General Franchise or Income Tax Return Instructions 

Who Must File 

Organizations Required to File. The following exempt organizations are required to file a Wisconsin corporation 
franchise or income tax return: 
•  Organizations exempt from Wisconsin income taxation under sec. 71.26(1)(a) or 71.45(1), Wis. Stats., which sat-
 isfy, or which are the sole owner of limited liability companies (LLCs) that satisfy, all the following: 
   Do business in Wisconsin, 
   Have at least $1,000 of gross income from an unrelated trade or business for federal income tax purposes, 
  and 
   Must file federal Form 990-T or 4720 to report such unrelated trade or business income. 
•  Trusts exempt from federal income tax under Internal Revenue Code (IRC) section 501(a), which satisfy all the 
 following:  
   Have income from Wisconsin sources, such as business transacted or property located in Wisconsin, 
   Have at least $1,000 of gross income from an unrelated trade or business for federal income tax purposes, 
  and 
   Must file federal Form 990-T, 4720, or 5227. 
•  IRAs and MSAs described in IRC sections 408(a) and 220(d) which satisfy all the following:  
   Have income from Wisconsin sources, such as business transacted or property located in Wisconsin, 
   Have at least $1,000 of gross income from an unrelated trade or business for federal income tax purposes, 
  and 
   Must file federal Form 990-T or 4720. 
•  Exempt organizations engaged in buying or selling lottery prizes if the winning tickets were originally bought in 
 Wisconsin. 

“Gross income” of a manufacturing, merchandising, or mining business is the total receipts or sales, less the cost of 
goods sold, plus the gross income from other sources that is includable in unrelated business taxable income. 

“Doing business in this state.” The definition of “Doing business in this state,” sec. 71.22(1r), Wis. Stats, includes 
regularly selling products or services of any kind or nature to customers in Wisconsin that receive the product or 
service in Wisconsin; regularly soliciting business from potential customers in Wisconsin; regularly performing ser-
vices outside Wisconsin for which the benefits are received in Wisconsin; regularly engaging in transactions with 
customers in Wisconsin that involve intangible property and result in receipts flowing to the taxpayer from within 
Wisconsin; and holding loans secured by real or tangible personal property located in Wisconsin. “Regular" and 
“regularly" mean 15 or more days of activity. Fifteen days of activity means one person for 15 days or 15 persons for 
one day, or any combination of persons and days that results in at least 15 person-days of activity. “Days of activity” 
include any day, or portion thereof, upon which business activity took place. “Days of activity” do not include travel 
days, holidays, or weekends, unless business activities were conducted on those days. 

Organizations Not Required to File. The following organizations are not required to file a Wisconsin corporation 
franchise or income tax return: 
•  Exempt organizations that aren’t subject to tax on unrelated business taxable income under IRC section 511 and 
 aren’t required to file federal Form 990-T, except those with income realized from the sale of or purchase and 
 subsequent sale or redemption of lottery prizes if the winning tickets were originally bought in Wisconsin. 
•  Employee benefit plans established by an employer engaged in or affecting interstate commerce or by an em-
 ployee  organization that represents employees  engaged  in  or affecting interstate commerce. This  exception 
 doesn’t apply to government plans, church plans not electing under the vesting, etc., provisions, worker’s com-
 pensation plans, non-U.S. plans primarily for nonresident aliens, and “excess benefit plans.” 

IC-102 (R. 11-23)                                                     2 

                                      2023 Wisconsin Form 4T Instructions 

•  The State of Wisconsin, including the University of Wisconsin System, or any county, village, school district, or 
  other political unit of the State of Wisconsin. 
•  Credit unions. 

 When and Where to File  

 Generally, an exempt organization must file Form 4T by the 15th day of the 5th month following the close of its taxable 
 year. However, an employees’ trust defined in IRC section 401(a), an IRA, and an MSA must file Form 4T by the 15th 
 day of the 4th month following the close of the taxable year. If a return is filed late, without an extension, the exempt 
 organization may be subject to penalties and interest. 

 Extensions. If you are requesting an extension of time to file your federal income tax return, the following treatment 
 applies: 
 •  For exempt organizations taxable as corporations, any extension allowed by the Internal Revenue Service (IRS) 
  for filing the federal return automatically extends the Wisconsin due date to 30 days after the federal extended 
  due date. You don’t need to submit either a copy of the federal extension or an application for a Wisconsin exten-
  sion to the department by the original due date of your return. However, you must file a copy of the federal exten-
  sion with the Wisconsin return that you file. 
•  For exempt organizations taxable as trusts, any extension allowed by the IRS for filing the federal return automat-
  ically extends the Wisconsin due date to the federal due date. You must file a copy of the federal extension with 
  the Wisconsin return that you file. 
• Disaster Relief Extension. If you are filing under extension because of a federal or state disaster, include a 
  statement indicating which disaster extension you are using and attach it to your return. Additional information on 
  disaster areas can be found here:  revenue.wi.gov/Pages/FAQS/pcs-extensn.aspx#ext5 
   
Filing Return 

If you file your return on paper, follow these mailing instructions carefully: 
• Do not fasten, staple, or bind the pages of your return. Use paper clips instead. 
 •  If you are submitting multiple returns, separate them with colored separator sheets. 
 •  Use the mailing address shown on the form. 

 Period Covered by Return 

 The return must cover the same period as the exempt organization’s federal business income tax return, Form 990-T. 
 A 2023 Wisconsin return must be filed by an exempt organization for calendar year 2023 or a fiscal year that begins 
 in 2023. A fiscal year may end only on the last day of a month. The period covered by the return can’t exceed 12 
 months. 

 Example:  Corporation A has a fiscal year beginning March 1, 2023, and ending February 29, 2024.  Corporation A 
files a 2023 Form 4T for the period of March 1, 2023, through February 29, 2024.    
 
