eCart tax help...
We are setting up an ecommerce site and are selling products to the 50 states...
As an example, to sell a product in Aberdeen, Washington the combined tax is .083 as opposed to Airway Heights, Washington which is .087 as opposed to Denver Colorado which is .0825 and so on and so fourth...
Where do I set up the 320 different Washington alone tax rates let alone the rest of the US tax rates? Inside the eCart object? The Checkout Wizard? an external xml file? crayon?
Thanks,
Ted
