General Information

Forms
Which Form Should You File?
Most corporations, other than S corporations, file Form M4, Corporation Franchise Tax Return. 
S corporations filing federal Form 1120S must file Minnesota Form M8, S Corporation Return. 
Nonresident entertainers file Form ETR, Nonresident Entertainer Tax.
Exempt organizations file Form M4NP, Unrelated Business Income Tax Return. Exempt organizations include: 
•  Exempt organizations with unrelated business income and organizations liable for proxy tax on lobbying and political expenditures that file 
federal Form 990-T
•  Farmers’ cooperatives, as defined in IRC section 521, that file federal Form 1120-C 
•  Homeowner associations filing federal Form 1120-H
•  Political organizations filing federal Form 1120-POL 
Unit investment trusts. A unit investment trust, as defined in the Investment Company Act of 1940, is not considered a person, corporation, 
partnership, trust or investment company for Minnesota income tax purposes if it:
•  Issues periodic payment plan certificates
•  Has assets consisting mostly of a single management company’s securities
•  Has no power to invest in other types of securities
If a trust meets these conditions, no return needs to be filed. Each holder of an interest in the trust is considered to own a proportionate share 
of the assets and must report any distributions on their individual income tax return.
Real estate mortgage investment conduits (REMICs), valid under IRC section 860D[b], are not required to file a return. Holders of an 
interest in a REMIC must report their share of income or loss on their individual income tax returns.
Captive Insurance Companies
A captive insurance company is a company that is licensed as a captive insurance company, or derives less than 50% of its total premiums for 
the taxable year from sources outside the unitary business.
Unless disqualified, captive insurance companies are not subject to the Minnesota corporate franchise tax and are not part of the Minnesota 
combined group. They are not required to file an income tax return.
If a member of your combined group owns a captive insurance company, check the box on  page 1 of Form M4.
Disqualified Captive Insurance Companies
A disqualified captive insurance company is a captive insurance company that:
•  Pays less than 0.5% of its total premiums for the tax year in tax under MS 297I or a comparable tax of another state, OR 
•  Receives less than 50% of its gross receipts in the tax year from premiums. 
Disqualified captive insurance companies are required to file a corporate franchise tax return as part of the Minnesota combined group.
Software-Generated Forms
If you use tax preparation software, the information must be in the same format as our own forms and schedules. If it’s not in the same 
format, the forms and schedules will be returned to you for correction.

Due Dates and Extensions
When is the Return Due?
Returns, including short-year returns, must be filed by the due date for filing your federal income tax return. 
The U.S. postmark date, or date recorded or marked by a designated delivery service, is considered the filing date (postage meter marks are 
not valid). When the due date falls on a Saturday, Sunday or legal holiday, returns postmarked on the next business day are considered timely. 
When a return is filed late, the date it is received at the department is treated as the date filed.
The regular due date for returns filed by cooperative associations (other than IRC section 521 organizations) is the 15th day of the ninth 
month after the end of the calendar or fiscal year. Check the co-op box at the top of Form M4.
If You Need an Extension
All corporations are granted an automatic seven-month extension to file Form M4. You are not required to submit a form to Minnesota to 
receive the seven-month filing extension. 
If the Internal Revenue Service (IRS) grants an extension of time to file your federal return that is longer than the Minnesota automatic seven-
month extension, your state filing due date is extended to the federal due date. 
This is a filing extension only, not a payment extension. Any tax not paid by the regular due date is subject to penalties and interest (see 
instructions for lines 12 and 13 on page 6-7). 
                                                                                                                Continued                          2

General Information (continued)

To pay your extension payment electronically, see Paying Electronically on Page 3. If you make your extension payment by check, visit our 
website at www.revenue.state.mn.us and select Make a Payment and then By check to create a voucher. (Do not use a voucher if you’re 
making your extension payment electronically.)

