SB376,14,3 (3) Computation election. (a) A top-tier corporation that is a member of a commonly controlled group may elect on the commonly controlled group's behalf, and in the manner prescribed by the department, to compute the income of each corporation that is a member of the commonly controlled group under sub.

(2) (b) for periods of 7 taxable years and until any top-tier corporation that is a member of the commonly controlled group notifies the department, in a manner prescribed by the department, before the last day of the last taxable year in any period of 7 taxable years that the top-tier corporation is terminating the election under this subsection. A termination under this paragraph takes effect on the first day of the first taxable year beginning after the top-tier corporation notifies the department under this paragraph.

SB376,15,2 (d) The department may grant a request by a top-tier corporation to terminate an election under this subsection before the first period of 7 taxable years under par. (c) expires, if the top-tier corporation shows good cause for granting the request, as determined by the department and consistent with section 1502 of the Internal Revenue Code.

(f), if an election by a top-tier corporation on behalf of the members of a commonly controlled group under this subsection is terminated, no top-tier corporation may make an election on behalf of the members of the same commonly controlled group until 7 taxable years have elapsed from the day that the termination of the original election took effect.

SB376,15,12 (f) The department may grant a request by a top-tier corporation to make an election under this subsection before the period of 7 taxable years under par. (e) have elapsed, if the top-tier corporation shows good cause for granting the request, as determined by the department and consistent with section 1502 of the Internal Revenue Code.

SB376,15,24 (4) Accounting period. For purposes of this section, the income under ss. 71.26 and 71.45, the apportionment factors under ss. 71.25 and 71.45, and the tax credits under ss. 71.28 and 71.47 of all corporations that are members of a combined reporting group shall be determined by using the same accounting period. If the combined reporting group has a common parent corporation, the accounting period of the common parent corporation shall be used to determine the income, the apportionment factors, and the tax credits of all the corporations that are members of the combined reporting group. If the combined reporting group has no common parent corporation, the income, the apportionment factors, and the tax credits of the combined reporting group shall be determined using the accounting period of the member of the combined reporting group that has the most significant operations on a recurring basis in this state, as determined by the department.

SB376,16,9 (5) Filing returns. (a) Corporations with the same accounting period. Corporations that must file a combined report under this section and that have the same accounting period may file a group return, as prescribed by the department, that reports the aggregate state franchise or state income tax liability of all of the members of the combined reporting group. Corporations that are required to file a combined report under this section may file separate returns reporting the respective apportionment of the corporation's state franchise or state income tax liability as determined under sub. (2), if each corporation filing a separate return pays its own apportionment of its state franchise or state income tax liability.

SB376,16,23 (b) Corporations with different accounting periods. Corporations that are required to file a combined report and that have different accounting periods shall file separate returns and shall use the actual figures from the financial records of the corporations to determine the proper income and income-related computations to convert to a common accounting period. Corporations that are required to file a combined report may use a proportional method to convert income to a common accounting period if the results of the proportional method do not materially misrepresent the income apportioned to this state. The apportionment factors under ss. 71.25 and 71.45 and the tax credits under ss. 71.28 and 71.47 shall be computed according to the same method used to determine the income under ss. 71.26 and 71.45 for the common accounting period. If a corporation performs an interim closing of its financial records to determine the income attributable to the common accounting period, the actual figures from the interim closing shall be used to convert the apportionment factors and tax credits to the common accounting period.

SB376,17,15 (c) Designated agent. 1. For corporations that are subject to this section and that file a group return under par. (a), the parent corporation of the combined reporting group is the sole designated agent for each member of the combined reporting group including the parent corporation, if the parent corporation is a taxpayer member of the combined reporting group and income of the parent corporation is included on the group return. If the parent corporation is not a taxpayer member or if the parent corporation's income is not included on the group return, the taxpayer members may appoint a taxpayer member to be the designated agent. If the parent corporation of the combined reporting group is not eligible to be the designated agent and no taxpayer member is appointed to be the designated agent, the designated agent is the taxpayer member that has the most significant operations in this state on a recurring basis, as determined by the department. The designated agent, as determined under this subdivision, remains the designated agent until the designated agent is no longer a taxpayer member or until the taxpayer members appoint a different designated agent. If the designated agent changes, the combined reporting group shall notify the department of such a change, in a manner prescribed by the department.

