Frequently asked questions
- What has to be in a mileage log for the IRS?
- Four things per trip or per day: the date, the business purpose, the miles driven, and your total annual mileage. Odometer readings at the start and end of the year support the total. A spreadsheet, notebook or app all qualify as long as the entries are made close to the time you drove.
- Does a weekly summary count, or do I need every trip?
- The IRS accepts a log kept at reasonable intervals, so daily totals with the business purpose noted are acceptable. Reconstructing a whole year from memory in April is what gets deductions disallowed on audit.
- Can I just use my platform's mileage report?
- Use it as support, not as your log. Platform reports usually miss app-on waiting miles and the drive to your first accepted job, so they understate the deduction. Keep your own record and reconcile it against the platform total.
- What is the 2026 standard mileage rate?
- The IRS business standard mileage rate for 2026 is $0.70 per mile. It covers gas, maintenance, insurance, tires and depreciation, so you do not deduct those separately when you use it.
- How long do I keep the log?
- At least three years after filing the return that uses it, which is the normal audit window. Many drivers keep seven years of records because vehicle depreciation and prior-year amendments can reach back further.
- Can I switch between logging apps mid-year?
- Yes. Export the earlier data so the year is continuous, then keep both exports. What matters is that the full year is covered by contemporaneous records, not that they came from one tool.
