Quick Answer
Yes, you can deduct the business portion of a mixed-use vehicle. If you drive 15,000 business miles out of 25,000 total miles (60% business use), you can deduct 60% of vehicle expenses or use the standard mileage rate of $0.70 per business mile for 2026.

Anyone who uses their personal vehicle for both business and personal trips
Yes, you can deduct the business portion of any vehicle
The IRS allows you to deduct vehicle expenses based on the percentage of business use — even if you also use the car for personal trips. The key is accurately tracking your business vs. personal mileage throughout the year.
You have two methods to calculate the deduction: standard mileage rate or actual expenses. For 2026, the standard mileage rate is $0.70 per business mile.
Example: Freelance graphic designer's mixed-use car
Sarah drives her 2024 Honda CR-V for both client meetings and personal errands:
Standard mileage method:
12,000 business miles × $0.70 = $8,400 deduction
Actual expense method:
Sarah would choose standard mileage ($8,400) because it's higher.
How to determine business use percentage
What records you need to keep
The IRS requires "adequate records" showing:
Use a mileage app or simple logbook. Track for the full year — the IRS may audit and request complete records.
Key rules to remember
What you should do
1. Start tracking immediately — use our expense-tracker tool or a mileage app
2. Calculate both methods at year-end to see which gives a higher deduction
3. Keep detailed records — date, mileage, business purpose for every trip
4. Consider actual expenses if you have high car payments or drove fewer miles
Use our deduction-finder tool to compare standard mileage vs. actual expense methods based on your specific situation.
Key takeaway: You can deduct the business percentage of any mixed-use vehicle, but you must track actual business miles and maintain detailed records to support your deduction.

Drivers who use their personal vehicle for both gig work and personal trips
Mixed-use vehicles for rideshare drivers
As a former rideshare driver, I know most of us use our personal car for both driving and regular life. The good news: you can absolutely deduct the business portion, and for most drivers, that's a substantial deduction.
Real example: Part-time Uber driver
Mike drives Uber 20 hours/week and uses his car personally too:
Standard mileage deduction: 18,000 × $0.70 = $12,600
This saves Mike about $2,500-$3,500 in taxes depending on his bracket.
What counts as business miles for drivers
What doesn't count:
Why standard mileage usually wins for drivers
Most rideshare drivers should use standard mileage because:
The apps track your business miles automatically, making record-keeping simple.
Key takeaway: Rideshare drivers can deduct business miles even from personal vehicles, with standard mileage typically providing $0.70 per mile driven for work.

W-2 employees with side freelance work who occasionally use their car for business
Vehicle deductions for occasional business use
If you're a W-2 employee with a side hustle that occasionally requires driving, you can still deduct those business miles — even if it's a small percentage of your total driving.
Example: Weekend photography side hustle
Jennifer works full-time in marketing and does wedding photography on weekends:
Deduction calculation:
2,000 business miles × $0.70 = $1,400
Tax savings at 22% bracket: $1,400 × 22% = $308
Even small business use can provide meaningful tax savings.
When actual expenses might make sense
For side hustlers with low mileage but expensive cars, consider actual expenses:
Example: If you have a $800/month lease payment but only drive 8,000 total miles (1,500 business), actual expenses might give: ($800 × 12 + insurance + gas) × 18.75% business use.
Simple tracking for side hustlers
Since your business use is occasional:
Remember: the IRS can audit and request detailed records, so track every business trip even if it seems small.
Key takeaway: Even occasional business use of personal vehicles is deductible — track every business trip to maximize your side hustle tax savings.
Key Takeaway: Even occasional business use of personal vehicles is deductible — track every business trip to maximize your side hustle tax savings.
