Business Mileage Deduction Overview
If you use your personal vehicle for business purposes, you can deduct either:
- Standard mileage rate: A set amount per mile driven
- Actual expenses: The actual costs of operating your vehicle
The choice can save—or cost—you thousands, so it’s important to understand both methods.

Which Method Should You Choose?
Comparison Calculator
| Factor | Standard Mileage | Actual Expenses |
|---|---|---|
| Business miles | ___ miles | ___ miles |
| Rate/Cost | × $0.67 | × ___% of total costs |
| Deduction | $_____ | $_____ |
When to Choose Standard Mileage:
- You drive an average or inexpensive vehicle
- You want simplicity
- Your business use percentage is moderate (50-75%)
- You don’t want to track expenses
When to Choose Actual Expenses:
- You have an expensive or luxury vehicle
- Your operating costs are high
- Your business use percentage is very high (90%+)
- You lease your vehicle
Example Comparison
Scenario:
- 10,000 business miles
- Total vehicle expenses: $8,000
- Business use: 80%
| Method | Calculation | Deduction |
|---|---|---|
| Standard | 10,000 × $0.67 | $6,700 |
| Actual | $8,000 × 80% | $6,400 |
Result: Standard mileage is $300 better
Mileage Tracking Requirements
What to Record for Each Trip
- Date: When the trip occurred
- Destination: Where you went
- Purpose: Business reason for the trip
- Starting odometer: Beginning reading
- Ending odometer: Final reading
- Total miles: Distance driven
Sample Mileage Log Entry
| Date | Destination | Purpose | Start Odo | End Odo | Miles |
|---|---|---|---|---|---|
| 1/15/24 | Client ABC, 123 Main St | Project meeting | 45,230 | 45,268 | 38 |
| 1/18/24 | Office Depot | Buy supplies | 45,420 | 45,432 | 12 |
What Counts as Business Mileage?

| Temporary job sites | ✅ Yes | If not regular location |
| Regular commute | ❌ No | To/from tax home |

Mileage Tracking Apps and Methods
Recommended Tracking Methods
| Method | Pros | Cons |
|---|---|---|
| Apps (MileIQ, Everlance) | Automatic GPS tracking | Monthly cost ($5-15/mo) |
| Spreadsheet | Free, customizable | Manual entry |
| Paper logbook | Simple, no tech | Easy to lose/falsify |
| Calendar + Map | Integrates with schedule | Requires calculation |
Best Practices
- Track contemporaneously: Record at time of trip, not from memory
- Be specific: “Client meeting” not just “business”
- Include addresses: Helps verify distances
- Note deviations: If you added personal stops
- Save supporting docs: Meeting invites, receipts
- Photograph odometer: At start/end of year
Depreciation (Actual Expenses Method)
Vehicle Depreciation Limits
| Year Placed in Service | 1st Year | 2nd Year | 3rd Year | 4th+ Years |
|---|---|---|---|---|
| Standard vehicle | $12,200 | $19,500 | $11,700 | $6,960 |
| Bonus depreciation* | +$8,000 | - | - | - |
*Bonus depreciation for 2024 is 60% (declining from 100% in 2022)
Luxury Auto Limits
If your vehicle cost exceeds certain thresholds, depreciation is limited:
| Vehicle Cost | Depreciation Limit |
|---|---|
| Under $60,000 | Normal depreciation |
| $60,000 - $80,000 | Limited annual amounts |
| Over $80,000 | Subject to “luxury auto” caps |
Section 179 for Vehicles
For heavy vehicles (GVWR over 6,000 lbs):
- Can deduct up to $30,500 in first year
- Common for SUVs, trucks, vans
Special Situations
Leased Vehicles
| Method | How It Works |
|---|---|
| Standard mileage | Same as owned - 67¢/mile |
| Actual expenses | Deduct business % of lease payments |
Note: If you use actual expenses for a leased vehicle, you may need to include an “inclusion amount” in income (reduces deduction slightly).
Multiple Vehicles
- Track mileage separately for each vehicle
- Can use different methods for different vehicles
- Allocate expenses to each vehicle separately
Mixed-Use Vehicles
Calculate business use percentage:
Business Miles ÷ Total Miles = Business Use %Example:
- Business miles: 8,000
- Personal miles: 4,000
- Total miles: 12,000
- Business use: 66.7%
Apply this percentage to actual expenses.
Common Mistakes to Avoid
- Estimating mileage: IRS requires actual records
- Including commute: Regular commute is never deductible
- Double-dipping: Can’t deduct same expense twice
- No contemporaneous log: Recreating at tax time is not compliant
- Switching methods: Once you choose actual expenses, you can’t switch back
- Forgetting parking/tolls: These are separate from mileage
- Not tracking personal miles: Need total to calculate percentage
Record Keeping Timeline
What to Keep and for How Long
| Document | Keep For |
|---|---|
| Mileage log | 3-7 years |
| Gas receipts | 3-7 years |
| Repair invoices | 3-7 years |
| Insurance statements | 3-7 years |
| Registration | 3-7 years |
| Vehicle purchase/sale docs | 7 years after disposal |

<FAQ questions={[ { question: “Can I deduct mileage if I don’t own the car?”, answer: “Yes, if you’re using a car for business purposes, you can deduct mileage whether you own it, lease it, or even borrow it. The deduction is based on business use, not ownership. However, if someone else (like an employer) reimburses you for mileage, you cannot also deduct it.” }, { question: “What if I forget to track some business miles?”, answer: “The IRS requires contemporaneous records. If you miss some trips, don’t estimate them. Only claim miles you can substantiate with records. Going forward, use a tracking app to capture all trips automatically.” }, { question: “Can I switch from actual expenses to standard mileage?”, answer: “Generally, no. If you use actual expenses in the first year you place a vehicle in service for business, you cannot switch to the standard mileage rate for that vehicle in later years. However, you can use standard mileage in the first year and switch to actual expenses later.” }, { question: “Is mileage to a second job deductible?”, answer: “If you have two jobs, the mileage between them is deductible. However, mileage from home to your first job and from your second job back home are considered commuting and are not deductible.” }, { question: “What about mileage for volunteer work?”, answer: “Mileage for charitable volunteer work is deductible at 14 cents per mile (2024 rate). This is claimed as a charitable contribution on Schedule A, not as a business expense on Schedule C.” }, { question: “Can I deduct parking and tolls with the standard mileage method?”, answer: “Yes! Parking fees and tolls are separate from the standard mileage rate and can be deducted in addition to the per-mile rate. This applies to both the standard mileage and actual expenses methods.” }, { question: “How does the IRS verify mileage claims?”, answer: “The IRS may request your mileage log during an audit. They look for contemporaneous records (not recreated), specific details (date, destination, purpose), and consistency with other business records. Apps with GPS tracking provide strong documentation.” }, { question: “What if my business use varies significantly year to year?”, answer: “You can choose the best method each year, subject to the rule that you must use standard mileage in year one to have the option in future years. Calculate both methods annually to maximize your deduction.” } ]} />
