FAQ
Should I include partial miles (like 0.3) in my log?
Yes, log every fraction of a mile—even tenths—to avoid underreporting. The IRS allows estimates only if you use a “standard mileage rate” and keep *some* records. Detailed logs (with partial miles) strengthen your case if ever audited. Rounding down is safer than up.
How far back should I keep my mileage logs?
The IRS recommends keeping logs for at least 3 years after filing taxes, in case of an audit. If you use the “actual expense” method (fuel, maintenance, etc.), logs may need to align with receipts for 6+ years. Digital files (PDF/Excel) make long-term storage easier than paper.
Can I use the same template for both business and personal trips?
No—mix personal and business miles in one log, and you’ll complicate deductions. Use separate logs or clearly mark each trip’s purpose (e.g., “Client Lunch” vs. “Grocery Run”). For leased vehicles, split logs by use type to justify reimbursements accurately. Always consult a tax pro for complex setups.
