Entity profile

Sole Proprietorship

Formation cost: $0 — No state filing required for the default form. A DBA ("doing business as") may add $10–$100 at the county clerk if you operate under a trade name.
Tax treatment: Owner reports all business income on Schedule C (Form 1040). Self-employment tax (15.3%) applies to net profit. No separate business return.
Tax form(s): Schedule C (Form 1040)
Liability shield: No — No liability separation — the owner and the business are legally the same person. Personal assets (home, car, savings) are fully exposed to business debts and lawsuits.
Ongoing compliance: None — No annual reports, no registered agent, no separate business bank account required (though recommended). Zero ongoing state compliance.
Best for: Side projects, low-risk freelancing, early-stage experimentation before committing to a formal entity. Appropriate when revenue is modest and lawsuit exposure is minimal.
Key differentiator: Zero cost and zero compliance overhead. The default legal status of any individual doing business — no filing needed. The right starting point for most people testing a business idea.
Verdict: Best for: starting fast, low-risk ventures, and anyone not yet earning enough to justify entity overhead

LLC (Limited Liability Company)

Formation cost: $50–$500 — State-dependent: Wyoming ($100), Delaware ($90 + $300/yr franchise tax), Florida ($125), Texas ($300), Nevada ($425). Cost varies by state; choose formation state carefully.
Tax treatment: Pass-through taxation by default — single-member LLCs file Schedule C (same as sole prop); multi-member LLCs file Form 1065. LLC owners still owe self-employment tax on net profit unless electing S-Corp status.
Tax form(s): Schedule C (single-member) or Form 1065 (multi-member)
Liability shield: Yes — Strong liability shield per each state's LLC act. Business debts and lawsuits generally cannot reach the owner's personal assets — provided the LLC is properly maintained (separate bank account, no commingling).
Ongoing compliance: Low — Light ongoing compliance: annual report ($0–$300 depending on state) plus a registered agent (~$39–$125/yr). No board meetings, no bylaws, no annual minutes required.
Best for: Most small-business operators, real-estate investors, freelancers and consultants who need liability separation without heavy compliance. The best default choice for the majority of new businesses.
Key differentiator: The liability shield without corporate complexity. One filing, minimal ongoing requirements, and flexible profit distribution. Also the foundation for an S-Corp election once income crosses ~$80K/year net.
Verdict: Best for: most small businesses — the right default entity for liability protection without administrative burden

S-Corp (S-Corporation Election)

Formation cost: LLC or corp formation cost + IRS Form 2553 (free) — S-Corp is a tax election, not a separate entity type. You form an LLC or corporation first (state filing cost applies), then file IRS Form 2553 to elect S-Corp tax treatment. Must elect within 75 days of formation or by March 15 of the tax year.
Tax treatment: Pass-through taxation like an LLC, but owner-operators must pay themselves a "reasonable compensation" W-2 salary. Only salary is subject to FICA payroll taxes (15.3%); additional profit distributions are not — creating SE tax savings at higher income levels (~$80K+ net).
Tax form(s): Form 1120-S (corporate return) + Schedule K-1 (per shareholder) + W-2 (owner salary)
Liability shield: Yes — Inherits the liability shield from the underlying LLC or corporation. Strong protection from business debts and lawsuits — same as a standard LLC.
Ongoing compliance: Medium — Requires W-2 payroll for the owner-operator, quarterly estimated taxes, a Form 1120-S annual return, and Schedule K-1 distributions. More compliance than an LLC but less than a C-Corp.
Best for: Profitable single-operator businesses generating ~$80K+ in net income per year. The self-employment tax savings can be significant: at $120K net, an S-Corp election can save $5,000–$10,000/year depending on reasonable compensation benchmarks.
Key differentiator: The SE-tax savings play. By splitting owner income into salary (subject to FICA) and distributions (not subject to FICA), an S-Corp election reduces the 15.3% self-employment tax burden once income is high enough to justify payroll overhead.
Verdict: Best for: solo/small business owners above ~$80K/year net who want to reduce self-employment tax; requires payroll

C-Corp (C-Corporation)

