IRS Section 179 Vehicle Deduction List: Vehicles Over 6,000 Pounds

You're about to buy a heavy-duty pickup or a full-size SUV for your business, and you've heard that you might be able to write off the entire purchase this year. That might sound too good to be true, but it's not. The Section 179 vehicle deduction list covers a wide range of trucks, vans, and SUVs with a gross vehicle weight rating (GVWR) exceeding 6,000 pounds. For many business owners, this deduction can significantly reduce taxable income in the year the vehicle is placed in service.

Use this guide to understand what vehicles qualify for the Section 179 deduction, its limitations, and what your business needs to do to ensure the deduction is claimed correctly.

Key Takeaways

• Vehicles are qualified based on GVWR, not curb weight. Your vehicle must have a GVWR over 6,000 pounds to qualify for Section 179 treatment.

• SUVs with a GVWR between 6,001 and 14,000 pounds are subject to a separate $31,300 heavy SUV deduction cap for 2026.

• Trucks and cargo vans over 6,000 pounds that are not classified as SUVs may qualify for the full Section 179 deduction.

• The vehicle must be used more than 50% of the time for business purposes.

• Section 179 and bonus depreciation are separate tools that can sometimes be combined for the same vehicle.

• Accurate mileage logs and purchase records are required to substantiate the deduction.

• If business use drops below 50% in a later year, the IRS may require you to repay a portion of the deduction as income under depreciation recapture rules.

• For a broader look at how the deduction works across all asset types, this Section 179 overview is a great starting point.

What Is the Section 179 Vehicle Deduction?

Section 179 allows small businesses to deduct the cost of qualifying property, including eligible vehicles, in the year the asset is placed in service, rather than depreciating it over time. The front-loaded deduction is the main appeal: instead of recovering a fraction of the cost each year, you can reduce your taxable income significantly in year one.

Section 179 is a tax deduction, not a credit. Deductions reduce your taxable income and lower your tax liability, while a credit reduces your tax bill dollar-for-dollar. The practical difference matters. A $30,000 deduction at a 25% effective rate saves you $7,500, not $30,000.

The vehicle doesn't have to be paid in full to qualify. If you finance the purchase, the full cost can still qualify for the deduction as long as the vehicle is placed in service during the tax year.

The 6,000-Pound Rule: What GVWR Means and Why It Matters

Eligibility isn't determined by a vehicle's actual weight or its curb weight. Instead, it uses the gross vehicle weight rating, or GVWR. GVWR is the maximum operating weight of the vehicle as specified by the manufacturer, which includes:

• The vehicle itself

• Passengers

• Cargo

• Fuel

Always verify the spec before you buy. A vehicle that looks mid-size on the lot might have a GVWR over 6,000 pounds, while a vehicle that appears larger could fall just under the cutoff. You can't eyeball it. To find the official GVWR, check the sticker inside the door jamb, typically on the driver's side. You can also find it in the manufacturer's spec sheet or window sticker.

Using curb weight rather than GVWR to qualify a vehicle is a mistake that can result in a disallowed deduction. The IRS guidance on business use of vehicles makes clear that GVWR is the relevant standard.

Section 179 Vehicle Deduction List: Vehicles Over 6,000 Pounds

No single IRS list exists for qualifying vehicles. GVWR can vary by trim level and model year, so the table below reflects commonly qualifying vehicles based on typical ranges. Always confirm the specific GVWR for the exact make, model, trim, and year before purchasing.

There are two categories of qualifying vehicles, and they're treated differently:

• Heavy SUVs (GVWR 6,001–14,000 lbs): These qualify for Section 179 but are subject to a separate deduction cap ($31,300 for 2026).

• Non-SUV vehicles over 6,000 lbs (trucks, cargo vans, full-size vans): These are not subject to the SUV cap and may qualify for the full Section 179 deduction amount.

An SUV is defined as any four-wheeled vehicle primarily designed for passenger transport on public streets with a GVWR between 6,001 and 14,000 pounds. Trucks and vans designed primarily for cargo transport fall outside that definition and are not subject to the SUV cap.

