Tax season comes just once a year, but it takes significant organization each month to prepare. For self-employed individuals, in particular, the process of gathering documentation and maintaining accurate reports is especially important. If you plan to take the mileage deduction, home office deduction, or other eligible tax write-off, you’ll need substantial proof to back your claims. 

In this guide, we will focus our attention to the mileage deduction, explaining the step-by-step process of claiming mileage on taxes.

5 steps to claiming mileage from the IRS

Step #1: Choose a method

When it comes to claiming car-related expenses, the IRS gives taxpayers two options for calculating potential tax savings: the standard mileage rate or actual expense method. 

The standard mileage rate involves tracking your mileage for business purposes throughout the tax year. You can maintain records manually, or use an automatic mileage tracking app to document your drives. When it’s time to file your taxes, you simply multiple the total number of business miles driven by the IRS standard mileage rate. The IRS rates for 2025 are:‍

• 70 cents per business mile (up 3 cents from 2024). 
• 21 cents per mile driven for medical or moving purposes for qualified active-duty members of the Armed Forces (unchanged from 2024).
• 14 cents per mile driven in service of charitable organizations (unchanged from 2024).
• Employers can also set their own mileage rate; however, the figure should not exceed the IRS standard mileage rate.

The actual expense method is another way to claim the use of an automobile for business purposes, but it requires eligible taxpayers to track the total money spent on the business use of their vehicle. If you choose this method, you must deduct operating costs, including depreciation, licensing, insurance, gas, repairs and maintenance.

• You can only deduct the business-use of your vehicle. That means, you must compute the percentage of time you use your car for work-related purposes. 
• For example, if it costs you $4,000 to operate your vehicle in a given year, and you used your car 60% of the time for business purposes, then you could deduct $2,400 on your tax return. ($4,000 vehicle costs x 60% business use)

Step #2: Gather documentation

It’s fair to mention this is one of the most important steps in claiming mileage from the IRS. Not only do accurate records keep your tax information well-organized, it also helps you avoid any IRS audits down the road. 

With the standard mileage rate, it’s imperative to maintain a logbook of all your business drives. One of the easiest ways of doing this is by signing up for an automatic mileage tracking app. Every time you drive to a job site or run a business errand, the app will run in the background of your phone and create accurate logs of your mileage. 

Alternatively, in the chance it is more beneficial to deduct actual expenses, you’ll need to keep receipts, digital invoices, and any documentation that backs your deduction claims. To illustrate, if you have a repair done on your vehicle, you must keep the receipt for your future tax filing.
