DES MOINES, Iowa (AP) — Iowa has granted tax deadlines in two southern Iowa counties hit hard by storms over the weekend. The Iowa Department of Revenue has granted extensions for affected taxpayers in Fremont and Union counties, where tornadoes struck in Thurman and Creston on Saturday. Gov. Terry Branstad has issued disaster areas for both counties. Officials say taxpayers whose principal business or home was affected by the storms will have until June 30 to file quarterly sales and use tax and withholding returns for the first quarter. Affected taxpayers also will have until June 30 to file their 2011 Iowa income taxes, which are normally due on April 30. The department says penalties and interest will be waived.
