Can owners (or other participants) make 401(k) deferrals after they attain age 70.5? Is this a plan document issue; does the document need to allow for this?
Yes, and no. A plan document does not have to explicitly state that a participant over 70 1/2 can defer; a 401(k) plan is not permitted to impose a maximum age on the right to defer. With regard to owners, the same rule applies, although minimum distributions will also be required after age 70 1/2. These are two separate and independent rules; one does not affect the other.
