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 corporations' financial records 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.

(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.

(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 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.

AB100-SA49,17,19 (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:

AB100-SA49,18,3 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.

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.
