70.73 (1) (c) At the time and place designated in the notice given under par. (b), the assessment roll shall be corrected by entering the correct names of the persons liable to assessment, both as to real and personal property, describing each parcel of land and giving the proper valuation to each parcel separately owned. The total valuation given to the separate tracts of real estate shall be equal to the valuation given to the same property when the several parcels were assessed together.

70.73 (1) (d) The valuation of parcels of land or correction of names of persons whose personal property is assessed under this subsection may be made at any time before the tax roll is returned to the county treasurer for the year in which the tax is levied. The valuation or correction of names, when made under this subsection, shall be held just and correct and be final and conclusive.

70.84 Inequalities may be corrected in subsequent year. If any such reassessment cannot be completed in time to take the place of the original assessment made in such district for said year, the clerk of the district shall levy and apportion the taxes for that year upon the basis of the original assessment roll, and when the reassessment is completed the inequalities in the taxes levied under the original assessment shall be remedied and compensated in the levy and apportionment of taxes in such district next following the completion of said reassessment in the following manner: Each tract of real estate, and, as to personal property, each taxpayer, whose tax shall be determined by such reassessment to have been relatively too high, shall be credited a sum equal to the amount of taxes charged on the original assessment in excess of the amount which would have been charged had such reassessment been made in time; and each tract of real estate, and, as to personal property, each taxpayer, whose tax shall be determined by such reassessment to have been relatively too low, shall be charged, in addition to all other taxes, a sum equal to the difference between the amount of taxes charged upon such unequal original assessment and the amount which would have been charged had such reassessment been made in time. The department of revenue, or its authorized agent, shall at any time have access to all assessment and tax rolls herein referred to for the purpose of assisting the local clerk and in order that the results of the reassessment may be carried into effect.

70.855 (1) Applicability. (intro.) The department of revenue shall assess real and personal property assessed as commercial property under s. 70.32 (2) (a) 2. if all of the following apply:

70.855 (1) (a) The property owner and the governing body of the municipality where the property is located submit a written request to the department on or before March 1 of the year of the assessment to have the department assess the property owner's real and personal commercial property located in the municipality.

70.855 (1) (b) The written request submitted under par. (a) specifies the items of personal property and parcels of real property for the department's assessment.

70.995 (1) (a) In this section “manufacturing property" includes all lands, buildings, structures and other real property used in manufacturing, assembling, processing, fabricating, making, or milling tangible personal property for profit. Manufacturing property also includes warehouses, storage facilities, and office structures when the predominant use of the warehouses, storage facilities, or offices is in support of the manufacturing property, and all personal property owned or used by any person engaged in this state in any of the activities mentioned, and used in the activity, including raw materials, supplies, machinery, equipment, work in process and finished inventory and when located at the site of the activity. Establishments engaged in assembling component parts of manufactured products are considered manufacturing establishments if the new product is neither a structure nor other fixed improvement. Materials processed by a manufacturing establishment include products of agriculture, forestry, fishing, mining, and quarrying. For the purposes of this section, establishments which engage in mining metalliferous minerals are considered manufacturing establishments.

70.995 (1) (b) Materials used by a manufacturing establishment may be purchased directly from producers, obtained through customary trade channels or secured without recourse to the market by transfer from one establishment to another under the same ownership. Manufacturing production is usually carried on for the wholesale market, for interplant transfer or to order for industrial users rather than for direct sale to a domestic consumer.

70.995 (4) Whenever real property or tangible personal property is used for one, or some combination, of the processes mentioned in sub. (3) and also for other purposes, the department of revenue, if satisfied that there is substantial use in one or some combination of such processes, may assess the property under this section. For all purposes of this section the department of revenue shall have sole discretion for the determination of what is substantial use and what description of real property or what unit of tangible personal property shall constitute “the property" to be included for assessment purposes, and, in connection herewith, the department may include in a real property unit, real property owned by different persons. Vacant property designed for use in manufacturing, assembling, processing, fabricating, making, or milling tangible property for profit may be assessed under this section or under s. 70.32 (1), and the period of vacancy may not be the sole ground for making that determination. In those specific instances where a portion of a description of real property includes manufacturing property rented or leased and operated by a separate person which does not satisfy the substantial use qualification for the entire property, the local assessor shall assess the entire real property description and all personal property not exempt under s. 70.11 (27). The applicable portions of the standard manufacturing property report form under sub. (12) as they relate to manufacturing machinery and equipment shall be submitted by such person.

70.995 (7) (b) Each 5 years, or more frequently if the department of revenue's workload permits and if in the department's judgment it is desirable, the department of revenue shall complete a field investigation or on-site appraisal at full value under ss. s. 70.32 (1) and 70.34 of all manufacturing property in this state.

70.995 (8) (b) 1. The department of revenue shall annually notify each manufacturer assessed under this section and the municipality in which the manufacturing property is located of the full value of all real and personal property owned by the manufacturer. The notice shall be in writing and shall be sent by 1st class mail or electronic mail. In addition, the notice shall specify that objections to valuation, amount, or taxability must be filed with the state board of assessors no later than 60 days after the date of the notice of assessment, that objections to a change from assessment under this section to assessment under s. 70.32 (1) must be filed no later than 60 days after the date of the notice, that the fee under par. (c) 1. or (d) must be paid and that the objection is not filed until the fee is paid. For purposes of this subdivision, an objection is considered timely filed if received by the state board of assessors no later than 60 days after the date of the notice or sent to the state board of assessors by certified mail in a properly addressed envelope, with postage paid, that is postmarked before midnight of the last day for filing. A statement shall be attached to the assessment roll indicating that the notices required by this section have been mailed and failure to receive the notice does not affect the validity of the assessments, the resulting tax on real or personal property, the procedures of the tax appeals commission or of the state board of assessors, or the enforcement of delinquent taxes by statutory means.

70.995 (12) (a) The department of revenue shall prescribe a standard manufacturing property report form that shall be submitted annually for each real estate parcel and each personal property account on or before March 1 by all manufacturers whose property is assessed under this section. The report form shall contain all information considered necessary by the department and shall include, without limitation, income and operating statements, fixed asset schedules, and a report of new construction or demolition. Failure to submit the report shall result in denial of any right of redetermination by the state board of assessors or the tax appeals commission. If any property is omitted or understated in the assessment roll in any of the next 5 previous years, the assessor shall enter the value of the omitted or understated property once for each previous year of the omission or understatement. The assessor shall affix a just valuation to each entry for a former year as it should have been assessed according to the assessor's best judgment. Taxes shall be apportioned and collected on the tax roll for each entry, on the basis of the net tax rate for the year of the omission, taking into account credits under s. 79.10. In the case of omitted property, interest shall be added at the rate of 0.0267 percent per day for the period of time between the date when the form is required to be submitted and the date when the assessor affixes the just valuation. In the case of underpayments determined after an objection under s. 70.995 (8) (d), interest shall be added at the average annual discount interest rate determined by the last auction of 6-month U.S. treasury bills before the objection per day for the period of time between the date when the tax was due and the date when it is paid.

71.17 (2) Lien on trust estate; income taxes levied against beneficiary. All income taxes levied against the income of beneficiaries shall be a lien on that portion of the trust estate or interest therein from which the income taxed is derived, and such taxes shall be paid by the fiduciary, if not paid by the distributee, before the same become delinquent. Every person who, as a fiduciary under the provisions of this subchapter, pays an income tax shall have all the rights and remedies of reimbursement for any taxes assessed against him or her or paid by him or her in such capacity, as provided in s. 70.19 (1) and (2), 2019 stats.
