In this article, I’ll provide first-hand advice from attorneys, legal advisors, and other experts on changing a single-member LLC to a multi-member.

  • You’ll also amend the operating agreement, update state and legal documents, and notify relevant agencies
  • Benefits of this process include increased capital, broader network, enhanced decision-making, and reduced individual liability

Steps of Changing a Single-Member LLC to Multi-Member LLC

Changing a single-member LLC to a multi-member LLC involves specific steps to ensure a smooth transition and compliance with legal requirements.

Follow these steps to navigate the process successfully:

1. Review the Current Operating Agreement

Begin by reviewing the existing operating agreement of the single-member LLC. Understand its provisions regarding admitting new members and the procedures for making changes. This step provides a foundation for the upcoming modifications.

Seek the consent of the current single member to admit new members and convert the LLC to a multiple-member structure.

This may involve discussions, negotiations, and obtaining written consent or agreement from a single member.

3. Identify and Bring in New Members

Identify potential new members who will join the LLC. Consider individuals or entities that align with the LLC's goals and objectives.

Add new members by executing membership interest transfer agreements and updating the ownership structure.

4. Amend the Operating Agreement

Prepare and execute an amendment to the operating agreement to reflect the changes in membership. Clearly outline the rights, responsibilities, and obligations of each member.

Ensure the amended operating agreement is legally binding and complies with relevant state laws.

File the necessary paperwork with the state agency responsible for business entities, such as the Secretary of State or State Corporation Commission.

Update the LLC's formation documents, such as the LLC Articles of Organization, to reflect the new multiple-member structure.

6. Notify Relevant Agencies and Authorities

Inform relevant agencies, such as the Internal Revenue Service (IRS), about the LLC structure change.

Update tax filings and forms to reflect the transition from a single-member to a multi-member LLC.

Consider consulting with a tax professional to ensure compliance with federal tax purposes.

7. Update Taxation and Financial Accounts

Revise the LLC's taxation and financial accounts to accommodate the new multi-member structure.

Update the Employer Identification Number (EIN)  with the IRS if necessary.

Open an LLC business bank account that reflects the new ownership structure and ensures separate financial management.

Single Member Vs. Multiple Member LLCs

Single-member LLCs offer simplicity and flexibility as they are easier to set up and manage. On the other hand, multiple-member LLCs allow for shared ownership and can provide more resources, expertise, and financial stability.

Here are a few phrases that can help distinguish a single-member from a multiple-member LLC:


In a single-member LLC, the owner reports business profits and losses on their personal income tax return (Form 1040) [1]. The LLC itself does not file a separate tax return.

In a multiple-member LLC, the LLC files a partnership tax return (Form 1065), and each member receives a Schedule K-1 reflecting their share of profits and losses [2]. LLC members then report this information on their individual tax returns.

Self-Employment Tax

The owner of a single-member LLC is responsible for paying self-employment taxes, which include both the employer and employee portions of Social Security and Medicare taxes.

Members of a multiple-member LLC also pay self-employment taxes on their distributive share of the LLC's profits.

Corporate Tax Status

A single-member LLC is classified as a disregarded business entity for tax purposes by default. This means that it is treated as a sole proprietorship.

On the other hand, multiple-member LLCs are classified as partnerships for tax purposes. However, a multi-member LLC can be taxed as a corporation by filing Form 8832 with the IRS [3].

Personal Asset Protection

While single-member LLCs provide some liability protection for the owner's personal assets, they may be more vulnerable to legal challenges that could pierce the corporate veil.

Multiple-member LLCs offer enhanced personal asset protection, as each member's personal assets are generally protected from business debts and liabilities.

Tax Consequences Of Adding A Member To An LLC

As with any business decision, there are tax consequences to adding a member to your multi-member LLC.

Unlike most property exchanges, contributing funds to a limited liability company in exchange for membership interest is not subject to tax gain or loss for the parties concerned.

That's because, for tax purposes, an LLC is considered a disregarded entity, so ownership changes do not result in federal taxes; however, when you do add a partner, you will be taxed as a partnership and must file a Schedule K-1 form.

This is how non-disregarded entity members will be taxed for their share of LLC net income or loss on Form 1065.

For example, a new member might cause the business to generate more taxable business income or trigger state income taxes on a new non-disregarded entity. Furthermore, certain states will require a separate filing for LLCs that have multiple LLC members.

