Whether you’re launching a small venture or planning to scale with investors, selecting the right legal structure can protect your assets, optimize your taxes, and set you up for long-term success.
This article is part of a complete Step by Step Guide called “How to Start Your Business in the United States.” To access it, click here.
Here’s a quick breakdown to help you understand your options:
Comparison of Legal Structures
Sole Proprietorship
The simplest way to get started:
– Minimal registration and setup costs
– You and the business are legally the same entity
– Unlimited personal liability: your personal assets are at risk
– Income is taxed as personal income (no separate tax return)
LLC (Limited Liability Company)
Balance between simplicity and protection:
– Creates a separate legal entity to protect personal assets
– Flexible management and moderate setup requirements (state fees between $50–$200)
– Option to be taxed as a pass-through entity (avoids double taxation)
– Added credibility with clients and partners
Corporation (C Corp or S Corp)
Best for long-term growth with investors:
– More complex structure and higher maintenance costs
– Limited liability to the capital invested
– C Corps pay taxes on profits; shareholders also pay on dividends
– S Corps allow direct income flow to shareholders (with eligibility restrictions)
Which One Should You Choose?
If you’re starting quickly with minimal costs, a sole proprietorship may be the simplest route. If you want to protect your personal assets and keep flexible tax options, consider forming an LLC. If you plan to grow with investors, issue shares, or reinvest profits, a corporation might be your best bet.

Breakdown of how Sole Proprietorships, LLCs, and Corporations are taxed in the U.S.
Sole Proprietorship
- Tax filing: Income and expenses are reported on your personal tax return (Form 1040 + Schedule C).
- Tax rate: Based on your personal income tax bracket.
- Self-employment tax: You pay the full 15.3% (Social Security + Medicare) on net earnings.
- Estimated taxes: Must be paid quarterly if you expect to owe $1,000+ in taxes.
- No separation: Business income = personal income, which can push you into a higher tax bracket.
🧾 Example: If your net profit is $80,000, you’ll owe income tax based on your bracket plus ~$12,240 in self-employment tax.
LLC (Single or Multi-Member)
- Default taxation:
- Single-member: Treated like a sole proprietorship (pass-through).
- Multi-member: Treated like a partnership (each member files a Schedule K-1).
- Tax flexibility: Can elect to be taxed as an S Corp or C Corp (more below).
- Self-employment tax: Still applies unless taxed as an S Corp.
- Qualified Business Income (QBI) deduction: May deduct up to 20% of net income (subject to limits).
🧾 Example: An LLC earning $100,000 may deduct $20,000 under QBI, reducing taxable income to $80,000.
Corporation – C Corporation
- Double taxation: The corporation pays 21% federal tax on profits, and shareholders pay tax again on dividends.
- Separate entity: Files its own tax return (Form 1120).
- No self-employment tax: But salaries paid to owners are subject to payroll taxes.
- Deductions: Can deduct fringe benefits like health insurance and retirement plans.
🧾 Example: If a C Corp earns $100,000, it pays $21,000 in corporate tax. If it distributes $79,000 as dividends, the owner pays personal tax on that too.
Corporation – S Corporation (via LLC or Corp election)
- Pass-through taxation: Income flows to owners’ personal returns (avoids double taxation).
- Salary + distributions: Owners must pay themselves a “reasonable salary” (subject to payroll tax); remaining profits can be distributed without self-employment tax.
- Tax filing: Files Form 1120-S; owners receive Schedule K-1.
🧾 Example: You pay yourself $60,000 salary (subject to payroll tax), and take $40,000 as a distribution (not subject to self-employment tax).
