Should a US freelancer form an LLC or stay a sole proprietor?

Stay sole prop while earning under $50K net/year. Above $50K, an LLC adds personal liability protection (separating your personal assets from business risk) for $200–800/year in formation and annual fees. The LLC doesn't change your taxes (you're still taxed as sole prop unless you elect S-Corp), but it does protect your house and savings if a client ever sues. Most freelancers form an LLC the moment a client contract requires it or when net income clears $50K, both reasonable triggers.

When should a freelancer elect S-Corp status?

Elect S-Corp status when net income clears $100K/year and stays there. Below $100K, the annual S-Corp compliance costs ($1,500–3,500/year for payroll, separate tax return, bookkeeping) usually exceed the SE-tax savings. At $150K net, S-Corp typically saves $3–7K/year after compliance costs. At $200K+, S-Corp clearly wins for most freelance professions. The most expensive mistake isn't staying sole prop too long, it's electing S-Corp at $60K when you'll lose money on overhead. Always run the math with a CPA before electing.

What's the difference between an LLC taxed as a disregarded entity and one taxed as an S-Corp?

An LLC taxed as 'disregarded entity' is the default, the LLC exists for liability protection but the IRS treats your business income identically to a sole prop (Schedule C, all profit subject to self-employment tax). An LLC that elects S-Corp status (Form 2553) is taxed differently: you pay yourself a 'reasonable salary' subject to payroll tax, and remaining profit flows through as a distribution that escapes SE tax. The S-Corp election is what actually saves money, the LLC structure alone provides liability protection but no tax benefit.

How much does it cost to form and maintain an LLC for a freelancer?

Formation cost: $50–500 depending on state (Delaware $90, California $70 + $800 annual franchise tax, New York ~$200, Texas $300). Annual maintenance cost: $0–800/year depending on state. Add a registered agent service ($100–300/year) if you don't want your home address on public record. The cheapest states to form in (Wyoming, New Mexico, Delaware) are popular but you usually have to register as a 'foreign LLC' in your home state too, wiping out the savings. Form in your state of residence unless you have a real reason not to.

Can I switch from sole prop to LLC to S-Corp as my freelance income grows?

Yes, and most successful freelancers do exactly that progression. Sole prop years 1–2 while you're under $50K. LLC formation when income clears $50K or a contract requires it. S-Corp election when net income clears $100K and you have steady months ahead. Each transition is administrative work (1–2 days), not legal complexity. The biggest mistake is locking into a structure too early, pay the right CPA $300 to confirm your structure annually as income grows, and switch when the math justifies it.

LLC vs Sole Prop vs S-Corp for Freelancers: Which Structure Saves You the Most in 2026?

Every US freelancer eventually has to answer: do I stay a sole proprietor, form an LLC, or elect S-Corp status? Most do nothing for years, default to sole prop, and quietly overpay taxes. Others rush into an S-Corp too early and take on $2K+ in annual overhead for tax savings they haven’t earned yet. Here’s the honest decision framework, by income level.

This guide is written for US-based freelancers. (For LATAM-based freelancers, see the Spanish companion covering Mexico, Spain, Argentina, and Colombia structures.) The specifics vary by country, but the core framework applies, pick the structure that matches your income level, not the one that sounds most sophisticated.

Important caveat: nothing in this article is tax or legal advice. Consult a CPA before making a decision. This article is a framework for knowing which questions to ask them.

The three structures, compared

Sole Proprietorship

What it is: you, doing business as yourself. No legal entity. Your Social Security Number is your business ID.

Setup cost: $0.

Annual overhead: $0 (beyond normal tax prep).

Taxes: all income flows to your personal tax return via Schedule C. You pay income tax + 15.3% self-employment tax on net earnings.

Liability protection: none. Your personal assets (home, savings) are at risk if something goes wrong in the business.

Best for: freelancers earning under $50K/year, or in their first 12 months of freelancing.

LLC (Limited Liability Company)

What it is: a legal entity separate from you. You own it, but it’s its own thing in the eyes of the law.

