It depends. Check your employer's plan year and inquire with the plan administrator as to when the last day would be for additional contributions for 2024.

  • The deadline for employer contributions to a 403(b) plan for the 2024 calendar year depends on the employer's fiscal year and the plan's type. 
  • For a 403(b) plan that is a money-purchase plan (a relatively rare occurrence), there is a minimum funding deadline of 8.5 months following the close of the plan year (September 15 for calendar year plans). After 8.5 months, the contribution can still be made, but it is subject to a 10% excise tax.
