The Legend of the Missing Mileage Log: A Cautionary Tale from the Road

Once upon a summer road trip, a business owner set out with good intentions: track every mile, log every client visit, and deduct like a champ come tax time. But somewhere between the gas station snacks and the podcast bingeing… the mileage log vanished. Poof. Gone. Lost to the winds of poor record-keeping.

Don’t let this be your story.

1. Why Mileage Matters

If you use your vehicle for business, every mile you drive could be a deduction—fueling serious savings at tax time. But the IRS doesn’t go by vibes. You need documentation to back up those miles.

2. Paper or Pixel: Pick Your Weapon

Whether you’re old-school with a glovebox notebook or app-savvy with a tracker like MileIQ or Everlance, the best tool is the one you’ll actually use. Log the date, destination, purpose, and miles. That’s it.

3. Don’t Mix Personal with Business

A mileage log is not a diary of your Costco runs. Keep your personal and business drives clearly separated. The IRS likes clean lines, not creative math.

4. What Happens If You Don’t?

Without proper documentation, your mileage deduction could vanish faster than a dropped French fry between the seats. If audited, the IRS can—and will—deny the entire deduction. That hurts.

5. Turn Logging Into a Habit

Try logging miles daily or weekly—whatever keeps you consistent. Pair it with another habit, like checking email or setting your GPS. It’s like brushing your financial teeth.

Keeping a mileage log might not feel like a grand adventure—but it’s one of the easiest ways to protect your bottom line. A few extra minutes each week can translate into hundreds (or even thousands) of dollars saved at tax time. So document the journey, one mile at a time—and let your deduction ride off into the sunset with confidence.
