On a Unit Deal in Blackpurl, Deal Options default to the same tax rate as the unit. This article explains how to override that default so that specific option types — such as fees — are taxed according to their own individual records instead.
How Deal Option Taxes Work by Default
When you create a Unit Deal and mark it as taxable, all Deal Options and fees added to that deal automatically inherit the same applicable tax. You can also choose to base the tax on the customer's address. The deal's tax settings apply to every option type unless you change them.
Overriding the Tax for Specific Option Types
To have certain Deal Options taxed differently from the unit, open the Tax these options the same way: section within the Option Type area of the Unit Deal. This section lists each option type that currently follows the deal's tax settings.
Uncheck any option type you want to exclude from the deal's tax. An unchecked option type will instead use the tax rate recorded on its own individual record.
For example, if you uncheck Fees, any fee added to that Unit Deal will be taxed according to the tax setting on the relevant fee record — not the deal-level tax.
How the Option Record's Tax Is Applied
When an option type is unchecked from the deal's tax, Blackpurl looks up the tax on that option's own record and applies it to the line item. For example, a fee record such as Charged To Customer Freight will carry its own tax configuration, and that is what appears on the deal when Fees are excluded from the deal-level tax.
