If you're self-employed, the mileage deduction is one of the most valuable tax breaks available to you — and one of the most under-claimed. In 2026, every business mile you drive is worth $0.70 in deductible expenses, which directly reduces both your income tax and your self-employment tax.
This guide covers everything: which miles qualify, how to track them correctly, how to claim the deduction, and how to maximize your write-off legally.
How Big Is the Self-Employed Mileage Deduction?
Here's a concrete sense of what this is worth in 2026:
| Annual Business Miles | Deduction | Est. Tax Savings* |
|---|---|---|
| 5,000 miles | $3,500 | ~$1,225 |
| 10,000 miles | $7,000 | ~$2,450 |
| 15,000 miles | $10,500 | ~$3,675 |
| 20,000 miles | $14,000 | ~$4,900 |
| 30,000 miles | $21,000 | ~$7,350 |
*Estimated savings assuming 35% combined income + SE tax rate. Your actual savings depend on your tax bracket.
Which Miles Count as Business Miles?
The IRS defines business miles as travel that is "ordinary and necessary" for your trade or business. For most self-employed people, qualifying trips include:
- Driving to meet clients or customers
- Traveling between two business locations (e.g., client A to client B)
- Going to a temporary work site (not your regular place of business)
- Bank trips for business deposits
- Picking up supplies or equipment for your business
- Driving to a professional development seminar or conference
- For gig workers: every mile driven while actively working (Uber, DoorDash, etc.)
Miles That Don't Qualify
- Commuting: Driving from your home to your regular office — even if you're self-employed and the "office" is a client's location — is generally considered personal commuting
- Personal errands mixed with business: If you stop for groceries on the way to a client, only the business portion counts
- Driving to a second job: Not deductible as a business expense for that second job
If your home qualifies as your principal place of business (you have a dedicated home office used regularly and exclusively for work), then ALL driving from home to any business location is deductible — including what would otherwise be a commute.

The IRS requires a contemporaneous written record — meaning you log trips as they happen, not reconstructed later from credit card statements or memory. Your log must include for each trip:
- Date
- Starting point and destination
- Business purpose
- Miles driven
You also need to track your total vehicle miles for the year (to establish the business-use percentage) — your odometer reading on January 1 and December 31 is the easiest way to capture this.
Best Ways to Track Mileage
- Mileage tracking app: MileIQ, Everlance, Stride — automatically detect trips via GPS, you just swipe to classify as business or personal
- Our free mileage log: Use MileageReimburse's mileage log generator to create and print an IRS-compliant log
- Spreadsheet: Simple and effective. A Google Sheet with date, from, to, purpose, miles columns is perfectly acceptable
How to Claim the Deduction on Your Tax Return
Self-employed individuals claim vehicle expenses on Schedule C (Form 1040), Part II, Line 9 — Car and Truck Expenses. You'll also need to complete Part IV of Schedule C (Information on Your Vehicle), which asks for:
- Date the vehicle was first used for business
- Total miles driven during the year
- Business miles for the year
- Whether you have written evidence to support the deduction (mileage log)
The deduction flows through Schedule C to reduce your net self-employment income. That lower income reduces both your federal income tax and your self-employment tax on Schedule SE.
Standard Mileage Rate vs. Actual Expense Method
You have two options for calculating your deduction:
- Standard mileage rate ($0.70/mile): Simpler, requires only a mileage log. Best for fuel-efficient vehicles or high-mileage driving.
- Actual expenses: You track every vehicle cost (gas, insurance, maintenance, registration, depreciation) and multiply by the business-use percentage. Better for expensive vehicles with high depreciation.
Important: You must choose the standard mileage rate in the first year the vehicle is available for business use. You cannot switch to the standard rate after using MACRS depreciation. Run the numbers both ways in your first year to see which is better for your situation — or ask your CPA.
Quarterly Taxes and Mileage
If you're self-employed, you pay estimated taxes quarterly. Your mileage deduction directly lowers your estimated tax bill. If you're deducting $10,000+ in mileage annually, you should factor that into your quarterly payment calculations to avoid overpaying.
