The IRS sets mileage rates for employees who operate their own personal vehicles at work (they also set rates for charitable, medical, and moving purposes).
What sometimes confuses people about this is that the IRS sets a mileage rate, but does not mandate reimbursement by the employer. Many employers think they have to reimburse mileage but, in reality, they don’t.
The IRS rate is a guideline for employers and a tax deduction opportunity for employees.
