Chapter 70

70.05(1) (1) The assessment of general property for taxation in all the towns, cities and villages of this state shall be made according to this chapter unless otherwise specifically provided. There shall be elected at the spring election one assessor for each taxation district not subject to assessment by a county assessor under s. 70.99 if election of the assessor is provided. Commencing with the 1977 elections and appointments made on and after January 1, 1977, no person may assume the office of town, village, city or county assessor unless certified by the department of revenue under s. 73.09 as qualified to perform the functions of the office of assessor. If a person who has not been so certified is elected to the office, the office shall be vacant and the appointing authority shall fill the vacancy from a list of persons so certified by the department of revenue.

70.05(2) (2) The governing body of any town, city or village not subject to assessment by a county assessor under s. 70.99 may provide for the selection of one or more assistant assessors to assist the assessor in the discharge of the assessor’s duties.

70.05(3) (3) The assessment of property of manufacturing establishments subject to assessment under s. 70.995 shall be made according to that section.

70.05(4) (4) All assessment personnel, including personnel of a county assessor system under s. 70.99, appointed under this section on or after January 1, 1977, shall have passed an examination and have been certified by the department of revenue as qualified for performing the functions of the office.

70.05(4m) (4m) A taxation district assessor may not enter upon a person’s real property for purposes of conducting an assessment under this chapter more than once in each year, except that an assessor may enter upon a person’s real property for purposes of conducting an assessment under this chapter more often if the property owner consents. A property owner may deny entry to an assessor of the interior of the owner’s residence if the owner has given prior notice to the assessor that the assessor may not enter the interior of the residence without the property owner’s permission. Each taxation district assessor shall create and maintain a database identifying all such property owners in the taxation district. A property owner’s refusal to allow the assessor to enter the interior of the owner’s residence shall not preclude the property owner from appearing before the board of review to object to the property’s valuation, as provided under s. 70.47 (7), and the assessor may not increase the property’s valuation based solely on the property owner’s refusal to allow entry.

70.05(4n) (4n) If a taxation district assessor is requesting to view the interior of a residence, the assessor shall provide written notice to the property owner of the property owner’s rights regarding the inspection of the interior of the owner’s residence. The notice shall be in substantially the following form:

PROPERTY OWNER RIGHTS

You have the right to refuse entry into your residence pursuant to section 70.05 (4m) of the Wisconsin statutes. Entry to view your property is prohibited unless voluntarily authorized by you. Pursuant to section 70.05 (4m) of the Wisconsin statutes, you have the right to refuse a visual inspection of the interior of your residence and your refusal to allow an interior inspection of your residence will not be used as the sole reason for increasing your property tax assessment. Refusing entry to your residence also does not prohibit you from objecting to your assessment pursuant to section 70.47 (7) of the Wisconsin statutes. Please indicate your consent or refusal to allow an interior visual inspection of your residence.

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.

70.11(2) (2) Municipal property and property of certain districts, exception.

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. Leasing the property exempt under this subsection, regardless of the lessee and the use of the leasehold income, does not render that property taxable.
