Can I reconstruct a mileage log at the end of the year?
The Risk of Year-End Reconstruction
The IRS requires a valid mileage log to be kept contemporaneously, meaning you should record your business miles, date, destination, and business purpose at or near the time of the trip. Waiting until year-end to 'reconstruct' your driving from memory is highly susceptible to audit challenges.
Reviewing your records weekly at a minimum ensures accuracy and prevents missing small trips that add up over time.
Automating Your Log with TradesTimer
TradesTimer removes the burden of manual entry. The app runs in the background and automatically detects 'stops' at jobsites and 'trips' between them.
Because it records the distance for every trip, it builds a mileage log for you throughout the year. You can simply export this data at tax time without ever having to manually start or stop a timer or pre-configure jobsites.
Verified Mileage Rates
For your 2025 tax filings, the IRS standard mileage rate is 70 cents/mile. For 2026, the rate increases to 72.5 cents/mile.
