Let’s be real — tracking mileage isn’t the most glamorous part of running a business, but it is one of the easiest ways to save money on your taxes. That is, if you do it right. If you’re claiming mileage as a business expense, the IRS requires proof. No log, no deduction. It’s that simple. Here’s what you need to know:
What Actually Counts as a Mileage Log?
To satisfy the IRS, your mileage log must include:
- Date of the trip
- Starting point and destination
- Purpose of the trip
- Number of miles driven
What Doesn’t Count as Business Mileage?
Not all driving is deductible. Here are a few examples of trips that don’t make the cut:
- Commuting – Driving from your home to your regular workplace is not deductible.
- Personal errands during a business trip – Stopping for groceries or picking up your kid from school while out for a client meeting doesn’t count.
- Trips with no clear business purpose – If you can’t explain why it helped your business, leave it off.
Rule of thumb: if the drive wasn’t necessary for your business, it’s not deductible.
How to Track It (Without Losing Your Mind)
You’ve got options:
Old School:
- Paper logbook – It works, but only if you’re consistent. Keep it in your car and write down every trip as you go.
Digital Options:
- Apps like MileIQ, Everlance, or TripLog – These use GPS to track your trips automatically and let you categorize them with a swipe. Game changer.
- Google Sheets or Excel – If you want a DIY option but still want it digital, create a simple spreadsheet with the required fields.
Final Word: A Little Effort = Big Savings
Tracking your mileage might feel tedious, but it’s money on the table if you skip it. In 2025, the IRS standard mileage rate is 70 cents per mile, so every mile you track adds up fast. A few extra minutes a week can mean hundreds or even thousands off your tax bill. Pick a method that works for you, and start logging those miles like the savvy business owner you are.
