Special rule for sick pay paid pursuant to certain collective-bargaining agreements

In the case of any sick pay paid pursuant to a collective-bargaining agreement between employee representatives and one or more employers which contains a provision specifying that this paragraph is to apply to sick pay paid pursuant to such agreement and contains a provision for determining the amount to be deducted and withheld from each payment of such sick pay—

(A) the requirement of paragraph (1)(C) that a request for withholding be in effect shall not apply, and

(B) except as provided in subsection (n), the amounts to be deducted and withheld under this chapter shall be determined in accordance with such agreement.

The preceding sentence shall not apply with respect to sick pay paid pursuant to any agreement to any individual unless the social security number of such individual is furnished to the payor and the payor is furnished with such information as is necessary to determine whether the payment is pursuant to the agreement and to determine the amount to be deducted and withheld.
