How to File a Texas LLC Amendment with the Texas Secretary of State

A Texas LLC does not stay static forever. Business names change, ownership structures evolve, registered agents move, and company details get updated as the business grows. When that happens, the Texas Secretary of State needs to have accurate public records for your company.

For most Texas LLC updates, the main filing is Form 424, Certificate of Amendment. In some situations, a different filing is more efficient, such as a Certificate of Correction for errors or a Form 401 for a registered agent or office change only. Choosing the right filing matters because it can save time, money, and unnecessary follow-up with the state.

This guide explains when to file a Texas LLC amendment, what information to include, how to submit the form, how much it costs, and how to avoid common mistakes.

When should a Texas LLC file an amendment?

You should file an amendment when you need to change information that is already on record in your Certificate of Formation. Common reasons include:

• Changing the LLC name
• Switching from member-managed to manager-managed
• Updating member or manager information if it appears in the formation document
• Adding, altering, or deleting provisions in the Certificate of Formation
• Updating a registered agent or registered office when paired with other changes

If the only update is a change to the registered agent or registered office, Texas often allows a separate change filing that may be less expensive than an amendment. If the problem is an error in the original filing rather than a business change, a Certificate of Correction is usually the better option.

Amendment vs. correction vs. restatement

Texas business owners sometimes confuse these filings because they can all affect the company record.

Certificate of Amendment

Use this when your LLC is making a real change to the information on file, such as a name change, management change, or updated provisions.

Certificate of Correction

Use this when you need to fix a mistake in the original filing. This is for errors, not new business decisions.

Restated Certificate of Formation

A restatement rewrites the formation document in a single consolidated filing. It can be useful when many provisions are changing at once, but it is generally more expensive than a standard amendment.

What information goes on Form 424?

When filing a Texas LLC Certificate of Amendment, the form must identify your business and describe exactly what is changing. The filing typically includes:

• The exact legal name of the LLC
• The entity type as a limited liability company
• The Texas entity number
• The date the LLC was formed
• The amendment details
• The effective date of the change, if you want something other than the filing date
• A dated signature from an authorized person

If you do not know your entity number or formation date, you can usually find them through the Texas business search or your original formation records.

What can you change in an amendment?

A Texas Certificate of Amendment can be used for several types of updates.

1. Change the LLC name

If your business is rebranding or adopting a new legal name, the amendment should list the new LLC name exactly as you want it recorded.

Before filing, confirm that the new name is available and meets Texas naming rules. It is also wise to update banking, tax, licensing, and contract records after the state approves the change.

2. Update management structure

Texas LLCs may shift between member-managed and manager-managed structures. If that change is reflected in the Certificate of Formation, the amendment should clearly state the updated management arrangement.

3. Update member or manager information

If member or manager information appears in your formation document, and that information needs to be changed, the amendment should identify the affected provision and provide the revised text.

4. Add, alter, or delete provisions

The form allows additional changes beyond basic company details. You can:

• Add a new provision
• Alter an existing provision
• Delete a provision

If there is not enough room on the form, you can attach additional pages with the necessary language.

Effective date options

By default, an amendment becomes effective when the Texas Secretary of State files it. However, you may be able to choose a delayed effective date, subject to the form’s rules.

In some cases, you can also make the amendment effective on a future date or upon a stated condition. If you use a conditional effective date, make sure you understand any follow-up filing requirements so the state record remains accurate.

How to file a Texas LLC amendment

Texas LLC amendments can generally be filed in more than one way, depending on the filing type and your preferred process.

File online

Texas offers online filing options through its business filing systems. Online filing is often the fastest way to submit a name change or other amendment, especially if you want to avoid mailing delays.

File by mail

You can print the amendment form and mail it to the Texas Secretary of State. If you file by mail, include any required duplicate copies and a cover letter if you are requesting expedited handling.

File in person

Texas also accepts in-person submissions at the Secretary of State office in Austin. This can be helpful if you need direct delivery or want to avoid postal delays.

Texas amendment filing fee

The standard fee to file a Texas Certificate of Amendment is $150.

If you need faster processing, an expedited option may be available for an additional fee. Always verify the current filing instructions before submitting, since filing methods and fees can change.

How long does processing take?

Processing times depend on how the amendment is submitted and how busy the Secretary of State’s office is at the time of filing.

Typical timelines may vary for:

• Online filings
• Mailed paper filings
• Expedited paper filings
• Name change filings submitted through the state system

If your filing is time-sensitive, plan ahead and avoid waiting until the last minute to make a business-critical change.

Common mistakes to avoid

A Texas LLC amendment is straightforward when the filing is prepared carefully, but small errors can delay approval.

Filing the wrong document

Do not use an amendment when the issue is actually a correction or a registered agent change only.

Using the wrong business name or entity number

The state filing must match the LLC’s official record. A mismatch can slow processing.

Forgetting to include the exact amendment language

If you are changing a provision, the form should clearly show what is being added, altered, or deleted.

Missing the signature

The filing must be signed by someone authorized to act on behalf of the LLC.

Not updating related records

Once the amendment is approved, make sure the LLC’s bank accounts, contracts, tax records, licenses, and internal documents reflect the update.

Texas LLC amendment checklist

Use this checklist before filing:

• Confirm whether an amendment is the correct filing
• Gather the LLC’s exact legal name
• Confirm the Texas entity number
• Identify the original formation date
• Draft the precise amendment language
• Decide whether the change should be effective immediately or later
• Sign the form correctly
• Include duplicate copies or attachments if required
• Submit by the proper filing method
• Save the approved filing for your records

Why accurate filings matter

State records are part of your company’s legal identity. When your Texas LLC changes, the official record should change too. Clear and accurate filings help avoid confusion with banks, vendors, tax agencies, and customers.

Accurate records can also reduce problems when you need to prove who controls the company, where it is located, or what its legal name is at a given time.

Final thoughts

A Texas LLC amendment is the right tool when your business changes and the Certificate of Formation needs to be updated. The key is to choose the correct filing, prepare accurate amendment language, and submit it through the proper channel.

If your change is limited to a registered agent update, a correction, or a name change processed through a different state filing option, that may be more efficient than a standard amendment. Taking the time to file correctly helps your Texas LLC stay compliant and keeps your public record accurate.
