LLC vs Sole Proprietor: Which One Saves You More in Taxes

Search for whether an LLC saves you tax and you will find a hundred pages implying it does, most of them written by companies that charge a few hundred dollars to file the paperwork. The honest answer is duller and more useful: for the overwhelming majority of one-person businesses, forming an LLC changes the federal tax bill by exactly nothing.

That is not a reason to skip the LLC. It is a reason to stop shopping for one on tax grounds and start evaluating it on the grounds where it actually earns its keep. Here is the math, run both ways, with the costs included.

The answer is neither, and that is not a dodge

"LLC" and "sole proprietor" are answers to two different questions. Sole proprietorship is a tax classification: it describes how the IRS treats your income. An LLC is a state-law entity: it describes who owns the business and who can be sued when something goes wrong. Those categories overlap, which is why the comparison gets muddled, but they are not alternatives to one another.

A one-person LLC in its default state is still taxed as a sole proprietorship. You can have both at once, and most freelancers who form an LLC do. The question worth asking is not which one saves more. It is what each one is for.

A single-member LLC is invisible on your federal return

The IRS calls a one-owner LLC a disregarded entity. The phrasing is unusually literal. Unless you file an election to be treated otherwise, the agency looks straight through the LLC to you, and the business income lands on Schedule C of your personal Form 1040 exactly as it would have without the entity. Net profit flows to Schedule SE, self-employment tax gets calculated at 15.3% on 92.35% of that profit, and the same brackets apply to the same taxable income.

So the effect of forming a single-member LLC on your federal tax is $0. Not "modest." Not "depends." The two returns are the same document with a different business name on line C.

Where this myth comes from is understandable. People conflate the LLC with the S-corp election, which does change the math, and which is usually made through an LLC. Owning the entity is a prerequisite for the strategy, so the entity gets credit for the savings. The LLC vs sole proprietor comparison page lays out that sequence in more detail, and the calculator there will show you the same total either way.

Two things in that example are worth flagging. First, self-employment tax is the larger of the two numbers, and it is the one the entity choice cannot touch. Second, the qualified business income deduction is available to both, because it follows the income rather than the entity. If those mechanics are new, the self-employment tax explainer walks through why the 15.3% headline overstates the real cost.

What an LLC actually buys, and what it costs

The case for an LLC is real, it is just not a tax case. Three things it does buy:

A liability shield. If a client sues over work product, or a contractor you hired injures someone, the LLC is the party on the hook and your personal savings sit behind a legal wall. That wall has limits (it will not protect you from your own professional negligence, and courts will pierce it if you commingle funds), but it exists, and a sole proprietorship offers none of it.

A name you can put on a contract. Some clients, particularly larger ones, will only onboard vendors that are registered entities. Others simply take a registered business more seriously in a rate negotiation.

Cleaner books, enforced. The LLC needs its own bank account to keep the shield intact, and that requirement pushes people into the separation that makes April survivable.

Against that sits an annual bill that arrives whether or not the business makes money. Formation runs from about $50 to $500 depending on the state, registered agent services cost $100 to $300 a year if you use one, and a handful of states charge a recurring tax on the entity itself. California is the harshest: $800 every year under Revenue and Taxation Code Section 17941, plus a gross-receipts fee that starts at $900 once California-source income reaches $250,000.

Priya may still be right to form it. A copywriter who signs indemnification clauses has a real exposure problem, and $685 is cheap insurance against it. The point is that she should decide that on those terms, and not while under the impression that the entity is paying for itself. The side-by-side comparison tool will show her the same federal total under either label.

The S-corp election is the thing people are actually asking about

When someone insists an LLC cut their tax bill, they almost always mean they filed Form 2553 and elected to have the LLC taxed as an S corporation. That election changes the structure of the income. Instead of one pot of self-employment income, you split the profit into a W-2 salary you pay yourself (subject to payroll tax) and a distribution (not subject to payroll tax).

The salary has to be reasonable for the work performed, which is an IRS facts-and-circumstances test rather than a percentage rule, and paying yourself too little invites the agency to recharacterize the distributions. Within that constraint, the portion above your salary escapes the 15.3%.

Where the $1,938 goes

Take Marcus's same $95,000 and elect S-corp treatment with a $60,000 salary. Payroll tax on the salary runs $9,180 (both halves combined). The remaining $30,410 flows through on a K-1 with no payroll tax attached. Income tax rises to $9,722, partly because W-2 wages are not qualified business income, so his QBI deduction shrinks from $14,438 to $6,082. Total federal cost: $18,902, a gross saving of $1,938.

Then subtract what the structure costs to run. A payroll service is $500 to $1,000 a year, an 1120-S return adds $800 to $1,500 to your tax prep, and some states impose an entity-level tax on top. At $95,000 of profit the saving and the overhead are close enough that the honest verdict is "roughly a wash, with more paperwork." That gap widens as profit climbs, which is why the election tends to make sense somewhere north of $80,000 and becomes clearly worthwhile well above six figures. The five situations where it backfires are covered separately in when an S-corp election is the wrong move.

Three setups, one business

Read that table left to right and the sequence is clear. The LLC column is a legal upgrade at a modest price. The S-corp column is a tax strategy with real administrative weight, and it sits on top of the LLC rather than replacing it.

What to do with this before Dec. 31

If you are early and profit is modest, stay a sole proprietor and put the $685 toward a business bank account and a bookkeeping habit. Neither costs much, and both do more for your April than an entity will. Readers in their first year of freelancing almost always get more from the habits than the paperwork.

If your work carries real liability, sign contracts with indemnification clauses or subcontract to other people, form the LLC now and treat the annual fee as insurance. Budget it as a cost, not an investment, because your federal tax will not move. The LLC vs sole proprietor page has the calculator alongside a section on state-level LLC costs.

If profit has cleared $80,000 for two consecutive years and looks stable, that is the point to price out the S-corp election with someone who can see your whole return, including state treatment. The election has a 75-day filing window and a five-year lockout if you revoke it, so it rewards deliberation more than speed.

And if you take one thing from all of this, take the reason the entity choice cannot solve the problem people want it to solve. Self-employment tax attaches to the income, not to the wrapper around it. Change the wrapper and the tax follows you into it. Change how the income is classified, as the S-corp election does, and the number finally moves.
