LLC vs Sole Proprietorship: Which Should a New Founder Choose?

If you're starting a business in 2026, the LLC-vs-sole-prop question comes up roughly 10 minutes after the idea does. Here's the honest answer most CPAs won't give you in one paragraph.

The 30-second answer

• Just testing an idea, no revenue yet, low liability: sole proprietorship is fine.
• Charging clients, signing contracts, or selling physical products: form an LLC. Today.
• Already over $40k/year and want to lower self-employment tax: look at an S-Corp election on top of the LLC.

That covers 95% of new founders. The rest of this article is the why.

What a sole proprietorship actually is

A sole proprietorship is what you are by default the moment you do business in your own name. There is no paperwork, no fee, and no separation between "you" and "the business."

Pros:

• $0 to start.
• Taxes filed on your personal return (Schedule C).
• Maximum simplicity.

Cons:

• You are personally liable for every debt, lawsuit, and chargeback. If your side business gets sued, your house is on the table.
• Banks won't open business accounts in the business name.
• Looks unprofessional on contracts.

What an LLC actually gives you

An LLC ("Limited Liability Company") is a legal wrapper that separates you from the business.

Pros:

• Liability shield. If the business gets sued, your personal assets are generally protected — provided you don't co-mingle funds.
• Credibility. Clients, suppliers, and Stripe take you more seriously.
• Flexible taxation. By default it's a "pass-through" like a sole prop, but you can elect S-Corp later.
• Brand protection. Most states reserve the LLC's name in that state.

Cons:

• $50–500 to file depending on state.
• Annual report fees in most states.
• You must keep business and personal money separate.

When sole prop is genuinely fine

• You're freelancing on the side and pulling in <$10k/year.
• You sell zero physical products.
• You don't sign client contracts above a few hundred dollars.
• You're inside a 30-day "is this even real?" test.

When you should form an LLC immediately

• You sell physical products of any kind. (Liability is real.)
• You sign client contracts.
• You collect personal data (email lists count).
• You hire any contractor.
• You want to be able to sell or transfer the business later.

The S-Corp question

Once your business profits more than ~$40k/year, talk to a CPA about electing S-Corp status on top of your LLC. The short version: it can save you several thousand dollars in self-employment tax annually, in exchange for running payroll for yourself.

Don't do this on day one — payroll, additional filings, and CPA fees will eat any savings until you're consistently profitable.

How to actually form an LLC (today)

1. Pick a state. Your home state unless you have a specific reason otherwise. Forget Delaware/Wyoming hype unless you're raising venture capital.
2. Pick a name. Search your Secretary of State's business database first.
3. File Articles of Organization online. ($50–$500.)
4. Get an EIN from IRS.gov. (Free, instant.)
5. Open a business bank account with the EIN and Articles.
6. Draft a one-page Operating Agreement (even single-member).

Total time: under 4 hours. Total cost: under $300 in most states.

What about Inc. / C-Corps?

Skip them unless:

• You're raising priced-round venture capital, or
• You plan to issue stock options.

C-Corps are taxed twice and have far more compliance burden. Most successful 6- and 7-figure founders are LLCs.

The decision tree

Will you ever sign a contract worth >$1,000? -> LLC
Will you ever sell a physical product? -> LLC
Are you collecting customer payments via Stripe/Shopify? -> LLC
Do you have any personal assets worth protecting? -> LLC
Are any of those answers "no"? -> Sole prop is fine, for now

The LLC isn't a fancy upgrade — it's the boring infrastructure that lets you sleep at night while the business grows.
