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.

74.05 (1) Definition. In this section, “error in the tax roll" means an error in the description of any real or personal property, in the identification of the owner or person to whom the property is assessed or in the amount of the tax or an error resulting from a palpably erroneous entry in the assessment roll.

74.09 (2) Preparation. The clerk of the taxation district shall prepare the real and personal property tax bills. The form of the property tax bill shall be prescribed by the department of revenue and shall be uniform.

74.11 (6) (a) Payments made on or before January 31 and payments of taxes on improvements on leased land that are assessed as personal property shall be made to the taxation district treasurer.

74.11 (10) (a) 1. If all special assessments, special charges, and special taxes and personal property taxes due under sub. (3) or (4) are not paid in full and received by the proper official on or before 5 working days after the due date, the amounts unpaid are delinquent as of the day after the due date of the first installment or of the lump-sum payment.

74.11 (12) (a) (intro.) Except as provided in pars. par. (c) and (d), if a taxation district treasurer or county treasurer receives a payment from a taxpayer which is not sufficient to pay all amounts due, the treasurer shall apply the payment to the amounts due, including interest and penalties, in the following order:

74.11 (12) (b) The allocation under par. (a) 1g. 1m. to 4. is conclusive for purposes of settlement under ss. 74.23 to 74.29 and for determining delinquencies under this section.

74.12 (7) (a) If the first installment of real property taxes, personal property taxes on improvements on leased land or special assessments to which an installment option pertains is not received by the proper official on or before 5 working days after the due date of January 31, the entire amount of the remaining unpaid taxes or special assessments to which an installment option pertains on that parcel is delinquent as of February 1.
