Any person or business can form an LLC in Texas. You might have a sole proprietorship already or are about to open a business. In either of those situations, you can file for an LLC. Partnerships can also form as LLCs, and there is no limit on the number of partners. To submit a Texas LLC application, your business' principal business office must be located within the state of Texas. Follow the steps listed in this article to form and file your LLC application if you are in this situation. If your principal business office is located in another state, then you are what is called a foreign limited liability company. If you want to expand your business into Texas and operate within the state, then your foreign LLC must file an Application for Registration of a Foreign Limited Liability Company with the Texas Secretary of State.
