LLC vs Sole Proprietorship: How to Choose When You're Just Getting Started

Forming an LLC will not lower your income taxes, and not forming one does not make your business illegal. If you have been selling or freelancing on your own without registering anything, you are already a sole proprietor. So the LLC vs sole proprietorship question comes down to two trade-offs: how much of your own money is on the line if something goes wrong, and how much paperwork you are willing to take on.

This is general information, not legal or tax advice. State rules differ, so confirm yours before you file anything.

A sole proprietorship is what you are by default

According to the U.S. Small Business Administration (SBA), you become a sole proprietor by default when you run a business and don't register as any other kind of business. There's no separate business entity, which means you can be held personally responsible for the debts and obligations of the business.

That doesn't mean zero paperwork. Depending on where you live and what you do, you may still need a local business license, permits, or a registered trade name if you operate under something other than your legal name. Working from home can bring zoning questions, too.

An LLC (limited liability company) is different because you create it by filing with your state. It becomes its own legal entity that can hold assets and sign contracts, and you own it as a member. With one owner, it's a single-member LLC. With two or more, it's a multi-member LLC.

The table below compares the two.

Liability is the real difference, and it shows up in contracts

The SBA says LLCs protect you from personal liability in most instances, which is the main reason people form one. If your business owes money or gets sued, your personal assets are generally shielded. As a sole proprietor, they are not.

Say you're a freelance designer who signs a contract promising a client a full brand rollout by a certain date. If you miss it and the client claims losses far bigger than your fee, a sole proprietorship leaves you personally exposed. An LLC adds a layer between that claim and your savings.

The protection has limits, though:

• Personal guarantees cancel it out. If you personally guarantee a lease or a loan, you're on the hook even with an LLC.
• Your own mistakes are still yours. An LLC doesn't shield you from responsibility for your own wrongful acts.
• Mixing money can weaken it. If you treat the LLC like a personal wallet, a court may decide it isn't really separate. State law controls how this plays out.

An LLC also doesn't replace insurance. The LLC creates legal separation, while insurance pays for covered losses. Depending on what you do, you may want both. Read the exclusions before you assume a policy covers the work you're actually doing.

If you're not sure how risky your work is, ask two questions. What is the worst thing that could happen if a customer or client is unhappy? And what would I owe if I couldn't deliver? Selling products people put on their skin or use with kids carries different exposure than writing newsletters.

Your federal income taxes probably look the same either way

The IRS says a single-member LLC is, by default, treated as an entity disregarded as separate from its owner for income tax purposes. That means the income and expenses go on your own return, the same way a sole proprietor's do. The IRS says a single-member LLC owned by an individual generally reports on Schedule C, the same profit-or-loss schedule sole proprietors use, and the owner owes self-employment tax on net earnings just as a sole proprietor would.

Forming an LLC doesn't, on its own, lower your taxes. Plan for self-employment tax and possible quarterly estimated payments either way. This Girlboss guide to turning a side hustle into a full-time business covers estimated taxes alongside setup basics.

Where taxes do change:

• Multiple owners. The IRS says a domestic LLC with two or more members is classified as a partnership by default, and partnerships generally file Form 1065. If you're launching with a partner, talk through who funds the tax bill, because your share of taxable income isn't always the cash you take home. Our piece on starting a business with your partner covers the people side of that conversation.
• Electing corporate treatment. An LLC can choose to be taxed as a corporation by filing Form 8832, according to the IRS page on LLCs filing as a corporation or partnership. Some owners also look at an S corporation election later, once profits are steady. That adds payroll and extra returns, so it's a conversation for an accountant, not a first-week decision. The SBA describes S corp status as a tax election, not a separate type of business.
• Employment and excise taxes. The IRS says a single-member LLC is treated as a separate entity for employment taxes and certain excise taxes, so those filings use the LLC's own name and EIN.

