LLC vs Sole Proprietorship: Differences, Costs and Which to Choose

Admin

A side-by-side comparison of the two most common structures for US small businesses, and how to decide between them.

Quick answer: A sole proprietorship is the simplest way to run a business: there is nothing to form, but you are personally responsible for all business debts. An LLC is a separate legal entity that generally protects your personal assets from business debts and lawsuits, though it costs more to form and maintain. Both usually pass profits to your personal tax return, and both pay self-employment tax by default.

Choosing a business structure is one of the first decisions you make as an owner, and it affects your risk, your paperwork and sometimes your taxes. For most small businesses, the choice comes down to two options: stay a sole proprietor or form a limited liability company (LLC).

Neither is right for everyone. This guide compares them using guidance from the US Small Business Administration (SBA) and the IRS, with examples to help you judge your own situation. It is general information, not legal or tax advice.

How do an LLC and a sole proprietorship compare?

	Sole proprietorship	LLC
Separate legal entity	No	Yes
Personal liability for business debts	Yes, fully	Generally protected, with limits
How to form	Start trading, then get any licenses	File articles of organization with your state
Default federal tax treatment	Profits on your personal return (Schedule C)	Single-member LLC: same as sole proprietor by default. Can elect corporate tax treatment
Self-employment tax	Yes	Yes, for members by default
Startup cost	Lowest	State filing fee, plus annual fees in some states
Paperwork	Minimal	More: state reports, separate accounts, an operating agreement
Raising money	Harder	Easier than a sole proprietorship

What is a sole proprietorship?

A sole proprietorship is a business owned and run by one person with no separate legal entity. The SBA notes that it is easy to form and gives you full control. You simply start trading, then get any licenses, permits and tax registrations your business needs. If you use a brand name, you may also need a DBA.

Pros: Fast, cheap, simple taxes and full control.
Cons: Your personal assets, such as savings and possibly your home, are exposed to business debts and claims. Banks and investors are often more hesitant to fund sole proprietors.

The SBA describes it as a good fit for low-risk businesses and for owners testing an idea before they form something more formal.

What is an LLC?

An LLC is a business entity formed under state law. According to the SBA, it generally protects personal assets such as your home, vehicle and savings if the business faces bankruptcy or a lawsuit. It also keeps the flexibility of pass-through taxes by default.

Pros: Liability protection, a more professional image, and the option to elect corporate tax treatment later.
Cons: Formation and ongoing state fees, more record-keeping, and protection that can be lost if you mix personal and business money.

BTS Magazine Tip
An LLC only protects you if you treat it as separate. Use a separate bank account, sign contracts in the LLC’s name, and keep records. Paying personal bills from the business account can weaken your protection if you are ever sued.

Do LLCs pay less tax than sole proprietors?

Not automatically. The IRS treats a single-member LLC as a “disregarded entity” by default, which means it is taxed like a sole proprietorship, with profit reported on Schedule C of your personal return. Members also pay self-employment tax on their earnings, as the SBA points out.

The tax picture can change if the LLC elects to be taxed as an S corporation. Some owners with higher, steady profits may then lower their self-employment tax by paying themselves a reasonable salary. That election adds payroll and filing costs, so get advice from an accountant before choosing it.

Example
Nadia earns $40,000 a year from bookkeeping as a sole proprietor. Forming a single-member LLC would not change her federal tax by itself, since it is taxed the same way by default. She forms one anyway for liability protection, and plans to review an S corporation election with her accountant if her profits grow.

What does each structure cost?

A sole proprietorship has no formation fee, though you may pay for a DBA, a local business license and permits. An LLC adds a state filing fee and, in some states, annual fees or taxes. These vary a lot by state. For example, California charges an $800 annual LLC tax, while Ohio has no annual LLC report. Our guides to starting a business in California and Ohio show the details.

Which should you choose?

A sole proprietorship may suit you if

Your business is low risk, such as writing, tutoring or design.
You are testing an idea and earning small amounts.
Your state’s LLC fees would take a large share of your profit.

An LLC may suit you if

Your work carries a real risk of injury, property damage or large claims.
You have significant personal assets to protect.
You plan to hire staff, sign leases or take on partners.
Clients or lenders expect a formal entity.

Example
Jamal runs a handyman business from his van. One mistake on a job could lead to a costly claim. He forms an LLC and buys general liability insurance, because the LLC alone does not cover every risk, especially claims from his own work.

Insurance matters in both cases. An LLC does not protect you from claims caused by your own negligence in every situation, so liability insurance is still wise.

Frequently asked questions

Is an LLC better than a sole proprietorship?

Not always. An LLC adds liability protection but costs more and needs more paperwork. Low-risk, small businesses often start as sole proprietors.

Does an LLC save on taxes?

Not by default. A single-member LLC is taxed like a sole proprietorship unless it elects corporate tax treatment.

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

Yes. Many owners form an LLC once their business grows. You will need to update your bank account, contracts and licenses.

Does a sole proprietor need an EIN?

Not always, but you need one if you hire employees, and many owners get one to avoid sharing their Social Security number.

Do LLC members pay self-employment tax?

By default, yes. Members are treated as self-employed for their share of earnings.

Does an LLC protect me from everything?

No. Protection has limits, and it can be lost if you mix personal and business funds. Insurance is still important.

Final Thoughts

A sole proprietorship is simple and cheap, but you carry all the risk personally.
An LLC generally protects your personal assets but adds costs and paperwork.
Taxes are the same by default, and both pay self-employment tax.
Base your choice on your risk, your assets and your state’s fees.
