Illinois is considered an “Origin States” for sales tax calculation purposes. When a sale takes place in an Origin State:
- The zip code of the store’s physical presence in that state is used for tax rate determination - not the customers shipping address.
- In other words, the customer will pay the State, County AND Municipal Tax of the merchants physical presence (as opposed to the customer’s shipping address).
- This will only apply to Orders where the Shipping Address is in Illinois - orders out of state continue to be exempt from taxes.
