Publication 571
taxmap/pubs/p571-009.htm#en_us_201212_publink1000239631Generally, contributions to your 403(b) account are limited to the lesser of:
- The limit on annual additions, or
- The limit on elective deferrals.
Depending upon the type of contributions made to your 403(b) account, only one of the limits may apply to you.
taxmap/pubs/p571-009.htm#en_us_201212_publink1000239632Whether you must apply one or both of the limits depends on the type of contributions made to your 403(b) account during the
year.
taxmap/pubs/p571-009.htm#en_us_201212_publink1000239633If the only contributions made to your 403(b) account during the year were elective deferrals made under a salary reduction agreement, you will need to figure both of the limits. Your MAC is the lesser of the two
limits.
taxmap/pubs/p571-009.htm#en_us_201212_publink1000239634If the only contributions made to your 403(b) account during the year were nonelective contributions (employer contributions not made under a salary reduction agreement), you will only need to figure the limit on annual additions. Your MAC is the limit on annual
additions.
taxmap/pubs/p571-009.htm#en_us_201212_publink1000239635If the contributions made to your 403(b) account were a combination of both elective deferrals made under a salary reduction agreement and nonelective contributions (employer contributions not made under a salary reduction agreement), you will need to figure both limits. Your MAC is the limit on the annual
additions.
You need to figure the limit on elective deferrals to determine if you have excess elective deferrals, which are explained in
chapter 7.
