How to File a DBA in Texas in 2026: Step-by-Step Filing Guide

A DBA in Texas is commonly called an assumed name certificate. It lets a business operate under a name that is different from its legal name, which is useful when you want a brand name that is clearer, more marketable, or easier to remember.

For many Texas businesses, a DBA is a practical branding tool. It does not create a new legal entity, and it does not provide liability protection by itself. If you want a legal entity for liability separation and a DBA for a public-facing brand, many owners form an LLC first and then file one or more assumed name certificates as needed.

This guide explains who needs a DBA in Texas, where to file it, what information you need, and how to avoid common mistakes.

What a DBA Means in Texas

DBA stands for “doing business as,” but Texas law usually refers to this filing as an assumed name certificate.

A DBA can help you:

• Operate under a brand name instead of a legal name
• Separate your public-facing name from your entity name
• Use different names for different lines of business
• Present a more professional identity to customers, vendors, and banks

A DBA does not:

• Form a business entity
• Replace an LLC, corporation, or partnership filing
• Give you exclusive rights to the name
• Prevent someone else from using a similar or even identical assumed name

That last point matters. Texas filing offices accept assumed name certificates without determining name ownership rights. In other words, a DBA filing is a notice filing, not a trademark registration.

Who Needs a DBA in Texas?

Whether you need a DBA depends on how your business is organized and what name it uses in public.

Sole Proprietors

A sole proprietor generally needs a DBA if the business name is not the owner’s full legal name.

For example:

• No DBA needed: John Smith Landscaping
• DBA needed: Green Earth Landscaping

If you are operating only under your own full legal name, an assumed name filing is generally not required.

Partnerships

A general partnership or joint venture generally needs a DBA if it uses a trade name that does not include the surnames of all partners.

This filing is typically made at the county level, not with the Texas Secretary of State.

LLCs and Corporations

Texas LLCs, corporations, professional corporations, nonprofit corporations, limited partnerships, limited liability partnerships, professional associations, and other foreign filing entities generally file an assumed name certificate with the Texas Secretary of State when they use a name other than their legal name.

Example:

• Legal name: Sunrise Holdings LLC
• DBA: Austin Candle Co.

That business would typically file Form 503 with the Secretary of State if it is an entity required to file at the state level.

Where to File a DBA in Texas

This is where many owners get tripped up. Texas does not use a single filing path for every business type.

File With the County Clerk If You Are:

• A sole proprietor
• A general partnership
• A joint venture
• An estate
• A real estate investment trust
• Another business type that falls into the county-level filing category

County-level filers must file in each county where the business office is maintained, or if no Texas office is maintained, in each county where the business is conducted.

File With the Texas Secretary of State If You Are:

• A corporation
• An LLC
• A limited partnership
• A limited liability partnership
• A professional association
• A professional corporation
• Another foreign filing entity required to file at the state level

If your entity files with the Texas Secretary of State, you do not also need to file the same assumed name certificate with the county clerk.

Step-by-Step: How to File a DBA in Texas

1. Confirm That You Actually Need an Assumed Name

Start by comparing your legal name to the name you want to use in commerce.

If your public name is exactly the same as your legal name, a DBA is generally not required. If the public name is different, you may need to file.

For example:

• ABC, Inc. using ABC, Inc.: usually no DBA
• ABC, Inc. using ABC Coffee House: DBA may be required
• Jane A. Doe using Jane A. Doe: usually no DBA
• Jane A. Doe using Doe Consulting: DBA may be required

2. Choose a Name That Works for Your Brand

A good DBA should be easy to remember and should fit the business you actually operate.

Before filing, check for practical issues such as:

• Whether the name is already in use in your market
• Whether the name is too similar to a competitor
• Whether the name is suitable for websites, social handles, and signage
• Whether the name could be mistaken for another company

A DBA filing does not guarantee exclusive rights, so many owners also consider trademark research before investing heavily in a name.

3. Identify the Correct Filing Office

Next, determine whether you file at the county or state level.

This decision depends on your entity type and business structure. If you are a sole proprietor or partnership, you are usually dealing with the county clerk. If you formed an LLC or corporation, you are usually filing with the Secretary of State.

When in doubt, verify the filing path before submitting anything.

4. Complete the Correct Form

For Secretary of State filings, Texas uses Form 503, the Assumed Name Certificate.

The form asks for information such as:

• The assumed name
• The legal name of the entity
• The entity type
• The entity’s file number, if any
• The jurisdiction of formation
• The principal office address
• The counties where the name will be used
• The term of the filing

For county filings, the local clerk may have its own form and execution requirements.

5. Choose the Term of Use

Texas assumed name certificates include a stated term.

