Let’s start with the foundations:

Why keeping track of your mileage is important

It’s crucial to keep track of your mileage if you drive, period. This provides you with a better understanding of your fuel usage so you can plan how to use your car more effectively. Your car’s fuel consumption in relation to its miles will show whether it is still as fuel-efficient as it once was or whether a repair is needed.

Additionally, keeping track of your miles is essential for tracking your auto insurance, especially if you have a mileage-based policy. Tracking your mileage enables you to know whether to get a top-up or when to drive less so you don’t go over your limit because the premium for pay-per-mile vehicle insurance is based on how much you drive.

And last, but not least, if you’re driving your car for business and looking to deduct your vehicle-related expenses, you’re gonna need a simple & acceptable mileage log with the trips you tracked or logged, which can be kept in several different ways.

What information to include in your vehicle mileage log book

The IRS’s mileage log requirements are:

  • The date of each travel
  • The purpose for each travel (business or personal) – NOTE: an automatic mileage tracker app like MileageWise auto-categorizes these trips
  • The addresses of your starting and ending points (including zip codes)
  • The total amount of miles you drove
  • Odometer readings

NOTE: The IRS only requires the annual starting and ending odometer readings. However, If you’re working as an employee, tracking your miles for mileage reimbursement, your employer might need your odometer readings more often – it’s a matter to discuss for sure. If you need a retrospective mileage log but don’t have your past odometer readings, just use our Odometer Reading Calculator.

What should I do with personal trips?

Although the IRS doesn’t require personal trips in your mileage log, it’s strongly recommended that you include them because it will provide clarity for both yourself and the IRS, since you need to separate your total business mileage, total personal mileage, and total commuting mileage for the year.

Also, logging your personal trips boosts the proficiency of MileageWise’s built-in IRS auditor function, which you need for an IRS-Proof result.

Use your car’s odometer

Your car’s dashboard is equipped with an odometer, which is a device that counts the miles you’ve driven. The odometer in your car is either mechanical or digital, depending on its age. Although it seems trustworthy, your odometer may be readily reset at any time, which could mess with your maintenance and auto insurance plans. By indicating the mileage cap on the car window decal sticker, you may avoid this issue.

Use Google Maps Timeline as a mileage log backup

What to do with your mileage logs at tax time

The supporting documentation for a mileage deduction must be kept for at least three years. Make a copy of the records and file a personal copy if the IRS requests to view the paperwork to support the mileage deduction. For each tax year, make a new log to keep everything organized.
