Updated October 22, 2026. Quick answer: The SURS Tier I guide says a retiree who returns to work for a SURS-covered employer must notify SURS, cannot be re-employed until retired at least 60 calendar days, and faces a reduction or suspension of the annuity if post-retirement earnings exceed the limits. The statute adds that a return to work within the first 60 days of the payment period cancels the annuity and requires a refund of the payments received. For an annuity that began at age 60 or later, the limit is the highest pre-retirement academic year earnings minus the annual base annuity.
What this covers
The Tier I guide has a section headed “EMPLOYMENT AFTER RETIREMENT”. This page quotes that section. For the wider choices, see Illinois SURS retirement decisions and public pension retirement decisions.
What the guide says, situation by situation
Each row is the guide’s own wording.
| Situation | What the guide says |
|---|---|
| Telling SURS and the employer | “If you return to work with a SURS-covered employer, you must notify SURS of this employment, and you must also inform the SURS-covered employer that you are a SURS annuitant.” |
| Waiting period | “You may not be re-employed by an employer covered by SURS until you have been retired for at least 60 calendar days.” The statute attaches a consequence to a return inside the first 60 days. Section 15-139(a) says “If an annuitant returns to employment for an employer within 60 days after the beginning of the retirement annuity payment period, the retirement annuity shall be cancelled, and the annuitant shall refund to the System the total amount of the retirement annuity payments which he or she received.” It adds “If the retirement annuity is cancelled, the participant shall continue to participate in the System.” |
| If you exceed the limits | “If you exceed the limits, your benefit is subject to reduction or suspension.” Section 15-139(b) reduces one part of the annuity. For an annuitant who retires before age 60 and is paid, in any month, more than the monthly retirement annuity for work after retirement for an employer under the System, “that portion of the monthly retirement annuity provided by employer contributions shall not be payable”; for one who retires at 60 or over and is paid, in an academic year, more than the difference between his or her highest annual earnings before retirement and the annual retirement annuity, that portion “shall be reduced by an amount equal to the compensation that exceeds such difference”. |
| Annuity began at age 60 or later | “your earnings from a SURS-covered employer during any academic year after you retire, combined with your annual base annuity from SURS, may not exceed your highest earnings during any academic year before you retired.” |
| Annuity began before age 60 | “your base monthly earnings from an employer covered by SURS may not exceed your current monthly base annuity.” |
How the limit works once set
“Once the annual earnings limitation is calculated, it does not change.” For an annuity that began before age 60 the guide adds: “The earnings limitation is increased each year by the Automatic Annual Increase (AAI).” On when the limit arrives, “Earnings limitation information will be forwarded to you upon finalization of your retirement claim.”
The guide’s own example, recomputed
The guide’s example reads: “If your highest academic year earnings during your career were $50,000 and your annual base annuity is $24,000”. It then states the annual earnings limitation. Recomputed here: the base annuity of $24,000 is $2,000 a month times 12 months, and $50,000 minus $24,000 is $26,000 and that is the limitation the guide prints.
The annual increase that feeds the limit
“Each Jan. 1, your monthly retirement benefit will automatically receive a 3% compounded increase.” “The first AAI will begin on the Jan. 1 following the month in which you retire and will be prorated for the number of months you were retired.”
Going back to active membership
“If you become reemployed with a SURS-covered agency and are considering resuming active participation in SURS, thus foregoing your annuity payments, contact SURS to discuss the special limitations that may apply.” Section 15-139(c) sets a condition for resuming active status: “If an employer certifies that an annuitant has been reemployed on a permanent and continuous basis or in a position in which the annuitant is expected to serve for at least 9 months, the annuitant shall resume his or her status as a participating employee” on filing an election to forgo all annuity payments. If the employment ends before 9 months for a reason other than death, the section says “The normal and survivors insurance contributions which are deducted during this period shall be refunded to the annuitant without interest” and the status does not change. Illinois tax treatment of SURS payments is on how Illinois taxes retirement income.
What the guide does not say
The section prints the limits but not the definition of “base annuity” beyond the example, does not list which employers are SURS-covered, and says nothing about the rules for Tier II members. Ask SURS for your own earnings limitation before accepting a job. One rule falls on the employer, not the retiree. Section 15-139.5(e) says “The employer contribution required under this Section for employment of an affected annuitant in an academic year shall be equal to 12 times the amount of the gross monthly retirement annuity payable to the annuitant for the month in which the first paid day of that employment in that academic year occurs, after any reduction in that annuity that may be imposed under subsection (b) of Section 15-139”. An annuitant becomes an affected annuitant on the first day of the academic year after the one in which, while receiving the annuity, he or she earns from employers under the System compensation “in excess of 40% of his or her highest annual earnings prior to retirement” (pay from grants that name a principal investigator does not count) and receives an annualized annuity of at least $10,000 (section 15-139.5(b)(2) and (3)).
Edition
This page reads the State Universities Retirement System of Illinois (SURS), Traditional Member Guide, Tier I, the file SURS served on 2026-10-22. It is the Tier I guide. SURS publishes a separate Tier II guide for Tier II members, which this page does not read, and the Illinois Pension Code and your own SURS account control over this summary.
Common mistakes
- Starting work before 60 calendar days have passed. The guide says “You may not be re-employed by an employer covered by SURS until you have been retired for at least 60 calendar days.”
- Not telling SURS. The guide says “you must notify SURS of this employment” and tell the employer you are an annuitant.
- Expecting the limit to be recalculated. The guide says “it does not change.” for an annuity that began at 60 or later.
