SEC. 21.22. RELIGIOUS, CHARITY, ETC.; PROCEDURE FOR ISSUANCE OF TAX EXEMPT REGISTRATION CERTIFICATES. (Amended by Ord. No. 149,522, Eff. 5/23/77.) (a) The provisions of this article shall not be construed to require the payment of any business tax to operate or carry on the functions of any charitable or religious institution, organization or association organized for charitable or religious purposes and conducted solely for such purposes, nor the payment of any business tax to engage in teaching, preaching or otherwise disseminating any religious tenets or the beliefs of any religion; nor shall any business tax be required to be paid by any religious or other charitable association, including fraternal, educational, civic, military, state, county and municipal organizations and associations, for the conducting or staging of any theatrical, art, or sporting exhibition or similar event, or any dance, concert, or lecture, when the net proceeds derived from any of the same are not used for the purpose of private gain to any individual but are used wholly for the benefit of such organization or for charitable or benevolent purposes, nor shall a business tax be required to be paid by any credit union corporation. Such persons are entitled to receive tax exempt registration certificates upon application for and qualification as provided in this section. (b) An independent contractor who for profit or gain undertakes to carry on any business or activity, for the conduct or operation of which a registration certificate and business tax is required by any section of this article, shall not be exempted from the registration and tax requirements of this Article because of the fact that the independent contractor has paid or agreed to pay or turn over to any charitable institution or organization a portion of the receipts of the business or activity as a reward or recompense for the sponsorship of the business or activity, or for any other reason, and such a contractor shall not be deemed to be acting for purposes entitling the contractor to a tax exempt registration certificate. (c) 1. The Director of Finance shall, upon application, issue a tax exempt registration certificate to any credit union corporation upon being furnished with satisfactory evidence of its incorporation and operation as such. 2.
