Yes, businesses can accelerate depreciation for trucks by leveraging weight-based tax provisions, specifically under the rules for bonus depreciation (special depreciation allowance) and Section 179 expensing, as well as by avoiding the “luxury auto” depreciation limits that apply to lighter vehicles. The ability to do so depends on the truck’s gross vehicle weight rating (GVWR) and how it is used in the business.
1. Bonus Depreciation (Special Depreciation Allowance) – Section 168(k)
Eligibility and Acceleration:- Under IRC §168(k), businesses can claim bonus depreciation (special depreciation allowance) for qualified property, which includes most new and used trucks, provided they are acquired and placed in service during the applicable tax year and used more than 50% for business.- For 2025 and later, the bonus depreciation rate is 100% for property acquired and placed in service after January 19, 2025, due to recent legislative changes. For property acquired before that date, the rate is 40% in 2025, 20% in 2026, and 0% in 2027 and after, unless the property qualifies under the new law for 100% expensing.
Weight-Based Advantage:- Trucks with a GVWR over 6,000 pounds are not subject to the “luxury auto” depreciation limits of IRC §280F. This means the full cost of the truck can be deducted as bonus depreciation in the first year, subject to business use and other requirements.- Lighter trucks (GVWR 6,000 pounds or less) are subject to annual depreciation caps, which can significantly limit the first-year deduction, even if bonus depreciation is available.
Example:- A business purchases a new pickup truck with a GVWR of 7,000 pounds for $60,000 and uses it 100% for business. The business can claim 100% bonus depreciation and deduct the full $60,000 in the year the truck is placed in service, provided all other requirements are met.
2. Section 179 Expensing – IRC §179
Eligibility and Acceleration:- Section 179 allows businesses to expense the cost of qualifying property, including trucks, up to an annual limit ($2,500,000 for 2025, with a phase-out beginning at $4,000,000).- The deduction is limited to the business’s taxable income, with any excess carried forward.
Weight-Based Advantage:- For trucks and vans with a GVWR over 6,000 pounds but not more than 14,000 pounds, the Section 179 deduction is generally capped at $25,000 per vehicle, unless the truck meets certain exceptions (e.g., cargo area at least 6 feet in length, seating for more than nine behind the driver, or no seating behind the driver and no body section protruding more than 30 inches ahead of the windshield).- If the truck meets one of these exceptions, the full Section 179 limit may apply, allowing the business to expense the entire cost (up to the annual limit) in the first year.
3. Luxury Auto Depreciation Limits – IRC §280F
- Trucks and vans with a GVWR of 6,000 pounds or less are subject to annual depreciation caps (the “luxury auto” limits), which restrict the amount that can be deducted each year, even if bonus depreciation or Section 179 is available.
- Trucks and vans over 6,000 pounds GVWR are not subject to these limits, allowing for full expensing under bonus depreciation or Section 179 (subject to the $25,000 cap and exceptions for Section 179).
4. Depreciation Methods and Conventions
- For trucks not subject to the luxury auto limits, businesses can use the Modified Accelerated Cost Recovery System (MACRS) with the 200% declining balance method, switching to straight line when advantageous, and apply the half-year or mid-quarter convention as appropriate.
5. Summary of Weight-Based Provisions
- Trucks and vans over 6,000 pounds GVWR: Not subject to luxury auto limits; eligible for 100% bonus depreciation and/or full Section 179 expensing (subject to the $25,000 cap unless an exception applies).
- Trucks and vans 6,000 pounds GVWR or less: Subject to annual depreciation caps; bonus depreciation and Section 179 deductions are limited by these caps.
6. Caveats and Considerations
- The vehicle must be used more than 50% for business to qualify for bonus depreciation and Section 179.
- If business use drops to 50% or less, recapture of excess depreciation may be required.
- Proper documentation of business use and vehicle classification is essential.
- State tax treatment may differ from federal rules.
7. Conclusion
Businesses can accelerate depreciation for trucks by leveraging weight-based tax provisions. Trucks and vans with a GVWR over 6,000 pounds are not subject to the luxury auto depreciation limits, allowing for full expensing under bonus depreciation and, in many cases, Section 179. This provides a significant tax benefit by enabling businesses to deduct the full cost of qualifying vehicles in the year they are placed in service, provided all other requirements are met.
