With summer vacation winding down, parents are thinking about sending their children back to school. The state of Iowa wants to help them get ready. This year Iowa’s annual sales tax holiday is scheduled for Friday, August 1 and Saturday, August 2. The holiday removes the sales tax on a variety of back to school items such as clothes and footwear. The sale starts at 12:01 a.m., August 1 and runs through midnight, August 2.
