Did you know tax-deductible mileage rates change from year to year?

It may seem like common sense that deductible mileage rates would change from year to year.

But it's also one of those things that's easy to forget. After all, the tax world can be a complicated space; and keeping up with the "devil in the detail" is one of the reasons it helps to have an accountant in your corner.

Why do rates change from year to year?

In a nut shell, rates change over time because the cost of operating a vehicle changes over time. As the IRS states, "The standard mileage rate for business is based on an annual study of the fixed and variable costs of operating an automobile, including depreciation, insurance, repairs, tires, maintenance, gas and oil. The rate for medical and moving purposes is based on the variable costs, such as gas and oil. The charitable rate is set by law."
