How to Start a Series LLC In Texas

A series LLC in Texas is a special type of LLC that provides specific liability and tax benefits to its owners and members. The series LLC consists of a master LLC and one or more individual series that branch off from it.

Starting your own Series LLC in Texas doesn’t have to be difficult. Our step-by-step guide makes it simple!

  1. Name Your Series LLC
  2. Choose a Registered Agent
  3. File the Certificate of Formation
  4. Create a Series LLC Operating Agreement
  5. Obtain an EIN

Step 1: Name Your Texas Series LLC

1. Series LLC naming rules vary from state to state. In Texas, you are only required to follow traditional LLC naming laws when naming your series LLC. You must also file the assumed name certificate for each child series.

Follow the required Texas LLC Naming Rules:

  • Your name must include the phrase “limited liability company,” or one of its abbreviations (LLC or L.L.C.).
  • Your name cannot include words that could confuse your LLC with a government agency.
  • Restricted words (e.g. Bank, Attorney, University) may require additional paperwork and a licensed individual, such as a doctor or lawyer, to be part of your LLC.

For a complete list of naming rules in Texas, you can read the Secretary of State's guidelines.

2. Consider these general tips for making your series’ names more recognizable, uniform, and clear:

  • Use the word “protected series” within the name of each company.
  • Name the parent LLC in a way that distinguishes it from the child series.
  • Include the full name of the parent LLC in the name of each child series.
  • The name of the child series should include the name of the assets it holds. This creates a clearer asset picture to the public and creditors.

Example of a series LLC naming system that uses both the Texas requirements and general tips:

My Holdings Co., LLC, a series LLC

123 Main Street, LLC, an individual protected series of My Holdings Co., LLC, a series LLC

123 Division Street, LLC, an individual protected series of My Holdings Co., LLC, a series LLC

3. Is the name available in Texas? Make sure the name you want isn't already taken by doing a name search on the Texas Comptroller of Public Accounts website.

4. Is your business name available as a URL? We recommend that you check to see if your business name is available as a web domain. Even if you don't plan to make a business website today, you may want to buy the URL in order to prevent others from acquiring it.


Use a DBA, also called an assumed name in Texas, for the child series if the name is too long for good business branding.

Step 2: Choose a Texas Series LLC Registered Agent

You are required to nominate a Registered Agent for your Texas series LLC. The Registered Agent for the parent LLC will need to be the same for each child series.

What is a Registered Agent? A registered agent is a person or business that agrees to send and receive legal papers on behalf of your LLC. Such papers include service of process of legal action (if you are sued) and state filings.

Who can be a Registered Agent? A registered agent must be a resident of Texas or a corporation authorized to transact business in Texas. You may elect an individual within the company including yourself.

In Texas, a Registered Agent must consent to appointment in written or electronic form.

The statement of consent should include:

  1. The name of your series LLC and all child series
  2. An express statement that the person designated consents to serve as the series LLC’s registered agent
  3. The name of the person designated as registered agent
  4. The signature of the registered agent
  5. The date of execution

The consent statement does not have to be filed with the Secretary of State. For in-depth information on this requirement, as well as a fillable consent form, view the Acceptance of Consent Form 401-A.

Recommended: Northwest provides registered agent services for series LLCs. A subscription will need to be purchased for each LLC in the series ($125/year/LLC).

Step 3: File the Certificate of Formation

To register your series LLC, you will need to file the Certificate of Formation with the Secretary of State. This can be done online or by mail.

The key to creating a protected series LLC in Texas is drafting a legally correct Certificate of Formation and Operating Agreement.

The Texas Secretary of State has a “supplemental provisions/information” box on its Certificate of Formation form for your series LLC information. You or your attorney can also include an addendum if extra space is needed.

We recommend working with an Attorney to help create your Certificate of Formation.

The cost of filing the Certificate of Formation for the master LLC is $300. There is no additional cost for the child series.


To add additional child series or convert a traditional LLC into a series LLC, you must file a certificate of amendment to the articles of formation. Remember to also file an assumed name certificate for each new child series.

We recommend working with an Attorney to help you complete your series LLC Operating Agreement.

Step 4: Create a Series LLC Operating Agreement

An operating agreement is required when forming a series LLC in Texas. The operating agreement doesn’t have to be filed with the state.

What is an operating agreement? An operating agreement is a legal document outlining the ownership and operating procedures of an LLC.

Why are operating agreements important? The operating agreement is important for a Texas series LLC because it creates the protection between the child series and parent LLC. The operating agreement outlines the liability limitations (asset protection) of the child series.

