We are committed to providing thorough and accurate information to support state government, inform Iowa’s citizens and allow our decision-makers to determine knowledgeable choices for Iowa. Revenue provides the foundation for the programs that make Iowa a better place to live, work and raise a family. Revenue touches nearly all aspects of everyday life through the state agencies and programs that benefit us all.
