6,000 lb Vehicle Tax Deduction: Section 179 SUVs in 2026

The 6,000 lb vehicle deduction refers to the extra tax write-off available for business SUVs, pickups and vans with a gross vehicle weight rating above 6,000 pounds. For 2026, Section 179 lets you expense up to $32,000 of a heavy SUV's business cost, and 100% bonus depreciation can generally cover the rest, so a vehicle used mostly for business can often be written off in its first year. Lighter cars face much lower annual depreciation caps.

This guide covers which vehicles qualify, the 2026 limits, how Section 179 and bonus depreciation combine, a worked example, and the traps: business-use tests, recapture, state rules and mileage logs. For the general comparison between the two write-offs, see Section 179 vs bonus depreciation; this article focuses only on vehicles. It is general information, not tax advice.

2026 vehicle limits at a glance

IRS Revenue Procedure 2025-32 sets the 2026 inflation-adjusted figures:

Limit	2026 figure
Overall Section 179 deduction limit	$2,560,000
Phase-out begins when Section 179 property placed in service exceeds	$4,090,000
Section 179 cap for SUVs over 6,000 lbs GVWR (up to 14,000 lbs)	$32,000
Bonus depreciation rate for qualified property acquired after January 19, 2025	100%

The 100% bonus rate was made permanent by the One Big Beautiful Bill Act in July 2025; see our One Big Beautiful Bill guide. Figures for 2027 will appear in the IRS revenue procedure for that year, usually released in the autumn.

Which vehicles qualify for the 6,000 lb deduction?

The test is the manufacturer's gross vehicle weight rating, the maximum loaded weight, shown on the label in the driver's door jamb. Curb weight does not count. The vehicle must also be placed in service in your business during the tax year and used more than 50% for business.

Vehicle type	Section 179 treatment	Bonus depreciation
Passenger car or light SUV, 6,000 lbs GVWR or less	Subject to annual luxury auto depreciation caps (around $20,000 in year one including bonus in recent years)	Included within the same caps
SUV over 6,000 lbs and up to 14,000 lbs GVWR	Capped at $32,000 for 2026	100% on remaining basis if acquired after Jan 19, 2025
Pickup with an interior cargo bed at least 6 feet long, not readily accessible from the passenger area	Not subject to the SUV cap	100%
Van with no seating behind the driver's seat and no body section protruding more than 30 inches ahead of the windshield	Not subject to the SUV cap	100%
Vehicle seating more than nine passengers behind the driver	Not subject to the SUV cap	100%
Over 14,000 lbs GVWR	Not an SUV for this cap; general Section 179 rules	100%

Do not rely solely on online lists of qualifying models. Trims of the same model can have different GVWRs, so check the specific vehicle's door sticker before you buy.

How Section 179 and bonus depreciation work together on a vehicle

The order matters. You apply the Section 179 election first, up to the $32,000 SUV cap and your business income limit, then bonus depreciation to the remaining business basis, then regular MACRS depreciation on anything left if you elect out of bonus. Section 179 cannot create a loss, while bonus depreciation can. That makes bonus alone a reasonable choice when profit is low, and Section 179 useful when you want to pick exactly how much to deduct. Both are claimed on Form 4562.

Worked example: a 6,400 lb SUV used 80% for business

The numbers are illustrative. A real estate photographer buys a new SUV in March 2026 for $78,000. Its door label shows a GVWR of 6,400 pounds. Her mileage log shows 80% business use. She expects $140,000 of net business profit.

Step	Amount
Purchase price	$78,000
Business-use basis (80%)	$62,400
Section 179 (capped at $32,000 for an SUV)	$32,000
Remaining business basis	$30,400
100% bonus depreciation on remainder	$30,400
Total first-year vehicle deduction	$62,400
Personal-use share (never deductible)	$15,600

At an assumed combined 22% income tax and the self-employment tax effect, the deduction saves well over $20,000 in 2026. Compare this to a 5,500 lb crossover at the same price, where the luxury auto caps would hold her first-year depreciation to a fraction of that amount. She also deducts 80% of fuel, insurance and repairs, plus the business share of any loan interest.

