The legal structure you choose for your business determines your personal liability exposure, how your profits are taxed, the administrative complexity you must manage, and your ability to raise outside capital. This decision has lasting consequences that are difficult and expensive to reverse after the fact.
What it is: The simplest business structure—no formal registration required beyond a DBA ("doing business as") filing in some states. You and your business are legally identical.
Liability: Unlimited personal liability. Every business debt, lawsuit, and obligation is your personal responsibility. A court judgment against your business is a judgment against you personally.
Taxation: All business income reported on Schedule C of your personal tax return. Subject to self-employment tax (15.3%) on net profits.
Best for: Testing a side hustle or freelance work with minimal revenue and minimal liability risk. Not suitable for any business with employees, contracts, or meaningful assets.
What it is: Formed automatically when two or more people operate a business together without formal registration. Like a sole proprietorship but with co-owners.
Liability: Catastrophic personal exposure. Each partner is jointly and severally liable for all partnership debts—meaning one partner's bad decision can make all partners personally liable, including for acts of the other partners.
Taxation: Partnership income passes through to partners' personal returns. Partners pay self-employment tax on their share of profits.
Best for: Essentially nothing. Any business with two or more people should almost always form an LLC instead of operating as an unregistered partnership.
What it is: A state-registered business entity that separates personal assets from business liabilities while offering flexible taxation options.
Liability: Members are generally protected from personal liability for business debts and lawsuits, provided corporate formalities are maintained (operating agreement, separate bank account, proper entity signage).
Taxation: Default pass-through taxation (Schedule C for single-member, Form 1065 for multi-member). Can elect S-Corp or C-Corp taxation for additional flexibility.
Best for: The majority of small and medium businesses. Provides liability protection with minimal administrative overhead. Ideal for real estate, professional services, retail, e-commerce, and most service businesses.
What it is: A tax classification—not a separate legal entity. An LLC or corporation can elect S-Corp status by filing Form 2553 with the IRS.
Liability: Same protection as an LLC (when the underlying entity is an LLC). Maintained as long as corporate formalities are observed.
Taxation: Owner-operators pay themselves a reasonable W-2 salary, subject to payroll taxes. Remaining profit distributions are not subject to self-employment tax—which is the primary advantage.
Best for: LLCs with net profits exceeding $60,000–$80,000 annually, where the self-employment tax savings outweigh the additional compliance costs (payroll service, quarterly filings, additional bookkeeping).
What it is: A separate legal entity with shareholders, a board of directors, and officers. The most complex business structure.
Liability: Strong liability protection for shareholders. Particularly useful for businesses with many investors or complex ownership structures.
Taxation: C-Corps are subject to corporate income tax at the entity level (21% federal rate). Dividends paid to shareholders are taxed again on personal returns—"double taxation." However, certain tax strategies can mitigate this.
Best for: Venture-backed startups planning to issue preferred stock and raise institutional capital. Virtually no advantage for small businesses and most service companies.
| Structure | Liability Protection | Tax Complexity | Formation Cost |
|---|---|---|---|
| Sole Proprietorship | None | Low | $0–$50 |
| General Partnership | None | Low–Medium | $0–$100 |
| LLC | Strong | Low–Medium | $40–$500 |
| S-Corp (LLC) | Strong | Medium–High | $40–$500 + payroll |
| C Corporation | Strong | High | $100–$800+ |
For the vast majority of small business owners, the LLC provides the optimal balance of liability protection, tax efficiency, and administrative simplicity. It costs more than a sole proprietorship to form but dramatically less than hiring an attorney to defend a personal liability lawsuit.
Once your LLC's net profits consistently exceed $60,000–$80,000 annually, consult with a CPA about whether the S-Corp election makes financial sense for your specific situation.
