Tax 2.61(9)(g)3.
3. If an insurance company is a combined group member and its tax liability measured by its total Wisconsin net income as provided in sub.
(5), including any net business loss carryforwards available from other combined group members, exceeds two percent of its gross premiums as defined in s.
76.62, Stats., plus 7.9 percent of the income described in sub.
(5) (f), its tax liability shall be limited to two percent of the gross premiums plus 7.9 percent of the income described in sub.
(5) (f). If the insurance company's tax liability is limited in this manner, its business loss carryforwards may not be shared with any other combined group members, and if the group is otherwise sharing loss carryforwards, loss carryforwards may not be assigned to the insurance company.
Tax 2.61(9)(h)1.1. Although a combined group member is entitled to the benefit of a net business loss carryforward, the member may elect not to use a portion or any of the available net business loss carryforward for a taxable year. This election does not reduce the amount of carryforward available for the following taxable year nor suspend the carryforward period provided in ss.
71.26 (4) and
71.45 (4), Stats.
Tax 2.61(9)(h)2.
2. A combined group member may also elect not to share a portion or any of its sharable net business loss carryforward with other combined group members. However, if the corporation shares any part of its sharable net business loss carryforward, the shared amount shall be divided among all members in the manner prescribed in this subsection, except as otherwise provided in pars.
(d),
(e) 1., and
(g) 3. A combined group member's election under this subdivision is effective only for the taxable year in which the election is made and shall have no effect on the member's ability to share net business loss carryforwards in future taxable years.
Tax 2.61(9)(i)1.1. Notwithstanding the provisions of this subsection, the total amount of net business loss carryforward that may be used by a combined group member or shared with other combined group members for a taxable year is limited by section
382 of the Internal Revenue Code as provided in s.
71.26 (3) (n), Stats. Section
382 of the Internal Revenue Code shall be applied without regard to the federal consolidated return regulations under section
1502 of the Internal Revenue Code.
Tax 2.61(9)(i)2.
2. If a combined group member is acquired by another combined group member, section
381 of the Internal Revenue Code controls whether the acquiring corporation may succeed to the target corporation's net business loss carryforwards. Wisconsin follows section
381 of the Internal Revenue Code, but modifies it in s.
71.26 (3) (n), Stats., so that it applies to Wisconsin net business loss carryforwards instead of federal net operating loss carryovers. If the acquirer succeeds to the target corporation's net business loss carryforwards, the target corporation's carryforwards shall be treated as originally incurred by the acquiring corporation and shall maintain their character as sharable or non-sharable.
Tax 2.61(9)(i)3.
3. The separate return limitation year provisions of the federal regulations under section
1502 of the Internal Revenue Code do not apply to net business loss carryforwards. The provisions of this subsection apply in place of these limitations.
Tax 2.61(10)
(10) Credits. A credit is an attribute of the separate corporation rather than of the combined group, and credits are computed for each corporation separately. However, s.
71.255 (6) (c), Stats., provides that a combined group member may share all or a portion of its research credits with the other members of the combined group. For purposes of this subsection, the term “research credit" means only the research expense credit under ss.
71.28 (4) or
71.47 (4), Stats., and the research facilities credit under ss.
71.28 (5) or
71.47 (5), Stats. This subsection explains how credits are computed and applied as well as the special rules that apply to research credits.
Tax 2.61(10)(a)
(a) Nonrefundable credits other than research credits. A combined group member's nonrefundable credits other than research credits, including carryforwards of those credits, may only be used by that combined group member to offset the tax liability attributable to its own taxable income as computed under sub.
(5).
Tax 2.61(10)(b)
(b) Refundable credits. Any refundable credits computed by a combined group member shall be claimed on the combined return and refunded to the designated agent to the extent not used to offset the total tax liability reported on the combined return.
Tax 2.61(10)(c)
(c) Sharing of research credits. If a combined group member computes a research credit, or has a carryforward of a research credit, the member may share a portion or all of the credit with the other members. For purposes of determining the sharable amount, the provisions of sub.
(9) (e) and
(f) apply to available research credits in the same manner as they apply to net business loss carryforwards. Research credit carryforwards incurred in taxable years beginning before January 1, 2009 are sharable to the extent the corporation with the credits would have been a member of the combined group had s.
71.255, Stats., been in effect and required combined reporting in those years. The method of sharing these credits is as follows:
Tax 2.61(10)(c)1.
1. Each combined group member shall first apply its total available credits, including its research credits, against its gross tax liability, if any, including its tax liability attributable to separate entity items. A combined group member's available credits shall be considered used against its tax liability from separate entity items before its tax liability from its share of combined unitary income. Available credits shall be used in the order specified in s.
