The organization, operation, and taxable sales and liquidations are studied on a comparative basis, first looking at C corporations, then partnerships, and then S corporations. The last area, reorganization, pertains only to corporations. The final chapter in each part focuses on the tax policy aspects of the particular topic. The overall structure of the book should facilitate a comparison of the doctrines governing the taxation of the three forms and thereby give the student an enhanced understanding of the policy rationales underlying our system of business taxation.
