If you need to change or amend an accepted North Dakota State Income Tax Return for the current or previous Tax Year, you need to complete Form ND-1. Form ND-1 is the Form used for the Tax Amendment. You can prepare a 2020 North Dakota Tax Amendment on, 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 North Dakota Tax Agency, thus you should file a North Dakota Amendment within one year.
