To add a member to an LLC in Texas, start with your operating agreement: it controls how new owners come in. If the agreement is silent, Texas law requires unanimous consent from every current member. From there, you agree on the terms with the incoming member, amend the operating agreement, file a certificate of amendment with the Secretary of State only if the change touches information in your certificate of formation, and deal with the federal tax consequences, which are usually the most significant part of the whole exercise.
Start With Your Operating Agreement
Your operating agreement governs how members are admitted. Pull it out and look for the vote or written consent required, any restrictions on who can be a member, and any notice or meeting rules. If it spells out a process, follow it. The Texas Business Organizations Code gives company agreements broad authority over internal affairs, and members are bound by those terms whether they signed or not.1State of Texas. Texas Business Organizations Code Title 3 – Section 101-052
If the agreement says nothing about admitting members, the statutory default applies: every current member must approve or consent to the admission.2State of Texas. Texas Business Organizations Code Title 3 – Section 101-103 Unanimous consent surprises a lot of owners, especially in LLCs with several members where one might object. If unanimity is impractical, consider amending the operating agreement now to set a workable voting threshold before you need it.
Agree on the Terms of Admission
Negotiate the deal before you take any vote. The existing members and the new member need to agree on:
- Capital contribution: how much cash, property, or services the new member will contribute for their interest.
- Ownership percentage: the share the new member receives, and how the existing percentages adjust.
- Voting rights: whether the new member votes on all decisions or only some.
- Profit and loss sharing: how distributions are split, which doesn’t always mirror ownership percentages.
Once the terms are set, take the vote or collect the written consents your agreement or the statute requires. Document the approval in meeting minutes or a written consent resolution and keep it in your LLC records. Skip this and you have a dispute waiting to happen.
Amend the Operating Agreement
Update the operating agreement to reflect the new ownership. You can do a full amended-and-restated agreement or a shorter amendment that identifies the new member, their interest, their contribution, and any changes to management or profit-sharing. Every member, including the new one, signs.
Attorney fees for drafting or reviewing an amendment generally run $500 to $1,500 or more depending on complexity. A straightforward cash-for-percentage admission costs less than a deal involving property contributions, vesting, or a management restructure.
Give the new member copies of the amended operating agreement, the certificate of formation, prior amendments, and current financial statements. Starting them with full information heads off misunderstandings later.
File With the Texas Secretary of State Only If Required
Not every member addition triggers a state filing. You amend your certificate of formation only if the change affects information that is actually in that document. The usual triggers are switching between member-managed and manager-managed, or changing the name of a manager or member who was specifically named in the certificate.3Office of the Texas Secretary of State.

If nothing in the certificate of formation changes, no state filing is required. The operating agreement amendment handles it internally.
Handle the Federal Tax Consequences
Taxes are where adding a member gets complicated, and where owners most often get caught out.
Going From Single-Member to Multi-Member
A single-member LLC is a “disregarded entity” for federal income tax; all income and deductions flow onto your personal return. Add a second member and the IRS reclassifies the LLC as a partnership by default.8Internal Revenue Service. LLC Filing as a Corporation or Partnership That reclassification isn’t optional unless you affirmatively elect corporate treatment.
As a partnership, the LLC files Form 1065 every year, even with no income. The deadline is March 15, and each member gets a Schedule K-1 for their share of income, deductions, and credits.8Internal Revenue Service. LLC Filing as a Corporation or Partnership Late filing draws penalties of $255 per partner per month.
The switch from single-member to multi-member may also require a new Employer Identification Number, because the IRS can treat the reclassification as the creation of a new entity. Confirm your situation against the IRS’s guidance on when a new EIN is required.9Internal Revenue Service. When to Get a New EIN
Property Contributions
If the new member contributes property instead of cash, federal law is generally forgiving. Neither the LLC nor the contributing member recognizes gain or loss on a contribution of property in exchange for a partnership interest.10Office of the Law Revision Counsel. 26 USC 721 – Nonrecognition of Gain or Loss on Contribution The LLC takes the property at the contributing member’s original basis, and the contributing member’s basis in the new interest equals the property’s basis.
There are exceptions. The nonrecognition rule doesn’t apply if the LLC is treated as an investment company, separate rules cover foreign contributors, and property contributed subject to debt can trigger tax if the debt shifts to other members. Get tax advice before closing the contribution if any of these apply.
Electing Corporate Treatment
If the members prefer corporate tax over partnership tax, file Form 8832. The election can take effect up to 75 days before filing or up to 12 months after.11Internal Revenue Service. Form 8832, Entity Classification Election Missing that window means using late-election relief procedures, which add complexity. Most multi-member LLCs stay with the partnership default to avoid double taxation, but the S-corp or C-corp election can make sense depending on income and distribution patterns.
Update the Texas Franchise Tax Filing
Adding a member doesn’t change the LLC’s franchise tax obligation. The Texas Comptroller treats every LLC as a separate legal entity for franchise tax purposes regardless of federal classification, so a single-member LLC has always been a separate franchise tax filer. What does change is the ownership information the LLC reports. The Public Information Report or Ownership Information Report filed annually should reflect the new member on your next filing.12Texas Comptroller of Public Accounts. 2026 Franchise Tax Instructions
Notify Banks, Lenders, and Other Third Parties
With the legal and tax pieces in place, work through the administrative cleanup. Tell the bank about the membership change and update signature authority if the new member will have account access; some banks want a copy of the amended operating agreement or a resolution authorizing the new signer.
Contact lenders, landlords, insurance carriers, and licensing agencies that need to know. Loan agreements and commercial leases sometimes require prior written consent before admitting a new member, and skipping the notice can trigger a default. Review those contracts before finalizing the admission if you haven’t already.
Update internal records: member contact lists, the ownership ledger, and any membership certificates the LLC has issued. Give the new member access to the full set of operating documents, financial records, and the filed certificate of amendment if one was needed, so they can participate in governance from day one.
