QUESTION PRESENTED
               You requested a legal opinion regarding whether E~’s receipt of benefits from a defined
                  benefit plan provided by the State Universities Retirement System (SURS) of Illinois
                  triggers the application of the Government Pension Offset (GPO) to any spousal benefits
                  to which he may be entitled.
               
               SHORT ANSWER
               The annuity benefit that E~ receives from SURS is a government pension that triggers
                  the application of the GPO.
               
               FACTUAL BACKGROUND
               SURS is an administrator of retirement and other benefits for employees of Illinois
                  public higher education including state universities, community colleges, and state
                  agencies. See SURS, All About SURS 1 (2018) [hereinafter All About
                     SURS]:
               
               
               About
                        SURS (last visited Mar. 5, 2018). The letter E~ submitted from SURS indicates that he
                  began employment with a SURS employer in July 1984, and that he continued his employment
                  there until June 2005. (E~ reported that he worked for the University of Illinois
                  – Urbana-Champaign.) E~’s pension rights vested in March 1992. He began receiving
                  pension benefits in June 2006, and as of August 2017 he was receiving a pension payment
                  of $8,253.79 per month. SURS described E~’s pension payment as a “defined benefit
                  based on money purchase calculation.”
               
               According to SURS, the “money purchase calculation” is one method of calculating the
                  benefit paid under its Traditional pension plan.[9] See SURS, Traditional Plan Member Guide 15 (rev. 2018) [hereinafter Traditional
                     Plan] (see PDF link below), Retirement
                        FAQs, SURS (last visited Mar. 5, 2018).
               
               
               Employees are required to make contributions from their earnings, and an employer
                  contribution is also attributed to the employees’ plan. See Traditional Plan, supra, at 2. Upon retirement, employees begin receiving retirement annuity payments under
                  the plan. The amount of benefit paid is determined by applying four available formulas
                  (one of which is the money purchase calculation); whichever formula results in the
                  highest payment will be used to set the defined benefit retirement payment received
                  by the employee. See
                     id. at 15.
               
               The Traditional Plan publication describes the “money purchase calculation” as follows:
               
               Money Purchase Calculation*
               
               *This calculation is not available to participants who began SURS-covered employment
                     on or after July 1, 2005. 
               The Money Purchase Formula is based on your accumulated normal retirement contributions
                  and interest, an imputed employer (State of Illinois) contribution, and your age at
                  retirement.
               
               Traditional Plan, supra, at 18.
               
               Moreover, the All About SURS publication explains that:
               
               …SURS is the sole source of retirement income for its participants. The state/employer
                  does not contribute to Social Security on the employee’s behalf, and there is no coordinated
                  benefit for SURS-covered employment from Social Security upon retirement.
               
               In addition, retirees who may qualify for Social Security benefits from other, non-SURS
                  covered employment, may be affected by the Windfall Elimination Provision or the Government
                  Pension Offset, resulting in an offset of their Social Security benefit.
               
               All About SURS, supra, at 1. Thus, SURS participants are not eligible for Social Security coverage based
                  on their employment, and Social Security taxes are not withheld from their SURS earnings.

               LEGAL BACKGROUND
               Government employers that provide their employees with retirement benefits are not
                  required to participate in Social Security. 42 U.S.C. § 410(a)(5), (7). If a government
                  entity provides retirement benefits to its employees and does not participate in Social
                  Security, its employees are “noncovered”; they pay no Social Security taxes on their
                  earnings and are not entitled to Social Security benefits based on those earnings.
                  Id.
               
               Congress enacted the GPO in 1977, which provides for a reduction in Social Security
                  spousal and certain other benefits if a person in noncovered public employment receives
                  a monthly periodic benefit that is based upon such individual’s earnings while in
                  the service of the Federal Government or any State (or political subdivision thereof).
                  See 42 U.S.C. § 402(k)(5)(A); 20 C.F.R. § 404.408a(a)(2). The Supreme Court summarized
                  the motivation behind the GPO in Heckler v. Mathews:
               
               [A]s part of a general reform of the Social Security system, Congress repealed the
                  dependency requirement for widowers and husbands. It concluded, however, that elimination
                  of the dependency test, by increasing the number of individuals entitled to spousal
                  benefits, could create a serious fiscal problem for the Social Security trust fund.
                  This problem was particularly acute with respect to the large number of retired federal
                  and state employees who would now become eligible for spousal benefits. Unlike most
                  applicants, who must offset any dual Social Security benefits against each other,
                  42 U.S.C. § 402(k)(3)(A), retired civil servants could, at the time of the 1977 Amendments,
                  receive the full amount of both the spousal benefits and the government pensions to
                  which they were entitled. Congress estimated that payment of unreduced spousal benefits
                  to such individuals could cost the system an estimated $190 million in 1979.
               