Payments
Unitary businesses: Payments must be made under the designated filer. See Filing a Combined Return on page 4.
Paying Electronically
If, during the 12 months ending June 30 of the tax year, you paid $10,000 or more in estimated tax payments, you are required to make all 
future estimate tax payments electronically beginning January 1 of the following tax year. Once you meet the electronic payment threshold, 
you are required to pay electronically for all future periods.
You must also pay electronically if you’re required to pay any Minnesota business tax electronically, such as sales or withholding tax. See 
Payment Method under line 12 Penalty on pages 6 and 7.
Estimated Payments
If your estimated tax is more than $500, you must make quarterly payments based on the required annual payment.
The required annual payment must be paid in four equal installments unless certain exceptions apply (see instructions for Schedule M15C, 
Additional Charge for Underpayment of Estimated Tax). Payments are due by the 15th day of the third, sixth, ninth and 12th months of the 
tax year. Installments for a short tax year are due in equal payments on the 15th day of the third, sixth, ninth and final months of the tax year 
depending on the number of months in the short tax year. No installments are required for a short tax year of fewer than four months. 
You can make your payments electronically or by check by creating and printing a voucher on our website at www.revenue.state.mn.us. For 
the tax-year ending date, enter the ending date of the tax year for which the estimated tax payments are being made. The same date is used for 
all four quarterly payments. For example, if your tax year ends on December 31, 2023, enter December 2023 for all four payments. If your 
income is reported using a 52-53 week year, enter the month that ends nearest the last day of your taxable year. For example, if your taxable 
year goes from September 27, 2023 to October 3, 2024 (53 weeks), enter October 2024 on all four payment vouchers.
The required annual payment is the lesser of 100% of the prior year’s tax liability or 100% of the current year’s tax liability. A corporation is 
not required to pay estimated taxes the first year it is subject to tax in Minnesota.
For a large corporation, the required annual payment is 100% of the current year’s tax liability. A large corporation is one that had Minnesota 
taxable net income of $1 million or more in any of the three prior tax years. For the first quarter only, a large corporation may base its 
installment on 100% of the prior year’s tax liability. Any reduction in the installment from using this method must be added to the second 
installment. For making a large corporation determination, a unitary business is considered one corporation.
Tax Return Payment
If there is an amount due on line 15 of Form M4 and you are not required to pay electronically, you may pay by check by creating and 
printing a voucher on our website at www.revenue.state.mn.us.

   copies of all supporting schedules, except for federal Forms 1118, 1122, 3115, 5471, 5472 and 5713. Your Minnesota tax return will not be 
   considered complete unless all required federal returns are attached. We will accept the federal return in PDF format on a Compact Disc. Do 
   not staple or tape any enclosures to your return.
•  Where to file paper returns. Mail Form M4 and all completed Minnesota and federal forms and schedules using a mailing label (see page 
   16).

•  If this is your final return, check the correct box at the top of Form M4. Attach an explanation and a copy of merger papers, dissolution 
   date and distribution papers, or, for S corporations, a copy of your federal approval. 
•  If your M4 return shows a refund, Minnesota law requires you to provide your banking information so that your refund can  
   be deposited electronically.
Early Audits/Bankruptcy 
To request an early audit or notify the department of bankruptcy proceedings, complete Form M22, Request for Early Audit of Minnesota 
Income Tax Returns. If the corporation is in bankruptcy, check the “in bankruptcy” box at the top of Form M4.

Amending Your Return
Use Form M4X, Amended Franchise Tax Return, to report changes to your Minnesota liability or to claim a refund. 
If the IRS changes or audits your federal return or you amend your federal return and it affects your Minnesota return, you must amend your 
Minnesota return. File Form M4X within 180 days after you were notified by the IRS or after you filed your federal amended return. Enclose a 
copy of the IRS report or your amended federal return with your amended Minnesota return.
If you fail to report federal tax changes within 180 days, you are subject to a penalty equal to 10% of any additional tax due. In addition, the 
period of time increases during which we may make adjustments to your Minnesota return.

