Record the trip while the details are fresh
A useful entry explains why the journey happened, not just where it ended. “Client A, project inspection” is more informative than “business.” If you enter only a distance, keep enough supporting context to explain how you obtained it. Do not present a reconstructed estimate as a contemporaneous odometer reading.
For US tax records, IRS Publication 463 describes supporting the amount, time, place or destination and business purpose, along with vehicle-related records. It recognizes computer records and discusses timely recordkeeping. This article is a record-design guide, not a determination of tax eligibility. Rules in other countries and employer policies can differ.
A worked distance example
| Date | Vehicle | Start | End | Distance | Route | Purpose |
|---|---|---|---|---|---|---|
| 2026-10-05 | Example car | 42,180 mi | 42,198 mi | 18 mi | Office → client → office | Client A project visit |
End odometer minus start odometer gives 18 miles in this example. If a route includes a personal detour, preserve the distinction rather than treating the whole movement as work. Keep the unit visible: kilometers entered into a miles-based reimbursement calculation produce an incorrect amount.
For an illustration only, an employer-agreed rate of $0.50 per mile would give 18 × $0.50 = $9.00. This is an arbitrary example rate, not the current IRS rate or a recommended employer rate. Use the actual policy and its effective date when you calculate a real amount.

“Business,” “commute” and “personal” are record categories, not interchangeable tax conclusions. Normal commuting can be treated differently from qualifying business travel. Consult the relevant rules for your situation rather than marking all travel to work as a claim.
Reimbursed is another separate fact. A recorded work trip may not yet be submitted or paid. Keep the submission date, paid amount and reference when you need to reconcile employer payments. If client travel is billable, transfer only the agreed amount to the invoice and keep the trip evidence.
A weekly review that catches mistakes
- Look for missing dates, mixed units and ambiguous purpose notes.
- Check start and end readings and investigate overlaps or impossible distances.
- Separate personal detours and commuting according to the applicable rules.
- Match submitted reimbursements to the right trips.
- Keep original supporting records and a recoverable export.
Annual reporting may need more than the business-trip rows: for example, total vehicle mileage and other supporting information. Consult the relevant year’s guidance or your adviser. A good log does not remove the need to show the basis of your claim.
Keep service mileage in a maintenance log when maintaining an RV; do not confuse a service-history odometer with a list of work journeys. For paid shows, the venue advance packet can provide context, but it is not a replacement for trip records.
Manual tracking versus automatic location tracking
OdoCue’s current listing describes manual trip entry, vehicle and purpose categories, odometer or direct-distance entry and report totals. It does not require GPS trip tracking. That approach suits people willing to record journeys themselves; it cannot automatically recover journeys you forgot to enter.
Premium includes CSV and PDF exports, yearly reports and reimbursement summaries. Keep a separate recoverable copy and verify that an export contains the fields you need. A generated report is not “IRS approved” and does not guarantee reimbursement. Check current in-app terms before subscribing.

This CSV is a manual record, not an automatic GPS tracker or tax-eligibility calculator. Distance = end odometer − start odometer in one consistent unit. Recalculate changed examples.
Questions answered
Do I need GPS tracking to keep a mileage log?
No. A manual log can record trips, but you must enter reliable details and retain the supporting evidence required for your purpose.
Is every trip to work deductible?
No. Commuting and qualifying business travel can have different treatment. Check the rules for your situation.
Does OdoCue automatically record missed journeys?
No. Its current listing describes manual mileage entry without GPS tracking.
