Issue Guidance on the Additional First Year Depreciation Deduction Amended as Part of the One Big Beautiful Bill For EVs placed in service in 2026, you can deduct the entire depreciable cost in year one, still subject to the passenger auto caps. Bonus depreciation applies automatically unless you affirmatively elect out.
Annual Caps for Passenger EVs (2026)
Federal law caps the annual depreciation deduction on any “passenger automobile” no matter what the vehicle actually cost. These caps apply the same to gas and electric vehicles. For EVs placed in service in 2026:1Internal Revenue Service. Rev. Proc. 2026-15
With bonus depreciation:
- Year 1: $20,300
- Year 2: $19,800
- Year 3: $11,900
- Each year after: $7,160
Without bonus depreciation:
- Year 1: $12,300
- Year 2: $19,800
- Year 3: $11,900
- Each year after: $7,160
Each cap is reduced proportionally when business use is below 100%. A $60,000 EV used 75% for business has a first-year ceiling of $15,225 with bonus depreciation. Because of these caps, an expensive passenger EV takes more than five years to fully depreciate; you keep claiming $7,160 per year (adjusted for business use) until the basis is exhausted.
Heavy Electric Trucks and SUVs Escape the Caps
The Section 280F caps only apply to “passenger automobiles,” defined as four-wheeled vehicles rated at 6,000 pounds gross vehicle weight or less.7Office of the Law Revision Counsel. 26 USC 280F – Limitation on Depreciation for Luxury Automobiles Electric trucks and SUVs above that threshold are free of the annual caps. With 100% bonus depreciation back in force, the owner of a qualifying heavy EV can potentially deduct the full business-use portion of the vehicle’s cost in year one.
SUVs with a GVWR between 6,000 and 14,000 pounds have their own Section 179 cap of $32,000 for 2026. Any remaining cost above that ceiling can be covered by bonus depreciation, often producing a complete first-year write-off anyway. Heavy trucks and vans over 6,000 pounds that aren’t classified as SUVs face no vehicle-specific Section 179 cap at all.
Several popular electric models cross the 6,000-pound line, including the Tesla Model X, Rivian R1T and R1S, and certain Audi and BMW plug-in hybrid SUVs. Look at the manufacturer’s gross vehicle weight rating on the door jamb specification sheet, not curb weight. GVWR includes maximum loaded capacity and is always higher.
Depreciation vs. the Standard Mileage Rate
You can’t claim both depreciation and the standard mileage rate on the same vehicle. The 2026 business mileage rate is 72.5 cents per mile and applies to EVs identically to gas vehicles.8Internal Revenue Service. IRS Sets 2026 Business Standard Mileage Rate at 72.5 Cents per Mile, Up 2.5 Cents That rate bundles depreciation, electricity, insurance, and repairs into a single per-mile figure. It is simpler, but for an expensive EV with heavy business use, the actual expense method with depreciation almost always beats it in the early years.
Year one is the deciding moment. If you want the standard mileage rate, you have to pick it in the first year the vehicle is available for business use, and you can switch to actual expenses later. Claim depreciation or Section 179 in year one, and you’re locked into actual expenses for the life of the vehicle. Leased EVs are stricter: whichever method you pick applies for the entire lease period.
What Happens When You Sell the EV
Depreciation is a benefit now and a tax bill later. A business EV is Section 1245 property, so any gain on sale attributable to depreciation you previously deducted is recaptured and taxed as ordinary income at your marginal rate.9Office of the Law Revision Counsel. 26 USC 1245 – Gain From Dispositions of Certain Depreciable Property There is no 25% rate cap the way there is for real estate. A high-income taxpayer could see the recapture taxed at 37% federally.
The math: subtract total depreciation claimed from your original cost to get adjusted basis. Sell for more than that, and the gain up to the amount of depreciation taken is ordinary income. Any gain beyond total depreciation may qualify for long-term capital gains treatment if you owned the vehicle more than a year. Sell at a loss, and there is no recapture; the loss on the business-use portion is deductible as an ordinary loss, while any loss on the personal-use portion is not deductible at all. Report the sale on Form 4797.10Internal Revenue Service. About Form 4797, Sales of Business Property
EVs currently hold their value better than many gas vehicles, which makes recapture bite harder than people expect. Deduct $40,000 in depreciation, then sell for only $15,000 less than you paid, and you owe ordinary income tax on $25,000 of recaptured depreciation. Weigh that before choosing an aggressive first-year strategy over a slower schedule.
Records and the Form You File
The IRS wants contemporaneous records, meaning trips logged at or near the time they happen rather than reconstructed the following April. Each business trip entry needs the date, starting point and destination, business purpose, miles driven, and odometer readings at the start and end of the tax year. “Client meeting” is not enough; note the client and the reason.
Beyond the mileage log, keep the purchase contract, financing paperwork, and any documents showing total cost with sales tax and delivery. If you claimed the Clean Vehicle Credit, keep records of the credit amount, since your basis depends on it. Hold on to all of this for at least three years after the final depreciation deduction; for a passenger EV under the annual caps, that can run well past the nominal five-year recovery period.
Report the deduction on IRS Form 4562, which asks for the vehicle description, cost basis, business use percentage, and depreciation method elected.11Internal Revenue Service.
