(2)
Grantor trusts. The situs of income received by a trustee, which income, under the internal revenue code, is taxable to the grantor of the trust or to any person other than the trust, shall be determined as if such income had been actually received directly by such grantor or such other person, without the intervention of the trust.
(4)
Corporations engaged in business wholly within this state. For corporations engaged in business wholly within this state, all income is subject to, or included in the measure of, the Wisconsin income or franchise tax.

(6)
Allocation and separate accounting and apportionment formula. Corporations engaged in business within and without the state shall be taxed only on such income as is derived from business transacted and property located within the state. The amount of such income attributable to Wisconsin may be determined by an allocation and separate accounting thereof, when the business of such corporation within the state is not an integral part of a unitary business, but the department of revenue may permit an allocation and separate accounting in any case in which it is satisfied that the use of such method will properly reflect the income taxable by this state. In all cases in which allocation and separate accounting is not permissible, the determination shall be made in the following manner: for all businesses except air carriers, financial organizations, telecommunications companies, pipeline companies, public utilities, railroads, car line companies and corporations or associations that are subject to a tax on unrelated business income under s. 71.26 (1) (a) there shall first be deducted from the total net income of the taxpayer the part thereof (less related expenses, if any) that follows the situs of the property or the residence of the recipient. The remaining net income shall be apportioned to this state by use of the following:
(a)
For taxable years beginning before January 1, 2006, an apportionment fraction composed of a sales factor under sub. (9) representing 50 percent of the fraction, a property factor under sub. (7) representing 25 percent of the fraction, and a payroll factor under sub. (8) representing 25 percent of the fraction.
(b)
For taxable years beginning after December 31, 2005, and before January 1, 2007, an apportionment fraction composed of a sales factor under sub. (9) representing 60 percent of the fraction, a property factor under sub. (7) representing 20 percent of the fraction, and a payroll factor under sub. (8) representing 20 percent of the fraction.
(c)
For taxable years beginning after December 31, 2006, and before January 1, 2008, an apportionment fraction composed of a sales factor under sub. (9) representing 80 percent of the fraction, a property factor under sub. (7) representing 10 percent of the fraction, and a payroll factor under sub. (8) representing 10 percent of the fraction.
(d)
For taxable years beginning after December 31, 2007, an apportionment fraction composed of the sales factor under sub. (9).
(e)
For taxable years beginning after December 31, 2005, and before January 1, 2008, the apportionment fraction for the remaining net income of a financial organization shall include a sales factor that represents more than 50 percent of the apportionment fraction, as determined by rule by the department. For taxable years beginning after December 31, 2007, the apportionment fraction for the remaining net income of a financial organization is composed of a sales factor, as determined by rule by the department.
(6m)
Apportionment formula computation.
(a)
1.
For taxable years beginning before January 1, 2008, if both the numerator and the denominator of the sales factor under sub. (9) related to a taxpayer's remaining net income are zero, the sales factor under sub. (9) is eliminated from the apportionment formula to determine the taxpayer's remaining net income under sub. (6).
2.
For taxable years beginning after December 31, 2007, if both the numerator and the denominator of the sales factor under sub. (9) related to a taxpayer's remaining net income are zero, none of the taxpayer's remaining net income is apportioned to this state.
(b)
1.
For taxable years beginning before January 1, 2008, if the numerator of the sales factor under sub. (9) related to a taxpayer's remaining net income is a negative number and the denominator of the sales factor under sub. (9) related to a taxpayer's remaining net income is a positive number, a negative number, or zero, the sales factor under sub. (9) is zero.
2.
For taxable years beginning after December 31, 2007, if the numerator of the sales factor under sub. (9) related to a taxpayer's remaining net income is a negative number and the denominator of the sales factor under sub. (9) related to a taxpayer's remaining net income is a positive number, a negative number, or zero, none of the taxpayer's remaining net income is apportioned to this state.
(c)
1.
For taxable years beginning before January 1, 2008, if the numerator of the sales factor under sub. (9) related to a taxpayer's remaining net income is a positive number and the denominator of the sales factor under sub. (9) related to a taxpayer's remaining net income is zero or a negative number, the sales factor under sub. (9) is one.
2.
For taxable years beginning after December 31, 2007, if the numerator of the sales factor under sub. (9) related to a taxpayer's remaining net income is a positive number and the denominator of the sales factor under sub. (9) related to a taxpayer's remaining net income is zero or a negative number, all of the taxpayer's remaining net income is apportioned to this state.
(7)
Property factor. For purposes of sub. (6) and for taxable years beginning before January 1, 2008:
(a)