Formation cost: $100–$1,000 — State-dependent: Delaware ($90 + $400/yr franchise tax minimum) is the standard for VC-backed companies. Wyoming, Nevada, and Texas are cheaper but less preferred by investors. Filing fees vary by state.
Tax treatment: Double taxation: the corporation pays 21% federal corporate income tax on net profit, then shareholders pay income tax again on dividends received. This double tax is the primary reason most small businesses avoid C-Corps — unless QSBS treatment (IRC §1202) applies.
Tax form(s): Form 1120 (corporate return, separate from owner's 1040)
Liability shield: Yes — Strong liability shield per each state's corporation law. Directors, officers, and shareholders generally protected from business debts and lawsuits.
Ongoing compliance: High — Heavy ongoing compliance: board of directors, bylaws, annual meetings + minutes, separate tax return (Form 1120), annual state reports, and formal equity issuance mechanics. Generally requires a corporate attorney.
Best for: VC-backed startups planning to raise institutional equity, companies needing to issue stock options (ISOs/NSOs), foreign-ownership scenarios, and businesses pursuing QSBS tax exclusion (up to $10M capital gains exclusion under IRC §1202).
Key differentiator: The VC and QSBS vehicle. Institutional investors and accelerators (Y Combinator, a16z, etc.) require Delaware C-Corps as a condition of investment. QSBS treatment under IRC §1202 can shelter up to 100% of capital gains on exit — a massive benefit for early-stage shareholders.
Verdict: Best for: VC-backed startups, equity-issuing companies, or founders pursuing QSBS treatment — not appropriate for most small businesses

Decision framework

How to choose the right entity type

Start with the liability question — not the tax question Most people frame the entity decision as a tax choice first. That's backwards. Step one: assess your liability exposure. Do you have clients who could sue you? Do you carry business debt? Do you operate in a regulated industry? If yes to any of these, an LLC (or stronger) is justified on liability grounds alone, independent of any tax analysis. A sole prop is appropriate only when liability risk is genuinely minimal — e.g., a very early-stage idea, a low-risk hobby business, or a short-term experiment.
Default to LLC for most small businesses For the vast majority of freelancers, consultants, service businesses, e-commerce operations, and real estate investors: the LLC is the right answer. It costs $50–$300 to form, has minimal ongoing compliance, and provides the liability shield you need. The decision tree is simple: if you're not a sole prop for step 1, you're probably an LLC.
Add the S-Corp election when income crosses ~$80K net Once your LLC generates $80,000 or more in net annual profit (after all legitimate deductions), run the S-Corp math with your CPA. The core calculation: reasonable W-2 salary × 15.3% = SE tax savings on the spread between salary and total distributions. At $120K net with a $60K salary, that's ~$9,200/year. The payroll overhead (software or accountant: $500–$2,000/year) should be well under that savings. File IRS Form 2553 — it's free and takes 10 minutes.
Choose C-Corp only if you're raising institutional equity or targeting QSBS If you're building a venture-backed company, planning to raise from institutional angels or VCs, or want to issue employee stock options, you'll need a Delaware C-Corp. Form it through a startup-focused attorney or formation service (Stripe Atlas, Clerky, etc.). Budget for the higher ongoing cost: Delaware franchise taxes ($400/yr minimum), a corporate attorney, cap table management, and board formalities. Don't form a C-Corp because you heard it's 'more professional' — the double-tax structure is genuinely worse for businesses that aren't on the equity-growth path.
Pick your formation state (for LLCs) For most small businesses: form in the state where you primarily operate. There's no meaningful benefit to forming a Wyoming or Delaware LLC if you're doing business in Texas — you'll pay both Wyoming/Delaware fees and Texas foreign-qualification fees. The 'form in Wyoming for privacy' argument applies mainly if you're a non-US resident or specifically want nominee-member anonymity. For US residents, form in your home state unless you have a specific reason not to.

FAQ

LLC vs S-Corp vs sole prop vs C-Corp — common questions

Should I form an LLC or stay a sole proprietor?

If you're earning money from a business activity and have any exposure to lawsuits or business debt, an LLC is worth the $50–$300 formation cost. The core benefit: an LLC separates your personal assets (home, car, savings) from your business liabilities. A sole proprietorship has zero protection — if a client sues you or a vendor sends a collections notice, your personal assets are on the table. The exception: very early-stage side projects with minimal revenue and no realistic liability exposure. In that case, operating as a sole prop while testing your idea is perfectly reasonable — you can convert to an LLC later with a simple state filing.

