How to File a Massachusetts State Tax Amendment

If you need to change or amend an accepted Massachusetts State Income Tax Return for the current or previous Tax Year you need to complete Form 1 (residents) or Form 1-NR/PY (nonresidents and part-year residents) for the appropriate Tax Year. For Tax Years 2016 and later, fill in the circle on the top of the form indicating that it's an amended return. If you're completing an amended return for 2015 or an earlier Tax Year, simply write "Amended return" on the top of your form. Forms 1 and 1-NR/PY are Forms used for the Tax Return and Tax Amendment. You can prepare a current tax year Massachusetts 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 Massachusetts Tax Agency, thus you should file a Massachusetts Amendment within one year.
