University of Illinois System

State Universities Retirement System (SURS)

This information is in the process of being updated to reflect changes in SURS eligibility for employment beginning on or after Jan 1, 2023.

SURS is the retirement administrator for employees in public higher education in the State of Illinois. Participation is mandatory if you are eligible. When you become eligible, you will make a one-time, irrevocable election among three available retirement benefit plans. Benefits in retirement depend on your assigned Tier and your plan election. See the SURS website for full details.

If you previously worked for the University or another SURS-covered employer, you will resume contributions to the SURS plan you chose when you first became an eligible participant; you will not have an opportunity to select a different plan.

For Employees New To SURS

If you are newly eligible for SURS, you have six months from your date of eligibility to make your plan election. After six months, you will default into the Traditional Plan. Your election, or default, is a lifetime, irrevocable and unchangeable decision. Be sure to:

  • Read the materials SURS mails to your home.
  • Attend a SURS Plan Choice Webinar.
  • See New to SURS for a step-by-step guide to choosing your plan, and answers to common questions from new participants.

The information packet SURS mails to you will also contain an enrollment form, which you can mail to SURS to make your plan selection. The packet will also contain instructions for making your selection online.


Participation in SURS is required if you are eligible. You are eligible if you work continuously for at least one academic term or four months, whichever is less, and your employment is not temporary, intermittent or irregular.

You are not eligible for SURS if any of the following apply to you:

  • You are a student who regularly attends classes at a college or university participating in SURS and you are employed on a temporary part-time basis.
  • You were employed under the Comprehensive Employment Training Act on or after July 1, 1979.
  • You hold a J-1 or F-1 visa and have not established residency.
  • You first became a SURS member (or other eligible Illinois reciprocal system) prior to 1/1/2011 and you are currently receiving a retirement annuity.
    • Important: If you first became a SURS member (or other eligible Illinois reciprocal system) on or after 1/1/2011 you are subject to a different provision. When receiving an annuity and you return to work, your annuity will be suspended and you will again contribute to SURS.

Two-Tiered SURS System

You participate in either SURS Tier I or Tier II depending on your first date of eligibility.

  • Employees who were certified as SURS-eligible prior to January 1, 2011, participate in Tier I.
  • Employees who were certified as SURS-eligble on or after that date, participate in Tier II.

You will find additional benefit information on page two (2) of SURS in Brief.


Police and firefighters may be eligible for special contribution rates, and should consult the appropriate SURS Member Guides.

Mandatory contributions to your SURS plan, 8% of pensionable earnings, are deducted from your paycheck on a pre-tax basis. How your contributions are allocated varies depending on which plan you elected. The State of Illinois Employer Contributions also vary based on your plan.

Please be aware that while eligible for SURS, you are not covered by Federal Social Security, and Social Security taxes are not withheld from your university earnings. Read the Statement Concerning Your Employment in a Job Not Covered by Social Security.

Employees hired on or after April 1, 1986, are subject to withholding of the Federal Medicare tax, which amounts to 1.45% of Medicare eligible salary.

To understand more about how SURS is funded, see SURS in Brief.

Plan Options & Summary

Please see the SURS website for detailed information on each SURS retirement plan option and additional information about participating in SURS. 

SURS offers two Defined Benefit plans, and one Defined Contribution plan. All SURS retirement plans are 401(a), non-ERISA plans.

A Defined Benefit Plan provides you with a specific, guaranteed amount when you retire. The amount you receive is based on a formula which takes into account your years of service and salary history. SURS offers two Defined Benefit plans:

  • The Traditional Plan allocates 6.50% of your pay to your retirement, 0.50% to an automatic annual increase, and 1.00% to a survivor benefit used in the event of your death.
  • The Portable Plan allocates 6.50% of your pay to your retirement, 0.50% to an automatic annual increase, and 1.00% to portability, allowing for a larger refund if you leave SURS before retirement.

The State of Illinois employer contribution is actuarially determined each year and averages about 9.1% of the total earnings of all SURS participants in the Traditional and Portable plans. It is used to fund your retirement benefit and your eligibility for disability benefits. The Illinois pension code (under 40 ILCS 5/15-155) requires the state to contribute an amount each year necessary for the System to become funded at 90 percent of assets to liabilities by the end of the state fiscal year 2045.

The state contribution does not go directly to your individual retirement account, but rather is paid to the System and kept in a pooled account used to fund retirement benefits.

A Defined Contribution Plan does not provide a guaranteed amount at retirement. Instead, your contributions will be placed into an investment account, and retirement income will be based on the account balance. You bear the full risk in a Defined Contribution plan, as you have control over your account and your investment choices.

  • Under the SURS Retirement Savings Plan, you contribute 8.0% of earnings, and the state contributes 7.6%—of which up to 1% is used to provide you with eligibility for disability benefits.

You have six months from your initial date of eligibility to choose one of the SURS plans. This election is irrevocable – it cannot ever be changed, even if you leave SURS-covered employment. If you leave employment with the University and you are employed in the future by a participating SURS employer, you will again participate in your original plan selection. If you fail to make your SURS plan election within the 6-month period, then you will default into the Traditional Plan, and be unable to change plans.
