Legal Frameworks Governing US Corporations

1. Types of US Business Structures

Selecting the right structure determines your tax obligations, ownership rules, governance, and long-term scalability.

C Corporation (C-Corp)

Common for businesses planning to scale, raise investment, or go public. Offers strong liability protection but is subject to corporate income tax.

S Corporation (S-Corp)

Ideal for small and medium-sized businesses meeting IRS requirements:

• Maximum 100 shareholders

• Shareholders must be US citizens or US residents

• Only one class of stock

S-Corps offer pass-through taxation, allowing profits to be taxed only at the shareholder level.
