The Internal Revenue Service issued Revenue Procedure 2013-22 yesterday (March 28, 2013). The Revenue Procedure describes the Service’s new procedure for issuing opinion letters and advisory letters for prototype and volume-submitter § 403(b) plans; it revises the proposed procedure that was released four years ago in Announcement 2009-34. As part of the proposed procedure, the Service indicated that it intended to offer a similar procedure for individually-designed § 403(b) plans. Since then, the Service has changed course and determined that it is not feasible for it to offer determination letters for individually-designed § 403(b) plans at this time, given the Service’s limited resources. Although prototype and volume submitter plans can be convenient for employers to adopt initially, as Julie Edmond explained in the March 29th edition of Tax Notes Today, such plans “often lack the flexibility to accommodate the changing demographics of the workforce or unexpected changes in the organization and can quickly reach a point where they do not really work for the employer.” Accordingly, even though the Service does not plan to issue determination letters for individually-designed plans any time soon, plan sponsors of § 403(b) plans may be better served over the long run by using individually-designed plans — which allow plan sponsors to consider the specific needs of their employees and their organization, and to adapt as staffing and economic factors change. Revenue Procedure 2013-22 is scheduled for publication on April 29, 2013 in Internal Revenue Bulletin 2013-18.
