LLC vs. Sole Proprietorship for Freelancers: Liability, Taxes, and the S-Corp Question

For a freelancer, forming an LLC changes who is liable for the business's debts and lawsuits; it does not change taxes. A single-member LLC is ignored for federal tax by default, so it files the same Schedule C and pays the same 15.3% self-employment tax as the sole proprietorship you already are. Tax savings enter the picture only with a later S-corp election, which adds payroll and filing costs and pays off only above a profit level that depends on those costs. This is education about how the pieces fit, not legal advice: entity law is state law, and a short conversation with a lawyer or accountant in your state is the right last step.

The default: you are a sole proprietor the day you invoice

Nobody forms a sole proprietorship. It is what you are the moment you earn money on your own: legally, you and the business are the same person. Clients send you a 1099, you report the profit on Schedule C of your personal return, you owe income tax on it plus self-employment tax, and you make quarterly estimated payments (the deductions guide covers what comes off that profit first) because nobody withholds for you. The self-employment tax guide covers the 15.3% and why half of it comes back.

The default also means unlimited personal liability. If the business is sued or cannot pay a debt, your savings, your car, and your home are reachable, because there is no line between the business's assets and yours. For a freelancer whose worst case is an unpaid invoice, that risk is small; for one who hires subcontractors, signs a lease, or works in a field where a mistake causes real damage, it is the whole reason the LLC exists.

What an LLC changes: the liability shield, and what keeps it standing

A limited liability company is a legal entity created by a state filing. Once it exists, the business's contracts, debts, and lawsuits belong to the LLC, and in most cases a creditor of the LLC can reach only what the LLC owns. That is the shield, and it has three limits worth knowing before paying for it.

1. It holds only if you treat the LLC as separate. Its own bank account, contracts signed in the LLC's name, invoices from the LLC, and no personal bills paid from the business account. Mix the money and a court can set the shield aside ("piercing the veil"), which is the most common way single-member LLCs lose the protection they paid for.
2. It does not cover your own negligence. If a client is harmed by your professional work, you are personally liable for your own conduct regardless of the entity. That is what professional liability (errors and omissions) insurance is for; the LLC and the policy cover different risks.
3. It does not cover what you personally guarantee. A lender or landlord will usually ask a one-person LLC's owner to sign personally, which puts that debt back on you.

What the shield does cover well: claims arising from the business that are not your personal conduct (a subcontractor's mistake, a fall in the studio, a vendor dispute), and the general separation that keeps a business creditor from reaching personal accounts. Licensed professionals in some states must use a professional LLC (PLLC) variant; the state licensing board will say.

What an LLC does not change: the tax return is identical

By default the IRS treats a single-member LLC as a "disregarded entity": for federal income tax it does not exist, and the owner reports everything exactly as before. Same Schedule C, same net profit, same self-employment tax on 92.35% of it, same quarterly estimates, same deductions. The profit is pass-through income in both cases: taxed once, on your personal return, at your personal rates, and eligible for the qualified business income deduction in both cases. Anyone who says an LLC "saves on taxes" is either describing the S-corp election below or describing nothing.

State tax can differ. A few states charge LLCs an annual franchise tax or a fee tied to revenue that a sole proprietor never pays, and that cost is real money against a shield you may or may not need. It is also the reason the entity decision is a state-specific one.

What an LLC costs: filing, annual fees, and housekeeping

Forming an LLC means a filing fee to the state, in many states an annual report with a fee, in some states a franchise tax, and usually a registered agent (you can be your own in most states if you have an in-state address). None of these figures are stable across states or years, so check your secretary of state's site rather than a blog. Add a separate business bank account, a bookkeeping habit that never mixes money, and an operating agreement (a short document, even for one member, that some banks ask for). The recurring cost of a single-member LLC in a low-fee state is small; in a high-fee state it can be the largest fixed expense a low-earning freelancer has, which is why the decision rule below starts with revenue and risk rather than with the form.

