LLC vs Sole Proprietorship – What is the difference?

Choosing between an LLC and a sole proprietorship is one of the first decisions you’ll make as a business owner. Both let you operate legally and earn income, but they differ in liability protection, taxes, cost, and paperwork.

Here’s the short version: a sole proprietorship is the simplest structure — you start doing business and that’s it. An LLC (limited liability company) requires state registration but separates your personal assets from your business debts. Most business owners who face any real liability risk should form an LLC.

Below, we break down every meaningful difference so you can make the right call.

LLC vs Sole Proprietorship at a Glance

What Is an LLC?

An LLC is a business structure you register with your state by filing Articles of Organization. Once formed, the LLC exists as a separate legal entity from its owner (called a “member”).

The most important thing an LLC does is create a legal wall between your personal assets and your business. If someone sues your LLC or the business can’t pay its debts, your personal bank accounts, home, and car are generally off-limits. This is called limited liability protection.

An LLC is taxed as a pass-through entity by default. Profits flow through to your personal tax return — the LLC itself doesn’t pay federal income tax. But unlike a sole proprietorship, an LLC can also elect to be taxed as an S-Corp, which can save you money on self-employment taxes once your income is high enough.

You can form an LLC in any state. Filing fees range from $50 to $500, and most states require an annual report or franchise tax to keep the LLC in good standing.

What Is a Sole Proprietorship?

A sole proprietorship is the default business structure for any individual who starts earning income from a business activity. There’s nothing to file — no state registration, no formation documents. If you freelance, sell products online, mow lawns for money, or do any other business activity on your own, you’re already a sole proprietor.

The simplicity is the main advantage. You report business income and expenses on Schedule C of your personal tax return, and that’s essentially it.

The major downside: there’s no separation between you and your business. If someone sues your business or you rack up business debts you can’t pay, your personal assets — savings, home, vehicles — are fair game. You are the business, legally speaking.

If you want to operate under a business name (anything other than your legal name), you’ll need to file a DBA (doing business as) with your county or state.

Key Differences Between an LLC and a Sole Proprietorship

Liability Protection

This is the single biggest reason to form an LLC.

As a sole proprietor, you have unlimited personal liability. If your business is sued, a creditor can go after your personal bank accounts, your home equity, your car, and your investments. There is no legal distinction between you and your business.

An LLC creates that distinction. Your personal assets are generally protected from business lawsuits and debts. A creditor can go after the LLC’s assets — business bank accounts, equipment, inventory — but not your personal property.

This matters even for low-risk businesses. A single slip-and-fall at a client’s location, a product liability claim, or an unpaid vendor could expose your personal finances.

Note: LLC protection isn’t absolute. Courts can “pierce the corporate veil” if you commingle personal and business funds, fail to maintain the LLC properly, or personally guarantee a debt. Keep your finances separate and your LLC in good standing.

Taxes

By default, both structures are taxed the same way: as pass-through entities. Business income flows to your personal return, and you pay income tax at your individual rate plus self-employment tax (Social Security and Medicare) of 15.3% on net earnings.

The LLC’s tax advantage is flexibility. A single-member LLC can elect to be taxed as an S-Corporation. With an S-Corp election, you pay yourself a “reasonable salary” and take remaining profits as distributions — which are not subject to self-employment tax.

Tax Example: Sole Proprietorship vs LLC (S-Corp)

Say your business earns $120,000 in net profit.

In this example, the S-Corp election saves roughly $7,776 per year in self-employment taxes. The savings grow as your income increases. Generally, the S-Corp election starts making sense when your net business income exceeds $50,000–$60,000 per year, after accounting for the added payroll and accounting costs.

A sole proprietorship cannot elect S-Corp taxation. That option is only available to LLCs and corporations.

Formation and Paperwork

Sole proprietorship: No formation paperwork. You may need a local business license or DBA filing, but there’s nothing to register with the state.

