This rulemaking amends the current rule under 86 Ill. Adm. Code 100.2430 to reflect the statutory changes enacted under Public Act 104-6 (the Act). The rulemaking provides examples that illustrate application of the statutory provisions.

The Act amended IITA sections 203(a)(2)(D-17), (a)(2)(D-18), (b)(2)(E-12), (b)(2)(E-13), (c)(2)(G-12), (c)(2)(G-13), (d)(2)(d-7), and (d)(2)(D-8). These statutory provisions require taxpayers, subject to certain exceptions, to make addition modifications in the computation of base income in amounts equal t0 the federal deductions allowed for interest or intangible expenses or costs paid to 80/20 affiliates. The Act made two changes to these provisions.

Second, the Act repeals two of the available exceptions to the addition modification for interest and one of the exceptions for intangible expenses.
