Vehicles Over 6,000 Pounds That Qualify for Tax Deductions

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 and placed in service 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.

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.

One nameplate on this list gets its own page because it gets its own search traffic and its own mythology: the Mercedes G-Class. If that is the vehicle you are actually researching, read the G-Wagon tax write-off guide for the model-specific math, including the recapture scenario nobody posts about.

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. That ceiling exists because Congress got annoyed at the original "SUV loophole" two decades ago and trimmed it, without touching bonus depreciation.

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.

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.

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. The IRS wrote this rule for exactly one fact pattern: big deduction in year one, driveway ornament by year three.

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. Heavy SUVs hold value well, which is great for your garage and bad for your recapture bill. 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. 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.

4. A deduction is not a coupon.

Spending $95,000 to save roughly $24,000 of tax still costs you about $71,000. If the business needs the truck, the deduction makes a necessary purchase cheaper. If the business does not need it, you have bought an expensive vehicle and a smaller bank balance, plus a recapture liability. Buy the vehicle the business needs; take the deduction the law allows; never reverse the order.
