When you start working for yourself, you are a sole proprietor by default without filing anything. Forming a limited liability company, or LLC, is a deliberate step that changes your legal standing but often not your taxes. The distinction matters most when something goes wrong and someone comes after your assets. This guide clarifies what each structure does and does not do, so you can choose with clear eyes.
The sole proprietorship default
A sole proprietorship is not really a separate entity; it is simply you, doing business. There is no paperwork to create it and no legal wall between you and the business. You report profit on Schedule C with your personal tax return, and business debts are your personal debts. It is simple and cheap, but that simplicity is exactly what leaves your personal assets exposed.
What an LLC adds
An LLC is a legal entity registered with your state, and its main benefit is limited liability. If the business is sued or cannot pay its debts, creditors generally can reach only the business assets, not your home or personal savings. That protection depends on keeping business and personal finances truly separate, a topic worth its own attention. An LLC also lends credibility with clients, banks, and vendors.
Taxes are usually the same by default
A common misconception is that an LLC automatically lowers your taxes, but by default it does not. A single-member LLC is a disregarded entity, taxed exactly like a sole proprietorship on Schedule C, and still owes self-employment tax on profits. The real tax flexibility comes later, when an established LLC elects to be taxed as an S corporation to potentially reduce self-employment tax. Choosing an LLC is primarily a liability decision, not a tax one.
Weighing cost against protection
An LLC carries formation fees and, in many states, annual fees or franchise taxes, plus a bit more paperwork. For a low-risk side hustle with few assets to protect, a sole proprietorship may be perfectly reasonable to start. As revenue, contracts, and potential liability grow, the protection of an LLC becomes worth the cost. Many owners begin as sole proprietors and convert once the business is established.
A photographer operating as a sole proprietor is sued after equipment injures a guest, and her personal savings are exposed. Had she formed an LLC and kept separate finances, the claim would generally be limited to business assets. The state filing fee of a few hundred dollars looks small against that risk.
Key takeaways
- A sole proprietorship is automatic and free but offers no liability protection.
- An LLC creates a legal shield around your personal assets if the business is sued.
- By default, a single-member LLC is taxed exactly like a sole proprietorship.
- The main reason to form an LLC is liability protection, not lower taxes.
Common mistakes
- Believing an LLC automatically cuts your tax bill, which it does not by default.
- Forming an LLC but commingling funds, which can void the liability protection.
- Delaying an LLC long after the business has real assets and contracts at stake.
FAQ
Do I still pay self-employment tax with an LLC?
Yes. A default LLC passes profit through to you, and that profit remains subject to self-employment tax just like a sole proprietorship.
Can I switch from sole proprietor to LLC later?
Absolutely. Many owners start as sole proprietors and register an LLC once revenue and liability grow enough to justify it.
