Several 2026 Toyotas qualify for the Toyota Section 179 tax deduction, including the Tundra, Sequoia, Land Cruiser, 4Runner, and certain configurations of the Tacoma and Grand Highlander. The dividing line is a gross vehicle weight rating above 6,000 pounds. Clearing that threshold moves a vehicle out of the luxury-auto depreciation limits and into territory where a business can write off either $32,000 or the entire purchase price in year one, depending on how the IRS classifies the body style.
Toyota Models That Clear the 6,000-Pound Threshold
GVWR is the manufacturer’s maximum operating weight, printed on the sticker inside the driver’s door jamb. It doesn’t change with how much you’re hauling, and no option package will push a vehicle’s rating above what the manufacturer sets. Ratings shift between model years and trims, so confirm the sticker on the specific vehicle you’re buying.
Toyota Tundra
Every Tundra configuration clears the threshold comfortably, with GVWRs generally ranging from roughly 6,800 to over 7,200 pounds depending on cab style and drivetrain. The Tundra is also the one Toyota that can escape the $32,000 heavy-SUV cap entirely, because it’s a pickup. More on that below.
Toyota Sequoia
The 2026 Sequoia carries a GVWR of approximately 7,560 pounds across the lineup.1Edmunds. 2026 Toyota Sequoia SUV Specs and Features It’s classified as a heavy SUV, so the $32,000 Section 179 cap applies, with bonus depreciation available on the remainder.
Toyota Land Cruiser
The reintroduced Land Cruiser has a GVWR of approximately 6,725 pounds.2Car and Driver. Toyota Land Cruiser Features and Specs Like the Sequoia, it’s a heavy SUV subject to the $32,000 cap.
Toyota 4Runner
The redesigned 2026 4Runner comes in at approximately 6,075 pounds GVWR.3Edmunds. 2026 Toyota 4Runner Specs and Features That’s only 75 pounds of margin. Certain lighter trim configurations could potentially fall below 6,000 pounds, so checking the sticker is essential.
Tacoma and Grand Highlander: Check the Configuration
The 2026 Tacoma hits approximately 6,005 pounds GVWR in its SR5 Double Cab 4WD trim.4Edmunds. 2026 Toyota Tacoma Specs and Features Five pounds over the line. Lighter Tacoma trims, particularly two-wheel-drive versions with smaller cabs, may fall below. The 2026 Grand Highlander comes in at roughly 6,030 pounds for certain configurations.5Edmunds. 2026 Toyota Grand Highlander Specs and Features Lighter trims of either model may not qualify.
Models That Don’t Qualify
The standard Highlander, RAV4, Corolla Cross, and other smaller Toyotas all sit below 6,000 pounds and are capped at the luxury-auto first-year limit of $20,300 for 2026, with bonus depreciation included.
Why Tundras Can Get a Bigger Write-Off Than Sequoias
The $32,000 Section 179 cap applies specifically to sport utility vehicles. Pickup trucks with a cargo bed at least six feet long are not SUVs under the IRS definition, even when they weigh the same. A qualifying pickup can deduct up to the full $2,560,000 general Section 179 limit, which for a single-vehicle buyer means the entire cost of the truck.6Internal Revenue Service. Rev. Proc. 2025-32
Bed length is where this gets specific. The Tundra Double Cab offers a 6.5-foot bed and clears the requirement. The CrewMax comes with either a 5.5-foot or 6.5-foot bed, so a short-bed CrewMax falls back into heavy-SUV territory and the $32,000 cap, while the long-bed CrewMax does not. Two nearly identical Tundras on the same lot can carry very different tax treatment based on bed alone.
The Tacoma’s standard bed is five feet and its long bed is six feet. Only Tacoma configurations clearing both the 6,000-pound GVWR and the six-foot bed requirement avoid the SUV cap. Most Tacoma buyers will land in the heavy-SUV bucket, limited to $32,000 under Section 179 but still eligible for bonus depreciation on the balance.
What You Can Actually Deduct in 2026
For tax years beginning in 2026, the overall Section 179 limit is $2,560,000, phasing out dollar-for-dollar once total qualifying equipment purchases exceed $4,090,000.6Internal Revenue Service. Rev. Proc. 2025-32 Those ceilings rarely affect a business buying a single vehicle. The number that matters for most Toyota buyers is the $32,000 heavy-SUV cap.
