Taxpayers provide confidential tax information to the Iowa Department of Revenue (IDR) in the form of individual income tax returns and other Iowa schedules, forms, and supporting documentation.
Your tax information is kept confidential by IDR, with a few exceptions as required by law. Most notably, information from your return may be made available to the Internal Revenue Service or to tax officials of another state for tax administration purposes.
Any IDR employee who discloses tax return information without legal authority is guilty of a serious misdemeanor, subject to a fine and any civil damages.
If you do not provide individual income returns and/or the necessary information to support the return, or if you provide fraudulent information, you may be charged penalties and interest and may be subject to criminal prosecution.
