2023 Form M8X Instructions 

Before you     can   complete  Form  M8X,  you  will  need  the  M8  instructions  for  the  year  you  are  amending. 

Who Should File M8X? 
This form must be filed by S corporations to correct—or amend—an original Minnesota Form M8, S Corporation Return. If you are amending a 
return from a tax year other than the year listed at the top of this form, use the Form M8X for that year. 
Federal Return Adjustments. If the Internal Revenue Service (IRS) changes or audits your federal return or you amend your federal return, you 
have 180 days to file an amended Minnesota return. If you are filing Form M8X based on an IRS adjustment, check the box in the heading and 
attach to your Form M8X a complete copy of your amended federal return or the correction notice you received from the IRS. 
If you fail to report as required, a 10 percent penalty will be assessed on any additional tax. See line 19 instructions. 
Claim for Refund. Use Form M8X to make a claim for refund and report changes to your Minnesota liability. If you make a claim for a refund 
and we do not act on it within six months of the date filed, you may bring an action in the district court or the tax court. 

Pass-through Entity Tax and Nonresident Withholding
Overpayments of nonresident withholding are limited to the amount of the overpayment that was not deducted or withheld from the  
S corporation. Overpayment of the PTE tax are limited if the shareholder has claimed the pass-through entity tax credit on their return. 
The S corporation should provide enough information so the shareholders may file an accurate amended income tax return. This may include 
amended federal schedules K-1 and KS showing the change. The shareholders must amend their income tax return reflecting these changes to 
calculate a change in tax due. 

When to File 
File Form M8X only after you have filed your original return. You may file Form  M8X within 3½ years after the return was due or within one 
year from the date of an order assessing tax, whichever is later. If you filed your original return under an extension by the extended due date, you 
have up to 3½ years from the extended due date to file the amended return. 

Filing Reminders
The amended return must be signed by a principal officer of the corporation. 
If you pay someone to prepare your return, the preparer must sign and enter his or her PTIN number and daytime phone. 
Round amounts to the nearest dollar. Decrease any amount less than 50 cents and increase any amount that is 50 cents or more to the next 
higher dollar. 

Completing the Form
Enter the beginning and ending dates for the tax year you are amending at the top of the form. Enclose, on a separate sheet of paper, a detailed 
explanation of why the original return was incorrect. Providing this information will help us verify the amended amounts. Do not staple or tape 
any enclosures to your return.  
Estimated payments and refunds credited to subsequent years cannot be amended or changed after the original return is filed. 
Form AWC, Alternative Withholding Certificate, can only be filed with the original return. Any Forms AWC received after the filing of the 
original return will be denied. 
Apportionment Factors. Minnesota uses the single sales apportionment factor. 

Use of Information 
All information provided on this form is private, except for your Minnesota tax ID number, which is public. Private information cannot be given 
to others except as provided by state law. 
The identity and income information of the shareholders are required under state law so the department can determine the shareholder’s correct 
Minnesota taxable income and verify if the shareholder has filed a return and paid the tax. The Social Security number of the shareholders are 
required to be reported on Schedule KS under M.S. 289A.12, subd. 13. 
Lines 1–16  
Columns A, B and C 
Column A: Enter the amounts shown on your original return or as later adjusted by an amended return or audit report. 
Column B: Enter the dollar amount of each change as an increase or decrease for each line you are changing. Show all decreases in parentheses. 
                                                                                                                             Continued    1

Line 27
If you want your refund to be directly deposited into your checking or savings account, enter the routing and account numbers. You must use
an account not associated with any foreign banks.
The routing number must have nine digits. You can find your bank’s routing number and
account number on the bottom of your check.
The account number may contain up to 17 digits (both numbers and letters). Enter the number
and leave out any hyphens, spaces and symbols.
If the routing or account number is incorrect or is not accepted by your financial institution,
your refund will be sent to you in the form of a paper check.
By completing line 27, you are authorizing the department and your financial institution to initiate electronic credit entries, and if necessary,
debit entries and adjustments for any credits made in error.

Signature
The return must be signed by the principal officer of the organization receiving, controlling or managing the income of the S corporation. The
person must also include his or her ID number.
If someone other than the principal officer prepared the return, the preparer must also sign. The preparer’s PTIN and phone number should
also be included.
Check the box to authorize the department to discuss this return with the preparer. This authority allows us to discuss with your preparer
these items from this return: line item details; tax due on original and adjustments made during processing; penalty or interest due; documents
received or sent like a tax order or bill; and dates and amounts of payments, credits, or refunds. The authority also allows your preparer to
cancel direct deposit or debit payments and submit an abatement request.
The authority granted by a marked return checkbox is valid for one year after the due date for current original returns, or one year from the
date the form was submitted for amended and noncurrent original returns.
Checking the box does not give your preparer the authority to sign any tax documents on your behalf, represent you at any audit or appeals
conference, or discuss abatement progress. For these types of authorities, you must file Form REV184b, Business Power of Attorney, with the
department.
Email Address
If the department has questions regarding your return and you want to receive correspondence electronically, indicate the email address below
your signature. Check a box to indicate if the email address belongs to an employee of the S corporation, the paid preparer or other contact
person.
By providing an email address, you are authorizing the department to correspond with you or the designated person over the Internet and you
understand that the entity’s nonpublic tax data may be transmitted over the Internet.
You also accept the risk that the data may be accessed by someone other than the intended recipient. The department is not liable for any
damages that the entity may incur as a result of an interception.