However, exempt organizations reporting on a 52–53 week period for federal tax purposes must file on the same 
reporting period for Wisconsin. A 52–53 week taxable year is deemed to begin on the first day of the calendar month 
beginning nearest to the first day of the 52–53 week taxable year. The taxable year is deemed to end on the last day 
of the calendar month closest to the last day of the 52–53 week taxable year for purposes of due dates, extensions, 
and assessments of interest and penalties. 

Any change in accounting period made for federal purposes must also be made for Wisconsin purposes. For the first 
taxable year for which the change applies, file with the Wisconsin return a copy of the IRS’s notice of approval of 
accounting period change if such approval is required or an explanation of the change if the IRS’s approval isn’t 
required. 

IC-102 (R. 11-23)                                                           3 

                                      2023 Wisconsin Form 4T Instructions 

Accounting Methods and Elections 

In computing unrelated business taxable income, the method of accounting must be the same method used in com-
puting federal unrelated business taxable income. However, if the method used for federal purposes isn’t authorized 
under the IRC in effect for Wisconsin, use a method authorized under the IRC in effect for Wisconsin. 

Change in Accounting Method. A change in accounting method made for federal purposes must also be made for 
Wisconsin purposes, unless the change isn’t authorized under the IRC in effect for Wisconsin. Adjustments required 
federally as a result of a change made while the exempt organization is subject to Wisconsin taxation must also be 
made for Wisconsin purposes, except in the last year that an exempt organization is subject to taxation by Wisconsin 
it must take into account all remaining adjustments required. 

For the first taxable year for which the change applies, file with the Wisconsin return either a copy of the application 
for change in accounting method filed with the IRS and copy of the IRS’s consent, if applicable, or an explanation of 
the change if the IRS’s approval isn’t required. 

Elections. As explained above, an exempt organization can’t make different elections for federal and Wisconsin 
purposes with respect to accounting periods and accounting methods, unless the federal method isn’t permitted under 
the IRC in effect for Wisconsin. In situations where an exempt organization has an option under the IRC and the IRS 
doesn’t consider that option to be a method of accounting, a different election may be made for Wisconsin than that 
made for federal purposes. If federal law specifies the manner or time period in which an election must be made, 
those requirements also apply for Wisconsin purposes. For more information, see Wisconsin    Tax Bulletin 214  (July 
2021, page 8). 
 
If different elections are made, adjustments are required on the Wisconsin return to account for any differences. 
Exempt organizations enter such adjustments on Part 1 or Part 2.  

Payment of Estimated Tax 

The franchise or income tax and economic development surcharge must be paid by the 15th day of the 5th month 
(15th day of the 4th month for employees’ trusts, IRAs, and MSAs) following the close of the taxable period, regard-
less of the due date of the return. Exempt organizations may be required to make quarterly estimated payments to 
prepay their franchise or income tax and economic development surcharge.  

If the total of an exempt organization’s franchise or income tax and economic development surcharge due is $500 or 
more, it generally must make quarterly estimated tax payments. Corporations should use Wisconsin Form Corp-ES 
or make payment by electronic funds transfer, and trusts should use Form 1-ES or make payment by electronic funds 
transfer. Failure to make required estimated tax payments may result in an interest charge. 

 CAUTION: An extension for filing the return doesn’t extend the time to pay the franchise or income tax. Interest 
 will be charged on the tax and surcharge not paid by the original due date. You can avoid interest charges during 
 the extension period by paying the tax and surcharge due by the original due date. Submit your payment with 
 Wisconsin Form Corp-ES, Corporation Estimated Tax Voucher. 
                                                                                                                    
Quick Refund.   An exempt corporation that overpaid its estimated tax may apply for a refund before filing its tax 
return if its overpayment is (1) at least 10% of the expected Wisconsin tax liability and (2) at least $500. To apply, file 
Wisconsin Form 4466W,   Corporation or Pass-Through Entity Application for Quick Refund of Overpayment of Esti-
mated Tax, after the end of the taxable year and before the exempt corporation files its tax return. Do not file Form 
4466W at the same time as your tax return. 

An exempt corporation that has a tax due when filing its tax return as a result of receiving a “quick refund” will be 
charged 12% annual interest on the amount of unpaid tax from the date the refund is issued to the earlier of the 15th 
day of the 5th month (15th day of the 4th month for employees’ trusts, IRAs, and MSAs) after the close of the taxable 
year or the date the tax liability is paid. Any tax that remains unpaid after the unextended due date of the tax return 
continues to be subject to 18% or 12% annual interest, as appropriate. 

IC-102 (R. 11-23)                                                       4 

                                    2023 Wisconsin Form 4T Instructions 

Disclosure of Related Entity Expenses and Reportable Transactions 

An exempt organization may be required to separately disclose certain expenses paid, accrued, or incurred to a 
related entity. An exempt organization or its material advisor may also be required to separately disclose reportable 
transactions. 

 CAUTION: Wisconsin law provides that certain related entity expenses shall not be allowed as deductions if they 
 are not timely disclosed as required by the Department of Revenue. Also, penalties may apply for failure to disclose 
 reportable transactions to the department. 
                                                                                                                          
Disclosure of Related Entity Expenses. If the exempt organization will be deducting more than $100,000 (after 
considering the effect of apportionment) of interest, rent, or intangible expenses or management fees paid, accrued, 
or incurred to a related person or entity, the corporation must generally file Schedule RT,    Wisconsin Related Entity 
Expenses Disclosure Statement, with its franchise or income tax return. The Schedule RT instructions explain the 
reporting requirements. 

However, even if you are not required to file Schedule RT, if you are taking deductions for interest, rent, or intangible 
expenses or management fees paid, accrued, or incurred to related entities, you must add those expenses back to 
federal income as Wisconsin modification. If the expenses meet the tests for deductibility, you may subtract them out 
as subtraction modifications. 

Organization’s Disclosure of Reportable Transactions. If an exempt organization was required to include any 
form with its federal tax return to disclose a “reportable transaction,” as defined under sec. 71.81(1)(c), Wis. Stats. ,it 
must file a copy of that form with the Department of Revenue within 60 days of the date it is required to file it for 
federal income tax purposes, provided it is otherwise required to file a Wisconsin return. This includes federal Form 
8886, Reportable Transaction Disclosure Statement.  

