(a) Introduction. Under section 4961 (b) and (c), the period of limitations on collection may be suspended and assessment or collection of first or second tier tax may be prohibited during the pendency of administrative and judicial proceedings conducted to determine a taxpayer's liability for second tier tax. This section provides rules relating to the suspension of the limitations period and the prohibitions on assessment and collection. In addition, this section describes the administrative and judicial proceedings to which these rules apply.

A proceeding is described in this subparagraph (3) if it is a proceeding commenced under section 7422, in accordance with the provisions of § 53.4963-1(e) (4) and (5) (relating to prerequisites to extension of the correction period during certain refund proceedings), and with respect to the taxpayer's liability for second tier tax.
