An S Corporation is a corporation that has made an election (i.e., timely filed a form) to be taxed as a “pass-through”, i.e., the corporation itself is generally not taxed, but all of the taxes for profits and income, as well as for losses and expenses, are passed through to become the obligations of the individual shareholders. There are limitations to what corporations can be S Corporations. For example, S Corporations cannot be owned by more than 100 shareholders or by non-resident aliens. The “S” stands for . . . wait for it . . . small.
