Yes, if the goods purchased are being shipped to you in Joplin and would be subject to a sales tax if purchased at retail, then they may be subject to the use tax. On June 21, 2018, the U.S. Supreme Court ruled in the South Dakota vs. Wayfair case overturning the previous ruling that exempted out-of-state vendors without a physical presence in the state from collecting the use tax. This significant ruling means online retailers may now be required to collect and remit any applicable sales and use taxes. However, municipalities must have a use tax in place to capture the revenue from this decision. If you physically purchase something from a retailer in another city such as Bentonville, AR or Miami, OK, the use tax would not apply because you would have paid the sales tax of the community you are located at the time of purchase.