The series LLC operating agreement should be written by, or with the advice of, an attorney.


New child series can be added to the series LLC by amending your operating agreement. Remember to also file a certificate of amendment to the certificate of formation and an assumed name certificate for each new child series. 

Step 5: Obtain an EIN

What is an EIN? The Employer Identification Number (EIN), or Federal Tax Identification Number, is used to identify a business entity. Each of the child series in your series LLC will require an EIN.

Why do I need an EIN? An EIN is required for the following:

  • To open a business bank account for the company
  • For Federal and State tax purposes
  • To hire employees for the company

How do I create an EIN for my series LLC? The IRS doesn’t have specific guidelines for creating an EIN for the child series of a series LLC. Experts suggest using the name of your series LLC combined with the child series name for each additional EIN.

 Example Series LLC EIN

Series LLC Name: My Holdings Co., LLC, a series LLC

EIN entry: My Holdings Co LLC a series LLC

Child Series Name: 123 Main St., LLC, an individual protected series of My Holdings Co., LLC, a series

EIN Entry: 123 Main St LLC an individual protected series of My Holdings Co LLC a series

Key Steps After Forming a Series LLC

Now that you have formed your Texas series LLC, these are the next steps you will need to take to move your business forward.

Open a Business Banking Account

A dedicated business banking account is required for each child series of a series LLC. Without dedicated accounts, the child series are NOT protected from liabilities incurred by the other child series or the parent LLC.

Set Up Accounting

Accounting and record keeping for the series LLC MUST be clear, concise, and separate. Without careful record keeping, your series might not be protected. Separate record keeping helps ensure the courts will never allow a creditor or plaintiff to pierce the corporate veil.

Accounting for your series LLC should be handled by a professional accountant or firm that is familiar with the series LLC.

Recommended: Use an accounting service to help with managing your Texas series LLC.


Expenses are sometimes shared across the series. For example, the series might share office space. Shared costs like rent can be spread out between the child series but it must be done in a logical way that will be defensible in court.

Register Your Series LLC for Texas State Tax

We recommend consulting a tax professional for help in tax planning and filing for your series LLC.

Maintain your LLC

File Your LLC Annual Report

Texas requires LLCs to file an annual report along with their Franchise Tax. The annual report form can be submitted through the Texas Comptroller of Public Accounts website. You will need to create an online account to complete the filing process.

The annual report will be filed by the parent LLC on behalf of all of the entities in your series LLC. Your franchise tax will be based on this information too.

File Your Annual Report

File Online with the State of Texas


Filing Fee: Free

Tax Calculation: LLCs with annualized revenue below $1,130,000 do not pay any tax, but must file a “no tax due report.” LLCs with annualized revenue greater than $1,130,000 pay a graduated tax that is calculated based on a complex formula.

Due Date: Due by May 15 each year. Reports do not need to be filed in the same year that an LLC is formed. 

Late Filings: Texas charges a $50 penalty for failure to file on time (whether or not you have tax due). Additionally, a late tax payment is subject to a 5% penalty fee, which increases to 10% if you pay after 30 days

Recommendation: The Texas Annual Report and Franchise Tax are complex, visit the Texas Comptroller website for more information.

Report LLC Income

Reporting income for your series LLC is best handled by an accountant who is familiar with series LLC tax code.

Avoid Dissolution

Series LLCs may face fines and even automatic dissolution when they miss one or more state filings. When this happens, LLC owners risk loss of limited liability protection. A quality registered agent service can help prevent this outcome by notifying you of upcoming filing deadlines, and even submitting reports on your behalf for an additional fee.

Recommended: Northwest offers a reliable registered agent service and excellent customer support.

Obtain a Certificate of Good Standing

A Certificate of Good Standing, known in Texas as a Certificate of Status, verifies that your series LLC was legally formed and has been properly maintained. Several instances where you might need to get one include:

  • Seeking funding from banks or other lenders
  • Forming your business as a foreign LLC in another state
  • Obtaining or renewing specific business licenses or permits

Dissolve Your Texas LLC

If at any point you no longer wish to conduct business with your LLC, it is important to officially dissolve it. Failure to do so in a timely fashion can result in tax liabilities and penalties, or even legal trouble. To dissolve your LLC, there are two broad steps:

  • Close your business tax accounts
  • File the Articles of Dissolution

Closing a child series will not dissolve the parent LLC. Dissolving the parent LLC will dissolve all of the child series under it.