The catch: her later years have little depreciation left, and if she sells the SUV for $45,000 in 2029, much of the sale price is recaptured as ordinary income because her tax basis is near zero.

Business use: the rule that makes or breaks the deduction

Vehicles are listed property. To claim Section 179 or bonus depreciation, business use must exceed 50% in the year placed in service. If it later drops to 50% or less, you recapture the excess over straight-line depreciation. Commuting from home to a regular workplace is personal, not business. If your home is your principal place of business, trips to clients are generally business miles.

Keep a contemporaneous log of date, destination, purpose and miles for every business trip, or at least a representative sample period that reflects the whole year. Our mileage log template makes this easy.

Section 179 vs the standard mileage rate

Once you take Section 179 or bonus depreciation on a vehicle, you cannot use the standard mileage rate for that vehicle in later years. The IRS mileage rate for 2026 was 72.5 cents per mile from January to June and 76 cents from July 1, as explained in our IRS mileage rate 2026 guide. For high-mileage drivers with modestly priced vehicles, mileage can beat actual expenses over the life of the car. Run both scenarios using our comparison of standard mileage vs actual expenses before you decide.

Step by step: claiming the heavy vehicle deduction

1. Confirm GVWR from the door jamb label of the exact vehicle, and photograph it.
2. Keep the purchase documents: bill of sale, financing agreement and delivery date, which proves the placed-in-service date.
3. Start a mileage log on day one.
4. Choose your method with your preparer: Section 179, bonus, or both, considering business income and state rules.
5. Complete Form 4562, including Part V for listed property.
6. Track business use every year to avoid recapture.

Common mistakes with the 6,000 lb vehicle deduction

• Buying for the deduction alone. A deduction saves only your marginal tax rate on the cost. Spending $80,000 to save $25,000 still leaves you $55,000 poorer if you did not need the vehicle.
• Confusing curb weight and GVWR.
• Claiming 100% business use on the only family vehicle. Examiners routinely challenge this.
• Forgetting state differences. Several states do not follow federal bonus depreciation, and some cap Section 179 at lower amounts.
• Ignoring recapture on sale or trade-in. Plan for the tax when you dispose of the vehicle.
• Double-counting interest. Business loan interest goes on Schedule C; the separate personal car loan interest deduction applies only to personal-use vehicles.

Leasing, trading in and other edge cases

Leasing instead of buying

Section 179 and bonus depreciation apply only to vehicles you own. If you lease, you deduct the business share of lease payments over the lease term instead, and leased passenger vehicles may require an income inclusion amount that slightly reduces the deduction. Leasing spreads the deduction out rather than front-loading it.

Trading in an old business vehicle

Since 2018, a trade-in of a vehicle is treated as a sale of the old vehicle and a purchase of the new one, because like-kind exchanges now apply only to real property. The trade-in value is your sale price for the old vehicle, so if it was fully depreciated, you will have taxable gain, largely recaptured as ordinary income. The new vehicle's full price becomes its basis, which may support a larger deduction.

Vehicles owned by an S corporation or LLC

If the company owns the vehicle, it claims the depreciation, and your personal use is generally treated as a taxable fringe benefit or must be reimbursed to the company. If you own the vehicle personally and use it for your S corporation, the company can reimburse you for business miles under an accountable plan instead.

Already used the standard mileage rate?

If you used the standard mileage rate in the first year a vehicle was used for business, you can switch to actual expenses later, but you must use straight-line depreciation for the rest of the vehicle's life. Section 179 and bonus are no longer available for that vehicle.

Two vehicles, one business

Owners with a family car and a work truck often get the best result by keeping the heavy vehicle almost entirely for business and using the other car for personal trips. A clean split makes the business-use percentage easy to prove, keeps you safely above the 50% test and avoids arguments over mixed-use trips. Write the arrangement down at the start of the year and let the mileage log back it up.

Paying for the vehicle

Because the deduction does not depend on paying cash, many owners finance the purchase. Compare dealer financing with options in our guide to equipment financing, and remember the tax saving arrives when you file, not when you buy.
