You must file an amended Minnesota return on Form M1X if any of these apply:

• You or your client discover an error on their Minnesota return
• The IRS made changes to your client?s federal return
• You amend your client?s federal return

What should I know about amending Minnesota returns?

• Each tax year has its own amended tax return form
• Generally, your clients must file amended returns within 3.5 years of the due date of the original return
• If your client filed as Married Filing Jointly, you cannot change the filing status to Married Filing Separately after the return?s due date
• If changes require an additional schedule or form, or if a schedule or form changes, attach it to the amended return
• If both the original and amended returns result in a refund, wait until your client gets their original refund before filing the amended return
• Review our Amending a Return in Special Circumstances page if your client is divorced or filing a protective claim
• Use Form M1PRX to file amended property tax refund returns for renters or homeowners
