WooCommerce tax settings
Compare reports before and after a tax setting change
A change to checkout tax settings affects new orders but should not cause TaxPack to reprice historical orders.
Inspect the source record
Record the date of the setting change and inspect orders on both sides for their stored rate IDs and tax lines.
Build a focused report
Run adjacent TaxPack periods with the same mapping and address basis, then compare the detail exports.
Read the result
Different historical and new totals reflect what WooCommerce recorded at each time, not a recalculation with today's configuration.
A concrete example
If shipping tax was enabled in October, September orders can still have their original shipping-tax detail unchanged.
Avoid this mistaken conclusion
Do not compare two periods as if the checkout setup were identical when the configuration actually changed.
