LLC vs. sole proprietorship — the decision every new business owner faces. The core difference: an LLC separates your personal assets from business liabilities; a sole proprietorship doesn’t — you and the business are legally the same person. Here’s everything that flows from that one distinction.
What Is the Difference Between an LLC and a Sole Proprietorship?
| Sole Proprietorship | LLC | |
|---|---|---|
| Formation | Automatic, $0 | $50–$300 state filing |
| Liability | Unlimited personal | Limited to business assets |
| Taxes | Schedule C, self-employment tax | Same by default; can elect S-corp |
| Paperwork | None | Annual report in most states |
| Credibility | “Just some person” | “A real company” |
| Cost/year | $0 | $0–$800 (CA is $800!) |
Liability: The Whole Ballgame
Sole proprietor sued: the judgment targets your personal bank accounts, car, house equity — everything. LLC sued: the judgment targets business assets only (if you’ve maintained separation). Real scenarios where it matters: a client trips in your home office, your product injures someone, you breach a big contract, an employee (see hiring costs) causes damage. Where it matters less: pure digital freelancing with solid contracts and no physical risk — though even then, the LLC is cheap insurance.
Taxes: Less Different Than You’d Think
By default, LLCs are taxed exactly like sole proprietorships — pass-through, Schedule C, same self-employment tax. The LLC’s tax advantage isn’t automatic; it comes from the S-corp election available to LLCs (not sole proprietors) at higher incomes — see our freelancer structure guide for the $60k threshold. Don’t form an LLC “for tax benefits” without understanding this — the benefit is liability + future tax flexibility, not immediate savings. Either way, handle self-employment taxes correctly from day one.
The Conversion Moment (When to Switch)
Still a sole proprietor? Convert to an LLC when any of these hit: revenue crosses $30k/year (the liability exposure now dwarfs the $100–$300 formation cost), you sign contracts with liability/indemnification clauses, you hire anyone (even contractors — see hiring), you take on business debt, or a client requires it (many enterprise clients won’t contract with sole proprietors). How to convert: form the LLC in your state, get a new EIN, update contracts/bank accounts/licenses to the LLC name, and file a final Schedule C for the sole proprietorship period. Most states let you do it online in under an hour — the barrier is psychological, not procedural.
State Gotchas
- California: $800/year minimum franchise tax — the LLC costs real money annually. Factor it in.
- New York: Publication requirement ($200–$1,200 depending on county) — an annoying hidden cost.
- Wyoming/New Mexico: Popular for low fees and privacy — but if you operate elsewhere, you still register as a foreign LLC there too.
- Annual reports: Most states require them ($10–$300/year) — miss one and your LLC gets dissolved administratively.

Single-Member LLCs: The Fine Print
One owner, one LLC — special considerations: Liability: slightly weaker than multi-member (some courts have pierced single-member LLCs more readily) — maintain impeccable separation (see our bank account guide — commingling is the #1 piercing trigger). Taxes: “disregarded entity” by default — taxed exactly like a sole proprietorship (Schedule C). Paperwork: same as any LLC (annual reports, fees). Why bother then? The liability shield (even if slightly weaker, it’s vastly better than none) + credibility + the S-corp election option later. Cost-benefit: $50–$300/year for meaningful protection — the cheapest business insurance there is. Don’t: assume “LLC” alone protects you — the shield requires maintenance (separate accounts, proper contracts, annual compliance).
DBA vs. LLC: The Confusion Clarified
These solve different problems: DBA (“doing business as”): a name registration ($25–$100) — lets “John Smith” operate as “Smith Designs.” Provides: zero liability protection, zero tax benefit — just the legal right to use the name + open bank accounts in it. LLC: a separate legal entity — liability shield + credibility. You often need both: “Smith Designs LLC” operating as “Smith Creative” needs the LLC and the DBA. The sequence: form the LLC first (the entity), then file DBAs for trade names (the labels). Common mistake: “I have a DBA so I’m protected” — no. A DBA is a name tag, not a shield. If you have only a DBA: you’re a sole proprietor with a fancy name — unlimited liability included.