What's the difference between an LLC and an S-Corp?

An S-Corp is not a separate entity type — it's a federal tax election (IRS Form 2553) that an LLC or corporation can make. The structural difference: an S-Corp requires the owner-operator to pay themselves a 'reasonable' W-2 salary, with FICA payroll taxes (15.3%) applied only to that salary. Additional profit is distributed without FICA — which is the self-employment tax savings. An LLC without the S-Corp election applies the 15.3% self-employment tax to all net profit. Bottom line: if your LLC is generating $80K+ in annual net profit, an S-Corp election typically saves $5,000–$10,000/year in SE tax, but adds payroll complexity and compliance cost.

Do I need an LLC if I'm a freelancer?

Not legally required, but often worth it. Freelancers with client contracts, deliverables, and professional liability exposure (web developers, designers, consultants, writers) benefit from an LLC's liability shield. If a client claims your work caused them financial harm and sues, an LLC keeps that lawsuit from reaching your personal assets. The cost is low: $50–$300 to form plus ~$100–$150/year for a registered agent. The real question is whether your liability risk justifies the overhead. Low-risk freelancers (tutoring, crafts, social media posting) may reasonably operate as sole props. Higher-risk professionals (software, legal research, financial writing) should probably form an LLC.

When should I elect S-Corp status?

The standard rule of thumb: when your LLC generates $80,000+ in annual net profit after deducting all legitimate business expenses. Below that threshold, the payroll overhead (QuickBooks payroll or an accountant: $500–$2,000/year) often exceeds the SE tax savings. Above it, the math reverses. Example: $120,000 net profit, $60,000 reasonable salary. SE tax savings vs. a straight LLC: 15.3% × $60,000 = $9,180/year — well worth the payroll overhead. The election must be filed on IRS Form 2553 within 75 days of forming your entity, or by March 15 of the tax year for which the election takes effect. Talk to a CPA before electing — 'reasonable compensation' benchmarks are IRS-audited.

Is an LLC better than a sole proprietorship for taxes?

By default, a single-member LLC is taxed identically to a sole proprietorship — both report income on Schedule C and pay the 15.3% self-employment tax on net profit. The LLC doesn't save you taxes on its own. The tax advantages come from the S-Corp election (available to an LLC at ~$80K+ net), not from the LLC structure itself. The LLC's value is the liability shield and legal separation, not a tax benefit in basic form.

When should I form a C-Corp instead of an LLC?

Three scenarios justify a C-Corp: (1) You're raising institutional equity (venture capital, angel syndicates, accelerators). Nearly all institutional investors require a Delaware C-Corp as a condition of investment — they want preferred stock, convertible notes, and a standard cap table structure. (2) You plan to issue employee stock options (ISOs/NSOs). ISO tax treatment requires a C-Corp. (3) You're targeting QSBS treatment (IRC §1202). Qualified Small Business Stock allows shareholders to exclude up to $10 million in capital gains (or 10× basis, whichever is greater) on a qualifying C-Corp exit. For most solo operators and small businesses, these scenarios don't apply — the 21% corporate tax plus dividend double-taxation makes C-Corp the wrong choice.

Can I change from a sole prop to an LLC later?

Yes, and it's straightforward. To convert from a sole proprietorship to an LLC: (1) File Articles of Organization with your state's Secretary of State ($50–$300). (2) Get a new EIN from the IRS (free, online) — even if you had one as a sole prop. (3) Open a business bank account in the LLC's name. (4) Transfer contracts and assets to the LLC. (5) Notify clients, vendors, and your bank of the change. There is no penalty for the conversion. Your old sole-prop EIN becomes invalid for the LLC; you need a fresh one. The conversion doesn't require a tax year change — the LLC just starts when you file the Articles.

Does an LLC protect my personal assets?

Yes — if you maintain proper separation between personal and business finances. An LLC's liability shield is strong but not absolute. It can be 'pierced' (i.e., ignored by a court) if: you commingle personal and business funds in the same account, you personally guarantee business loans or contracts, you use the LLC for fraud, or you fail to maintain basic formalities (separate bank account, accurate records). For the shield to hold, you need a dedicated business bank account, separate records, and you should never personally guarantee business obligations unless absolutely necessary. With those basics in place, an LLC provides genuine protection: lawsuits against your business generally cannot reach your home, car, or personal savings.
