There are a large number of items that do not have any tax codes mapped to them. We are using a Streamlined Sales Tax (SST) account with Avalara.
- Any item that does not have a valid SST AvaTax system code mapped to it will be defaulted to "P0000000", which is taxable everywhere.
NOTE: SST participants cannot use custom tax codes. Instead, they should map items to Avalara tax codes.
