The Basics

What Is the Section 179 Deduction for Vehicles?

Section 179 of the IRS tax code allows businesses to deduct the full purchase price of qualifying equipment and vehicles in the year of purchase, rather than depreciating the cost over several years. For vehicles, the key threshold is a Gross Vehicle Weight Rating (GVWR) of over 6,000 pounds.

Vehicles that cross this threshold — including many popular SUVs, trucks, and vans — can qualify for an immediate, first-year write-off that dramatically reduces your taxable income. The vehicle must be used for business purposes, and the deduction is limited to your business's taxable income for the year.

🏋️

Over 6,000 lbs GVWR

Vehicles with a Gross Vehicle Weight Rating above 6,000 lbs qualify for the full Section 179 deduction — up to the annual limit.

SUVs Pickup trucks Cargo vans Box trucks
🚗

Under 6,000 lbs GVWR

Passenger vehicles below the threshold are subject to strict luxury auto limits — far lower than the full Section 179 amount.

Sedans Compact SUVs Most coupes
📋

Business Use Requirement

The vehicle must be used more than 50% for business. Your deduction is prorated based on the actual business-use percentage.

Mileage logs Business trips Delivery routes

Important: Section 179 applies to the tax year the vehicle is placed in service — not necessarily when it's ordered or paid for. The vehicle must be operational and used for business before December 31st of the tax year you're claiming.

2025 Limits

Section 179 Vehicle Deduction Limits

Not all qualifying vehicles share the same deduction limit. The IRS distinguishes between heavy SUVs (which have a separate cap) and other qualifying vehicles like trucks and vans.

Vehicle Type
2025 Max Deduction
Notes
Non-SUV Trucks, Vans & Other Vehicles over 6,000 lbs
Up to $1,220,000
Full Section 179 limit applies. Includes pickup trucks with a cargo bed ≥ 6 ft.
Heavy SUVs (6,001–14,000 lbs GVWR)
$30,500
Subject to a separate SUV cap. Bonus depreciation may apply to the remainder.
Passenger Vehicles Under 6,000 lbs
~$12,400
Subject to luxury auto limits. Much lower cap regardless of vehicle cost.
Section 179 Phase-Out Threshold
$3,050,000

Heavy SUV cap: Vehicles classified as SUVs with a GVWR between 6,001 and 14,000 lbs are subject to a $30,500 annual Section 179 cap (2025). However, you may be able to claim bonus depreciation on the remaining cost. Consult your tax advisor for the optimal strategy.

Which Vehicles Qualify

Popular Vehicles Over 6,000 lbs That May Qualify

The GVWR is listed on the door jamb sticker or the manufacturer's specifications — not the vehicle's curb weight. Many popular business vehicles exceed the threshold. Here are common examples:

Vehicle Approx. GVWR Section 179 Treatment Qualifies?
Ford F-150 / F-250 / F-350 7,000–14,000 lbs Full 179 (pickup with 6-ft bed) or SUV cap Yes
Chevy Silverado / GMC Sierra 7,000–10,000 lbs Full 179 (pickup) or SUV cap Yes
Ram 1500 / 2500 / 3500 6,900–14,000 lbs Full 179 deduction Yes
Cadillac Escalade ~7,100 lbs Heavy SUV cap ($30,500) Capped
Chevrolet Suburban / Tahoe ~7,500 lbs Heavy SUV cap ($30,500) Capped
Ford Expedition ~7,300 lbs Heavy SUV cap ($30,500) Capped
Mercedes GLS / BMW X7 ~6,900–7,000 lbs Heavy SUV cap ($30,500) Capped
Tesla Model 3 / Model S ~4,800–5,600 lbs Luxury auto limits apply Under Limit
Ford Transit / Ram ProMaster Van 8,550–11,030 lbs Full 179 deduction (non-SUV) Yes
Box Trucks / Sprinter Vans 8,500–11,000 lbs Full 179 deduction Yes

Always verify GVWR: Check the door jamb sticker on the actual vehicle — not just the model name. GVWR can vary by trim level, drivetrain, and towing package. A vehicle that looks similar to a qualifying model may fall below the 6,000-lb threshold.

How to Claim It

How to Claim the Section 179 Vehicle Deduction

Claiming Section 179 for a vehicle involves a few key steps on your business tax return. Here's what the process looks like:

1

Verify the Vehicle Qualifies

Confirm the GVWR exceeds 6,000 lbs (check the door jamb), the vehicle is owned (not leased) by your business, and it was placed in service during the tax year.

