S Corp vs C Corp

Compare S corp and C corp tax structures — pass-through vs. double-taxed corporate income.

Overview

An S corp is a pass-through entity — profits flow to shareholders' personal returns. A C corp pays corporate tax (21%) and shareholders pay tax again on dividends. S corps avoid double taxation but have ownership and shareholder restrictions; C corps can scale and raise capital without those limits.

Our Verdict

For most profitable closely-held businesses, the S corp election (made on a regular corporation or qualifying LLC) saves taxes vs. C corp double taxation. The C corp wins if you're raising venture capital, want to retain earnings inside the company at the 21% rate, or have foreign or institutional shareholders that can't qualify under S corp rules.
