Here's the short version: a sole proprietorship costs nothing to start and gives you no liability protection; an LLC costs an average of $220 in Year 1 in state fees and separates your personal assets from your business debts. By default, both are taxed exactly the same way. So the LLC vs sole proprietorship decision is really one question — how much is the liability shield worth to you, given what your business actually does? This guide compares both structures on cost, liability, taxes and credibility, with 2026 numbers.

LLC vs sole proprietorship at a glance
| Factor | Sole proprietorship | LLC |
| How it starts | Automatically, the moment you do business as yourself | File Articles of Organization with your state |
| State cost, Year 1 | $0 state formation fee | $50–$1,000 by state (average $220) |
| Annual state cost | $0 | $0–$810/yr by state |
| Liability protection | None — you and the business are the same legal person | Yes — business debts generally stay with the business |
| Default federal taxes | Pass-through: profit taxed on your personal return + 15.3% self-employment tax | Identical for a single-member LLC |
| S-Corp tax election | Not available | Available once profit justifies it |
| Business name | Your own name, or a DBA registration for a trade name | Name is registered and protected statewide |
| Paperwork | Minimal | Operating agreement + annual reports in most states |
What does each structure cost in 2026?
A sole proprietorship has no state formation step at all — you may still need a local business license or a DBA ("doing business as") registration to use a trade name or open a bank account, and those small local costs apply to LLCs in many places too. An LLC's state fees are the real difference: an average of $220 in Year 1 (median $160), ranging from $50 total in no-annual-fee states like Arizona, New Mexico, Mississippi and Missouri, up to $880 in California and $1,000 in Massachusetts. Then most states charge a recurring report fee — $0 in the no-fee states, $15/yr in Kentucky, $400/yr in Delaware, $810/yr in California.
Over five years, an LLC costs between $50 and $4,120 in state fees depending on where you form; a sole proprietorship costs $0. Check your exact state in the LLC cost calculator or browse the cost by state index — in a cheap state, five years of protection can cost less than one month of business insurance.
How much liability protection does an LLC actually give you?
This is the entire reason LLCs exist. As a sole proprietor, there is no legal line between you and your business: if the business is sued or can't pay its debts, your personal savings, car and — in many cases — your house are on the table. An LLC draws that line. If the business is sued or defaults, creditors can generally reach only business assets, not your personal ones.
The shield has honest limits, and a good guide should name them. It does not protect you from your own negligence or wrongdoing (if you personally injure someone while working, you're personally liable either way). It does not stop a bank from asking you to personally guarantee a loan — most new businesses sign guarantees, which contract around the shield for that debt. And it can be weakened if you treat the business as your personal wallet: mixing funds, skipping the separate bank account, and ignoring formalities gives a court reasons to "pierce the veil". The protections are real for the common cases founders worry about — a client dispute, a contract gone wrong, business debt in a bad year — provided you keep finances separate from day one (see our guide to opening a business bank account).
Are LLC taxes different from sole proprietorship taxes?
By default, no — and this surprises people. A single-member LLC is a "disregarded entity": the IRS ignores it, and your profit lands on your personal return exactly like a sole proprietor's, including the same 15.3% self-employment tax on top of income tax. Multi-member LLCs file as partnerships, the multi-owner equivalent. Forming an LLC purely "for the tax savings" saves nothing on its own.
The difference is an option only the LLC has: it can elect to be taxed as an S-Corp, splitting your income between a salary and distributions that skip self-employment tax. That starts paying off at roughly $40,000–$60,000+ of annual profit, after payroll and accounting costs — the full math is in our LLC vs S-Corp guide. A sole proprietorship can never make that election; you'd have to form an entity first. Either way, once formed you'll want an EIN — free from the IRS — instead of handing out your Social Security number.

- You're testing an idea with little or no revenue and no real risk exposure — you can always form the LLC later (see the FAQ).
- Your work carries minimal liability: no employees, no premises, no client contracts with teeth, nothing that can injure anyone or rack up business debt.
- Simplicity is the priority and income is a small side stream you report alongside a job.
When should you form the LLC?
- You sign contracts, take on business debt, or work on client sites/premises — the situations where something can actually go wrong.
- The business is becoming your real income — the fee (as low as $50 in several states; check the best states ranking) is trivial next to what's now at risk.
- You want the S-Corp option open as profits approach the $40,000–$60,000 range.
- Credibility matters: "Acme Design LLC" on a contract and invoice reads differently from a personal name, and your registered name is protected from copycats within your state.
- You're hiring or taking on a co-owner — both are cleaner inside an entity with an operating agreement, per our 7-step guide to starting an LLC.
Frequently asked questions
Can I start as a sole proprietor and switch to an LLC later?
Yes — founders do it all the time. You file the Articles of Organization when you're ready, get an EIN, open an LLC bank account and move contracts and assets into the business. Nothing about starting as a sole proprietor locks you in; just know the liability shield only covers what happens after the LLC exists.
Does an LLC save taxes compared to a sole proprietorship?
Not by itself — default taxation is identical, including the 15.3% self-employment tax. Savings only appear if your LLC elects S-Corp status and your profit is high enough (roughly $40,000–$60,000+) for the savings to beat the added payroll and accounting costs.
Do I need an LLC to open a business bank account?
No. Sole proprietors can open business accounts too, usually with a DBA certificate if the account uses a trade name. But keeping business money separate is far easier — and far more convincing — with an LLC and its own business bank account.
Is a sole proprietorship really free?
At the state level, yes — there's no formation filing at all. Local business licenses, permits or a DBA registration may still apply depending on your city and industry, and those same local costs typically apply to LLCs too. The LLC's extra cost is purely the state fees shown in the calculator.
