States with Origin sourcing or Special sourcing rules

A list of special sourcing states and states that use origin sourcing.




Sourcing determines how tax should be applied to a transaction. Tax rules are applied based on the origin or destination address, depending on state laws. 

Watch our "What is Sourcing" video.


Origin Sourcing - Apply sales tax to products based on their point of origin, for intrastate transactions (within the same state).

Example: Product shipped from Springfield to Chicago within the state of Illinois. Tax is based on the Springfield address, the origin.

Note: For services, AvaTax typically applies tax based on the destination address.)

Mixed Sourcing - The tax rate depends on the product, service, or unique jurisdiction rules.