SB376,18,13 2. The designated agent shall file the group return under par. (a), shall file for any extensions under s. 71.24 (7) or 71.44 (3), shall file amended reports and claims for refund or credit, and shall send and receive all correspondence with the department regarding a group return. Any notice the department sends to the designated agent is considered a notice sent to all members of the combined reporting group. Any refund with respect to a group return shall be paid to and in the name of the designated agent and shall discharge any liability of the state to any member of a combined reporting group regarding the refund. The combined reporting group filing a group return under par. (a) shall pay all taxes, including estimated taxes, in the designated agent's name. The designated agent shall participate on behalf of the members of the combined reporting group in any investigation or hearing requested by the department regarding a group return and shall produce all information requested by the department regarding a group return. The designated agent may execute a power of attorney on behalf of the members of the combined reporting group. The designated agent shall execute waivers, closing agreements, and other documents regarding a group return filed under par. (a) and any waiver, agreement, or document executed by the designated agent shall be considered as executed by all members of the combined reporting group. If the department acts in good faith with a combined reporting group member that represents itself as the designated agent for the combined reporting group but that combined reporting group member is not the designated agent, any action taken by the department with that combined reporting group member has the same effect as if that combined reporting group member were the actual designated agent for the combined reporting group.

SB376,18,17 (d) Part-year members. If a corporation becomes a member of a combined reporting group or ceases to be a member of a combined reporting group after the beginning of a common accounting period, the corporation's income shall be apportioned to this state as follows:

SB376,19,2 1. If the corporation is required to file 2 or more short-period federal returns for the common accounting period, the income for the short period in which the corporation was a member of a combined reporting group shall be determined as provided under sub. (2), the corporation shall join in filing a combined report for that short period, and the corporation may join in filing a group return for that short period. The income for the remaining short period shall be reported on a separate return under s. 71.26 or 71.45. If the corporation becomes a member of another combined reporting group in the remaining short period, the corporation's income shall be determined for the remaining short period as provided under sub. (2).

SB376,19,4 2. If the corporation is not required to file federal short-period returns, the corporation shall file a separate return. Income shall be determined as follows:

SB376,19,6 a. As provided under sub. (2) for any period that the corporation was a member of a combined reporting group.

SB376,19,8 b. As a separate entity under s. 71.26 or 71.45 for any period that the corporation was not a member of a combined reporting group.

SB376,19,12 (e) Amended group return. The election to file a group return under this section applies to an amended group return that includes the same corporations that joined in the filing of the original group return. Under this section, an amended group return shall be filed as follows:

SB376,19,21 1. If an election to file a group return that is in effect for a taxable year is revoked for the taxable year because the combined reporting group that filed the group return is not subject to sub. (2), as determined by the department, the designated agent for the combined reporting group may not file an amended group return. The designated agent and each corporation that joined in filing the group return shall file a separate amended return. To compute the tax due on a separate amended return, a corporation that files a separate amended return shall consider all of the payments, credits, or other amounts, including refunds, that the designated agent allocated to the corporation.

SB376,20,2 2. If a change in tax liability under this section is the result of the removal of a corporation from a combined reporting group because the corporation was not eligible to be a member of the combined reporting group for the taxable year, as determined by the department, the designated agent shall file an amended group return and the ineligible corporation shall file a separate amended return.

SB376,20,8 3. If a corporation erroneously fails to join in the filing of a group return, the designated agent shall file an amended group return that includes the corporation. If a corporation that erroneously fails to join in the filing of a group return has filed a separate return, the corporation shall file an amended separate return that shows no net income, overpayment, or underpayment, and shows that the corporation has joined in the filing of a group return.

SB376,20,10 (6) Income computation under combined reporting. For the purposes of sub. (2), income attributable to this state shall be determined as follows:

SB376,20,25 (a) Determine the net income of each member of a combined reporting group under s. 71.26 or 71.45, as appropriate, before deducting net business losses. A member of a combined reporting group may determine its net loss or net income under a method of accounting or an election authorized under s. 71.26 (3) (y), 71.30 (1), 71.45 (2) (a) 13., or 71.49 (2), as appropriate, regardless of the accounting method used to determine the net loss or net income of other members of the combined reporting group. After a member establishes an accounting method, or makes any election under this section, the member's net loss or net income shall be consistently determined in the combined report of all members of the combined reporting group and in the group return filed by the taxpayer members or in the separate return filed by the members. If a corporation is engaged in 2 or more trades or businesses that are required to use different apportionment formulas under s. 71.25 or 71.45, the net income for each trade or business shall be computed separately. A unitary business with operations in a foreign country shall compute its net loss or net income as provided by rule by the department.

SB376,21,2 (b) Adjust each member's income, as determined under par. (a), as provided under s. 71.30.

SB376,21,8 (c) From the amount determined under par. (b), subtract intercompany transactions, as provided by rule by the department, such that intercompany accounts of assets, liabilities, equities, income, costs, or expenses are excluded from the income determination to accurately reflect the income, the apportionment factors, and the tax credits in a combined report that is filed under this section. An intercompany transaction includes the following:

SB376,21,11 1. Income or gain from sales, exchanges, contributions, or other transfers of tangible or intangible property from a member of the combined reporting group to another member of the combined reporting group.
