After a limited liability company (LLC) is up and running, the owner might wonder how to add a member to an LLC. As the company develops and expands, the owners might decide to add a new owner to diversify ownership, increase capital and resources, or reward a high-performing employee. This page explains how to add an owner to an LLC so that entrepreneurs can confidently make changes to their companies.
Yes. The limited liability company (LLC) combines the partnership structure’s flexibility with the personal liability protection offered by having a separate entity. The LLC’s operating agreement typically outlines the procedures for how to add a partner to an LLC. If an LLC still needs an operating agreement, it can be helpful to talk to a local business attorney. When a new member is added, the LLC might also need to file paperwork to change its tax status and Articles of Organization.
The owners of an LLC are called members. An LLC can have a single member or multiple members (i.e., a single-member LLC or a multi-member LLC). The members can share the management role as a member-managed LLC. They can also assign a manager to handle the day-to-day operations, creating a manager-managed LLC. The LLC operating agreement determines each member’s ownership stake and percentage of profits.
Adding a member to an LLC can give business owners access to new talent, cash, or relationships. However, it has drawbacks. The existing owners will want to consider the impact on their management structure and tax filing status.
Adding a partner to an LLC reduces the existing members’ percentage of profits. It can also complicate how management decisions are made. Removing a member is more complicated than firing an employee if things don’t work out.
Adding a new member may change the LLC’s tax classification. A single-member LLC is treated as a sole proprietorship for federal income tax purposes. When the LLC adds a new member, it becomes a multi-member LLC, which is taxed as a partnership. However, both these tax classifications have pass-through taxation, meaning that the business itself isn’t taxed on its profits, just the owners. The difference is that with a multi-member LLC, the owners will also need to file an informational business tax return, just as a partnership would.
If someone runs a single-member LLC and uses their Social Security number as their LLC’s tax identification number, they’d need to get an Employer Identification Number (EIN) when they add additional members. All LLCs with more than one owner must have an EIN from the IRS.
Can an LLC owner add members to their LLC? Yes, but they generally need to follow a specific process. Here are the main steps.
When forming the LLC, the original owners execute an operating agreement to govern the business’s internal operations. The operating agreement usually explains how to add a new member to an LLC, but most states don’t require them. If the LLC has an operating agreement in place, it can follow the process laid out there. If not, the LLC owners will need to consult their state’s laws to learn how to add a member to an LLC in that state.
Remember that a new member will change how the business is managed and reduce the existing members’ ownership. The existing members can vote on the new member’s capital contribution, percentage of ownership, and share of profits. Ideally, the operating agreement will provide guidance on any voting. Unless required by the operating agreement or state law, the owners can approve a distribution that isn’t proportionate to the size of ownership stakes.
No matter the size of the business, it’s a good idea to thoroughly vet the potential new member with a reference and background check.
After the members vote for the addition, they’ll need to update the LLC operating agreement to reflect the new ownership structure. The terms of the operating agreement may require a vote to amend it, too. Adding officers and subsequently updating the operating agreement may require a unanimous or majority vote. This is especially important for LLCs in states that require operating agreements by law, but it’s still helpful in states that don’t.
When the original owners started the LLC, they filed Articles of Organization (or a similarly named document) with the state government. Many states require the records to contain each member’s name and address. The LLC’s members should check their state’s requirements to see if they need to file Articles of Amendment to document the addition of the new member. Be sure to pay attention to any filing deadlines.
ZenBusiness’s amendment filing service can handle this step for busy entrepreneurs.
When someone runs an LLC as a single owner, they file taxes as a sole proprietorship, meaning they won’t need a separate tax return for the business. Adding an owner changes the way the owner will file taxes. The LLC will now be treated as a multi-member LLC and will be automatically treated as a partnership for federal tax purposes. LLCs with multiple members must file a separate federal information return for the LLC, Form 1065. Then each LLC member reports their share of the profits on Schedule K-1 and attaches it to their own personal federal tax return.
As stated earlier, single-member LLC owners who had been operating alone using their Social Security number as their federal tax identification number will need to apply for an EIN for the LLC.

A business owner should consult their operating agreement for the process. If the LLC doesn’t have an operating agreement, the owners will have to consult state law. Suppose someone is wondering how to add a business to an existing LLC. Most states allow businesses to hold ownership stakes in LLCs. Generally, business owners can follow the process explained above to add a business as a member if their state permits it.
It’s possible to edit an LLC’s members according to the procedure laid out in the operating agreement. Usually, adding or removing LLC members requires a unanimous vote of the existing members, an update to the operating agreement, and filing an amendment to the original LLC paperwork.
Yes, if the LLC operating agreement allows it.
Unless the Texas company agreement contains a different process, the existing members must unanimously approve a new member. The LLC must also file an amendment to the Certificate of Formation with the Texas Secretary of State. Learn more about how to amend a Texas LLC.
For a Florida LLC to add a new member, all existing members must consent unless the operating agreement says differently. The LLC must also file an amendment to its Articles of Organization with the Florida Department of State Corporate Division. Learn more about how to amend a Florida LLC.
