What Section 179 covers and what it doesn't

Section 179 lets you deduct the full purchase price of certain business vehicles in the year you buy them, rather than spreading the deduction across several years. The catch is that not every vehicle qualifies — the IRS has specific rules about weight, use, and what counts as a business asset.

The most important rule: the vehicle must weigh more than 6,000 pounds. This is measured as the Gross Vehicle Weight Rating (GVWR), which you'll find on a sticker inside the driver's door frame or in the owner's manual. It's the maximum weight the vehicle can safely carry, not what it actually weighs. Most sedans, coupes, and small SUVs fall below this threshold and do not may have access to. Full-size pickup trucks, large SUVs, and commercial vans typically do.

The vehicle must also be used for business more than 50 percent of the time. Personal use — commuting to an office, weekend trips, or running errands unrelated to your business — doesn't count. You'll need to track mileage and document business use if the IRS ever asks.

Key Takeaways

  • The vehicle must have a Gross Vehicle Weight Rating (GVWR) over 6,000 pounds, which you can find on the door jamb sticker or in the owner's manual.
  • You must use the vehicle for business more than 50 percent of the time; personal use disqualifies it from Section 179.
  • Vehicles you lease do not may have access to for Section 179, but vehicles you purchase outright or finance do.
  • Trucks and large SUVs commonly may have access to, while most sedans and compact SUVs do not meet the weight requirement.
  • You can only claim Section 179 on vehicles placed in service during the tax year you're deducting them.

Vehicles that typically may have access to

Full-size pickup trucks almost always may have access to. A Ford F-150, Chevrolet Silverado, Ram 1500, and similar models have GVWRs well above 6,000 pounds. Even used models from recent years usually meet the threshold, though you should verify the specific year and trim level.

Large SUVs may have access to if they're built on a truck frame or are heavy enough. A Chevrolet Suburban, Ford Expedition, or GMC Yukon typically qualifies. Midsize SUVs like a Honda Pilot or Toyota Highlander often do not, because their GVWR falls below 6,000 pounds — check the door jamb sticker to be sure.

Commercial vans and cargo vans almost always may have access to. A Ford Transit, Mercedes Sprinter, or Chevrolet Express used for business purposes will have a GVWR above 6,000 pounds. Smaller passenger vans may not.

Vehicles you own outright or finance may have access to. Leased vehicles do not, because you don't own them. If you're considering a lease for business use, Section 179 is not available, though other deductions may be.

Vehicles that do not may have access to

Most sedans, coupes, and hatchbacks do not may have access to, regardless of price or how new they are. A luxury sedan or sports car, even if expensive, will have a GVWR under 6,000 pounds and will not meet the weight requirement.

Compact and midsize SUVs usually do not may have access to. A Honda CR-V, Toyota RAV4, Mazda CX-5, or Jeep Cherokee typically has a GVWR below 6,000 pounds. Some larger midsize SUVs are borderline — always check the door jamb sticker rather than guessing.

Motorcycles and ATVs do not may have access to, even if used entirely for business. Vehicles designed primarily for personal transportation, regardless of weight, fall outside Section 179 rules.

Any vehicle used for personal reasons more than 50 percent of the time is ineligible, even if it meets the weight requirement. If you use a may have access to truck for personal errands half the time, you cannot claim Section 179 on the full purchase price.

How to find the GVWR and verify qualification

The Gross Vehicle Weight Rating is printed on a label attached to the inside of the driver's door frame, usually on the edge of the door itself. It's a white or yellow sticker with vehicle specifications. Look for the line labeled "GVWR" or "Gross Vehicle Weight Rating" — the number will be in pounds.

If you can't find the sticker, check the owner's manual. The GVWR is always listed in the specifications section. You can also contact the dealership or manufacturer with the vehicle's year, make, model, and trim level, and they'll provide the GVWR.

For used vehicles, the GVWR doesn't change from year to year for the same model and trim. If you're shopping for a used truck or SUV, you can look up the GVWR online by entering the year, make, and model into a vehicle specification database, or ask the seller to show you the door jamb sticker.

Section 179 limits and phase-out rules

Even if your vehicle qualifies, there's a dollar limit on how much you can deduct in a single year. The limit changes annually and depends on when you place the vehicle in service. For 2024, the limit is $1,220,000, but this amount decreases each year as scheduled by law. Check the current year's IRS guidance or speak with a tax professional for the exact limit that applies to you.

If your total business asset purchases in a year exceed a certain threshold (also adjusted annually), your Section 179 deduction begins to phase out. This means you might not be able to deduct the full purchase price even if the vehicle qualifies. The phase-out threshold for 2024 is $4,880,000, but again, this changes yearly.

You can only claim Section 179 on a vehicle placed in service during the tax year you're deducting it. If you buy a truck in December 2024 and place it in service that same month, you can claim it on your 2024 return. If you buy it in January 2025, you claim it on your 2025 return.

Bonus depreciation as an alternative

If your vehicle qualifies for Section 179 but you can't use the full deduction because of the annual limit or phase-out rules, you may be able to use bonus depreciation instead. Bonus depreciation lets you deduct a percentage of the vehicle's cost in the first year, with the remainder spread across future years.

Bonus depreciation has its own rules and limits, and the percentage available changes based on tax law. For vehicles placed in service in 2024, bonus depreciation may allow you to deduct 60 percent of the cost in the first year. This is a complex area, and the rules vary depending on when the vehicle was manufactured and when you place it in service.

A tax professional or accountant can help you decide whether Section 179 or bonus depreciation makes more sense for your situation, especially if you're buying multiple vehicles or if your business income is high.

Frequently Asked Questions

Does a vehicle have to be brand new to may have access to for Section 179?

No. Used vehicles may have access to as long as they meet the weight requirement and are used for business more than 50 percent of the time. The GVWR doesn't change based on age, so a used truck that qualifies today may have access to when it was new.

Can I claim Section 179 on a vehicle I use for both business and personal reasons?

Only if business use is more than 50 percent. You can only deduct the portion of the cost that corresponds to business use. If you use the vehicle 70 percent for business and 30 percent personally, you can deduct 70 percent of the purchase price.

What if I buy a vehicle but don't place it in service until the following year?

You claim the deduction in the year you place it in service, not the year you purchase it. If you buy a truck in December 2024 but don't start using it for business until March 2025, you claim the deduction on your 2025 tax return.

Can I use Section 179 on a vehicle I lease?

No. Section 179 only applies to vehicles you own. If you lease a vehicle, you may be able to deduct lease payments as a business expense, but Section 179 is not available.

How do I know if my SUV weighs more than 6,000 pounds?

Check the Gross Vehicle Weight Rating on the sticker inside the driver's door frame. This is the maximum weight the vehicle can carry, not its actual weight. If the GVWR is above 6,000 pounds, it qualifies based on weight alone.
