70.34 Annotation “True cash value” is not a figure that can be determined by bargaining with the taxpayer, and such an agreement would be void. The unsupported statement of the taxpayer has no probative value. State ex rel. Berg Equipment Corp. v. Town of Spencer Board of Review, 53 Wis. 2d 233, 191 N.W.2d 892 (1971).

70.34 Annotation When there are no actual sales, cost, depreciation, replacement value, income, industrial conditions, location and occupancy, sales of like property, book value, insurance carried, value asserted in a prospectus, and appraisals are all relevant to determination of market value for assessment purposes. State ex rel. Mitchell Aero, Inc. v. Board of Review, 74 Wis. 2d 268, 246 N.W.2d 521 (1976).

70.34 Annotation A market data or sales approach was proper when 94 percent of machines were leased and only six percent were sold. An income capitalization approach has been used only when no sales exist. Xerox Corp. v. DOR, 114 Wis. 2d 522, 339 N.W.2d 357 (Ct. App. 1983).

No return required under this section is controlling on the assessor in any respect in the assessment of any property.

70.35(4) (4) For assessments made before January 1, 2024, any person, firm or corporation who refuses to so testify or who fails, neglects or refuses to make and file the return of personal property required by this section shall be denied any right of abatement by the board of review on account of the assessment of such personal property unless such person, firm, or corporation shall make such return to such board of review together with a statement of the reasons for the failure to make and file the return in the manner and form required by this section.

70.365 70.365 Notice of changed assessment. When the assessor assesses any taxable real property, or any improvements taxed as personal property under s. 77.84 (1), and arrives at a different total than the assessment of it for the previous year, the assessor shall notify the person assessed if the address of the person is known to the assessor, otherwise the occupant of the property. However, the assessor is not required to provide notice under this section if land is classified as agricultural land, as defined in s. 70.32 (2) (c) 1g., for the current year and previous year and the difference between the assessments is $500 or less. If the assessor determines that land assessed under s. 70.32 (2r) for the previous year is no longer eligible to be assessed under s. 70.32 (2r), and the current classification under s. 70.32 (2) (a) is not undeveloped, agricultural forest, productive forest land, or other, the assessor shall notify the person assessed if the assessor knows the person’s address, or otherwise the occupant of the property, that the person assessed may be subject to a conversion charge under s. 74.485. Any notice issued under this section shall be in writing and shall be sent by ordinary mail at least 15 days before the meeting of the board of review or before the meeting of the board of assessors in 1st class cities and in 2nd class cities that have a board of assessors under s. 70.075, except that, in any year in which the taxation district conducts a revaluation under s. 70.05, the notice shall be sent at least 30 days before the meeting of the board of review or board of assessors. The notice shall contain the amount of the changed assessment and the time, date, and place of the meeting of the local board of review or of the board of assessors. The notice shall also include the following: “Under Wisconsin law, generally, the assessor may not change the assessment of property based solely on the recent arm’s length sale of the property without adjusting the assessed value of comparable properties in the same market area. For information on the assessment of properties that have recently sold, visit the Internet site of the Department of Revenue at ... (Internet site address).” However, if the assessment roll is not complete, the notice shall be sent by ordinary mail at least 15 days prior to the date to which the board of review or board of assessors has adjourned, except that, in any year in which the taxation district conducts a revaluation under s. 70.05, the notice shall be sent at least 30 days prior to the date to which the board of review or board of assessors has adjourned. The assessor shall attach to the assessment roll a statement that the notices required by this section have been mailed and failure to receive the notice shall not affect the validity of the changed assessment, the resulting changed tax, the procedures of the board of review or of the board of assessors or the enforcement of delinquent taxes by statutory means. After the person assessed or the occupant of the property receives notice under this section, if the assessor changes the assessment as a result of the examination of the rolls as provided in s. 70.45 and the person assessed waives, in writing and on a form prescribed or approved by the department of revenue, the person’s right to the notice of the changed assessment under this section, no additional notice is required under this section. The secretary of revenue shall prescribe the form of the notice required under this section. The form shall include information notifying the taxpayer of the procedures to be used to object to the assessment. The form shall also indicate whether the person assessed may be subject to a conversion charge under s. 74.485.

70.365 Annotation Under s. 74.37 (4), a taxpayer must challenge an assessment in front of the board of review before filing an excessive assessment claim, unless the taxing authority fails to provide a notice of assessment under circumstances in which notice is required. Under this section, a notice of assessment is required only when the property’s assessed value has changed. After reading these statutes, it should have been clear to the taxpayer that: 1) because it did not receive a notice of assessment, its property’s assessed value for 2011 would be unchanged from 2010; and 2) if the taxpayer wanted to challenge the 2011 assessment, it needed to object before the board of review. These requirements did not violate the taxpayer’s rights to due process. Northbrook Wisconsin, LLC v. City of Niagara, 2014 WI App 22, 352 Wis. 2d 657, 843 N.W.2d 851, 13-1322.

70.37 70.37 Net proceeds occupation tax on persons extracting metalliferous minerals in this state.

70.37(1) (1) Legislative findings. The legislature finds that:

70.37(1)(a) (a) The existence has been announced of several economically significant ore bodies containing copper, zinc, lead, taconite and other metalliferous minerals in this state, including one of the largest zinc deposits in North America.

70.37(1)(b) (b) Metalliferous minerals are valuable, irreplaceable natural resources which, once removed, are forever lost as an economic asset to the state.

70.37(1)(c) (c) The activity of mining metalliferous minerals creates jobs, economic activity, tax revenues and other valuable benefits to the economy and residents of this state.

70.37(1)(d) (d) The activity of mining metalliferous minerals creates additional costs to the state and municipalities for highways, sewers, schools and other improvements which are necessary to accommodate the development of a metalliferous mining industry.

70.37(1)(e) (e) The activity of mining metalliferous minerals has a permanent and often damaging effect on the environment of the state.

70.37(1)(f) (f) The activity of mining metalliferous minerals significantly alters the quality of life in communities directly affected by mining.

70.37(1)(g) (g) As the size of a mining operation increases, the cost to the state and municipalities to support the operation increases, as does the damage to the environment. Furthermore, as the size of a mining operation increases, the person mining metalliferous minerals benefits from economies of scale in the mining operation.

70.37(1)(h) (h) A graduated net proceeds occupational tax, by taxing profitability at rates which vary with the level of profitability, encourages important state goals, such as:

70.37(1)(h)1. 1. Gradual, continuous and complete extraction of metalliferous minerals.

70.37(1)(h)2. 2. Continued stable employment.

70.37(1)(h)3. 3. Taxation according to ability to pay.

70.37(1)(h)4. 4. Taxation based on the privileges enjoyed by persons mining metalliferous metallic minerals.

70.37(1)(i) (i) Municipalities incur long-term economic costs as a result of metalliferous mineral mining after the mining operation shuts down. An impact fund, in which is deposited a portion of the tax revenues, should assure that moneys will be available to such municipalities for long- and short-term costs associated with social, educational, environmental and economic impacts of metalliferous mineral mining.

70.37(2) (2) Legislative intent. It is the declared intent of the legislature to establish a net proceeds occupation tax on persons engaged in the activity of mining metalliferous minerals in this state. The tax is established in order that the state may derive a benefit from the extraction of irreplaceable metalliferous minerals and in order to compensate the state and municipalities for costs, past, present and future, incurred or to be incurred as a result of the loss of valuable irreplaceable metallic mineral resources.
