Can shipping be included in the tax calculation?

By default, TitleLeaf does not include shipping in the base amount used to calculate the tax. The default can be overridden through the Postal Codes module (Admin > Management > Geography > Postal Codes). For a given postal code, set the “Tax Shipping?” field to “Yes” for the shipping amount to be included in the tax calculation.

To update postal codes in bulk, use the “postal_codes” ingestion template. Populate the “tax_shipping” column with “Yes” or “1”.