71.30 (3), Stats. A combined group member may elect to apply a carryforward of a research credit before applying the research credit computed for the current taxable year.
Tax 2.61(10)(c)2.
2. Each member shall then separate any remaining available research credit into the sharable and non-sharable amount, as applicable. The ordering rules provided in sub.
(9) (c), relating to net business loss carryforwards, also apply to research credit carryforwards. The sharable research credits for each combined group member shall then be aggregated, except that any combined group member that elects not to share its sharable amount may exclude some or all of its sharable amount from the aggregate sharable amount.
Tax 2.61(10)(c)3.
3. The sharable amount shall be assigned to each combined group member in proportion to its tax liability from its share of combined unitary income. The sharable amount may only be assigned to a member to the extent the member's tax liability from combined unitary income has not already been offset by other credits and carryforwards applied by that member under subd.
1. An amount may not be assigned to a combined group member whose tax liability from combined unitary income has been fully offset by other credits.
Tax 2.61(10)(c)4.
4. Any remaining sharable amount remains an attribute of the corporation that originally generated the credit. The aggregate sharable amount used under subd.
3. shall be considered used proportionately from the sharable research credits of the corporations which contributed to the aggregate sharable amount.
Tax 2.61 Note
Example: Combined Group FGH consists of Member F, Member G, and Member H. F, G, and H have the following amounts in 2010:
-
See PDF for table 
Tax 2.61 Note
Assume all of the research expense credit carryforward is sharable. The aggregate sharable amount is $25,000 (= $15,000 + $10,000). This amount may be assigned to H to the extent of its tax liability from its share of the combined unitary income after applying its own credits. After H applies its own credits, the remaining tax liability from combined unitary income is $5,000 (= ($17,000) + $2,000 + $20,000; its $17,000 economic development credit is applied against tax liability from separate entity items before tax liability from combined unitary items). Since this amount is less than the aggregate sharable amount, the entire remainder of H's tax liability from combined unitary income ($5,000) is offset by the aggregate sharable amount.
Tax 2.61 Note
After the aggregate sharable amount is applied, the remaining aggregate sharable amount is $20,000 (= $25,000 - $5,000). Since the remaining sharable amount remains an attribute of the corporation that originally generated the credit, at the end of 2010, F would have $12,000 (= $20,000 x ($15,000 / $25,000)) in remaining research credit carryforward, and G would have $8,000 (= $20,000 x ($10,000 / $25,000)) in remaining research credit carryforward.
Tax 2.61(10)(c)5.
5. The provisions of sub.
(9) (h), as they relate to elections applicable to net business loss carryforwards, apply also to available research credits under this paragraph.
Tax 2.61(10)(d)
(d) Exception for funded research. If a combined group member incurs expenses that are otherwise qualified research expenses under section
41(d) of the Internal Revenue Code but for the fact that the research is funded by another combined group member, the expenses shall be considered qualified research expenses of the combined group member performing the research, and the reimbursement from the combined group member funding the research may not be considered a qualified research expense of the funding member. Regardless of where the funding member is located, the research must be performed in this state to qualify for the research credit for Wisconsin purposes.
Tax 2.61 Note
Example: Combined Group AB consists of Member A and Member B. In Year 1, B performs research that would be “qualified research" under section
41(d) of the Internal Revenue Code, except for the fact that A and B have entered into a contract where A provides funding for all of B's research at a markup of 10%. Neither A nor B perform any other research. During Year 1, A paid B $220,000 for research services, all of which would be “qualified research" for B if the research were not funded by A. On AB's Year 1 combined return, B may include $200,000 of qualified research expenses (= $220,000 - $20,000 markup) in its computation of the research credit. However, A may not compute any research credit. Since A and B are members of the same combined group, the funding arrangement between A and B is ignored for purposes of computing the research credit.
Tax 2.61(10)(e)
(e) Applicability of Internal Revenue Code. The provisions of sub.
(9) (i), as they relate to net business loss carryforwards, also apply to carryforwards of credits under this subsection.

Tax 2.62(1)(1)
Scope. Section
71.255 (2) (a), Stats., provides that a corporation engaged in a unitary business with one or more other corporations in the same commonly controlled group is generally required to determine its share of income from that unitary business using a combined report. Section
71.255 (1) (n), Stats., defines “unitary business." The purpose of this section is to provide further interpretation of the meaning of “unitary business."
Tax 2.62(2)
(2) General. A unitary business is a single, commonly controlled economic enterprise for which the components of the enterprise are sufficiently interdependent, integrated, and interrelated through their activities to such a degree that if the enterprise is doing business both within and outside a state, the state is permitted under the U. S. Constitution to tax a fairly apportioned share of the total net income of the enterprise.
