The standard business mileage rate increases for 2023

Although the national price of gas is a bit lower than it was a year ago, the optional standard mileage rate used to calculate the deductible cost of operating an automobile for business will be going up in 2023. The IRS recently announced that the 2023 cents-per-mile rate for the business use of a car, van, pickup, or panel truck is 65.5 cents. These rates apply to electric and hybrid-electric automobiles, as well as gasoline and diesel-powered vehicles.

In 2022, the business cents-per-mile rate for the second half of the year (July 1 – December 31) was 62.5 cents per mile, and for the first half of the year (January 1 – June 30), it was 58.5 cents per mile.

How rate calculations are done

The 3-cent increase from the 2022 midyear rate is somewhat surprising because gas prices are currently lower than they have been. On December 29, 2022, the national average price of a gallon of regular gas was $3.15, compared with $3.52 a month earlier and $3.28 a year earlier, according to AAA Gas Prices. However, the standard mileage rate is calculated based on all the costs involved in driving a vehicle — not just the price of gas.

The business cents-per-mile rate is adjusted annually. It’s based on an annual study commissioned by the IRS about the fixed and variable costs of operating a vehicle, including gas, maintenance, repair, and depreciation. Occasionally, if there’s a substantial change in average gas prices, the IRS will change the cents-per-mile rate midyear, as it did in 2022.

Standard rate versus actual expenses

Businesses can generally deduct the actual expenses attributable to business use of vehicles. This includes gas, oil, tires, insurance, repairs, licenses, and vehicle registration fees. In addition, you can claim a depreciation allowance for the vehicle. However, in many cases, certain limits apply to depreciation write-offs on vehicles that don’t apply to other types of business assets.

The cents-per-mile rate is beneficial if you don’t want to keep track of actual vehicle-related expenses. With this method, you don’t have to account for all your actual expenses. However, you still must record certain information, such as the mileage for each business trip, the date, and the destination.

Using the cents-per-mile rate is also popular with businesses that reimburse employees for business use of their personal vehicles. These reimbursements can help attract and retain employees who drive their personal vehicles a great deal for business purposes. Why? Under current law, employees can’t deduct unreimbursed employee business expenses, such as business mileage, on their own income tax returns.

If you do use the cents-per-mile rate, keep in mind that you must comply with various rules. If you don’t comply, the reimbursements could be considered taxable wages to the employees.

The standard rate can’t always be applied

There are some cases when you can’t use the cents-per-mile rate. It partly depends on how you’ve claimed deductions for the same vehicle in the past. In other situations, it depends on if the vehicle is new to your business this year or whether you want to take advantage of certain first-year depreciation tax breaks on it.

As you can see, there are many factors to consider in deciding whether to use the standard mileage rate to deduct vehicle expenses. We can help if you have questions about tracking and claiming such expenses in 2023 — or claiming 2022 expenses on your 2022 income tax return.