LLC: You must file Articles of Organization (sometimes called a Certificate of Formation) with your state’s Secretary of State office. This typically requires:

• A unique business name that includes “LLC” or “Limited Liability Company”
• A registered agent — a person or service with a physical address in the state to receive legal documents
• Payment of the state filing fee
• An operating agreement (required in some states, recommended in all)

Most states also require an annual report or biennial filing to keep the LLC active, plus any applicable franchise taxes.

Cost

A sole proprietorship costs $0 to start (unless your city or county requires a business license, typically $25–$100).

An LLC costs more upfront and ongoing:

In most states, you can form an LLC for under $200 total. The ongoing costs are typically $50–$300 per year. For the liability protection and tax flexibility you get in return, most business owners find this well worth it.

Business Name

As a sole proprietor, your legal business name is your personal name. To operate under a different name, you need to file a DBA. A DBA doesn’t provide liability protection or any legal structure — it’s just a registered alias.

An LLC has its own legal name, registered with the state. You can open bank accounts, sign contracts, and do business under that name without any additional filings.

Credibility

An LLC carries more credibility with clients, vendors, banks, and partners. Having “LLC” in your business name signals that you’ve taken the step to formalize your business. This can matter when:

• Applying for business loans or lines of credit
• Bidding on contracts (many companies require vendors to be a registered entity)
• Negotiating with suppliers
• Attracting partners or co-owners

A sole proprietorship, by contrast, can look informal — especially if you’re operating under just your personal name.

Ownership and Growth

A sole proprietorship is limited to one owner. If you want to bring on a partner or co-owner, you’ll need to form a different entity (like an LLC or partnership).

An LLC can have one member (single-member LLC) or multiple members (multi-member LLC). You can add members, create different ownership classes, and structure profit-sharing however you want in the operating agreement. This makes an LLC far more flexible if your business grows.

When to Choose a Sole Proprietorship

A sole proprietorship makes sense when:

• You’re testing a business idea and want to start earning income immediately with zero cost or paperwork
• The liability risk is very low — you’re freelance writing, tutoring, or doing work where lawsuits are unlikely
• Income is minimal — if you’re making under $10,000–$20,000 per year, the LLC costs may not be justified
• It’s a side hustle that you don’t plan to grow into a full business

Even in these cases, consider that a single lawsuit or debt collection action could wipe out your personal savings. Many business advisors recommend forming an LLC as soon as your income justifies the cost.

When to Choose an LLC

An LLC is the better choice when:

• You have personal assets to protect — a home, savings, investments
• Your business involves any liability risk — client work, physical products, services at client locations, handling data
• You earn enough to benefit from S-Corp taxation — generally $50,000+ in annual net profit
• You want to build business credit separately from your personal credit
• You plan to grow — add partners, hire employees, seek investment
• You need credibility — contracts, bank accounts, vendor relationships

For most serious businesses, an LLC is the right starting point. The cost is low, the protection is significant, and you can always upgrade to a corporation later if needed.

LLC vs Sole Proprietorship for Specific Situations

Real Estate and Rental Properties

If you own rental property, an LLC is almost always the right choice. A tenant injury, property damage claim, or landlord-tenant dispute could put your personal assets at risk. Many real estate investors create a separate LLC for each property to isolate liability between them. See our guide on starting an LLC for rental property.

Online Businesses and E-Commerce

Selling products online — whether through your own store, Amazon FBA, or Shopify — creates product liability exposure. If a product injures someone, the seller can be sued. An LLC protects your personal assets from these claims. It also adds credibility with suppliers and wholesale vendors who often prefer working with registered businesses.

Gig Workers and Delivery Drivers

DoorDash, Uber, Instacart, and other gig platforms treat you as an independent contractor — which means you’re a sole proprietor by default. While the platform’s insurance provides some coverage, it may not cover everything. An LLC can add an extra layer of protection, and the S-Corp election can save you thousands in self-employment taxes if your gig income is substantial. See our guide on starting an LLC for DoorDash.

