Elective Deferral Sources

?
Multiple Deferral Sources
The 402(g) limit applies to ALL elective deferrals across all employers/plans in a calendar year.
If a participant works for multiple employers, you must aggregate all deferrals to determine if there's an excess.
This is the most common cause of 402(g) excess deferrals.
Source #1 (Primary Employer)
?
Employer Identification Number
The 9-digit EIN identifies the employer. Format: XX-XXXXXXX
Helps track which plan/employer the deferrals came from.
?
Pre-Tax Elective Deferrals
Traditional 401(k) salary deferrals made on a pre-tax basis.
  • Reported in W-2 Box 12 with Code D
  • Count toward the 402(g) limit
?
Designated Roth Deferrals
After-tax Roth 401(k) deferrals (already taxed).
  • Reported in W-2 Box 12 with Code AA
  • Count toward the 402(g) limit
If excess is Roth, only earnings are taxable at distribution.
?
Catch-Up Contributions (Section 414(v))
Additional deferrals for participants age 50+ (or 60-63 for super catch-up).
Important: These are NOT subject to the 402(g) limit and are excluded from excess calculations.
?
Allocable Earnings
Earnings attributable to the excess deferral through December 31 of the deferral year.
  • Recordkeeper typically calculates this
  • Distributed with the excess
  • Taxable in year distributed

Note: Include all elective deferrals across all employers. Catch-up contributions (Section 414(v)) are excluded from the 402(g) limit.
