Minnesota Form M23 - Underpayment of Estimated Income Tax Instructions
Use Form M23 to claim a Minnesota property tax refund, income tax refund or credit for military service in a combat zone due a deceased taxpayer.
Use a separate Form M23 for each refund claim and for each tax year. Complete the name and address area and only one section - either for the property tax refund or the income tax refund/credit for military service in a combat zone.
If the decedent’s return has been filed, the department will issue the refund check to the decedent and mail it to the decedent’s address. If you are eligible to receive the decedent’s refund, complete Form M23 and mail it with the refund check to the address shown at the bottom of Form M23. If your claim is approved, the department will reissue the refund check in your name and mail it to your address.
If the decedent’s return has not been filed, complete Form M23 and include it, along with a copy of the decedent’s death certificate, when you file the decedent’s return. Mail the return, Form M23 and the death certificate to the address shown on the tax return.
To file the decedent’s return electronically, fax Form M23 and the decedent’s death certificate to 651-556-3124 at least one business day before the return is filed electronically.
Include the death certificate
You must include a copy of the decedent’s death certificate with your Form M23. Your claim cannot be processed without it.
Possible refunds for two years
If the decedent died after the end of his or her tax year (December 31, for most) and before filing Form M1PR, Property Tax Refund Return, Form M1, Individual Income Tax Return, or Form M99, Credit for Military Service in a Combat Zone for that year, there may be a refund available for a full tax year and one for the portion of the new tax year before the time of death. Complete a separate Form M23 for each refund claim and for each year.
Who can claim the refund?
Property tax refund
If the decedent died before filing Form M1PR OR died after filing but before receiving the refund check, the only persons eligible to claim the decedent’s property tax refund are the decedent’s surviving spouse or dependent. No one else, including the personal representative of the estate, can apply for the decedent’s property tax refund.
You are a dependent of the decedent if you could be claimed as a dependent on the decedent’s income tax return.
If the decedent did not file an income tax return and you are under age 19 (under age 24 if a full time student), or you did not have to file an income tax return for the years of the refund, check the M1PR instruction booklet to see if you are a dependent.
If the decedent died after receiving the refund but had not cashed the check, the refund is considered part of the estate.
Income tax refund or credit for military service in a combat zone
The personal representative of the decedent’s estate is entitled to claim income tax refund and credit for military service in a combat zone for the decedent. If no personal representative has been appointed to represent the estate, the persons eligible to claim the decedent’s income tax refund or combat zone credit are, from first to last:
- the decedent’s surviving spouse
- the decedent’s children
- the decedent’s grandchildren
- the decedent’s father and mother
- the decedent’s brothers and sisters
- the children of the decedent’s brothers and sisters
If more than one person can claim the refund
If more than one person can claim the refund or credit, all of the eligible persons must agree which one will receive it. That person must then have all the other eligible persons give their consent by signing the waiver form at the bottom of this page.
For example, if you are one of several children of the decedent, you must obtain the consent of the other children by having them sign the waiver form.
If taxes or debts are owed
If the decedent owed any Minnesota or federal taxes, criminal fines, a debt to a state agency, district court, qualifying hospital or public library, state law may require the department to apply the refund or credit to the amount owed (including penalty and interest on the taxes). The decedent’s Social Security number will be used to identify him or her as the correct debtor. If the debt is less than the refund, you will receive the difference.
Use of information
All information you provide on Form M23 is private by state law and cannot be given to others without your consent, except to the Internal Revenue Service (IRS), to other states that guarantee its privacy by law, to Minnesota courts, and to other Minnesota state, county and local government agencies. The Social Security numbers are required under M.S. 289A.12, subd. 13.
Information not required
Information requested on Form M23 is required by law to determine if you are eligible to receive the decedent’s refund. The only information you are not required to provide is your telephone number. However, we ask that you provide it in case we have to contact you. If you do not provide the required information, the department will send Form M23 back to you.
