C Corporation Taxation

REG

A C corporation is taxed as its own entity, separate from its owners, and that single fact drives everything else in this topic: the flat tax rate, the double taxation of dividends, and the two-tier treatment of dividend income depending on what kind it is.

Why does a C corp get taxed twice?

The corporation pays tax on its own income first. When it distributes that after-tax income to shareholders as a dividend, the shareholders pay tax on it again. That's double taxation, and it's the defining feature that separates a C corp from a passthrough entity like an S corp or partnership, where income is taxed once, at the owner level.

What rate does a C corp pay?

A flat 21% on all taxable income, no matter the source. Unlike individual rates, there's no bracket structure: ordinary income and capital gains are taxed at the same flat rate.

How are dividends taxed differently depending on type?

Dividend typeTaxed at
Ordinary dividendThe shareholder's marginal (ordinary income) tax rate
Qualified dividendThe shareholder's capital gains rate

Whether a dividend qualifies depends on holding-period and payer requirements set by the IRS, not on how the corporation labels it. That distinction is what makes qualified dividends meaningfully cheaper for a shareholder than ordinary ones.