               To avoid this fiscal drain, Congress included as part of the 1977 Amendments a “pension
                  offset” provision that generally requires the reduction of spousal benefits by the
                  amount of certain federal or state government pensions received by the Social Security
                  applicant.
               
               465 U.S. 728, 732 (1984) (citations and footnote omitted).
               Because an individual who was receiving a Social Security retirement benefit based
                  entirely on covered employment would have his spousal benefit calculation reduced based on his own Social
                  Security retirement benefit, Congress concluded that it was appropriate to ensure
                  that the individual receiving a government pension based on noncovered employment should also have his spousal benefit adjusted. See SSA, Pub. No. 05-10007,
                     Government Pension Offset (2017), Heckler, 465 U.S. at 750. As relevant here, the GPO decreases an individual’s spousal benefit
                  by two-thirds of his government pension. 42 U.S.C. § 402(k)(5)(A); 20 C.F.R. § 404.408a(a)(1)(iii),
                  (d)(1).
               
               
               While there are exceptions that preclude the application of the GPO in certain circumstances,
                  they are primarily related to military personnel and government employment that also
                  became subject to the payment of Social Security taxes. 20 C.F.R. § 404.408a(b).
               
               DISCUSSION
               Our review of this case shows that E~ is receiving a government pension based on noncovered
                  employment, which triggers the application of the GPO to any spousal benefits to which
                  he may be entitled. 20 C.F.R. § 404.408a(a)(2). Specifically, the defined benefit
                  monthly payment E~ receives from SURS is based on his employment with an Illinois
                  public university, which is considered a state government employer. Thus, his is a
                  government pension. 20 C.F.R. § 404.408a(a)(1)(i). In addition, as noted above, SURS
                  employers do not participate in Social Security. As such, SURS participants are not
                  eligible for Social Security coverage based on their employment, and Social Security
                  taxes are not withheld from their SURS earnings. Thus, E~’s defined benefit payment
                  is related to noncovered employment for which he did not pay Social Security taxes.
                  20 C.F.R. § 404.408a(a)(1)(ii). None of the exceptions to the application of the GPO
                  apply here. 20 C.F.R. § 404.408a(b).
               
               In his Dec. 1, 2017 letter, E~ asserts that the GPO should not apply for two reasons.
                  First, he asserts that his pension payment is not based on earnings because the amount
                  of the pension payment is not calculated based on his earnings. He relies on SSA Publication
                  No. 05-10007, which states “we won’t reduce your Social Security benefits as a spouse,
                  widow, or widower if you: Receive a government pension that’s not based on your earnings.”
                  SSA, supra, at 2. His assertion is incorrect. As discussed above, the “money purchase calculation”
                  used to determine the amount of E’s pension payment is based on his and his employer’s
                  retirement contributions. And his contributions were a percentage of his earnings.
                  See Traditional Plan, supra, at 2 (“Your contributions are equal to 8% of your gross earnings….”). As such, they
                  are directly related to his earnings.
               
               Second, E~, relying on POMS GN 02608.400A.2a, asserts that the GPO does not apply because his pension is not his employer’s primary
                  retirement plan nor is it a supplemental plan. This assertion is also incorrect. First,
                  the POMS refers to the employee’s primary retirement plan, not the employer’s. POMS GN 02608.400A.2)a. So, whether his employer offered a different “primary” plan, as E~ asserts, is
                  not relevant. Under the POMS, if the pension E~ receives from SURS is his primary retirement plan, and it is based on earnings from noncovered government employment
                  (which it is, as discussed above), the GPO applies. Id. Further, even if this pension were not E~’s primary retirement plan, and instead
                  were a supplemental plan (which is somewhat unlikely given that it pays over $8,000
                  per month), it would nonetheless trigger the application of the GPO because both E~
                  and his employer made contributions on E~’s behalf. Id. (“If the plan is a supplemental plan, the payments are subject to GPO when the plan
                  payments contain employer or both employer and employee contributions.”).
               
               CONCLUSION
               For the reasons discussed above, we conclude that the pension E~ receives from SURS
                  is a government pension based on noncovered employment and, therefore, triggers the
                  application of the GPO to any spousal benefits to which he may be entitled.
