Vehicle Deductions for Business Owners: Mileage vs. Actual Expenses
If you use your vehicle for business, you can deduct those costs — but you need to choose the right method and keep the right records. Here's how to maximize your vehicle deduction.
Using your personal vehicle for business is one of the most common — and most underutilized — tax deductions for small business owners. Here's how to claim it correctly and maximize your deduction.
Two Methods to Choose From
Standard Mileage Rate
Deduct a flat rate per business mile driven. For 2026, the IRS standard mileage rate is 70 cents per mile.
Example: 10,000 business miles × $0.70 = $7,000 deduction.
Pros: Simple, no need to track actual expenses. Cons: May be lower than actual expenses for newer or more expensive vehicles.
Actual Expense Method
Track all vehicle expenses and deduct the business-use percentage:
- Gas
- Insurance
- Registration and license fees
- Repairs and maintenance
- Depreciation (or lease payments)
- Car washes
Example: $12,000 in total vehicle expenses, 60% business use = $7,200 deduction.
Pros: Often higher deduction for expensive vehicles or high fuel costs. Cons: Requires detailed record-keeping.
Which Method Should You Choose?
Calculate both and pick the higher one — but with a catch: if you use the actual expense method in the first year you place a vehicle in service, you must continue using it for that vehicle. The standard mileage rate offers more flexibility.
What Records Do You Need?
Regardless of method, you must keep a mileage log that records:
- Date of each trip
- Business purpose
- Starting and ending odometer readings (or total miles)
- Destination
Apps like MileIQ or QuickBooks Online's mileage tracking make this easy.
What Doesn't Count as Business Mileage
- Commuting from home to your regular office
- Personal errands
- Trips that are primarily personal with a minor business purpose
