3. If a corporation erroneously fails to join in the filing of a combined report, the designated agent shall file an amended combined report that includes the corporation. If a corporation that erroneously fails to join in the filing of a combined report 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 combined report.
(5) INCOME COMPUTATION UNDER COMBINED REPORTING. Under the combined reporting method, income attributable to this state shall be determined as follows:
(a) Determine the net income of each corporation under s. 71.26, 71.34 (1) or 71.45, including a general or limited partner's share of income to the extent that the general or limited partner and the partnership in which the general or limited partner invests are engaged in a unitary business, regardless of the percentage of the general or limited partner's ownership in the partnership.
(b) Adjust each corporation's income, as determined under par. (a), as provided under s. 71.30.
(c) From the amount determined under par. (b), subtract intercompany transactions such that intercompany accounts of assets, liabilities, equities, income, costs or expenses are excluded from the determination of income to accurately reflect the income, the apportionment factors and the tax credits in a combined report that is filed under this section. Distributions of intercompany dividends that are paid from nonbusiness earnings or nonbusiness profits, or distributions of intercompany dividends that are paid from earnings or profits that are accumulated before the payer corporation becomes a member of an affiliated group that is engaged in a unitary business, may not be excluded from the income of the recipient corporation. An intercompany distribution that exceeds the payer corporation's earnings or profits or stock basis shall not be considered income from an intercompany sale of an asset and shall not be excluded as income from an intercompany transaction. Intercompany dividends that are paid from earnings or profits from a unitary business income shall be considered as paid first from current earnings or profits and then from accumulations from prior years in reverse order of accumulation. An intercompany transaction includes the following:
1. Income from sales of inventory from one member of the affiliated group to another member of the affiliated group.
2. Gain or loss from sales of intangible assets from one member of the affiliated group to another member of the affiliated group.
3. Gain or loss on sales of fixed assets or capitalized intercompany charges from one member of the affiliated group to another member of the affiliated group.
4. Loans, advances, receivables and similar items that one member of the affiliated group owes to another member of the affiliated group, including interest income and interest expense related to these items.
5. Stock or other equity of one member of the affiliated group that is owned or controlled by another member of the affiliated group.
6. Except as provided in par. (c) (intro.), intercompany dividends paid out of earnings or profits from a unitary business income.
7. Annual rent paid by one member of the affiliated group to another member of the affiliated group.
8. Management or service fees paid by one member of the affiliated group to another member of the affiliated group.
9. Income or expenses allocated or charged by one member of the affiliated group to another member of the affiliated group.
(d) From the amount determined under par. (c) for each corporation, subtract nonbusiness income, net of related expenses, and add nonbusiness losses, net of related expenses, to determine each corporation's apportionable net income or apportionable net loss.
(e) Calculate the apportionment factors under sub. (6) and multiply each corporation's apportionable net income or apportionable net loss, as determined under par. (d), by the corporation's apportionment fraction as determined under s. 71.25 (6).
(f) To the amount determined under par. (e), add each corporation's nonbusiness income attributable to this state and subtract each corporation's nonbusiness losses attributable to this state.
(g) To the amount determined under par. (f), subtract each corporation's net business loss carry-forward under s. 71.26 (4) or 71.45 (4). A corporation may not carry forward a business loss from taxable years ending before January 1, 2000, if the corporation was not subject to this state's income or franchise tax for taxable years ending before January 1, 2000.
(6) APPORTIONMENT FACTOR COMPUTATION UNDER COMBINED REPORTING. Under the combined reporting method, this state's apportionment factors are determined as follows:
(a) Determine the numerator and the denominator of each corporation's apportionment factors as determined under s. 71.25 or 71.45, including a general or limited partner's share of the numerator and the denominator of the apportionment factors to the extent that the general or limited partner and the partnership in which the general or limited partner invests are engaged in a unitary business, regardless of the percentage of the general or limited partner's ownership in the partnership.
(b) Subtract intercompany transactions under sub. (5) (c) from both the numerators and the denominators as determined under par. (b).
(c) Add the denominators of the apportionment factors for each corporation, as determined under par. (b), to arrive at the combined denominators.
(d) Compute each corporation's apportionment factors by dividing the corporation's numerator as determined under par. (b) by the combined denominator as determined under par. (c).
(7) NET OPERATING LOSSES. For the first 2 taxable years that a combined report is filed under this section, the net operating loss for each member of an affiliated group that files a combined report is determined by adding each member's share of nonbusiness income to each member's share of business income and subtracting each member's share of nonbusiness loss from each member's share of business loss. Beginning with the 3rd taxable year that a combined report is filed under this section, if a member of an affiliated group that files a combined report has a positive net income as determined under sub. (5), the affiliated group shall only deduct the amount of the net operating loss carry-forward attributable to that member.
(8) ESTIMATED TAX PAYMENTS. (a) For the first 2 taxable years that a combined report is filed under this section, estimated taxes may be paid on a group basis or on a separate basis. The amount of any separate estimated taxes paid in the first 2 taxable years that a combined report is filed shall be credited against the group's tax liability. The designated agent shall notify the department of any estimated taxes paid on a separate basis in the first 2 taxable years that a combined report is filed.
