Why is the tax on the credit different than the original invoice?


When I posted a credit, the tax amount did not match the original invoice.

  • Tax on the credit and original invoice will match if the tax date, items, amounts, addresses, and customer code match, also check:
    • Exemption: Customer could have an exemption change, confirm exemption status is the same as on original
    • Nexus: Your company nexus setting could have changed
    • Item Mapping: Check that all items use the same tax code as was on the original sale
    • Rate Changes: Check that the rate has not changed from the time the original invoice was submitted


Note: Changes in nexus include changes in which jurisdictions are selected or whether Sale Tax or Sales or Sellers Use tax is selected.
