Exception for highly compensated participants and key employees

In the case of a highly compensated participant, subsection (a) shall not apply to any benefit attributable to a plan year for which the plan discriminates in favor of—

(A) highly compensated individuals as to eligibility to participate, or

(B) highly compensated participants as to contributions and benefits.

In the case of a key employee (within the meaning of section 416(i)(1)), subsection (a) shall not apply to any benefit attributable to a plan for which the qualified benefits provided to key employees exceed 25 percent of the aggregate of such benefits provided for all employees under the plan. For purposes of the preceding sentence, qualified benefits shall be determined without regard to the second sentence of subsection (f).

For purposes of determining the taxable year of inclusion, any benefit described in paragraph (1) or (2) shall be treated as received or accrued in the taxable year of the participant or key employee in which the plan year ends.
