Chapter 9
Worksheets(p15)

Chapter 2 introduced you to the term maximum amount contributable (MAC). Generally, your MAC is the lesser of your:
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.
Pencil
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?(p15)

rule
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.

Checking the Previous Year's Contributions(p15)

rule
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.