Unitary Businesses
Below are guidelines for corporations whose activities are part of a unitary business.
What is a Unitary Business?
“Unitary business” means business activities or operations that result in a flow of value and includes both foreign and domestic companies. A 
business is presumed to be unitary whenever there is unity of ownership, operation, and use. Unity is also presumed when business activities 
or operations are of mutual benefit, dependent upon or contributory to one another, either individually or as a group.
Unity of ownership exists when a corporation is a member of a group of two or more corporations and more than 50% of the voting stock 
of each member is directly or indirectly owned by a common owner, either corporate or noncorporate, or by one or more of the member 
corporations of a unitary business.
Unity of operation and use can be shown by centralized management or executive force; or centralized purchasing, advertising, accounting or 
other controlled activity.
The absence of these centralized activities does not necessarily mean that a business is not unitary. A business is unitary if there is functional 
integration, centralized management and economies of scale (MN Rule 8019.0100, subdp. 2a.B).
Filing a Combined Return
A unitary business must file a combined return. A combined return for Minnesota includes domestic corporations and disqualified captive 
insurance companies. A combined return does not include regulated investment companies. A combined return also includes foreign entities, 
other than those treated as C corporations for federal income tax purposes, which are included in the federal taxable income of the unitary 
business. Foreign corporations which are treated as C corporations for federal income tax purposes and regulated investment companies that 
have nexus with Minnesota, even if they are part of a unitary business, must file separate tax returns (see Definitions below).
One member of the unitary business must be selected as the designated filer to file the return, make payments, receive refunds, and represent 
the other members of the group in tax matters.
If you are filing a combined return, complete Schedule AFF, Affiliations for Combined Returns, and attach it to your return.
Using the Combined-Income Method 
The combined-income method uses single-sales factor apportionment to determine what percentage of the combined business income of a 
unitary business is reportable to Minnesota by each unitary business member required to file a Minnesota return.

                                                                                                                       Continued                 4

General Information (continued)

The apportionment factor for each member is determined by dividing the corporation’s sales or receipts attributable to Minnesota by the total 
sales of the entire group, both in and outside Minnesota. 
Income and deductions from transactions between members included in the combined return are eliminated to avoid distortion of the group’s 
income or of the sales apportionment factor.
The interest expense limitation under IRC 163(j) must be computed using the combined report entities included in the unitary group. The 
limitation must be aggregated between combined report entities consistent with the application to a consolidated group for federal income tax 
purposes.
For all members of a unitary business, sales or receipts attributable to Minnesota and made by any member that doesn’t have nexus with 
Minnesota must be included in the Minnesota sales reported by a member of the group which does have nexus with Minnesota.
If a corporation is part of a unitary business, the entire income (loss) derived from the trade or business of the unitary business is used  
to figure how much income or loss should be apportioned and reported by that corporation on the combined Minnesota tax return.  
Income not derived from the trade or business is assigned to Minnesota or another state. 
To determine the income (loss) from Minnesota sources for each member of the group, the total apportionable income (loss) of the entire 
group is multiplied by the apportionment factor of each member.
None of the apportionable income of a unitary business will be considered derived from any particular source or place except as determined 
by using the combined income method. 
Common Accounting Periods
The combined-income method for a group of related corporations requires the income and sales factors of all corporations be determined on 
the basis of a common accounting period.
If the members have different accounting periods, the income and sales factor computations of all members should be computed for the same 
period as the designated filer’s normal accounting period (MR 8019.0405, subp. 4).
The due date of the return is still determined according to the actual accounting period of the designated filer filing the Minnesota return.
Estimated Tax
Members of a unitary business must compute the estimated tax using the combined-income method. Estimated tax payments must be made 
by the designated filer only.

Definitions
Nexus
Corporations that are required to file a Minnesota tax return are referred to as having nexus with Minnesota.
Designated Filer
A unitary business filing a combined return must select one of its members to be the designated filer.
The designated filer’s name and tax ID numbers go on the face of the corporation franchise tax return and in the heading of Column B1 of each 
columnar schedule attached to the return. All payments (estimated, extension and tax return) will be made under the Minnesota tax ID number of 
the designated filer and any refunds will be issued to the designated filer.
Domestic Corporation
Any corporation organized under the laws of the United States or any state, the District of Columbia or political subdivision of these, excluding the 
Commonwealth of Puerto Rico or any possession of the United States. Domestic international sales corporations (DISCs), qualifying under IRC 
section 992(a), are also domestic corporations (MS 290.01, subd. 5).
Foreign Corporation
A corporation that doesn’t meet the definition of a domestic corporation is a foreign corporation (MS 290.01, subd. 5a). A foreign corporation 
which is taxed as a C corporation for federal income tax purposes and has nexus with Minnesota must file a separate return. 
                                                                                                                                                      5

