IDR Administrative Rules: Reorganization Update

During 2022, the Iowa Department of Revenue reorganized its administrative rules to reorganize the rules by related tax topics and to leave space in the Titles related to specific tax types for future expansion, as needed. Fifty-eight chapters have been editorially renumbered (see table). The changes were made primarily in an editorial filing effective November 2, 2022. Not all chapter numbers have changed, while some existing chapters were rescinded and other new chapters have been adopted.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 a reference table of chapters that have been editorially renumbered as well as those renumbered by the Department in recent rule-making documents.

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.
