(i) If the total distributions payable with respect to any employee under a trust described in
section 401(a) which in the year of distribution is exempt under
section 501(a) are paid to, or includible in the gross income of, the distributee within one taxable year of the distributee on account of the employee's death or other separation from the service, or death after such separation from service, the amount of such distribution, to the extent it exceeds the net amount contributed by the employee, shall be considered a gain from the sale or exchange of a capital asset held for more than six months. The total distributions payable are includible in the gross income of the distributee within one taxable year if they are made available to such distributee and the distributee fails to make a timely election under
section 72(h) to receive an annuity in lieu of such total distributions. The “net amount contributed by the employee” is the amount actually contributed by the employee plus any amounts considered to be contributed by the employee under the rules of
section 72(f),
101(b), and subparagraph (3) of this paragraph, reduced by any amounts theretofore distributed to him which were excludable from gross income as a return of employee contributions. See, however,
paragraph (b) of this section for rules relating to the exclusion of amounts representing net unrealized appreciation in the value of securities of the employer corporation. In addition, all or part of the amount otherwise includible in gross income under this paragraph by a non-resident alien individual in respect of a distribution by the United States under a qualified pension plan may be excludable from gross income under
section 402(a)(4). For rules relating to such exclusion, see
paragraph (c) of this section. For additional rules relating to the treatment of total distributions described in this subdivision in the case of a nonresident alien individual, see
sections 871 and
1441 and the regulations thereunder.
