The Act to Modernize Corporate Income Tax Law is intended to eliminate the differences that currently exist in the taxation of partnerships and corporations.

This newsletter article outlines the key points of the planned option model and also contains an initial assessment of the constellations in which the change of taxation system may be advantageous.
