Buying the best section 179 vehicles for your business comes with a meaningful tax upside, but how much you can deduct depends on what you buy, how heavy it is, and which deduction method you use. In 2026, the rules are more favorable than they have been in years. The One Big Beautiful Bill Act permanently restored 100 percent bonus depreciation and raised the Section 179 limit to $2,560,000, fundamentally changing the math on business vehicle deductions.
This guide explains how Section 179 and bonus depreciation apply to vehicles, which vehicles qualify for which limits, and how to combine both methods to maximize your first-year deduction.
How Section 179 Works for Vehicles
Section 179 allows businesses to deduct all or part of a qualifying vehicle’s cost in the year it is placed in service, rather than depreciating it over several years. The deduction requires that the vehicle be used more than 50 percent for business purposes. If business use falls at or below 50 percent, no Section 179 deduction is available.
When business use is between 51 and 99 percent, the deduction is prorated. A $50,000 vehicle used 70 percent for business produces a maximum Section 179 deduction of $35,000 based on that business-use percentage, subject to any applicable vehicle caps.
The overall Section 179 limit for 2026 is $2,560,000, with a phase-out beginning at $4,090,000 in total qualifying purchases and full elimination at $6,650,000. For most small and mid-size businesses, these thresholds are far beyond annual capital spending.
Section 179 cannot create a net operating loss. If the deduction would exceed your taxable business income for the year, the excess carries forward to future years. This is the primary reason some businesses prefer bonus depreciation for vehicle purchases.
How Bonus Depreciation Works for Vehicles
The OBBBA permanently restored 100 percent first-year bonus depreciation for qualifying property placed in service after January 19, 2025. Unlike Section 179, bonus depreciation has no annual dollar cap and can create a net operating loss that carries forward to offset income in future years.
For vehicles, bonus depreciation applies to the business-use portion of the cost. A $70,000 SUV used 80 percent for business has an $56,000 business-use basis. At 100 percent bonus depreciation, the full $56,000 is deductible in year one, subject to the luxury auto limits discussed below.
Crucially, the heavy SUV cap under Section 179 does not apply to bonus depreciation. This distinction is the key planning insight for business owners purchasing SUVs over 6,000 pounds GVWR.
Section 179 Applied First, Then Bonus Depreciation
The IRS requires Section 179 to be applied before bonus depreciation. For heavy SUVs, the combination works like this: apply the $32,000 Section 179 SUV cap first, then apply 100 percent bonus depreciation to the remaining cost basis.
A $90,000 heavy SUV used 100 percent for business produces a $32,000 Section 179 deduction, leaving $58,000 of remaining basis. Bonus depreciation then covers the full $58,000 in the same year. Total first-year deduction: $90,000. The SUV cap limits what Section 179 can do, but bonus depreciation closes the gap entirely.
Vehicle Categories and Deduction Limits
The IRS divides vehicles into three categories based on GVWR, each with different deduction limits.
Passenger Cars and Light Vehicles Under 6,000 Pounds GVWR
Vehicles with a GVWR of 6,000 pounds or less are subject to the luxury auto limits under IRC Section 280F. These limits cap how much depreciation can be claimed in each year of ownership regardless of the vehicle’s purchase price.
For vehicles placed in service in 2026 with bonus depreciation applied, the first-year limit is approximately $20,400. Without bonus depreciation elected, the first-year limit drops to approximately $12,400. Subsequent years face their own caps regardless of method. These limits apply to the business-use portion of the vehicle’s cost, not the full purchase price.
The luxury auto caps mean that even with 100 percent bonus depreciation, a $60,000 sedan used entirely for business can only generate a $20,400 first-year deduction. The remaining cost basis depreciates over the standard MACRS recovery period.
Heavy SUVs Between 6,001 and 14,000 Pounds GVWR
SUVs in this weight class are not subject to the luxury auto caps. Instead, Section 179 deductions for these vehicles are capped at $32,000 for 2026, up from $31,300 in 2025. As described above, bonus depreciation covers the remaining basis with no SUV cap applied.
A $120,000 luxury SUV in this category used 100 percent for business generates a $32,000 Section 179 deduction and $88,000 in bonus depreciation, for a total first-year deduction of $120,000. The same vehicle with 80 percent business use would apply these calculations to an $96,000 business-use basis.
GVWR determines which category a vehicle falls into, not curb weight. GVWR is the manufacturer’s rated maximum safe weight including passengers, cargo, and fuel. You can find it on the sticker inside the driver-side door jamb. A vehicle with a 5,900-pound curb weight may have a GVWR that places it above or below the 6,000-pound threshold depending on its rated capacity.
Trucks, Vans, and Other Vehicles Over 6,000 Pounds GVWR
Pickup trucks with a cargo bed at least six feet in length, cargo vans, and vehicles with a GVWR over 14,000 pounds are not subject to the Section 179 SUV cap. The full Section 179 deduction up to $2,560,000 applies, and 100 percent bonus depreciation covers any remaining basis.
A $55,000 pickup truck with a qualifying cargo bed used 100 percent for business can be fully deducted in year one through Section 179, bonus depreciation, or a combination.

2026 Ram ProMaster. Cargo van configuration with MSRP starting around $37,000. Full deduction available.
GVWR vs. Curb Weight: Why the Distinction Matters
When evaluating a vehicle for Section 179 purposes, GVWR is the determining factor, not curb weight. GVWR is the maximum rated weight of the vehicle including passengers, cargo, and fuel. Curb weight is the vehicle’s empty weight.
