C-Corporation.

The venture-backed startup default. Shares, stock options, board.

A C-corp is the standard entity for raising venture capital. Its shares can be sliced into preferred and common classes, issued as options, and owned by foreign investors — all features VCs require. The trade-off is double taxation and real governance overhead.

How the IRS sees this entity.

Double taxation

Entity taxed + dividends taxed (double)

The corporation pays tax on profit (currently 21% federal). Distributed dividends are then taxed again on the shareholder's personal return. The trade-off for raising venture capital.