See the instructions to federal Form 8886 to determine if you are required to file the form for federal purposes. 

Material Advisor’s Disclosure of Reportable Transactions. A “material advisor” means any person who provides 
any material aid, assistance, or advice with respect to organizing, managing, promoting, selling, implementing, insur-
ing, or carrying out any reportable transaction (as defined in the U.S. Treasury Regulations) and who, directly or 
indirectly, derives gross income from providing such aid, assistance, or advice in an amount that exceeds the thresh-
old amount. 

For a material advisor providing advice to an entity and not an individual, the “threshold amount” is any of the follow-
ing: 

•  $25,000 if the reportable transaction is a listed transaction (as defined in the U.S. Treasury Regulations). 
•  $250,000 if the reportable transaction is not a listed transaction.  

For a material advisor providing advice to an individual, the “threshold amount” is any of the following: 
•  $10,000 if the reportable transaction is a listed transaction (as defined in the U.S. Treasury Regulations). 
•  $50,000 if the reportable transaction is not a listed transaction. 

A material advisor that is required to disclose a reportable transaction to the IRS must file a copy of the disclosure 
with the Department of Revenue within 60 days of the date it is required for federal income tax purposes, if the 
reportable transaction affects the taxpayer’s Wisconsin income or franchise tax liability. For federal purposes, the 
form required for this disclosure is Form 8918. 

If you are required to file Form 8918 for federal income tax purposes and the reportable transaction to which the form 
relates affects the taxpayer’s Wisconsin income or franchise tax liability, send a paper copy, separate from the Wis-
consin return, to the following address: Wisconsin Department of Revenue, Tax Shelters Program, PO Box 8906, 

IC-102 (R. 11-23)                                                         5

Madison, WI 53708-8906. Include a listing of the names and identification numbers of each Wisconsin taxpayer for 
whom the advisor provided services to. 

Internal Revenue Service Adjustments, Amended Returns, and Claims for Refund 

Internal Revenue Service Adjustments. If an exempt organization’s federal tax return is adjusted by the IRS and 
such adjustments affect the Wisconsin net tax payable, the amount of a Wisconsin credit, or a Wisconsin loss car-
ryforward, you must report such adjustments to the Department of Revenue within 180 days after they become final 
by either filing an amended Wisconsin franchise/income tax return or mailing a copy of the final federal audit report. 

Send a copy of the final federal audit reports and any associated amended Wisconsin returns to the Wisconsin De-
partment of Revenue, PO Box 8908, Madison,  WI  53708-8908. If submitting  a federal  audit report without an 
amended return, mail it to the Audit Bureau, Wisconsin Department of Revenue, Mail Stop 3-107, PO Box 8906, 
Madison, WI 53708-8906. Don’t attach these items to the tax return for the current year. 

Amended Returns. After you have filed a complete, original tax return, you may file an amended return to correct a 
tax return as you originally filed it or as it was later adjusted by an amended return, a claim for refund, or an office or 
field audit. 

If you file an amended federal return and the changes affect the Wisconsin net tax payable, the amount of a Wisconsin 
credit, or a Wisconsin loss carryforward, you must file an amended Wisconsin return with the Department of Revenue 
within 180 days after filing the amended federal return. 

To file an amended Wisconsin return, put a check mark on the line next to item D1 on the front of the return, complete 
the return, and include Schedule AR to explain any changes made. Show computations in detail, including any ap-
plicable supplemental forms or schedules. Also show how you figured your refund or additional amount owed. 

Where applicable, the line-by-line instructions in this booklet provide specific instructions for how to compute the 
amounts on an amended return. 

Claims for Refund. A claim for refund must be filed within 4 years of the unextended due date of the return. However, 
a claim for refund to recover all or part of any tax or credit paid as a result of an office or field audit must be filed 
within 4 years after such an assessment. That assessment must have been paid and must not have been protested 
by filing a petition for redetermination. See section Tax 2.12, Wisconsin Administrative Code, for more information. 

Economic Development Surcharge 

The economic development surcharge applies to corporations having gross receipts from all unrelated trade or busi-
ness activities of $4 million or more during the taxable year. Corporations that must file Wisconsin franchise or income 
tax returns must pay the economic development surcharge, with certain exceptions. The surcharge doesn’t apply to: 

•  Exempt corporations that have less than $4 million of gross receipts from all unrelated trade or business activities 
 for federal income tax purposes. 
•   “Gross receipts from all unrelated trade or business activities” includes gross receipts, gross sales, the gross sales 
 price from the disposition of capital assets and business assets, gross rents, gross income from unrelated debt-
 financed property, gross interest, annuities, royalties, and rents from controlled organizations, gross investment 
 income, gross exploited exempt activity income, gross advertising income, gross receipts passed through from 
 other entities, and all other receipts that are included in unrelated business taxable income for Wisconsin income 
 tax purposes. 

For more information, refer to Publication 400, Wisconsin’s Economic Development Surcharge.

Information Returns 

If an exempt organization pays $600 or more in rents, royalties, or certain nonwage compensation to one or more 
individuals, the exempt organization must file an information return to report those payments. You may use Wisconsin 
Form 9b, Miscellaneous Income, or you may use federal Forms 1099 or 1099-NEC instead of Form 9b. For more 
information, see the Form 9b instructions. 

Wisconsin Use Tax 

Exempt organizations that don’t hold a Wisconsin Certificate of Exempt Status (CES#) and purchase taxable tangible 
personal property, certain coins and stamps, certain leased properties affixed to real estate, certain digital goods, or 
taxable services for storage, use, or consumption in Wisconsin without payment of a sales or use tax may owe 
Wisconsin state, county, or stadium use tax and be required to file a Wisconsin sales and use tax return.

sin Department of Revenue, Mail Stop 5-77, PO Box 8946, Madison, WI 53708-8946. 

