On January 29, 2016, the IRS issued Notice 2016-16 that provides guidance on mid-year changes to a safe harbor plan under sections 401(k) and 401(m) of the Internal Revenue Code. The guidance provides that a mid-year change either to a safe harbor plan or to a plan’s safe harbor notice does not violate the safe harbor rules, provided that applicable notice and election opportunity conditions are satisfied and the mid-year change is not a prohibited mid-year change, as described in the IRS Notice.

The IRS Notice doesn’t require any additional notice or election conditions for changes to information that is not required safe harbor notice content, even if that information is provided in a plan’s safe harbor notice. For purposes of the guidance, a mid-year change is a change that is first effective during the plan year, but not effective as of the beginning of the plan year, or a change that is effective as of the beginning of the plan year, but adopted after the beginning of the plan year.
