Which Ram Trucks Qualify for the Section 179 Tax Deduction by GVWR?

Ram commercial vehicles with a Gross Vehicle Weight Rating (GVWR) above 6,000 pounds can qualify for the Section 179 deduction. The vehicle must be used more than 50% for business. Qualifying models on our lot include the 2026 Ram 1500 Tradesman®, the heavy-duty 2026 Ram 2500 Tradesman, and the cargo-focused 2026 Ram ProMaster® Tradesman. Vehicles rated above 6,000 pounds fall outside the passenger-automobile depreciation caps in Internal Revenue Code Section 280F. That exclusion is what opens the door to first-year expensing.

How GVWR Determines Section 179 Treatment

The 6,000-Pound Threshold

GVWR decides how a work vehicle is treated for tax expensing. Curb weight does not. Vehicles rated from 6,001 to 14,000 pounds sit outside the Section 280F passenger-car depreciation limits. The IRS explains those limits in Publication 946, How To Depreciate Property.

The Heavy-SUV Cap and Its Three Exceptions

For tax year 2026, sport utility vehicles in that weight band face a Section 179 cap of $32,000 per vehicle. Three configurations escape the cap entirely.

The first is a full-size pickup with a cargo bed of at least six feet of interior length that is not readily accessible from the passenger compartment. The second is a cargo van with a fully enclosed cargo area and no seating behind the driver. The third is a vehicle designed to seat more than nine passengers behind the driver’s seat, which covers shuttle and passenger-van builds. All three qualify for the full Section 179 limit. Bed length is the detail most buyers miss. Our guide to Ram truck bed configurations covers which box lengths are offered on each model.

Where to Find Your GVWR

The GVWR appears on the certification label inside the driver’s-side door jamb. Check it on the specific unit you are buying. Cab, bed, and drivetrain choices all move the number.

2026 Section 179 Limits at a Glance

The figures below come from IRS Revenue Procedure 2025-32, which sets the inflation-adjusted amounts for tax years beginning in 2026.

Ram Commercial Models and Their Section 179 Position

2026 Ram 1500 Tradesman

The Tradesman comes in Quad Cab and Crew Cab configurations. Two bed lengths are offered across three cab and bed combinations. Four engines are available across the 2026 Ram 1500 lineup: the 3.6L Pentastar® V6 with eTorque at 305 horsepower, the 3.0L Hurricane® twin-turbo I6 at 420 horsepower, a high-output Hurricane at 540 horsepower, and the returning 5.7L HEMI® V8 with eTorque at 395 horsepower. The Pentastar V6, standard-output Hurricane I6, and 5.7L HEMI V8 are all available on the Tradesman. Every engine pairs with an eight-speed automatic transmission.

Tradesman gross vehicle weight ratings run from 6,800 to 7,200 pounds, according to the 2026 Ram 1500 Payload & Towing Guide. Every configuration clears the 6,000-pound threshold. Full trim and powertrain detail is in our 2026 Ram 1500 overview.

2026 Ram 2500 Tradesman

The Ram 2500 carries a standard 6.4L HEMI V8 producing 405 horsepower and 429 pound-feet of torque. The 6.7L Cummins® High-Output Turbo Diesel is available, rated at 430 horsepower and 1,075 pound-feet. Gross vehicle weight ratings across the 2026 Ram 2500 lineup run from 8,565 to 11,440 pounds, per the 2026 Ram Heavy Duty Payload & Towing Guide. That places the truck well into heavy-duty territory, where full Section 179 expensing applies up to the annual limits.

2026 Ram ProMaster Tradesman

For delivery fleets, tradespeople, and mobile service providers working the industrial corridors along Sierra Avenue in Fontana, the ProMaster Tradesman is a purpose-built cargo platform. It is powered by a 3.6L Pentastar V6 in a front-wheel-drive layout.