Line 6—Minnesota Backup Withholding
Minnesota requires backup withholding to be made when the payee is subject to federal backup withholding on reportable payments made for 
personal services. (IRC section 3406). 
Corporations are not subject to backup withholding for certain types of payments, including: 
•  interest and dividends
•  broker transactions
•  royalty payments 
The Minnesota backup withholding is equal to the payment multiplied by the highest Minnesota tax rate for corporations. Report the 
taxpayer’s backup withholding on line 6 of Form M4.
Include a copy of the federal Form 1120, Form 1099, Schedule KPI, Schedule KS or other documentation showing the amount withheld. If 
the documentation is not included with your Form M4, the department will disallow the amount and assess the tax or reduce your refund.
Line 12—Penalty
Penalties are collected as part of the tax and are in addition to any additional charge for underpaying estimated tax. 
                                                                                                                       Continued              6

M4 Summary (continued)

Late payment. A penalty is due if you don’t pay at least 90% of your total tax by the regular due date. The penalty is 6% of the unpaid tax on 
line 11.
There is no penalty if at least 90% of your total tax is paid by the regular due date, and any remaining balance is paid by the extended due 
date. You must calculate interest on the remaining balance.
Late filing. If you file after the extended due date and owe tax, you must pay an additional penalty for filing late. The late-filing penalty is 5% of 
the unpaid tax on line 11. 
Balance not paid. An additional penalty of 5 percent of the unpaid tax is due if the return is filed after the regular due date with a balance 
due, and that balance is not paid at the time of filing.
Payment method. If you do not pay electronically when required, an additional 5 percent penalty applies to payments not made 
electronically.
Other Penalties. There are also civil and criminal penalties for intentionally failing to file a Minnesota return, evading tax, and for filing a 
frivolous, false, or fraudulent return. 
Line 13—Interest 
You must pay interest on the unpaid tax plus penalty from the regular due date until the total is paid. To figure how much interest you owe, 
use the following formula with the appropriate interest rate (the rate for 2024 is 8%): 
 Interest = (tax + penalty) x # of days late x interest rate ÷ 365
Line 14—Additional Charge for Underpayment of Estimated Tax
If you did not pay the correct amount of estimated tax by the due dates, you may have to pay an additional charge for underpayment of 
estimated tax. 
If your tax on Form M4, line 1 (less any credits on lines 4 and 5), is more than $500, use Schedule M15C, Additional Charge for 
Underpayment of Estimated Tax, to figure the additional charge or to show that you qualify for an exception. Attach Schedule M15C to your 
return.
Line 16
If line 10 is less than the sum of lines 3 and 12 through 14, subtract line 10 from the sum of lines 3 and 12 through line 14.
Signatures 
The return must be signed by a person authorized by the corporation. If you paid someone to prepare your return, the preparer must also  
sign and provide their Preparer Tax Identification Number (PTIN) and phone number. 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.

