Amending the Homestead Credit Refund (for Homeowners) and Renter's Property Tax Refund Return

You may need to amend your original Form M1PR, Homestead Credit Refund (for Homeowners) and Renter Property Tax Refund, if your return has incorrect or outdated information affecting the amount of your refund.

To correct or change your return, you must file Form M1PRX, Amended Homestead Credit Refund (for Homeowners) and Renter Property Tax Refund. Common reasons to amend your return include any of the following:

  • You made a mistake when completing your original Form M1PR.
  • Your household income has changed.
  • You received a corrected or an additional Certificate of Rent Paid, or CRP (for renters).
  • You received a corrected Statement of Property Taxes Payable (for homeowners).
  • You received an abatement that reduced your property taxes (for homeowners).

When do I need to amend my return?

You must file Form M1PRX within 3½ years of the due date for the same year’s income tax return.

For example, you must file 2017 Form M1PRX within 3½ years of April 15, 2018 - that is, no later than Oct. 15, 2021. 

Do you charge or pay interest?

Yes. If your amended return reduces your refund, you must pay back the difference plus interest from the date you received your refund.

If your amended return increases your refund, you’ll receive the difference plus interest from one of the following dates, whichever is later:

  • 60 days after you filed the original return
  • Aug. 15 for renters or Sept. 30 for homeowners

To find our interest rates for recent years, see Interest Rates.

What if I found errors on my return but have not yet received my refund?

You may file Form M1PRX before we process your original return. Your refund may be delayed while we match up and process your original and amended returns.