Penalties for Not Filing or Filing Incorrect Returns 

If you don’t file a Form 4T that you are required to file, or if you file an incorrect Form 4T due to negligence or fraud, 
interest and penalties may be assessed against you. The interest rate on delinquent taxes is 18% per year. Civil 
penalties may be as much as 100% of the amount of tax not reported on the return. Criminal penalties for filing a 
false return include a fine of up to $10,000 and imprisonment. Further, if you fail to disclose reportable transactions, 
you may be subject to the penalties described in sec. 71.81, Wis. Stats., including a $30,000 penalty for failure to 
disclose a listed transaction. 

Conformity With Internal Revenue Code and Exceptions 

The Wisconsin income and franchise tax law applicable is based on the federal Internal Revenue Code (“IRC”). The 
IRC generally applies for Wisconsin purposes at the same time as for federal purposes. For taxable years beginning

Below is a listing of the exceptions. 

Note: The exceptions and provisions adopted by Wisconsin listed below are those in effect as of the publication date

Other Exceptions to Internal Revenue Code 

The following federal provisions in effect as of December 31, 2022, are specifically excluded for Wisconsin franchise 
and income tax purposes: 

Depreciation and Bonus Depreciation 
 
For taxable years beginning on or after January 1, 2014, for purposes of computing depreciation, depletion, and 
amortization, the Internal Revenue Code means the federal Internal Revenue Code in effect on January 1, 2014. 
 
The provision that property required to be depreciated for taxable year 1986 under the Internal Revenue Code as 
amended to December 31, 1980, to continue to be depreciated under the Internal Revenue Code as amended to 
December 31, 1980, is limited to taxable years beginning before January 1, 2014. 

Wisconsin has not adopted federal bonus depreciation provisions.  For Wisconsin purposes, depreciation, de-
pletion, and amortization is computed based on the Internal Revenue Code in effect on January 1, 2014. 

Section 179 Expense 

Wisconsin has adopted federal section 179 expense provisions. For taxable years beginning on or after January 1, 
2014, sections 179, 179A, 179B, 179C, 179D, and 179E of the Internal Revenue Code, related to expensing of 
depreciable business assets, apply for Wisconsin tax purposes. "Internal Revenue Code" means the federal Internal 
Revenue Code in effect for the year in which the property is placed in service. 

Accounting for Differences 

Adjustments may be necessary to account for differences between federal and Wisconsin taxable income because 
of the items described above. Exempt organizations show these adjustments on Part 1 and Part 2. See the instruc-
tions for line 1 for details.

                                      2023 Wisconsin Form 4T Instructions 

Line-by-Line Instructions for Form 4T 

You must complete pages 1 and 2 of Form 4T and make appropriate entries on page 3. Do not enter “See attached” 
instead of completing the entry spaces. If more space is needed, use separate sheets using the same size and format 
as the printed forms. 

Round cents to the nearest whole dollar by eliminating amounts less than 50 cents and increasing amounts from 50 
cents through 99 cents to the next higher dollar. 

The name and address information should be written on single lines.  Do not stack the information on the lines. If 
more room is needed, abbreviate where possible.   

Do not write "None" on the amount lines if there is not an entry for the lines.  Instead, leave the lines blank.   

Caution: Federal  line numbers referred to on Form  4T and  in these instructions may change  if  the IRS makes 
changes to their forms after this form is finalized. 

Items A Through J 

Before completing items A through J, fill in the exempt organization’s 2023 taxable year at the top of the form and 
the organization’s name and address. If the organization dissolved, enter the date of dissolution as the ending date 
of the 2023 taxable year. 

■ Item A. Federal Employer Identification Number – Enter the exempt organization’s federal employer identifica-
tion number (EIN). If you haven’t yet applied for a federal EIN, you may do so by filing federal Form SS-4 with the 
IRS, calling the IRS’s toll-free number at (800) 829-4933, or applying online at http://www.irs.gov/Businesses/Small-
Businesses-&-Self-Employed/Apply-for-an-Employer-Identification-Number-(EIN)-Online. 

■ Item B. Business Activity (NAICS) Code – Enter the organization’s principal business activity code, based on the 
North American Industry Classification System (NAICS), from your federal return. If your federal return is a consoli-
dated return, go to census.gov/naics/ to find the NAICS code for your principal business activity. 

■ Item C. State and Year of Organization – Enter the 2-letter postal abbreviation for the state (or name of the foreign 
country) under whose laws the organization was formed or organized and the year of formation or organization.  

■ D1. Amended Return – Check here if this is an amended return. Include Schedule AR detailing the lines you are 
changing and any supporting form or schedule. 

■ D2. First Return – Check here if this is the first year that you are filing a Wisconsin return because the corporation 
wasn’t in existence or didn’t do business in Wisconsin in prior years. 

■ D3. Final Return – If the corporation ceased to exist or withdrew from Wisconsin during the year and will no longer 
be filing Form 4T, check here and submit a copy of your plan of liquidation and federal Form 966 if the corporation 
liquidated.  

Note: checking this box will not close all your accounts with the department; only the corporation account will close. 

■ D4-5. Short Period – Indicate that a short period return is being filed due to a change in the corporation’s account-
ing period or a stock purchase or sale by checking the appropriate line. 

Be sure to use the correct year's tax return when filing for a short period.  If the tax returns are not yet available, wait 
until the returns become available and file under extension.  For example, if a taxpayer has a short period from 
January 1, 2024 through February 28, 2024, the 2024 Form 4T will not be ready by July 15, 2024 (unextended due 
date for a February 28 year-end).  Wisconsin law follows the federal extension provisions but provides for an addi-
tional 30-day extension beyond the federal extension, so filing under extension will allow the correct years return to 
be filed when the 2024 Form 4T is available (typically November 1).  Note that an extension does not extend the time 
to pay a balance due.  To avoid interest charges, pay the amount due by the unextended due date.

return and enter the extended due date. 