                                                                                                                                                  7

* There are circumstances when line 1a of your Form M4I does not equal line 29, Section II of your federal Form 1120-F. If the amounts do 
not match, you must complete Schedule REC, Reconciliation, and attach it to your Minnesota Form M4, Corporation Franchise Tax Return.
**1120-RIC: For Minnesota purposes, the federal taxable income of a regulated investment company must be increased by the net capital 
gain exclusion provided in IRC section 852(b)(2)(A). The dividend paid deduction must be applied by allowing a deduction for capital gains 
dividends and exempt interest dividends (IRC sections 852[b][3][C] and 852[b][5]). This also applies to any undistributed capital gains 
which are elected to receive IRC section 852(b)(3)(D) treatment.
Unitary Businesses
Because of differences in federal and state law, the amount on line 1a may not match the amount listed on your attached federal return. If it 
doesn’t match, complete Schedule REC, and attach it to your M4 return.
For example, line 28 on a consolidated Federal Form 1120 might not include income from companies that are part of a Minnesota combined 
return. Line 1a must include the income of those companies that meet the Minnesota definition of a unitary business but are not included on 
line 28 on a consolidated Form 1120. 
The consolidated Form 1120 does not include income from less-than-80-percent-owned companies. Minnesota’s definition of a unitary 
business only requires greater than 50% ownership.
Federal Form 1120, line 28, may include income from the following companies that should not be included on line 1a.
• Insurance companies that are not disqualified captive insurance companies.
• Investment companies
• Mexican and Canadian companies included in the federal consolidated return under provision 1504d of IRC.
• Non-unitary companies. These are members that don’t meet the definition of a unitary business.
The amount on line 1a must include income of those partnerships that meet the Minnesota definition of a unitary partnership. See RN 08-03 
for guidance on the treatment of income of corporate partners. Income from nonunitary partnerships must be excluded from Minnesota 
apportionable income. Nonunitary partnership income must either be excluded from line 1a or included on both line 1a and line 8. Enter the 
nonunitary partnership income which is assigned to Minnesota on Form M4T, line 4b.
Line 1b—Interest Expense Limitation
For entities with the same Minnesota combined group and federal consolidated group
If your Minnesota combined group is the same as your federal consolidated group, enter 0 on line 1b.
For entities with a different Minnesota combined group and federal consolidated group
The interest expense limitation under IRC section 163(j) must be aggregated between the Minnesota combined report entities consistent 
with the application to a federal consolidated group for federal income tax purposes. The tax attributes of the entities not included in the 
Minnesota combined group may not be included when determining the Minnesota limitations.
If your Minnesota combined group is different than your federal consolidated group, you may have to make an adjustment on Form M4I, line 
1b for interest expense limitation for Minnesota purposes. Use the federal Form 8990 as a worksheet to recalculate the Minnesota interest 
expense limitation for your Minnesota combined report. Write “Minnesota” at the top of this Form 8990 (referred to as Minnesota Form 
8990) and include it with your return.
If your interest expense allowable for Minnesota is less than your federal interest expense, enter the difference as a positive number on line 
1b. If your interest expense allowable for Minnesota is more than your federal interest expense, enter the difference as a negative number on 
line 1b.

Line 5—Intercompany Eliminations 
Attach a separate list explaining any duplication of income (loss) resulting from intercompany transactions and enter the amount on line 5. 
For example, if line 1a included $10,000 of dividends that were paid by one member to another, you would need to include that $10,000 on 
line 5. List any item of income as a positive amount and any item of loss as a negative amount. 
Dividends received by an insurer’s parent company from an insurer that is qualified and licensed in Minnesota, which is a member of an 
insurance holding company system as defined in MS 60D.15 subd. 6, should also be eliminated on this line. Attach a separate list explaining 
any dividends received from a Minnesota licensed and qualified insurer, which is a member of an insurance holding company system. 
For example, if line 1a included $10,000 of dividends that were paid by an insurer that is qualified and licensed in Minnesota, which is a 
member of an insurance holding company system, to include that $10,000 on Line 5. List any item of dividend income as a positive amount.
Line 8—Nonapportionable Income
Nonapportionable income is income that cannot be apportioned due to provisions of the United States Constitution. Nonapportionable income 
is allocated by assignment based on the type of property that gives rise to the income. Nonapportionable income must be reduced by the 
expenses incurred to generate the income. 
Frequently used assignment rules are:
•  Income/gains from tangible property not employed in the trade or business is allocated by assignment to the state in which the property is 
located.
•  Gain on the sale of a partnership interest not employed in the trade or business is allocated to Minnesota in the ratio of the original cost of 
partnership tangible property located in Minnesota to that located everywhere as determined at the time of the sale. If more than 50% of the 
value of the partnership’s assets are intangibles, the gain/loss is allocated to Minnesota using the partnership’s prior year sales factor.
Other assignment rules are in MS 290.17, subd. 2. Income not assigned in any particular manner is allocated by assignment to the taxpayer’s 
state of domicile.
All other types of income are referred to as business income, and are subject to apportionment.
If you are a corporate partner, include any nonapportionable income you received on line 2 of Schedule KPC. 

