Tax-Deferred Retirement Savings Plans

As a CSU employee, you have three voluntary retirement savings plans available to you, which allow you to invest pre-tax dollars. The three plans are listed below:

  1. The CSU 403(b) Supplemental Retirement Plan
  2. The Savings Plus 401(k) Supplemental Retirement Plan
  3. The Savings Plus 457(b) Supplemental Retirement Plan

Contribution Limits

The IRS contribution limits for 2025 that affect 401k, 457, and 403b retirement plans are as follows:

  • The limit is generally $23,500, although larger limits may apply if you are age 50 or older.
  • In addition, employees with 15 or more years of service with CSU may be eligible to contribute an additional $3,000 per year, for up to five years, or a lifetime limit of $15,000.
  • Individuals who are age 50 or older, or will turn age 50 by the end of the 2025 calendar year, are eligible to contribution up to an additional $7,500 per year.
  • NEW Age Based Catch-Up contribution limit for those ages 60-63 is $11,250.

Each participant only gets one limit for contributions to all 403(b) and 401(k) plans, so if you are also a participant in another 403(b) and/or 401(k) plan, your combined contributions to those plans and to the CSU 403(b) Supplemental Retirement Plan in 2025, you are generally limited to $23,500.

If you do participate in more than one 403(b) and/or 401(k) plan, you are responsible for tracking and reporting the amount of all of your contributions to the plans so that the total amount of all your contributions to all plans in which you participate do not exceed the limit.
