For instance, your business is located in Atlanta, Missouri, and you make a sale to a buyer in Irondale, Missouri. Then, you should charge the buyer the sales tax rate at your Atlanta location.

• Interstate Missouri sales: For interstate sales, you should charge the sales tax rate at your buyer’s location.
