For purposes of this subsection, each member of a combined group is doing business in this state if any member of the combined group is doing business in this state and that business relates to the combined group’s unitary business. Except as provided in par. (b), a taxpayer’s share of the business income apportionable to this state of each combined group of which it is a member shall be the product of the business income of the combined group as determined under sub. (4) and the taxpayer’s modified sales factor from the combined group, determined as follows: 1.

(1)#

For a member that is subject to apportionment under s. 71.25 (9), the numerator of the modified sales factor includes the member’s sales associated with the combined group’s unitary business in this state. Sales under s. 71.25 (9) (b) 2m. and 3. and (c) shall be included in the numerator of the modified sales factor if no member of the combined group is within the jurisdiction of the destination state for income or franchise tax purposes.

(2)#

For a member that is subject to apportionment using a receipts factor under the department’s rules pursuant to s. 71.25 (10), the numerator of the modified sales factor includes the member’s Wisconsin receipts associated with the combined group’s unitary business in this state, as provided by such rules.

(3)#

For a member that is subject to apportionment under s. 71.45 (3), the numerator of the modified sales factor includes the member’s premiums that are associated with the combined group’s unitary business in this state.

(4)#

The denominator of the modified sales factor shall include the denominator of the sales factor for each combined group member described in subd. 1., the denominator of the receipts factor for each combined group member described in subd. 2., and the denominator of the premiums factor for each combined group member described in subd. 3.

(5)#

For a member that is required under the department’s rules to use an apportionment factor or factors other than the sales factor, receipts factor, or premiums factor, the numerator of the modified sales factor for such member is its Wisconsin apportionment percentage on a separate entity basis based on the rules prescribed by the department, multiplied by the member’s total sales, as defined in s. 71.25 (9) (e) and (f). The denominator of the modified sales factor for such member is the member’s total sales as defined in s. 71.25 (9) (e) and (f).

(6)#

The numerator and denominator, described in subds. 1. to 5., shall include the sales, receipts, or premiums of pass-through entities that are owned directly or indirectly by a corporation in proportion to a ratio the numerator of which is the amount of the corporation’s distributive share of the pass-through entity’s unitary business income included in the income of the combined group under sub. (4) and the denominator of which is the amount of the pass-through entity’s total unitary business income.

(7)#

The modified sales factor shall exclude transactions between members of the same combined group.

(8)#

For purposes of determining the numerator of the modified sales factor or any apportionment factor or factors determined under par. (b), a taxpayer is considered to be within the jurisdiction for income or franchise tax purposes of any state in which any member of its combined group is within the jurisdiction for income or franchise tax purposes.
