(a) Applicability of section. This section provides the rules for determining the taxation of amounts received from an employer-established plan which provides for distributions that are taxable under
section 72 (or for distributions that are taxable under
section 402 (a)(2) or (e), or
section 403(a)(2), in the case of lump sum distributions) and which also provides for distributions that may be excludable from gross income under
section 104 or
105 as accident or health benefits. For example, this section will apply to a pension plan described in
section 401 and exempt under
section 501 which provides for the payment of pensions at retirement and the payment of an earlier pension in the event of permanent disability. This section will also apply to a profit-sharing plan described in
section 401 and exempt under
section 501 which provides for periodic distribution of the amount standing to the account of a participant during any period that the participant is absent from work due to a personal injury or sickness and for the distribution of any balance standing to the account of the participant upon his separation from service. For purposes of this section, the term “contributions of the employee” includes contributions by the employer which were includible in the employee's gross income. Paragraphs (d), (h), and (i) of this section apply for taxable years beginning on or after January 1, 2015.
