S Corporations
The double taxation problem of the C corporation is eliminated, taxes on profits are paid only at the shareholder level. For tax purposes the Sub S corp is referred to as a "pass through" entity, meaning that tax liabilities pass to the shareholders. This is the major reason that Congress created the Sub S corporation status. But there is a limit to the number of shareholders and they generally must be humans. Shares cannot be held by other corporations (either C or Sub S), or by partnerships or LLCs. Trusts may hold Sub S shares but only with special provisions. Major advantages are the pass thru tax status, the ease of buying and selling stock, and the limited liability of the members.

Sub S corporations can have deductible employee stock ownership plans (ESOPs) and employee pension plans for both owners and non-owner employees. But many other employee benefits, when given to the owners of the S corporation, are not deductible to the corporation. Some disadvantages are the required annual reporting to the state and annual formalities such as shareholder and directors’ meetings, lack of privacy and franchise taxes at the state level.
