The Internal Revenue Service FOIA-released a Notice to state IRS and anticipated Treasury interpretations of Internal Revenue Code § 403(b)(12) and § 410(b), and of ERISA §§ 202-203.
Additional Guidance with Respect to Long-Term, Part-Time Employees, Including Guidance Regarding Application of Section 403(b)(12) to Long-Term, Part-Time Employees under Section 403(b) Plans, Notice 2024-73, 2024-41 or 2024-42 I.R.B. --- (to be published Oct. 7 or 15, 2024), available at https://www.irs.gov/pub/irs-drop/n-24-73.pdf.
For an ERISA-governed § 403(b) plan, these interpretation distinguish between a 20-hours exclusion and a student exclusion. The IRS suggests: “The student employee exclusion . . . is . . . based on a classification . . . , rather than on service.” Under that interpretation, ERISA § 202(c) does not command a plan to make an I.R.C. § 3121(b)(10) student eligible to elect deferrals.
The Notice remarks: “The Secretary of the Treasury has interpretive authority over sections 202 and 203 of ERISA pursuant to Reorganization Plan No. 4 of 1978[.]”