One qualification note matters here. The cargo-van exception requires no seating behind the driver. It applies to cargo configurations only. Window van and crew van builds with rear seating do not qualify under that exception. A window van configured to seat more than nine passengers behind the driver may instead qualify under the seating-capacity exception. Our 2026 Ram ProMaster fleet guide covers the roof heights, wheelbases, and body styles available.

Bed Length and the Six-Foot Rule

Because the six-foot bed rule decides whether a pickup escapes the heavy-SUV cap, the configuration you choose changes the tax outcome. Bed dimensions below come from the OEM payload and towing guides linked above.

Maximum towing and payload capacity figures are based on properly equipped vehicles and vary by configuration. Do not exceed any weight rating. See your owner’s manual and the vehicle’s door-jamb label for specific capacities.

This information is provided for general educational purposes only and does not constitute tax, legal, or accounting advice. Eligibility for the Section 179 deduction, bonus depreciation, and any related federal or state tax treatment depends on your individual circumstances, your business’s tax position, and current law, which is subject to change. Vehicle weight ratings vary by configuration — always confirm the Gross Vehicle Weight Rating on the vehicle’s door-jamb certification label. Consult a qualified tax professional regarding your specific situation before making a purchase decision.

What Business-Use Percentage Is Required for Section 179?

How the Percentage Is Calculated

Claiming Section 179 on a vehicle requires more than 50% use in active business operations during the tax year. The percentage is business miles divided by total annual miles. Total miles include business, personal, and commuting trips.

If business use is 50% or below, the vehicle fails the predominant-use test. Section 179 cannot be elected. Bonus depreciation is unavailable. The vehicle must instead be depreciated using the straight-line method under the Alternative Depreciation System over a five-year recovery period. Publication 946 covers the listed-property rules in detail.

What Counts as Business Mileage

Substantiating the percentage requires a contemporaneous mileage log. Each entry should record the date, starting point, destination, miles driven, and business purpose of the trip.

The IRS treats driving from a personal residence to a primary place of business as personal commuting mileage. Travel between job sites counts as business mileage. So do trips to client meetings, vendor visits, and equipment pickups. Publication 463, Travel, Gift, and Car Expenses sets out the recordkeeping standards.

New and Used Vehicles

Section 179 applies to both new and used vehicles. The truck must be new to your business entity. It must also be acquired in an arm’s-length transaction from an unrelated party. A vehicle bought from a related business or a family member does not qualify.

Documentation and Filing

Retain mileage records, purchase invoices, and registration documents in your business tax files. The Section 179 election is made on IRS Form 4562. If a truck runs 80% business use, 80% of its cost is the portion eligible for expensing, subject to the statutory limits.

How Bonus Depreciation Combines With Section 179

Section 179 and bonus depreciation work in sequence. Section 179 is elected first, up to the statutory limits. Then 100% bonus depreciation can be applied to any remaining first-year basis.

For tax years beginning in 2026, the maximum Section 179 deduction is $2,560,000. It phases out dollar for dollar once qualifying property placed in service exceeds $4,090,000. It disappears entirely at $6,650,000. These figures reflect the permanent increases made by the One Big Beautiful Bill Act (Public Law 119-21), as adjusted for inflation. One hundred percent bonus depreciation has been restored. It carries no aggregate spending cap and no business-income restriction.

The distinction between the two matters most when income is tight. Section 179 cannot create or increase a net operating loss, and it is limited to net business income. Bonus depreciation can generate a loss that carries forward against future taxable earnings. For fleet operators structuring year-end capital expenditures, that difference often decides which tool does the heavy lifting.

What Happens If Business Use Drops Below 50% Later?

If business use of a Section 179 vehicle falls to 50% or below during the recovery period, recapture rules apply under Internal Revenue Code Section 280F(b)(2). The excess deduction previously claimed is reported as ordinary income in Part IV of IRS Form 4797. It is not reported on Form 4562, which is the election form.

The recapture amount is the difference between two figures. The first is the accelerated deduction actually claimed. The second is the straight-line depreciation that would have been allowed under the Alternative Depreciation System over the same period. From that year forward, the vehicle loses eligibility for accelerated expensing, and the remaining basis is depreciated straight-line.

