Fringe Benefits

Generally, you must determine the value of noncash fringe benefits no later than January 31 of the next year. Before January 31, you may reasonably estimate the value of the fringe benefits for purposes of withholding and depositing on time. For employment tax and withholding purposes, you can treat fringe benefits (including personal use of employer-provided highway motor vehicles) as paid on a pay period, quarter, semiannual, annual, or other basis. You do not have to choose the same period for all employees. You can withhold more frequently for some employees than for others. You can add the value of fringe benefits to regular wages for a payroll period and figure income tax withholding on the total. Or you can withhold federal income tax on the value of fringe benefits at the flat 25% rate that applies to supplemental wages.