A vehicle with a 5,600-pound curb weight may have a GVWR of 6,200 pounds, placing it in the heavy SUV category rather than the luxury auto category. The difference between a $20,400 first-year deduction and a full $90,000-plus deduction can come down to that single number. Check the door sticker or manufacturer specifications before purchasing. The IRS Publication 946 provides detailed guidance on vehicle depreciation limits and categories.
Business Use Documentation
The IRS requires that business use be documented, not estimated. For any vehicle claimed under Section 179 or bonus depreciation, maintain a contemporaneous mileage log that records the date, destination, business purpose, and miles driven for each business trip.
If business use drops below 50 percent in a subsequent year, Section 179 and bonus depreciation already claimed must be partially recaptured as ordinary income. This is governed by the Section 1245 recapture rules, and the recapture amount is calculated on Form 4797.
The standard mileage rate for 2025 was 70 cents per mile. The 2026 rate had not been officially published at the time of writing. Alternatively, actual expenses prorated for business use, including fuel, insurance, maintenance, and depreciation, can be deducted in place of the mileage rate. You must choose a method and apply it consistently.
The Depreciation Recapture Risk
Fully expensing a vehicle through Section 179 or bonus depreciation reduces its adjusted basis to zero. When you eventually sell that vehicle for any amount above zero, the entire gain up to the original purchase price is subject to depreciation recapture as ordinary income under Section 1245. For a vehicle deducted at $90,000 and later sold for $40,000, the full $40,000 is ordinary income.
This does not make immediate expensing the wrong choice. The time value of money and current-year tax savings typically outweigh the future recapture cost. But planning around the eventual disposition of business vehicles is part of a complete depreciation strategy. See our guide on Section 179 vs. depreciation and amortization vs. depreciation for a broader look at how these decisions interact.
Closing Thoughts
2026 is one of the most favorable years on record for business vehicle deductions. Permanent 100 percent bonus depreciation combined with a $32,000 Section 179 SUV cap means that most heavy vehicles purchased for business can be fully expensed in the year of purchase, regardless of price. Pickup trucks and cargo vans with no SUV cap face even fewer constraints.
The planning decisions that matter are selecting a vehicle with a GVWR above 6,000 pounds when possible, documenting business use carefully throughout the year, and understanding the recapture implications before the vehicle is eventually sold.
Schedule a one-on-one strategy session to make sure your vehicle purchase is structured for maximum first-year deduction.
Frequently Asked Questions
What is the Section 179 deduction limit for vehicles in 2026?
The limits depend on vehicle type. Passenger cars and light vehicles under 6,000 pounds GVWR are subject to the luxury auto cap, which limits first-year depreciation to approximately $20,400 with bonus depreciation applied. Heavy SUVs between 6,001 and 14,000 pounds GVWR are capped at $32,000 under Section 179, but bonus depreciation covers the remaining basis at 100 percent with no additional cap. Pickup trucks with qualifying cargo beds, cargo vans, and vehicles over 14,000 pounds GVWR are not subject to any Section 179 vehicle cap.
What is the SUV cap for Section 179 in 2026?
The Section 179 deduction for heavy SUVs, those with a GVWR between 6,001 and 14,000 pounds, is capped at $32,000 for 2026. The remaining cost basis after the $32,000 Section 179 deduction can be fully expensed through 100 percent bonus depreciation in the same year, with no additional SUV cap applying.
What is the bonus depreciation rate for 2026?
100 percent. The OBBBA permanently restored 100 percent first-year bonus depreciation for qualifying property placed in service after January 19, 2025. This rate is no longer scheduled to phase down.
How do Section 179 and bonus depreciation work together for a vehicle?
Section 179 is applied first, up to its applicable limit. Bonus depreciation then covers the remaining cost basis. For a $90,000 heavy SUV used 100 percent for business, Section 179 covers $32,000 and bonus depreciation covers the remaining $58,000, producing a $90,000 total first-year deduction.
How do I determine my vehicle’s GVWR?
GVWR is printed on the sticker inside the driver-side door jamb. It represents the manufacturer’s maximum rated weight for the vehicle including passengers, cargo, and fuel. GVWR, not curb weight or actual weight, determines which Section 179 category the vehicle falls into.
What business use percentage is required for Section 179?
The vehicle must be used more than 50 percent for business purposes to qualify for any Section 179 deduction. The deduction is then prorated based on the actual business-use percentage. If business use falls to 50 percent or below in a subsequent year, previously claimed deductions must be partially recaptured.
Do electric vehicles qualify for Section 179?
Yes, provided they meet the applicable GVWR and business-use requirements. An electric SUV with a GVWR above 6,000 pounds qualifies for the $32,000 Section 179 cap plus bonus depreciation on the remainder, the same as any other heavy SUV. Additionally, some electric vehicles may qualify for the Section 30D clean vehicle credit separately from Section 179.
What happens when I sell a vehicle I fully expensed?
Selling a vehicle whose cost was fully deducted through Section 179 or bonus depreciation triggers depreciation recapture. The adjusted basis of a fully expensed vehicle is zero. Any sale proceeds up to the original purchase price are taxable as ordinary income under Section 1245, not capital gains rates. Planning the eventual disposition of business vehicles before purchase is an important part of the overall deduction strategy.
