When starting a business or restructuring an existing one, choosing the right business entity is one of the most critical decisions you’ll make. The structure you select determines how your business will be taxed, how profits are distributed, and how much personal liability you carry. The right choice can save significant tax dollars and streamline your financial operations.
In this blog, we break down the most common business entity types in the U.S.—Sole Proprietorships, Partnerships, LLCs, C Corporations (Form 1120), and S Corporations (Form 1120S)—to help you determine the best fit for your specific situation.

Sole Proprietorship
A sole proprietorship is the simplest form of business structure and is typically used by freelancers, consultants, and other small business owners. It requires no formal filing with the IRS aside from reporting income on Form 1040 with a Schedule C.
Pros:
- Easy to form and operate
- Full control by the owner
- All business income is taxed once at the individual level
Cons:
- Owner is personally liable for debts and lawsuits
- No separation between personal and business assets
- Limited ability to raise capital
Partnership (Form 1065)
A partnership involves two or more individuals or entities conducting business together. Partnerships file Form 1065 and issue Schedule K-1s to each partner for reporting income on their personal returns.
Pros:
- Pass-through taxation avoids double tax
- Flexible profit-sharing arrangements
- Relatively easy to form
Cons:
- General partners have unlimited liability
- Each partner is responsible for tax on their share of income, even if not distributed
- More complex tax reporting compared to sole proprietorship
Limited Liability Company (LLC)
LLCs are hybrid entities offering the liability protection of corporations with the pass-through taxation of partnerships or sole proprietors. LLCs can choose how they are taxed: as a disregarded entity, partnership, or even elect S or C corporation treatment.
Pros:
- Limited liability for owners (members)
- Flexible management structure
- Choice of tax classification
Cons:
- May be subject to self-employment taxes
- Varying state-level fees and rules
C Corporation (Form 1120)
C Corporations are separate legal entities taxed independently of their owners. Earnings are taxed at the corporate level and again when distributed as dividends to shareholders.
Pros:
- Limited liability for shareholders
- Greater ease of raising capital
- Access to fringe benefits and retirement plans
Cons:
- Double taxation (corporate level and dividends)
- More complex regulatory compliance
- Required formalities such as meetings and bylaws
S Corporation (Form 1120S)
An S Corporation allows income to flow through to shareholders’ individual returns, avoiding double taxation while maintaining corporate liability protection. There are strict requirements for qualification, including the number of shareholders and allowable types.
Pros:
- Pass-through taxation
- Liability protection
- Potential savings on self-employment tax
Cons:
- Strict IRS eligibility requirements
- Limit on shareholders and stock types
- Mandatory reasonable compensation for owner-employees
Key Factors to Consider When Choosing
When selecting an entity, consider the following:
- Liability: How much personal exposure are you willing to risk?
- Taxation: Do you prefer pass-through or entity-level tax?
- Funding: Will you seek outside investors?
- Flexibility: Do you want freedom in profit allocation?
- Complexity: Can you handle regulatory and filing obligations?

Changing Entities Later: Is It Possible?
Yes, a business can change its structure later, but doing so requires careful planning and may trigger tax consequences. For example:
- Converting a sole proprietorship to an LLC may be tax-free
- Converting from an S Corp to a C Corp eliminates pass-through status
- Entity changes can impact depreciation, basis tracking, and accumulated earnings
Always consult a tax advisor before making structural changes.
