Setting Up a Single-Member Limited Liability Company in Texas

April 16, 2025 by Sandra Ighalo - Tax Attorney & Business Law Counsel

Before setting up a single-member LLC, the first thing you need to know is whether or not you actually need one in the first place. In this guide, we’ll look at why sole-member business owners need a single-member LLC, how it works, and how to get one.

Protecting Your Personal Assets When You’re In Business for Yourself

One of the main purposes of forming an LLC, single-member or not, is to protect your personal assets. The LLC is its own legal entity, which means your business assets and personal assets stay separate. In case of losses or liability, your personal finances aren’t on the line.

Forming an LLC can also help you avoid double taxation, since a single-member LLC is treated as a disregarded entity by default, meaning your business income passes through to your personal tax return rather than being taxed at a separate corporate rate.

What Is an LLC in Texas, and Why Do Business Owners Choose This Structure?

If you’ve formed or are planning to form a single-member LLC in Texas, you’ve probably run into one question over and over: do you actually need an operating agreement? The short answer is that Texas law doesn’t require one — but that doesn’t mean you should skip it.

Why LLC Operating Agreements Matter

A limited liability company, or LLC, blends the simplicity of a sole proprietorship with the liability protection of a corporation. You report your business income on your personal tax returns rather than paying a separate corporate tax.

It also shields you from personal responsibility for the debts of the business. So, if a creditor comes after the company, your exposure is generally limited to what you’ve invested in the business itself, not your personal home, savings, or other assets.

Is an Operating Agreement Legally Required in Texas?

The answer is no. You’re not legally required to have an operating agreement as a sole business owner in Texas. However, you need a Certificate of Formation to show that your business is recognized under the law and can run legally.

But here’s the thing: the fact that you’re not “legally required” to have a registered LLC to run your business doesn’t mean it’s not necessary.”

A Texas operating agreement is an internal document that governs how your LLC actually runs. Without one, your business defaults to the general provisions of the Texas Business Organizations Code, which weren’t written with your specific business in mind and may not favor you.

Should a Single-Member LLC Have an Operating Agreement?

Yes, you should. A common misconception is that you only need an operating agreement when you have a partner or more than one to divide profits and resolve conflicts.

Even as the sole owner, having an LLC significantly benefits you. Here’s how:

  • It Reinforces Your Liability Protection: When you have an operating agreement, it shows that your business is its own entity and shields your personal assets from liability even though you’re the only member.
  • It Clarifies How the Business Operates Without You: In case of future circumstances that leave you unable to run your business, whether you want to sell, or you need additional hands, e.g., a partner, to make things run smoother. The operating agreement lays out how ownership, management, and succession would work.
  • Banks and Lenders Often Ask for It: Even though you can run your business without an operating agreement, many financial institutions want to see one before opening a business account with them or extending credit.

What Should a Texas Single-Member LLC Operating Agreement Include?

Here’s everything you need to cover in your LLC:

  • The LLC’s name, principal address, and registered agent
  • The purpose of the business
  • Ownership structure and the member’s capital contribution
  • How profits, losses, and distributions are handled
  • Management structure — whether  you plan to manage the LLC yourself or appoint a manager
  • Procedures for adding members, transferring ownership, or dissolving the business
  • What happens to the LLC if the member dies or becomes incapacitated

Don’t know where to start? Let’s have a chat to walkthrough the process and pick the best fit for your business.

How Do You Create a Single-Member LLC Operating Agreement in Texas?

There are different ways to go about forming your LLC. Here are some options:

  • Tailoring an Online Template: You can search for a free Texas LLC operating agreement template and edit it to fit your business goals and direction. However, these templates are generic and don’t have specific provisions for your business, assets, and long-term plans.
  • Work With an Experienced Business Law Attorney: This is the more reliable path, especially if you want more than documentation; you want a document that actually protects your assets. When working with an attorney, you can communicate your preferences and your plan, and they help you draft a valid, reliable agreement that would hold up if ever tested in court.

Does This Apply Outside Texas — What About Florida?

Every state handles this a little differently. In Florida, as in Texas, an operating agreement isn’t legally required for single-member LLCs, but it’s still recommended for the same reasons: liability protection, clarity, and credibility with banks and other institutions. If you operate in more than one state, it’s worth having an attorney confirm what each state expects.

A Quick Note on Other Texas Business Entities

Texas also allows for a series LLC. A series LLC is a structure that allows a single LLC to create separate “series” within it, each with its own assets, liabilities, and members.

If you’re weighing a series LLC against a traditional single-member LLC having an operational agreement becomes even more important, since it’s what defines the boundaries between series.

Whatever entity you choose, work together with your attorney to ensure you weigh your options properly, including the franchise tax and reporting obligations that apply to your specific business.

The Bottom Line

While it’s not compulsory to have an operating agreement as a single-member business owner, it’s a good idea to have one. You can opt for different types of LLCs depending on what’s best for your situation.

We hope this guide makes it easier to protect your personal assets while going into business. If you’d like to form an operating agreement that fits your current business situation while also protecting your assets and you against liability, book a consultation– we’ve been helping business owner put their best interest first for over a decade.

Operating Agreement FAQs

What is an operating agreement for an LLC in Texas?

It’s an internal document that sets out how the LLC is owned, managed, and operated. It isn’t filed with the state.

Does a Texas LLC Operating Agreement Need to Be Notarized?

No. Texas law doesn’t require an operating agreement to be notarized or witnessed. It simply needs to be signed by the member (or members) to be effective as a governing document for the LLC.

Do You Need to File Your Operating Agreement With the State?

No. Unlike the Certificate of Formation, which is filed with the Texas Secretary of State, the operating agreement stays with the business. It’s an internal document, though you should keep a signed copy in your business records and share it with your accountant, compliance officer, or attorney.
