Details of How Tax is Calculated

When ChargeOver calculates tax with Zip2Tax, we follow the following process:

  • Grabs the billing or shipping address, depending on your settings
  • Ask Zip2Tax for the correct sales tax rate for the postal code
  • Saves the tax percentage from that tax rate to the invoice, and calculates the tax from that

ChargeOver calculates tax at the time the invoice is added or edited. The address that exists on the invoice as that time will be used.

If you later edit the customer's address, new invoices will use the new address and thus will calculate tax based on the new postal code.
