Iowa
“The Hawkeye State“

If you need to change or amend an accepted Iowa State Income Tax Return for the current or previous Tax Year you need to complete Form IA-1040X. Form IA-1040X is a Form used for the Tax Return and Tax Amendment. You can prepare a 2018 Iowa Tax Amendment on eFile.com, however you can not submit it electronically. In comparison, the IRS requires a different Form - Form 1040X -to amend an IRS return (do not use Form 1040 for an IRS Amendment).

The IRS might send you a notification to change an error on your Return, or you might have discovered an error. If you or the IRS amended or changed one of your IRS Tax Return(s), the IRS will report this to the Iowa Tax Agency, thus you should file a Iowa Tax Amendment within one year.
