The Answer, First

If you buy a truck, SUV, or van with a gross vehicle weight rating over 6,000 pounds and use it more than 50% for business, current federal law lets you deduct the business-use portion of the price in year one through 100% bonus depreciation. The weight rating is on the sticker inside the driver's door. The deduction is real, it is legal, and the documentation requirements are where most people blow it.

Before you read another word, go do one thing. Walk to your vehicle, open the driver's door, and read the sticker on the door jamb. Find the line that says GVWR. If that number is over 6,000 pounds, this page is about to get very interesting. If you are shopping for a vehicle, keep reading anyway, because in ten minutes you will shop differently.

Meet Anthony. He built his own company out of his garage, a promotional products business that now has a warehouse, four employees, and a very good year behind it. His accountant has been quietly wincing at his tax bill the whole way up. In November, Anthony buys a Chevy Suburban for $92,000. He checks the sticker inside the driver's door: GVWR 7,500 pounds. Over the line.

Anthony uses the Suburban 80% for business. Supplier pickups, client deliveries, trade shows, hauling samples and displays. He keeps a mileage log, because Anthony read this page first.

Here is his math. $92,000 price. 80% business use. $73,600 of business basis. Under current law, 100% bonus depreciation lets him deduct the whole $73,600 in year one. At a 37% federal rate, that is roughly $27,000 of tax he does not send to Washington this year.

Same truck. Same driveway. One family reads the instruction manual and one does not.
Two neighbors buy the same $92,000 Suburban
Anthony reads the sticker, keeps a simple mileage log, and writes off $73,600 of his truck this year. His tax bill drops by about $27,000.
Dave drives the same truck for his business, keeps no log, and claims nothing. His tax savings: $0.

It works pre-owned, too

Rosa runs a tile business, and she does not buy new trucks on principle. In March she picks up a three-year-old F-250 for $58,000 from a dealer. GVWR: 9,900 pounds, not even close to the line. The truck is 100% business: job sites, material runs, towing the trailer. Because the truck is new to Rosa, bought from an unrelated party, used vehicles qualify for the same 100% bonus depreciation. Her year-one deduction is the full $58,000, roughly $18,500 of tax saved at her bracket. Rosa got the same tax treatment as Anthony, on a truck that already had its first ding.

The realtor's version

Nicole sells real estate, the profession that practically lives inside this deduction. Like most agents she is 1099 self-employed, and her Tahoe, 7,400 pounds on the sticker, is her real office: buyer tours, listing appointments, broker caravans, open house setups, sign and lockbox runs. At 85% business use on a $78,000 Tahoe, her year-one bonus deduction is $66,300, roughly $22,000 saved at her bracket. Her log reads like Anthony's, just with addresses instead of orders. One warning for her salaried colleagues: W-2 employees cannot deduct vehicle expenses under current law. This break belongs to the self-employed, which happens to be most of the profession.

Vehicles that commonly clear the line

Approximate GVWR ranges by category, recent model years. The ranges move with trim, drivetrain, and year, so treat this as your shopping list, not your proof. Only the sticker on the actual vehicle gets you the deduction.

Full-size SUVs

Luxury and import SUVs

Pickups

Electric vehicles

Batteries are heavy, and heavy is exactly what this rule rewards. A surprising number of EVs clear the line with room to spare:

Work vans

Borderline: the sticker decides

Why 6,000 pounds?

Congress capped depreciation on regular passenger cars decades ago so executives could not write off luxury sedans. But work vehicles needed an exception, so vehicles over 6,000 pounds GVWR escaped the caps. Automakers noticed. That is why half the SUVs on the road today sit just above the line.

The rules in plain English

  1. GVWR over 6,000 pounds. Not curb weight. The rating on the door sticker.
  2. More than 50% business use, measured by miles. Drop below 50% later and the IRS claws part of the deduction back. That is called recapture, and it is not a surprise you want.
  3. The deduction applies to the business-use percentage only.
  4. Placed in service by December 31 of the tax year. Sitting at the dealer does not count. Driving it for the business does.
  5. A mileage log is not optional. Date, destination, purpose, miles. Contemporaneous, kept as you go. Courts throw out logs rebuilt from memory in April.

Heavy pickup trucks with a full-size bed have their own even friendlier lane under Section 179, and certain vans qualify too. Dollar limits on the Section 179 SUV path adjust every year, which is exactly the kind of detail your CPA confirms at filing time. The bonus depreciation path has no such cap for qualifying heavy vehicles.

What about buying a new truck every year or two?

Anthony's brother-in-law Vince trades trucks the way some people trade phones. His theory: new Suburban every other year, new $70,000 write-off every other year, free money forever. Vince has not met recapture yet.