                                                                                                                                            11

M4A Apportionment/Minimum Fee

Minnesota uses a single-sales factor to determine the apportionment percentage. The minimum fee is calculated using 
property, payroll, and sales factors. Column A reports everywhere sales amounts. Column B reports Minnesota property, 
payroll, and sales amounts. 
If you are not a unitary business,complete Columns A and B1   .
If you are a unitary business, Column A must include the total sales of all corporations included on the combined return. 
Column B1 is for the designated filer. The remaining columns are for each of the other corporations in the group having nexus with 
Minnesota. If you need more than three columns, attach additional forms as needed.
Financial institutions, read Apportionment for Financial Institutions on page 14.

Property
In Column B 1(and remaining columns as needed by unitary business members having nexus with Minnesota), enter the property items for 
your business in Minnesota.
Line 1—Inventory
Add the beginning and ending year inventories and then divide by two. This is your average value of inventory for the tax year. Enter the 
result on line 1. 
Line 2—Tangible Property and Land
Add the beginning and ending year values of total tangible property (real, personal, and mixed) used in connection with your business during 
the tax year and then divide by two. Property must be valued at original cost and includes land, buildings, machinery, equipment and other 
tangible personal property. Enter the result on line 2.
Line 3—Capitalized Rents
Capitalized rents are based on the actual rent for property used during the tax year. Do not use an average of rents paid during the year to 
determine capitalized rents. Determine the value of rented property used by multiplying the rent paid for the tax year by eight.

Payroll
Line 5—Payroll
In Column B1 (and the remaining columns as needed by unitary groups), enter your total payroll paid or incurred in Minnesota, or paid for 
labor performed in Minnesota, for the tax year in connection with the business.

Sales
Line 6—Minnesota Sales or Receipts
In Column B 1(and in the remaining columns as needed by unitary business members having nexus with Minnesota) enter sales attributable to 
Minnesota made by the corporation listed at the top of the column. Financial institutions, see instructions on page 14.
The sales factor includes all sales, gross earnings or receipts received in the ordinary course of your business, except:
•  Interest
•  Dividends
•  Sales of capital assets under IRC section 1221
•  Sales of property used in the business, except sales of leased property that is regularly sold as well as leased
•  Sales of stock or sales of debt instruments under IRC section 1275(a)(1) 
•  Intercompany sales between members of a combined return
Line 7—Unitary Businesses Only
All sales of a unitary business attributable to Minnesota must be included on the group’s combined return, regardless of whether a specific 
group member has nexus with Minnesota.
On line 7, enter all sales of the unitary business attributable to Minnesota that were not included on line 6. Report the sales in whichever B 
column most benefits you.
The sales reported on line 7 are also used to calculate the minimum fee. (MS 290.17, subd. 4[h])
Line 8—Total Sales
In column A, line 8, enter the total sales for the tax year. Eliminate any transactions between members included in the combined return. In 
Column B 1 (and in the remaining columns as needed by unitary business members having nexus with Minnesota) add lines 6 and 7.

Determining Minnesota Sales
Real Property
Sales, rents, royalties and other income from real property are attributed to the state in which the property is located.

                                                                                                                                Continued      12

M4A Apportionment/Minimum Fee (continued)

