When starting a new project, it is essential to correctly choose the business structure. One-person LLCs are usually a highly used option by entrepreneurs without partners due to their numerous advantages.
In this guide, we are going to see everything you need to know so you can make a decision about whether the one-person LLC is the best option for you. We will see what it is, what its advantages and disadvantages are, how it works and how it compares to other business structures that you could also use.
What is a Sole Proprietorship LLC?
A single member LLC or "Single Member LLC" is a limited liability company with a single voting member. That member is the owner of the LLC.
In contrast, multi-member LLCs have multiple partners who hold percentages of ownership of the business, and who vote to make important decisions.
Regardless of the number of owners, all LLC offer:
- Liability Protection:Business owners are protected from personal liability for their company's debts or liabilities. Instead, the liability falls on the LLC, meaning the business is considered its own legal entity.
- "Pass Through Taxation": The LLC does not pay taxes as a business, but rather the tax liability passes through to its members' personal tax returns. If you are a non-resident of the USA, your LLC will not pay taxes in the USA.

- Choose the state in which you want to register your One-Person LLC: There are 50 states in which you can register an LLC, and each has advantages and disadvantages.
- Selecting a name for your Sole Proprietorship LLC: Your business name must be distinctive within the state and include the words "Limited Liability Corporation" (LLC). The state prohibits the use of several terms.
- Get a Registered Agent: A person who is at least 18 years old and resides in the state in which you incorporate your LLC will act as the registered agent. He or she will be responsible for providing members with official documentation. Many companies offer the services of a registered agent.
- Sign the Articles of Organization: The "Articles of Organization" must be completed and submitted. You can obtain this form on each state's website to create your LLC. Here you will find all the essential data about your company. Each state has a different rate for this.
- Create the LLC operating agreement, which describes how the entity will be managed. It is not required, but it is highly recommended.
- Apply for an EIN: For example, to create a business bank account or hire staff, you will need your EIN. A corporate bank account is essential for keeping your personal assets separate from those of the corporation. In addition, accounting will be considerably simplified.
- Meet your annual obligations: Your obligations will vary by state (annual reports, taxes, IRS filings). Failure to comply with responsibilities may result in fines or closure of the LLC.
How do taxes work for a Single-Person LLC?
By default, a Sole Proprietorship LLC is taxed the same way as a Sole Proprietorship: the IRS does not separate the LLC from its owner. The owner will pay the income taxes of the LLC on his personal tax return. It is the concept of "Pass-Through Taxation" that we mentioned previously.
However, you can also choose to be taxed as:
- A C Corporation: You must file IRS Form 8832 to confirm your tax status, and then report all business income on IRS Form 1120. That income will be taxed at the corporate tax rate. For this reason, single-member LLCs rarely choose to file as C corporations.
- An S Corporation: You will need to file the IRS Form 2553 and then report all business income on IRS Form 1120S. Like the LLC, taxing as an S corporation offers pass through taxation. The difference is that when you are taxed as an S corporation, you do not have to pay Self Employment Tax.
Simply put, you have the final say on how your LLC is taxed and a tax professional can help you determine what is best for you. But we've broken down the basics for you.
