Distributors, monthly returns
Wis. Stat. § 139.77
in effect(1) On or before the 15th day of each month, every distributor with a place of business in this state shall file a return showing the quantity, including milliliters in the case of a vapor product, and taxable price of each tobacco product or vapor product brought, or caused to be brought, into this state for sale; or made, manufactured or fabricated in this state for sale in this state, during the preceding month. Every distributor outside this state shall file a return showing the quantity, including milliliters in the case of a vapor product, and taxable price of each tobacco product or vapor product shipped or transported to retailers in this state to be sold by those retailers during the preceding month. At the time that the return is filed, the distributor shall pay the tax.
(2) As soon as practicable after any return is filed, the department shall examine each return and correct it, if necessary, according to its best judgment and information. If the department finds that any amount of tax is due from the taxpayer and unpaid, it shall notify the taxpayer of the deficiency, stating that it proposes to assess the amount due together with interest and penalties. If a deficiency disclosed by the department’s examination cannot be allocated to one or more particular months, the department shall notify the taxpayer of the deficiency, stating its intention to assess the amount due for a given period without allocating it to any particular months.
(3) If, within 60 days after the department sends notice of the proposed assessment, the taxpayer files a protest to the proposed assessment and requests a hearing on it, the department shall give notice to the taxpayer of the time and place fixed for the hearing, shall hold a hearing on the protest, and shall issue a final assessment to the taxpayer for the amount found to be due as a result of the hearing. If the taxpayer does not file a protest within 60 days, the department shall issue a final assessment to the taxpayer. In any action or proceeding in respect to the proposed assessment, the taxpayer has the burden of establishing the incorrectness or invalidity of any final assessment made by the department.
(4) If any taxpayer required to file any return fails to do so within the time prescribed, the taxpayer shall, on the written demand of the department, file the return within 20 days after the department sends the demand and at the same time pay the tax due on its basis. If the taxpayer fails within that time to file the return, the department shall prepare the return from the department’s own knowledge and from the information that the department obtains and on that basis shall assess a tax that the taxpayer shall pay within 10 days after the department sends to the taxpayer a written notice of the amount and a demand for its payment. In any action or proceeding in respect to the assessment, the taxpayer has the burden of establishing the incorrectness or invalidity of any return or assessment made by the department because of the failure of the taxpayer to make a return.
(5) All taxes are due not later than the 15th day of the month following the calendar month in which they were incurred.
(7) The department may recover the amount of any tax due and unpaid, interest and any penalty in a civil action. The collection of the tax, interest or penalty is not a bar to any prosecution under s. 139.85 (1).
