(4) Redetermination.
(a) If after filing the reports specified in sub. (7) and after the department’s computation and assessment of license fees under sub. (2) it is determined that the amount of gross revenues reported is in error, the department shall compute the additional license fee to be paid or the amount of the overpayment of license fee to be refunded, as the case may be. If an additional license fee is due, the department shall give notice to the light, heat and power company against whom the license fee is to be levied. All such additional assessments and claims for refunds for excess license fees paid are subject to the same procedure for review and final determination as additional income or franchise tax assessments and claims for refunds under ch. 71 as far as the same may be applicable, except that appeals of denials of claims for refunds shall be made directly to the tax appeals commission and except that the additional license fees shall become delinquent 60 days after notice provided in this subsection or, if review proceedings are held, 60 days following final determination of the review proceedings. All additional license fees shall bear interest at the rate of 12 percent per year from the time they should have been paid to the date on which the additional fees shall become delinquent if unpaid.

All refunds of license fees under this subsection shall bear interest at the annual rate of 3 percent from the date of the original payment to the date when the refund is made. The time for making additional levies of license fees or claims for refunds of excess license fees paid, in respect to any year, shall be limited to 4 years after the time the report for such year was filed.
(5) Remedies. Delinquent license fees of any light, heat and power company, together with penalties and interest, for a lien upon all property of such company prior to all other liens, claims and demands, which lien may be enforced in an action in the name of the state in any court of competent jurisdiction against the property of such company within the state as an entirety. The remedies for nonpayment of taxes specified in s. 76.14 apply to nonpayment of license fees, penalties and interest referred to under this section.
(6) Administration.
(a) The records, books, accounts and papers of any light, heat and power company are subject to inspection and examination by the secretary of revenue or by the person that the secretary designates for that purpose.
(b) If any light, heat and power company that is required under this section to file a report fails to file a report within the time prescribed by law or as extended under sub. (7), and upon a showing by the department under s. 73.16 (4), there shall be added to the amount required to be shown as license fees on the report 5 percent of the amount of such fees if the failure is for not more than one month, with an additional 5 percent for each additional month or fraction thereof during which the failure continues, not exceeding 25 percent in the aggregate.
(c) If any light, heat and power company fails to make a report as required by sub. (7) within the time required, the department may enter an assessment against such company in a sum representing the approximate amount of the license fees, together with penalties and interest, for which such company may be liable as estimated by the department. Notice of such assessment shall be given by certified mail, and unless a report conforming to the requirements of this section is filed within 15 days of such notice, such estimated assessment shall become final. Thereafter the light, heat and power company assessed shall be forever barred from questioning the correctness of the same in any action or proceeding.
(7) Statements. Every light, heat, and power company shall, on or before March 1 in each year, make and return to the department, in the form and upon the forms that the department prescribes, a true statement of the operation of the company’s business during the preceding calendar year, including provision of the “amount shown in the account plus leased property” for purposes of the payment to municipalities and counties under s. 79.04. The statement shall be certified by the president and treasurer of the company or 2 of the company’s principal officers. For sufficient reason shown, the department may, upon written request, allow any further time for making and filing the statement that the department considers necessary but not to exceed 30 days. If any company fails to file the statement within the time prescribed or as extended under this subsection, the department shall add to the taxes due from that company $25, and no company may contest the imposition of that penalty in any action or proceeding.
(8) Transfer of ownership. If any light, heat or power company discontinues service through sale, merger or abandonment of its property or otherwise, the company acquiring that property or undertaking to provide service in the area of the former company shall assume the license fees due under this section, but the liability of the acquiring company is limited to those license fees which have accrued from January 1 of the previous calendar year to the date of the order of the public service commission approving the sale, merger or discontinuance of service.
(9) Property subject to local tax. The license fees imposed by this section upon the gross revenues of light, heat and power companies as defined in sub. (1) (e) shall be in lieu of all other taxes on all property used and useful in the operation of the business of such companies in this state, except that the same shall be subject to special assessments for local improvements. If a general structure is used and useful in part in the operation of the business of those companies in this state and in part for nonoperating purposes, the license fees imposed by this section are in place of the percentage of all other taxes on the property that fairly measures and represents the extent of the use and usefulness in the operation of the business of those companies in this state, and the balance is subject to local assessment and taxation, except that the entire general structure is subject to special assessments for local improvements. Property under s. 76.025 (2) shall not be taxed under this section, but shall be subject to local assessment and taxation.
(10) Standing to challenge assessment. In case any light, heat or power company fails to make a report as required by sub. (7) within the time required, the department may enter an assessment against that company in a sum representing the approximate amount of the license fees, together with penalties and interest, for which that company may be liable as estimated by the department. Notice of that assessment shall be given by certified mail, and unless a report conforming to the requirements of this section is filed within 15 days of that notice, that estimated assessment shall become final. Thereafter the light, heat or power company assessed shall be forever barred from questioning the correctness of the assessment in any action or proceeding.
(11) Payment before contesting. No action or proceeding, except a petition for redetermination under sub. (4), may be brought by a light, heat or power company against this state to contest any assessment of a tax under this section unless the taxpayer first pays to this state the amount of tax assessed. If the taxpayer prevails in an action or proceeding, this state shall settle with the taxpayer, including payment of interest at 3 percent per year on the amount of the money paid from the date of payment until the date of judgment.
