Maximum Allowable Contributions
The IRS elective contribution limit to a 403(b) for 2023 starts at $22500. If you are over the age of 50, your contribution limit increases to $30,000.
The Fifteen Year Cap Expansion Option, commonly referred to as service-based catch up, may also be available to veteran employees having 15 years or more with their current employer and whose total past 403(b) annual contributions average under $5,000 per year of employment. This allowance has a $3,000 maximum amount per year with a lifetime maximum of $15,000. A qualified employee could, for example, contribute an additional $1,000 per year for 15 years to reach the $15,000 lifetime maximum.
