Business Entity Selection: C-Corp vs LLC vs S-Corp

Written by Aparna Devalla, CPA

Curated by Rubric Financial

1 / 5

C-Corporation

  • Required by virtually all institutional investors (VCs, angels), allowing for preferred stock classes, unlimited shareholders, and standard equity incentive plans
  • Subject to corporate tax (21% federal) with potential double taxation on dividends, though this rarely matters for startups reinvesting all profits
  • Delaware C-corp is the default for venture-backed startups, with established case law, business-friendly courts, and investor familiarity
  • Enables ISOs, QSBS eligibility, and the standard fundraising infrastructure (SAFEs, convertible notes, priced rounds) that investors expect