The property factor is a fraction, the numerator of which is the average value of the taxpayer's real and tangible personal property owned or rented and used in this state during the tax period and the denominator of which is the average value of all the taxpayer's real and tangible personal property owned or rented and used during the tax period. Cash on hand or in the bank, shares of stock, notes, bonds, accounts receivable, or other evidence of indebtedness, special privileges, franchises, goodwill, or property the income of which is not taxable or is separately allocated, shall not be considered tangible property nor included in the apportionment.
(b)
Property used in the production of nonapportionable income or losses shall be excluded from the numerator and denominator of the property factor. Property used in the production of both apportionable and nonapportionable income or losses shall be partially excluded from the numerator and denominator of the property factor so as to exclude, as near as possible, the portion of such property producing the nonapportionable income or loss.
(c)
Property owned by the taxpayer is valued at its original cost. Property rented by the taxpayer is valued at 8 times the net annual rental. Net annual rental is the annual rental paid by the taxpayer less any annual rental received by the taxpayer from sub-rentals.
(d)
The average value of property shall be determined by averaging the values at the beginning and ending of the tax period but the secretary of revenue may require the averaging of monthly values during the tax period if reasonably required to reflect properly the average value of the taxpayer's property.
(8)
Payroll factor. For purposes of sub. (6) and for taxable years beginning before January 1, 2008:
(a)
The payroll factor is a fraction, the numerator of which is the total amount paid in this state during the tax period by the taxpayer for compensation, and the denominator of which is the total compensation paid everywhere during the tax period.
(b)
Compensation is paid in this state if:
1.
The individual's service is performed entirely within this state;
2.
The individual's service is performed within and without this state, but the service performed without this state is incidental to the individual's service within this state;
3.
A portion of the service is performed within this state and the base of operations of the individual is in this state;
4.
A portion of the service is performed within this state and, if there is no base of operations, the place from which the individual's service is directed or controlled is in this state;
5.
A portion of the service is performed within this state and neither the base of operations of the individual nor the place from which the service is directed or controlled is in any state in which some part of the service is performed, but the individual's residence is in this state; or
6.
The individual is neither a resident of nor performs services in this state but is directed or controlled from an office in this state and returns to this state periodically for business purposes and the state in which the individual resides does not have jurisdiction to impose income or franchise taxes on the employer.
(c)
Compensation related to the operation, maintenance, protection or supervision of property used in the production of both apportionable and nonapportionable income or losses shall be partially excluded from the numerator and denominator of the payroll factor so as to exclude, as near as possible, the portion of pay related to the operation, maintenance, protection and supervision of property used in the production of nonapportionable income.
(d)
In this subsection, compensation includes deductible management or service fees paid to a related corporation as consideration for the performance of personal services, and the situs of those fees is in this state if the services fulfill one of the requirements under par. (b). The recipient of the fees may not include the compensation paid to its employees with respect to personal services in either the numerator or denominator of its payroll factor. Except for management or service fees, payments made to a related corporation, an independent contractor or any person not properly classifiable as an employee are excluded. In this paragraph, “related corporation" means a corporation which is part of a controlled group as defined in section 267 (f) (1) of the internal revenue code.
(e)
If the company has no employees and pays no management or service fees or the department determines that employees are not a substantial income-producing factor and that the management or service fees paid are insubstantial, the department may order or permit the elimination of the payroll factor.
(9)
Sales factor. For purposes of sub. (5):
(a)
The sales factor is a fraction, the numerator of which is the total sales of the taxpayer in this state during the tax period, and the denominator of which is the total sales of the taxpayer everywhere during the tax period. For sales of tangible personal property, the numerator of the sales factor is the sales of the taxpayer during the tax period under par. (b) 1. and 2. plus 100 percent of the sales of the taxpayer during the tax period under pars. (b) 2m. and 3. and (c). For purposes of applying pars. (b) 2m. and 3. and (c), if a taxpayer is within another state's jurisdiction for income or franchise tax purposes for any part of the taxable year, it is considered to be within that state's jurisdiction for income or franchise tax purposes for the entire taxable year.
(b)
Sales of tangible personal property are in this state if any of the following occur:
1.
The property is delivered or shipped to a purchaser, other than the federal government, within this state regardless of the f.o.b. point or other conditions of the sale.

