Chapter 71

71.775(4)(dm) (dm) Section 71.29 (3), (3m), (4), (5), (6), and (11), as it applies to estimated payments of income and franchise taxes for corporations, also applies to estimated payments of the withholding tax imposed under sub. (2) for pass-through entities.

71.775(4)(em) (em) Except as provided in par. (fm), in the case of any underpayment of estimated withholding taxes under par. (cm), interest shall be added to the aggregate withholding tax for the taxable year at the rate of 12 percent per year on the amount of the underpayment for the period of the underpayment. In this paragraph, “period of the underpayment” means the time period beginning with the due date of the installment and ending on either the unextended due date of the return under par. (a) or the date of payment, whichever is earlier. If 90 percent of the tax due under sub. (2) for the taxable year is not paid by the unextended due date of the return under par. (a), the difference between that amount and the estimated taxes paid, along with any interest due, shall accrue delinquent interest in the same manner as income and franchise taxes under s. 71.82 (2) (a).

71.775(4)(fm) (fm) No interest is required under par. (em) for a pass-through entity if any of the following conditions apply:

71.775(4)(fm)1. 1. The amount of withholding tax due under sub. (2) is less than $500.

71.775(4)(fm)2. 2. The amount of withholding tax due under sub. (2) is less than $5,000, the pass-through entity had no withholding tax liability under sub. (2) for the preceding taxable year, and the preceding taxable year was 12 months.

71.775(4)(fm)3. 3. The secretary of revenue determines that because of casualty, disaster, or other unusual circumstances it is not equitable to impose interest.

71.775(4)(g) (g) Except as provided under par. (h), the amount of each installment required under par. (cm) is 25 percent of the lesser of the following amounts:

71.775(4)(g)1. 1. Ninety percent of the withholding tax under sub. (2) that is due for the taxable year.

71.775(4)(g)2. 2. The withholding tax due under sub. (2) for the preceding taxable year, except that this subdivision does not apply if the preceding taxable year was less than 12 months or if the pass-through entity did not file a return under par. (a) for the preceding taxable year.

71.775(4)(h) (h) If 22.5 percent for the first installment, 45 percent for the 2nd installment, 67.5 percent for the 3rd installment, and 90 percent for the 4th installment of the tax due under sub. (2) for the taxable year; computed by annualizing, under methods prescribed by the department, the pass-through entity’s income for the months in the taxable year ending before the installment’s due date; is less than the installment required under par. (g), the pass-through entity may pay the amount under this paragraph, rather than the amount under par. (g). For purposes of computing annualized income under this paragraph, the apportionment percentage computed under s. 71.25 (6), (10), and (12) from the return under par. (a) filed for the previous taxable year may be used if that return was filed with the department on or before the due date of the installment for which the income is being annualized and if the apportionment percentage on that previous year’s return was greater than zero. Any pass-through entity that pays an amount calculated under this paragraph shall increase the next installment computed under par. (g) by an amount equal to the difference between the amount paid under this paragraph and the amount that would have been paid under par. (g).

71.775(4)(i) (i) On or before the due date, including extensions, of the entity’s return, a pass-through entity that withholds tax under sub. (2) shall annually notify each of its nonresident partners, members, shareholders, or beneficiaries of the amount of the tax withheld under sub. (2) that the pass-through entity paid on the nonresident partner’s, member’s, shareholder’s, or beneficiary’s behalf. The pass-through entity shall provide a copy of the notice to the department with the return that it files for the taxable year.

71.775(4)(j) (j) A nonresident partner, member, shareholder, or beneficiary of a pass-through entity may claim a credit, as prescribed by the department, on his or her Wisconsin income or franchise tax return for the amount withheld under sub. (2) on his or her behalf for the tax period for which the income of the pass-through entity is reported.

71.775(4)(k) (k) Any tax withheld under this section shall be held in trust for this state, and a pass-through entity subject to withholding under this section shall be liable to the department for the payment of the tax withheld. No partner, member, shareholder, or beneficiary of a pass-through entity shall have any right of action against the pass-through entity with respect to any amount withheld and paid in compliance with this section.

71.775(4)(L) (L) The department shall deem timely paid the estimated payments of the withholding tax imposed under sub. (2) that become due during the period beginning on January 1, 2009, and ending on July 1, 2009, provided that such estimated tax payments are paid by the next installment due date that follows in sequence following July 1, 2009. However, if the next installment due date following July 1, 2009, is less than 45 days after July 1, 2009, such estimated payments, in addition to the payment due less than 45 days after July 1, 2009, shall be deemed timely paid if paid by the next subsequent installment due date.