Consultants and Professional Services

Consultants, coaches, designers, developers, and other service providers face potential liability from client disputes, missed deadlines, or errors in deliverables. An LLC won’t protect you from your own professional malpractice (you need professional liability insurance for that), but it does protect your personal assets from general business debts and contract disputes.

How to Convert a Sole Proprietorship to an LLC

If you’ve been operating as a sole proprietor and want to upgrade, the process is straightforward:

1. Choose your state and check name availability
2. File Articles of Organization with the Secretary of State
3. Get an EIN (Employer Identification Number) from the IRS — free, takes 5 minutes online
4. Open a business bank account in the LLC’s name
5. Create an operating agreement (even for a single-member LLC)
6. Update licenses, contracts, and vendor accounts to reflect the LLC
7. Separate your finances — stop running business expenses through personal accounts

The entire process can be done in a day for most states. See our step-by-step guide to starting an LLC for detailed instructions.

Frequently Asked Questions

Do sole proprietors pay more taxes than LLC owners?

Not by default. A single-member LLC and a sole proprietorship are taxed identically — both use Schedule C and both pay 15.3% self-employment tax. However, an LLC can elect S-Corp taxation, which can significantly reduce self-employment taxes for higher earners. A sole proprietorship cannot make this election.

At what income level is an LLC worth it?

From a tax perspective, the S-Corp election typically starts saving money at $50,000–$60,000 in annual net profit. But liability protection alone makes an LLC worth it at any income level if you have personal assets at risk. Many states let you form an LLC for under $100.

Can I switch from a sole proprietorship to an LLC?

Yes. You can convert at any time by filing Articles of Organization with your state. You’ll need a new EIN, a business bank account, and an operating agreement. The process takes a few days in most states.

Does an LLC protect my personal assets?

Yes. An LLC separates your personal assets (home, car, savings) from business liabilities. If your business is sued or can’t pay its debts, creditors can only go after the LLC’s assets — not yours. You must maintain the separation by not commingling personal and business funds.

What are the disadvantages of an LLC?

The main disadvantages are cost and paperwork. You’ll pay a state filing fee ($50–$500), possible annual fees, and need to maintain basic records. In California, there’s an $800 annual franchise tax regardless of income. Some states also require published notices. For most business owners, these costs are minor compared to the liability protection.

Can a sole proprietor have employees?

Yes, but it’s risky. As a sole proprietor with employees, you’re personally liable for everything — workplace injuries, employee lawsuits, payroll obligations. If you’re hiring employees, forming an LLC first is strongly recommended.

Is an LLC better than a sole proprietorship for freelancers?

For most freelancers, yes. An LLC protects your personal assets from client disputes, contract claims, or errors and omissions. The exception might be very low-income freelancers in low-risk fields where the $100–$200 annual LLC cost isn’t justified by the income.

What happens to a sole proprietorship if the owner dies?

A sole proprietorship ceases to exist when the owner dies. There’s no separate entity to transfer. The business’s assets and debts become part of the owner’s estate. An LLC, by contrast, can include succession provisions in its operating agreement, allowing the business to continue under new ownership or be transferred to heirs.

Do I need a lawyer to form an LLC?

No. Most people file on their own or use an LLC formation service. The process involves filling out a form with the Secretary of State, paying the filing fee, and creating an operating agreement. A lawyer can be helpful for multi-member LLCs or complex ownership structures, but isn’t required for a standard single-member LLC.

The Bottom Line

A sole proprietorship is fine for testing a business idea or running a very low-risk side hustle. But the moment your business generates meaningful income or involves any liability exposure, an LLC is worth the small investment.

For most business owners, the calculus is simple: a few hundred dollars per year for an LLC buys you liability protection that could save you everything you own. Add in the tax flexibility of the S-Corp election, the credibility boost, and the ability to grow the business with partners, and the LLC is the clear winner for anyone running a real business.
