As anticipated by plan sponsors of closed defined benefit pension plans, the IRS issued Notice 2018-69, the fourth extension for an additional year of the temporary nondiscrimination relief for “closed” defined benefit pension plans originally announced by the IRS during 2014. The extended relief applies to plan years beginning before 2020 for those “closed” plans that satisfy certain conditions in Notice 2014-5. The relief for “closed” defined benefit plans refers to those defined benefit plans amended prior to December 13, 2013, to limit ongoing accruals to some or all employed participants in the plan as of a particular date, thus no longer admitting new participants into the plan.
