Counties are responsible for making the proper FICA and FIT withholdings.  The county makes quarterly payments and reports to the Internal Revenue Service and the Social Security Administration. Counties must be aware of the taxation of fringe benefits, particularly the use of county-owned vehicles, as being income to the employees.  If the county fails to make the proper withholdings from income, serious penalties can be imposed by the Internal Revenue Service.  County officials may be responsible for filing Form 1099s with the IRS to report these benefits.
