Administrative Rules: Renumbering Conversion Table

Starting in 2022, the Iowa Department of Revenue began reorganizing its administrative rules by related alignment and tax topics, including alcohol and lottery rules. Not all Iowa Administrative Code (IAC) chapter numbers have changed, while some existing chapters were rescinded and other new chapters have been adopted. The table below represents a comprehensive list of all current and recently changed chapters.

The Department plans to adopt a rule in the near future to establish this webpage as the primary resource of chapters that have been renumbered by the Department.

NOTE: Internal cross-references to other Department rules may not be updated to reflect the recent reorganization. In that case, internal links to those rules may not work. Please use the table below to help find the current rule.
