Yes, an S corporation can claim depreciation on vehicles used for business, subject to the same rules and limitations that apply to other taxpayers. The methods and limitations for depreciating business vehicles are governed by the Internal Revenue Code, Treasury Regulations, and IRS guidance. Below is a comprehensive explanation of the relevant legal details, including the methods allowed, special rules for vehicles, and the process for claiming depreciation.
1. Eligibility to Depreciate Vehicles
An S corporation may depreciate vehicles if:
- The S corporation owns the vehicles (i.e., holds legal title or bears the incidents of ownership such as the obligation to pay for the vehicle, responsibility for maintenance, taxes, and risk of loss).
- The vehicles are used in the corporation’s trade or business or for the production of income.
- The vehicles have a determinable useful life and are expected to last more than one year.
If the S corporation leases vehicles, it generally cannot depreciate the vehicles themselves, but may be able to depreciate capital improvements made to leased vehicles.
2. Depreciation Methods Allowed
A. Modified Accelerated Cost Recovery System (MACRS)
Most business vehicles placed in service after 1986 must be depreciated under MACRS. Under MACRS, vehicles are classified as 5-year property.
i. General Depreciation System (GDS)
- 200% Declining Balance Method (200% DB): This is the default method for 5-year property, including most vehicles. The method allows for accelerated depreciation in the early years, switching to straight line when it yields a greater deduction.
- 150% Declining Balance Method (150% DB): Taxpayers may elect to use this slower method.
- Straight Line Method (SL): Taxpayers may elect to use straight line over the 5-year recovery period.
ii. Alternative Depreciation System (ADS)
- Straight Line Method over 5 years: Required if the vehicle is used 50% or less for qualified business use, or if the vehicle is used predominantly outside the United States, by a tax-exempt entity, or in other special circumstances.
iii. Conventions
- Half-Year Convention: Generally applies, treating all property placed in service during the year as placed in service at the midpoint of the year.
- Mid-Quarter Convention: Applies if more than 40% of the basis of property is placed in service in the last three months of the year.
B. Section 179 Expensing
An S corporation may elect to expense the cost of qualifying vehicles (subject to limits) in the year placed in service under IRC §179. For 2025, the maximum §179 deduction is $2,500,000, reduced dollar-for-dollar by the amount by which the cost of §179 property placed in service exceeds $4,000,000.
- The §179 deduction for SUVs is capped at $31,300 for 2025.
- The vehicle must be used more than 50% for business in the year placed in service.
- The deduction is further limited to the S corporation’s taxable income from the active conduct of a trade or business.
C. Bonus Depreciation (Special Depreciation Allowance)
For 2025, bonus depreciation is generally 40% for property acquired before January 20, 2025, and 100% for property acquired after January 19, 2025, and placed in service in 2025 or later. Bonus depreciation applies after §179 expensing and before regular MACRS depreciation.
- Bonus depreciation is not subject to an annual dollar cap or income limitation.
- The vehicle must be used more than 50% for business.
- For passenger automobiles, the first-year depreciation deduction (including §179 and bonus depreciation) is subject to annual limits (see below).
3. Special Rules and Limitations for Vehicles
A. Passenger Automobile Depreciation Limits
Depreciation deductions (including §179 and bonus depreciation) for passenger automobiles are subject to annual dollar limits under IRC §280F(a). For 2025, the limits for passenger automobiles placed in service in 2025 are:
- 1st year: $20,400 (if bonus depreciation is claimed; $12,400 if not)
- 2nd year: $19,800
- 3rd year: $11,900
- Each succeeding year: $7,160
If the business use is less than 100%, these limits are reduced proportionally.
Definition of Passenger Automobile
A passenger automobile is generally a four-wheeled vehicle manufactured primarily for use on public streets, roads, and highways, and rated at 6,000 pounds gross vehicle weight or less (for trucks and vans, gross vehicle weight).
SUVs and Heavy Vehicles
Certain SUVs and vehicles with a gross vehicle weight rating (GVWR) over 6,000 pounds but not more than 14,000 pounds are not subject to the passenger automobile limits, but are subject to a separate §179 cap ($31,300 for 2025).
B. Listed Property Rules
Vehicles are considered "listed property" under IRC §280F. To claim accelerated depreciation (including §179 and bonus depreciation), the vehicle must be used more than 50% for qualified business use in the year placed in service. If business use drops to 50% or less in a later year, excess depreciation must be recaptured as income, and future depreciation must be computed using the straight line method over the ADS recovery period.
C. Recordkeeping
Adequate records must be maintained to substantiate business use, including mileage logs showing total, business, commuting, and personal miles, as well as the date, destination, and purpose of each trip.
4. Alternative Depreciation Methods
A. Election Out of MACRS
A taxpayer may elect to exclude property from MACRS and use a method not based on a term of years (e.g., unit-of-production or mileage-based method) under IRC §168(f)(1). This is generally rare for vehicles, but the IRS has approved mileage-based depreciation for certain leasing businesses under specific conditions.
5. S Corporation-Specific Considerations
- The §179 deduction is limited at both the S corporation and shareholder level. The S corporation allocates the deduction to shareholders, who must apply their own limitations.
- Depreciation deductions flow through to shareholders on Schedule K-1 and are subject to basis and at-risk limitations at the shareholder level.
6. Summary of Steps for S Corporations
- Determine vehicle eligibility (ownership, business use, useful life).
- Select depreciation method (default is MACRS 200% DB; may elect 150% DB or SL; must use SL/ADS if required).
- Apply §179 expensing (if desired and eligible, up to annual and vehicle-specific limits).
- Apply bonus depreciation (if eligible and not opted out, subject to annual limits for passenger autos).
- Apply MACRS depreciation to remaining basis.
- Apply annual depreciation caps for passenger automobiles.
- Maintain adequate records to substantiate business use and compliance with listed property rules.
- Report depreciation on Form 4562 and allocate to shareholders via Schedule K-1.
In summary: An S corporation can claim depreciation on vehicles used for business, using MACRS (default 200% declining balance over 5 years), with the option to elect §179 expensing and bonus depreciation, subject to annual and vehicle-specific limits. Passenger automobiles are subject to annual depreciation caps. Vehicles must be used more than 50% for business to qualify for accelerated methods, and detailed records must be kept. Alternative methods (such as mileage-based) are available only by election and in limited circumstances.