Tax 2.62(2)(a)
(a) Commonly controlled. A unitary business may consist of a single entity or a group of two or more related entities, including corporations, tax-option corporations, partnerships, limited liability companies, sole proprietorships, estates, and trusts. A group of related entities may satisfy the commonly controlled requirement of a unitary business if they are related in any of the following ways:
Tax 2.62(2)(a)1.
1. The entities are related under the provisions of section
267 of the Internal Revenue Code which disallow losses on sales between related persons. By reference, this includes the rules in section
707(b) of the Internal Revenue Code, relating to partnerships.
Tax 2.62(2)(a)2.
2. The entities are related under section
1563 of the Internal Revenue Code, which defines a “controlled group of corporations" for federal income tax purposes.
Tax 2.62(2)(a)3.
3. The entities are corporations in the same “commonly controlled group" for Wisconsin purposes. “Commonly controlled group" has the meaning given in s.
71.255 (1) (c), Stats., as further interpreted by s.
Tax 2.61 (3).
Tax 2.62(2)(b)
(b) Components of enterprise. The components of a commonly controlled economic enterprise may consist either of divisions of a single entity or of multiple entities, or both. For purposes of this section, the term “participants" is used to describe these components of an economic enterprise.
Tax 2.62(2)(c)
(c) Sufficiently interdependent, integrated, and interrelated. Tax 2.62(2)(c)1.1. In general, the participants in a commonly controlled economic enterprise are considered a unitary business if their activities generate a synergy and mutual benefit that produces a sharing or exchange of value among them and a significant flow of value to the separate parts. Subsection
(3) presents indicators that sharing or exchange and flow of value are present.
Tax 2.62(2)(c)2.
2. The participants in a commonly controlled economic enterprise may also be considered a unitary business if there is unity of operation and use, as further explained in sub.
(4).
Tax 2.62(2)(c)3.
3. Under s.
71.255 (1) (n), Stats., the definition of “unitary business" shall be construed to the broadest extent permitted by the U.S. Constitution. Thus, case law provides additional guidance to determine whether a unitary business exists. Subsection
(5) presents factors that have been considered by the U.S. Supreme Court to be determinative of a unitary business.
Tax 2.62(2)(d)
(d) Fairly apportioned. If a unitary business has nexus in Wisconsin and is doing business both within and outside Wisconsin, an apportioned share of the unitary business's net income is taxable by Wisconsin under the rules of this paragraph. If a unitary business is doing business only in Wisconsin, no apportionment applies and all of the unitary business's income is taxable by Wisconsin unless specifically exempt. The following rules apply to the apportionment of income of a unitary business:
Tax 2.62(2)(d)1.
1. For any participant in the unitary business that is not a member of a commonly controlled group of corporations as provided in s.
Tax 2.61 (3), the participant's income from the unitary business is generally apportioned in the manner provided by ss.
Tax 2.39,
2.45,
2.46,
2.465,
2.47,
2.475,
2.48,
2.49,
2.495,
2.50, or
2.502, as applicable. However, the participant may be required to apportion its income under the combined reporting rules provided in s.
Tax 2.61 if certain conditions apply, as further explained in s.
Tax 2.61 (2) (f).
Tax 2.62(2)(d)2.
2. For any participant in the unitary business that is a member of a commonly controlled group of corporations as provided in s.
Tax 2.61 (3), the participant's income from the unitary business shall be apportioned under the combined reporting rules provided in s.
Tax 2.61.
Tax 2.62(2)(d)3.
3. A corporation that is engaged in the unitary business may have both apportionable income and nonapportionable income, as provided in s.
71.25 (5), Stats.
Tax 2.62(2)(e)
(e) Members of unitary business that are not in combined group. It is possible that one or more members of a unitary business may not be members of a combined group. Members of a unitary business that may not be members of a combined group include the following:
Tax 2.62(2)(e)1.
1. Individuals or entities that are considered “pass-through entities" for purposes of combined reporting under s.
71.255 (1) (m), Stats. This includes partnerships, limited liability companies treated as partnerships, tax-option corporations, estates, trusts, real estate investment trusts, regulated investment companies, real estate mortgage investment conduits, and financial asset securitization investment trusts.
Tax 2.62(2)(e)2.
2. Corporations whose net income and apportionment factors are not subject to combination under the water's edge rules of s.
Tax 2.61 (4).
Tax 2.62(2)(e)3.
3. Corporations that are related under the rules of sections
267 or
1563 of the Internal Revenue Code but are not in a “commonly controlled group" as provided under s.
Tax 2.61 (3).
Tax 2.62(2)(f)
(f) Members of combined group that are not in unitary business. A combined group may include corporations that are not engaged in a unitary business if the combined group's designated agent has properly made the controlled group election as provided in s.
