Pension RC, if this participant’s question is whether a distribution (if not rolled over) is or isn’t subject to an additional income tax on a too-early distribution, sorting out what “the date on which the [participant] attains age 59½” means might involve a series of questions:
Considering the payer or other service provider that does the Form 1099-R, what measurement rule would it (perhaps by using software) apply, likely using the plan’s records of the distributee’s birthdate and the distribution’s date, to discern whether the distributee had or had not attained age 59½ on the distribution’s date?
If a Form 1099-R would code the distribution as an early distribution, is the distributee ready to file his tax return based on a position inconsistent with the Form 1099-R?
If the IRS detects a mismatch and asks for the taxpayer’s explanation, how confident would he be in defending his tax-return position?
