It is a Marketplace seller’s responsibility to remit sales tax (and product taxes and fees) to the applicable taxing jurisdiction. Marketplace sellers have the option of having Walmart collect taxes and fees on the Marketplace seller’s behalf. Using the partner tools, you will specify the state(s) and local jurisdictions where you have a tax collection and remittance obligation. See the Marketplace Retailer Agreement and Tax Policy for more information.
