The liquidation of a limited liability company is not taxable to a member to the extent of his tax basis in the company's interest. Limited liability companies are subject to the Texas franchise tax.
Most states have mechanisms for a foreign limited liability company to qualify to do business there.
If you plan to have your company do business outside the State of Texas, you should speak with an attorney in that state who is experienced with its laws and regulations concerning foreign limited liability companies.

If you neglect these steps, you may find that you have created a general partnership, exposing you and your colleagues to joint and several liability. Stick to your game plan, especially concerning tax treatment of your business.
