If you drive for your business — visiting clients, delivering products, traveling between job sites — the IRS lets you deduct the cost of that driving as a business expense. Two methods exist: the standard mileage rate and actual vehicle expenses. The method you choose in the first year you use a vehicle for business generally locks you in for that vehicle.
Which vehicles qualify for a business deduction
Any passenger vehicle, van, pickup truck, or panel truck used for business qualifies. Commuting — driving from your home to your regular place of business — is never deductible, regardless of method or vehicle type.
Business use includes driving to client meetings, picking up supplies, visiting job sites, and traveling between business locations. If you use a vehicle for both personal and business purposes (which most self-employed filers do), only the business-use percentage is deductible. If you drove 15,000 miles total and 10,000 were for business, your deductible percentage is 67%.
Method 1: The standard mileage rate
The IRS business standard mileage rate for 2026 is 72.5 cents per mile, up 2.5 cents from 70 cents in 2025. The rate is designed to cover average fuel, oil, maintenance, insurance, and depreciation — packaged into a single number so you do not need to track individual expenses.
How to calculate: Multiply verified business miles by the rate.
10,000 business miles × $0.725 = $7,250 deduction
Key restrictions per IRS Topic 510:
- You must elect the standard rate in the first year the vehicle is placed in business service. If you claim actual expenses in year one, you cannot switch to the standard mileage rate later.
- For a leased vehicle, electing the standard rate locks you in for the entire lease period, including renewals.
- You cannot use the standard rate if you claimed Section 179 or bonus depreciation on that vehicle, or if you operate five or more vehicles simultaneously for business.
Parking fees and tolls paid on business trips are separately deductible on top of the standard rate — they are not built into the per-mile amount.
Method 2: Actual vehicle expenses
The actual expense method lets you deduct the real operating costs of the vehicle multiplied by your business-use percentage. Deductible costs include:
- Fuel and oil
- Auto insurance
- Registration and license fees
- Repairs and maintenance
- Tires
- Lease payments (if leased)
- Depreciation (if owned)
Depreciation is where the actual method can create a significant first-year advantage. Under the One Big Beautiful Bill, 100% bonus depreciation is permanently restored for qualifying property placed in service after January 19, 2025. In year one, you may be able to write off the full business-use portion of a qualifying vehicle's cost.
Two limits apply:
- Passenger autos (IRC §280F): The IRS caps annual depreciation on standard passenger cars regardless of bonus depreciation. IRS Publication 463 lists the current-year dollar ceilings.
- Heavy SUVs and trucks (GVWR over 6,000 lbs): Subject to a Section 179 expensing cap rather than the passenger-auto limits — generally more favorable for first-year expensing on qualifying heavy vehicles.
The actual method requires receipts for every expense and a mileage log showing the business percentage of total use.
How to choose: standard vs. actual
Run both calculations with your actual numbers. The method generating the larger deduction wins — subject to the first-year restriction for owned vehicles.
| Situation | Favors |
|---|---|
| Fuel-efficient vehicle, moderate miles | Standard mileage |
| Heavy truck or SUV in first year of service | Actual (bonus depreciation) |
| Very high annual business miles | Standard mileage (scales linearly) |
| Vehicle with high repair or maintenance costs | Actual expenses |
| Leased vehicle | Actual may be better (no §280F depreciation cap) |
| Simplicity, minimal recordkeeping | Standard mileage |
CPAs typically model both scenarios for a new business vehicle because the first-year depreciation advantage of the actual method is largest when the vehicle is new. After year one, depreciation decreases and the standard rate often becomes competitive.
The recordkeeping requirement
The IRS requires a contemporaneous mileage log — recorded as you drive, not reconstructed months later. Per IRS Publication 463, each entry should include:
- Date of each business trip
- Odometer reading at start and end (or miles driven)
- Destination and business purpose
A mileage-tracking app or a simple spreadsheet both satisfy the requirement. Bank statements and calendar records can corroborate a log but do not replace it. Inadequate records are the primary reason vehicle deductions are disallowed on audit. Claiming 100% business use of a vehicle you also drive personally is one of the most common audit triggers for self-employed filers — document the personal/business split carefully.
High deductions making your tax return look lean?
ClearValue Lending's lender partners underwrite on bank statement cash flow — not just what survives Schedule C deductions. Your actual business revenue drives the conversation.

Vehicle deductions reduce net profit on Schedule C — the income figure lenders see on tax returns. A contractor who drove 22,000 business miles and claimed a $15,950 deduction sees that subtracted from Schedule C net income. Lower net income on paper can make qualifying for traditional bank financing harder, even when business cash flow is healthy.
ClearValue Lending's lender partners underwrite primarily on bank statement cash flow, not Schedule C net income. If legitimate deductions make your tax return look leaner than your revenue, bank-statement underwriting credits the business for what it actually generates. Review your bank statements alongside your return before applying — what underwriters actually look for on tax returns explains exactly how lenders parse the numbers.

FAQ
Can I deduct mileage on my personal car used for business?
Yes. The IRS does not require a dedicated business vehicle. You can deduct the business-use portion of your personal car using the standard mileage rate (72.5 cents per mile in 2026) or actual expenses. Track business miles separately from personal miles and document each trip with a destination and business purpose.
What if I forgot to track mileage during the year?
Reconstruct what you can from calendar entries, client billing records, bank statements, and GPS history. A reconstructed log is better than nothing, but the IRS prefers records kept at the time of each trip. Going forward, a mileage-tracking app logs trips automatically and provides audit protection.
Can I deduct parking and tolls in addition to the standard mileage rate?
Yes. Parking fees and tolls paid on business trips are separately deductible on top of the standard rate — not included in the 72.5 cents per mile. Parking at your regular workplace is commuting and is not deductible.
Can a sole proprietor claim the vehicle deduction on Schedule C?
Yes. Vehicle expenses are reported on Schedule C Part II, Line 9. Depreciation under the actual expense method also requires Form 4562. For the standard mileage method, a mileage log is the supporting document. Both methods require showing total miles and business miles separately.
What is the IRS standard mileage rate for 2026?
The 2026 business standard mileage rate is 72.5 cents per mile, per IRS Notice 2026-10, effective January 1, 2026 — up 2.5 cents from 70 cents per mile in 2025. The IRS adjusts the rate annually; check the standard mileage rates page for future years.
