Self-employed drivers have two options for deducting vehicle costs: the standard mileage rate (multiply business miles by the IRS rate per mile) or the actual expense method (deduct real costs multiplied by the business-use percentage). Choosing the wrong method can cost hundreds or thousands of dollars in missed deductions each year. This guide compares both methods with real numbers and tells you which one to use for your situation.
Expert Note
The 2026 IRS standard mileage rate has not been officially announced as of publication. The 2025 rate was 67 cents per mile. The IRS typically announces the new rate in December for the following year. Check irs.gov for the current 2026 rate before filing. All examples below use 67 cents as a planning baseline.
Method 1: Standard Mileage Rate
The standard mileage rate is the simplest method. Multiply your total business miles driven during the year by the IRS rate. The result is your vehicle deduction. For 2025 (67 cents): 10,000 business miles x $0.67 = $6,700 deduction.
Record-keeping requirement: you need only a mileage log showing date, destination, business purpose, and miles for each business trip. You do not need to track individual fuel receipts, maintenance costs, or insurance premiums.
When Standard Mileage Wins
- Fuel-efficient vehicles (30+ MPG) with lower actual fuel costs per mile
- Lower-cost vehicles with minimal depreciation
- High business-use percentage (80%+ business use)
- Recent vehicle purchase where you want to preserve depreciation options
Method 2: Actual Expense Method
The actual expense method deducts real vehicle costs multiplied by the percentage of total driving that was for business. Qualifying expenses include: gas and oil, tires, repairs and maintenance, insurance, registration fees, and depreciation.
Record-keeping requirement: all receipts for every qualifying expense, plus a mileage log to calculate the business-use percentage. The Gas Budget Worksheet captures fuel data in a format suitable for actual expense documentation.
When Actual Expense Wins
- Fuel-inefficient vehicles (pickup trucks, large SUVs) with high actual fuel costs
- Expensive vehicles with significant annual depreciation
- Vehicles requiring frequent repairs or specialized maintenance
- Lower business-use percentages where the per-mile rate underestimates actual costs
Side-by-Side Example
Consider a self-employed contractor driving a full-size pickup truck 20,000 miles for business out of 33,333 total miles (60% business use) in a year.
| Cost Category | Annual Total | Business % (60%) | Deductible |
|---|---|---|---|
| Fuel (18 MPG, $3.50/gal) | $6,481 | 60% | $3,889 |
| Insurance | $2,400 | 60% | $1,440 |
| Maintenance and repairs | $800 | 60% | $480 |
| Depreciation | $6,000 | 60% | $3,600 |
| Total Actual Expense | $15,681 | 60% | $9,409 |
| Standard Mileage (67¢ x 20,000) | $13,400 | N/A | $13,400 |
In this example, the standard mileage rate produces a $13,400 deduction versus $9,409 for actual expenses. The standard rate wins by $3,991 despite the truck's high actual costs, because the 67-cent rate is set to approximate average vehicle costs including efficient vehicles, and the truck's efficiency disadvantage is more than compensated by the high mileage count.
Eligibility Rules
- You must choose the standard mileage rate in the first year the vehicle is placed in service for business
- You cannot switch to standard mileage after using accelerated depreciation (MACRS or Section 179) on the vehicle
- You cannot use the standard mileage rate if you operate five or more vehicles simultaneously (fleet)
- Leased vehicles can use standard mileage but must use it for the entire lease period once chosen
Record-Keeping Requirements
Mileage Log Requirements
Every business trip must be documented with: date of the trip, starting and ending destination or description of route, business purpose of the trip, and odometer reading or total miles for the trip. The IRS requires contemporaneous records, meaning logs created at the time of the trip, not reconstructed at year end.
Recommended Tracking Apps
MileIQ and Everlance are the most widely used mileage tracking apps for self-employed individuals. Both use GPS to automatically log trips and allow one-swipe classification as business or personal. TripLog offers more detailed reporting suitable for tax preparation. All three generate IRS-compliant mileage reports exportable for tax filing.
Special Situations
Rideshare Drivers
Uber and Lyft drivers typically benefit most from the standard mileage rate because their vehicles often have a high business-use percentage (all driving while the app is on counts as business mileage). The standard rate already includes depreciation, which simplifies the calculation for high-mileage rideshare vehicles that depreciate quickly.
Delivery Drivers
DoorDash, Instacart, and Amazon Flex drivers are treated as independent contractors. Vehicle expenses are deductible on Schedule C. Standard mileage rate typically produces higher deductions for delivery drivers due to high mileage combined with often-modest vehicles where actual expense depreciation is lower.
Pro Tip
In your first year with a new business vehicle, calculate both methods before filing. Most tax software and some mileage apps will run the comparison for you. The method you choose in year one for a vehicle determines which method you can use in future years, so the first-year choice has long-term consequences.
