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?
