The IRS released updated optional standard mileage rates that are used to calculate the deductible costs of using a car for business, charitable, medical or moving purposes. In 2022, the optional standard mileage rate for using a car for business purposes will be 58.5 cents per mile driven for business purposes (the 2021 rate was 56 cents per mile). The rate for miles driven for moving or medical purposes in 2022 will be 18 cents per mile (up from 16 cents in 2021).The charitable rate remains unchanged at 14 cents per mile. However, the suspension of all miscellaneous itemized deductions and the deduction for moving expenses for the 2018025 tax years means that most taxpayers who previously deducted these expenses will no longer be entitled to do so. Those individuals who were previously entitled to take the business mileage expense deduction as an above-the-line deduction, however, many continue to do so.
