In 2026, choosing an LLC over a sole proprietorship primarily hinges on liability protection. A sole proprietorship is simple but risks personal assets, while an LLC creates a legal shield.

What Is a Sole Proprietorship and How Does It Work?

A sole proprietorship is the default, unincorporated business structure for any individual conducting trade or business alone. According to the U.S. Small Business Administration, it is the most common form, representing approximately 73% of all U.S. businesses as of 2026. There is no legal distinction between the owner and the business entity. You do not file formation documents with the state; the business exists as soon as you begin operations, such as selling crafts online or offering consulting services.

Financially, all business income and expenses are reported on Schedule C (Form 1040), attached to your personal tax return. The net profit is subject to income tax and the full 15.3% self-employment tax. Critically, there is no liability separation. You are personally responsible for all business debts, lawsuits, and obligations. For example, if a client sues your sole proprietorship for negligence and wins a $100,000 judgment, your personal savings, home, and vehicle can be seized to satisfy the debt. While some owners operate under their own name, many file a “Doing Business As” (DBA) registration with their county, which typically costs between $10 and $100 but does not confer any legal protection.

What Is an LLC and Why Do Entrepreneurs Choose It?

A Limited Liability Company (LLC) is a formal legal entity created by filing Articles of Organization with your state’s secretary of state. As a hybrid structure, it combines the pass-through taxation of a sole proprietorship with the liability protection of a corporation. The primary reason over 2.3 million new LLCs were formed in 2025 is the creation of a “corporate veil.” This legal doctrine separates your personal assets from business liabilities, meaning that in most cases, creditors can only pursue assets held in the LLC’s name.

For federal taxes, a single-member LLC is typically a “disregarded entity,” reporting taxes on Schedule C, identical to a sole proprietorship. However, an LLC offers tax flexibility: it can elect to be taxed as an S-Corporation or C-Corporation by filing IRS Form 2553 or 8832. Beyond taxes, entrepreneurs choose LLCs for enhanced credibility with clients and vendors, easier access to business banking and credit, and a clear framework for adding partners through an operating agreement. This structure signals a committed, professional operation, which is why venture capitalists and angel investors often prefer working with LLCs or corporations.