Disaster Relief Extension. If you are filing under extension because of a federal or state disaster, include a state-
ment indicating which disaster extension you are using and attach it to your return. Additional information on disaster 
areas can be found here:  revenue.wi.gov/Pages/FAQS/pcs-extensn.aspx#ext5 
 
■ Item F. Schedule RT Required – Check here if the exempt organization is filing Schedule RT, Wisconsin Related 
Entity Expenses Disclosure Statement, with its return. Schedule RT is generally required if the exempt organization 
pays, accrues, or incurs more than $100,000 of expenses to a related person or entity in the taxable year. See the 
Schedule RT instructions for details of the requirement to file Schedule RT. 

■ Item G. Name Change - Check here if the organization changed its name during the taxable year.   

■ Item H. Internal Revenue Service Adjustment – If an organization’s federal tax return is adjusted by the IRS and 
the adjustments affect the Wisconsin net tax payable, the amount of a Wisconsin credit, a Wisconsin net business 
loss carryforward, or a Wisconsin capital loss carryforward, you must report the adjustments to the Department of 
Revenue within 180 days after they become final. 

Send a copy of the final federal audit reports and any associated amended Wisconsin returns to the Wisconsin De-

■ Line 1. Federal Unrelated Business Taxable Income – Enter the amount from federal Form 990-T, Part I, line 
11. This is federal unrelated business taxable income after the net operating loss deduction and special deductions.

winning tickets were originally bought in Wisconsin must be reported to Wisconsin.   

Tax-exempt corporations are required to make adjustments to Part 1 -       Additions and Part 2 - Subtractions on Form 
4T unless the adjustments are not required because of how the exempt entity computes its unrelated business taxable 
income under IRC sec. 512.   

If any changes to the IRC or depreciation or amortization differences described above affect the computation of 
federal unrelated business taxable income but don’t apply for Wisconsin purposes, enter the adjustments on lines 2 
or 4. 

■ Line 2 – Additions – Enter the total additions from Part 1 on page 3.  

Instructions for how to complete Part 1 - Additions: 

• Line 1. Interest Income – Enter interest income, less related expenses, received on state and municipal obliga-
  tions that was excluded from federal unrelated business taxable income, except interest which is by law exempt

  See page 3 of the Schedule RT instructions for further details of the expenses required to be disclosed on Schedule 
  RT and added back to income on Part 1 of Schedule RT. 

  After the corporation makes this addition modification, the corporation uses Part II of Schedule RT to determine if 
  it is eligible for a deduction for any of the amount added back. The corporation then makes a subtraction modifica-
  tion on Part 2 in the amount it is eligible to deduct. 
  If the corporation is a partner, member, or beneficiary of a pass-through entity, also include the amount of modifi-
  cation included on line 22a of Schedule 3K-1 and line 14a of Schedule 2K-1, as applicable.

  ification to “add back” management fees, intangible expenses, interest expenses, or rental expenses that are paid, 
  accrued, or incurred to a related entity if that interest was deducted from federal unrelated business taxable income. 
  The “addback” is reported on Part 1, line 5. After the corporation makes this addition modification, it completes Part 
  II of Schedule RT to determine if it is eligible for a deduction for any of the amount added back. The corporation 
  then makes a subtraction modification on Part 2, line 4, for the amount it is eligible to deduct. See the Schedule RT 
  instructions for details of the conditions necessary to claim this subtraction. 
   
  If the corporation is a partner, member, or beneficiary of a pass-through entity, also include the amount of modifi-

  grams is included in federal income according to sec. 61, IRC, unless an exception applies. Income from 
  these programs included in federal income should be excluded for Wisconsin by making a subtraction modi-
  fication. For the description, use "Wisconsin COVID-19 Program Funds." 
   
■ Line 5. Nonapportionable and Separately Accounted Income –  

Nonapportionable Income – Form N: 

Nonapportionable income is that income which is allocable directly to a particular state. It includes income or loss 
derived from the sale of nonbusiness real or tangible personal property or from rentals and royalties from nonbusiness 
real or tangible personal property. This income is assigned to the state where the property is located. 

All income that is realized from the sale of or purchase and subsequent sale or redemption of lottery prizes if the 
winning tickets were originally bought in Wisconsin shall be allocated to Wisconsin. 

Except for income from lottery prizes described above, the intangible income of a personal holding company is non-
apportionable and is assigned to the state of incorporation. 

Total nonapportionable income (loss) is removed from total company net income before the apportionment percent-
age is applied using Form N. The Wisconsin nonapportionable income (loss) is then combined with the Wisconsin 
apportionable income to arrive at Wisconsin net income. 

Separate Accounting – Forms C and N: 

If using the separate accounting method, don’t complete lines 5 through 9. An exempt organization engaged in a 
nonunitary business in and outside Wisconsin must determine the amount of income attributable to Wisconsin by 
separate accounting. The exempt organization uses Form C,                Wisconsin Allocation and Separate Accounting Data, 
to compute the amount attributable to Wisconsin by separate accounting and uses Form N, Wisconsin Nonappor-
tionable, Separately Accounted, and Separately Apportioned Income, to report the separate accounting amount. This 
is because the income determined under separate accounting from Form C, line 16 is entered on Form N, line 6. A 
nonunitary business is one in which the operations in Wisconsin aren’t dependent upon or contributory to the opera-
tions outside Wisconsin. Under separate accounting, the exempt organization must keep separate records of the 
sales, cost of sales, and expenses for the Wisconsin business. 