In any case, it is essential to seek legal advice from a law firm or a tax professional before changing the makeup of your multi-member LLC.

What To Consider When Deciding Between A Single-Member LLC And A Multi-Member LLC

When deciding between a single-member LLC and a multi-member LLC, here are some factors to consider:

  • Control: Determine the level of control you desire over the company's decision-making process
  • Liability: Assess the level of personal liability protection needed for your business and personal assets
  • Resources: Consider the availability of financial resources, expertise, and support from additional members
  • Tax Implications: Evaluate the tax advantages and disadvantages associated with each type of LLC. A single-member LLC is simpler because it does not require a federal tax return unless it chooses to be taxed as a corporation, and one member has full control over the company [4]. 
  • Operating agreements: Multiple member LLCs typically require more complex LLC operating agreements to outline ownership rights, profit distribution, and decision-making processes
  • Ownership Structure: Decide whether you prefer to be the sole owner or share ownership with others in the business
  • Ease of formation and management: Single-member LLCs are generally simpler to set up and manage than multiple-member LLCs. Also, multi-member LLCs have no limit to the number of members they can add. They can be taxed as an S corp or a C corp.

Benefits of Changing a Single-Member LLC to a Multiple-Member LLC

Changing a single-member LLC to a multiple-member LLC can bring several benefits and opportunities.

Here are some key advantages:

  • Increased Capital Infusion: Adding a new member to an LLC brings in additional funds, enabling the company to finance growth, invest in assets, or expand operations
  • Broader Network and Business Connections: New members contribute their network and connections, opening doors to potential clients, partnerships, and opportunities for the LLC
  • Enhanced Decision-Making Capabilities: Additional perspectives and insights from new members lead to better-informed decisions and strategic planning for the LLC's success
  • Reduced Individual Liability: All members of an LLC enjoy limited liability protection, shielding personal assets from business debts and obligations
  • Potential for Increased Profitability and Growth: Adding new members can increase resources, expertise, and opportunities, potentially driving higher profits and facilitating the LLC's growth trajectory
  • Tax Flexibility: Multiple-member LLCs can be taxed as a partnership, providing potential tax advantages and flexibility in income distribution
  • Lower Self-Employment Tax: Adding members allows the LLC to allocate profits differently, potentially reducing overall self-employment tax burdens
  • Sharing of Responsibilities: Multiple members allow for the division of management duties, reducing the workload and promoting specialization
  • Diverse Skills and Resources: Additional members bring varied expertise, knowledge, and resources, strengthening the overall capabilities of the LLC
  • Enhanced Business Credibility: A multiple-member LLC may be perceived as more established and credible, potentially attracting more customers and business opportunities
  • Clear Operating Agreement: Multiple-member LLCs benefit from a detailed LLC operating agreement that outlines ownership rights, responsibilities, and decision-making processes
  • Potential Corporate Tax Status: Adding members can allow the LLC to elect corporate tax status, providing unique tax advantages and potential savings

When adding new members to the LLC, you are required to do the following:

  • Add the names of the new members to the Articles of Organization
  • Add details on how the membership interests will change in the organizational agreement
  • In case your company has been paying taxes as a sole proprietorship, you must close your accounting books and records when new members are acquired
  • You are required to file a short-year tax return for the current year if your LLC adds a new member during the tax year


Do I Need a New Employer Identification Number if I Change From a Single-Member to a Multi-Member LLC?

You will need a new Employer Identification Number if you change from single to multi-member LLC. But if the ownership percentages stay the same in the latter, you’ll not need an EIN.

Can You Convert an LLC to a Partnership?

You can convert an LLC to a partnership when you add a new member, but consequences are involved. A business partner will be taxed on their share of LLC net income or loss on Form 1065. You must also file a Schedule K-1 for each business partner.

Change From Single Member LLC To Multi-Member LLC

Transitioning your single-member LLC to a multi-member LLC offers several advantages.

Adding additional members can distribute the management responsibilities, share the workload, and potentially reduce the burden of personal liability. It may also aid in expanding your business's potential for growth and accessing additional capital resources.

Consider reviewing your operating agreement and obtaining consent from existing members or making necessary amendments.

To make this change, consult premium online legal services and tax professionals who can guide you through the process, ensuring compliance with relevant regulations and addressing any potential implications for taxes and ownership structure.
