One of the first real decisions you face when you start working for yourself is what legal form your business should take. The choice sounds intimidating, but for most people it comes down to three options: stay a sole proprietor, form an LLC, or elect S-corporation tax treatment. Each affects three things that matter — how much you pay in taxes, how exposed your personal assets are if the business is sued or owes money, and how much paperwork you have to keep up with.
Sole Proprietorship: The Default
If you start earning money on your own and do nothing else, you are a sole proprietor. There is no form to file and no fee — the business and you are legally the same person. You report income and expenses on a Schedule C with your personal tax return, and you pay income tax plus self-employment tax on the profit.
- Pros — free, instant, no separate tax return, minimal record-keeping requirements
- Cons — no liability protection. If the business is sued or can’t pay a debt, your personal savings, car, and home can be at risk
- Best for — low-risk side businesses, freelancers testing an idea, and anyone whose work is unlikely to generate lawsuits or large debts
LLC: Liability Protection
A limited liability company is a legal entity separate from you. Formed at the state level (usually $50–$500 to file, plus an annual fee in many states), an LLC creates a legal wall between your business and your personal assets. If the business is sued, generally only the business’s assets are at risk — provided you keep business and personal finances properly separated.
Here is the part that confuses people: by default, an LLC does not change your taxes at all. A single-member LLC is taxed exactly like a sole proprietorship (Schedule C, self-employment tax on all profit). A multi-member LLC is taxed like a partnership. The LLC is about liability protection and credibility, not tax savings — unless you go a step further and elect S-corp treatment.
- Pros — personal liability protection, flexible, more credible to clients and lenders, can later elect S-corp tax status
- Cons — state filing fees and annual reports, must keep finances strictly separate, no tax savings by default
- Best for — businesses with real liability exposure, owners with personal assets to protect, anyone planning to grow
S-Corp: A Tax Election, Not an Entity
An S-corp is not a separate kind of company you form — it is a tax election you make (usually for an LLC) by filing IRS Form 2553. The appeal is self-employment tax savings. As an S-corp owner, you pay yourself a “reasonable salary” that is subject to payroll taxes, and you take the remaining profit as a distribution that is not subject to the 15.3% self-employment tax.
The catch is cost and complexity. You must run payroll, file a separate business tax return (Form 1120-S), and pay yourself a salary the IRS considers reasonable for your work. Those costs — payroll service, bookkeeping, an accountant — typically run $1,500–$3,000 a year. As a rough rule of thumb, the S-corp election starts to pay off once your net business profit is consistently above roughly $40,000–$60,000 a year, but the exact break-even depends on your salary and state.
- Pros — can significantly reduce self-employment tax on profits above your salary
- Cons — payroll, extra tax return, accounting costs, “reasonable salary” requirement, more IRS scrutiny
- Best for — established businesses with steady profit comfortably above the break-even point
How to Decide
- Just starting, low risk? Stay a sole proprietor until you have steady income
- Have personal assets to protect, or clients who expect an LLC? Form an LLC
- Profit consistently high and stable? Talk to a CPA about an S-corp election
The Bottom Line
Most people start as sole proprietors, move to an LLC when liability or credibility matters, and consider an S-corp election only once profit is high enough to outweigh the added cost. There is no single right answer — the best structure depends on your risk, your income, and your state’s fees. Because the tax and legal stakes are real, this is the one early decision where paying a CPA or attorney for an hour of advice usually pays for itself.
