Starting a business means making decisions that will affect you for years. One of the first is how to structure your business legally. For most small business owners, the choice comes down to two options: operate as a sole proprietor or form an LLC.
Both have their advantages. But they are not the same, and the wrong choice can cost you. Here is everything you need to know to make the right call for your situation.
This article provides general educational information. Consult a licensed attorney or CPA for advice specific to your situation.
LLC vs. Sole Proprietor: Quick Comparison

| Ongoing paperwork | Minimal | Annual reports in most states |
| Personal liability protection | None | Yes (limited liability) |
| How you file taxes | Schedule C on personal return | Pass-through (default) or S-corp election |
| Business bank account required? | Not required, but recommended | Strongly recommended to maintain protection |
| Credibility with customers/banks | Lower | Higher |
| Best for | Very low-risk, early-stage testing | Most established businesses |
What Is a Sole Proprietorship?
A sole proprietorship is the default business structure. If you start selling something or offering services without forming a legal entity, you are already a sole proprietor. There is nothing to file. You and your business are legally the same thing.
The upside is simplicity. You do not need to register anything (except maybe a DBA if you use a business name). You report business income and expenses on Schedule C of your personal tax return. Most people who freelance, do odd jobs, or run a small side hustle start here.
The downside is significant: there is no separation between you and your business. If your business gets sued, your personal assets (your car, savings, home) are on the line.
What Is an LLC?
An LLC, or Limited Liability Company, is a formal legal structure you create by filing with your state. It creates a separate legal entity from you as the individual owner. That separation is the whole point.
If someone sues your LLC, they generally cannot come after your personal assets. Your liability is limited to what you have invested in the business. That is where the name comes from.
LLCs also offer tax flexibility. By default, a single-member LLC is taxed the same as a sole proprietor. But you can elect S-corporation tax treatment, which can reduce your self-employment tax burden as your income grows.
Key Differences Explained
Personal Liability Protection
This is the biggest difference. Sole proprietors have zero protection. If a customer slips and falls at your office, or a client sues you over work you did, they can go after everything you own.
An LLC creates a legal wall between your personal finances and the business. If the business is sued or goes into debt, your personal assets are generally protected as long as you maintain the separation properly (separate bank accounts, proper record-keeping, no commingling of funds).
Cost and Setup
Sole proprietors pay nothing to get started. There is no state filing required unless you want to operate under a trade name.
LLCs cost money to form. Filing fees vary by state: California is $70 (plus an $800 annual franchise tax), Texas is $300, Delaware is $90, and many states fall in the $50 to $150 range. You may also want to pay an attorney or formation service to do it correctly.
Ongoing Requirements
Sole proprietors have almost no ongoing administrative requirements. You just file your taxes each year.
LLCs require more. Most states require an annual report and fee. Some require a registered agent (which you can be yourself or hire for $50 to $150 per year). You should also maintain an operating agreement and keep business records clean.
Taxes
Both structures are pass-through for federal tax purposes by default. Business income passes through to your personal tax return. You pay self-employment tax (15.3%) on net earnings either way.
The difference comes when your income grows. LLC owners can elect S-corporation status, pay themselves a reasonable salary, and only pay self-employment tax on the salary. The rest of the profit flows through as a distribution without the self-employment tax. This can save thousands of dollars per year for high earners.
Credibility and Banking
LLCs tend to look more professional to clients, especially in B2B settings. Some clients prefer to pay invoices made out to a company name.
LLCs also find it easier to open business bank accounts and lines of credit. Banks and lenders view them as more stable than a sole proprietor operating under their personal name.
When a Sole Proprietorship Makes Sense
You are testing a new business idea and not sure if it will work. You do very low-risk work (writing, tutoring, crafts) with minimal liability exposure. You earn a small amount of income on the side and do not want the overhead. You plan to form an LLC soon but need to start immediately.
For these situations, starting as a sole proprietor is perfectly reasonable. Many successful businesses started this way before forming an LLC once they proved the model.
When You Should Form an LLC
You offer professional services where mistakes can lead to lawsuits (consulting, contracting, healthcare support). You work with clients who could claim damages if something goes wrong. You have significant personal assets you want to protect. You expect to earn more than $50,000 per year from the business. You want to look more professional and credible. You want tax flexibility as income grows.
For most serious business owners, an LLC is the right call. The annual cost is modest compared to the protection it provides.
How to Form an LLC
- Choose a state to register in (usually the state where you do business).
- Pick a name that is not already taken in that state.
- File articles of organization with the state (online in most states).
- Get an EIN (Employer Identification Number) from the IRS for free at IRS.gov.
- Open a dedicated business bank account.
- Create an operating agreement (even if not required, it is best practice).
Can You Switch from Sole Proprietor to LLC Later?
Yes. Many business owners start as sole proprietors and convert to an LLC when they are ready. The process is straightforward: form the LLC in your state, get a new EIN, open a business bank account, and notify any relevant clients or vendors. The switch does not affect your business history with clients.
Frequently Asked Questions
Do I need a lawyer to form an LLC?
No. Most people form LLCs themselves using their state’s online filing system. Services like ZenBusiness, Northwest Registered Agent, and LegalZoom can help if you want guidance. That said, consulting an attorney for an operating agreement is a good investment.
Do I pay less tax with an LLC?
Not by default. A single-member LLC is taxed the same as a sole proprietor. The tax savings come if you elect S-corp status, which only makes financial sense once you are earning a significant profit — typically above $50,000 to $80,000 per year.
Can an LLC have multiple owners?
Yes. A multi-member LLC is taxed as a partnership by default. The LLC structure works well for business partners who want to share profits and liability protection.
What is a DBA?
DBA stands for ‘doing business as.’ It is a trade name you register if you want to operate under a different name than your legal name (for sole proprietors) or your LLC’s name. A DBA does not create liability protection.
Is an LLC the same as a corporation?
No. A corporation (C-corp or S-corp) is a different legal structure with stricter requirements, shareholder structures, and different tax treatment. Most small businesses do not need a corporation unless they are seeking investment or planning to go public.
