Section 179 Vehicles 2026: SUVs and Trucks Over 6,000 lbs GVWR

The tax code caps how fast a "passenger automobile" can be depreciated, no matter what it cost. For a car placed in service in 2026, the first-year deduction tops out at $20,300 with bonus depreciation ($12,300 without it), then $19,800 in year two, $11,900 in year three, and $7,160 a year after that. On a $70,000 sedan, that schedule stretches the write-off well past a decade.

Those caps only apply to vehicles the code defines as passenger automobiles, and that definition excludes trucks, vans, and SUVs rated above 6,000 pounds gross vehicle weight. Cross the rating and the vehicle is treated like ordinary business equipment: eligible for Section 179 expensing and for bonus depreciation with no annual dollar ceiling on the bonus piece.

Timing matters here. The One Big Beautiful Bill Act made 100% bonus depreciation permanent for qualified property acquired after January 19, 2025. Under prior law the percentage was phasing down; that phase-down is gone. For heavy vehicles bought and placed in service now, full first-year expensing of the business-use share is the default math, not a limited-time window.

Two conditions carry all the weight. First, business use must exceed 50% of total miles to use Section 179 or bonus depreciation at all. Second, only the business-use percentage is deductible. An 80% business-use vehicle deducts 80% of its cost, never 100%. The general rules, including the mileage-vs-actual method choice and the substantiation requirements, live on our business vehicle deduction guide; this page owns the list.

A pickup with a GVWR above 6,000 pounds escapes the luxury auto caps just as a heavy SUV does. Section 179 then turns on the bed. An open cargo area at least six feet long inside, not readily accessible from the cab, takes the truck out of the SUV definition, so the $32,000 SUV limit for 2026 does not apply.

A long-bed truck can use the general Section 179 limit of $2,560,000 for 2026, which starts to phase out once total Section 179 purchases pass $4,090,000. A short-bed crew cab stays under the $32,000 limit. Either way, 100% bonus depreciation has no SUV cap, so check the bed length on the exact trim in the pickup list above and keep business use above 50%.

The deduction lands in the year the vehicle is placed in service, meaning delivered and ready for business use, not the year you sign or pay. For a calendar-year business, a vehicle has to be in your hands and ready to work by December 31, 2026 to count on the 2026 return. A truck ordered in December that arrives in January is a 2027 deduction.

The 100% bonus depreciation rate covers vehicles acquired after January 19, 2025, so the rate is not the deadline. Delivery is. Business use also has to be more than 50% in the year you claim the deduction, and your mileage log should start the day the vehicle arrives.

• Take delivery before December 31. A signed contract or a deposit is not enough.
• Keep the purchase contract, the delivery date, and a photo of the door-jamb sticker.
• Start the mileage log on day one and keep it all year.
• Check the cash. Paying for a vehicle to cut tax still leaves most of the price out of pocket.

GVWR is the maximum loaded weight the manufacturer rates the vehicle for: vehicle plus passengers plus cargo. Curb weight is what it weighs empty. The tax test runs on the rating, which is why a Model X that curbs around 5,400 pounds still clears the threshold: its GVWR is roughly 6,250.

The same nameplate can land on both sides of the line. A BMW X5 or Porsche Cayenne clears 6,000 pounds in some trims and misses in others. A Honda Odyssey posts a GVWR between roughly 5,935 and 6,019 pounds depending on trim, which means most Odysseys do not qualify, and the ones that do only prove it on the sticker.

Every vehicle below is commonly rated above 6,000 pounds GVWR in recent model years, except the last group, which is on the list precisely because people assume it qualifies and it usually does not. GVWR varies by trim and model year, so treat these numbers as a starting point and verify the door-jamb sticker before purchase. The short list at the top splits out SUVs, pickups, and EVs; this version adds cargo vans and lets you search.

SUVs Over 6,000 lbs, Plus the Trucks and Vans

Use the filter buttons to see just the SUVs over 6,000 pounds (the largest group, from the Tahoe and Expedition to the G-Class), the pickups where bed length changes the Section 179 treatment, or the cargo vans that skip the SUV cap entirely.

If you are considering a Mercedes G-Class, the G-Wagon tax write-off guide takes that model through a purchase and sale example, including depreciation recapture. It is a useful next step once you have confirmed the vehicle's rating.

Heavy SUVs (GVWR between 6,001 and 14,000 pounds) carry a special Section 179 ceiling: $31,300 for tax years beginning in 2025, $32,000 for 2026. Section 179 and bonus depreciation have separate rules, so the SUV ceiling is only one part of the calculation.

The cap has carve-outs. A pickup with a cargo bed of at least six feet of interior length, a van seating nine or more behind the driver, or a cargo van with no seating behind the driver's row is not an "SUV" for this rule, and gets the full Section 179 limit instead. That is why an F-250 long bed or a Sprinter cargo van can be expensed under 179 without the $32,000 ceiling, while a crew-cab short-bed F-150 cannot.

Here is the practical punchline: with 100% bonus depreciation permanent, the SUV cap rarely matters. Bonus has no per-vehicle dollar limit, applies to new and used vehicles alike, and can create or deepen a business loss, which Section 179 cannot (179 is limited to business income, with the excess carried forward, under an overall limit of $2.5 million for 2025 and $2.56 million for 2026). Most heavy-vehicle buyers today simply take bonus on the business-use share and move on.

The finer points of bonus depreciation, including placed-in-service timing, the election out by asset class, and state conformity headaches, are covered in our bonus depreciation guide. State add-backs matter more than people expect: several states do not follow federal bonus rules, so the state deduction can lag the federal one by years. If you are timing a purchase around year-end, the 2026 tax deadlines calendar shows every date that matters.

A deduction this size usually collides with the rest of the tax picture: it can drop a quarterly estimate, change an S corp owner's salary math, or swing a safe-harbor calculation. If you take a large vehicle write-off mid-year, recheck your estimated tax payments before the next quarterly due date, and if you run an S corp, run the S corp savings calculator with the new deduction in the numbers. If you would rather run it with a firm, see how our S corp CPA and small business CPA services work.

1. Business use drops below 50% and the deduction comes back.

A vehicle is listed property. If business use falls to 50% or below in any year of the recovery period, the law recomputes what straight-line depreciation would have allowed and adds the excess you deducted back into your income that year, then forces slower straight-line treatment going forward. Keep tracking business use after the first year so a change can be identified and reported.

2. Depreciation recapture on sale turns the gain ordinary.

Fully expensing a vehicle sets its tax basis to zero. Sell it later and the gain, up to the depreciation you took, is ordinary income, not capital gain. The sale price therefore matters when you compare the cost of ownership. The write-off is a timing benefit that partially unwinds at sale; model both ends before you count the savings.

3. Standard mileage might beat actual expenses anyway.

The 2026 standard mileage rate is 72.5 cents per mile for January through June and 76 cents from July 1 (the IRS raised it mid-year). A high-mileage, modest-cost vehicle can out-deduct the actual-expense method over its life with far less recordkeeping. And the fork is mostly one-way: take Section 179 or bonus on a vehicle and you cannot switch that vehicle to the standard mileage rate later. And if the vehicle is mostly personal, business depreciation is off the table entirely, but the new car loan interest deduction may apply to a personal-use vehicle through 2028.

4. Consider what the purchase still costs.

In the example above, spending $95,000 to reduce tax by roughly $24,000 still leaves an outlay of about $71,000 before future sale proceeds and tax effects. The business needs to be able to afford that purchase. Compare suitable vehicles on price, running costs, and expected use, then include the tax treatment in the decision.