■ Lines 6 through 8. Apportionment Data – If using the apportionment method, complete one of the following 
schedules to compute the apportionment percentage: 

• Schedule A-01, Wisconsin Single Sales Factor Apportionment Data for Nonspecialized Industries 
• Schedule A-02, Wisconsin Apportionment Percentage for Interstate Financial Institutions,  
• Schedule A-03, Wisconsin Apportionment Percentage for Interstate Motor Carriers,  
• Schedule A-04, Wisconsin Apportionment Percentage for Interstate Telecommunications Companies,  
• Schedule A-05, Wisconsin Premiums Factor for Insurance Companies,  
• Schedule A-06, Wisconsin Receipts Factor for Interstate Brokers-Dealers, Investment Advisors, Investment Com-
  panies, and Underwriters,  
• Schedule A-07, Wisconsin Apportionment Percentage for Interstate Air Carriers,  
• Schedule A-08, Wisconsin Apportionment Percentage for Broadcasters,  
• Schedule A-09, Wisconsin Apportionment Percentage for Interstate Railroads,  
• Schedule A-10, Wisconsin Apportionment Percentage for Interstate Pipeline Companies,   or
• Schedule A-11, Wisconsin Apportionment Percentage for Interstate Air Freight Forwarders Affiliated with a Direct

■ Line 9. Wisconsin nonapportionable and Separately Accounted Income –  

Nonapportionable Income – Form N: 

Nonapportionable income is that income which is allocable directly to a particular state. It includes income or loss 
derived from the sale of nonbusiness real or tangible personal property or from rentals and royalties from nonbusiness 
real or tangible personal property. This income is assigned to the state where the property is located. 

All income that is realized from the sale of or purchase and subsequent sale or redemption of lottery prizes if the 
winning tickets were originally bought in Wisconsin shall be allocated to Wisconsin. 

Except for income from lottery prizes described above, the intangible income of a personal holding company is non-
apportionable and is assigned to the state of incorporation. 

Total nonapportionable income (loss) is removed from total company net income before the apportionment percent-
age is applied using Form N. The Wisconsin nonapportionable income (loss) is then combined with the Wisconsin 
apportionable income to arrive at Wisconsin net income. 

Separate Accounting – Forms C and N: 

If using the separate accounting method, don’t complete lines 5 through 9. An exempt organization engaged in a 
nonunitary business in and outside Wisconsin must determine the amount of income attributable to Wisconsin by 
separate accounting. The exempt organization uses Form C,                Wisconsin Allocation and Separate Accounting Data, 
to compute the amount attributable to Wisconsin by separate accounting and uses Form N, Wisconsin Nonappor-
tionable, Separately Accounted, and Separately Apportioned Income, to report the separate accounting amount. This 
is because the income determined under separate accounting from Form C, line 16 is entered on Form N, line 6. A 
nonunitary business is one in which the operations in Wisconsin aren’t dependent upon or contributory to the opera-
tions outside Wisconsin. Under separate accounting, the exempt organization must keep separate records of the 
sales, cost of sales, and expenses for the Wisconsin business. 

■ Line 11. Gross Tax – Enter 7.9% of the Wisconsin unrelated business taxable income reported on line 10. 

■ Line 12. Nonrefundable Credits – Enter any nonrefundable credits the exempt organization is claiming from 
Schedule CR. However, you may not offset these credits against the economic development surcharge. If you are 
claiming more than one credit, you must claim the credits in a specific order. To receive any credits, the taxpayer 
must include the appropriate credit computation schedules. See the Schedule CR instructions for details. 

If you are using credits carried forward from prior years or have current year unused credits that are being carried 
forward, complete and include a Schedule CF for each credit.   

To determine if the organization qualifies for any credits, see Publication 123,   Business Tax Incentives, which is 
available on the Department of Revenue’s web site at revenue.wi.gov/html/taxpubs.html. 

■ Line 13. Net Tax – Subtract line 12 from line 11.  If line 12 is greater than line 11, enter zero (0). 
 
Lines 14 Through 23 - Organizations Taxable as Trusts 

■ Line 14. Federal Unrelated Business Taxable Income – Enter the amount from federal Form 990-T, Part I, line 
11. However, if the trust is required to file Form 4720, enter the amount of federal unrelated business taxable income 
as computed in the supporting schedules to Form 4720. The amount on line 14 should be after applying the net 
operating loss deduction and special deductions.

 CAUTION: If any changes to the Internal Revenue Code or differences described earlier affect the computation of 
 federal unrelated business taxable income but don’t apply for Wisconsin purposes, account for the differences on 
 Parts 1 and 2 on page 3. 
                                                                                                                   
■ Line 15. Trust Additions – Federal unrelated business taxable income on Form 4T, line 14, may include items 
that aren’t deductible for Wisconsin tax purposes, or it may not include items that are taxable for Wisconsin tax 
purposes. Complete Part 1 on page 3 and enter the total to account for these differences. 

Instructions for how to complete Part 1 - Additions: 

• Line 1. Interest Income – Enter interest income, less related expenses, received on state and municipal obliga-
  tions that was excluded from federal unrelated business taxable income, except interest which is by law exempt 
  from Wisconsin taxation. Enter only the state or municipal interest that is considered unrelated business taxable 
  income. 
• Line 2. State Taxes – Enter the amount of taxes deducted from federal unrelated business taxable income under 
  IRC section 164. 
• Line 3. Capital Gains and Losses – If federal unrelated business taxable income includes capital gains or losses, 
  complete Wisconsin Schedule 2WD (Form 2) to determine if an adjustment is necessary to arrive at Wisconsin 
  unrelated business taxable income.  
• Line 4. Net Operating Loss Carryover – Enter the amount of any federal net operating loss carryover. 
• Lines 5. Related Entity Expenses – An exempt organization taxable as a trust must make an addition modification 
  to “add back” management fees and intangible, interest or rental expenses paid, accrued, or incurred to a related 
  entity. These expenses must generally also be disclosed on Schedule RT. See the Schedule RT instructions for 
  further details of the expenses required to be disclosed on Schedule RT and added back to income on Part 1. 

