76.07 (2) Relation to state valuation; description. The value of the property of each of said companies for assessment shall be made on the same basis and for the same period of time, as near as may be, as the value of the general property of the state is ascertained and determined.

No return is required with respect to conveyances exempt under s. 77.25 (2) unless the transferor is also a lender for the transaction.

77.52 (7) Every person desiring to operate as a seller within this state who holds a valid certificate under s. 73.03 (50) shall file with the department an application for a permit for each place of operations. Every application for a permit shall be made upon a form prescribed by the department and shall set forth the name under which the applicant intends to operate, the location of the applicant's place of operations, and the other information that the department requires. If an owner elects under s. 77.58 (3) (a) to file a separate electronic return for each of the owner's disregarded entities, each disregarded entity is an applicant under this subsection. Except as provided in sub. (7b), the application shall be signed by the owner if a sole proprietor; in the case of sellers other than sole proprietors, the application shall be signed by the person authorized to act on behalf of such sellers. A nonprofit organization that has a sales price taxable under s. 77.54 (7m) shall obtain a seller's permit and pay taxes under this subchapter on all taxable sales prices received after it is required to obtain that permit. If that organization becomes eligible later for the exemption under s. 77.54 (7m) except for its possession of a seller's permit, it may surrender that permit.

77.54 (61) (intro.) The sales price from the sale of to, and the storage, use, or other consumption of the following by, a person primarily engaged, as determined by the department, in commercial printing, book printing, or support activities for printing described under 323111, 323117, and 323120 of the North American Industry Classification System, of any of the following:

77.59 (3) No determination of the tax liability of a person may be made unless written notice of the determination is given to the taxpayer person within 4 years after the due date of the taxpayer's person's Wisconsin income or franchise tax return that corresponds to the date the sale or purchase was completed or, if exempt, within 4 years of the 15th day of the 4th month of the year following the close of the calendar or fiscal year, that corresponds to the date the sale or purchase was completed; within 4 years of the dissolution of a corporation; or within 4 years of the date any sales and use tax return required to be filed for any period in that year was filed, whichever is later. The notice required under this paragraph shall specify whether the determination is an office audit determination or a field audit determination, and it shall be in writing. If the department is unable to obtain service by mail, publication of it as a class 3 notice, under ch. 985, shall be service of notice in any case where notice is required under this subchapter.

77.59 (4) (a) Except as provided in sub. (3m), at any time within 4 years after the due date of a person's corresponding Wisconsin income or franchise tax return that corresponds to the date the sale or purchase was completed or, if exempt, within 4 years of the 15th day of the 4th month of the year following the close of the calendar or fiscal year for which that person files a claim that corresponds to the date the sale or purchase was completed, that person may, unless a determination by the department by office audit or field audit of a seller has been made, and unless a determination by office audit of a buyer other than an audit in which the tax that is the subject of the refund claim was not adjusted has been made, and unless a determination by field audit of the buyer has been made, file with the department a claim for refund of taxes paid to the department by that person. If the amount of the claim is at least $50 or if either the seller has ceased doing business, the buyer is being field audited, or the seller may no longer file a claim, the buyer may, within the time period under this subsection, file a claim with the department for a refund of the taxes paid to the seller. A claim is timely if it fulfills the requirements under s. 77.61 (14). A buyer may claim a refund under this paragraph only on a form prescribed by the department, only by signing that form, and only if the seller signs the form unless the department waives that requirement. If both a buyer and a seller file a valid claim for the same refund, the department may pay either claim. The claim for refund shall be regarded as a request for determination. The determination thus requested shall be made by the department within one year after the claim for refund is received by it unless the taxpayer person has consented in writing to an extension of the one-year time period prior to its expiration.

(b) A claim for refund that is not to be passed along to customers under sub. (8m) may be made within 2 years of the determination of a tax assessed by office audit or field audit and paid if the tax was not protested by the filing of a petition for redetermination. No claim for refund may be allowed with regard to items that were not adjusted in the office audit or field audit. A claim is timely if it fulfills the requirements under s. 77.61 (14). No claim may be allowed under this paragraph for any tax self-assessed by the taxpayer. If a claim is filed under this paragraph, the department may make an additional assessment in respect to any item that was a subject of the prior assessment.
