What is the purpose of your trip?

Trip Purpose

Your trip purpose is the main reason you take a journey. Recording it clearly—what you did, where you went, and why—is required for an IRS-compliant mileage log.

Understanding Trip Purpose

Think about why you’re traveling. Is it for work, leisure, to see family, or to run errands? That reason is your trip purpose.

  • Tax & Expense Tracking: Employers and the IRS require a clear business justification for each mileage deduction.

  • Data & Planning: Transportation planners use trip-purpose data to improve routes and services.

Common Trip Purposes

  • Commuting
    Travel between home and your regular workplace (not deductible).

  • Business Travel
    Trips for work beyond your usual commute—client meetings, conferences, site visits.

  • Leisure Travel
    Vacations, day trips, or any non-work enjoyment.

  • Visiting Friends or Family
    Personal, nondeductible travel to see loved ones.

  • Shopping & Errands
    Grocery runs, post office visits, and similar tasks.

  • Medical Appointments
    Doctor visits, therapy sessions, or picking up prescriptions.

  • Events
    Weddings, funerals, concerts, and other special occasions.

  • Other
    Voting, volunteering, or unique one-off reasons.

FAQ

Your trip purpose is the reason for your journey—work, personal, or medical mileage—documented to justify mileage claims and satisfy IRS requirements.

The IRS mandates a business reason for each deductible trip. Clear trip purposes (e.g. real estate showing for potential buyers) help you maximize deductions and protect you in an audit.

MileageWise prompts you to tag each trip to a new destination with a purpose when reviewing your log—choose from preset categories or enter a custom description for complete, compliant records. While apps like Stride or MileIQ require you to categorize each trip, MileageWise remembers the purpose you assigned to a client, saving you time.
