IU Tax Deferred Account (TDA) Retirement Plan

The IU Tax Deferred Account (TDA) plan is a section 403(b) defined contribution retirement plan. This is a voluntary employee-funded plan; therefore, the participant makes all plan contributions.

The information on this page is only a summary. Review the IU Tax Deferred Account (TDA) Plan – Plan Document for a detailed description of the terms and conditions of the Plan.

Plan Details

  • Academic (including IU Residents) or Staff employee appointed at 50% or more full-time equivalent (FTE); or
  • Part-Time employee appointed as “Part-Time with Retirement”


All newly eligible employees are automatically enrolled in the plan at a 5% pre-tax contribution level, but have the option to waive or change their enrollment at any time. 

Existing eligible employees can enroll in the plan or change their contribution level at any time by following these step-by-step enrollment instructions. Instructions to setup your online Fidelity NetBenefits account, select your investments, and designate your beneficiaries are also available on this page.


Employees make all contributions to the plan. Contributions may be made on a pre-tax or after-tax Roth basis, and can be a flat-dollar amount or a percentage of pay. See the section below titled ‘Contribution Limits’ for additional details. 

Contribution Limits

  • Plus an additional $7,500 for 2023/2024 if you are age 50+

A participant is always 100% vested in their plan account.

Distributions & Withdrawals

You can withdraw TDA funds held at Fidelity while still employed by IU if you are age 59½ or older, or at any age after your IU employment ends.

  • Distributions of pre-tax contributions are subject to a 20% federal income tax withholding. 
  • Distributions of Roth (after-tax) contributions are tax-free if they are made (1) after a 5-year holding period (begins January 1 of the year you made your first Roth contribution); and (2) after you reach age 59½, become disabled, or pass away. 
  • Distributions made prior to reaching age 59½ are generally subject to a 10% early withdrawal penalty, even if you are no longer employed by the university.

A loan may be available from your IU TDA. You are limited to one loan across your IU supplemental retirement plan accounts (IU TDA and 457(b)) held at Fidelity.

Before you make the decision to take a loan from your account, consider the following:

  • Loans are subject to both federal tax code and investment company rules and regulations.
  • In most cases, you don’t pay taxes or penalties on a loan but you do repay the loan with after-tax dollars plus interest and there may be additional fees.

To request a loan, contact Fidelity at 800-343-0860 or log in to your Fidelity NetBenefits account and select ‘Loans or Withdrawals’ from the Quick Links menu next to the plan name.

Options When You Separate from IU

All plan contributions stop when your employment with IU ends. Upon termination of employment, you may:

  • Leave accumulations in the plan account and continue to manage investments;
  • Withdraw all or a portion of vested plan account accumulations (subject to income taxes and/or penalty taxes); or
  • Roll over all or a portion of vested plan account accumulations to an eligible retirement plan (e.g., an IRA).

After terminating employment with the university, most transactions related to your plan account are handled directly with the applicable investment company. For more information, review the Benefits After Separation Guide.

Required Minimum Distributions (RMD) at Age 72
Federal law requires participants to begin receiving at least a partial distribution of tax-deferred retirement account funds by April 1 of the calendar year following the year he/she reaches age 72, or upon retirement/separation, whichever is later. Failure to withdraw the RMD annually by the applicable deadline can result in substantial tax penalties.
