Understanding Different Business Classifications and Their Tax Liabilities
Choosing the right business classification is one of the most important steps when starting a company. It impacts your taxes, legal liability, paperwork, and overall structure. Let’s explore the most common types — and where you can learn more.
1. Sole Proprietorship
What it is:
A sole proprietorship is the simplest and most common type of business structure. It’s an unincorporated business owned by one individual.
Tax Liability:
- Business income and expenses are reported directly on the owner’s personal tax return (Form 1040, Schedule C).
- Self-employment taxes apply.

2. Partnership
What it is:
A partnership is a business owned by two or more people who share profits and responsibilities.
Tax Liability:
- The business itself doesn’t pay taxes. Instead, profits and losses “pass through” to the partners’ personal tax returns.
- Partnerships file an information return using Form 1065 and issue K-1 forms to each partner.

3. Limited Liability Company (LLC)
What it is:
An LLC is a flexible structure that blends aspects of sole proprietorships, partnerships, and corporations. It provides liability protection for owners.
Tax Liability:
- By default, single-member LLCs are taxed like sole proprietorships.
- Multi-member LLCs are taxed like partnerships.
- LLCs can also elect to be taxed as an S-Corp or C-Corp.

4. S Corporation (S-Corp)
What it is:
An S-Corp is a tax election available to corporations and LLCs, allowing profits to pass through to the owner(s) without double taxation.
Tax Liability:
- Income, losses, deductions, and credits pass through to shareholders.
- Shareholders report income on personal tax returns.
- Must file Form 1120-S annually.

5. C Corporation (C-Corp)
What it is:
A C-Corp is a separate legal entity from its owners. It is more complex but offers strong liability protection and opportunities for raising capital.
Tax Liability:
- C-Corps pay taxes at the corporate level (Form 1120).
- Profits distributed as dividends to shareholders are taxed again on the shareholders’ returns (double taxation).
