To return to youngbenefitslawyer’s question, before 2025 is not the relevant time for whether a “new” § 401(k) arrangement was “established”.
The exception Internal Revenue Code of 1986 § 414A(c)(2)(A)(i) provides is for a § 401(k) arrangement “established” by December 28, 2022.
An arrangement established after that date need not provide an automatic-contribution arrangement for 2023 or 2024, but must for 2025 meet Internal Revenue Code of 1986 § 414A(a)’s condition.
That’s so if a § 401(k) arrangement became established, for example, on December 30, 2022—a closing date used for many 2022 transactions.
If this afternoon one is an employee-benefits lawyer advising on a merger, acquisition, or other deal scheduled to close in seven business days on January 31, one must render her advice as best she can without waiting for Treasury’s or its Internal Revenue Service’s interpretation.
Some lawyers rendered that advice in December 2022.
