How to Add a Member to an LLC

Learn how to add a member to an LLC, from amending the operating agreement to updating IRS classification and state filings.

When adding a member makes sense

Bringing a new member into your LLC can bring capital, skills, or a partner to share the workload. It can also change your taxes, your control, and your paperwork. Learning how to add a member to an LLC is mostly about updating documents, but the tax change is the part owners forget. If your LLC was a single-member company, adding a member changes its IRS classification from a disregarded entity to a partnership. That shift triggers new forms and new deadlines. Plan for it before you hand over the membership interest.

Step 1: Review the operating agreement

Your operating agreement likely says how new members are admitted. It may require a vote of existing members, a minimum capital contribution, or approval of the new member's ownership percentage. Follow those rules exactly. If the agreement is silent, state law usually requires unanimous consent of all current members. If you do not have an operating agreement at all, now is the time to write one. See our operating agreement guide for the key clauses.

Step 2: Amend the operating agreement

Adding a member means amending the operating agreement to list the new owner, their ownership percentage, and their capital contribution. The amendment should also update how profits and losses are shared and how voting works. Every member signs the amendment, including the new one. Keep the amended document with your LLC records. This is the document that proves who owns what, so it matters for banks, investors, and the IRS.

Step 3: Issue the new membership interest

The new member receives a membership interest, which is their ownership stake in the LLC. It can be issued in exchange for cash, property, or services. If the new member contributes services instead of money, the tax treatment is different and can be complicated. The LLC should issue a certificate or written acknowledgment of the interest and record the contribution in its books. Update the ownership schedule so every member's percentage is clear.

Step 4: Update your IRS classification

This is the step most owners miss. A single-member LLC is taxed as a disregarded entity, meaning the owner reports everything on Schedule C. The moment a second member joins, the IRS treats the LLC as a partnership, and the LLC must file Form 1065 every year and issue Schedule K-1 to each member. You do not file a special form to make the change; it happens automatically when ownership changes. If you want to be taxed as a corporation instead, you file Form 8832. Our tax guide explains the options.

Step 5: Update state and bank records

Some states require an updated filing when members change, and most ask for a current member list with the annual report. Update your bank accounts and signature cards so the new member can sign. Add the member to business licenses and insurance policies if needed. If the LLC has a registered agent or address change, file that too. Keeping every record current avoids problems at tax time and when you apply for credit.

Tax implications of adding a member

Adding a member can trigger tax consequences for the existing owners. If the new member pays more or less than the fair market value of their interest, the IRS may treat the difference as a gift or compensation. The LLC's tax year and accounting method may also change. Once the LLC becomes a partnership, each member receives a K-1 and pays tax on their share of income, whether or not it is distributed. A tax professional can model the impact before you commit.

Frequently Asked Questions

Does adding a member change my LLC's tax status?

Yes. A single-member LLC becomes a partnership for tax purposes when a second member joins. The LLC must then file Form 1065 and issue Schedule K-1 to each member.

Do I need to file anything with the state to add a member?

Usually not. Most states do not require a filing for membership changes, but you may need to update the member list with your annual report.

How much of the LLC should I give a new member?

It depends on what they contribute. Common practice is to base the percentage on the value of their capital contribution relative to the company's value. The operating agreement should define the split.

Can I add a member without an operating agreement?

Yes, but state default rules usually require unanimous consent of all current members. Without an agreement, the new member's rights and the profit split are unclear, so write one first.

What tax forms do I file after adding a member?

The LLC starts filing Form 1065 and issues Schedule K-1 to each member. If you choose corporate taxation instead, you file Form 8832 first.
