This weekend will offer Iowans a chance to shop without the state’s 6% sales tax and the 1% local option sales tax in many cities. Iowa’s tax-free weekend always begins the first Friday in August. The holiday starts today and runs through Saturday August 3rd. Businesses opened on these days are required to participate. The tax-free weekend does not include Sunday. There are more than 100 different items on the tax-exempted list, according to the Iowa Department of Revenue. They range from formal clothing, to wedding apparel to adult diapers. Items that could still be taxed include backpacks, some sporting supplies and umbrellas. For a full list of Iowa’s tax-free items for the holiday go to the Iowa Department of Revenue’s website. Exemptions do not apply to the prices of an item selling for over $100
