shouldn't there be something on my paycheck showing amount reimbursed or at the very least======>>As said , it depends; How your ER report your reimbursed mileage expenses depends on the accounting method he uses for these types of expenses. Under a non-accountable plan, the mileage expenses you accrue do not have to be justified or substantiated with receipts or invoices. If the reimbursement is given as an advance, you may keep unspent money under a non-accountable plan as opposed to having to return money that wasn't needed or was spent on non-business expenses. Your ER is also under a non-accountable plan if he reimburses or advances your funds that he expects may not be used to pay for business expenses or he pays an amount that he otherwise would have paid as your wage onW2.on the contrary, If he is using an accountable plan, none of your mileage expenses can be reported as income on your w2, so he/you have no reporting requirements. So, if he is under a non-accountable plan, you must report the mileage reimbursement as earnings on your W-2 Form as wages in Box 1 of yourW-2 Form. The reimbursement amount is subject to federal income, fica tax.
wouldn't I have to be submitting the total mileage to him on some form (which I do not do) if he was indeed reimbursing me?======>>> under accountable plan, the plan must require you to provide information that is sufficient to enable the employer to identify the specific nature of each expense and to conclude that the expense is attributable to business activities. Thus, each element of an expenditure or use must be substantiated. It is not sufficient for you, as an employee, merely to aggregate expenses into broad categories, such as travel, or report individual expenses through the use of vague, non-descriptive terms, such as miscellaneous business expenses. The IRS has ruled that an expense reimbursement arrangement that allows you to use electronic receipts and expense reports can qualify as an accountable plan if the electronic receipts and expense reports provide sufficient information to substantiate claimed expenses; an accountable plan is a plan that requires you to substantiate expenses, any amounts in excess of substantiated expenses to be returned to your employer..he is considered to have accounted to you, if your mileage expenses do not exceed the rate established by the federal government ;if your expenses do exceed that rate, the amount in excess must be reported as wages and added in Box 1 ofyour W-2 form. In this case, any substantiated reimbursements are reported in Box 12 using Code L on your W-2 Form. The excess amount is subject to federal income, fica taxes. Under a non-accountable plan, the mileage expenses you accrue do not have to be justified or substantiated with receipts or invoices..
