Single Member LLC

Everything You Need to Know

A single-member LLC is a limited liability company (LLC) with just one member.

LLCs are the most popular formal business structure because they protect business owners from being held personally responsible for business liability and losses and offer increased credibility and pass-through taxation.

Why Form a Single-Member LLC?

A single-member LLC (SMLLC) only has one owner, known as a member. The owner gains limited liability protection when they form their LLC. This means they aren't personally responsible for the debt of the business.

The IRS regards a single-member LLC as a disregarded entity for tax purposes. This is a fancy way of saying the IRS ignores the LLC from a tax point of view and only taxes the owner directly for the profits of the LLC. This is known as pass-through taxation.

Single-Member LLC Pros and Cons

A single-member LLC is a formal business structure that offers several advantages. Here are some pros and cons of starting an LLC:


  • Limited liability protection
  • Greater privacy (the business name is listed, not the owner's name)
  • Pass-through taxation
  • Taxation can be reduced
  • Fewer publicly available records
  • Not required to hold annual meetings or keep minutes
  • No formalities are required for maintaining the LLC
  • Flexible management structure

SMLLC Benefits vs. Other Business Structures

Choosing a single-member LLC over another business type such as a sole proprietorship or a corporation offers several benefits, including:

  • Investment Opportunities: Registered businesses often carry increased stature in the minds of potential investors. It is generally more difficult to attract investment funds to a sole proprietorship than to an LLC
  • Credibility: As a single business owner, registering as an LLC can also add credibility to your operation in the eyes of prospective customers. Many people feel more comfortable working with a business rather than an individual.
  • Flexible Taxation: A single-member LLC can choose to be taxed as either a sole proprietor or a corporation, depending on what format will produce the best financial outcome. This decision should be made under the advice of a tax professional.
  • Flexible Ownership: Unlike a sole proprietorship, a single-member LLC can be owned by either a person or a single entity such as another LLC or a corporation.
  • Ease of Doing Business: While a single-member LLC offers the limited liability protection of a corporation, it is not required to follow the same formalities, such as issuing stock, creating and adopting bylaws, and holding annual shareholder meetings.

Sole Proprietorship vs. Single-Member LLC

A sole proprietorship is an informal business structure that doesn't have to register with the state. Sole proprietors assume all of the business's risks and debts. For this reason, only low-risk or low-profit businesses should be sole proprietorships.

A single-member LLC is a formal business structure that is taxed similarly to a sole proprietorship, but an LLC is designed to protect personal assets and to legally separate the business from its owner. Most serious business owners choose to form an LLC because an LLC legally separates the owner's personal assets from the business.

DBA vs. Single-Member LLC

A "doing business as" (DBA) name isn't a type of business structure. A DBA is a fictitious name that can be used by sole proprietors and other business entities for branding purposes.

A common misconception held by business owners is thinking that when they get a DBA, they are creating a formal business structure with liability protection.

But, this is not the case — they are essentially creating a sole proprietorship with a DBA name for branding.

Single-Member LLC Taxes

Single-member LLCs have the benefit of being able to choose between being taxed as a disregarded entity, S corporation, or C corporation. As C corporation taxation is rarely used, we will focus on disregarded entities and S corporations.

SMLLCs and Pass-Through Taxation

The IRS treats single-member LLCs as "disregarded entities" by default, meaning they undergo pass-through taxation.

With pass-through taxation, the company's profits pass through to its members to be reported on their personal tax returns rather than being taxed at the corporate level. All profits are only taxed once at the owner's individual income tax rate.

SMLLCs and Self-Employment Tax

Under the default LLC tax status, the single-member LLC profit passes through to the owner’s individual tax return and is subject to self-employment tax and income taxes.

Single-member LLC owners have the option to elect S corporation tax status. Electing S corp status allows business owners to be treated as employees of the business for tax purposes.

In an S corp, the business must pay the owner "reasonable compensation" or "reasonable salary" per IRS guidelines. The owner pays income taxes and payroll taxes (i.e., FICA and Medicare) on their salary. Distributions are only subject to income taxes (i.e., no FICA).

Electing S corporation status won’t make sense for every single-member LLC. Learn more about choosing an S corporation in our LLC vs. S Corp guide.

Your LLC registered agent will accept legal documents and tax notices on your LLC's behalf. You will list your registered agent when you file your LLC's Articles of Organization.

Step 4: File Your LLC's Articles of Organization

The Articles of Organization, also known as a Certificate of Formation or a Certificate of Organization in some states, is the document you will file to officially register an LLC with the state.

Step 5: Create an LLC Operating Agreement

An LLC operating agreement is a legal document that outlines the ownership and member duties of your LLC.

Step 6: Get a New EIN

An Employer Identification Number (EIN) is a number that is used by the US Internal Revenue Service (IRS) to identify and tax businesses. It is essentially a Social Security number for a business.

EINs are free when you apply directly with the IRS. Visit our EIN guide for instructions for getting your free EIN.

Maintaining Your SMLLC's Corporate Veil

The corporate veil is the limited liability protection that is created when you form an LLC or corporation. But, starting an LLC or corporation doesn’t ensure that you’ll have liability protection when you need it. 

In order to maintain liability protection, you must maintain the corporate veil. The corporate veil is said to be pierced when the business owner of the LLC no longer has limited liability protection. This can occur for several reasons. The most common (and preventable) is keeping personal and business finances separate. Starting a business checking account is the first step.

A single-member LLC must take greater precautions than a multi-member LLC when it comes to piercing the corporate veil. This is because owners are often managers. And as such, they may commingle personal and business finances.

To prevent piercing the corporate veil:

  • Do not commingle personal and business finances
  • Create and maintain single-member LLC operating agreement
  • Sign business documents in your LLC’s name
  • Stay in good standing with the state
