How to Collect Sales Tax in Mount Carroll

Since Illinois uses origin-based sales tax sourcing for intrastate sales and destination-based sales tax sourcing for interstate sales, the same applies to Mount Carroll as well. According to Illinois sales tax law, here’s how you can collect sales tax on:

• Intrastate Illinois sales: A sale is considered intrastate if it ships from an origin in Illinois to a buyer's address in Illinois. Illinois is an ‘origin-based’ sales tax sourcing state. This means that if both the seller’s and buyer’s address is in Illinois, you would charge the sales tax rate of the sale’s origination point. For instance, your business is located in North Pekin Village, Illinois, and you make a sale to a buyer in Mount Carroll, Illinois. Then, you’d charge the buyer the sales tax rate at your North Pekin Village location.

• Interstate Illinois sales: A sale is considered interstate if the item ships from outside Illinois and the seller isn’t otherwise “engaged in a business” in the state. In such cases, you’d generally charge the sales tax rate at your buyer’s location. For instance, if your business is located in Leander, Idaho, and you sell to a buyer in Mount Carroll, Illinois, you should charge the buyer the Mount Carroll sales tax rate.
