Starting a business alone can feel overwhelming, but forming a Single-Owner LLC—also called a Single-Member LLC (SMLLC)—is one of the simplest and most flexible ways to do it in the U.S.

This guide will walk you through what a single-owner LLC is, how it works, its advantages, and what you need to consider before forming one.
What Is a Single-Owner LLC?
A Single-Owner LLC is a Limited Liability Company that has only one owner, also known as a member. It offers the same liability protection as multi-member LLCs, shielding your personal assets from business debts or lawsuits.
Despite being a one-person business, a single-member LLC is legally separate from its owner, which makes it a popular choice among freelancers, consultants, and small business owners.
How Does a Single-Member LLC Work?
When you form a single-member LLC, you create a legal business entity registered with your state. Here’s how it typically works:
- You file Articles of Organization with the Secretary of State.
- You choose a unique LLC name.
- You get an EIN (Employer Identification Number) from the IRS.
- You can open a business bank account under the LLC’s name.
- You operate the business independently but legally distinct from yourself.
Tax-wise, a single-member LLC is considered a disregarded entity by default. This means income and expenses “pass through” to your personal tax return (Form 1040, Schedule C). However, you can choose to be taxed as an S Corporation if that better suits your situation.
Benefits of a Single-Owner LLC
Forming a single-member LLC comes with key advantages:
- Personal Liability Protection: Your personal assets (home, car, savings) are usually safe from business lawsuits or debts.
- Simple Tax Filing: Income is reported directly on your personal return, making taxes easier than a corporation.
- Professional Image: Operating as an LLC gives your business more credibility.
- Easy to Manage: No board of directors, no complicated annual meetings—just you running your business.
- Flexibility in Tax Treatment: You can elect to be taxed as an S Corp if your profits grow.
Downsides to Consider
While it’s a great option for many, here are a few potential drawbacks:
- Self-Employment Tax: You’ll owe Social Security and Medicare taxes on your net earnings unless you elect S Corp taxation.
- Limited Funding Options: Investors usually prefer corporations, so funding may be harder to secure.
- State Fees & Requirements: Some states have annual filing fees or franchise taxes (e.g., California’s $800 minimum annual tax).
