Businesses incorporate primarily for protection: protection of the owners of the company from the liabilities of the business. Both corporations and limited liability companies legally separate the owners/investors of a company from their company’s liabilities. Further, incorporation of either a corporation or an LLC may provide tax benefits, prestige and/or name protection, as well as possibly making it easier to set up health insurance, retirement plans and other benefits to owners and employees.
A corporation is a legal entity that exists separately from its owners. Creation of a corporation occurs when properly completed articles of incorporation (called a charter or certificate of incorporation in some states) are filed with the proper state authority, and all fees are paid.
In the US tax code, a corporation is a C corporation by default. Because it is separate from its shareholders, it pays its own taxes based on its own income. No one is entitled to take money from the corporation unless it is a payment for services rendered, for salary or bonus, or as a dividend. Income remaining after deductions for expenses and depreciation are taxed by the federal government and perhaps also by state governments. What’s left after this is available to build up capital in the corporation or to give to the shareholders as dividends.
If a corporation has 100 or fewer shareholders, all of whom are US residents for tax purposes and either human beings or qualified trusts, it can elect to be treated as an “S” corporation and avoid corporate taxation. For many shareholders, this status lets them avoid double taxation.
An LLC is an entity that combines features of partnerships and corporations. It combines the advantages of limited liability (like a corporation) with the pass-through taxation and structural flexibility of partnerships.
A nonprofit corporation is a corporation that is formed pursuant to a different law than a standard for-profit corporation. The corporation must be formed for a religious, charitable, educational, literary, scientific or other non-business purpose. While a standard business corporation is designed to benefit and generate a profit for its shareholders, nonprofits do not have the profit motive. Nonprofit corporations are allowed to apply for tax-exempt status at both the federal and state level.
Each entity has its advantages and disadvantages, so which entity to choose depends on what the company intends to do.