The S-corp election: a tax choice layered on the LLC

An S corporation is not a different entity; it is a tax election an LLC (or corporation) makes with the IRS. After the election the business is still a pass-through, but the owner who works in it must be paid a reasonable salary through payroll, subject to Social Security and Medicare taxes like any employee, and only the profit left after that salary is distributed free of self-employment tax. The saving is the 15.3% not paid on the distribution. The cost is everything a payroll creates: a payroll service, quarterly payroll filings, a W-2 to yourself, a separate business tax return, and in some states an entity-level tax.

Three things keep the saving smaller than it first looks. The salary must be reasonable, meaning what you would pay someone else to do the work, and a token salary with large distributions is the classic audit pattern. Retirement contributions shrink, because the employer share is now a percentage of the W-2 salary rather than of total profit. And the qualified business income deduction is computed on the profit after your salary, so it shrinks too. The election pays only when the self-employment tax saved on distributions clearly exceeds the payroll and filing costs plus those side effects. The profit level where that happens depends on your state and on what payroll and a corporate return cost you, not on a fixed number; an accountant can run it in an hour, and that hour is the right way to decide.

Worked example: $120,000 of profit three ways

Take a developer with $120,000 of net profit after expenses.

• Sole proprietor: self-employment tax is 15.3% of 92.35% of $120,000, about $16,955. Half of it is deductible.
• Single-member LLC, default tax: identical. About $16,955, the same return, plus whatever the state charges the LLC.
• LLC taxed as an S corp: suppose a reasonable salary of $70,000 (illustrative; it depends on the work and the market). Payroll taxes on the salary run 15.3% across both halves, about $10,710, and the remaining $50,000 is distributed with no self-employment tax on it. Gross saving: roughly $6,200 a year.

Now subtract the costs. A payroll service and the separate return might run a few thousand dollars combined, more in some markets; some states add an entity tax; the employer retirement share falls from about 20% of roughly $111,500 (net earnings after the half of SE tax) to 25% of the $70,000 salary, which is a smaller number; and the QBI base drops from most of the $120,000 to the $50,000 distribution. Net of all that, the developer might keep $3,000 to $4,000 of the $6,200, or less. At $60,000 of profit the same exercise usually comes out near zero or negative, which is why nobody with a new freelance business should start here. The self-employment tax calculator gives the first line on your own profit; the rest is an accountant's spreadsheet.

Sole proprietorship vs LLC vs LLC taxed as S corp: the comparison

The EIN and the business bank account: do these regardless

Two steps improve every column of that table and cost almost nothing. An Employer Identification Number is free from the IRS, takes minutes to get online, and lets you put a business number on the W-9 forms clients request instead of your Social Security number. A sole proprietor can operate without one, but an LLC will need it to open a bank account, and every freelancer benefits from keeping their SSN off a dozen client vendor files. The separate business account is the second step, and it is not optional for an LLC: the shield depends on it, and even for a sole proprietor it turns Schedule C from a reconstruction into a report. Client payments in, the tax set-aside and your own salary out, nothing personal in between.

The decision rule

1. Just started, small revenue, low-risk work: stay a sole proprietor, get the EIN, open the business account, pay the quarterlies. Revisit at the end of the first full year.
2. Signing contracts with real penalties, hiring subcontractors, leasing space, or working where a mistake can cause damage: form the LLC, keep it separate, and carry professional liability insurance for the part the LLC cannot cover.
3. Profit has grown to the point where a payroll service would be a rounding error: have an accountant run the S-corp comparison on your actual numbers, including the retirement and QBI side effects and your state's costs. Elect it only if the net saving is clear and the reasonable salary is one you can defend.
4. Whatever you choose, revisit yearly, because the fees, the profit, and the law all move. State LLC fees change, the federal rules for pass-through income change, and the point where the S corp pays shifts with them.

Nothing above replaces a lawyer for the liability question or an accountant for the election; it is the map that makes those conversations short. The rest of the self-employed toolkit, from the rate to the retirement plan, lives in the freelancer money collection.

Whichever entity you pick, the discipline underneath is the same: business money and personal money never touch. Stoia keeps the business account, the tax set-aside, and the household budget in one live budget, launching 2026, so the separation the shield depends on is visible every day.
