Final answer:
When a business is operated as an S corporation, a disadvantage is that the shareholder must pay taxes on their share of the corporation's income regardless of distribution.
Step-by-step explanation:
When a business is operated as an S corporation, a disadvantage is that the shareholder must pay the tax on his or her share of the S corporation's income even though the S corporation did not distribute the income to the shareholder. This is known as pass-through taxation. Unlike a C corporation, where the corporation pays taxes on its income and then shareholders pay taxes on dividends received, in an S corporation the income is passed through to the shareholders who pay taxes on it regardless of whether it is distributed or not.
