The panel will display the following fields:
Annual Limit on 403(b) Contributions
This is your total limit for 403(b) contributions. These include your voluntary contribution to the Basic Retirement Plan, and any 403(b) SRA contributions. The U-M match is a 401(a) contribution, which does not count against your 403(b) limit.
Base Salary
This is your base rate of pay; it does not include shift and administrative differential, overtime, shift bonus, incentive pay under the Medical Service Plan, longevity pay, or summer salary for instructional staff. Your contribution and the U-M contribution (if you are eligible) will be provided on all eligible compensation in each paycheck, up to federal limits once you are enrolled.
Basic Retirement Plan
This section projects your contribution and the U-M contribution (if you are eligible) using your current base salary.
Compulsory or Voluntary
You may voluntarily enroll in the Basic Retirement Plan at any time. Participation becomes compulsory upon reaching all three criteria: age 35, 100% full time appointment, and two years of service in an eligible faculty or staff position. The calculation illustrates which plan you are enrolled in and which amounts count against the limit.
How Your Limit is Calculated
Your annual limit on 403(b) contributions is calculated according to Internal Revenue Code (IRC) guidelines. By subtracting your contribution to the Basic Retirement Plan, what remains is the amount you can make in 403(b) SRA contributions.
General 403(b) Limit
For 2025, your limit is automatically $23,500. If your salary is less than $23,500 for 2025, your limit is your salary. However, you must still pay the FICA taxes (Social Security and Medicare), contributions for other benefit plans, and deductions such as parking and United Way.
Age 50 or Older Catch-Up
For 2025, your limit is increased by $7,500 if you are age 50 or older by Dec. 31, 2025, making it $31,000 instead of $23,500.
Age 60-63 Catch-Up
Starting in 2025, your limit is increased by $11,250 if you are age 60, 61, 62, or 63 by Dec. 31, 2025. This makes the limit $34,750 instead of $23,500 under the new catch-up. The limit returns to the $7,500 catch-up amount ($31,000 total limit) at age 64.
15 Years of Service Catch-Up
The University of Michigan is no longer offering the 15 years of service catch-up.
Sample 403(b) Limit Calculation (2024 Limits)
Your salary = $50,000
Your 403(b) limit = $23,500
Your Basic Retirement Plan employee contribution = $50,000 x 5% = $2,500
Amount extra you could contribute to a 403(b) SRA = $23,500 - $2,500 = $21,000
SRA limit per pay period (monthly) = $21,000/12 = $1,750
Note: This example assumes you are eligible for the 5% employee contribution with 10% U-M contribution and you are younger than age 50.
