Generally, an employer will have an accountable plan if it pays business expenses that would otherwise be deductible by the employee, requires the employee to substantiate the expense, and does not permit the employee to keep any reimbursements that exceed expenses. If the employer does not use an accountable plan, mileage reimbursement would be included in your wages on Form W-2. You may usually deduct either your actual business automobile expenses or use the standard mileage rate. You may use either the standard mileage rate or the actual cost method in calculating your car or truck expenses. If you use the standard mileage rate, do not compute or deduct depreciation.
Depreciation is an expense that is used with the actual cost method.
