A single-member LLC (SMLLC) is the simplest way to protect your personal assets without changing how you file taxes. One owner, liability protection, Schedule C filing — the best of both worlds for freelancers, consultants, and solo business owners.

Quick answer:A single-member LLC costs $35–$520 to form and files taxes on a Schedule C exactly like a sole proprietorship — with one critical difference: your personal assets are protected from business lawsuits and debts. For most solo business owners with clients, it's worth the filing fee.
You're not alone. The U.S. has 30,427,808 solo businesses with no employees, averaging $57,611 in annual receipts. Most are unincorporated sole proprietors — forming a single-member LLC is how many of them add liability protection without changing how they file taxes.

Frequently Asked Questions
A single-member LLC (SMLLC) is a limited liability company with exactly one owner (member). It provides the same personal liability protection as a multi-member LLC — your personal assets are separated from business debts, lawsuits, and contract disputes. By default, the IRS treats a single-member LLC as a 'disregarded entity,' meaning all income and expenses are reported on the owner's personal tax return via Schedule C, exactly like a sole proprietorship. Unlike a sole proprietorship, however, the LLC is a formal legal entity registered with the state, giving you a legal separation between your personal finances and your business that a sole proprietor simply does not have. Formation costs $35–$520 depending on your state. Turnaround is not something most states commit to: 34 of the 50 publish no standard processing time at all, while seven approve online filings immediately.
Most states do not legally require a single-member LLC to have an operating agreement, but you should have one regardless. Banks commonly require an operating agreement to open a business checking account in the LLC's name. It also documents that the LLC is a separate legal entity from you personally, which helps preserve the liability shield if your business is ever sued. A well-maintained liability shield requires keeping finances separate and having paperwork that proves the business is real — an operating agreement is exhibit A. For a single-member LLC, the document is simple: it establishes your name as the sole member, your ownership percentage (100%), your capital contribution, and how the LLC will be managed. You can draft one in an afternoon or use a template.
By default, the IRS treats a single-member LLC as a disregarded entity — essentially invisible for tax purposes. All business income and expenses flow to your personal Form 1040 via Schedule C. You pay self-employment tax (15.3% on the first $168,600 of net profit in 2024, then 2.9% Medicare on income above that) plus ordinary income tax at your personal rate. You can elect to have the LLC taxed as an S-Corp by filing IRS Form 2553, which becomes advantageous once annual net profit consistently exceeds $60,000–$80,000. The S-Corp election lets you split income between a salary (SE tax applies) and a distribution (SE tax exempt), saving $3,000–$10,000 per year depending on your income level and state.
Yes. A single-member LLC can hire employees, obtain a separate Employer Identification Number (EIN) for payroll purposes, and withhold federal and state employment taxes. The member is not an employee by default — you pay yourself through an owner's draw, or through payroll if you have elected S-Corp status. Employees are separate from members and are subject to all standard employment rules: minimum wage, overtime, W-2 issuance at year-end, and payroll tax withholding. Hiring employees does not change your LLC's tax classification unless you also elect S-Corp status. You will need a payroll system (QuickBooks Payroll, Gusto, ADP, etc.) and must make quarterly payroll tax deposits with the IRS.
Adding a second member converts your single-member LLC into a multi-member LLC and triggers an important tax change: the IRS automatically reclassifies the entity from a disregarded entity to a partnership. You must now file Form 1065 (Partnership Return) and issue Schedule K-1s to each member, who then reports their share of income on their personal returns. This is more complex and typically requires a CPA for annual filing. You will also need a revised operating agreement reflecting the new ownership percentages, profit allocations, voting rights, and exit provisions — a document far more complex than a single-member operating agreement. Notify your bank and update any business licenses to reflect the new membership structure. The state filing itself typically does not require amendment for adding a member unless the LLC is manager-managed.
Yes, for most freelancers with any client revenue or signed contracts. A single-member LLC separates your personal assets — bank accounts, home, savings, vehicles — from client disputes, contract lawsuits, and business debts. The tax filing is nearly identical to a sole proprietorship (Schedule C on your personal return), so there is minimal added complexity. Formation costs $35–$520 depending on your state. The primary ongoing obligation is your state's annual report, which most states require annually or biennially and costs $0–$520 depending on the state. If your freelance income grows above $60,000–$80,000 per year, consider adding an S-Corp election to reduce self-employment tax on the distribution portion of your income.
