Every corporation subject to a tax on unrelated business income under s. 71.26 (1) (a), if that corporation is required to file for federal income tax purposes, shall furnish to the department a true and accurate statement on or before the date on which the corporation is required to file for federal income tax purposes, not including any extension, under the Internal Revenue Code. The requirements about manner, form, and subscription under sub. (1) apply to statements under this subsection.

71.24(3) (3) Inactive corporations. Whenever a corporation has been completely inactive for an entire taxable year, in lieu of filing the statements and information otherwise required by this section, it may file a declaration, on a form to be provided by the department, subscribed by its president, if a resident of this state, and, if not a resident, then by another officer residing in this state, attesting to such inactivity. Such declaration must be filed prior to the otherwise due date for its Wisconsin return for such taxable year. Thereafter the corporation need not file such statements or information for any subsequent year unless specifically requested to do so by the department or unless in a subsequent year the corporation has been activated or reactivated.

71.24(4) (4) Filing returns by receiver, trustee in bankruptcy or assignee. If a receiver, trustee in bankruptcy or assignee, by order of a court, by operation of law or otherwise, has possession of all or substantially all of the property or business of a corporation, whether or not such property or business is being operated, such receiver, trustee or assignee shall make the return of income for such corporation in the manner and form that corporations are required to make such returns.

71.24(5) (5) Department may require filing. Nothing contained in this section shall preclude the department from requiring any corporation to file a return when in the judgment of the department a return should be filed.

71.24(6) (6) Changing reporting period.

71.24(6)(a) (a) Corporations may not change their basis of reporting from a calendar year to a fiscal year, from a fiscal year to a calendar year, or from one fiscal year to another without first obtaining the approval of the department of revenue unless the internal revenue service has approved the change or unless the change, including a change to a short taxable year, is required by the internal revenue code before approval by the internal revenue service and the reason for the change is explained in the first return filed for the new taxable year. Corporations that make changes on the basis of federal changes shall submit a copy of the internal revenue service’s notice of approval, if prior federal approval, other than expeditious approval, was required, or requirement, if prior federal approval was not required or if the corporation qualifies for expeditious approval, to the department of revenue along with the return for the first taxable year for which the change applies.

71.24(6)(b) (b) If a corporation changes its basis of reporting from a calendar year to a fiscal year a separate return shall be made for the period between the close of the last calendar year and the date designated as the close of the fiscal year. If the change is from a fiscal year to a calendar year, a separate return shall be made for the period between the close of the last fiscal year and the following December 31. If the change is from one fiscal year to another fiscal year a separate return shall be made for the period between the close of the former fiscal year and the date designated as the close of the new fiscal year. In no case shall a separate income or franchise tax return be made for a period of more than 12 months.

71.24(6)(c) (c) If a separate corporation income tax return is made for a fractional part of a year for federal income tax purposes, the corporation shall file a separate Wisconsin income or franchise tax return for that fractional year. The income shall be computed and reported on the basis of the period for which the separate return is made, and that fractional part of a year shall constitute a taxable year, except that if a corporation terminates, under section 1362 (d) (1) or (2) of the internal revenue code, its election to be treated as an S corporation for federal income tax purposes the corporation may allocate its items of income, loss or deduction between its short taxable year as a tax-option corporation and its short taxable year as a nontax-option corporation according to the method under section 1362 (e) (2) of the internal revenue code.

71.24(6)(d) (d) If a separate income [or franchise] tax return is made for a short period under par. (b) on account of a change in the taxable year, the net income for such short period shall be placed on an annual basis using the method applicable for federal income taxes under section 443 (b) (1) of the internal revenue code.

71.24(7) (7) Extensions.

71.24(7)(a) (a) In the case of a corporation required to file a return, the department of revenue shall allow an automatic extension of 7 months or until the original due date of the corporation’s corresponding federal return, whichever is later. Any extension of time granted by law or by the internal revenue service for the filing of corresponding federal returns shall extend the time for filing under this subchapter to 30 days after the federal due date if the corporation reports the extension in the manner specified by the department on the return. Except for payments of estimated taxes, income or franchise taxes payable upon the filing of the tax return shall not become delinquent during such extension period, but shall, except as provided in par. (b), be subject to interest at the rate of 12 percent per year during such period.

71.24(7)(b) (b) For taxable years beginning after December 31, 2008, for persons who qualify for a federal extension of time to file under 26 USC 7508A due to a presidentially declared disaster or terroristic or military action, income or franchise taxes payable upon the filing of the tax return are not subject to interest as otherwise provided under par. (a).

71.25(6) (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.

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:

71.25(6)(a) (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.

71.25(6)(b) (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.

71.25(6)(c) (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.

71.25(6)(d) (d) For taxable years beginning after December 31, 2007, an apportionment fraction composed of the sales factor under sub. (9).

71.25(6)(e) (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.

71.25(6m)(a) (a)

71.25(6m)(a)1. 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).

71.25(6m)(a)2. 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.

71.25(6m)(b) (b)

71.25(6m)(b)1. 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.

71.25(6m)(b)2. 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.

71.25(6m)(c) (c)

71.25(6m)(c)1. 1. For taxable years beginning before January 1, 2008, if the numerator of the sales factor under sub.

71.25(6m)(c)2. 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.

71.25(7) (7) Property factor. For purposes of sub. (6) and for taxable years beginning before January 1, 2008:

71.25(7)(a) (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.

71.25(7)(b) (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.

71.25(7)(c) (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.

71.25(7)(d) (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.

71.25(8) (8) Payroll factor. For purposes of sub. (6) and for taxable years beginning before January 1, 2008:

71.25(8)(a) (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.

71.25(8)(b) (b) Compensation is paid in this state if:

71.25(8)(b)1. 1. The individual’s service is performed entirely within this state;

71.25(8)(b)2. 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;

71.25(8)(b)3. 3. A portion of the service is performed within this state and the base of operations of the individual is in this state;

71.25(8)(b)4. 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;

71.25(8)(b)5. 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

71.25(8)(b)6. 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.

71.25(8)(c) (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.

71.25(8)(d) (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.

71.25(8)(e) (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.

71.25(9) (9) Sales factor. For purposes of sub. (5):

71.25(9)(a) (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.

71.25(9)(b) (b) Sales of tangible personal property are in this state if any of the following occur:

71.25(9)(b)1. 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.
