📒 Keep a mileage log. The IRS requires a contemporaneous record — date, destination, business purpose, and miles for each trip. Reconstructed or estimated logs are routinely disallowed on audit. A tracking app or a notebook kept all year is your best protection.
Educational estimate only — not tax advice. The standard mileage rate has eligibility rules (e.g., you must use it the first year a vehicle is placed in service to switch later). See IRS Pub. 463 and confirm with a tax professional.
