Pros and Cons of Adding a Partner to an LLC
The process of adding a partner doesn't have to be complicated. Like any undertaking, there are a few things to consider and a few procedures to follow.
- One thing that makes an LLC so attractive is that it protects owners from personal liability.
- It's imperative that the structure of the LLC includes a formal set of procedures and thorough recordkeeping to maintain continued protection and to avoid any disputes that may arise among the LLC's owners.
- Adding a new partner can have both positive and negative effects.
- Adding a new member can impact the percentage of profits distributed to the original owners.
- The new owner adds another person with an opinion that will have direct input in decision making. If new owners have ownership interests, it may be difficult to remove them if their participation isn't beneficial to the LLC.
- When a single-member LLC adds a partner, the option to file taxes as a sole proprietor is no longer an option. Instead, the LLC will have to file taxes as a corporation or a partnership.
- On the plus side, filing as a partnership allows other options for making tax decisions not available to a single-member entity.
- With a partnership, the LLC formation earnings go directly to the members who, in turn, pay income tax on their shares. Earnings are "passed through" from the business to the members.
- A new partner is not legally bound to contribute financially, but this usually means he or she is not allowed any voting rights on important matters concerning the LLC.
- When a new member is added, a decision needs to be made about what role he or she will have. Members must decide if the person will be an investor or a managing member. A managing member falls under a different set of tax rules than an investor.
- It is recommended that an attorney knowledgeable in business be consulted to explain the ramifications of adding a new member to the LLC.
- For multi-member LLCs, a meeting with the existing partners allows a discussion of adding a new member prior to voting.
- Once a decision is made on how to structure the role/responsibility of the new member, the operating agreement will need to have an amendment added to include the new member.
Common Reasons for Adding a Partner
Business owners often add partners to an LLC for strategic, financial, or operational reasons. Common motivations include:
- Expanding Capital: A new partner may bring additional funding to support growth or cover operational expenses.
- Complementary Skills: A partner with different expertise can enhance the LLC’s capabilities, such as marketing, finance, or technology.
- Spousal Partnership: In some cases, a spouse may be added for tax benefits or succession planning. However, this can affect the LLC’s tax classification and require updated filings.
- Rewarding Key Employees: Offering ownership to loyal or high-performing employees can incentivize continued contribution and loyalty.
Reviewing an Operating Agreement
While not required, it is highly recommended that an LLC create an operating agreement to outline the details of the operational structure and procedures.
- Information found in an operating agreement covers such areas as the roles and responsibilities of each member, allocation of profits and losses, how decisions will be made, and how changes to the business structure will be made.
- A notice of the operating agreement is provided to each existing member and as an amendment attached to the current copy of the agreement.
- By establishing an operating agreement and adhering to its rules and regulations, the LLC is seen as a well-organized independent entity.
- Be aware that by not having an operating agreement or not specifying how new members will be treated in your current operating agreement, the LLC must follow the procedure established in the limited liability laws of your state.
- Drafting an operating agreement is much easier than working out disputes without the benefit of established guidelines set up by the LLC members.
- Free operating agreement templates are available to guide you through the process to ensure what you create suits your business needs.
- You will need to decide on the specifics arrangements that will impact both the new partner and the existing partners.
- Discuss how the effects of each member's ownership percentages will be decided by the existing LLC members and the new member.
- The law of the state typically requires that a vote by existing members of the LLC must be unanimous to add a new member/partner unless the operating agreement provides a clause that a new member can be added with less than a unanimous consent.
Steps to Add a Partner to an LLC
Adding a partner to an LLC typically involves several legal and administrative steps:
-
Check the Operating Agreement
Confirm if it outlines a process for admitting new members and the voting requirements. If silent, state default rules apply. -
Get Member Approval
Most LLCs require a unanimous vote unless otherwise stated in the operating agreement. Document the decision in meeting minutes. -
Draft an Amendment
Update the operating agreement to reflect the new partner's rights, responsibilities, and ownership percentage. Include whether they’re a managing member or investor. -
File With the State (If Required)
Some states require LLCs to file an amendment to the Articles of Organization to reflect membership changes. -
Obtain a New EIN (If Necessary)
If the IRS considers your LLC a new entity due to the change (such as going from single-member to multi-member), you may need a new EIN. -
Update Financial and Legal Documents
Revise bank accounts, contracts, and tax filings to include the new partner’s details. -
Execute a Membership Purchase Agreement (Optional)
If the new member is buying into the LLC, this agreement outlines the payment and terms of ownership transfer.
Tax Considerations When Adding a Partner
Adding a partner can impact the LLC's tax classification and reporting obligations:
-
Change from Single-Member to Multi-Member LLC
This alters the IRS treatment from a disregarded entity to a partnership. You must begin filing Form 1065 and issue K-1s to each member. -
Spouse as Partner
If your spouse is added as a partner, the IRS may treat your LLC as a partnership unless you live in a community property state and elect to remain a disregarded entity. -
Capital Contributions
Contributions by the new partner (cash, property, or services) should be documented for accurate basis calculations and profit allocations. -
Consult a Tax Professional
Tax consequences can vary significantly based on the LLC’s structure and location. It’s advisable to seek professional guidance.