Tangible Personal Property
Sales of tangible personal property are attributed to Minnesota if the property is received by the purchaser within Minnesota,  
regardless of the f.o.b. point, other conditions of sale, or the ultimate destination of the property. 
Tangible personal property delivered to a common or contract carrier or foreign vessel for delivery to a purchaser in another state  
or nation is a sale in that state or nation regardless of the f.o.b. point or other conditions of sale. 
Property is received by a purchaser in Minnesota if the recipient is located in this state, even if the property is ordered from outside Minnesota.
Sales of tobacco products, beer, wine and other alcoholic beverages to someone licensed to resell the products only within the state of 
ultimate destination is a sale in the destination state.
Receipts from leasing or renting tangible personal property, including finance leases and true leases, are attributed to the state in which the 
property is located. Receipts from the lease or rental of moving property are attributed to Minnesota to the extent the moving property is used 
in Minnesota. 
The extent of use is determined as follows:
•  A motor vehicle is used wholly in the state in which it is registered.
•  Receipts from rolling stock are assigned to Minnesota in the ratio of miles traveled in Minnesota to total miles traveled.
•  Receipts from aircraft are assigned to Minnesota in the ratio of landings in Minnesota to total landings.
•  Receipts from vessels, mobile equipment and other mobile property are assigned to Minnesota in the ratio of days the property is in  
Minnesota to the total days of the tax year.
Intangible Property
Sales of intangible property are attributed to the state in which the property is used by the purchaser. 
Royalties and other income received for the use of or privilege of using intangible property (such as patents, copyrights, trade names, 
franchises or similar items) are attributed to the state in which the property is used by the purchaser.
Intangible property is attributed to Minnesota if the purchaser uses the property, or rights in the property, to conduct business within this state, 
regardless of the location of the purchaser’s customers.
If the property is used in more than one state, then the sales or royalties must be apportioned to Minnesota pro rata based on the portion of use 
within this state. 
If you cannot determine the portion of use in Minnesota, then exclude the sales or royalties from both the numerator and the denominator of 
the sales factor.
Services
Receipts from the performance of services are attributed to the state in which the services are received. 
Receipts from services provided to a corporation, partnership, or trust may only be attributed to a state in which it has a fixed place of doing 
business.
If you can’t determine where the service was received, or if it was received in a state where the corporation, partnership, or trust doesn’t have a 
fixed place of business, use the location of the office of the customer from which the service was ordered.
If you can’t determine the ordering office, use the office location to which the service was billed. 

Petitioning to Use Another Method of Allocation
State law (MS 290.20, subd. 1a and Minnesota Rules 8020.0100, subp. 3) allows entities to request permission from the department to allocate 
all, or any part of, taxable net income in a manner other than single-sales factor apportionment.
To request permission, complete Form ALT, Petition to Use Alternative Method of Allocation (see Revenue Notice 04-07).
Permission will be granted only if you can show that single-sales factor apportionment does not properly and fairly reflect your Minnesota 
income, and that the alternative formula you have chosen does.

Minimum Fee
A corporation is subject to a minimum fee if the sum of its Minnesota source property, payroll and sales or receipts is at least $1,080,000. The 
minimum fee is in addition to the regular tax and the alternative minimum tax. 
Entities that are exempt from the minimum fee include:
•  Regulated investment companies (RICs)
•  Real estate investment trusts (REITs)
•  Real estate mortgage investment conduits (REMICs)
Line 10—Adjustments
The minimum fee is determined by your total Minnesota property, payroll and sales.                                              Continued  13

M4A Apportionment/Minimum Fee (continued)

In some cases the property, payroll and sales used for computing the minimum fee will be different than those used for apportionment. The 
following adjustments should be made to your Minnesota factors on line 10.
Add: All tangible property owned or rented that is not included on line 4 of Form M4A. Some examples include construction in progress, 
idle property and any nonbusiness property or rent expense. The amounts should be determined in the same manner as the amounts on line 4.
Subtract:
•  Any partnership amounts included on lines 4, 5 and 8.
•  Any sales or receipts from an air carrier business.
•  Reduction of property owned for a short taxable year. To determine, multiply the amount included on line 1 and line 2 for that property by 
a fraction: the numerator is 365 minus the number of days in the tax year; the denominator is 365.
Enclose a schedule showing the computation and pass-through information of any adjustments listed on M4A, line 10.

1) Any corporation or other business entity registered
•  Under state law as a bank holding company
•  Under the federal Bank Holding Company Act of 1956, as amended
•  As a savings and loan holding company under the federal National Housing Act, as amended
2) Any regulated financial corporation; or a national bank organized and existing as a national bank association pursuant to the provisions of
