How to Track Business Mileage Correctly
Business miles are money: at standard rates, every logged trip is a deduction — and every unlogged trip is a gift to the tax office. The catch is that deductions need a log: date, purpose, distance. This guide keeps that log in your browser and turns it into a claim-ready total.
Step by step
- Open the Mileage Tracker after any business trip (or at day's end).
- Enter the date, where you went and why (client name or purpose), and the miles driven.
- Set your rate per mile once — the standard rate for your country or your own figure.
- Watch the running total of deductible value build through the year.
- Export the log at tax time as your evidence file.

Tips for better results
- Log the same day. Reconstructing a year of trips in March is how deductions get abandoned.
- Record the odometer or map distance consistently — mixing methods creates gaps an auditor would find.
- Commuting to your regular workplace usually does not count; trips from there to clients and suppliers usually do. Check your local rules once.
Frequently asked questions
What must a mileage log include?
Date, destination, business purpose, and miles. That quartet is what tax authorities ask for, and this tracker captures all four.
What rate per mile should I use?
Many countries publish a standard rate (for example the IRS rate in the US). Use yours — the tracker multiplies your total miles by it.
Can I track personal miles too?
You can, marked clearly — but the value of the log is the clean business total. Keeping business trips only is simpler and safer.
