Provisions relating to taxes, interest, and depreciation on corporate property

(1) The bylaws of a cooperative housing corporation shall provide that no less than eighty percent of the gross income of the corporation in any taxable year shall be derived from payments from tenant-stockholders. For the purposes of this article, "tenant-stockholder" means an individual who is a stockholder in the corporation and whose stock is fully paid when measured by his proportionate share of the value of the corporation's equity in the property. (2) The bylaws shall further provide that each tenant-stockholder shall be credited with his proportionate payment of real estate taxes paid or incurred in any year on the buildings and other improvements owned or leased by the corporation in which the tenant-stockholder's living quarters are located, together with the land to which such improvements are appurtenant, and likewise with respect to interest paid or incurred by the corporation as well as depreciation on real and personal property which are proper deductions related to the said lands and improvements thereon for purposes of state and federal income taxation.
