(a) A taxable item sold, leased, or rented to, or stored, used, or consumed by, any of the following organizations is exempted from the taxes imposed by this chapter:
(1) an organization created for religious, educational, or charitable purposes if no part of the net earnings of the organization benefits a private shareholder or individual and the items purchased, leased, or rented are related to the purpose of the organization;
(2) an organization qualifying for an exemption from federal income taxes under Section 501(c)(3), (4), (8), (10), or (19), Internal Revenue Code, if the item sold, leased, rented, stored, used, or consumed relates to the purpose of the exempted organization and the item is not used for the personal benefit of a private stockholder or individual;
(3) a nonprofit organization engaged exclusively in providing athletic competition among persons under 19 years old if no financial benefit goes to an individual or shareholder;
(4) a company, department, or association organized for the purpose of answering fire alarms and extinguishing fires or for the purpose of answering fire alarms, extinguishing fires, and providing emergency medical services, the members of which receive no compensation or only nominal compensation for their services rendered, if the taxable item is used exclusively by the company, department, or association; or
(5) a chamber of commerce or a convention and tourist promotional agency representing at least one Texas city or county if the chamber of commerce or the agency is not organized for profit and no part of its net earnings inures to a private shareholder or other individual.
(b) The sale of, or contracting for the sale of, concessions at an event conducted by an organization exempted under Subsection (a)(3) of this section does not prevent the application of the exemption to that organization.

(c) An organization that qualifies for an exemption under Subsection (a)(1) or (a)(2) of this section, and each bona fide chapter of the organization, may hold two tax-free sales or auctions under this subsection during a calendar year and each tax-free sale or auction may continue for one day only. The sale of a taxable item the sales price of which is $5,000 or less by a qualified organization or chapter of the organization at a tax-free sale or auction is exempted from the sales tax imposed by Subchapter C of this chapter, except that a taxable item manufactured by or donated to the qualified organization or chapter of the organization may be sold tax free regardless of the sales price to any purchaser other than the donor. The storage, use, or consumption of a taxable item that is acquired from a qualified organization or chapter of the organization at a tax-free sale or auction and that is exempted under this subsection from the taxes imposed by Subchapter C of this chapter is exempted from the use tax imposed by Subchapter D of this chapter until the item is resold or subsequently transferred.
(c-1) Notwithstanding Subsection (c), an organization that qualifies for an exemption under Subsection (a)(4) may hold 10 tax-free sales or auctions during a calendar year. Each tax-free sale or auction may continue for not more than 72 hours. The storage, use, or consumption of a taxable item that is acquired from a qualified organization at a tax-free sale or auction and that is exempted under this subsection from the taxes imposed by Subchapter C is exempted from the use tax imposed by Subchapter D until the item is resold or subsequently transferred. If an organization that qualifies for an exemption under Subsection (a)(4) jointly holds a tax-free sale or auction with one or more other exempt organizations, the tax-free sale or auction is considered to be one of the organization’s 10 tax-free sales or auctions authorized by this subsection during that calendar year.
(d) If two or more organizations jointly hold a tax-free sale or auction, each organization may hold one additional tax-free sale or auction during the calendar year in which the joint sale or auction is held. The employment of and payment of a reasonable fee to an auctioneer to conduct a tax-free auction does not disqualify an otherwise qualified organization from receiving the exemption provided by Subsection (c).
(e) A nonprofit hospital or hospital system that qualifies for an exemption under Subsection (a)(2) shall provide community benefits that include charity care and government-sponsored indigent health care as set forth in Subchapter D, Chapter 311, Health and Safety Code.
(f) For purposes of obtaining a refund of or claiming a credit for taxes paid under this chapter on the basis of an exemption under this section, an organization is not considered exempted from the taxes imposed by this chapter before the earlier of:
(1) the date the organization applied for the exemption with the comptroller; or
(2) the date of assessment of the organization’s tax liability by the comptroller as a result of an audit, as applicable.
