If you are talking about a non-profit, then what the company would need to do is comply with the non-profit corporations law of the state, which in this case would be Texas. The laws pertain primarily to what the company does with its profits, but also relate to ownership.

If you in fact mean a charitable organization, it will depend upon what type of organization we're talking about and its actual activities. Many museums, for example, are operated as charitable organizations but they're well-known for their gift shops.
