IU Supplemental Retirement Plans

Indiana University offers two voluntary supplemental retirement plans—the IU 457(b) and the IU Tax Deferred Account (TDA)—to help you build retirement savings for your future. You make all contributions to these plans and can enroll at any time.
Advantages of these plans include:

  • Options—enroll in one or both plans at any time and contribute up to the IRS limit in each.
  • Flexibility—make pre-tax or Roth after-tax contributions (or both).
  • Systematic retirement savings—contributions are made regularly through IU payroll.
