LLC vs Sole Proprietorship vs S Corp for Freelancers
"Should I form an LLC?" is one of the first questions new freelancers ask, usually followed by "and what about an S corp?" The two are often confused. An LLC is a legal entity you create under state law. An S corporation is a federal tax election. You can have an LLC that is taxed as an S corp, an LLC that is not, or a corporation that is. This guide separates the legal question from the tax question so you can answer each one on its own.
Sole proprietorship: the default
If you start freelancing and do nothing else, you are a sole proprietor. You report business income and expenses on Schedule C, pay self-employment tax on the profit, and can use your own name or register a "doing business as" (DBA) name in most states.
- Pros: no formation cost, no separate tax return, minimal paperwork.
- Cons: no legal separation between you and the business. If the business is sued or owes a debt, your personal assets are exposed.
Even as a sole proprietor, you can get a free Employer Identification Number (EIN) from the IRS to give to clients instead of your Social Security number, and you should open a separate bank account for business money.
The LLC: a legal shield (with limits)
A limited liability company is formed by filing articles of organization with your state and paying a fee. The main benefit is liability protection: business debts and many claims against the business generally stay with the business rather than reaching your house or personal savings.
Two limits are important to understand:
- It does not protect you from your own professional mistakes. If you personally perform negligent work, you can usually still be held personally liable. That is what professional liability insurance is for.
- The shield can be lost if you treat the LLC as an extension of yourself: mixing personal and business money, ignoring state filings, or signing contracts in your own name rather than the LLC's.
Tax-wise, a single-member LLC changes nothing by default. The IRS treats it as a "disregarded entity," so you still file Schedule C and still pay self-employment tax on all profit. Multi-member LLCs are taxed as partnerships by default.
Costs people forget
- State fees vary a lot. Formation fees range from under $100 to several hundred dollars, and some states add annual fees or minimum taxes. California, for example, charges LLCs a minimum annual franchise tax of $800.
- Annual reports and a registered agent are required in most states.
- Publication requirements in a few states (New York is the best known) can add hundreds of dollars.
On federal beneficial ownership (BOI) reporting: in March 2025 FinCEN exempted companies formed in the United States from the requirement. Rules in this area have changed several times, so check FinCEN's site for the current position.
The S corp election: a tax strategy
By filing Form 2553, an LLC (or corporation) can elect to be taxed as an S corporation. The appeal is self-employment tax:
- As an S corp owner who works in the business, you must pay yourself a reasonable salary through payroll. Social Security and Medicare taxes apply to that salary, just like any employee.
- Profit above the salary can be taken as a distribution, which is subject to income tax but not to Social Security and Medicare taxes.
A simplified example
Alex, a consultant, has $120,000 of profit. As a sole proprietor or default LLC, roughly all of that is subject to self-employment tax: about $120,000 × 92.35% × 15.3% ≈ $16,955.
As an S corp paying a reasonable salary of $70,000, payroll taxes (employer and employee shares combined) are about $70,000 × 15.3% ≈ $10,710. The remaining $50,000 is a distribution without payroll tax. The gross saving is roughly $6,000.
Now subtract the costs: a payroll service, a separate corporate tax return (Form 1120-S) that usually means higher accounting fees, state S corp fees or taxes in some states, and possible state unemployment insurance. Lower salary also means lower Social Security earnings on your record and can reduce how much you can put into a retirement plan. The net saving might be a few thousand dollars, or close to nothing.
Reasonable salary is not optional
The IRS expects the salary to reflect what you would pay someone else to do your job. Paying yourself an unrealistically low salary to maximize distributions is a well-known audit issue, and the IRS can reclassify distributions as wages.
When does each choice make sense?
| Situation | Often a good fit |
|---|---|
| Just starting, low risk, testing the market | Sole proprietorship with an EIN and separate bank account |
| Real liability exposure, signed contracts, physical work, or assets to protect | Single-member LLC, plus appropriate insurance |
| Steady profit well above a reasonable salary for your role | LLC with S corp election, after running the numbers with a CPA |
| Volatile or low profit | S corp usually not worth the overhead yet |
Many tax professionals start the S corp conversation once profit is consistently high enough that the payroll-tax saving clearly exceeds the added costs; the break-even point depends on your state, your field's typical salary and your accountant's fees.
Practical steps if you form an LLC
- Choose a name and check availability with your state's business filing office.
- File articles of organization and appoint a registered agent.
- Write a simple operating agreement, even as a single member; banks often ask for it.
- Get an EIN from IRS.gov (free; avoid sites that charge for it).
- Open a business bank account and run all business money through it.
- Update contracts, invoices and your W-9s to the LLC's name.
- Calendar your state's annual report and fee deadlines.
Bottom line
Form an LLC for legal reasons, not tax reasons. Consider the S corp election for tax reasons, but only when your profit is stable and high enough that the savings survive the extra costs. Neither replaces insurance or good contracts.