The term cannot exceed 10 years from the filing date. You can choose a shorter period, but if you keep using the name after the term expires, you must file a new certificate before the current one ends.

This is one of the easiest DBA details to miss, especially for businesses that file once and then forget about renewal timing.

6. Sign and Submit the Filing

For Secretary of State filings, the form can be submitted without an original notarized signature. Texas accepts faxed copies and photocopies of signed certificates for state filings.

The Secretary of State filing fee for Form 503 is $25, according to the current form instructions.

County fees vary by county, so check with the county clerk before filing.

7. Keep a Copy for Your Records

After filing, save the certificate with your core business records.

You may need it for:

• Opening a bank account
• Setting up vendor accounts
• Signing contracts under a trade name
• Internal compliance records
• Future renewals or abandonment filings

8. Renew Before It Expires

If you continue using the assumed name after the term ends, file a new assumed name certificate before expiration.

If your business information changes in a way that makes the filing materially misleading, you should file a new certificate within the required time frame rather than relying on outdated information.

9. File an Abandonment When You Stop Using the Name

If you stop using the assumed name, you can file a statement of abandonment.

This is especially useful when:

• You rebrand
• You close a line of business
• You switch to your legal entity name only
• You no longer want the trade name reflected in public records

Common Mistakes to Avoid

Filing the Wrong Way for Your Entity Type

One of the most common mistakes is filing at the county when the entity should file with the Secretary of State, or vice versa.

This matters because the filing office depends on the business structure.

Assuming a DBA Protects the Name

A DBA does not reserve or protect a name in the same way a trademark may. Another business may still file the same assumed name, and a similar name may create legal or market confusion.

Using the Exact Legal Name as a DBA

Texas does not allow an assumed name certificate for the exact legal name of the filing entity, because that is not actually an assumed name.

Letting the Filing Expire

If you are still using the name, track the expiration date and renew on time.

Ignoring Trademark Issues

A DBA filing and a trademark filing serve different purposes. If your brand is important, consider whether a trademark search and trademark application make sense in addition to the assumed name filing.

DBA vs. LLC: Which One Do You Need?

A DBA and an LLC solve different problems.

A DBA is for naming. An LLC is for forming a legal entity.

DBA Benefits

• Flexible branding
• Low filing friction
• Easy to use for a public-facing business name

LLC Benefits

• Separate legal entity
• Liability protection structure
• Cleaner ownership and operations framework
• Better foundation for growth and multiple brands

Many entrepreneurs choose both. They form an LLC for the legal structure, then file one or more DBAs for branding.

If you are starting from scratch and want to build a business the right way, Zenind helps founders form an LLC and stay organized with essential compliance support. A DBA can then sit on top of that entity as a brand name.

Practical Examples

Example 1: Freelancer

Maria provides design services as a sole proprietor.

• Legal name: Maria Lopez
• Business name: Maria Lopez Creative Studio

If she uses only her full legal name, a DBA may not be required. If she uses a different brand name, she likely needs an assumed name filing at the county level.

Example 2: Texas LLC

A Texas LLC named Prairie Peak Ventures LLC wants to operate a coffee shop called Prairie Peak Coffee.

The LLC would typically file an assumed name certificate with the Texas Secretary of State because the LLC is using a name other than its legal name.

Example 3: Partnership

Two partners run a landscaping business under a trade name.

If they are a general partnership using a name that does not include the surnames of all partners, they generally need a county-level assumed name filing.

Frequently Asked Questions

Does a DBA create a legal business?

No. A DBA is just a name registration. It does not create an LLC, corporation, or partnership.

How long does a Texas DBA last?

The assumed name filing term cannot exceed 10 years. If you want to keep using the name, renew before it expires.

Can two businesses have the same DBA in Texas?

Yes. Texas does not reject an assumed name filing just because a similar or identical name is already on file.

Do I need a DBA to open a business bank account?

Sometimes, yes. Banks may ask for the assumed name certificate if you are using a trade name.

Can I use my DBA on invoices and marketing materials?

Yes. Filing an assumed name generally allows you to advertise and do business under that name, subject to other laws and contract requirements.

Is a DBA the same as a trademark?

No. A DBA is a filing that tells the public what name you are using. A trademark is about protecting brand use in commerce.

Final Takeaway

If you are using a business name that is different from your legal name, a Texas DBA may be required. The key is to file it in the correct place, use the correct form, and keep track of the term so the filing does not lapse.

For sole proprietors and partnerships, that often means filing with the county clerk. For LLCs, corporations, and many other entity types, it usually means filing Form 503 with the Texas Secretary of State.

A DBA can help you brand your business, but it does not replace proper formation, compliance, or name protection. For founders who want a cleaner structure from day one, forming an LLC first and then adding a DBA is often the most practical path.
