Except as provided in subdivision 3 for after-tax contributions, a distributee may elect, at the time and in the manner prescribed by the plan administrator, to have all or any portion of an eligible rollover distribution paid directly to an eligible retirement plan as specified by the distributee.
For distributions of after-tax contributions which are not includable in gross income, the after-tax portion may be transferred only to an individual retirement account or annuity described in section 408(a) or (b) of the Internal Revenue Code, to a Roth individual retirement account described in section 408A of the Internal Revenue Code, to a qualified plan described in either section 401(a) of the Internal Revenue Code, or to an annuity contract described in section 403(b) of the Internal Revenue Code, that agrees to separately account for the amounts transferred, including separately accounting for the portion of the distribution which is includable in gross income and the portion of the distribution which is not includable.
