Tex. Health and Safety Code § 221.033

(a) A health facility, including a leasehold estate in a health facility, that is owned by a development corporation and that, except for the purposes and nonprofit nature of the corporation, would be taxable to the corporation under Title 1, Tax Code, shall be assessed to the user of the health facility to the same extent and subject to the same exemptions from taxation as if the user owned the health facility. If there is more than one user of the health facility, the health facility shall be assessed to the users in proportion to the value of the rights of each user to occupy, operate, manage, or employ the health facility.

(b) The user of a health facility is considered the owner of the health facility for purposes of the application of:

(1) sales and use taxes in construction, sale, lease, or rental of the health facility; and

(2) other taxes levied or imposed by the state or a political subdivision of the state.

(c) A development corporation is engaged exclusively in performance of charitable functions and is exempt from taxation by the state, a municipality, or other political subdivision of the state. Bonds issued by a corporation under this chapter, a transfer of the bonds, interest on the bonds, and a profit from the sale or exchange of the bonds are exempt from taxation by the state, a municipality, or other political subdivision of the state.
