Requirements for a Valid Log
A valid IRS mileage log must record the date, destination, business miles, and business purpose for every trip. To ensure accuracy, you should update your records at least weekly.

Standard Mileage Rates
For 2025, the IRS standard mileage rate is 70 cents per mile. You must elect the standard mileage rate in the first year a car is used for business.
Looking ahead, the IRS 2026 rate is 72.5 cents per mile. For Canadian taxpayers, the 2025 CRA rate is $0.72/km for the first 5,000 km and $0.66/km thereafter.
Automating Your Mileage Log
Manual logging is prone to error. TradesTimer uses background GPS to automatically detect 'stops' (jobsites) and 'trips' (driving between them).
It records the distance for every trip, providing a rounded mileage log you can export at tax time. There are no timers to start or stop and no jobsites to pre-configure.