(df)
1.
Gross receipts from the use of computer software are in this state if the purchaser or licensee uses the computer software at a location in this state.
2.
Computer software is used at a location in this state if the purchaser or licensee uses the computer software in the regular course of business operations in this state, for personal use in this state, or if the purchaser or licensee is an individual whose domicile is in this state. If the purchaser or licensee uses the computer software in more than one state, the gross receipts shall be divided among those states having jurisdiction to impose an income tax on the taxpayer in proportion to the use of the computer software in those states. To determine computer software use in this state, the department may consider the number of users in each state where the computer software is used, the number of site licenses or workstations in this state, and any other factors that reflect the use of computer software in this state.

The net business income of railroads, car line companies, pipeline companies, financial organizations, telecommunications companies, air carriers, and public utilities requiring apportionment shall be apportioned pursuant to rules of the department of revenue, but the income taxed is limited to the income derived from business transacted and property located within the state.
(11)
Department may waive factor. Where, in the case of any corporation engaged in business in and outside of this state and required to apportion its income as provided in sub. (6), it shall be shown to the satisfaction of the department of revenue that the use of any one of the 3 factors provided in sub. (6) gives an unreasonable or inequitable final average ratio because of the fact that such corporation does not employ, to any appreciable extent in its trade or business in producing the income taxed, the factors made use of in obtaining such ratio, this factor may, with the approval of the department of revenue, be omitted in obtaining the final average ratio which is to be applied to the remaining net income. This subsection does not apply to taxable years beginning after December 31, 2007.

(a)
Upon request by a corporation on or before January 1, 2000, the department of revenue may authorize a corporation or a subsidiary thereof to use or continue to use a different method of apportioning its income to this state for purposes of this subchapter, and may specify the method of apportionment that the corporation or subsidiary shall use. This paragraph is to be used exclusively in the event of a corporate restructuring that would result in an unfair representation of the degree of business activity in this state. In no instance may the alternative method proposed under the new corporate structure result in less franchise or income tax revenue to the state than the current corporate structure is liable for, given the same overall level of sales, payroll and property.
(b)
Before the department of revenue grants permission to any corporation to use an alternative method of allocation under par. (a), the department of revenue shall promulgate rules that specify in more detail the circumstances in which that authority may be granted and the kinds of alternative methods that the department may authorize.
(c)
At least 14 days before giving final approval to an alternative method of apportionment under par. (a), the department of revenue shall submit the proposed alternative method of apportionment to the cochairpersons of the joint committee for review of administrative rules, together with a description of the proposed alternative and the reasons for the proposed alternative. If, within 14 days after receipt of the proposed alternative method, the cochairpersons of the joint committee for review of administrative rules do not notify the department of revenue that the proposed alternative must be promulgated as an administrative rule in order to be used, the department of revenue may give final approval to the proposed method without promulgating an administrative rule. If the cochairpersons of the joint committee for review of administrative rules notify the department of revenue within 14 days after receipt of the proposed alternative that the proposed alternative must be promulgated as an administrative rule, the proposed alternative may not be used until it is promulgated as an administrative rule under ch. 227.
(15)
Partnerships and limited liability companies.
(a)
A general or limited partner's share of the numerator and denominator of a partnership's apportionment factors under this section are included in the numerator and denominator of the general or limited partner's apportionment factors under this section.
(b)
If a limited liability company is treated as a partnership, for federal tax purposes, a member's share of the numerator and denominator of a limited liability company's apportionment factors under this section are included in the numerator and denominator of the member's apportionment factors under this section.
(16)

For purposes of the apportionment of any income under this section, the disaster relief work, as defined in s. 323.12 (5) (a) 3., of an out-of-state business, as defined in s. 323.12 (5) (a) 6., shall not increase the amount of income apportioned to this state. For purposes of sub. (7), any property brought temporarily into this state by an out-of-state business in connection with performing disaster relief work is not considered property located in this state. For purposes of sub. (8), compensation paid to out-of-state employees, as defined in s. 323.12 (5) (a) 7., who are performing disaster relief work is not considered compensation paid in this state. For purposes of sub. (9), gross receipts from the sale of property or services as part of performing any disaster relief work are not considered gross receipts from sales received in this state.
History: 1987 a. 312; 1987 a. 411 ss. 57, 62, 117 to 123; 1989 a. 31; 1991 a. 39, 269; 1993 a. 112; 1997 a. 299; 1999 a. 9; 2001 a. 16; 2003 a. 37; 2005 a. 25; 2009 a. 2, 28, 276; 2015 a. 84, 216; 2017 a. 59; 2021 a. 239.
Under sub. (6), it is within the Department of Revenue's discretion to decide whether to permit a multistate business to deviate from the apportionment method. Nelson Brothers Furniture Corp. v. DOR, 152 Wis. 2d 746, 449 N.W.2d 328 (Ct. App. 1989).
Discussing subjecting an entity's income to apportionment when the entity's operations constitute a “unitary business" under sub. (6). Chilstrom Erecting Corp. v. DOR, 174 Wis. 2d 517, 497 N.W.2d 785 (Ct. App. 1993).
A corporation's investment income that served an “operational" function and was not unrelated to corporate functions within the state was subject to apportionment. Port Affiliates, Inc. v. DOR, 190 Wis. 2d 271, 526 N.W.2d 806 (Ct. App. 1994).
Sub. (9) (df) is limited to a “licensee" who uses software in Wisconsin. The provision makes no reference to use of the computer software in this state by a “sublicensee." In this case, when the defendant taxpayer received royalties from licensing its software to businesses that were not located in this state and that manufactured or assembled computers that incorporated the defendant's software but whose products were used in this state under a sublicense, the royalties were not considered in calculating the defendant's franchise tax liability under this section. The software end-users were not licensees of the defendant. DOR v. Microsoft Corp., 2019 WI App 62, 389 Wis. 2d 350, 936 N.W.2d 160, 18-2024.
