How to File a Texas LLC Amendment

Amending a Texas LLC Certificate of Formation

When you start your Texas LLC by filing a Certificate of Formation, you register information about your company with the Texas Secretary of State. As time goes by and your LLC grows, you may need to update that registered information on state records about the business. Most of those changes can be done by filing Form 424 – Certificate of Amendment.

When should I file a Texas Certificate of Amendment?

A Texas LLC files a Certificate of Amendment when its name is changed or its management structure needs to be updated. For example, file a Certificate of Amendment if your LLC goes from member-managed to manager-managed, or if individual member or manager information has changed. You can also file a Certificate of Amendment if you need to update any information that was provided (assuming you chose the option to add supplemental information or provisions on your LLC’s Certificate of Formation).

If you need to change your registered agent information, you can do it with a Certificate of Amendment, but unless you’re also updating other information at the same time, it’s much cheaper to simply file a $15 Form 401 – General Information (Change of Registered Agent/Office) instead.

Texas LLC Certificate of Amendment Form Information

No matter what you’re changing by amending your Certificate of Formation, you’ll need to include the following company information on your Certificate of Amendment form:

• Business name: Provide your LLC’s exact name.
• Entity type: Texas uses the same form for amendments for multiple types of businesses, so mark the box for “Limited Liability Company.”
• Entity number: Enter the 10-digit number assigned to your LLC by the Texas Secretary of State. If you don’t know your number, you can find it by using the Texas Taxable Entity Search.
• Date of formation: List the date your LLC was formed. If you don’t remember it, the exact date can be found on the Taxable Entity Search as well.
• Effective date: Choose when your amendments will go into effect. By default, this happens when the Texas Secretary of State files the certificate, but you can also choose a date up to 90 days after the date the Certificate of Amendment is signed. Or, you can list conditions that will cause the amendment to take effect at any point between signing and 90 days later. If you list conditions, your LLC will need to file a statement that those conditions were fulfilled with the Secretary of State within 90 days.

In addition, you will need to include a dated signature from a person who is authorized to act on behalf of your LLC.
