Kentucky Form 4972-K is a tax form used by individuals to calculate the state tax on lump-sum distributions received from qualified retirement plans. This form applies specifically to individuals born before January 2, 1936, who qualify to file federal Form 4972. Lump-sum distributions are typically payouts from retirement plans, pensions, or other qualified accounts. The form allows individuals to calculate how much of the lump-sum distribution is taxable, taking into account exclusions and reductions allowed by Kentucky law.