Reviewing vehicle usage quarterly is the practical defense. If business mileage starts slipping relative to personal miles, shifting personal driving to another vehicle keeps the work truck above the threshold.

Eligibility for the Section 179 deduction, bonus depreciation, and any related federal or state tax treatment depends on your individual circumstances, your business’s tax position, and current law, which is subject to change.

Consult a qualified tax professional regarding your specific situation before making a purchase decision.

Commercial Financing and Leasing for Qualifying Ram Trucks

Once you have identified a configuration that qualifies, the next step is structuring the acquisition. Fontana Chrysler Dodge Jeep Ram offers commercial financing and leasing structures. These include TRAC leases, commercial lines of credit, and installment purchase agreements. They are provided on approved credit through Stellantis Financial Services, the Ram brand’s commercial lending partner, and are available to business entities across San Bernardino County.

A Terminal Rental Adjustment Clause lease can help preserve working capital. Under a TRAC lease, the business agrees to a predetermined residual value at the end of the term. If the vehicle sells for more than that residual, the business receives the surplus. If it sells for less, the business covers the difference. The structure keeps monthly payments manageable. It also leaves fleet maintenance and mileage decisions with the operator.

You can review the full Ram commercial lineup, including the models covered here, on our Ram commercial vehicle page.

Subject to credit approval by Stellantis Financial Services, Inc. Not all buyers will qualify. Higher financing or lease rates apply for buyers with lower credit ratings. Length of contract term may be limited.

Commercial financing and lease terms are subject to credit approval and program availability. Rates, residual values, and terms are set by the lender and the dealer and are subject to change at any time. Not all applicants will qualify. See Fontana Chrysler Dodge Jeep Ram for current program details.

Common Questions About Section 179 for Ram Commercial Trucks

Does truck bed length affect Section 179 deduction caps on a Ram 1500?

Bed length does not change weight eligibility if the vehicle clears the 6,000-pound GVWR threshold. It changes which cap applies. A full-size pickup with a cargo bed of at least six feet of interior length falls outside the heavy-SUV rule and qualifies for the full Section 179 limit. Pickups with shorter beds may fall under the heavy-SUV cap depending on body configuration, limiting the Section 179 portion to $32,000 for 2026.

Can a business claim Section 179 on a pre-owned Ram truck?

Yes. Section 179 applies to both new and qualifying used vehicles. The requirement is that the truck be new to your business entity and purchased in an arm’s-length transaction. A pre-owned 2026 Ram 2500 Tradesman can provide first-year write-offs, provided it was not acquired from a related business entity or family member.

What is the maximum Section 179 deduction limit for 2026?

For tax years beginning in 2026, the maximum Section 179 deduction is $2,560,000. The phase-out begins at $4,090,000 in total qualifying purchases and reduces the deduction dollar for dollar above that level. At $6,650,000 in qualifying purchases placed in service, the deduction is eliminated for that year.

Is the Section 179 deduction limited by business taxable income?

Yes. The deduction cannot exceed net taxable income from the active conduct of your business. If an entity earns $50,000 in net business income and buys a $70,000 work truck, the Section 179 write-off is capped at $50,000. The remaining $20,000 carries forward to future years, or can be claimed in year one through 100% bonus depreciation.

What documentation supports a Section 179 claim in an audit?

Detailed mileage logs showing business purpose, purchase receipts, proof of registration, and Form 4562 filed with the return. Mileage records must separate business travel from personal trips and commuting miles, beginning from the date the vehicle was placed in service.

This information is provided for general educational purposes only and does not constitute tax, legal, or accounting advice. Eligibility for the Section 179 deduction, bonus depreciation, and any related federal or state tax treatment depends on your individual circumstances, your business’s tax position, and current law, which is subject to change. Vehicle weight ratings vary by configuration — always confirm the Gross Vehicle Weight Rating on the vehicle’s door-jamb certification label. Consult a qualified tax professional regarding your specific situation before making a purchase decision.
