(a) In this section, “tiered partnership arrangement” means an ownership structure in which any of the interests in one taxable entity treated as a partnership or an S corporation for federal income tax purposes (a “lower tier entity”) are owned by one or more other taxable entities (an “upper tier entity”). A tiered partnership arrangement may have two or more tiers.
(b) In addition to the tax it is required to pay under this chapter on its own taxable margin, a taxable entity that is an upper tier entity may include, for purposes of calculating its own taxable margin, the total revenue of a lower tier entity if the lower tier entity submits a report to the comptroller showing the amount of total revenue that each upper tier entity that owns it should include within the upper tier entity’s own taxable margin calculation, according to the ownership interest of the upper tier entity.

(c) This section does not apply to that percentage of the total revenue attributable to an upper tier entity by a lower tier entity if the upper tier entity is not subject to the tax under this chapter. In this case, the lower tier entity is liable for the tax on its taxable margin.
(d) § 171.002(d) does not apply to an upper tier entity if, before the attribution of any total revenue by a lower tier entity to an upper tier entity under this section, the lower tier entity does not meet the criteria of § 171.002(d)(1) or (d)(2).
(e) The comptroller shall adopt rules to administer this section.
