The Iowa Business Council (IBC) on Monday announced that the Iowa Department of Revenue won the fourth annual Iowa Partners in Efficiency Award. The department's director, Courtney Kay-Decker, accepted the award from Gov. Terry Branstad on behalf of the state agency, which administers tax law and regulations in Iowa. The agency received the award for its efforts in developing a computer application that streamlined its process for applying accounts receivable adjustments, reducing delays by 97 percent and saving more than $200,000 in staff time annually. "Regulatory functions must perform as efficiently as possible if Iowa business is to compete effectively," IBC Executive Director Elliott Smith said in a release.
