S and C Corporations
There are several types of corporations. The main two are the S corporation and C corporation (S and C are subsections of the IRS Code). While there are several differences between the S and C corporations, there are two main ones.
The first is that C corporations are taxed twice: once when profits are realized, and a second time when those profits are passed on to the shareholders. The advantage of the S corporation is it does not pay a corporate tax at all; instead, its shareholders report profits and losses on their personal tax returns, and therefore, profits are taxed only once.
Another difference between the two has to do with size. For the most part, C corporations are large, publicly traded businesses. When you see a business whose shares are bought and sold on the New York Stock Exchange, that is a C corporation. In fact, the ability to freely sell shares is one of the main advantages of a C corporation. People who start businesses with an exit strategy of going public start C corporations. While most large businesses are C corporations, some small businesses choose this form of structure as well for one very good reason: C corporations can deduct 100 percent of the health insurance costs for its employees (including you).
The double-taxation whammy of the C corporation pushes many small business owners toward S corporations, which are, generally speaking, intended for and used by smaller businesses. There are certainly more pros than cons to starting your small business as an S corporation:
• S corporations offer limited personal liability.
• S corporations pay no corporate taxes. Again, profits and losses flow through to your individual tax return.
• A sole owner of an S corporation does not have to pay the FICA tax—Medicare and the self-employment tax, which are roughly 15 percent on the first $75,000 you earn.
• The bad news is that there are restrictions on S corporations: You can have no more than 75 shareholders, and you cannot have any preferred stock.
Another sort of corporation is called the professional corporation. This type is for the professionally licensed small business owner only, and that professional can be the only shareholder. The type of professional who can take part in this plan varies by state, but usually includes lawyers, doctors, dentists, accountants, and psychologists. It is important to understand that this sort of corporation cannot normally shield you from a malpractice award.
