Through 2020 Iowa Acts, House File 2641, the General Assembly added the term “computer peripheral” to an existing sales tax exemption in Iowa Code section 423.3(47) and defined that term in Iowa Code section 423.1. This rule making adds that term to the Department’s rule implementing that exemption as applicable. The Department is also taking this opportunity to clean up a few other items in and related to those rules.

This rule implements the adjustments to income for Iowa individual and corporate income and franchise taxes for interest expense deductions, which are limited for federal income tax purposes but permitted in full for Iowa purposes for tax years beginning on or after January 1, 2020. The rule also covers adjustments that may be needed due to Iowa’s changing conformity with these federal limitations for tax years 2018 and 2019.

This rule making is intended to implement statutory changes to how fees, taxes, interest, and penalties are paid and deposited with the Department.