Anything left over after Section 179 can be written off through 100% bonus depreciation, which was made permanent by the One, Big, Beautiful Bill for property acquired after January 19, 2025.7Internal Revenue Service. Treasury, IRS Issue Guidance on the Additional First Year Depreciation Deduction Amended as Part of the One, Big, Beautiful Bill Stacked together, Section 179 and bonus depreciation let qualifying heavy vehicles be fully expensed in year one.
Example: Heavy SUV (Sequoia at $80,000, 100% Business Use)
Section 179 covers $32,000. The remaining $48,000 qualifies for 100% bonus depreciation. First-year deduction: $80,000.
Example: Long-Bed Tundra at $65,000, 100% Business Use
Because the bed is at least six feet long, the SUV cap doesn’t apply. The business can elect to expense the full $65,000 under Section 179 alone.
Example: Sequoia With 80% Business Use
Deductible basis is $64,000 (80% of $80,000). The business claims $32,000 under Section 179, then applies 100% bonus depreciation to the remaining $32,000 of deductible basis. First-year deduction: $64,000.
One limit on Section 179 itself: it can reduce taxable business income to zero but cannot create a loss. If your business earns $40,000 before the deduction, your Section 179 deduction is capped at $40,000 that year, with the unused portion carried forward.8Internal Revenue Service. Publication 946 (2025), How To Depreciate Property Bonus depreciation has no such limit and can generate a net operating loss.
Business Use, Mileage Logs, and Recapture
The vehicle must be used for business more than 50% of the time. This is a hard cutoff: 50% or less means no Section 179 at all, not a reduced deduction.8Internal Revenue Service. Publication 946 (2025), How To Depreciate Property Once past 50%, the deduction scales to your actual business-use percentage.
The IRS expects contemporaneous mileage records: date, destination, business purpose, and miles driven, logged as trips happen rather than reconstructed at tax time. Vehicle deductions are a trained area of audit scrutiny, so a mileage app or equivalent log is not optional.
If business use drops to 50% or below in any year after you claim the deduction, you owe recapture tax. The IRS calculates what depreciation would have been under the standard method, compares it to what you took, and taxes the difference as ordinary income. On a $75,000 vehicle, recapture can easily exceed $20,000. The rule applies for the vehicle’s full depreciable life, which is six years for trucks and SUVs classified as five-year property.
Used, Financed, and Leased Vehicles
Used Toyotas qualify as long as the vehicle is new to your business and acquired by purchase. A two-year-old Tundra from a dealership works; a vehicle you already owned personally and started using for business does not.8Internal Revenue Service. Publication 946 (2025), How To Depreciate Property
Financing doesn’t reduce the deduction. $5,000 down and $70,000 financed on a qualifying Sequoia still produces a $75,000 deduction in year one. The IRS treats a financed purchase the same as a cash purchase for both Section 179 and bonus depreciation.
Leases are different. Only the owner depreciates the vehicle, and that’s usually the leasing company. If you lease, your tax benefit comes through the lease payment deduction under Section 162, not Section 179.
Claiming the Deduction on Form 4562
Section 179 and bonus depreciation are reported on IRS Form 4562, filed with your business tax return for the year the vehicle is placed in service.9Internal Revenue Service. Instructions for Form 4562 (2025) “Placed in service” means the date you start using the vehicle for business, not the purchase date. Buy in December, start using in January, and it belongs on the following year’s return.
The Section 179 election goes in Part I: property description, cost, and amount elected. Bonus depreciation on the remaining basis goes in Part II. The vehicle also appears in Part V (Listed Property), where you document business-use percentage, total miles, and business miles. Those figures need to match your mileage logs exactly.10Internal Revenue Service. Form 4562, Depreciation and Amortization (Including Information on Listed Property)
The vehicle must be placed in service by December 31 to claim the deduction for that tax year. There’s no proration under Section 179 or bonus depreciation, so a vehicle placed in service on December 30 produces the same first-year deduction as one placed in service on January 2.
State Taxes May Not Follow Federal Rules
All of the limits above are federal. Some states cap Section 179 at a lower amount, require the deduction to be spread over multiple years, or don’t conform at all. A vehicle generating a full federal write-off can produce a much smaller state deduction, which means owing state tax on income you’ve already erased federally. Check your state’s treatment with a tax professional before counting the full deduction against your combined tax bill.