  After the trust makes this addition modification, the trust uses Part II of Schedule RT to determine if it is eligible 
  for a deduction for any of the amount added back. The trust then makes a subtraction modification on Part 2 in 
  the amount it is eligible to deduct. 
  If the trust is a partner, member, beneficiary, or shareholder of a pass-through entity, also include the amount of 
  modification included on line 22a of Schedule 3K-1; line 14a of Schedule 2K-1; and line 18a of Schedule 5K-1, 
  as applicable. 
• Line 6. Reserved for Future Use  
• Line 7. Transitional Adjustments – Enter any transitional adjustments required by sec. 71.05(13), Wis. Stats., 
  to account for differences between the federal and Wisconsin bases of changing basis assets (those subject to 
  depreciation or amortization). Include a schedule showing the computation of each transitional adjustment made. 
• Line 8. Credits Includable in Income – For certain credits, you must include the credit amount in your income.

    Internal Revenue Code. 
     
■ Line 17. Trust Subtractions – Federal unrelated business taxable income on Form 4T, line 14, may not include 
items that are deductible for Wisconsin tax purposes, or it may include items that aren’t taxable for Wisconsin pur-
poses. Complete Part 2 on page 3 and enter the total.  
 
Instructions for how to complete Part 2 - Subtractions: 

• Line 1. Interest Income – Enter interest and dividend income, less related expenses, received on obligations and 
  certain securities of the United States government that was included in federal unrelated business taxable income 
  and is exempt from state income taxation. 
• Line 2. Capital Gains and Losses – If federal unrelated business taxable income includes capital gains or losses, 
  complete Wisconsin Schedule 2WD (Form 2) to determine if an adjustment is necessary to arrive at Wisconsin 
  unrelated business taxable income. For example, an adjustment may be required because Wisconsin law allows 
  an exclusion of 30% of the net capital gain from assets held more than one year (60% on farm assets held more 
  than one year and on all farm assets acquired from a decedent). 
• Line 3. Net Operating Loss Carryforward – Enter the amount of any Wisconsin net operating loss carryforward.

• Line 4. Related Entity Expenses – An exempt organization taxable as a trust must make an addition modification 
  to “add back” management fees, intangible expenses, interest expenses, or rental expenses that are paid, accrued, 
  or incurred to a related entity if that interest was deducted from federal unrelated business taxable income. The 
  “addback” is reported on Part 1, line 5. After the exempt organization makes this addition modification, it completes 
  Part II of Schedule RT to determine if it is eligible for a deduction for any of the amount added back. The exempt 
  organization then makes a subtraction modification on Part 2, line 4, for the amount it is eligible to deduct. See the 
  Schedule RT instructions for details of the conditions necessary to claim this subtraction. 
  If the exempt organization is a partner, member, beneficiary, or shareholder of a pass-through entity, also include 
  the amount of modification included on line 22b of Schedule 3K-1, line 14b of Schedule 2K-1, and line 18b of 
  Schedule 5K-1, as applicable. 
• Line 6. Transitional Adjustments – Enter any transitional adjustment required by sec. 71.05(13), Wis. Stats., to 
  account for differences between the federal and Wisconsin bases of changing basis assets (those subject to de-
  preciation or amortization). Include a schedule showing the computation of each transitional adjustment.  
• Line 7. Other Subtractions –  Enter any amount not subject to Wisconsin taxation that was included in federal 
  unrelated business taxable income, or any deduction allowed for Wisconsin that wasn’t deducted federally (such 
  as development zones investment credit recaptured):  
  o  Include on line 6 any trust income that was included in federal unrelated business taxable income but not 
   sourced to Wisconsin. 
  o  Adjustments required as a result of changes made to the Internal Revenue Code which don't apply for Wis-
   consin.  Refer to the list of provisions of the Internal Revenue Code not adopted by Wisconsin for items that 
   may require adjustment.  
 
  o  Income received from the state of Wisconsin with money received from the coronavirus relief fund authorized 
   under 42 USC 801 to be used for any of the following purposes:                       
       o  Grants to small businesses                   o  Lodging industry grants 
       o  A farm support program                       o  Low-income home energy assistance 
       o  Broadband expansion                          o  A rental assistance program 
       o  Privately owned movie theater grants         o  Supplemental childcare grants 
       o  A nonprofit grant program                    o  A food insecurity initiative

       o  A cultural organization grant program        o  Wisconsin Eye 
       o  Music and performance venue grants 
    
  o  Income received in the form of a grant issued by the Wisconsin Economic Development Corporation during 
   and related to the COVID-19 pandemic under the ethnic minority emergency grant program. 
    
   Note: For Wisconsin, expenses paid for with these programs and deducted in the computation of federal ad-
   justed gross income are not required to be added back on the Wisconsin return. Income from these pro-
   grams is included in federal income according to sec. 61, IRC, unless an exception applies. Income from 
   these programs included in federal income should be excluded for Wisconsin by making a subtraction modifi-
   cation. For the description, use "Wisconsin COVID-19 Program Funds."

following year's estimated tax payments, if the refund has not been paid or applied elsewhere (for example, against 
a delinquent tax liability).  
 
An election to apply a refund to estimated tax may be changed to:

  • request payment of the refund, 
  • credit the refund against an amended return tax liability for any year, or 
  • credit the refund against a notice of amount due for any year. 
 
For individual and fiduciary income tax, notification of a change in election must occur on or before the due date 
of the final estimated tax installment payment (January 15, 2024, for a calendar-year filer). 
 
For corporation franchise and income tax, notification of a change in election must occur on or before the unextended 
due date of the following year's tax return or before the following year's tax return is filed, whichever is earlier.

Wisconsin Income of Multistate Organizations 

Who Must Use Apportionment 
Under the apportionment method, an exempt organization shows all income and deductions from unrelated trade or 
business activities for the organization as a whole and then assigns a part to Wisconsin according to a formula that 
determines Wisconsin unrelated business taxable income. 

An exempt organization engaged in unrelated trade or business activities in and outside Wisconsin is required to 
report a portion of its total unrelated business taxable income to Wisconsin using the apportionment method if its 
Wisconsin operations are a part of a unitary business, unless the department gives permission to use separate ac-
counting. To use the apportionment method, an exempt organization must have unrelated trade or business activity 
sufficient to create nexus in Wisconsin and at least one other state or foreign country. 

