A C Corporation and an S Corporation are exactly the same in respect to liability protection. The difference is in how you are taxed. A C Corporation has what is referred to as a double taxation. First the corporation is taxed, and secondly the dividends are taxed on the shareholders’ tax returns. An S Corporation is not taxed at the corporate level, only at the shareholder level. Most small businesses are eligible to file as S corporations. But the appropriate election must be made.
