What is the difference between an LLC and a sole proprietorship?

A sole proprietorship is the default structure when you operate a business as an individual — no filing required, but no liability protection. An LLC is a formal legal entity that shields your personal assets from business debts and lawsuits.

If you start earning money from a side project or small business without registering anything, you're automatically a sole proprietor. There's no paperwork and no cost — but there's also no legal wall between you and your business. An LLC (Limited Liability Company) requires state registration and a small filing fee, and in exchange it creates a separate legal entity that owns the business assets and liabilities, not you personally. The SBA's guide to business structures covers this distinction in detail.

Liability: the most important difference

As a sole proprietor, your personal assets — bank accounts, car, home — are fully exposed if your business is sued or can't pay its debts. An LLC's limited liability means creditors and plaintiffs generally can't reach your personal assets to satisfy business obligations. There are exceptions (courts can pierce the corporate veil if an owner commingles funds or uses the LLC fraudulently), but in normal operations the separation holds. Consult an attorney to understand how your state treats LLC liability.

Formation, cost, and maintenance

Sole proprietorship: no filing required, no formation cost, no annual fees. You may need a DBA ("doing business as") if you operate under a name other than your own.
LLC: requires Articles of Organization filed with your state, a filing fee (typically $50–$500 depending on state), and in most states an annual report or renewal fee.
Both require the same basic business licenses and permits for your industry and locality.
LLCs typically require a registered agent to receive legal documents on the business's behalf.

Taxes: more similar than most people think

By default, both structures are taxed the same way: business income flows to your personal return and you pay self-employment tax on it. A single-member LLC is a disregarded entity for IRS purposes — it files no separate federal tax return unless it elects corporate taxation. The IRS page on LLCs outlines the default and elective tax treatments available.

Which structure do lenders prefer?

An LLC carries more credibility with lenders because it demonstrates you've formalized the business. A sole proprietorship can qualify for business financing, but you're personally liable for any debt. Either way, lenders will review your personal credit, time in business, and monthly revenue.

SBA on business structures

A sole proprietorship is the simplest business structure — the owner and the business are legally the same entity, meaning the owner is personally responsible for all debts and obligations. — SBA
An LLC protects owners from personal liability in most instances — meaning personal assets are usually protected if the business is sued or incurs debt. — SBA
A single-member LLC is treated as a disregarded entity for federal income tax purposes — it does not file a separate federal return and income is reported on the owner's personal return. — IRS

Key takeaways

Sole proprietorships require no filing but provide zero personal liability protection.
An LLC separates your personal assets from business debts — the primary reason most small business owners upgrade.
Both are taxed the same way by default: income passes through to your personal return.
An LLC costs $50–$500 to form (varies by state) and may require annual renewal fees.
From a lender's perspective, an LLC signals a more formalized operation — though both structures can qualify for business financing.
