If you need to change or amend an accepted New Mexico State Income Tax Return for the current or previous Tax Year, you need to complete Form PIT-X for the appropriate Tax Year. Form PIT-X is a Form used for the Tax Amendment. 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 New Mexico Tax Agency, thus you should file a New Mexico Amendment within one year.
