What Counts as Business Mileage

✅ Deductible Business Mileage

Client/customer visits:

• Driving to client offices
• Meeting clients at coffee shops
• Site visits
• Sales calls

Business errands:

• Office supply runs
• Bank deposits
• Post office for business mail
• Equipment pickup

Travel between work locations:

• From home office to client site
• From one client to another
• From home office to coworking space

Business travel:

• Driving to airport for business trip
• Rental car during business trip
• Driving to business conference

Special situations:

• Driving for gig work (Uber, DoorDash, etc.)
• Real estate showings
• Contractor work between job sites

❌ Not Deductible

Commuting:

• Home to regular office (fixed location)
• Home to same coworking space daily

Personal errands:

• Grocery shopping (even during work hours)
• Doctor appointments
• Personal travel

Mixed trips (without allocation):

• Business meeting then grocery store
• Must allocate if purpose is mixed

The Commuting Exception

If you have a home office that qualifies as your principal place of business, driving FROM your home office TO clients or other work locations is deductible (not commuting).

Without home office:

Home → Client Office = Commute (not deductible)

With qualifying home office:

Home Office → Client Office = Business travel (deductible)

Two Methods: Standard vs. Actual

Method 1: Standard Mileage Rate

The simple approach. Multiply business miles by the IRS rate.

2026 Calculation:

Business miles × 0.67 = Deduction
10,000 miles × 0.67 = 6,700

What it includes:

• Gas
• Oil changes
• Repairs
• Insurance
• Depreciation (built into rate)
• Registration

What you add separately:

• Parking fees (business)
• Tolls (business)
• Interest on car loan (business portion)

Requirements:

• Must choose this method in first year of business use
• Own or lease the vehicle
• Not using 5+ vehicles simultaneously
• No depreciation method other than straight-line previously

Method 2: Actual Expenses

Track all vehicle costs, deduct the business percentage.

Step 1: Track all vehicle expenses

• Gas
• Oil changes
• Repairs & maintenance
• Insurance
• Registration
• Depreciation
• Lease payments
• Loan interest

Step 2: Calculate business percentage

Business miles ÷ Total miles = Business %

Step 3: Apply percentage

Total vehicle expenses × Business % = Deduction

Example:

Total 2026 driving: 15,000 miles
Business driving: 10,000 miles
Business percentage: 66.7%

Vehicle expenses:
Gas: 3,400
Insurance: 1,800
Repairs: 1,200
Depreciation: 3,000
Registration: 300
Total: 9,700

Deduction: 9,700 × 66.7% = 6,470

Which Method Is Better?

Calculate both and compare!

Standard mileage wins if:

• You drive an older, paid-off vehicle
• Your car is fuel-efficient
• You don't have high maintenance costs

Actual expenses win if:

• You drive a new, expensive vehicle
• You have a car payment
• Your car has high depreciation value

IRS Mileage Log Requirements

The IRS requires a contemporaneous record—meaning logged at or near the time of the trip.

Required Information

For each trip, record:

1. Date of the trip
2. Destination (where you went)
3. Business purpose (why—client meeting, supply run, etc.)
4. Miles driven (odometer readings or GPS tracking)

What a Valid Log Looks Like

| Date | Destination | Purpose | Miles | |------|-------------|---------|-------| | 1/15/26 | Acme Corp, 123 Main St | Client meeting re: Q1 project | 24 | | 1/15/26 | Office Depot | Printer supplies | 6 | | 1/17/26 | Downtown Bank | Business deposit | 14 | | 1/18/26 | Blue Coffee, Oak St | Client meeting - new proposal | 8 |

What's NOT Sufficient

❌ "Various business trips - 500 miles" (no details) ❌ Year-end reconstruction from memory ❌ Estimate without tracking ❌ Bank statements showing gas purchases (no mileage proof)

Mileage Tracking Best Practices

1. Choose Automatic Tracking

Manual tracking fails. You forget trips, lose accuracy, and underestimate.

Apps with automatic detection capture trips you'd forget to log.

2. Classify Daily

Don't wait until year-end. Take 30 seconds at end of each day to classify the day's trips.

3. Be Specific on Purpose

Too vague: "Business" Better: "Client meeting - Review Q1 marketing plan"

If audited, specific purposes are more credible.

4. Include Parking and Tolls

These are deductible on top of mileage. Track them separately:

• Date, location, amount
• Photos of parking receipts
• Toll records (EZ-Pass statements work)

5. Keep Backup Records

Even with an app:

• Screenshot monthly summaries
• Export to PDF quarterly
• Save to cloud storage

6. Separate Business and Personal Correctly

When in doubt, don't claim it. An overly aggressive log is worse than a conservative one.

Special Situations

Mixed Trips

If a trip has both business and personal purposes:

Primarily business: Deduct the whole thing if you wouldn't have made the trip without the business purpose.

Mixed purpose: Only deduct the business portion.

Example:

Drive to client (10 miles) → Grocery store (2 miles) → Home (8 miles)

Deductible: 10 miles (to client)
Not deductible: 10 miles (grocery and home)

Gig Workers (Uber, DoorDash, etc.)

Deductible:

• From first pickup to last dropoff
• Driving to first pickup (from home or between apps)
• Waiting for rides (if you're available)

Not deductible:

• Driving home when app is off
• Personal errands during shift

Multiple Vehicles

You can use different methods for different vehicles:

• Standard mileage on Car A
• Actual expenses on Car B

Helpful if one vehicle is more expensive to operate.

Leased Vehicles

Standard mileage or actual expenses both available, but once you choose actual expenses with a lease, you're locked in for that lease.

Mileage Audit Protection

IRS Scrutiny Points

The IRS knows:

• Average business mileage by industry
• Typical commuting patterns
• Red flags (round numbers, no log)

How to Protect Yourself

1. Contemporaneous log — Record in real-time, not year-end
2. Specific purposes — "Acme Corp meeting" not "business"
3. Reasonable totals — Consistent with your business type
4. Backup documentation — Calendar entries, client emails
5. No round numbers — 10,247 miles is more credible than 10,000
