Tax code

Element type: Required

Endpoints/models used:LineItemModel

Your UI must include a method for allowing users to specify a tax code for each line item in a transaction. You can use your own tax code mapping or you can use standard Avalara tax codes. For a full list of tax codes, run the ListTaxCodes API, or you can use the Avalara Tax Code Search tool.

Tax codes are specified using the taxCode field on the LineItemModel. This field is optional for users. If a taxCode isn't specified, then AvaTax will treat that item as a taxable item. More information about Avalara tax codes is available in the Avalara tax codes article in the Knowledge Center.
