Tax-rate mapping
Tax class versus TaxPack reporting type
A WooCommerce tax class controls checkout configuration, while TaxPack's type is a reporting label for a stored rate ID.
Inspect the source record
Inspect the product's tax class and the applicable WooCommerce rate row separately. Then inspect the actual tax line on a representative order.
Build a focused report
Map the rate ID to the reviewed GST, HST, PST, QST, or RST category without changing the WooCommerce class or rate.
Read the result
TaxPack groups recorded amounts by explicit type and selected province; it does not use its mapping to alter checkout calculations.
A concrete example
A Standard class order can contain a rate ID that you classify as GST for reporting. The class name is not the tax type itself.
Avoid this mistaken conclusion
Do not edit WooCommerce tax classes to make a historical TaxPack report look different. Mapping is a read-only reporting choice.