Tax 2.63.
Tax 2.62(3)(a)(a)
General. Participants in a commonly controlled economic enterprise have sharing or exchange of value among them and a significant flow of value to the separate parts, and thus are a unitary business, if any of the following are true:
Tax 2.62(3)(a)1.
1. The participants in the enterprise contribute or are expected to contribute in a nontrivial way to each other's profitability.
Tax 2.62(3)(a)2.
2. Each participant in the enterprise is either dependent on, or is depended upon by, one or more other participants in the enterprise for achieving one or more nontrivial business objectives.
Tax 2.62(3)(a)3.
3. The economic enterprise offers one or more participants some economies of scale or economies of scope that benefit the enterprise.
Tax 2.62(3)(a)4.
4. The prices charged on transactions between participants in the enterprise are inconsistent with the arms-length principle. However, if these prices are consistent with the arms-length principle, that fact does not negate in any way the existence of a unitary business (
Exxon Corp. Tax 2.62(3)(b)
(b) Examples of flow of value. Activities between participants that constitute a flow of value between them include any of the following:
Tax 2.62(3)(b)4.
4. Interplay in the area of corporate expansion, including but not limited to common future planning or development of the enterprise.
Tax 2.62(3)(b)5.
5. Providing technical assistance, general operational guidance, or overall operational strategic advice.
Tax 2.62(3)(b)7.
7. Sharing use of trade names, patents, or other intellectual property.
Tax 2.62(4)
(4) Unity of operation and use. This subsection explains when participants in a commonly controlled economic enterprise are considered a unitary business because they have unity of operation and use.
Tax 2.62(4)(a)
(a) General. If the participants in a commonly controlled economic enterprise have both unity of operation and unity of use, they shall be considered engaged in a unitary business.
Tax 2.62(4)(b)
(b) Unity of operation. Unity of operation means there is functional integration among the participants, and is evidenced generally by shared support functions. Activities that indicate unity of operation include:
Tax 2.62(4)(b)1.
1. Centralized purchasing, marketing, advertising, accounting, or research and development.
Tax 2.62(4)(b)2.
2. Intercorporate sales or leases, including equipment and real estate.
Tax 2.62(4)(b)3.
3. Intercorporate services, including administrative, data management, computer support, employee benefits, human resources, insurance, tax compliance, legal, financial, and cash management services.
Tax 2.62(4)(b)5.
5. Intercorporate use of proprietary materials, including trade names, trademarks, service marks, patents, copyrights, and trade secrets.
Tax 2.62(4)(c)
(c) Unity of use. Unity of use is evidenced generally by centralized management or use of centralized policies. Factors that indicate unity of use include:
Tax 2.62(5)
(5) Factors considered by u.s. supreme court. Since, as provided in s.
71.255 (1) (n), Stats., the definition of “unitary business" shall be construed to the broadest extent permitted by the U.S. Constitution, case law provides further guidance to determine whether a unitary business exists. Subsections
(3) and
(4) are reflective of that case law. Factors that have been considered by the U.S. Supreme Court to be determinative of a unitary business include:
Tax 2.62(5)(b)
(b) A concrete relationship between the out-of-state and the in-state activities that is established by the existence of the unitary business (
Container Corp. of America v. Franchise Tax Bd. of California,
463 U.S. 159, 167,
103 S. Ct. 2983, 2941 (1983)).
Tax 2.62(5)(e)
(e) Some sharing or exchange of value not capable of precise identification or measurement — beyond the mere flow of funds arising out of a passive investment or a distinct business operation (
Container, 463 U.S. at 166, 103 S. Ct. at 2940).
Tax 2.62(6)
(6) Presumptions. The presumptions in pars.
(a) to
(g) apply when determining whether participants in a commonly controlled economic enterprise are considered a unitary business. Any of these presumptions may be rebutted by the taxpayer or by the department. However, the noncontrolling factors in par.
(h) may not be used to rebut these presumptions.
Tax 2.62(6)(a)
(a) Horizontal integration. An entity or commonly controlled group of entities is presumed to be engaged in a unitary business when all of its activities are in the same general line of business.
Tax 2.62(6)(b)
(b) Vertical integration. An entity or commonly controlled group of entities is presumed to be engaged in a unitary business when its various divisions, segments, branches, or affiliates are engaged in different steps in a vertically structured enterprise.
Tax 2.62(6)(c)
(c) Centralized management. An entity or commonly controlled group of entities that might otherwise be considered as engaged in more than one unitary business is presumed to be engaged in one unitary business when there is strong central management coupled with the existence of centralized departments or affiliates for such functions as financing, advertising, research and development, or purchasing.
