How to Collect Sales Tax in St. Louis

Since Missouri uses origin-based sales tax sourcing for intrastate sales and destination-based sales tax sourcing for interstate sales, the same applies to St. Louis as well:

• Intrastate Missouri sales: Missouri is an ‘origin-based’ sales tax sourcing state. This means that sales tax is charged at the rate of the location where the order originates.  

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

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

For instance, if your business is located in Los Angeles, California, and you sell to a buyer in St. Louis, Missouri, you should charge the buyer the St. Louis sales tax rate.