Setup cost: $50–500 depending on state, plus a registered agent (~$100/year).

Annual overhead: $200–800/year depending on state (filing fees, franchise taxes).

Taxes: by default, taxed as a sole proprietorship (a “pass-through” entity). Same Schedule C treatment, same 15.3% SE tax.

Liability protection: separates your personal assets from business liabilities. If you get sued professionally, generally only business assets are at risk.

Best for: freelancers with any meaningful liability exposure, working with larger clients, or earning above $50–60K/year.

S-Corp (technically an LLC with S-Corp tax election)

What it is: not a separate entity, it’s an election you make with the IRS for your existing LLC (or a C-corp, which freelancers almost never use) to be taxed as an S-Corp.

Setup cost: form the LLC (as above) + S-Corp election filing ($0 if done yourself, $500–1,500 if a CPA does it).

Annual overhead: $1,500–3,500/year. You’re required to run payroll for yourself, file a separate business tax return (Form 1120-S), and typically need a bookkeeper and CPA.

Taxes: you split income into “salary” (subject to payroll tax, ~15.3%) and “distributions” (not subject to SE tax). This is where the savings come from.

Liability protection: same as LLC.

Best for: freelancers earning net profit above $60–100K/year (depending on state and other factors) who plan to stay at that income level.

The biggest structural mistake freelancers make isn’t staying sole prop too long, it’s S-Corp’ing too early. If the annual overhead ($1.5–3.5K) exceeds the tax savings, you’ve made yourself poorer while feeling more “legitimate.”

The decision framework

Business strategy planning — Good strategy turns scattered effort into compounding results.

If you’re earning under $50K/year (net profit, after expenses):

Stay a sole proprietor.

Why: the liability risk is usually low. The LLC overhead ($200–800/year) buys you protection, but at this income level, you haven’t yet generated enough to make the protection worth the fees for most freelancers.

Exceptions:

You work with enterprise clients who require an LLC
Your work has real liability risk (legal advisory, medical, financial)
You have significant personal assets to protect (home equity, savings)

In any of those cases, form an LLC even at lower income levels.

If you’re earning $50K–100K/year:

Form an LLC, taxed as a disregarded entity (default sole-prop taxation).

Why: you have enough income that a liability event would actually matter. The LLC protection is cheap insurance. But you’re not yet at the threshold where S-Corp savings outweigh the overhead.

This is where most senior freelancers live. LLC with sole-prop taxation: protected, simple, low overhead.

If you’re earning $100K+/year (net profit):

Consider the S-Corp election with your CPA.

The math: S-Corp savings come from splitting income into salary vs distributions. Distributions aren’t subject to the 15.3% SE tax.

Example:

Net profit: $150K
Reasonable salary: $75K (must be “reasonable”, IRS requires this)
Distributions: $75K

SE tax on sole prop: $150K × 15.3% = ~$20K (after adjustments) SE equivalent on S-Corp: only on $75K salary = ~$10K

Potential savings: ~$10K/year.

Subtract costs:

Payroll service: $500–1,200/year
Business tax return (Form 1120-S): $800–1,500
State franchise fees and compliance: $200–800
Bookkeeping (often needed): $1,200–2,400

Net benefit: $3K–7K/year at $150K income level.

At $100K income, the math is tighter. At $200K+, S-Corp clearly wins.

If you’re earning $200K+/year:

Almost certainly S-Corp. The math is too strong to ignore.

At this level, also consider: solo 401(k) or SEP-IRA (tax-advantaged retirement), defined benefit plan (if older), and whether a multi-member LLC (with a spouse) or partnership structure makes sense.

Non-tax reasons to form an LLC earlier

Income isn’t the only factor. LLC makes sense regardless of income if:

Liability risk is real. If a mistake in your work could cost a client real money (legal, medical, financial, data-related work), LLC protection is critical regardless of income.
Contracts require it. Many enterprise clients won’t sign contracts with a sole proprietor. An LLC is required for the relationship.
You have personal assets to protect. Home equity, significant savings, a spouse’s assets, LLC shields these from professional liability.
You’re partnering with someone. Partnerships without an LLC structure create personal liability for each partner’s decisions. LLC is basically mandatory for any multi-person business.

