Special rules for simplified employee pensions

shall not be treated as distributed or made available to the employee or as contributions made by the employee,

if such contributions are made pursuant to an arrangement under section 408(k)(6) under which an employee may elect to have the employer make contributions to the simplified employee pension on behalf of the employee, shall not be treated as distributed or made available or as contributions made by the employee merely because the simplified employee pension includes provisions for such election, and

in the case of any contributions pursuant to a simplified employer pension which are made to an individual retirement plan designated as a Roth IRA, such contribution shall not be excludable from gross income.

Contributions made by an employer to a simplified employee pension with respect to an employee for any year shall be treated as distributed or made available to such employee and as contributions made by the employee to the extent such contributions exceed the lesser of—

(A) 25 percent of the compensation (within the meaning of section 414(s)) from such employer includible in the employee’s gross income for the year (determined without regard to the employer contributions to the simplified employee pension), or

(B) the limitation in effect under section 415(c)(1)(A), reduced in the case of any highly compensated employee (within the meaning of section 414(q)) by the amount taken into account with respect to such employee under section 408(k)(3)(D).

Any amount paid or distributed out of an individual retirement plan pursuant to a simplified employee pension shall be included in gross income by the payee or distributee, as the case may be, in accordance with the provisions of section 408(d) (or section 408A(d) in the case of an individual retirement plan designated as a Roth IRA).
