Why does the Detailed Sales Tax Analysis ask for an address?

The Detailed Sales Tax Analysis will ask for an address because of the sourcing in particular states, specifically for origin-based states. 

• Origin-based states calculate sales tax differently when you are shipping from within - and to - an address located in that state. 
• To better determine the Expected Sales Tax Due for those states if you don't have a physical location within the state, we recommend checking out the individual State Sales Tax Reports from your Dashboard. 
• Those reports will have a breakdown of your sales with sales tax logic and state-specific decisions applied, including rounding, sourcing, and handling of refunds to accurately determine the Expected Sales Tax Due.
