On June 16, 2021, Governor Reynolds signed into law Senate File 619, which in part excludes from the Iowa income and franchise tax the receipt of certain qualifying COVID-19 grants issued by the Iowa Economic Development Authority, the Iowa Finance Authority, and the Iowa Department of Agriculture and Land Stewardship. This exclusion was previously only available for Iowa small business relief grants provided by the Iowa Economic Development Authority. The Department has updated guidance which describes this tax exclusion, identifies qualifying grants, and directs taxpayers on how to claim this exclusion on Iowa tax returns.

Income Tax, Coronavirus/COVID-19

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.
