Carol has now focused our attention on situations in which an individual is employed by two employers during the same year and is eligible to participate in 403(B) plans of both employers. Whether or not the periods of employment with the two employers overlap is immaterial for the analysis of applicable IRC Sec. 415 limitations. For simplicity, I will assume that neither employer offers any other tax advantaged plans of any kind. Also, it is helpful to distinguish between the "dollar" and "compensation" components of the 415©(1) limits as follows, where GL = General Limitation, A = A Election, B = B Election, and C = C Election:
Standard 415 Dollar Limit (SDL) = $30,000 (applies to GL, A, and C)
Modified 415 Dollar Limit (MDL) = $15,000 (applies to b)
Standard 415 Compensation Limit (SCL) = 25% of 415 Compensation (applies to GL and C)
Modified 415 Compensation Limit (MCL) = 25% of 403(B) Compensation + $4,000 (applies to b)
Next, one must distinguish between "employer-specific limitations," which involve compensation and contributions associated with a single employer, and "combined-employer limitations," which involve aggregate compensation and aggregate contributions associated with both employers. For these purposes, the following abbreviations will be used:
ER1 = Employer 1
ER2 = Employer 2
CER = Combined Employers
C1 = ER1 Contribution
C2 = ER2 Contribution
CC = CER Contribution
Since Carol points out that the two plans must be combined for 415 purposes, it follows that the same "election (GL, A, B, or C)" must be made for C1 and C2. Now things get more interesting, and "analysis by election" is the most efficient approach.
General Limitation Election
415 Dollar Limitation: Compliance with the CER SDL implies compliance with both the ER1 SDL and the ER2 SDL, so it suffices to apply the CER SDL. Notice that this requires "sharing of contribution data" between ER1 and ER2. Also notice that nothing is lost by applying the ER1 SDL and the ER2 SDL, in addition to the CER SDL, even though such applications are superfluous (this is common practice in programming methodology).
415 Compensation Limitation: Compliance with the ER1 SCL and the ER2 SCL imply compliance with the CER SCL, so it suffices to apply the employer-specific SCLs. One might push the envelope by applying only the CER SCL, but doing so would allow C1 to exceed the ER1 SCL or C2 to exceed the ER2 SCL, would require "sharing of compensation and contribution data" between ER1 and ER2, and would be inadvisable in any event. It seems prudent to require compliance with employer-specific 415 limits, even if they are not technically required.
A Election
415 Dollar Limitation: See Paragraph 1 under General Limitation Election.
415 Compensation Limitation: The 415 Compensation Limitation is replaced by the "Modified 403(B) Exclusion Allowance Limitation (based on the 120-month time period ending on the date of separation)," which is not a subject for this discussion.
B Election
415 Dollar Limitation: Compliance with the CER MDL implies compliance with both the ER1 MDL and the ER2 MDL, so it suffices to apply the CER MDL. Again, this requires "sharing of contribution data" between ER1 and ER2. Yet again, nothing is lost by applying the ER1 MDL and the ER2 MDL, in addition to the CER MDL, even though such applications are superfluous.
415 Compensation Limitation: Unfortunately, compliance with the ER1 MCL and the ER2 MCL do not imply compliance with the CER MCL, so it does not suffice to apply the employer-specific MCLs. This is most easily seen by noting that there is a "doubling up" of the extra $4,000 if only employer-specific MCLs are applied. Hence, it is essential that the CER MCL be applied, which requires "sharing of compensation and contribution data" between ER1 and ER2, not only for the year in question, but for earlier years if the employee fails to be employed full time for the entire year in question at both employers. Again, it seems prudent to require compliance with employer-specific 415 limits, even if they are not required technically. In applying the CER MCL, presumably time periods representing the "last full year of service" for each employer should be determined independently and resulting compensation figures should be aggregated.
C Election
415 Dollar Limitation: See Paragraph 1 under General Limitation Election.
415 Compensation Limitation: See Paragraph 2 under General Limitation Election.
Summary:
1. The same "Election" (GL, A, B, or C) must apply to participation in both 403(B) plans.
2. A single corresponding "Combined-Employer 415 Dollar Limitation" must be applied to aggregate contributions to the two 403(B) plans.
3. With the exception of the A Election, a separate corresponding "Employer-Specific 415 Compensation Limitation" should be applied to contributions to each 403(B) plan.
4. With the exception of the A Election, an overall corresponding "Combined-Employer 415 Compensation Limitation" must be applied to aggregate contributions to the two 403(B) plans, using combined compensation from the two employers (for the last full year of service in the B Election setting).
