COMPUTATION OF TAX:

COR P OR AT IONS

The rules that deal w ith the computation of tax payable by corporations

are more detailed and complex than the r ules that apply to individuals.

This is because corporate taxation depends upon numerous variables:

(1) type and size of the corporation; (2) ownership structure; (3) type

and source of income; and (4) amount of income earned in a year.

net federal tax is expected to drop to 15 percent.
