On March 27, 2020, President Donald Trump signed Public Law 116-136, the Coronavirus Aid, Relief, and Economic Security (CARES) Act of 2020. The CARES Act includes a number of federal tax changes, and several are retroactive to tax years 2018 and 2019. Iowa has not conformed with any of these federal tax changes to the extent they apply to a tax year beginning prior to January 1, 2020. Iowa generally conforms with these federal tax changes to the extent they affect Iowa income taxes for tax years beginning on or after January 1, 2020. This guidance focuses primarily on Iowa’s nonconformity with this federal law for tax years 2018 or 2019, but it also includes explanations of certain other provisions and their impact on Iowa income taxes for tax years beginning on or after January 1, 2020 that may be of interest to taxpayers.

Iowa’s conformity with the federal limitations on business interest expense deductions imposed by Internal Revenue Code (IRC) section 163(j) varies depending on the year. For tax years beginning on or after Jan 1, 2019, and before January 1, 2020, Iowa conformed with the federal limitation. At this time Iowa does not conform to the federal limitation for tax years beginning on or after January 1, 2020. Due to these differences in conformity, some taxpayers will need to make certain adjustments to their federal business interest expense deduction to calculate the correct Iowa deduction amount for a given year.
This guidance was updated on 05/03/2021 to describe required adjustments and reporting procedures in tax years beginning on or after January 1, 2019 and before January 1, 2020, for partnerships and their partners that had business interest expense that was disallowed as a deduction for federal purposes under section 163(j) of the Internal Revenue Code in tax year 2018, but that was allowed as a deduction for Iowa purposes in tax year 2018 because of nonconformity. See Business Interest Expense Deduction for more information about adjustments to the business interest expense deduction required for tax years beginning on or after January 1, 2020.

On June 29, 2020 Governor Reynolds signed into law House File 2641.

At the time of a taxable purchase, Iowa state sales/use tax is collected by the retailer from the buyer. Unlike tangible personal property, which is subject to sales/use tax unless specifically exempted by Iowa law, services are subject to sales/use tax only when specified by Iowa law. Iowa sales tax is due when the first use of a taxable service occurs, or potentially could occur. The Iowa use tax complements the Iowa state sales tax. Generally, when a taxable service is purchased or obtained outside of Iowa for use in Iowa, it is subject to Iowa use tax.
