Bonus depreciation is 100% again, and permanent for qualifying property acquired after 19 January 2025, under the One Big Beautiful Bill Act. The separate section 280F limits on passenger automobiles still apply and are adjusted annually, so a vehicle under the 6,000 lb threshold remains capped regardless of the bonus rate.
For professionals like doctors, lawyers, architects, and consultants, a vehicle is more than transportation—it’s a business tool. Whether it’s traveling to client meetings, court appearances, site visits, or off-site engagements, the IRS allows deductions for business-related vehicle expenses. However, the rules can be nuanced and demand proper recordkeeping.
Understanding IRS guidelines can help you maximize deductions while avoiding costly mistakes.
Who Can Deduct Vehicle Expenses?
To qualify for vehicle deductions, the vehicle must be used for business purposes.
Commuting from home to a regular office is not deductible, but travel to client locations, courts, or off-site meetings typically qualifies.
Professionals Who Typically Qualify:
- Doctors visiting multiple hospitals or clinics
- Lawyers traveling between courthouses and client meetings
- Consultants meeting clients at various sites
- Real estate agents showing multiple properties
Self-employed professionals and business owners (e.g., Schedule C filers or S corps) enjoy the most flexibility in deducting vehicle expenses.
Two Methods for Deducting Vehicle Expenses
The IRS offers two methods for deducting vehicle expenses: the standard mileage rate and the actual expense method.
1. Standard Mileage Rate
The standard mileage rate is the simplest option. For 2026, the IRS standard mileage rate is 72.5 cents per mile for business use. To use this method, you need to track all business miles driven throughout the year using a logbook or mileage-tracking app. This method includes expenses like gas, maintenance, and depreciation within the mileage rate.
2. Actual Expense Method
The actual expense method allows you to deduct the percentage of actual vehicle expenses used for business. These expenses can include:
- Gas and oil
- Maintenance and repairs
- Insurance premiums
- Registration fees
- Depreciation or lease payments
- Car washes and detailing
If you use the vehicle for both personal and business purposes, you can only deduct the portion that applies to business use.
Depreciation and Section 179 Deductions
If your vehicle is used over 50% for business, you may qualify for accelerated depreciation under Section 179.
Heavy SUVs/Trucks (Over 6,000 lbs GVWR):
- May be fully or partially expensed in the first year.
- Popular with high-income professionals who need large vehicles.
Section 179 Limit for 2025:
- Up to $28,900 for qualified vehicles.
- Bonus depreciation may apply to any remaining balance.
Example:
A lawyer purchases a $65,000 SUV (6,500 lbs GVWR) used 100% for business. Eligible for up to $28,900 Section 179 deduction + potential bonus depreciation.
Luxury Vehicle Limits
The IRS imposes limits on depreciation for passenger vehicles considered “luxury vehicles.”
For 2026, the first-year depreciation limit is $20,300 where bonus depreciation applies and $12,300 where it does not with bonus depreciation. SUVs and larger vehicles may qualify for higher limits, but proper classification is essential.
Leased Vehicles
If you lease your vehicle, you can deduct the business-use portion of lease payments.
Other associated expenses like insurance, fuel, and maintenance are also deductible, but you cannot claim depreciation on leased vehicles.
Recordkeeping Requirements
To claim vehicle deductions, you must maintain accurate records of:
- The total and business miles driven annually
- Dates, destinations, and the purpose of each trip
- Receipts for expenses if using the actual expense method
Failure to keep detailed records can result in denied deductions during an audit.
What Travel Is Not Deductible?
- Commuting to a regular office or clinic
- Personal errands or family trips
- Non-business-related vehicle use
Only business-related travel is eligible for deductions, so it’s crucial to distinguish personal from business mileage.
Strategies to Maximize Vehicle Deductions
- Consider purchasing a qualifying SUV or truck for larger Section 179 deductions.
- Use mileage-tracking apps to automate recordkeeping.
- Bundle business errands in a single trip to increase deductible mileage.
- Combine vehicle deductions with other tax-saving strategies like tax preparation services and accountable plans.
Example
If an attorney drives 10,000 business miles in 2026, the standard mileage deduction would be $7,250 (10,000 miles at 72.5 cents). Alternatively, if actual vehicle expenses total $9,000 and 80% of use is for business, the deduction would be $7,200 ($9,000 x 0.8). Comparing both methods annually ensures you choose the highest deduction.