2

Document Business Use

Maintain a mileage log or other records showing business vs. personal use. The deduction is prorated to your business-use percentage, and you must use the vehicle more than 50% for business.

3

Complete IRS Form 4562

Section 179 elections are made on Form 4562 (Depreciation and Amortization). Part I covers the Section 179 deduction. Your tax software or CPA will populate this from your vehicle purchase information.

4

Consider Bonus Depreciation for the Remainder

If your vehicle cost exceeds the Section 179 limit (or if you hit the SUV cap), you may be able to take bonus depreciation on the remaining balance. Bonus depreciation rates vary by year — consult your tax advisor.

5

File Before the Deadline

The election must be made on a timely filed return (including extensions). You cannot go back and claim Section 179 after the fact on an amended return in most cases.

Your Effective Deduction
Section 179 Deduction = Vehicle Cost × Business-Use %

If you purchase a $90,000 qualifying pickup truck and use it 80% for business, your Section 179 deduction is $72,000 — reducing your taxable income by that amount in year one.

Finance + Deduct

You Can Finance a Vehicle and Still Claim Section 179

One of the most powerful aspects of Section 179 is that you can take the full deduction even if you financed the vehicle. You don't have to pay cash to write it off — a business auto loan or equipment loan qualifies.

💳

Business Auto Loan

Finance your qualifying vehicle through a lender. Take the full Section 179 deduction in year one — even though you're making monthly payments.

Low down payment Full deduction Preserve cash
📝

Equipment Financing

Many heavy work vehicles qualify as equipment. Equipment loans often have faster approval and more flexible terms than traditional auto loans.

Fast funding Flexible terms Up to 100% financing
⚖️

Lease vs. Buy

If you lease a vehicle, Section 179 does not apply. Instead, you deduct the business-use portion of lease payments. Buying generally produces a larger first-year deduction.

Buy = 179 eligible Lease = payment deduction

The tax-leverage strategy: Financing a qualifying vehicle can create a scenario where your Section 179 tax savings in year one exceed your out-of-pocket down payment — effectively letting the IRS help fund your vehicle purchase.

FAQ

Frequently Asked Questions

What vehicles qualify for the Section 179 deduction?
Any business vehicle with a Gross Vehicle Weight Rating (GVWR) over 6,000 lbs that is purchased (not leased) and used more than 50% for business qualifies for Section 179. This includes pickup trucks, cargo vans, box trucks, and many large SUVs. Lighter passenger vehicles are subject to the much lower "luxury auto" limits instead.
How do I find a vehicle's GVWR?
The GVWR is printed on the door jamb sticker (inside the driver's door frame) of every vehicle. You can also find it in the owner's manual or on the manufacturer's website by searching the specific year, make, model, and trim. Note that GVWR is different from curb weight — it represents the maximum loaded weight the vehicle is rated to handle.
What is the Section 179 deduction limit for SUVs?
For tax year 2025, heavy SUVs (GVWR between 6,001 and 14,000 lbs) are subject to a $30,500 Section 179 cap. This is separate from the general $1,220,000 Section 179 limit. You may be able to claim bonus depreciation on the cost exceeding this cap — consult a tax professional to optimize your strategy.
Can I deduct a vehicle over 6,000 lbs if I financed it?
Yes. Section 179 does not require you to pay cash for the vehicle. If you finance a qualifying vehicle with a business auto loan or equipment loan, you can still claim the full deduction (subject to limits) in the year the vehicle is placed in service — even though you're still making loan payments.
What is the difference between Section 179 and bonus depreciation?
Both allow accelerated first-year deductions, but they work differently. Section 179 is elected on a per-asset basis and is limited to your business's taxable income for the year. Bonus depreciation is automatic (unless you opt out), can create a net operating loss, and applies to new and used property. Many businesses use both in combination to maximize first-year deductions.
What if I use my vehicle for both business and personal purposes?
Your Section 179 deduction is reduced to reflect the business-use percentage. For example, if you use a qualifying vehicle 70% for business, your deduction is limited to 70% of the vehicle's cost (up to the annual cap). You must also use the vehicle more than 50% for business to qualify at all — if business use drops below 50% in a later year, you may need to recapture some of the deduction.
