For one who is not renounced, the threefold fruits of action – desirable, undesirable and mixed – accrue after death. But those who are in the renounced order of life have no such result to suffer or enjoy.

A person in Kṛṣṇa consciousness acting in knowledge of his relationship with Kṛṣṇa is always liberated. Therefore he does not have to enjoy or suffer the results of his acts after death.
