LLC vs Sole Proprietorship for a Side Hustle

For most beginners, a sole proprietorship is the simplest and cheapest way to start a side hustle. An LLC makes more sense when your side hustle carries real risk (injury, property damage, client disputes, debt), when income is growing, or when you want a more professional setup. Both are taxed the same way by default, so the main trade-off is liability protection versus cost and paperwork. LLC vs Sole Proprietorship.

Side Hustle: LLC vs Sole Proprietorship

You started a side hustle, and now you’re asking whether to form an LLC. It is a fair question. Many people spend money on an LLC too early. Others skip it and later regret having nothing between their business problems and their personal savings.

This guide explains both options in plain language, shows the real differences in liability, taxes, cost, and paperwork, and helps you decide with a short checklist.

What Is a Sole Proprietorship? The Default Structure for a Side Hustle

A sole proprietorship is what you become when you earn money from a business on your own and haven’t formed any other entity. There is no registration step with the state. You and the business are legally the same person.

You report income and expenses on Schedule C of your personal tax return. If you use a business name different from your own, you may need to file a “doing business as” (DBA) name with your state or county. Your city may also require a general business license.

Pros

• Free or nearly free to start
• Very little paperwork
• Easy to close if the idea doesn’t work
• Simple tax filing

Cons

• No legal separation between you and the business
• Can look less established to some clients
• Fewer tax planning options

What Is a Single-Member LLC? A Legal Shell With Optional Tax Choices

A limited liability company (LLC) is a business entity you form by filing with your state. It exists legally apart from you. If you are the only owner, it is a single-member LLC.

By default, the IRS treats a single-member LLC as a “disregarded entity,” which means you still report income on Schedule C. So for taxes, it looks very similar to a sole proprietorship. The key difference is legal: an LLC creates a separation between your personal assets and the business’s debts and legal problems, in most cases.

Pros

• Liability protection for many business debts and claims
• More professional image
• Option to elect S corporation tax treatment later
• A clear boundary between business and personal finances

Cons

• State filing fees and, in many states, ongoing annual costs
• More record-keeping
• Protection can be lost if you mix personal and business money

Liability Protection: The Biggest Difference Between an LLC and a Sole Proprietorship

This is the main reason people form an LLC.

As a sole proprietor, you are personally responsible for business debts and legal claims. If a customer sues you or you owe a supplier money, your personal assets, such as savings, car, or home equity, could be at risk, depending on your state’s laws.

With an LLC, creditors of the business can generally go after business assets, not your personal ones. This is why many guides describe the LLC as adding a layer of protection while keeping the same simple tax setup.

But an LLC is not a magic shield. Keep these limits in mind:

• You are still responsible for your own actions. If you personally cause harm, the LLC may not protect you from that claim.
• Personal guarantees count. If you personally sign a loan or lease, you may still owe it.
• Mixing money can weaken protection. Courts may ignore the separation if you treat the LLC like your personal wallet.
• Insurance is still needed. The protection from an LLC doesn’t replace coverage for accidents and professional mistakes. See our guide on small business liability insurance in the USA.

If your hustle appears in the right column, an LLC and insurance deserve serious consideration from day one.

Taxes: LLC vs Sole Proprietorship Self-Employment Tax Explained

Many beginners assume an LLC lowers taxes. By default, it doesn’t.

Income tax: Both a sole proprietor and a default single-member LLC owner report profit on Schedule C and pay ordinary income tax on it.

Self-employment tax: Both pay it too. Self-employment tax covers Social Security and Medicare and is generally 15.3% (12.4% Social Security plus 2.9% Medicare) of net earnings. It is calculated on 92.35% of net profit, and the Social Security portion has an annual income cap. As a very rough example, $10,000 of net profit could mean around $1,400 in self-employment tax, before income tax. You can deduct half of your self-employment tax when figuring your income tax.

Estimated taxes: Because no employer withholds tax from side income, you may need to make quarterly estimated payments if you expect to owe a certain amount. Many side hustlers get surprised by a large bill at filing time.

Both structures need clean books. Track income, platform fees, and expenses such as software, supplies, and mileage. Our guide on how to estimate business startup costs can help you plan which expenses to expect.

S Corporation Election: When an LLC Can Reduce Self-Employment Tax

An LLC can choose to be taxed as an S corporation by filing IRS Form 2553. In that setup, you pay yourself a reasonable salary, which is subject to payroll taxes, and take the remaining profit as distributions, which are not subject to self-employment tax.

This can reduce taxes for some owners, but it adds costs and rules:

• You must run payroll and pay yourself a reasonable salary.
• You may need extra tax filings and accounting help.
• State rules and fees may differ.
• It usually doesn’t pay off at small profit levels.

For a freelancer netting around $45,000, some accountants say an LLC adds protection and credibility but costs more each year without reducing self-employment tax on its own. The S corporation election tends to be worth discussing as profit grows. Ask a CPA before electing it, because the right profit level depends on your state and situation.

How Much Does It Cost to Form an LLC vs Start a Sole Proprietorship?

LLC costs vary widely by state. Some states have low one-time fees, while others charge a minimum annual tax. Check your state’s business filing office for current fees before you decide.

A free EIN from the IRS is available directly. Be careful with websites that charge for it.

