Single Member LLC

A single-member LLC is a limited liability company that has one member (owner). It provides limited liability protection and tax advantages. We recommend SMLLC vs sole proprietorship.

Our Single Member LLC guide will detail the benefits and teach you how to set up a single-member LLC.

Single Member LLCs: An Overview

Reasons to Form a Single-Member LLC?

The main reason to register a single-member LLC (SMLLC) is to form a separate legal entity that protects your personal assets if the business gets sued for negligence or business debts.

By having a separate entity, a single-member LLC owner has less personal liability than a sole proprietor. Business debts become the responsibility of the business, not the LLC owner.

There are other benefits to starting a single-member LLC:

  • A single-member LLC is a simple business entity to start for solo business owners.
  • Your business name is protected by the state (only one name can be registered with the state).
  • SMLLCs are disregarded entities for federal income tax purposes (You file personal income tax returns, paying business income tax on Schedule C of federal tax form 1040)
  • Because your business has an employer identification number, i.e. a taxpayer identification number, that is separate from your social security number, you can establish business credit and get credit cards in your business name.
  • Though single-member LLC owners must pay self-employment tax, filing tax forms Schedule SE of federal tax form 1040, they can deduct half of self-employment business taxes on Schedule C of their personal tax return as a business expense, thereby reducing their overall tax burden.
  • Single-member LLCs can hire employees but like any other business must withhold payroll taxes, FICA, and medicare. Single-member LLC owners operate their SMLLC similar to the way a sole proprietor does (can hire employees, paying income tax on the owner's personal tax return, etc).

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: An SMLLC 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, an SMLLC 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.

Single-member LLCs are formal business structures that are taxed similarly to a sole proprietorship, but single-member llcs are designed to protect personal assets and to legally separate the business from its owner. Most serious business owners choose to form this type of business entity because an LLC legally separates the owner's personal assets from the business and because its easy to pay taxes.

For tax purposes, the sole owner of an SMLLC simply files a personal income tax return when filing taxes since an SMLLC is a pass-through entity. Both federal taxes and state income tax are paid by the single owner of 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 from business income 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. Thus the LLC is a disregarded entity, taxed like a sole proprietorship.

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.

SMLLC 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 SMLLC. Learn more about choosing an S corporation in our LLC vs. S Corp guide.

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.

An SMLLC 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 an SMLLC operating agreement
  • Sign business documents in your LLC’s name
  • Stay in good standing with the state