Professional LLCs (PLLCs): For Licensed Professionals
Doctors, lawyers, accountants, architects: many states require a PLLC instead of a regular LLC. Differences: all members must hold the relevant professional license, state board approval often required, and — critically — PLLCs don’t shield against your own malpractice (only against partners’ malpractice and general business debts). Cost: higher filing fees + board approvals ($200–$500+). Malpractice insurance: still mandatory — the PLLC is not a substitute. Check your state: requirements vary wildly (California doesn’t allow LLCs for professionals at all — LLPs instead). Your state bar/board website has the specific requirements — start there, not Google.
Tax Election Deep-Dive (S-Corp Timing)
When exactly to elect S-corp status: The threshold: consistent $60,000+ net profit (not revenue — profit). Why not earlier: payroll costs ($600–$1,200/year for a service) + admin burden exceed the tax savings below $60k. The savings math: at $80k profit, S-corp saves ~$5,000–$7,000/year in self-employment tax (pay reasonable salary ~$50k, take $30k as distributions). How to elect: Form 2553, filed by March 15 for current-year effect (or anytime for next year). The salary trap: the IRS requires “reasonable” salary — $20k salary on $100k profit triggers audits. Get a CPA: this decision has permanent consequences — $300 for advice that saves $5,000/year. See: our freelancer structure guide for the full progression. Timing matters; elect in the right year, not the early year.
The One-Person Business Decision Tree
Decide in 60 seconds: Just testing an idea? → Sole proprietor ($0, no paperwork). Earning $500+/month? → LLC ($50–$300, liability shield). Signing contracts with liability clauses? → LLC (before signing). Profit over $60k/year? → LLC + S-corp election (tax savings). Hiring anyone? → LLC (non-negotiable). Multiple owners? → Multi-member LLC + operating agreement. Licensed professional? → PLLC (check your state). That’s the entire decision. Revisit yearly (see the checkup section) — the answer changes as you grow. Most solo businesses: sole proprietor → LLC at first real revenue → S-corp election at $60k profit. Simple, sequential, correct.
Can I Change From Sole Proprietorship to LLC Later?
Yes — and it’s the most common upgrade path in small business. You start as a sole proprietor (automatic, free), then form an LLC when revenue, liability, or credibility demands it. The process: file articles of organization with your state ($50–$500), get a new EIN (the LLC is a new entity), open new business bank accounts, and update contracts, licenses, and tax registrations to the LLC name.
Timing considerations: there’s no tax penalty for converting (single-member LLC is taxed identically), so the decision is purely about liability and professionalism. Many accountants suggest converting when you hit $30–$50k in revenue, hire anyone, sign a commercial lease, or land clients who require vendor insurance — all signals that the liability shield has real value.
Don’t forget the cleanup: update your DBA registrations, notify clients of the entity change (contracts may need assignment), update business licenses and permits, and inform your insurance company. The LLC protects going forward; it doesn’t retroactively shield pre-formation liabilities.
Frequently Asked Questions
Does forming an LLC change my taxes?
Not by default — a single-member LLC is a ‘disregarded entity’ taxed exactly like a sole proprietorship (Schedule C). The tax advantage comes later via optional S-corp election at higher incomes. Formation is about liability, not taxes.
Can I transfer my business name to the LLC?
Yes — form the LLC with your business name (or file a DBA under the LLC). Check name availability with your Secretary of State first; if another business has it, you’ll need a variation. Secure domains and social handles under the new entity.
Do I need a new EIN for my LLC?
Yes — the IRS treats the LLC as a new entity requiring its own EIN, even if you’re the sole owner. It’s free at IRS.gov and takes 10 minutes. Update banks, clients, and tax accounts with the new number.
What happens to existing contracts?
They remain valid (you’re the same person doing the work), but update them to reflect the LLC as the contracting party going forward. Some contracts have assignment clauses requiring client consent — check large ones.
Is it expensive to maintain an LLC?
Modestly — annual report fees ($0–$300 in most states; California’s $800 is the painful exception), plus registered agent if you use one ($100–$300/year). Factor these into the decision, but they’re small relative to the protection.
Can a single person really have an LLC?
Absolutely — single-member LLCs are the most common type. You get full liability protection as a solo owner, provided you maintain separation (separate bank account, records). The ‘limited’ refers to liability, not headcount.
The bottom line
Sole proprietorship to test, LLC to operate. The liability shield is the entire point — taxes are the same until S-corp election. Convert at $30k revenue, first hire, or first scary contract, whichever comes first. At $50–$300 to form, the LLC is the cheapest meaningful insurance a business owner can buy.
