What Is an LLC Amendment?
An LLC amendment is a formal filing that updates your LLC's Articles of Organization (or Certificate of Formation) on file with the Texas Secretary of State. It is required whenever a change affects information that was originally included in your formation documents.
Not all changes to your business require a state amendment — only changes to information registered with the state. Internal changes (like updating your operating agreement) are handled privately without filing with the Texas Secretary of State.
LLC Attorney offers free amendments within the first 90 days of formation for clients who need to correct or update their filing. After that window, amendment support is available at a flat rate.
When Do You Need to File an Amendment in Texas?
You must file a Certificate of Amendment with the Texas Secretary of State when changing any information that appears in your original formation documents. Common triggers include:
- LLC name
- Registered agent name and address
- Management structure (member-managed vs. manager-managed)
- Principal office address
- Business purpose
- Organizer information, member/manager names (if listed in original certificate), and authorized units of membership
Changes that do not require a state amendment include adding new clients, changing your business address if it's not your registered address, updating your banking relationships, or making internal changes to your operating agreement that don't affect your state filings.
