                   Wisconsin Subtractions from Federal Income

Purpose of Schedule 4W 

Corporations complete Schedule 4W to report subtraction modifications that are needed to account for differences 
between taxable income under Wisconsin law and under federal law. The corporation files Schedule  4W with its 
Wisconsin Form 4.  

Line-by-Line Instructions 

■ Line 1. Wisconsin Subtraction Modification for Dividends – Enter the total from line 4 of Schedule 4Y. See the 
Schedule 4Y instructions for an explanation of dividends that are eligible for the subtraction.  

■ Line 2. Related Entity Expenses –  If the corporation made an addition modification for related entity expenses on 
Schedule 4V, line 3, this is where you report the amount that qualifies for a deduction. Enter the amount of the 
expenses from Schedule 4V, line 3, that are deductible using the criteria described in Conditions for Deducting Re-
lated Entity Expenses, below.  

For corporations that are partners, members, or beneficiaries of pass-through entities, also include the amount of 
allowable related entity expense reported on line 22b of Schedule 3K-1 and on line 14b of Schedule 2K-1, as appli-
cable. 

Conditions for Deducting Related Entity Expenses. Section 71.80(23)(a)3., Wis. Stats., provides that a   related 
entity expense that was added back on Schedule 4V, line 3, qualifies for a deduction if all the following conditions are 
met: 
• The primary motivation for the transaction was one or more business purposes other than the avoidance or 
  reduction of state income or franchise taxes; 
• The transaction changed the economic position of the taxpayer in a meaningful way apart from tax effects; and 
• The expenses were paid, accrued, or incurred using terms that reflect an arm’s length relationship. 

Factors that may indicate that the expense does not qualify for a deduction include the following:   

• There was no actual transfer of funds from the taxpayer to the related entity, or the funds were substantially 
  returned to the taxpayer, either directly or indirectly. 
• If the transaction was entered on the advice of a tax advisor, the advisor’s fee was determined by reference to 
  the tax savings. 
• The related entity does not regularly engage in similar transactions with unrelated parties on terms substantially 
  similar to those of the subject transaction. 
• The transaction was not entered into at terms comparable to arm’s length as determined by Treas. Reg. 1.482-
  1(b). 
• There was no realistic expectation of profit from the transaction apart from the tax benefits. 
• The transaction resulted in improper matching of income and expenses. 
• An expense for the transaction was accrued under FIN 48. 

The statutes (sec. 71.80(23)(a)1. and 2., Wis. Stats.) provide some additional conditions under which a related entity 
expense may qualify for a deduction, subject to some important exceptions. Those conditions are: 
• If the expense was paid to a related entity that is merely acting as a conduit between the taxpayer and an unre-
  lated entity, or

                                      2024 Schedule 4W Instructions 
 
• If the related entity was subject to a tax measured by net income or receipts and the net income or receipts of 
  the transaction were included in its tax base. 

More Information on Related Entity Expenses. For more information on the deductibility of related entity expenses, 
see the Schedule RT instructions. Even if you weren’t required to file Schedule RT for the expenses you added back 
on Schedule 4V, the instructions to Schedule RT provide helpful information regarding deductibility of related entity 
expenses. 

■ Line 3. Income from Related Entities Whose Expenses Were Disallowed – If the corporation has income from 
a related entity which paid, accrued, or incurred expenses to the corporation, and that related entity could not deduct 
those expenses according to the instructions for line 2, the corporation may subtract the corresponding income from 
its taxable income. 

To claim a subtraction on line 3, the corporation must obtain Schedule RT-1 from the related entity and include 
Schedule RT-1 with Schedule 4W. See the Schedule RT-1 instructions for further details. 

■ Line 4. Subpart F, and Section 965(a) Income –  

• Enter income from controlled foreign corporations under Subpart F of the Internal Revenue Code as reported

• Do not include Previously Taxed Income (PTI) required to be reported on Form 1120, Reconciliation of Net In-
  come (Loss) per Income Statement of Includible Corporations With Taxable Income per Return.  An addition 
  adjustment for PTI should not be netted against a Subpart F income subtraction.  Report PTI as an addition on 
  Schedule 4V, line 4. 
• Enter section 965(a) inclusion as reported on Form 1120. 

Line 5. Global intangible low-taxed income (GILTI) -Enter GILTI as reported on Form 1120, Schedule C, line 17, 
column (a). 

■ Line 6. Foreign Dividend Gross-Up – Enter foreign dividend gross-up reported on Form 1120, Schedule C, line 
18, column (a).  

■ Line 7. Nontaxable Income – Enter nontaxable income included in computing federal taxable income. Include a 
schedule with your return showing the payers and amounts of nontaxable income and explaining why that income 
isn’t taxable. 

Interest, dividends, and capital gains from the disposition of intangible assets are nontaxable if both of the following 
are true: 
• The operations of the payer are not unitary with those of the payee, and 
• The payer and payee are not related as parent company and subsidiary or affiliates and the investment activity 
  from which the income is received is not an integral part of a unitary business. 

Income may also 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. 

For corporations subject to the Wisconsin income tax rather than the franchise tax, nontaxable income also includes 
interest on United States government obligations. 

Franchise tax applies to: 

•  All domestic corporations (those organized under Wisconsin law), and 

•  Foreign corporations (those not organized under Wisconsin law) doing business in Wisconsin or buying or selling 
  lottery prizes if the winning tickets were originally bought in Wisconsin, except where taxation is exempted by 
  statute or barred by federal law.

                                           2024 Schedule 4W Instructions 
 
The tax rate is 7.9%. Income from obligations of the United States government and its instrumentalities is included in 
income under the franchise tax law. 

Income tax applies only to foreign corporations which are not subject to the franchise tax and which own property in 
Wisconsin or whose business in Wisconsin is exclusively in foreign or interstate commerce. The tax rate is 7.9%. 
Income from obligations of the United States government and its instrumentalities is not included in income under the 
income tax law. 

 CAUTION:         Expenses  related  to  nontaxable  income  aren’t  deductible  and  must  be  added  to  federal  taxable 
 income on Schedule 4V, line 5.

Internal Revenue Code in effect for Wisconsin purposes. For further information about the differences between fed-
eral and Wisconsin basis and depreciation, see the section titled Conformity with Internal Revenue Code and Excep-
tions in the Form 4 instructions, as applicable.

   conditions are met: 
    
     •            In a previous year, the corporation deferred paying tax on a capital gain by investing in a Wisconsin 
                  QOF.

                  required for taxable years beginning prior to January 1, 2020.