Paperwork and Compliance: What Each Structure Requires

Sole proprietorship

• Local business license, if required
• DBA, if you use a different name
• Sales tax registration, if you sell taxable goods or services
• Schedule C and Schedule SE at tax time

LLC

• State formation filing and registered agent
• Operating agreement
• EIN and a separate business bank account
• Annual or biennial state report and fee, in many states
• Same federal income tax forms as a sole proprietor by default

A note on federal beneficial ownership reporting: Under the Corporate Transparency Act, businesses were once expected to file beneficial ownership information (BOI) reports. As of FinCEN’s 2025 rule, entities created in the United States are exempt from this reporting requirement, and it now applies mainly to foreign entities. Rules can change, so check FinCEN’s website before forming an LLC.

When a Sole Proprietorship Is Enough for Your Side Hustle

A sole proprietorship is often fine when:

• You are testing an idea and don’t know if it will last.
• Income is small and the business has low risk.
• You work online with little chance of injury or property damage.
• You can’t yet justify state fees and extra paperwork.
• You’d rather spend the money on tools and marketing.

Even then, you can still protect yourself in other ways. Use clear written contracts, keep business money in a separate account, and consider insurance if clients or products carry risk.

When Forming an LLC Makes Sense for a Side Hustle

An LLC is worth considering when:

• Your side hustle could cause injury or damage, like food, repairs, or physical products.
• You have meaningful savings or assets to protect.
• Income is growing and may soon replace your main job.
• You sign contracts with larger clients who prefer working with a registered business.
• You plan to hire help or work with partners.
• You want to open the door to an S corporation election later.

If you’re not sure your hustle is risky enough, our guide on home-based business and small business insurance can help you think through the risks first.

Side Hustle With a Full-Time Job: Extra Things to Check: LLC vs Sole Proprietorship

Many side hustlers have a day job. Before you launch or form an LLC:

• Read your employment agreement. Look for conflict-of-interest, moonlighting, or non-compete clauses.
• Don’t use employer time or equipment. Keep the two completely separate.
• Check for competing work. Selling to your employer’s customers can cause legal trouble.
• Plan for taxes. Your day job withholds tax from your paycheck, but your side income usually has no withholding.

How to Form an LLC Step by Step for a Side Hustle

1. Check your state’s rules. Visit your Secretary of State or business filing office.
2. Choose a name. It must be available and follow your state’s naming rules.
3. Appoint a registered agent. This is the address that receives legal notices. You can often serve as your own.
4. File the formation document. Often called Articles of Organization or Certificate of Formation.
5. Create an operating agreement. A simple one-page document is still useful.
6. Get an EIN. Apply directly with the IRS.
7. Open a business bank account. Never mix personal and business money.
8. Handle licenses and taxes. Check local licenses, sales tax, and estimated payments.
9. Calendar your annual filings. Missing state deadlines can cause penalties or loss of good standing.

Can You Start as a Sole Proprietor and Form an LLC Later?

Yes. Many people start as sole proprietors and form an LLC when income and risk increase. Keep in mind:

• Protection starts when the LLC is formed, not before.
• Move your bank account, contracts, and accounts to the new LLC name.
• Update your EIN information, licenses, and any platform accounts.
• Tell clients about the change, and review any contracts for assignment rules.
• Ask a tax professional how the switch affects your tax filing that year.

Starting simple and upgrading later is a perfectly reasonable path, as long as you don’t wait until after something goes wrong.

Common Mistakes to Avoid When Choosing Between an LLC and a Sole Proprietorship

• Forming an LLC just because it sounds professional, without checking the costs
• Assuming an LLC automatically lowers your taxes
• Mixing personal and business money in an LLC
• Skipping insurance because you have an LLC
• Forgetting annual state filings and fees
• Ignoring your employment agreement
• Not tracking income and expenses from day one
• Missing quarterly estimated tax payments
• Using a paid service for a free EIN
• Never revisiting the decision as the business grows

Final Thoughts: LLC vs Sole Proprietorship

Choosing between an LLC and a sole proprietorship for a side hustle comes down to a few questions: How risky is your work? How much do you have to protect? How much are you earning? And can you afford the extra cost and paperwork? If the answers point to low risk and low income, start simple. If risk or income is rising, an LLC plus proper insurance can be a smart upgrade.

Start where you are, keep clean records, and revisit your structure as your side hustle grows.

Frequently Asked Questions:

Is an LLC or sole proprietorship better for a side hustle?

A sole proprietorship is cheaper and simpler. An LLC adds liability protection. The better choice depends on your risk, income, and budget.

Do I need an LLC for a small side business?

Not always. Many low-risk side hustles run as sole proprietorships. An LLC becomes more useful as risk and income grow.

Does an LLC save money on taxes?

Not by default. A single-member LLC is taxed like a sole proprietorship unless it elects S corporation status. That election can help at higher profit levels but adds complexity.

Do LLC owners pay self-employment tax?

Generally yes, if you actively work in the business and the LLC is taxed as a sole proprietorship or partnership.

Can I be a sole proprietor with a business name?

Yes, but you may need to register a DBA in your state or county.

Does an LLC protect my personal assets completely?

No. It generally protects against business debts and claims but not necessarily your own negligence, personal guarantees, or situations where you mix personal and business money.

Do I still need insurance with an LLC?

Often yes. An LLC and insurance protect you in different ways.

Do I have to file beneficial ownership reports for my LLC?

As of FinCEN’s 2025 rule, U.S.-created entities are exempt, but check FinCEN’s site for current rules.

Can I switch from a sole proprietorship to an LLC later?

Yes. Many side hustlers do this when their business grows.
