IRS Form 2678
IRS Form 2678 is the only way that a person can be designated as an “employer” agent authorized to withhold taxes. If this form has not been submitted to the IRS, you are not an “employee” and all federal taxes taken from your pay are illegally withheld, even if you begged to have them deducted.

(19) Payor. The term payor is defined in § 31.3406(a)-2 of this chapter and § 1.6049-4(a)(2) and generally includes a withholding agent, as defined in § 1.1441-7(a). The term also includes any person that makes a payment to an intermediary, flow-through entity, or U.S. branch that is not treated as a U.S. person to the extent the intermediary, flow-through, or U.S. branch provides a Form W-9 or other appropriate information relating to a payee so that the payment can be reported under chapter 61 of the Internal Revenue Code and, if required, subject to backup withholding under section 3406. This latter rule does not preclude the intermediary, flow-through entity, or U.S. branch from also being a payor.
