Claiming a tax deduction is one of the best ways to reduce the amount of funds owed to the government. Though the IRS tightened up the rules surrounding claiming tax on mileage, there are still other possibilities. Using two different rules—standard and actual—a tax on mileage can be claimed as a deduction. 

Throughout this article, we’ll take a closer look at business mileage, reimbursement, and the methods allowed.

What is business mileage?

The IRS defines business mileage as mileage driven between two places of work, permanent or temporary. Therefore, self-employed individuals can deduct the mileage they accrue throughout the year while doing business. All expenses can be deducted for those who use the car only for business purposes. Vehicles used for personal and business reasons will need to have business expenses separated and expensed.

Mileage tax deduction methods: standard mileage vs. actual expense

Armed with the information above, it’s possible to use one of the two methods available to deduct mileage on yearly taxes.

1. Standard mileage method 

The standard mileage method is the simpler of the two options, with the rate covering all expenses of owning and operating a vehicle for any business purpose. To claim this deduction, it’s important to keep track of the exact mileage driven and keep a record of all trips for auditing purposes. Calculating the amount is straightforward; take the mileage driven and multiply by the rate set by the IRS.

Pros and cons of the standard mileage method



Simple to calculate (multiply miles driven by IRS rate for the year)

Cannot deduct mileage on a vehicle owned by someone else

Simple to track

Cannot deduct mileage on a fleet of vehicles (5 or more)

It’s possible to switch back and forth between two methods of deducting mileage on taxes

Can only use straight-line depreciation 

Cannot claim a Section 179 deduction on the vehicle

The deduction could be lower than with the actual method

Pros and cons of the standard mileage method

2. The actual expense method

The name is rather self-explanatory for this method—only actual expenses will get deducted on taxes. The deduction is calculated by adding up all money spent on the vehicle’s operation and multiplying that by the percentage of business use. Let’s say it took $10,000 to maintain the vehicle throughout the year, but it was only used for business 50% of the time. The calculation is $10,000 x 50% = $5,000 claimed.

Pros and cons of the actual expense method



Potentially a larger deduction, especially when depreciation is factored into the equation

More records to maintain

For more expensive vehicles, there is a potential for a larger deduction

If the actual expenses method is claimed the first year, it’s not possible to flip to the standard method the next year

Larger deduction for those that don’t drive a lot throughout the year

Pros and cons of the actual expense method

Actual expenses vs. standard mileage, which is better? 

Choosing a better method will come down to personal choice rather than a hard and fast rule. Some might prefer to keep to a simpler method that provides flexibility should actual expenses prove more beneficial another year. Of course, the actual expense method does hold the potential for a higher deduction, but at the expense of keeping more records.

Frequently asked questions

What counts as business mileage?

The IRS explains that business mileage is driving done for a business purpose. This includes driving to meet clients, getting supplies, or running other errands only for the business.

How to calculate mileage reimbursement for taxes?

The calculation is simple. First, take the total miles driven and multiply the number by the rate set down by the IRS. For example—in 2023, let’s say you drove 500 miles in August. The IRS rate is 65.5 cents a mile. Therefore, 500*.0655=$32.75.

In closing

Tax on mileage is something many think about when they drive for business-related purposes. The IRS gives the ability to deduct such expenses using two methods: standard and actual expense. Each has specific pros and cons to help make the decision on which one works better. To prepare, always keep track of all expenses or miles driven using a handy tracker.
