Best LLC for freelancers: S-corp breakeven and classification

Most freelancers form an LLC about a year later than they should and elect S-corp status about two years earlier than they should. Both mistakes come from the same place: reading advice written for a different revenue level than the one you are at.

Sole proprietor until when, exactly

You are already a business. Invoice one client as yourself and you are a sole proprietor by default — no filing, no fee, and your personal assets and the business's are the same pool. The question is not whether to be a business but when the separation starts being worth its annual cost.

Four triggers, any one of which is enough:

• A client's procurement process requires an entity. Extremely common above a certain client size, and it arrives as a deadline rather than a discussion.
• The work can cause real loss. Code that touches payments, advice that moves money, anything with a deadline that costs someone else money if missed. An LLC plus professional indemnity cover is the pairing here — the entity alone is not enough.
• You are hiring. A subcontractor introduces someone else's mistakes into your liability.
• Payment processors and platforms. Some pay entities more readily than individuals, and an entity separates business banking from personal.

What is *not* a trigger: tax. An LLC does not reduce your tax bill. A single-member LLC is disregarded — the same profit lands on the same Schedule C, taxed the same way. Anyone selling you an LLC as a tax strategy is selling you the wrapper and calling it the contents.

Where the S-corp election starts paying

This is the real money, and it is worth being precise. As a sole proprietor or disregarded LLC you pay self-employment tax on your net earnings: for 2026, 15.3% in total — 12.4% Social Security up to $184,500 of earnings and 2.9% Medicare with no cap — applied to 92.35% of net earnings. An additional 0.9% Medicare surcharge applies above $200,000 for a single filer.

Elect S-corp status and the profit splits in two: a reasonable salary, which bears employment taxes, and a distribution, which does not. The saving is 15.3% of whatever sits in the distribution — and the cost is payroll, a second tax return, and a standard of proof for the salary.

Two further points that rarely make it into the comparison. The election also reduces the earnings on which your future Social Security benefit is calculated — a real cost, just a distant one. And the 20% qualified business income deduction under Section 199A, made permanent by P.L. 119-21, applies either way, which narrows the gap between the two structures more than most calculators admit.

Classification: the risk that points at your client

If you work full-time hours for one client, on their schedule, with their equipment, under their direction, you may be an employee in fact regardless of what the contract says. The exposure mostly sits with the client — back payroll taxes, penalties, sometimes benefits — which is precisely why large clients care so much about it, and why some of them will insist you have an entity, insurance and other clients before they will engage you.

For you, the practical consequences are smaller but real: a single-client freelancer looks fragile to a lender, to a mortgage underwriter, and to anyone valuing the business. Diversifying clients is a structural improvement, not just a commercial one.

If you are not a US person: the question that actually matters

A non-resident freelancer with a US LLC has one question worth answering carefully, and it is not which state to file in. It is whether the income is effectively connected with a US trade or business.

The distinction is about where the work is performed and by whom, not about where the client is or where the LLC is registered. A developer sitting in Lisbon writing code for a New York client is performing services in Portugal. That is the starting point of the analysis — but it is a starting point, and it moves if there are people, an office, or dependent agents in the United States.

• The S-corp election is unavailable to you. Section 1361 bars non-resident alien shareholders. This is not a planning point; it is a closed door.
• A single-member LLC is disregarded, and owes Form 5472 with a pro-forma Form 1120 every year, at a $25,000 penalty for failure to file — regardless of whether any tax is due.
• Filing nothing because you concluded there is no tax is the most expensive available option. The penalty attaches to the missing form, not to the missing payment.
• Your home country still exists. Its CFC and personal residence rules may tax the same profit, and a US LLC does very little to prevent that.

Which state

Your home state if you live in the United States. Freelancing is performed where you are, so a Wyoming LLC operated from Illinois is an Illinois business with an extra annual report. If you are outside the US with no US presence, Wyoming and New Mexico are sensible defaults on cost and privacy grounds.