The paperwork gap is real but smaller than the liability gap

For a sole proprietor, the to-do list is mostly local: licenses, permits and a trade-name registration if you use one. For an LLC, you'll typically also:

• File formation paperwork with your state, commonly called articles of organization, and pay the state's filing fee.
• Name a registered agent to receive legal documents on the LLC's behalf.
• Create an operating agreement. State requirements for one vary, but it's smart to have one, especially with more than one owner.
• Keep up with annual or periodic reports and any state taxes. These are not on the same schedule everywhere.

The SBA notes that filing requirements for each business structure can vary by state, and that you'll probably need to register in any state where you conduct business. Costs also vary, so check your own state's filing office for current fees instead of trusting a number from an old article.

Decide who will track due dates. If you pay a service to handle filings, confirm exactly what it covers and what stays on your plate.

If you form an LLC, run its income and spending through its own account. That keeps your records clean and supports the separation the LLC is meant to create. When you pay an LLC expense out of pocket, document it and reimburse yourself.

Match the setup to your situation

There's no universal right answer, but there are patterns.

You're testing an idea on the side. If the risk is low, you're working alone and the stakes are small, a sole proprietorship is a reasonable place to start. Revisit the decision when you take on bigger contracts or add new activities. Our guide to working a side hustle without losing your day job can help you pace that stage.

You freelance. Read your contracts. Look at the scope, indemnity clauses and any cap on damages. If you handle confidential information or work that touches a client's money, weigh that risk seriously. An LLC plus professional insurance can cover different parts of the exposure.

You sell physical products. Customer injury and property damage are real possibilities, and so are safety rules and the claims you make about the product. An LLC and suitable product liability coverage are worth discussing before you take orders.

You're hiring or adding an owner. Employees bring payroll and workplace obligations. A co-owner changes ownership and tax reporting, and you'll want everyone's authority, contributions and exit terms in writing from the start.

Switching later is possible, but it takes planning

Many owners start as sole proprietors and form an LLC when the business grows. Filing is only step one. Afterward, you'll need to update everything attached to your old setup: client contracts, accounts, licenses and permits, insurance, and where payments go.

Two warnings. First, forming an LLC doesn't erase debts or liabilities you took on personally before it existed, unless a valid agreement releases you. If you want the LLC to take over a contract or loan, ask the other party what consent and paperwork they need, and get any release in writing. Second, check how the change affects your tax ID before you change what's on accounts or forms.

Before you commit to anything, our self-employment checklist and the walkthrough on how to create a business plan will help you check that the rest of the foundation is solid.

Write down your worst case this week

Write down the worst realistic thing that could go wrong in your business and what you'd owe if it did. If the answer is small and you work alone, a sole proprietorship can be a sensible start. If it makes you uncomfortable, or you're about to sign something big, take your contracts to an attorney and ask whether an LLC makes sense in your state. Put a reminder in your calendar to revisit the choice when your work changes.

Frequently Asked Questions

Does registering a DBA protect my personal assets?

No. A DBA, or "doing business as" registration, lets you operate under a trade name where one is required. You're still a sole proprietor and still personally responsible for the business. Only a separate legal entity, formed under your state's rules, changes the liability picture.

Can a sole proprietor hire employees?

Yes. You don't need an LLC to hire. You will need to meet employer obligations, which can include getting an EIN, registering for payroll taxes and following workplace and workers' compensation rules in your state. Check with your state labor or tax agency before your first hire.

Do I need a new EIN if I form an LLC?

Maybe. The IRS says a single-member LLC with employees needs its own EIN, and it also treats the LLC as a separate entity for certain excise taxes. One with no employees or excise taxes can generally use the owner's information for federal income tax, but your bank or state may still ask for an EIN. Check the IRS guidance for your situation before applying.

Can I form my LLC in a different state from where I live?

You can, but if you actually do business from your home state, you may also have to register the LLC there as a foreign entity, which can mean extra filings and fees in both places. Compare both states' rules before you choose.

Is an S corporation an alternative to an LLC?

Not quite. S corporation is a tax status, not a type of business entity. An eligible LLC can elect it and remain an LLC under state law, while a corporation is a different state-law entity altogether. Ask an accountant whether electing S status makes sense for your profit level.
