Chapter 2 introduced you to the term maximum amount contributable (MAC). Generally, your MAC is the lesser of your:
-
Limit on annual additions (chapter 3), or
-
Limit on elective deferrals (chapter 4).
The worksheets in this chapter can help you figure the cost of incidental life insurance, your includible compensation, your
limit on annual
additions, your limit on elective deferrals, your limit on catch-up contributions, and your maximum amount contributable.
After completing the worksheets, you should maintain them with your 403(b) records for that year. Do not attach them to your
tax return. At the end
of the year or the beginning of the next year, you should compare your estimated compensation figures with your actual figures.
If your compensation is the same as, or more than, the projected amounts and the calculations are correct, then you should
simply file these
worksheets with your other tax records for the year.
If your compensation was lower than your estimated figures, you will need to check the amount contributed during the year
to determine if
contributions are more than your MAC.
When Should I Figure MAC?
At the beginning of each year, you should figure your MAC using a conservative estimate of your compensation. Should your
income change during the
year, you should refigure your MAC based on a revised conservative estimate. By doing this, you will be able to determine
if contributions to your
403(b) account should be increased or decreased for the year.
Figuring MAC for the Current Year
If you are figuring your MAC for the current year, you should use a conservative estimate of your compensation.
At the beginning of the following year, you should refigure your MAC based on your actual earned income.
At the end of the current year or the beginning of the next year, you should check your contributions to be sure you did not
exceed your MAC. This
means refiguring your limit based on your actual compensation figures for the year. This will allow you to determine if the
amount contributed is more
than the allowable amounts, and possibly avoid additional taxes.
The following worksheets have been provided to help you figure your MAC.
