For Tax Accounts that you want to use in the tax templates, you must mention
them as type “Tax” in your Chart of Accounts.

Similar to your Sales Taxes and Charges Template is the Purchase Taxes and
Charges Master. This is the tax template that you can use in your Purchase
Orders and Purchase Invoices.
