Expansion of Employee Plans Compliance Resolution System (a) In general Except as otherwise provided in regulations prescribed by the Secretary of the Treasury or the Secretary's delegate (referred to in this section as the Secretary ), any inadvertent failure to comply with the rules applicable under section 401(a), 403(a), 403(b), 408(p), or 408(k) of the Internal Revenue Code of 1986 may be self-corrected under the Employee Plans Compliance Resolution System (as described in Revenue Procedure 2018–52 or any successor guidance), except to the extent that such failure was identified by the Secretary prior to any actions which demonstrate a commitment to implement a self-correction.
