The city assessor may direct that all objections to valuations filed with the city assessor in writing, in the manner provided in s. 70.47 (13) [s. 70.47 (16)], shall be investigated by the board.

70.075 Note NOTE: The correct cross-reference is shown in brackets. Corrective legislation is pending.

70.075(4) (4) The concurrence of a majority of the board of assessors is necessary to determine any matter upon which the city assessor requires it to act. No notice need be given to the owners of the property assessed of any corrections or changes in assessments which are made prior to the day or days fixed in the notice specified under sub. (1) on which the assessments are to be open for examination, but any changes made thereafter and before the assessment roll is delivered to the board of review can only be made upon notice by 1st class mail to the person assessed if a resident of the city or, if a nonresident, an agent if there is one resident in the city or, if neither, the possessor of the property assessed if any, if the residence of the owner, agent or possessor is known to any member of the board of assessors.

70.075(5) (5) The city assessor may provide for committees of the board of assessors to make investigations including the investigations mentioned in sub. (3) and perform such other duties as may be prescribed. The city assessor shall chair the board of assessors, and may appoint as a member or chairperson of the various committees, himself or herself, an assistant assessor, or other officer or employee in the office of the city assessor.

70.075(6) (6) The board of assessors shall remain in session until all corrections and changes have been made, including all those resulting from investigations by committees of objections to valuations filed with the city assessor as provided in this section, after which the city assessor shall prepare the assessment rolls as corrected by the board of assessors and submit them to the board of review not later than the last Monday in July. A person assessed who has been notified of the determination of the board of assessors as required in sub. (4) is deemed to have accepted such determination unless the person notifies the city assessor in writing, within 15 days from the date that the notice of determination was issued under sub. (4), of a desire to present testimony before the board of review. After the board of review meets, the city assessor may appoint committees of the board of assessors to investigate any objections to the amount or valuation of any real or personal property which are referred to the city assessor by the board of review.

70.10 Annotation Nothing in this section requires a property to be classified based on its actual use or prevents an assessor from considering a property’s most likely use. West Capitol, Inc. v. Village of Sister Bay, 2014 WI App 52, 354 Wis. 2d 130, 848 N.W.2d 875, 13-1458.

70.109 70.109 Presumption of taxability. Exemptions under this chapter shall be strictly construed in every instance with a presumption that the property in question is taxable, and the burden of proof is on the person who claims the exemption.

70.109 Annotation Exemption from payment of taxes is an act of legislative grace; the party seeking the exemption bears the burden of proving entitlement. Exemptions are only allowed to the extent the plain language of a statute permits. For tax exemptions to be valid, they must be clear and express, and not extended by implication. In construing tax exemptions, courts apply a strict but reasonable construction resolving any doubts regarding the exemption in favor of taxability. United Rentals, Inc. v. City of Madison, 2007 WI App 131, 302 Wis. 2d 245, 733 N.W.2d 322, 05-1440.

70.11 70.11 Property exempted from taxation. The property described in this section is exempted from general property taxes if the property is exempt under sub. (1), (2), (18), (21), (27) or (30); if it was exempt for the previous year and its use, occupancy or ownership did not change in a way that makes it taxable; if the property was taxable for the previous year, the use, occupancy or ownership of the property changed in a way that makes it exempt and its owner, on or before March 1, files with the assessor of the taxation district where the property is located a form that the department of revenue prescribes or if the property did not exist in the previous year and its owner, on or before March 1, files with the assessor of the taxation district where the property is located a form that the department of revenue prescribes. Except as provided in subs. (3m) (c), (4) (b), (4a) (f), and (4d), leasing a part of the property described in this section does not render it taxable if the lessor uses all of the leasehold income for maintenance of the leased property or construction debt retirement of the leased property, or both, and, except for residential housing, if the lessee would be exempt from taxation under this chapter if it owned the property. Any lessor who claims that leased property is exempt from taxation under this chapter shall, upon request by the tax assessor, provide records relating to the lessor’s use of the income from the leased property. Property exempted from general property taxes is:

70.11(1) (1) Property of the state. Property owned by this state except land contracted to be sold by the state. This exemption shall not apply to land conveyed after September, 1933, to this state or for its benefit while the grantor or others for the grantor’s benefit are permitted to occupy the land or part thereof in consideration for the conveyance; nor shall it apply to land devised to the state or for its benefit while another person is permitted by the will to occupy the land or part thereof. This exemption shall not apply to any property acquired by the department of veterans affairs under s. 45.32 (5) and (7), 2017 stats., or to the property of insurers undergoing rehabilitation or liquidation under ch. 645. Property exempt under this subsection includes general property owned by the state and leased to a private, nonprofit corporation that operates a national ice training center, regardless of the use of the leasehold income.

Except as to land acquired under s. 59.84 (2) (d), this exemption shall not apply to land conveyed after August 17, 1961, to any such governmental unit or for its benefit while the grantor or others for his or her benefit are permitted to occupy the land or part thereof in consideration for the conveyance. The exemption under this subsection applies to the property of a regional planning commission that the commission owned prior to October 1, 2021. If a regional planning commission subsequently sells property exempt from taxation under this subsection, the exemption applies to property purchased and owned by the commission if the total size of all property owned by the commission is substantially similar in size to the total property owned by the commission prior to October 1, 2021. Any property of the regional planning commission in excess of that size restriction is subject to taxation under this chapter.
