amend Indiana taxes
Indiana
"The Hoosier State"

If you need to change or amend an accepted Indiana State Income Tax Return for the current or previous Tax Year, you need to complete Form IT-40X.  Form IT-40X is a Form used for the Tax Amendment. You can prepare a 2018 Indiana Tax Amendment on eFile.com, however you cannot 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 Indiana Tax Agency, thus you should file an Indiana Amendment within one year.