(b) If a combined report is filed for 2 consecutive taxable years, estimated taxes shall be paid on a group basis for each subsequent taxable year until such time as separate returns are filed by the corporations that were members of an affiliated group that filed combined reports under this section. For each taxable year in which combined estimated payments are required under this subsection, the department shall consider the affiliated group filing a combined report to be one taxpayer. If a corporation subject to this section files a separate return in a taxable year following a year in which the corporation joined in filing a combined report, the amount of any estimated tax payments made on a group basis for the previous year shall be credited against the tax liability of the corporation that files a separate return, as allocated by the designated agent with the department's approval.
(c) If an affiliated group pays estimated taxes on a group basis for a taxable year or for any part of a taxable year, and the members of the affiliated group file separate returns for the taxable year, the designated agent, with the department's approval, shall allocate the estimated tax payments among the members of the affiliated group.
(d) If estimated taxes are paid on a group basis for a taxable year but the group does not file a combined report for the taxable year and did not file a combined report for the previous taxable year, the estimated tax shall be credited to the corporation that made the estimated tax payment on the group's behalf.
(9) INTEREST FOR UNDERPAYMENT OF ESTIMATED TAX. (a) General. The amount of interest that is due for an underpayment of estimated taxes under sub. (8) shall be computed as follows:
1. For the first year in which a combined report is filed, the amount of interest that is due for an underpayment of estimated taxes shall be determined by using the aggregate of the tax and income shown on the returns filled by the members of the group for the previous year.
2. For estimated taxes paid under sub. (8) (c), the amount of interest that is due from a group member for an underpayment of estimated taxes paid by the group member shall be determined by using the group member's separate items from the combined report filed for the previous year and the group member's allocated share of the combined estimated payments for the current year. The designated agent shall report the group member's allocated share of the combined estimated payments for the current year to the department, in the manner prescribed by the department.
(b) Entering a group. For a corporation that becomes a member of an affiliated group during a common accounting period under sub. (3), the amount of interest that is due for an underpayment of estimated taxes shall be allocated to the corporation as follows:
1. If a corporation becomes a member of an affiliated group at the beginning of a common accounting period, the corporation shall include with the corresponding items on the combined report for the previous common accounting period the separate items shown on the corporation's return for the previous taxable year.
2. If a corporation is not a member of an affiliated group for an entire common accounting period, the corporation shall include with the corresponding items on the combined report for the current taxable year the corporation's separate items for that portion of the common accounting period that the corporation was a member of the affiliated group.
3. To determine the separate items under subds. 1. and 2., if a corporation is a member of an affiliated group during a portion of a common accounting period in which the corporation becomes a member of another affiliated group, the corporation's separate items shall include the separate items that are attributed to the corporation by the designated agent of the first affiliated group.
(c) Leaving a group. For a corporation that leaves an affiliated group during a common accounting period under sub. (3), the amount of interest that is due for an underpayment of estimated taxes shall be allocated as follows:
1. The separate items attributed by the designated agent to the corporation for the common accounting period during which the corporation leaves the affiliated group shall be excluded from the corresponding items of the affiliated group for the current common accounting period and all the common accounting periods following the corporation's departure from the affiliated group.
2. A corporation that leaves an affiliated group shall consider the separate items attributed to the corporation by the designated agent of the affiliated group to determine the amount of interest that is due from the corporation for an underpayment of estimated taxes under sub. (8).
(10) ASSESSMENT NOTICE. If the department sends a notice of taxes that are owed by an affiliated group to the designated agent, the notice shall name each corporation that is a member of the affiliated group during any part of the period covered by the notice. The department's failure to name a member of the affiliated group on a notice under this subsection shall not invalidate the notice as to the unnamed member of the affiliated group. Any levy, lien or other proceeding to collect the amount of a tax assessment under this section shall name the corporation from which the department shall collect the assessment. If a corporation that joined in the filing of a combined report leaves the affiliated group, the department shall send the corporation a copy of any notice sent to the affiliated group under this subsection if the corporation notifies the department that the corporation is no longer a member of the affiliated group and if the corporation requests in writing that the department send notices under this subsection to the corporation. The department's failure to comply with a corporation's request to receive a notice does not affect the tax liability of the corporation.
(11) LIABILITY FOR TAX, INTEREST AND PENALTY. If members of an affiliated group file a combined report, the members of the affiliated group shall be jointly and severally liable for any combined tax, interest or penalty. The liability of a member of an affiliated group for any combined tax, interest or penalty shall not be reduced by an agreement with another member of the affiliated group or by an agreement with another person.
(12) PRESUMPTIONS AND BURDEN OF PROOF. An affiliated group shall be presumed to be engaged in a unitary business and all of the income of the unitary business shall be presumed to be apportionable business income under this section. A corporation, partnership, limited liability company or tax-option corporation has the burden of proving that it is not a member of an affiliated group that is subject to this section. The department shall promulgate rules to implement this section.
