The biggest difference between S corporations and LLCs is how they are taxed. S corporations are taxed as pass-through entities, meaning that the profits and losses are passed through to the shareholders' personal tax returns, while LLCs can choose to be taxed as either a pass-through entity or a corporation.
S corporations are considered flow through entities. The taxable income of a corporation is not subject to federal tax (although some states, including Illinois assess a tax – Illinois' S corporation tax rate is 1.5%). The income flows through to the owners and is subject to tax at the owners' tax rate.