A unitary business is one that operates as a unit and can’t be segregated into independently operating divisions or 
branches. The operations are integrated, and each division or branch is dependent upon or contributory to the oper-
ation of the business as a whole. It isn’t necessary that each division or branch operating in Wisconsin contribute to 
the activities of all divisions or branches outside Wisconsin. 

To use the apportionment method, an exempt organization must have business activity sufficient to create nexus in 
Wisconsin and at least one other state or foreign country. “Nexus” means that an exempt organization’s business 
activity is of such a degree that the state or foreign country has jurisdiction to impose an income tax or franchise tax 
measured by net income.  

Under Public Law 86-272, a state can’t impose an income tax or franchise tax based on net income on an exempt 
organization selling tangible personal property if the organization’s only activity in the state is the solicitation of orders, 
which orders are approved outside the state and are filled by delivery from a point outside the state. 

What Is the Apportionment Percentage 

IC-102 (R. 11-23)                                       25

                                  2023 Wisconsin Form 4T Instructions 

For unitary, multistate businesses (except direct air carriers, air freight forwarders affiliated with a direct air carrier, 
motor carriers, railroads, pipeline companies, financial institutions, brokers-dealers, investment advisers, investment 
companies, underwriters, and telecommunications companies whose incomes are apportioned by special rules of 
the department), the apportionment percentage is determined by the ratio of Wisconsin sales to total company sales. 

For most companies, the apportionment percentage is computed on Schedule A-01. However, financial institutions, 
direct air carriers, air freight forwarders affiliated with a direct air carrier, motor carriers, railroads, pipeline companies, 
telecommunications companies, insurance companies, interstate brokers-dealers, investment advisors, investment 
companies, and underwriters, broadcasters, and interstate pipeline companies use alternative schedules:  

The apportionment schedules consist of the following: 

•  Schedule A-01, Wisconsin Single Sales Factor Apportionment Data for Nonspecialized Industries
•  Schedule A-02, Wisconsin Apportionment Percentage for Interstate Financial Institutions,
•  Schedule A-03, Wisconsin Apportionment Percentage for Interstate Motor Carriers,
•  Schedule A-04, Wisconsin Apportionment Percentage for Interstate Telecommunications Companies,
•  Schedule A-05, Wisconsin Premiums Factor for Insurance Companies,
•  Schedule A-06, Wisconsin Receipts Factor for Interstate Brokers-Dealers, Investment Advisors, Investment Com-
   panies, and Underwriters,
•  Schedule A-07, Wisconsin Apportionment Percentage for Interstate Air Carriers,
•  Schedule A-08, Wisconsin Apportionment Percentage for Broadcasters,
•  Schedule A-09, Wisconsin Apportionment Percentage for Interstate Railroads,
•  Schedule A-10, Wisconsin Apportionment Percentage for Interstate Pipeline Companies,     or
•  Schedule A-11, Wisconsin Apportionment Percentage for Interstate Air Freight Forwarders Affiliated with a Direct
   Air Carrier

What Is Nonapportionable Unrelated Business Taxable Income 

Nonapportionable income is that income which is allocable directly to a particular state. It includes income or loss 
derived from the sale of nonbusiness real or tangible personal property or from rentals and royalties from nonbusiness 
real or tangible personal property. This income is assigned to the state where the property is located. 

All income that is realized from the sale of or purchase and subsequent sale or redemption of lottery prizes if the 
winning tickets were originally bought in Wisconsin shall be allocated to Wisconsin. 

Except for income from lottery prizes described above, the intangible income of a personal holding company is non-
apportionable and is assigned to the state of incorporation. 

Total nonapportionable income (loss) is removed from total company net income before the apportionment percent-
age is applied. The Wisconsin nonapportionable income (loss) is then combined with the Wisconsin apportionable 
income to arrive at Wisconsin net income. 

Corporate Partners or LLC Members 

An exempt corporation that is a general or limited partner includes its share of the numerator and denominator of the 
partnership’s apportionment factors in the numerator and denominator of its apportionment factors. An exempt cor-
poration that is a member of a limited liability company (LLC) treated as a partnership for federal tax purposes in-
cludes its share of the numerator and denominator of the LLC’s apportionment factors in the numerator and denom-
inator of its apportionment factors. The exempt corporation should request a detailed breakdown of the partnership’s 
or LLC’s items and amounts to be included in the computation of its apportionment factors.  

Note: Income from a partnership or LLC may be nontaxable under the principles of the U.S. Supreme Court decision 
in Allied-Signal v. Director, Div. of Taxation, 504 U.S. 768 (1992), if the investment is passive and does not serve an 
operational function. In this case, the exempt corporation would not include its share of the partnership’s or LLC’s

                               2023 Wisconsin Form 4T Instructions 

apportionment factors in the numerator and denominator of its apportionment factors. 

Separate Accounting 

An exempt organization engaged in a nonunitary business in and outside Wisconsin must determine the amount of 
income attributable to Wisconsin by separate accounting. The exempt organization uses Form C, Separate Account-
ing Data, to compute the amount attributable to Wisconsin by separate accounting and uses Form N, Wisconsin 
Nonapportionable and Separately Apportioned Income, to report the separate accounting amount. This is because 
the income determined under separate accounting from Form C, line 16 is entered on Form N, line 6. A nonunitary 
business is one in which the operations in Wisconsin aren’t dependent upon or contributory to the operations outside 
Wisconsin. Under separate accounting, the exempt organization must keep separate records of the sales, cost of 
sales, and expenses for the Wisconsin business. 

A unitary business may use separate accounting only with the approval of the department. An application for such 
approval must set forth, in detail, the reasons why separate accounting will more clearly reflect the exempt organiza-
tion’s Wisconsin net income. It should be mailed to the Wisconsin Department of Revenue, Mail Stop 3-107, PO Box 
8906, Madison, WI 53708-8906 before the end of the taxable year for which the use of separate accounting is desired.