Here is what actually happens. Each new qualifying vehicle does earn its own year-one deduction, so yes, a buyer can take the write-off again on the next truck. But the old truck does not just vanish from the tax return. When Vince sells it or trades it in, the IRS treats that as a sale, and because the truck was already fully written off, nearly every business-use dollar he gets for it comes back as taxable income. Deduct $73,600 going in, sell the truck two years later for $58,000, and roughly the business share of that $58,000 lands right back on his return the year he sells.

So the every-two-years plan is not a money machine. It is a revolving door: a big deduction walking in, most of it walking back out as recapture, and only the value the truck actually lost staying deducted for good. That is how Congress designed it. The write-off is a timing tool, and timing is worth real money, because dollars deducted against a big income year beat dollars scattered across a decade. But the owners who win biggest buy the truck, run it hard for years, and let the deduction stay where it landed.

One wrinkle worth knowing before you visit the dealer: vehicle trade-ins stopped being tax-free swaps in 2018. A trade-in is a sale in the eyes of the IRS, even when no cash touches your hands. Your CPA runs the exact numbers before you sign anything.

What a defensible log actually looks like

Five real lines are worth a page of theory. Anthony's, kept the day each trip happened:

From Anthony's log · promotional products company
Feb 6 · Warehouse to Apex Supply and back · picked up blank apparel for the Coleman order · 41 miles
Feb 12 · Office to First National, then Old Town Print · deposit and proof approval · 18 miles
Feb 19 · Office to Charlotte trade show · booth setup, samples and displays · 96 miles
Mar 3 · Office to Hartline Logistics · delivered the 400-piece order · 52 miles
Mar 9 · Office to equipment shop · heat press pickup after repair · 27 miles

Then there is Grace, because half the people reading this run their company from a spare bedroom. Grace owns an online home decor business, and her home office qualifies as her principal place of business: exclusive, regular, and where the work actually happens. That one fact upgrades her mileage, because when your home office is your principal place of business, trips from home to business stops are business miles, not commuting. Her Tahoe reads 7,400 pounds on the sticker.

From Grace's log · home-based home decor company
Feb 3 · Home office to USPS bulk center · shipped 62 customer orders · 14 miles
Feb 10 · Home office to supplier warehouse · picked up candle and vase inventory · 38 miles
Feb 17 · Home office to storage unit · rotated seasonal stock · 11 miles
Feb 24 · Home office to photoshoot rental · product photography day · 29 miles
Mar 2 · Home office to vendor market, booth 14 · weekend market selling · 46 miles

Date, route, business purpose, miles. Thirty seconds per trip, logged the day of the trip. That habit is the difference between a deduction and a donation.

The mistakes that get people in trouble

Questions owners actually ask

How do I find my vehicle's GVWR?
Open the driver's door and read the manufacturer's sticker on the door jamb. GVWR is listed in pounds. It is the rating, not what the vehicle actually weighs.
Does a lease qualify?
Leases follow different rules; you generally deduct the business portion of lease payments rather than depreciation. Buying, including financed purchases, is what unlocks the year-one write-off. Ask your CPA which fits your situation.
Can I use the vehicle personally at all?
Yes. You deduct only the business-use percentage, and it must stay above 50% to keep the accelerated treatment. Track it with a mileage log.
I'm buying a pre-owned vehicle over 6,000 pounds this year. Does it still qualify?
Yes. Bonus depreciation applies to used vehicles as long as the vehicle is new to you: you bought it from an unrelated party and had not been using it before the purchase (buying out the lease on the truck you already drive follows different rules). Same weight test, same over-50% business use, same mileage log. A well-chosen pre-owned Suburban earns the same year-one write-off as a new one, on a smaller price.
Is this the same as Section 179?
They are cousins. Section 179 and bonus depreciation can both accelerate vehicle deductions, with different limits and rules. Under current law, 100% bonus depreciation is usually the simpler path for heavy vehicles. Your CPA picks the right tool at filing.
The Catch

Three ways this deduction bites back. Sell or trade the truck and recapture brings the write-off home as income. Let business use slip under 50% and the IRS claws back the acceleration. Skip the mileage log and none of it survives a second look. The strategy is real; the discipline is the price.

Your four moves before December 31

  1. Read the sticker. GVWR over 6,000 pounds, on the vehicle you are actually buying.
  2. Be honest about business use. Over 50% by miles, and plan to keep it there.
  3. Start the log the day you take delivery. Not in April.
  4. Place it in service: real business driving before year end, then tell your CPA it is ready for the return.
The Bigger Play

A $27,000 truck deduction is a good day. The building your business sits in is hiding ten of those. Most owners are sitting on $200,000 to $450,000 per million in unclaimed deductions inside the walls, the systems, and the parking lot of their own property. You found the money in the driveway. Now send the engineers inside.
