Key Business Entities Explained

1. C-Corporation (C-Corp)

What It Is

A C-Corporation is a separate legal entity that pays its own taxes, independent of its owners (shareholders).

Key Tax Features

• Double taxation: Profits are taxed at the corporate level (21%) and then again when distributed to shareholders as dividends (up to 20% for qualified dividends, plus an additional 3.8% Net Investment Income Tax for high-income earners, if applicable).

• Corporations can retain profits at the corporate level, potentially at lower rates compared to individual income tax rates.

Best For

• Businesses planning to attract venture capital or go public (e.g., tech startups, high-growth companies).

• Companies wanting unlimited shareholders and flexible ownership options.

• Foreign investors, especially those who want clear separation between personal and business tax obligations.

Compliance Level

• High: C-Corps require board meetings, formal records, and adherence to corporate formalities.

2. S-Corporation (S-Corp)

What It Is

An S-Corporation is a pass-through entity, meaning profits and losses are reported directly on shareholders’ personal tax returns, avoiding double taxation.

Key Tax Features

• Single-level taxation at individual rates (10%-37%).

• Owners can receive a reasonable salary and distribute the remaining profits as distributions, which may reduce payroll taxes, particularly by lowering self-employment tax obligations.

Best For

• Small to mid-sized businesses with limited ownership (100 shareholders max), such as professional service firms, consulting agencies, and retail businesses.

• Owner-operators who want pass-through taxation with some payroll tax savings.

Important Limitation

• Only U.S. citizens and residents can be shareholders.

• Foreign investors cannot own an S-Corp.

Compliance Level

• Moderate: S-Corps have stricter rules than LLCs but fewer formalities than C-Corps.

3. Limited Liability Company (LLC)

What It Is

An LLC combines the limited liability of a corporation with flexible taxation options. It can be taxed as:

• A disregarded entity (if single-member).

• A partnership (if multi-member).

• An S-Corp or C-Corp, depending on election.

Key Tax Features

• Default taxation is pass-through: single-member LLCs are treated as disregarded entities (income reported on the owner's personal tax return), while multi-member LLCs are taxed as partnerships unless another election is made.

• Members pay tax on their share of profits, reported on personal returns.

• Self-employment tax applies to active income, but electing S-Corp status can help reduce this for owner-operators.

Best For

• Small to mid-sized businesses seeking flexibility, including real estate holdings, e-commerce ventures, and independent contractors.

• Real estate investments or holding companies.

• Foreign investors who want flexible structures and limited liability.

Compliance Level

• Low to Moderate: Fewer formalities than corporations.

4. Partnership (General Partnership or Limited Partnership)

What It Is

A partnership involves two or more owners sharing profits and losses.

• General Partnership (GP): All partners actively manage the business and have unlimited liability.

• Limited Partnership (LP): One or more general partners manage the business (with unlimited liability), while limited partners invest passively with liability limited to their investment.

Key Tax Features

• Pass-through taxation: Each partner reports their share of income on their personal tax return.

• Flexible profit and loss allocations allowed, which can be useful for estate planning or structuring special investments.

Best For

• Investment partnerships, such as private equity funds, hedge funds, or real estate ventures focusing on long-term asset appreciation.

• Family limited partnerships (FLPs) for wealth transfer and estate planning.

Compliance Level

• Moderate: Requires a partnership agreement and proper accounting for partner allocations.
