includible compensation
(3) Includible compensation For purposes of this subsection, the term “includible compensation” means, in the case of any employee, the amount of compensation which is received from the employer described in paragraph (1)(A), and which is includible in gross income (computed without regard to section 911) for the most recent period (ending not later than the close of the taxable year) which under paragraph (4) may be counted as one year of service, and which precedes the taxable year by no more than five years. Such term does not include any amount contributed by the employer for any annuity contract to which this subsection applies. Such term includes— (A) any elective deferral (as defined in section 402(g)(3) ), and (B) any amount which is contributed or deferred by the employer at the election of the employee and which is not includible in the gross income of the employee by reason of section 125, 132(f)(4), or 457.
