One trip has an end reading below its start reading. It is excluded from the total.
Odometer readings, not estimates
The difference between two odometer readings is a fact. An estimate is an opinion, and an examiner treats it as one. That is why the IRS asks you to substantiate mileage rather than simply assert it.
Readings must also be continuous. If one trip ends at 42,110 and the next starts at 42,400, those 290 miles were driven — and, undocumented, they count as personal.
Which miles count
Business miles are the ones driven between places of business: client to client, office to site, home office to client. The drive from home to a regular workplace is a commute and never counts, no matter the distance.
The 2026 business rate is 70 cents per mile. The medical, moving and charitable rates differ, and are listed on the IRS mileage rate 2026 page.
Next steps
To work from a total you already know, use the mileage reimbursement calculator. To record trips as you drive them, start from the free mileage log template.
Typing odometer readings into a spreadsheet is the part everyone abandons by March. Kilevo reads your Google or Outlook calendar, turns appointments into trips, computes the distance between the addresses, and exports the year as a single report.
