Did you make any taxable purchases from out-of-state firms during the year on which sales and use tax was not charged? If yes, you must report Wisconsin sales and use tax on these purchases if they were stored, used, or consumed in Wisconsin. You must also report sales and use tax on taxable purchases from a retailer located in another country, regardless of whether you were charged any tax for that country or any duty by the U.S. Customs Service.
Taxable purchases include furniture, carpet, clothing, computers, books, CDs, DVDs, video tapes, artwork, antiques, jewelry, coins purchased for more than face value, etc.
Example You purchased $300 of clothing through a catalog or over the Internet. No sales and use tax was charged. The clothing was delivered in a county with a 5% tax rate. You are liable for $15 Wisconsin tax ($300 x 5% = $15) on this purchase.
