Vehicle & Auto Expense Deduction: Mileage vs. Actual Costs
How to deduct your car for business — the standard mileage rate vs. actual expenses, what qualifies, and how to track it properly.
Quick Answer
Yes, business use of your vehicle is deductible — you choose between two methods: the standard mileage rate (67¢ per mile in 2024) or actual expenses (gas, insurance, depreciation, etc. multiplied by business-use %). You must keep a mileage log. Commuting from home to your regular workplace is never deductible — only business-purpose driving qualifies.
Standard Mileage vs. Actual Expenses
📍 Standard Mileage Rate
2024 rate: 67¢ per mile
Best for: High mileage, fuel-efficient vehicles
Tracking: Just log your miles
Simplicity: ⭐⭐⭐⭐⭐ Very easy
Note: Must choose this in the first year you use the vehicle for business
🔧 Actual Expense Method
Deduct: All costs × business-use %
Best for: Expensive vehicles, high actual costs
Tracking: All receipts + mileage log
Simplicity: ⭐⭐ More complex
Note: Can switch from standard to actual (not always vice versa)
Standard Mileage Rates by Year
| Tax Year | Business Rate (per mile) |
|---|---|
| 2024 | 67.0¢ |
| 2023 | 65.5¢ |
| 2022 (Jul–Dec) | 62.5¢ |
| 2022 (Jan–Jun) | 58.5¢ |
| 2021 | 56.0¢ |
What Counts as Business Mileage?
| Trip Type | Deductible? |
|---|---|
| Driving to client meetings | ✓ Yes |
| Travel between multiple work locations | ✓ Yes |
| Picking up supplies for your business | ✓ Yes |
| Driving to networking events | ✓ Yes |
| Delivering products to customers | ✓ Yes |
| Driving to the bank for business deposits | ✓ Yes |
| Commuting from home to your regular office | ✗ No — never deductible |
| Personal errands | ✗ No |
| Vacation driving | ✗ No |
Example: Standard Mileage Method
Total business miles driven: 12,400
2024 rate: $0.67/mile
Mileage deduction: 12,400 × $0.67 = $8,308
Plus: Tolls and parking are deductible on top of the mileage rate
Example: Actual Expense Method
Total miles driven: 18,000 | Business miles: 12,400
Business-use %: 12,400 ÷ 18,000 = 69%
Gas: $3,200 × 69% = $2,208
Insurance: $1,800 × 69% = $1,242
Repairs/maintenance: $900 × 69% = $621
Depreciation: $4,000 × 69% = $2,760
Registration: $180 × 69% = $124
Total actual deduction: $6,955
In this example, standard mileage ($8,308) wins. Always run both.
The Mileage Log Requirement
The IRS requires contemporaneous records — meaning you track mileage at or near the time of each trip, not from memory at year end. Your log must include: date, destination, business purpose, and miles driven. A mileage tracking app (MileIQ, Everlance, Stride) makes this effortless and creates IRS-ready records automatically.
How to Claim Vehicle Deductions
- Choose your method — standard mileage or actual expenses
- Keep a mileage log for every business trip all year
- For actual expenses: save all receipts (gas, insurance, repairs, registration)
- Self-employed: Report on Schedule C, Part II, Line 9
- For depreciation under actual method: complete Form 4562
- Tolls and parking are always deductible separately, regardless of method
Tips for Maximizing Your Vehicle Deduction
Use a mileage tracking app from day one — MileIQ, Everlance, and Stride automatically log trips using your phone’s GPS. They categorize business vs. personal with a swipe. Year-end reports are generated automatically. This is the single best thing you can do for vehicle deduction documentation.
Run both calculations before filing — The better method changes based on your vehicle, mileage, and costs. High-mileage years favor standard rate. Expensive vehicles with high actual costs may favor the actual method. Your tax software or CPA can run both.
Don’t forget tolls and parking — Tolls and parking fees for business trips are deductible on top of your mileage rate — they’re not included in the 67¢/mile calculation. Many people miss these small but real deductions.
Home office + vehicle = powerful combo — If you have a qualified home office, your home becomes your principal place of business. This means driving from home to any client, supplier, or business location counts as deductible business mileage — not commuting.
Common Questions
Can I deduct a vehicle I use for both business and personal?
Yes — you deduct only the business-use portion. With the standard mileage method, you only count business miles. With actual expenses, you multiply all costs by your business-use percentage. You cannot deduct personal driving regardless of method.
Can I deduct a leased vehicle?
Yes. For leased vehicles, the standard mileage rate works the same way. Under actual expenses, you deduct the lease payment multiplied by business-use percentage, instead of depreciation. There’s also a “lease inclusion amount” that reduces your deduction slightly for expensive leased vehicles — your tax software handles this automatically.
What about a vehicle used 100% for business?
If you have a vehicle used exclusively for business — never for personal use — you can deduct 100% of costs. However, the IRS scrutinizes 100% business-use claims closely, especially for vehicles that could easily be used personally. Solid mileage log documentation is essential.
