How do I register my Series LLC in a state outside of Texas?

File your LLC in the same same, if available, noting that you'll need a registered agent and address within that state.

Every state handles foreign entity registration differently and the full list of requirements will be found on the Secretary of State website for the foreign state. In most states, you will need to pay a filing fee, ensure your entity name is not currently operating in that state, and provide a registered agent located within the state and a business address.
