Why are mapped tax codes not being used in Dynamics GP?


The default tax code, P0000000, is being passed on invoices even though the item class is mapped to a different tax code in Dynamics GP.  


Microsoft Dynamics GP


  • First make sure your item cards still have the correct tax code mapped
  • Then make sure that the Enable Item Tax Class Mapping option is enabled in your Dynamics GP AvaTax configuration.
    • To get there and make this change please log in as an SA
    • Click Microsoft GP menu > Tools > Setup > System > Avatax > Configuration
      • Under General options, click Enable Item Tax Class Mapping.
  • Next make sure the items are not mapped in the Admin Console to a different tax code