Deduction Limits and Caps to Know

For 2026, the Section 179 deduction limit is $2,560,000, with a phase-out threshold of $4,090,000. Once your total equipment and vehicle purchases for the year exceed that threshold, the deduction reduces dollar-for-dollar. You can find figures for preparing 2025 returns in Publication 946, which governs IRS vehicle depreciation rules.

A hard cap applies to SUVs regardless of purchase price: $31,300 for 2026. If you buy a $75,000 SUV and use it exclusively for business, your Section 179 deduction is still limited to $31,300. The remaining cost basis can potentially be recovered through bonus depreciation or regular depreciation, but not through Section 179 alone.

The Section 179 deduction cannot exceed your business's taxable income for the year. If your deduction would create a loss, the excess carries forward to future years.

Section 179 deduction limits interact with bonus depreciation in ways that can significantly affect your overall tax saving strategies. Working with a 1-800Accountant tax advisor year-round helps you plan vehicle purchases at the right time and structure deductions to maximize the benefit.

Business Use Requirements and the 50% Rule

Section 179 only applies to the business-use portion of a vehicle. If you also use it personally, you can deduct only the percentage attributable to business use, as long as it doesn't fall below the threshold.

The vehicle must be used more than 50% for business purposes to qualify for Section 179. If business use is exactly 50% or less, you'd have to depreciate the vehicle under the Alternative Depreciation System (ADS), which is slower and less favorable to business owners.

For mixed-use vehicles, the math is straightforward. If you use a qualifying truck 70% for business, only 70% of the purchase price is eligible for the deduction.

If your business use drops below 50% in a later year after you've already claimed the deduction, you may be subject to recapture. The IRS can require you to repay a portion of the deduction as ordinary income. This has caught many business owners off guard.

Keeping a mileage log is the most reliable way to document your business-use percentage. For more on vehicle tax deductions, including when the standard mileage rate method might work better than tracking actual expenses, refer to these guides.

A tax professional can help you calculate the correct business-use percentage and flag recapture risks before they ever become a problem. This is exactly where 1-800Accountant's tax advisory solution can make a difference, particularly for owners who use the same vehicle for work and personal use.

Section 179 vs. Bonus Depreciation: What's the Difference?

Many business owners have heard of Section 179 and bonus depreciation but aren't sure which one to use, or whether they need to choose at all. They're different tools, and in some cases, you can use both on the same vehicle.

Section 179 is elective, capped, and limited by your business's taxable income. Bonus depreciation allows you to deduct a set percentage of a qualifying asset's cost immediately. Unlike Section 179, it's not limited by taxable income, which means bonus depreciation can create a business loss. For 2026, the bonus depreciation rate is 100%.

The typical approach for a qualifying vehicle is to apply Section 179 first, then use bonus depreciation on any remaining cost basis. For a closer look at bonus depreciation and how the current phasedown schedule affects your planning, this article goes deeper into the mechanics.

Recordkeeping Requirements

The IRS expects specific documentation to support a vehicle deduction. Poor recordkeeping is one of the most common reasons vehicle deductions are disallowed. Not the deduction itself, but the inability to prove it.

Here's what you need to keep:

• A mileage log showing the date, destination, business purpose, and miles driven for each business trip

• The vehicle purchase receipt or financing agreement

• Documentation of the vehicle's GVWR (a photo of the door jamb sticker or the manufacturer's spec sheet works)

• Records showing the vehicle was placed in service during the tax year

A mileage tracking app that updates in real time is the most reliable approach. A simple spreadsheet works too, as long as you update it consistently. The key is contemporaneous records: notes made at or near the time of each trip, not reconstructed months later from memory.

Putting It All Together

The Section 179 vehicle deduction list covers a broad range of vehicles, from full-size cargo vans to heavy-duty trucks to large SUVs. However, the rules governing GVWR thresholds, deduction caps, business-use percentages, and recapture risks require careful attention. Buying the right vehicle isn't enough on its own. You also need to:

• Verify the GVWR for the specific trim and model year

• Document your business use throughout the year

• Understand how Section 179 interacts with bonus depreciation before filing