Non-tax reasons to delay S-Corp

Just because the income math works doesn’t mean S-Corp is right. Reasons to delay:

Income volatility. If your income swings from $80K one year to $140K the next, the S-Corp overhead is fixed while the savings aren’t. Let income stabilize before electing.
You’re planning to close or pivot. Winding down an S-Corp has its own costs. Don’t elect if there’s a meaningful chance you’ll stop freelancing or go back to W-2 employment soon.
You can’t commit to compliance. S-Corps have specific payroll, distribution, and filing requirements. If you’d skip these, the IRS can disallow the election. Only elect if you’ll run it correctly.

How to actually set this up

Forming an LLC

Pick your state. Usually your home state. Don’t waste time with “form in Delaware” advice, it applies to venture-backed startups, not solo freelancers.
File articles of organization. On your state’s Secretary of State website. Fees range $50–500.
Get an EIN (Employer Identification Number) from the IRS. Free, 5-minute online form.
Open a business bank account. Required for clean liability separation. See your first business bank account.
Update contracts and invoicing to use the LLC’s name going forward.

Timeline: 1–2 weeks, DIY. Or hire a CPA/lawyer for $300–800 to handle all of it.

Electing S-Corp

Form an LLC first (if you haven’t already).
File IRS Form 2553 to elect S-Corp taxation. Free, but get a CPA’s review before filing, the timing matters.
Set up payroll for yourself. Gusto, Rippling, or ADP. ~$500–1,200/year.
Determine “reasonable salary.” The IRS requires this be defensible, usually 40–60% of net profit, depending on role and industry. Your CPA can help set this.
Make distributions in addition to salary. These aren’t subject to SE tax.
File Form 1120-S annually. Separate from your personal return. Usually handled by your CPA.

Timeline: 2–4 weeks to fully set up. Costs $1,000–2,500 in year 1, $1,500–3,500/year ongoing.

The moves that cost freelancers money

Mistake 1: Staying sole prop way past $100K.

At $150K net, you’re probably leaving $5–10K/year on the table. Over 10 years that’s $50–100K of tax savings foregone.

Mistake 2: Electing S-Corp at $60K.

Overhead eats the savings. You’re paying more to feel more “official.” The business isn’t helped.

Mistake 3: Forming an LLC in Delaware when you live elsewhere.

Now you pay Delaware fees + your home state’s “foreign entity” fees. Double overhead, no benefit.

Mistake 4: Not actually running the S-Corp correctly.

Skipping payroll, paying yourself only through distributions, missing filings. The IRS can revoke the election and assess back taxes. Correct compliance is not optional.

Mistake 5: Thinking “LLC = magic protection.”

LLC protection only works if you keep clean separation. Commingling personal and business funds, skipping formalities, or acting as if the LLC is just an extension of you can pierce the corporate veil. Treat it like a separate entity.

What to ask a CPA

If you’re hiring a CPA to advise on structure (recommended at any income above $50K), ask:

Given my income and expenses, what’s your recommendation for entity structure?
What would the tax math look like if I stayed sole prop vs LLC vs S-Corp next year?
What would a “reasonable salary” look like for my role if I went S-Corp?
What ongoing compliance would I need to handle vs what you’d handle?
What’s your annual cost for this level of service?

A good CPA answers these clearly and gives you specific numbers. A bad one talks in generalities or immediately pushes you toward the most expensive structure. Interview 2–3 before picking.

The pragmatic recommendation

If you’re starting: sole proprietor is fine for 6–18 months. Don’t overthink it.

When your annual net profit crosses $50–60K: form an LLC. One weekend of setup. Protects you.

When your annual net profit crosses $100K and looks stable: consult a CPA about S-Corp election. Usually pays for itself at $125K+.

That’s the whole framework. Most freelancers overcomplicate this or ignore it entirely. The right answer is almost always: match structure to income, in stages, without rushing.
