Sole proprietor vs LLC for freelancers

A sole proprietorship in the US (and the rough equivalent in most other countries) is the default legal structure when you do business under your own name. There is no separate legal entity — you and the business are the same. You report business income on your personal tax return (Schedule C in the US), pay self-employment tax on net earnings, and your personal assets are the same as your business assets. There's no formation paperwork, no annual filing fee, and no business bank account requirement. The simplicity is the appeal: you can start a sole proprietorship by deciding you have one.

An LLC (Limited Liability Company) is a formal legal entity registered with your state. It's separate from you legally — meaning if the business is sued, in most cases the lawsuit reaches only the business's assets, not your personal home, savings, or other belongings. LLCs require state registration (filing fees range $50-$500 depending on state), an operating agreement, a separate business bank account, and an annual filing or franchise tax in most states ($0-$800/year depending on state — California's $800 minimum is the highest of any state). Tax-wise, an LLC by default is a 'pass-through' entity in the US, meaning income flows to your personal tax return just like a sole proprietorship — but you can elect S-Corp treatment for potential tax savings at higher income levels.

The biggest practical difference between a sole proprietor and an LLC is liability. As a sole proprietor, if a client sues you for a design that infringed someone's copyright, or a website that crashed during their launch, the lawsuit is against you personally — your house, your car, your savings are all on the line. With an LLC, the lawsuit is against the LLC, and your personal assets are typically protected (assuming you've maintained the LLC properly — see the next section). Liability exposure varies hugely by profession. A copywriter has lower exposure; a developer building production systems for clients has higher exposure; anyone working with regulated industries (health, finance, legal) has the highest. The higher your exposure, the stronger the case for an LLC.

LLC liability protection is often called 'piercing the corporate veil' when courts decide it doesn't apply. To preserve protection, you need to keep your LLC operationally distinct from yourself: separate business bank account, no commingling of personal and business funds, formal contracts in the LLC's name, an operating agreement (even for single-member LLCs), and reasonable record-keeping. Freelancers who form an LLC and then use the business account to pay their grocery bill have, in a court's view, treated the LLC as their own pocket — and the protection can vanish. The LLC works only as well as you operate it.

By default, a single-member LLC in the US is taxed identically to a sole proprietorship — pass-through to your personal return, with self-employment tax on net earnings. The structural tax difference comes when you elect S-Corp treatment for the LLC, which can reduce self-employment tax exposure on income above a 'reasonable salary' threshold. This typically becomes economically meaningful at net earnings of roughly $40-$80k+, depending on state and accounting fees. The S-Corp election is its own decision and adds complexity (payroll, additional filings) — it's worth modelling with a CPA when your income reaches that range.

A reasonable rough rule for US freelancers: form an LLC when one of these is true. (1) Your annual freelance income exceeds $30-$50k — at that point, the formation cost is small relative to liability exposure. (2) You're working in a profession with meaningful liability (development, regulated industries, anything safety-related). (3) You have personal assets you'd lose sleep over if a lawsuit reached them. (4) You're planning to scale beyond yourself — hire contractors, take on partners, or build something with employees. Below those thresholds, sole proprietorship is usually fine, and the simplicity is worth keeping.

The structures available outside the US vary significantly. UK freelancers typically choose between sole trader and a Limited Company (Ltd) — the analog of an LLC, with similar liability/tax trade-offs. EU freelancers have country-specific structures (Auto-Entrepreneur in France, Einzelunternehmer/GmbH in Germany, etc.). Australian freelancers choose between sole trader and PTY LTD. The principles are similar — start simple, formalise when income or liability justifies it — but the specific thresholds and tax treatment vary widely. Talk to an accountant in your jurisdiction; the answer that's right in the US is often wrong elsewhere.
