495—8.3 (97B) IRC Section 415(n) compliance. Service purchases made under this chapter and other posttax contributions shall not exceed the defined contribution limit then in effect under Internal Revenue Code Section 415(c), per calendar year. In addition, the amounts contributed for service purchases under this chapter shall not exceed the amount required to purchase the service according to the current cost schedules. In implementing these and the other requirements of IRC Section 415(n), IPERS shall use the following procedures.
	 8.3(1) If the member’s total benefit at retirement passes the fully reduced IRC Section 415(b) dollar limit test, IPERS shall pay the total benefit.
	 8.3(2) If the member’s total benefit at retirement fails the fully reduced IRC Section 415(b) dollar limit test, and the member made one or more service purchases, IPERS shall perform the applicable IRC Section 415 tests, with adjustments for posttax service purchases and other posttax contributions, and pay excess amounts, if any, under a qualified benefits arrangement authorized under Iowa Code section 97B.49I.
	 8.3(3) IPERS shall not permit the purchase of nonqualified permissive service credit, as defined under IRC Section 415(n), unless such service is specifically authorized by the Iowa legislature. If so authorized, a member must have five years of existing service to make such a purchase, and the quarters of nonqualified service purchased cannot exceed 20.
	 8.3(4) The limitations of this rule shall not apply to buy-backs of prior refunds. In addition, the annual limit under this rule shall not apply to service purchases grandfathered under the provisions of the Iowa Code and Section 1526 of the Taxpayer Relief Act of 1997.
	 8.3(5) If IPERS adopts rules and procedures permitting service to be purchased on a pretax basis, the amounts contributed will not be combined with posttax service purchases and other posttax contributions in applying the foregoing procedures.
	 8.3(6) The provisions of this rule shall apply to all vested members who have an account balance and to retired members.
	 8.3(7) The IRC Section 415(c) limitations shall not apply to a service purchase that qualifies as a direct rollover for an eligible retirement plan or a direct transfer from a plan qualified under IRC Section 403(b) or 457. The IRC Section 415(c) limits also shall not apply to a service purchase under subrule 8.1(3).
	 8.3(8) IPERS reserves the right to apply the limitations of IRC Section 415(n) on a case-by-case basis to ensure that such limits are not exceeded.
