LLC vs Self-Employed: Real Costs, Liability, and Tax Differences for Small US Businesses

This isn’t legal or tax advice — always confirm specifics with a lawyer or accountant licensed in your state, since LLC costs and rules vary meaningfully by state. But the general shape of this decision is consistent enough across the US to walk through honestly: what each structure actually costs, what it actually protects, and when the switch from one to the other genuinely pays for itself.

What Each One Actually Is

Sole proprietorship: the default status the moment someone starts doing paid work under their own name — no formation paperwork, no separate legal entity. The business and the person are legally the same thing
LLC (Limited Liability Company): a separate legal entity formed with the state, which is what creates a legal line between personal assets and business liabilities. Requires formation paperwork, a filing fee, and in most states, an ongoing annual fee or report

The State-by-State Costs That Change the Math (NY, CA, TX)

The “$50 to $500” range above hides the real story: three states every freelancer asks about land in completely different places, and the state you file in matters more than the national average. This is general information, not legal or tax advice — confirm the current fee on the state’s own site before you file, because fee schedules change.

New York: Articles of Organization cost $200, per the New York Department of State’s own fee schedule. Then comes the part no other state has: within 120 days you must publish notice of formation in two newspapers designated by your county clerk, once a week for six consecutive weeks, and then file a Certificate of Publication with a $50 fee, per the Department’s forming an LLC guide. Newspaper charges are set by the papers, not the state, and vary widely by county — this is why New York is routinely the most expensive state to form in despite a modest $200 filing fee. A $9 biennial statement follows every two years.
California: formation itself is $70, but the number that actually matters is the Franchise Tax Board’s flat $800 annual tax, owed every year regardless of income until the LLC is formally cancelled — the temporary first-year exemption only covered tax years beginning in 2021–2023, so a new LLC today owes the full $800 in year one. Add a $20 Statement of Information, and California is the state where the ongoing cost dwarfs the filing cost.
Texas: the Certificate of Formation (Form 205) costs $300, per the Texas Secretary of State’s Form 205 instructions, and Texas charges no annual report fee to the Secretary of State. The recurring obligation is a franchise tax filing with the Comptroller each May 15 — most small LLCs owe no tax under the no-tax-due threshold, but the filing itself still has to happen.

The honest read: if you’re choosing a state to file in, don’t shop for the cheapest filing fee — shop for the cheapest three-year cost, publication and annual taxes included. New York’s $200 looks cheap until publication lands; California’s $70 looks cheap until the $800-a-year tax lands.

The Real Cost Difference

Sole proprietorship: effectively free to start — no formation filing required. An EIN (Employer Identification Number) from the IRS is free either way and optional at this stage, though useful for opening a business bank account
LLC formation fee: a one-time state filing fee, commonly somewhere between $50 and $500 depending on the state
LLC ongoing costs: most states charge an annual report fee or franchise tax to keep the LLC in good standing — this ranges enormously by state, from near-zero in some states to a flat $800/year minimum in California regardless of income, which is worth checking specifically for the state of formation before assuming the cost is trivial

What Liability Protection Actually Means Here

An LLC’s main practical benefit is separating personal assets (a house, personal savings, a car) from business debts and most lawsuits against the business — if the business is sued or can’t pay a debt, a sole proprietor’s personal assets are generally exposed, while an LLC’s structure is built specifically to prevent that in most circumstances.

The important caveat: an LLC doesn’t protect against a claim of personal negligence or malpractice for someone’s own direct actions — if a freelancer personally causes harm through their own work (not just a business debt), that protection has real limits. An LLC reduces exposure, it doesn’t eliminate it, and a real freelance contract with clear scope and liability terms still matters regardless of which structure is chosen — the LLC and the contract solve different parts of the same risk, not the same part twice.

Taxes: Where It Gets Genuinely More Complex

By default, both a sole proprietorship and a single-member LLC are taxed identically — as “pass-through” income reported on the owner’s personal tax return (Schedule C), with the same self-employment tax obligations either way. Forming an LLC alone doesn’t change tax treatment.

Where it can change is an S-corp election — an LLC can elect to be taxed as an S-corporation, which allows an owner to pay themselves a “reasonable salary” (subject to self-employment tax) and take additional profit as a distribution (not subject to self-employment tax), potentially reducing the total self-employment tax bill. This only makes practical sense once net profit is consistently high enough — commonly discussed around $40,000-$60,000+ in net profit, since below that, the added accounting complexity and payroll requirements of an S-corp election usually cost more than they save.

When Staying a Sole Proprietor Makes Sense

Just starting out, testing whether the work is sustainable before adding formation costs and paperwork to the mix
Low-liability-risk work — writing, most consulting, design work without major legal or physical-safety exposure
Want zero additional paperwork or annual fees while income is still inconsistent or low

When Forming an LLC Makes Sense

Client-facing work with real liability exposure — development work handling sensitive client data, physical products, anything involving signed contracts and real financial stakes for the client
Consistent, meaningful income where the S-corp election’s tax savings genuinely outweigh the added complexity
Client credibility matters — some larger clients and agencies specifically prefer or require working with an LLC or corporation rather than an individual, particularly for larger contracts
Personal asset protection actually matters — someone with significant personal savings, a home, or other assets has more to lose from a lawsuit than someone just starting out with little to protect yet

A Practical Path, Not a Permanent Decision

Starting as a sole proprietor and forming an LLC once revenue becomes consistent and real liability exists is a common, reasonable progression — it’s not a mistake to start simple. The switch itself is a well-worn process (most states have straightforward sole-prop-to-LLC conversion paths), so waiting until the LLC’s benefits clearly outweigh its costs, rather than forming one preemptively “just in case,” is usually the more capital-efficient choice for someone just starting out. Our guide to what to know before registering a business covers the broader registration decision this ties into, including signals (a bank asking for registration, suppliers requiring formal contracts) that suggest the moment has actually arrived.

Where This Fits With Client Structure

Once operating as an LLC with real ongoing client relationships, the way work is structured often shifts too — our agency retainer structure guide covers moving from one-off project invoices to retainers, a transition that tends to happen around the same stage as the LLC decision, since both usually follow from the same underlying signal: consistent, higher-stakes client work rather than occasional gigs.

FAQ

Do I need an LLC before I take my first paying client?

No. A sole proprietorship is the default the moment you start doing paid work under your own name — no formation paperwork, no separate entity. The question is not whether you can start without an LLC, but when the risk and income justify adding one.

What does an LLC actually protect, in plain terms?

It creates a legal line between your personal assets and the business’s liabilities, so a business debt or lawsuit does not automatically reach your house or savings. The post’s caveat matters here: that line is not absolute, and it does not replace insurance or clean business practices.

Does forming an LLC change my taxes?

Not by itself. A single-member LLC is taxed like a sole proprietorship by default — the change people usually mean when they talk about LLC tax savings is a separate S-corp election, which brings its own payroll and compliance costs. Forming the entity and electing the tax treatment are two different decisions.

When is staying a sole proprietor the right call?

When the work is low-risk, you have no employees, and the income does not yet justify filing fees, annual reports, and state franchise taxes — California’s flat $800 a year regardless of income is the post’s sharpest example of a cost that only makes sense once the business can carry it. This post is general information, not legal or tax advice, and state rules vary enough that a local professional is worth a call before you file.
