70.421(3) (3) The tax provided for shall be separately assessed to the person chargeable therewith by the assessor and shall be included in the assessment roll annually submitted by such assessor to the town, village or city clerk and shall be entered by said clerk on the tax roll. Such tax shall be paid and collected in the taxing district where such refinery is situated, and shall be deductible from gross income for income or franchise tax purposes in the same manner as personal property taxes are deductible by corporations in computing net income under s. 71.26 (2). Such tax is a special tax under ch. 74 and the entire proceeds of such tax shall be retained by such taxing district.

70.421(4) (4) If the assessor or board of review has reason to believe that the list or statement made by any person is incorrect, or when any such person has failed or refused to furnish a list or statement as required by law, the assessor or board of review shall place on the assessment roll such taxes against such person as the assessor or board of review deems true and just, and in case such change or assessment is made by the assessor, the assessor shall give written notice of the amount of such assessment at least 6 days before the first or some adjourned meeting of the board of review; in case such change or assessment is made by the board of review, notice shall be given in time to allow such person to appear and be heard before the board of review in relation to said assessment; said notice may be served as a circuit court summons is served or by registered mail.

The result shall be the true assessed value of the property for the preceding year. The assessor shall make a marginal note of the correction on that year’s assessment roll.

70.43(3) (3) The dollar amount of the adjustment determined in the correction under sub. (2) shall be referred to the board of review and, if certified by that board, shall be entered in a separate section of the current assessment roll, as prescribed by the department of revenue, and shall be used to determine the amount of additional taxes to be collected or taxes to be refunded. The dollar amount of the adjustment may be appealed to the board of review in the same manner as other assessments. The taxes to be collected or refunded shall be determined on the basis of the net tax rate of the previous year, taking into account credits under s. 79.10. The taxes to be collected or refunded shall be reflected on the tax roll in the same manner as omitted property under s. 70.44, but any such adjustment may not be carried forward to future years. The governing body of the taxation district shall proceed under s. 74.41.

70.43(4) (4) As soon as practicable, the assessor shall provide written notice of the correction to the person assessed. That notice shall include information regarding that person’s appeal rights to the board of review.
