Single-Member LLC
A single-member LLC is a way you can set up your business that provides you with some limited liability protection than you would receive with a sole proprietorship.
What is a Single-Member LLC?
A single-member LLC is one of the most common forms of small business in the United States. A limited liability company (LLC) is often partnerships with additional liability protection. A single-member limited liability company is an LLC with one owner. The word single-member recognizes that the LLC has one owner, also known as a member. Single-member LLC is registered in the state where the company does the bulk of its business.
Many states do not allow anyone to form a single-member LLC. The IRS considers these LLCs as disregarded entities and will tax them as a sole proprietorship.
Since LLCs were created to be partnerships, the IRS only agrees to recognize single-member LLCs with the condition that you have to abide by some partnership rules.
How a Single-Member LLC Compares to a Multi-Member LLC
When evaluating a single member LLC vs multi member LLC, the core distinction lies in ownership structure. A single-member LLC (SMLLC) has one owner, while a multi-member LLC (MMLLC) has two or more. This difference impacts management, tax filing, liability protection, and operational flexibility.
Here are some key comparisons:
1. Ownership and Control
- SMLLC: The single owner has complete control over business decisions.
- MMLLC: Decisions are shared among members based on their ownership percentage or the terms outlined in the operating agreement.
2. Taxation
- SMLLC: Default treatment is as a disregarded entity (taxed like a sole proprietorship). Income is reported on the owner’s personal tax return via Schedule C.
- MMLLC: Treated as a partnership by default. Must file Form 1065 and issue K-1s to each member.
3. Liability ProtectionBoth types offer limited liability protection. However, courts have historically been more likely to uphold the liability shield in multi-member LLCs than in single-member LLCs, especially where formalities are not maintained.
4. Flexibility in Business StructuringMMLLCs may attract investors or co-founders, enabling faster growth and division of labor. SMLLCs are simpler for solo entrepreneurs who want full autonomy.
Activities of a Single-Member LLC Owner
An owner will take cash from the business for any personal expenses and does not get a salary. He or she is not considered an employee. He or she will put cash into the business as it is needed. The bulk of the funds contributed to the LLC will come from the owner’s personal finances.
Advantages of a Single-Member LLC
A SMLLC is formed in a single state. Part of being approved is the registration of the business’ name. No other company may have the same name. Although sole
proprietors can register a business name with the state, it is a different process.
Much like traditional LLCs, single-member can choose to be taxed like a corporation. You can continue to report your self-employment income on a Schedule C since you are a disregarded entity. This will save money on your tax preparation costs.
There are no minimum tax fees for a single-member LLC. In states with high minimums for traditional LLCs, you can save a lot of money.
A single-member LLC is easier to manage than a traditional LLC. It continues to offer many benefits of limited liability, such as the minimum regulatory requirements.
Both single-member and multiple-member LLCs do not have to have directors or officers or hold re-elections. There are also no annual meetings of the board and stockholders.
It is rather simple to change a traditional LLC or S corporation to a single-member if you want to have a retroactive election to avoid self-employment taxes for the year.
Although there is no liability protection, the single-member LLC is ideal for many entrepreneurs. Customers and vendors often take an LLC more seriously. The cost to start a single-member LLC is less than an S corporation.
Along with the basic level of liability protection provided by incorporation in which your personal property and assets cannot be seized during a debt settlement, the LLC provides you with an additional level of protection. This prevents your personal creditors from taking any of your business assets to deal with your personal creditors.
Single-member LLCs are great to start within many businesses, such as a new rental property. As you increase your number of rentals and expand into other states, you can set up a multi-member LLC very easily.
When to Choose a Single-Member LLC vs Multi-Member LLC
Choosing between a single member LLC and multi member LLC depends on your long-term vision and whether you plan to work alone or with partners.
You may want a single-member LLC if:
- You are launching a solo venture with no partners.
- You want to maintain full decision-making control.
- You prefer a simple tax structure (i.e., no separate business tax return).
- You want to easily convert to a multi-member LLC later if your business expands.
You may want a multi-member LLC if:
- You are starting a business with one or more co-owners.
- You need to raise capital from investors or partners.
- You want to share business responsibilities and risk.
- You desire stronger liability protection through multi-member status.
Disadvantages of a Single-Member LLC
Although there is some additional paperwork, LLCs are less formal that incorporation. Most states require LLCs to file annual reports, unlike sole proprietorships. If the LLC closes down, members will need to notify the state that the business is dissolved.
A disadvantage of an LLC over sole proprietorships is the amount of paperwork involved. You will also have continued maintenance at both state and federal levels.
State laws will give more protection to multiple-member LLCs. Currently, 18 states do not allow plaintiffs from accessing a property in an LLC to settle personal obligations.
To remain protected, you will need to maintain a formal operating agreement that states how your LLC will function. This keeps your liability protection intact. You should also set up a holding company in Wyoming, Nevada, or Delaware. This will force a plaintiff to fight his or her way through other states.
LLCs are rather informal, making it more difficult to get credit, raise money, and establish value for the business like you can for a corporation.
Converting Between Single-Member and Multi-Member LLCs
As your business grows, you might want to transition from a single-member LLC to a multi-member LLC—or vice versa. Fortunately, LLCs are flexible structures.
To convert from SMLLC to MMLLC:
- Add a new member and update your operating agreement.
- Notify your state’s business registration agency, if required.
- Apply for a new EIN from the IRS if ownership structure changes significantly.
To convert from MMLLC to SMLLC:
- Buy out or remove members per the terms in the operating agreement.
- Update state records to reflect the change.
- Amend tax status with the IRS, including potentially applying for a new EIN.
Operating Agreements: Why They Matter for Both LLC Types
Regardless of whether you form a single-member or multi-member LLC, an operating agreement is critical. This internal document outlines how the business operates, how profits are distributed, and how disputes are resolved.
For single-member LLCs, an operating agreement helps:
- Reinforce the LLC’s separation from the owner for liability protection.
- Clarify succession plans or what happens if the owner becomes incapacitated.
- Show legitimacy to banks and investors.
For multi-member LLCs, it is essential to define:
- Member roles and responsibilities.
- Voting rights and decision-making processes.
- Profit and loss distribution.
- Procedures for adding or removing members.
