What is a S Corporation?

<p>An S Corporation (S-Corp) is not a distinct business entity type on its own; rather, it is a specialized tax election made with the IRS. Both LLCs and C Corporations can apply to be treated as an S-Corp to access payroll tax optimizations while keeping their underlying structural liability safeguards active.</p>

Not Ideal For: Companies owned by foreign citizens, institutional venture funds, or entities scaling past 100 individual owners.

Tax Structure Deep Dive

<p>The primary advantage of an S Corporation is the optimization of self-employment taxes. Owners pay themselves a "reasonable salary" subject to standard payroll withholdings (Social Security & Medicare). Any remaining business distributions can be paid out as corporate dividends, which are exempt from self-employment taxes, saving thousands annually.</p>
