(a) Exempt status. -- A trust forming part of a stock bonus, pension, or profit-sharing plan of an employer for the exclusive benefit of his employees or their beneficiaries shall not be taxable under this chapter and, except as expressly provided in this section, no other provision of this chapter shall apply with respect to such trust or to its beneficiary if such trust meets the requirements for exemption from federal income tax under sections 401, 402, and 501(a) of the Internal Revenue Code of 1986; provided, that to the extent that the trusts have unrelated business income subject to tax under section 511 of the Internal Revenue Code of 1986, the unrelated business income shall be taxed in the same manner and to the same extent as the tax imposed by subchapter VII of this chapter, except as hereinafter in this section expressly provided.

(b) Distributions. -- The amount actually distributed or made available to any distributee by any such trust shall be taxable to him, in the year in which so distributed or made available, under § 47-1803.02(b)(2) as if it were an annuity the consideration for which is the amount contributed by the employee.

(c) Nonexempt contributions. -- Contribution to a trust made by an employer during a taxable year of the employer which ends within or with a taxable year of the trust for which the trust is not exempt under subsection (a) of this section shall be included in the gross income of an employee for the taxable year in which the contribution is made to the trust in the case of an employee whose beneficial interest in such contribution is nonforfeitable at the time the contribution is made.
