Sole Proprietorship vs LLC: Which Is Right for You?

A sole proprietorship is the simplest business structure in the United States. You become one automatically the moment you start earning business income. There is no state filing, no formation document, and no registration fee.

The IRS treats you and the business as a single tax entity. You report all business income and expenses on Schedule C of your personal Form 1040. You pay 15.3% self-employment tax on net profit (12.4% Social Security + 2.9% Medicare, as of 2026).

The biggest drawback? You have zero liability protection. If someone sues your business or you can't pay business debts, creditors can go after your personal bank accounts, your home, and your car. There is no legal separation between you and the business.

Some states and cities require a business license or DBA filing to operate under a business name. A DBA typically costs $10 to $50 and takes a few days to process. That may be your only required paperwork.

A limited liability company (LLC) is a state-registered business entity that separates your personal assets from your business liabilities. You form one by filing Articles of Organization (sometimes called a Certificate of Formation) with your state's Secretary of State.

Filing fees range from $35 to $500 depending on the state. California charges $70, Florida charges $125, Texas charges $300, New York charges $200 (plus $300 to $1,500 for mandatory newspaper publication), and Delaware charges $90. Processing typically takes 3 to 10 business days, though many states offer same-day or 24-hour expedited options.

By default, a single-member LLC is taxed exactly like a sole proprietorship (Schedule C). But here is the key advantage: an LLC can elect to be taxed as an S Corporation or C Corporation by filing IRS Form 2553. That flexibility is not available to sole proprietors.

LLCs can have unlimited members (owners), including other businesses and foreign nationals. You define how profits are split and how decisions are made through an operating agreement, an internal document you draft but typically do not file with the state.

Five dimensions matter most when you compare a sole proprietorship to an LLC. Here they are, ranked by the order most readers care about.

How Each Structure Is Taxed

Both structures default to pass-through taxation. That means business profit flows to your personal return and you pay income tax plus 15.3% self-employment tax on net earnings. For 2026, the Social Security portion (12.4%) applies to the first $184,500 of combined wages and self-employment income. The Medicare portion (2.9%) applies to all earnings with no cap.

The critical difference is tax election flexibility. A sole proprietor is locked into Schedule C treatment. An LLC owner can file IRS Form 2553 to elect S Corp taxation. With S Corp status, you split income between a reasonable salary (subject to payroll tax) and distributions (not subject to SE tax). On $100,000 in net profit, this split can save roughly $5,000 to $8,000 per year in self-employment tax.

Liability Protection Compared

A sole proprietorship provides zero liability protection. If a customer sues or you default on a business lease, creditors can seize your personal home, car, bank accounts, and investments. There is no legal wall between you and the business.

An LLC creates that wall. Your personal assets are protected as long as you maintain the "corporate veil" by keeping business and personal finances separate, signing contracts in the LLC's name, and maintaining your state compliance filings. If you commingle funds or treat the LLC as a personal piggy bank, a court can "pierce the veil" and hold you personally liable.

Formation and Paperwork Requirements

Starting a sole proprietorship requires nothing in most states. You may need a local business license ($25 to $100) or a DBA filing ($10 to $50) if you operate under a name other than your own legal name.

Forming an LLC requires filing Articles of Organization with your state. Here is what the top 5 states charge:

• California: $70 filing fee (plus $800/year franchise tax)
• Texas: $300 filing fee (no annual report fee for most LLCs)
• Florida: $125 filing fee ($138.75/year annual report)
• New York: $200 filing fee (plus $300 to $1,500 publication requirement)
• Delaware: $90 filing fee ($300/year annual tax)

Management and Ownership Flexibility

A sole proprietorship is limited to one owner. You cannot add a partner, sell equity, or bring in investors without changing your business structure entirely.

An LLC can have unlimited members. Members can be individuals, other LLCs, corporations, or foreign nationals. You choose between member-managed (all owners share control) or manager-managed (one or more designated managers run daily operations). All of this is documented in your operating agreement.

Ongoing Compliance Obligations

Sole proprietors have minimal ongoing requirements. File your tax return. Renew any local licenses. That is about it.

LLCs must file annual (or biennial) reports with their state, maintain a registered agent, keep an operating agreement on file, and pay any state-specific fees. Annual report fees range from $0 (Texas) to $300 (Delaware). As of March 2026, FinCEN's interim final rule exempts U.S.-formed entities from federal Beneficial Ownership Information (BOI) reporting, though this could change when the final rule is issued.

Sole Proprietorship Pros and Cons

The sole proprietorship's biggest selling point is simplicity. Zero paperwork, zero cost, and the easiest tax filing in the business world. If you are testing a business idea with minimal risk, it is the fastest way to start.

• Pro: No formation filing and $0 startup cost
• Pro: Simplest tax filing (Schedule C on your 1040)
• Pro: Full decision-making control with no legal formalities
• Pro: Easy to convert to an LLC later if you outgrow it
• Con: No liability protection for your personal assets
• Con: Cannot elect S Corp tax treatment
• Con: Harder to build business credit or get business loans
• Con: Cannot bring in partners or investors

LLC Pros and Cons

The LLC gives you the liability protection of a corporation with the tax simplicity of a sole proprietorship. It is the most popular business structure for a reason.

• Pro: Personal assets protected from business lawsuits and debts
• Pro: Tax flexibility with S Corp or C Corp election options
• Pro: Unlimited members with customizable profit splits
• Pro: Stronger credibility with banks, vendors, and clients
• Pro: Operating agreement lets you tailor management structure
• Con: Formation costs $50 to $500 depending on state
• Con: Ongoing annual fees (California's $800/year franchise tax is the worst)
• Con: Requires registered agent, annual reports, and basic recordkeeping
• Con: Slightly more complex to dissolve than a sole proprietorship

Your decision comes down to three factors: how much you earn, how much risk you carry, and whether you plan to grow. Use these if/then scenarios to find your answer.

If you earn under $30,000/year with low liability risk (online freelancing, tutoring, consulting from home), start as a sole proprietor. Your overhead stays at $0, and you can convert to an LLC anytime.

If you earn $40,000 to $80,000/year, an LLC is worth the formation cost for liability protection alone. At this income level, the S Corp election typically does not save enough to justify the extra compliance cost ($1,500 to $3,000/year for payroll and accounting).

If you earn over $80,000/year in net profit, forming an LLC and electing S Corp status is almost always the right move. You will likely save $5,000 to $15,000/year in self-employment tax, which more than covers the added compliance cost.

If you have personal assets worth protecting (a home, retirement savings, investment accounts), form an LLC regardless of income. The $50 to $300 formation fee is the cheapest liability insurance you will ever buy.

If you serve the public in person (food truck, retail store, fitness training, landscaping), form an LLC. Physical businesses carry slip-and-fall, product liability, and property damage risk that can wipe out personal savings.

If you want to bring in a partner or investor, you need an LLC. Sole proprietorships are limited to one owner. An LLC operating agreement lets you define ownership percentages, profit splits, and decision-making authority.
