Choice "C" is correct. Under a nonaccountable plan, $4,800 ($400 per month x 12 months) must be reported as part of Mel's gross income for the year (in fact, the $4,800 will be included as part of Mel's taxable wages on Mel's W-2).Rule: Under a nonaccountable plan (i.e., expenses are not reported to the employer), any amounts received by an employee from the employer must be reported by the employer as part of wages on the employee's W-2 for the year (and subject to income tax withholding requirements). The gross amount received is reported as income.Rule: Any expenses taken against the gross amount received in a nonaccountable plan (e.g., the car mileage expenses and the reimbursement to the company) are considered miscellaneous itemized deductions and are subject to the 2% AGI limitation.Note: The examiners have attempted to trick the candidate into thinking that this is in some way an accountable plan because they provided for a return of excess funds received to the employer. However, remember that the question specifically states that the plan is nonaccountable.Choices "d", "a", and "b" are incorrect, per the above rules.
