How to Log Miles for Taxes Step-by-Step

October 12, 2021

Did you know that there is about 1.3 Billion Dollars unclaimed refund in the U.S. for Tax Year 2017 alone? Yours might also be there, sitting and waiting for you. If you drive a car for a business purpose, there’s a good chance you are eligible for mileage tax deduction on your federal income tax return, up to 3 years in retrospect. In this article, we’ll show you some vital points for your bulletproof business mileage deduction.

What’s Your Situation?

Whether you’re looking for a self-employed mileage deduction, you’re Reimbursing your Employees for their Business Miles, or you’re a small business owner, you need to create a vehicle mileage log for Business Tax Return. There are easier and more difficult ways to them, but first, let’s see the basic differences between the purposes of trips:

Business vs. Personal Use: What’s a business mileage?

Business Use Purposes:

  • Business Meeting / Conference
  • Driving to a Client
  • Business Lunch with a Client
  • Going to the post office, bank or Home Depot for work supplies
  • Medical purposes
  • Running business-related errands

Personal Use Purposes:

  • Commuting between home and the Company’s Headquarters
  • Doing personal shopping
  • Going to a family event
  • Driving to the cinema/theatre
  • Gym or other sport purposes

It’s vital to know that you need to track both purposes in your mileage log, so you get the ratio of business and personal trips.

Don’t run into trouble by claiming 100% business use of a vehicle at any cost. Using MileageWise’s AI-based AdWise feature, you can easily set the ratio of business and personal trips, so you get the best recommendations of forgotten trips retrospectively, auto-populated to fill in the gaps for your 100% IRS-Proof Mileage Log.

Mileage Log Step By Step

1. Standard Mileage Rate or Actual Expenses Method?

Taxpayers can select a method of calculation. Keep in mind that you cannot change the method in the same year.

  • Standard Mileage Deduction: This is the easier way, as you only need to track the number of miles you drive in a year for business purposes, then you multiply it by IRS’s Standard Mileage Rate, which is 57.5 cents in Tax Year 2020. Based on the average business miles claimed on taxes, it can add up to 12,000 per tax year. Be aware that by choosing this option, you won’t be able to deduct any operational expenses on the car (maintenance, fuel, insurance, etc.).
  • Actual Expense Method: If you feel like you can’t get the most out of standard mileage rate, you can still go with the Actual Expense Method. Although this way gives you the chance to deduct all your car expenses depending on the ratio of your business miles, it takes more time to collect all of the receipts for your repairs, registration fees, refuelings, lease payments, garage rent, depreciation, licenses, insurance, tires, tolls, and parking fees. You must choose this option if you have 5 or more cars. Remember that if you choose this method, you also have to keep copies of all the relevant documentation, such as receipts or bills.

2. Set Your Odometer Readings at Start and End of Tax Year

Are you having troubles recollecting your past odometer readings? Using MileageWise, you can easily calculate them by using our Past Odometer Reading Calculator. If you know your very first and your current odometer readings and the actual fuel consumption of your vehicle, you’re good to go.

3. Pen and paper vs. Mileage Tracker App and Web Dashboard

There are several ways to keep track of your business miles: You can create a mileage log on paper, on Google / Excel Sheet, a printable Mileage Log Template or you can use a Mileage Tracker App on your phone – sometimes accompanied by a Web Dashboard.

However, reconstructing your log on paper, especially retrospectively can be extremely difficult. There are countless fixed data and circumstances you have to keep in mind and put into your mileage log very precisely. It is a cheap solution, but at the end of the day you will certainly ask yourself: Is it worth it?

Even mileage trackers with GPS technology are inexact sometimes, because the can only track real-time driving, they cannot be used for reconstructing or creating logs retrospectively.
