The IRS recently issued Notice 2018-95 to provide transition relief to 403(b) plans that erroneously excluded part-time employees from eligibility to make elective deferrals when the employees should have been eligible to participate under the “once-in-always-in” requirement (“OIAI”). Under the OIAI requirement, once an employee is eligible to make elective deferrals, the employee may not be excluded from eligibility for making elective deferrals in any later year on the basis that the employee is a part-time employee. The IRS issued Notice 2018-95 to provide transition relief because many employers that sponsored 403(b) plans did not realize that the OIAI requirement applied to the part-time exclusion.

Less than a week after issuing significant modifications to the Employee Plans Compliance Resolution System (EPCRS) (as described in our March 31, 2015 blog), the Internal Revenue Service (IRS) further modified EPCRS through the release of Revenue Procedure 2015-28.  The new guidance provides welcome relief (provided certain requirements are met) from the current standard (or safe harbor) EPCRS correction method for elective deferral failures, which has been widely viewed as providing affected participants with a windfall.  Also, in an effort to facilitate the adoption of automatic contribution arrangements and prompt correction of failures, the IRS has established favorable safe harbor correction methods for elective deferral failures.
