The IRS may change these limits from year to year. Limits are specified on this webpage for the 457(b), 403(b), and 401(a) Supplemental Retirement Plan.
457(b) IRS limits for 2024
Employee contributions
If you are under age 50, the maximum you (the employee) may contribute is ...
$23,000 - This is a cumulative limit. In other words, you may contribute up to $23,000 annually to all of your 457(b) accounts that you have with any and all employers. Consult a tax advisor for assistance.
If you are age 50 or older, the maximum you (the employee) may contribute is ...
$30,500 - Individuals age 50 or older may contribute up to the normal $23,000 limit plus a $7,500 “catch-up contribution.” This is a cumulative limit. In other words, you may contribute up to $30,500 to all of your 457(b) accounts that you have with any and all employers. Consult a tax advisor for assistance.
403(b) Pretax and 403(b) Roth After-Tax IRS limits for 2024
The same limits apply to the 403(b) Pretax and the 403(b) After-Tax as those listed above for the 457(b).
403(b) Pretax Irrevocable limits for 2024
Employees may contribute up to $69,000 annually. However, please remember that any contribution you choose toward the 403(b) Pretax Irrevocable is indeed an irrevocable election for the duration of your employment with the University. The irrevocable election must be made prior to your first period of employment. Your election will be in effect for the lifetime of the plan as long as you are employed with the University; if you come back to work for the UM System and the UM System has closed the plan, you will no longer make contributions to it.
The employee limit is the same, no matter your age. In rare circumstances, there may be an opportunity for catch-up contributions, depending on your age and voluntary 403(b) contributions.

Employee contributions
The same limits on employee contributions apply to the 401(a) SRP as what is listed above for the 403(a) Pretax Irrevocable. The 401(a) SRP is also irrevocable, as explained under the 403(a) Pretax Irrevocable.
